Adding navigation drawer from second activity to activity_main. Using .opendrawer in main activity to open second

I have created a project int activity_main and want to add a Navigation drawer to it.
I have gone into the java folder. Right click > new > Actvity > Navigation Drawer activity.
Note: I DON't have an action bar, to create the menu button(3 stacked lines)
Now I don't know how to actually open the navigation drawer over activity_main, without the app crashing.
Thanks.
I've tried doing an on click listener with a button which has
the drawer layout defined as dl (DrawerLayout dl = (DrawerLayout)findviewbyIOd(R.id.Drawer_layout))
and have done
dl.openDrawer(Gravity.LEFT);
have tried putting the code from the NavDrawer activity into the activity_main, but app won't start.
public class MainActivity extends AppCompatActivity implements CompoundButton.OnCheckedChangeListener {
Switch OnOff;
EditText editText;
int NumberPicked;
int NumberPicked2;
private DrawerLayout dl;
private ActionBarDrawerToggle abdt;
Values[] troughvals = new Values[8];
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BobbleSelector BS = new BobbleSelector();
final DrawerLayout dl = (DrawerLayout)findViewById(R.id.dl);
Button btnChange = (Button) findViewById(R.id.btnChange);
Switch OnOff = (Switch) findViewById(R.id.OnOff);
NumberPicker numberPicker2 = findViewById(R.id.numberPicker2);
NumberPicker numberPicker = findViewById(R.id.numberPicker);
numberPicker.setMinValue(00);
numberPicker2.setMinValue(00);
numberPicker2.setMaxValue(23);
numberPicker.setMaxValue(23);
btnChange.setOnClickListener( new View.OnClickListener(){
public void onClick(View v){
dl.openDrawer(Gravity.LEFT);
}
});
OnOff.setTextOff("On");
OnOff.setTextOn("Off");
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return abdt.onOptionsItemSelected(item) || super.onOptionsItemSelected(item);
}
public void handleSwitchClick(View view) {
Switch s = (Switch) view;
boolean isChecked = s.isChecked();
}
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked){
switch (compoundButton.getId()){
case R.id.OnOff:
break;
}
}
}
Note: have disabled fab, because it could not be found in my project.
I have created a custom Menu for the Navigation Drawer
public class BobbleSelector extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bobble_selector);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Button fab = findViewById(R.id.btnChange);
// fab.setOnClickListener(new View.OnClickListener() {
// #Override
// public void onClick(View view) {
// Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
// .setAction("Action", null).show();
// }
// });
DrawerLayout drawer = findViewById(R.id.dl);
NavigationView navigationView = findViewById(R.id.nav_view);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = findViewById(R.id.dl);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.bobble_selector, menu);
return true;
}
#Override

}
return super.onOptionsItemSelected(item);

int id = item.getItemId();
DrawerLayout drawer = findViewById(R.id.dl);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}

Expected to open drawer with the changebutton.openDrawer(Gravity.Left) But crashes the app.

Found I needed to move the code relating to the nav bar to the bottom of OnCreate and set the "SetContentView()" to be the layout for the Navigation bar.
Then it worked perfectly.
Before
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = findViewById(R.id.btnChange);
drawer = findViewById(R.id.dl);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawer, R.string.navigation_drawer_open,R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
//Not nav

numberPicker2.setMinValue(00);
numberPicker2.setMaxValue(23);
numberPicker.setMaxValue(23);
OnOff.setTextOff("On");
OnOff.setTextOn("Off");
//not nav
}
After

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = findViewById(R.id.btnChange);
//Not nav
Switch OnOff = (Switch) findViewById(R.id.OnOff);

Change background color of the screen [duplicate]

This question already has answers here:
Android: Changing Background-Color of the Activity (Main View)
(10 answers)
Closed 6 years ago.
I have created a string in action bar. What I want here is, when I click on the red button, background will change its color to red. Could anyone tell me how I can achieve this? Here is my Main.java file:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
setFrameVisibility(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.colourred) {
return true;
}
return super.onOptionsItemSelected(item);
}
Here is the xml file
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/colourred"
android:orderInCategory="100"
android:title="#string/colour_red"
app:showAsAction="never" />
</menu>

