Can I listen to when the Navigation drawer is opened or closed (e.g: listener like button onclick)?
Yeah there are four abstract methods that you can use as listeners
public abstract void onDrawerClosed (View drawerView)
public abstract void onDrawerOpened (View drawerView)
public abstract void onDrawerSlide (View drawerView, float slideOffset)
public abstract void onDrawerStateChanged (int newState)
can be used like this
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
// Do whatever you want here
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
// Do whatever you want here
}
};
mDrawerLayout.addDrawerListener(mDrawerToggle);
copied from http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.DrawerListener.html
UPDATE
setDrawerListener
method was deprecated in API level 24.1.0. so use addDrawerListener()
You can know it by using this piece of code by using ActionBarDrawerToggle as:
ActionBarDrawerToggle drawerToggle = new android.support.v7.app.ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close) {
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
mDrawer.setDrawerListener(drawerToggle);
There are 4 abstract methods provided in the abstract inner class 'DrawerListener' of 'DrawerLayout' Class
public abstract void onDrawerClosed (View drawerView)
public abstract void onDrawerOpened (View drawerView)
public abstract void onDrawerSlide (View drawerView, float slideOffset)
public abstract void onDrawerStateChanged (int newState)
Useful Example :
((DrawerLayout) findViewById(R.id.drawer_layout)).addDrawerListener(new DrawerLayout.DrawerListener() {
@Override
public void onDrawerSlide(@NonNull View drawerView, float slideOffset) {
// Whatever you want
}
@Override
public void onDrawerOpened(@NonNull View drawerView) {
// Whatever you want
}
@Override
public void onDrawerClosed(@NonNull View drawerView) {
// Whatever you want
}
@Override
public void onDrawerStateChanged(int newState) {
// Whatever you want
}
});
