you must attach toolbar in ActionBarDrawerToggle
mDrawerToogle = new ActionBarDrawerToggle(this, drawer,toolbar,R.string.navigation_drawer_open, R.string.navigation_drawer_close);
bar.setHomeButtonEnabled(true);
bar.setDisplayHomeAsUpEnabled(true);
mDrawerToogle.syncState();
drawer.setDrawerListener(mDrawerToogle);

you have to handle this action by yourself
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
drawerLayout.openDrawer(Gravity.LEFT);
return true;
}
return super.onOptionsItemSelected(item);
}
also syncState() call should be placed in onPostCreate or even in onResume
btw. your empty constructor should at least call super();

Make the layout below button

In one of my fragment class, it has two buttons (A and B) on top, used to switch to another fragment when clicked using viewPager.
When buttonA is clicked, it should switch to page A and so on.
When I click button A, how can I make the text in A show below the two buttons?
fragment_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

public class MenuFragment extends BaseFragment {
#Override

Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_menu, container, false);
final ViewPager viewPager = (ViewPager) v.findViewById(R.id.pager);
viewPager.setAdapter(new ViewPagerAdapter(getActivity().getFragmentManager()));
Button btnA = (Button) v.findViewById(R.id.buttonA);
Button btnB = (Button) v.findViewById(R.id.buttonB);
btnA.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
viewPager.setCurrentItem(0, true);
}
});
btnB.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
viewPager.setCurrentItem(1, true);
}
});
return v;
}
}
ViewPagerAdapter
public class ViewPagerAdapter extends FragmentPagerAdapter {
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position)

case 0:

}
return null;
}

Output

try with below code.hope it is helpful for you ;)
P.S. You just need to set button style as you want :)
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.viewpager.widget.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_above="#id/llButton"
android:layout_height="match_parent" />
<LinearLayout
android:id="#+id/llButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_marginBottom="10dp">
<Button
android:id="#+id/buttonA"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:padding="15dp"
android:text="ButtonA"
android:textSize="12sp" />
<Button
android:id="#+id/buttonB"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginTop="10dp"
android:layout_marginRight="15dp"
android:backgroundTint="#color/colorAccent"
android:padding="15dp"
android:text="ButtonB"
android:textSize="12sp" />
</LinearLayout>
</RelativeLayout>

Since you are using Relative Layout you can add layout_below
<androidx.viewpager.widget.ViewPager
android:layout_below="#id/buttonB"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />

you are doing it wrong, You cannot align a button to itself. That's why your buttons are not working properly. In your button B do this:
android:layout_toRightOf="#+id/buttonA"
instead of this:
android:layout_toRightOf="#+id/buttonB"
And to your viewPager add "android:layout_below:"
<androidx.viewpager.widget.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/buttonA" />

You have to set your layout like this....
[I think you want something like this 2 button fisrt and then viewpager for change the content ][1]

for Android version 6 error, but at lower Android working properly.
Where is the problem?

You can try two approaches:
"Just downgrade your - targetSdkVersion to 22 It works for all
versions" - This works fine if you have not launched your app with
targetSdkVersion 23 yet.
If you already have launched your app with targetSdkVersion 23 then,
instead of adding compile 'com.github.traex.rippleeffect:library:1.3'
in dependancies, Download the project by clicking on link -
https://codeload.github.com/traex/RippleEffect/zip/master
Get library from that and use that in your app. It's probably gonna work :)

