Handling click event of switch widget on action bar

Handling click event of switch widget on action bar - java

This is how I added a switch widget to the action bar. I'm already playing with it. But I'm not knowing how to respond to the click events.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.map, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
System.out.println("actionbar clicked");
// Handle item selection
if (item.getItemId()==R.id.myswitch) {
Switch actionView = (Switch)item.getActionView();
actionView.setOnCheckedChangeListener(new OnCheckedChangeListener(){
#Override
public void onCheckedChanged(CompoundButton buttonView, final boolean isChecked) {
status = isChecked;
System.out.println(status);
}
});
return true;
}
return super.onOptionsItemSelected(item);
}
This is my switch layout and map resource file
switch_status.xml
<?xml version="1.0" encoding="utf-8"?>
<Switch
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:showText="true"
android:textOff="Free"
android:textOn="Booked" />
map.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" >
<item
android:id="#+id/myswitch"
android:showAsAction="always"
android:title=""
android:actionLayout="#layout/switch_status" />
</menu>
While clicking the switch, It is changing its state, but I cannot see even one msg on the console like "actionbar clicked" & "true" / "false". And there is no error either.
I'm not sure weather this is the correct way of handling clicks on actionbar. If any one can help me with this code, it will be really nice.
Thankyou

Best way for do this using Toolbar .
In Toolbar you can add any view and control this.

You don't need to set a OnCheckedChangeListener, onOptionsItemSelected is a "onClickListener"
use switch for this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
System.out.println("actionbar clicked");
// Handle item selection
switch (item.getItemId()) {
case R.id.myswitch:
System.out.println(((Switch)item.getActionView()).isChecked());
break;
}
return super.onOptionsItemSelected(item);
}

I had the same issue and achieved by following below technique
Added onClick method for switch like below
<Switch
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:showText="true"
android:textOff="Free"
android:textOn="Booked"
android:onClick="onSwitch"
/>
Implement onSwitch method in Activity as below:
public void onSwitch(View view) {
Switch androidSwitch = findViewById(R.id.switch1);
if(androidSwitch.isChecked()){
Log.i("Test","enabled");
}else{
Log.i("Test","disabled");
}
}

How to make option menu appear on bottom of the screen?

Here is what I am trying to implement: when people click on the menu on top right corner of a toolbar, an options menu appears on bottom of the screen. See picture below:
I am not sure what method should I call for the item at the bottom. Can somebody give me some hint on how to implement this?
I implement successfully the icon in the top right menu bar with the code below. But I don't know how to show the options at the bottom of the screen, with width match_parent, and height wrap_content
onClick on the right top corner
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.edit_profile_image_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.more:
//How to show the 2 option in the bottom of screen here
return true;
}
return super.onOptionsItemSelected(item);
}

OLD ANSWER
try this attach this PopupMenu in your bottom view click event something like button click event
step 1
create a view at bootom of your layout like this
<View
android:layout_gravity="center"
android:id="#+id/myView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
step 2 create a new_menu.xml file like this
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/temp"
android:title="#string/str_menu_account_logout"
android:icon="#drawable/next"
app:showAsAction="ifRoom"></item>
</menu>
now add this code to create option menu in your java file
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.new_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.temp) {
PopupMenu popupMenu = new PopupMenu(this, findViewById(R.id.myView),Gravity.CENTER);
popupMenu.inflate(R.menu.home_menu);
popupMenu.show();
return true;
}
return false;
}

I will suggest to use the Material design App Bar(Bottom), with few modifications you can get the result.
Try this https://material.io/design/components/app-bars-bottom.html
hope this will help.

Simple.
Make a dialog with its own contents which will makeup the bottom menu.
When user clicks there above then the dialog should show but its position would be below i.e. anchored with the bottom. You can find many codes regarding how to position dialog at the bottom of the scree anchored!! SO not adding any.Hope it helps.!