#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.colourred) {
//toolBar.setBackgroundColor(Color.RED);
getWindow().getDecorView().setBackgroundColor(Color.RED);
getWindow().getDecorView().setBackgroundColor(Color.parseColor("#FFCC33"));
//or like below with color code
//toolBar.setBackgroundColor(Color.parseColor("#FFCC33"));
return true;
}else if(id==R.id.color_green){
getWindow().getDecorView().setBackgroundColor(Color.parseColor("#green_color_code"));
}else if(id==R.id.other_id){
getWindow().getDecorView().setBackgroundColor(Color.parseColor("#other_color_code"));
}
}
And if you wish to change activity background color then visit this How to set background color of Activity to white programmatically?
getWindow().getDecorView().setBackgroundColor(Color.WHITE);//change activity bg color

In onOptionsItemSelected, if id == R.id.colourred then change color by setting the action bar
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color
.parseColor("red color code")));
Background of app screen in onOptionsItemSelected
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.colourred) {
findViewById(R.id.root layout id).setBackgroundColor(Color.RED);
return true;
}

Try inserting in your code
#Override
public boolean onOptionsItemSelected(MenuItem item) {
...
//noinspection SimplifiableIfStatement
if (id == R.id.colourred) {
getWindow().getDecorView().setBackgroundColor(Color.RED);
return true;
}
...
}
Since this if tells u that your 'colloured' item in menu was selected,
so in there you want to handle it.

Just add this line to your onOptionsItemSelected:
getWindow().getDecorView().setBackgroundColor(Color.RED);
Your Main.java will look something like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
setFrameVisibility(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.colourred) {
getWindow().getDecorView().setBackgroundColor(Color.RED);
}
return super.onOptionsItemSelected(item);
}

Android : Unable to integrate Drawer navigation because already calling extends for Google-Maps

I am working on an Android project in which I would like to add Drawer functionality, for which I already have classes and all ready.
THe problem is the Drawer code works by extends or extending the class which wants to add a drawer, and similarly my GoogleMaps code works in the same way. But because of Multiple-inheritance, I cannot extend 2 classes.
What should I do?
Google-maps code :
public class MapsActivity extends FragmentActivity {
GoogleMap googleMap;
SharedPreferences sharedPreferences;
int locationCount = 0;
private RestaurantServiceImpl restaurantService = new RestaurantServiceImpl();
List<RestRestaurant> restRestaurantList = new ArrayList<>();
GPSTracker gps;
double longitude, latitude;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mapsact);
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting GoogleMap object from the fragment
googleMap = fm.getMap();
// Enabling MyLocation Layer of Google Map
googleMap.setMyLocationEnabled(true);
// Opening the sharedPreferences object
sharedPreferences = getSharedPreferences("location", 0);
// Getting number of locations already stored
locationCount = sharedPreferences.getInt("locationCount", 0);
// Getting stored zoom level if exists else return 0
String zoom = sharedPreferences.getString("zoom", "12");
gps = new GPSTracker(MapsActivity.this);
if (gps.canGetLocation()) {
longitude = gps.getLongitude();
latitude = gps.getLatitude();
restRestaurantList = this.restaurantService.getRestaurantsByLocation(longitude,latitude);
double lat=0, longi=0;
for(RestRestaurant restRestaurant : restRestaurantList){
drawMarker(new LatLng(restRestaurant.getLatitude(),restRestaurant.getLongitude()), restRestaurant.getRestaurantName(), restRestaurant.getRestaurantId());
lat = restRestaurant.getLatitude();
longi = restRestaurant.getLongitude();
}
googleMap.moveCamera(CameraUpdateFactory.newLatLng(new LatLng(lat,longi)));
// Setting the zoom level in the map on last position is clicked
googleMap.animateCamera(CameraUpdateFactory.zoomTo(Float.parseFloat(zoom)));
} else {
gps.showSettingsAlert();
}
googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker) {
int restoId = Integer.valueOf(marker.getSnippet());
Intent intent = new Intent(MapsActivity.this, MenuCardList.class);
intent.putExtra("restaurantid", restoId);
startActivity(intent);
finish();
return true;
}
});
}
This class I need to extend to add a drawer :
public class DrawerLoader extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title
private CharSequence mTitle;
private ArrayList<DrawerModel> navDrawerItems;
private DrawerListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawerlayout);
}
public void set(String[] navMenuTitles, TypedArray navMenuIcons) {
mTitle = mDrawerTitle = getTitle();
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
navDrawerItems = new ArrayList<DrawerModel>();
If any more information is required, kindly let me know.

