I'm trying to get statusBar height inside onCreate but the methods that I found here need some view already draw to get it's size and then calculate statusBar height.
Since I'm on onCreate, there's nothing draw yet for me to get it's size
Someone can help me here?
root = (ViewGroup)findViewById(R.id.root); root.post(new Runnable() { public void run(){ Rect rect = new Rect(); Window win = getWindow(); win.getDecorView().getWindowVisibleDisplayFrame(rect); int statusHeight = rect.top; int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop(); int titleHeight = contentViewTop - statusHeight; Log.e("dimen", "title = " + titleHeight + " status bar = " + statusHeight); } }); Use a global layout listener
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // inflate your main layout here (use RelativeLayout or whatever your root ViewGroup type is LinearLayout mainLayout = (LinearLayout ) this.getLayoutInflater().inflate(R.layout.main, null); // set a global layout listener which will be called when the layout pass is completed and the view is drawn mainLayout.getViewTreeObserver().addOnGlobalLayoutListener( new ViewTreeObserver.OnGlobalLayoutListener() { public void onGlobalLayout() { // measure your views here } } ); setContentView(mainLayout); [EDIT]
To do this only once:
ViewTreeObserver observer = mainLayout.getViewTreeObserver(); observer.addOnGlobalLayoutListener (new OnGlobalLayoutListener () { @Override public void onGlobalLayout() { // measure your views here mainLayout.getViewTreeObserver().removeGlobalOnLayoutListener(this); } });
