android – How to get the available Screen Height minus Navigation Bar in HoneyComb?

Is there a way the measure the hight of the navigation bar at the bottom in pixels?

How to&Answers:

By the way… for anyone else like me who stumbled upon this question looking for the actual number, it’s 48 pixels (on the Motorola Xoom, at least). This was based upon the debug output of this (admittedly crude) test Activity, combined with a Theme with no title bar (e.g., @android:style/Theme.NoTitleBar) and a single-View LinearLayout with both height and width set to “match_parent” (e.g., the one created when creating a new Android app) :

package com.sample.layouttest;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnLayoutChangeListener;

public class Main extends Activity implements OnLayoutChangeListener {

    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        View newView = getLayoutInflater().inflate(R.layout.main, null);

    public void onLayoutChange(View view, int left, int top, int right,
            int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
        Log.d("LayoutTest","left="+left+", top="+top+", right="+right+", bottom="+bottom);

On a Motorola Xoom running Android 3.1 (as well as a Samsung Galaxy 10.1V running 3.0), the output from the onLayoutChange method when entering portrait mode is :

05-24 15:11:43.047: DEBUG/LayoutTest(8658): left=0, top=0, right=800, bottom=1232

and when entering landscape :

05-24 15:13:18.837: DEBUG/LayoutTest(8658): left=0, top=0, right=1280, bottom=752


meanwhile i found the solution. there is a new OnLayoutChangeListener event in honycomb wich allows you wait for the layout to be finished and then measure the size of your layout instead of the screensize.
