Android Navigational Drawer activate w/ button

Question

since i am quite new to Android i am trying to create a Navigational Drawer that gets activated when pressing a button. I checked several tutorials like this one but in all of them the drawer gets activated when an Actionbar button is pressed. One more thing. My activity consists of 3 buttons and an image so i use RelativeLayout, how can i add a FrameLayout to RelativeLayout? Should i change it?

Can someone work something out so i can get the general idea? Thank you in advance for your time!

Answer 1

In the XML element (e.g. Button, or TextView) put:

android:onClick="onBtnClick"

In the linked Activity add the method:

public void onBtnClick(View view) {
    //open the drawer as a menu
    View mFragmentContainerView = findViewById(R.id.navigation_drawer);
    DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerLayout.openDrawer(mFragmentContainerView);
}

You can simply drag a FrameLayout into a RelativeLayout, so I do not understand your issue there.