Activity is hidden by fragment, it is not useable

i have builded an app that works perfectly on android with api higer than 21. The problem is that this instruction of my code:
mFragmentTransaction.replace(R.id.content_frame, new TabFragment()).commit();
Works in different way on API less then 21.
On Api less then 21 the new fragment hide the previus activity, so that i can't click on my Floating Action Button.
Here are two images that explain in abetter way my problem.
API HIGER THAN 21
API LESS THAN 21
So my question is: How can i have the same result in API less then 21 that i have on API Higer then 21?
Here is the affected part of the Main Activity Code:
public class MainActivity extends AppCompatActivity {
public static AppDataBase appDataBase;
public static UserDataBase userDataBase;
static FragmentManager mFragmentManager;
static FragmentTransaction mFragmentTransaction;
private DrawerLayout myDrawerLayout;
final String TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE = "Add a console!";
TextView currentConsole;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
appDataBase = new AppDataBase(this);
userDataBase = new UserDataBase(this);
myDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
currentConsole = (TextView) findViewById(R.id.txt_Mainactvt_currentConsole);
currentConsole.setText(TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE);
tabLayoutManagement();
floatingActionButtonManagement();
leftDrawerMenuManagement();
rigthDrawerMenuManagement();
populateMyConsole();
}
void tabLayoutManagement() {
mFragmentManager = getSupportFragmentManager();
mFragmentTransaction = mFragmentManager.beginTransaction();
mFragmentTransaction.replace(R.id.content_frame, new TabFragment()).commit();
}
// Floating Action Button
private void floatingActionButtonManagement() {
FloatingActionButton fab_addGame = (FloatingActionButton)findViewById(R.id.fab_AddGame);
fab_addGame.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
/*
The currentConsole TextView is used to show at the user wich console is selected.
We use it to have a strng that conteins the selected console.
Call the method that manage the click event of the FloatingActionButton. We pass the console name.
*/
String currentConsoleName = currentConsole.getText().toString();
floatingActionButtonClickEvent(currentConsoleName);
}
});
}
private void floatingActionButtonClickEvent(String currentConsoleName) {
/*
Check if user have added a console. If he did start a menu for adding games, else start an
error message
*/
if (!currentConsoleName.equals(TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE)) {
popUpViewAddGameBuild(currentConsoleName);
}
else
mySimpleAlertDialogMethod("Attention!", "Before you enter game, you must enter a console.", true, true);
}
private void popUpViewAddGameBuild(String currentConsoleName) {
/*
Build the view that show the menu for adding games.
*/
LayoutInflater inflater = this.getLayoutInflater();
View popupView = inflater.inflate(R.layout.popupview_addgame, null);
PopupWindow popupWindow = new PopupWindow(
popupView,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT);
popupWindow.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);
popupWindow.setFocusable(true);
popupWindow.showAtLocation(popupView, 0, 0, 0);
}
Here is the TabLayout Class:
public class TabFragment extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View x = inflater.inflate(R.layout.tab_layout, null);
tabLayout = (TabLayout) x.findViewById(R.id.tabs);
viewPager = (ViewPager) x.findViewById(R.id.viewpager);
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
tabLayout.post(new Runnable() {
#Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
return x;
}
public class MyAdapter extends FragmentPagerAdapter {
public int position;
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0 :
return new DesireFragment();
case 1 :
return new BuyedFragment();
case 2 :
return new StartedFragment();
case 3 :
return new FinishedFragment();
case 4 :
return new AllTrophiesFragment();
}
return null;
}
#Override
public int getCount() {
return 5;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position){
case 0 :
return "Desire";
case 1 :
return "Buyed";
case 2 :
return "Started";
case 3 :
return "Finished";
case 4 :
return "AllTrophies";
}
return null;
}
}
}
There is the layout of the MainActivity:

And here is the layout code of the TabLayout:
<?xml version="1.0" encoding="utf-8"?>

<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>

You replace the content of your FrameLayout with an Fragment. this leads to your strange result.
Add a Layout to your Framelayout instead and use it as your FragmentContainer:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:backgroundTint="#color/colorPrimary"
app:borderWidth="0dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content_frame"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="30dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="#+id/txt_Mainactvt_currentConsole"
android:layout_gravity="center_horizontal|top"
android:layout_marginTop="50dp"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab_AddGame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="17dp"
android:layout_marginRight="17dp"
android:src="#drawable/ic_mode_edit_white_24dp"
android:layout_gravity="bottom|right"
android:background="#color/colorPrimary" />
</FrameLayout>

Try to place your FrameLayout with this button to the end of layout
