Disable Back Button in Android Programmatically


Do you want to disable the Back button functionality for your android app, i.e. you do not want any action to be performed when the back button is being pressed on the device.

Well, here is how you can achieve this programmatically in Java code.

All you need to do is implement the onBackPressed function. Override this function but do not put any code in it. This will result in no action when the back button is pressed.

As simple as that !! ..

@Override
public void onBackPressed() {
 // Simply Do noting!
}
package com.code2care.backButtonExample;

public class BackButtonExample extends Activity {
	private TextView textview;
	private SwipeDetector sd;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_swipe_demo);

	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.swipe_demo, menu);
		return true;
	}
	
	@Override
	public boolean onTouchEvent(MotionEvent me) {
		return sd.onTouch(null, me);
	}
	
	@Override
	public boolean dispatchTouchEvent(MotionEvent ev) {
		super.dispatchTouchEvent(ev);
		return sd.onTouchEvent(ev);
	}
	
	@Override
	public void onBackPressed() {
	// Simply Do noting!
	}
}

}