Ignoring all your work regarding a navigation drawer, this would be my preferred solution, since There is no need for a extra Fragment, List filling, new classes....
1, Create a nav_menu.xml (in menues folder):
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group
android:checkableBehavior="single">
<item
android:id="#+id/drawer_home"
android:checked="true"
android:icon="#drawable/ic_home_black_24dp"
android:title="Home"/>
<item
android:id="#+id/drawer_favourite"
android:icon="#drawable/ic_favorite_black_24dp"
android:title="Favourites"/>
<item
android:id="#+id/drawer_settings"
android:icon="#drawable/ic_settings_black_24dp"
android:title="Settings"/>
</group>
2, Wrap your activites layout with a DrawerLayout:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Your activity layout here-->
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/drawer_header"
app:menu="#menu/nav_menu"/>
</android.support.v4.widget.DrawerLayout>
3, Update your activities java code:
//If you have a toolbar (recommended!)
final Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
//and finally the Navigation View Code:
final NavigationView navigation = (NavigationView) findViewById(R.id.navigation);
navigation.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
navigation.setCheckedItem(menuItem.getItemId());
drawerLayout.closeDrawers();
switch (menuItem.getItemId()) {
case R.id.drawer_home:
//open fragment home
return true;
case R.id.drawer_favourite:
//open fragment favourite
return true;
case R.id.nav_drawer_channels:
showFragment(2);
return true;
case R.id.drawer_settings:
//open settings
return true;
}
return false;
}
});
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(
this,
drawerLayout,
toolbar,
R.string.drawer_open, //simply a String "open"
R.string.drawer_close) { //simply a String "close"
public void onDrawerClosed(View view) {
super.onDrawerOpened(drawerLayout);
drawerToggle.syncState();
}
public void onDrawerOpened(View drawerView) {
super.onDrawerClosed(drawerLayout);
drawerToggle.syncState();
}
};
drawerLayout.setDrawerListener(drawerToggle);
drawerToggle.syncState();
//And, last but not least, open the drawer with a Click on 'home'
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
drawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
And you are done! No messing with extra fragment, unnecessary and messy code.

ActionBarSherlock menu ForceOverflow not showing

My problem is that when you open the app is not shown the overflow menu in the actionbar.

</application>
Please if you need some more information to answer, ask me
(I have not yet allowed to post images to show you my app)
Sorry if I made a mistake when posting, also for my English, I notice that I am beginner coding.
EDIT:
I think that solves the fact that the menu does not appear on the actionbar with this code and deleting the menu.xml:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
SubMenu subMenu = menu.addSubMenu("Más");
subMenu.add("Volver");
subMenu.add("Contacto");
subMenu.add("Salir");
subMenu.getItem().setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
return true;
}
And added this in the onOptionsItemSelected already have in the MainActivity.java:
if (item.getTitle().toString().equalsIgnoreCase("Publicá!")) {
Intent in = new Intent(getApplicationContext(),Publica.class);
startActivity(in);
Toast.makeText(this, "Publicá tu Negocio/Local/Emprendimiento", Toast.LENGTH_LONG).show();
} if (item.getTitle().toString().equalsIgnoreCase("Contacto")) {
Intent in = new Intent(getApplicationContext(),Contacto.class);
startActivity(in);
Toast.makeText(this, "Contactate y reportanos ...", Toast.LENGTH_LONG).show();
}
if (item.getTitle().toString().equalsIgnoreCase("Salir")) {
Intent i = new Intent(); i.setAction(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_HOME); i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i); android.os.Process.killProcess(android.os.Process.myPid());
Toast.makeText(this, "<-- Busca lo que necesitas", Toast.LENGTH_LONG).show();
}
Now i Have something like This
But not know to generate the menu on the actionbar be an icon instead of text like "Type".
That is my problem now.

