Data Binding in an Activity with a MapFragment

I would like to use Data Binding Library in one of my projects but I am getting an error in the activity who has a MapFragment. Not using data binding librery the code works perfectly

My xml main_activity file:

<layout 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">

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v7.widget.Toolbar
android:id="@+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.project.activities.MainActivity" />

</RelativeLayout>

</layout>


And the baseActivity related

public abstract class BaseActivity extends AppCompatActivity {

private ActivityMainBinding binding;
private Toolbar toolbar;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = DataBindingUtil.setContentView(this, getContentView());
setContentView(getContentView());//Crashes
getPresenter();
configureToolbar();
Log.d(Constans.LOG_TAG,"On create");
}

private void configureToolbar() {

toolbar = binding.myToolbar;
if (toolbar != null) {
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

}


@Override
protected void onStop() {
super.onStop();
Log.d(Constans.LOG_TAG,"On Stop");

}

@Override
protected void onResume() {
super.onResume();
Log.d(Constans.LOG_TAG,"On resume");

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
return super.onCreateOptionsMenu(menu);


}

protected abstract int getContentView();
protected abstract void getPresenter();

}


And the error I get is :

The error itself is on onCreate(Bundle savedInstanceState) method on


setContentView(getContentView());


What I am doing wrong?

Answer

remove this line

setContentView(getContentView());//Crashes

and pass your layout resource to

binding = DataBindingUtil.setContentView(this, R.id.main_activity);