Answer by #Nilesh is very elaborate and bit complicated.
Simple Solution
Create FrameLayout and arrange your buttons inside frame layout depending on your requirements. Set id -- I use id = "menu"
Set visibility to gone android:visibility = "gone"
On menubutton click
findViewById(R.id.menu).setVisibility(View.VISIBLE);
Now to make menu disappear when you click outside the menu, add an empty view or layout behind the menu. set ontouch listner. Set visibility GONE when the background view is touched.

there is no need to reinvent the wheel; use a BottomNavigationView, which is being provided by:
dependencies {
api "com.google.android.material:material:1.0.0"
}
it can be added into the layout alike this (set gone by default):
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_gravity="start"
android:visiblity="gone"
app:menu="#menu/bottom" />
the menu/bottom.xml:
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/action_search"
android:title="#string/menu_search"
android:icon="#drawable/ic_search" />
<item android:id="#+id/action_settings"
android:title="#string/menu_settings"
android:icon="#drawable/ic_add" />
</menu>
then hook into the onMenuOpened() event:
#Override
public boolean onMenuOpened(int featureId, Menu menu) {
this.mBottomNavigationView.setVisibility(View.VISIBLE);
return super.onMenuOpened(featureId, menu);
}
and also implement method onOptionsItemSelected():
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_search:
...
this.hideBottomNavigation();
return true;
case R.id.action_settings:
...
this.hideBottomNavigation();
return true;
default:
this.hideBottomNavigation();
return super.onOptionsItemSelected(item);
}
}
private void hideBottomNavigation() {
this.mBottomNavigationView.setVisibility(View.GONE);
}
BottomSheetDialogFragment would indeed be the other option available, while it does not support inflating a menu, but a fragment ...nevertheless it would merely be the same approach.

You can now use Material Design BottomAppBar
1st add this in build.gradle where all are being implemented
implementation 'com.google.android.material:material:1.0.0'
create menu
anyname.xml
2nd add coordinator layout and inside it bottomAppBaradd menu and navigation as given here
3rd Add code by initialising
private var mBottomAppBar: BottomAppBar ?= null
Then add them into the method
//bottom bar
mBottomAppBar = findViewById(R.id.bar)
mBottomAppBar?.setOnMenuItemClickListener{
when(it.itemId){
R.id.itemConfig->showConfigBottomSheetDialogFragment()
}
true
}
mBottomAppBar?.setNavigationOnClickListener{
startContentHighlightActivity()
}
}
The navigation will directly work and the menu will work according to the items you will add.

//This is click event of button
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.buttonSort:
PopupMenu popupMenu = new PopupMenu(this, findViewById(R.id.myView),Gravity.CENTER);
popupMenu.inflate(R.menu.bottom_menu);
popupMenu.show();
break;
}
This is my home_menu.xml:
<?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/bottom_menu_price"
android:title="Price low to high"
android:icon="#drawable/ic_price_low"
/>
<item
android:id="#+id/bottom_menu_price_high"
android:title="Price high to low"
android:icon="#drawable/ic_price_high"
/>
<item
android:id="#+id/bottom_menu_date"
android:title="New Added"
android:icon="#drawable/ic_date_sort"
/>
<item
android:id="#+id/bottom_menu_rate"

android:title="#string/navview_menu_item_map"
android:titleCondensed="#string/navview_menu_item_map"
android:visible="false"/>
</group>
</menu>
How can I change one <item> to be switch:
<Switch
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Switch"
android:id="#+id/switch1"
android:layout_gravity="center_horizontal" />
I am currently using the default layout:
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:menu="#menu/activity_main_drawer" />
Just Like this Image under Android Notification http://i.stack.imgur.com/M9nD7.png
I really Appreciate any feedback. Thank you.

One way I have found of doing this would be to use setActionView on the menuItem you want:
mNavigationView.getMenu().findItem(R.id.nav_connect)
.setActionView(new Switch(this));
// To set whether switch is on/off use:
((Switch) mNavigationView.getMenu().findItem(R.id.nav_connect).getActionView()).setChecked(true);
Probably want a click listener as well to change the state of the Switch:
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.nav_connect:
((Switch) menuItem.getActionView()).toggle();
return true;
}
}
}
I haven't tried, but you could probably use android:actionLayout="#layout/switch_layout" in xml and point to a custom layout you created.
Also could try using an ActionProvider which might offer a little more robustness. I haven't tried this method either though.

We can do it by the following way
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
//Get a reference to your item by id
MenuItem item = menu.findItem(R.id.menu_pick_color);
//Here, you get access to the view of your item, in this case, the layout of the item has a FrameLayout as root view but you can change it to whatever you use
FrameLayout rootView = (FrameLayout)item.getActionView();
//Then you access to your control by finding it in the rootView
YourControlClass control = (YourControlClass) rootView.findViewById(R.id.control_id);
//And from here you can do whatever you want with your control
return true;
}