This is what you need to do with the item tags
android:showAsAction=["ifRoom" | "never" | "withText" | "always" | "collapseActionView"]
always will always show you menus, never will let your menu item to come in the overflow mode..
set
android:showAsAction="never"
look here for more description.

How do I add buttons, switches etc. to an android app drawer?

How do I add buttons, switches, seekbars etc. to an android app drawer?
I know how to add text to the listview but I'm finding the above very difficult. I have my current app drawer below. What changes would you suggest to accomplish the above.
Code:
MainActivity
public class MainActivity extends Activity {
// Within which the entire activity is enclosed
DrawerLayout mDrawerLayout;
// ListView represents Navigation Drawer
ListView mDrawerList;
// ActionBarDrawerToggle indicates the presence of Navigation Drawer in the action bar
ActionBarDrawerToggle mDrawerToggle;
// Title of the action bar
String mTitle="";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = (String) getTitle();
// Getting reference to the DrawerLayout
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.drawer_list);
// Getting reference to the ActionBarDrawerToggle
mDrawerToggle = new ActionBarDrawerToggle( this,
mDrawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close){
/** Called when drawer is closed */
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
/** Called when a drawer is opened */
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle("Select a river");
invalidateOptionsMenu();
}
};
// Setting DrawerToggle on DrawerLayout
mDrawerLayout.setDrawerListener(mDrawerToggle);
// Creating an ArrayAdapter to add items to the listview mDrawerList
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
getBaseContext(),
R.layout.drawer_list_item ,
getResources().getStringArray(R.array.rivers)
);
// Setting the adapter on mDrawerList
mDrawerList.setAdapter(adapter);
// Enabling Home button
getActionBar().setHomeButtonEnabled(true);
// Enabling Up navigation
getActionBar().setDisplayHomeAsUpEnabled(true);
// Setting item click listener for the listview mDrawerList
mDrawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent,
View view,
int position,
long id) {
// Getting an array of rivers
String[] rivers = getResources().getStringArray(R.array.rivers);
//Currently selected river
mTitle = rivers[position];
// Creating a fragment object
RiverFragment rFragment = new RiverFragment();
// Creating a Bundle object
Bundle data = new Bundle();
// Setting the index of the currently selected item of mDrawerList
data.putInt("position", position);
// Setting the position to the fragment
rFragment.setArguments(data);
// Getting reference to the FragmentManager
FragmentManager fragmentManager = getFragmentManager();
// Creating a fragment transaction
FragmentTransaction ft = fragmentManager.beginTransaction();
// Adding a fragment to the fragment transaction
ft.replace(R.id.content_frame, rFragment);
// Committing the transaction
ft.commit();
// Closing the drawer
mDrawerLayout.closeDrawer(mDrawerList);
}
});
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
/** Handling the touch event of app icon */
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
/** Called whenever we call invalidateOptionsMenu() */
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// If the drawer is open, hide action items related to the content view
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Activity_Layout
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="#+id/drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>

You can use this library for your drawer library
or if you want this drawer then put one linearlayout and then put you views inside that.
SlidingMenu menu = new SlidingMenu(this);
menu.setMode(SlidingMenu.LEFT);
menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);
menu.setShadowWidthRes(R.dimen.shadow_width);
menu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
menu.setFadeDegree(0.35f);
menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
menu.setMenu(R.layout.side_panel);
Now in the side panel layout put your views in side that now for view side panel use this:
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
int itemId = item.getItemId();
switch (itemId) {
case android.R.id.home:
if (menu != null) {
menu.toggle();
}
break;
}
return true;
}
for initializing side panel data use this:
menu.findViewById(R.id.your_view_id).setOnClickListener(this);
and override onclick event and handle that you want.
for further information see the example in the github.