If you only want to check for the changes in the switch, you can set onCheckedChangeListener only for the switch like so
((Switch) navigationView.getMenu().findItem(R.id.darkModeSwitch).getActionView())
.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked) {
Toast.makeText(MainActivity.this, "Checked", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(MainActivity.this, "Unchecked", Toast.LENGTH_SHORT).show();
}
}
});
If you want to be cool use lambda
((Switch) navigationView.getMenu().findItem(R.id.darkModeSwitch).getActionView())
.setOnCheckedChangeListener((buttonView, isChecked) -> {
if(isChecked) {
Toast.makeText(MainActivity.this, "Checked", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(MainActivity.this, "Unchecked", Toast.LENGTH_SHORT).show();
}
});

NullPointerException in android while using actionLayout in menu.xml

I want to use custom SearchView in menu of my App but I'm encountering a NullPointerException in android while using actionLayout in menu.xml
I have custom layout for menu :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/search_btn"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#android:drawable/ic_menu_search"/>
<EditText
android:id="#+id/search_et"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/search_btn"
android:layout_toLeftOf="#+id/search_btn"
android:ems="10"
android:inputType="none" >
<requestFocus />
</EditText>
and my menu.xml is :
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/search_view"
android:icon="#android:drawable/ic_menu_search"
android:actionLayout="#layout/search_menu"
android:showAsAction="collapseActionView|ifRoom"
android:title="#string/search_title"/>
</menu>
Now I want to add OnClickListener on _search_btn_ So I did that likewise :
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
searchButton = (Button) menu.findItem(R.id.search_btn);
searchButton.setOnClickListener(new OnClickListener() { // SEE HERE I'M GETTING NullPointerException
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, ((EditText) findViewById(R.id.search_et)).getText().toString(), Toast.LENGTH_LONG).show();
}
});
return true;
}
but I'm getting my NullPointerException on above mentioned line. How can I add ClickListener to that button???

You're using the wrong id. Use the id for your menu item. You can use getActionView on the MenuItem to get the layout.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
MenuItem searchItem = menu.findItem(R.id.search_view);
Button searchButton = searchItem.getActionView().findViewById(R.id.search_btn);
searchButton.setOnClickListener(new OnClickListener() { // SEE HERE I'M GETTING NullPointerException
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, ((EditText) findViewById(R.id.search_et)).getText().toString(), Toast.LENGTH_LONG).show();
}
});
return true;
}

please try on onOptionsItemSelected method.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.search_view:
//write your code here
return true;
default:
return super.onOptionsItemSelected(item);
}
}

Well your not getting a reference to your button. i.e in searchButton = (Button) menu.findItem(R.id.search_btn); you searchButton is null.
Your using a wrong id.

Android onCreateOptionMenu not being called

I am implementing an Android Activity from which other Activities will be derived from. So basically I have this setup of an InventoryActivity and its parent class, ListActivity:
public class MyListActivity extends Activity {
protected Context mContext;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mContext = this.getBaseContext();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options, menu);
Log.d("Creating options menu", "True");
return true;
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
Log.d("Preparing options menu", "True");
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.save:
return(true);
case R.id.revert:
return(true);
}
return(super.onOptionsItemSelected(item));
}
}
public class InventoryActivity extends MyListActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.inventory);
}
}
And I also have this in options.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/card_list_save"
android:icon="#drawable/ic_menu_save"
android:title="Save"/>
<item android:id="#+id/card_list_revert"
android:icon="#drawable/ic_menu_revert"
android:title="Revert" />
</menu>
If necessary, this is my layout for inventory.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="#+id/callSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Search"/>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="#+id/inventory"/>
</ScrollView>
</LinearLayout>
However, when I press the menu button, nothing happens. The Log messages in the onCreateOptionsMenu method does not appear. Instead all I can see is the following:
02-04 11:36:58.313: W/KeyCharacterMap(31464): No keyboard for id 0
02-04 11:36:58.313: W/KeyCharacterMap(31464): Using default keymap: /system/usr/keychars/qwerty.kcm.bin
But what baffles me the most is that this code works in other Activities, such as my launcher Activity. But by the concept of object oriented programming, the InventoryActivity should call the overriding methods in the MyListActivity. I am completely stuck and I need help.

ListActivity is already a class in the Android SDK. My guess is that you're importing android.app.ListActivity, and not your package.

Hmm...don't know why but removing the onCreate method in MyListActivity fixed the problem. So the class now looks like this:
public class MyListActivity extends Activity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options, menu);
Log.d("Creating options menu", "True");
return true;
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
Log.d("Preparing options menu", "True");
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.save:
return(true);
case R.id.revert:
return(true);
}
return(super.onOptionsItemSelected(item));
}
}
