Height of status bar in Android

asked Aug 4, 2010 by hpique

What's the height of the status bar in Android? Is it always the same?

From my measurements it seems that it's 25dp, but I'm not sure if it has the same height on all platforms.

(I want to know this to properly implement a fade transition from an activity that doesn't have status bar to one that does)

Try this:

    Rect rect = new Rect();
    Window win = this.getWindow();
    win.getDecorView().getWindowVisibleDisplayFrame(rect);
    int statusBarHeight = rect.top;
    int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop();
    int titleBarHeight = contentViewTop - statusBarHeight;
    Log.d("ID-ANDROID-CONTENT", "titleBarHeight = " + titleBarHeight );

it didn't work for me in the onCreate method for the activity, but did when I put it in an onClickListener and gave me a measurement of 25

If you know exactly the size VS height

like

for example in a device with 320 X 480 screen size the status bar height is 25px, for a device with 480 x 800 the status bar height must be 38px

then you can just get the width of your view / the screen size you can just use an if else statement to get the height of status bar

240x320 - 20px

320x480 - 25px

480x800+ - 38px

this question was answered before... Height of statusbar?

Update::

Current method:

ok, the height of the status bar depends on the screen size, for example in a device with 240 X 320 screen size the status bar height is 20px, for a device with 320 X 480 screen size the status bar height is 25px, for a device with 480 x 800 the status bar height must be 38px

so i recommend to use this script to get the status bar height

Rect rectangle = new Rect();
Window window = getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rectangle);
int statusBarHeight = rectangle.top;
int contentViewTop = 
    window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
int titleBarHeight= contentViewTop - statusBarHeight;

   Log.i("*** Elenasys :: ", "StatusBar Height= " + statusBarHeight + " , TitleBar Height = " + titleBarHeight); 

(old Method) to get the Height of the status bar on the onCreate() method of your Activity, use this method:

public int getStatusBarHeight() { 
      int result = 0;
      int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
      if (resourceId > 0) {
          result = getResources().getDimensionPixelSize(resourceId);
      } 
      return result;
}

I have the same problem of having to get the status bar height in an onCreate. This works for me.

private static final int LOW_DPI_STATUS_BAR_HEIGHT = 19;

private static final int MEDIUM_DPI_STATUS_BAR_HEIGHT = 25;

private static final int HIGH_DPI_STATUS_BAR_HEIGHT = 38;

Inside the onCreate:

DisplayMetrics displayMetrics = new DisplayMetrics();
((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getMetrics(displayMetrics);

int statusBarHeight;

switch (displayMetrics.densityDpi) {
    case DisplayMetrics.DENSITY_HIGH:
        statusBarHeight = HIGH_DPI_STATUS_BAR_HEIGHT;
        break;
    case DisplayMetrics.DENSITY_MEDIUM:
        statusBarHeight = MEDIUM_DPI_STATUS_BAR_HEIGHT;
        break;
    case DisplayMetrics.DENSITY_LOW:
        statusBarHeight = LOW_DPI_STATUS_BAR_HEIGHT;
        break;
    default:
        statusBarHeight = MEDIUM_DPI_STATUS_BAR_HEIGHT;
}

On MDPI devices, the status bar is 25px. We can use this as the base and multiply it by the density (rounded up) to get the status bar height on any device:

int statusBarHeight = Math.ceil(25 * context.getResources().getDisplayMetrics().density);

For reference: ldpi=.75, mdpi=1, hdpi=1.5, xhdpi=2

Yes when i try it with View it provides the result of 25px. Here is the whole code :

public class SpinActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LinearLayout lySpin = new LinearLayout(this);
        lySpin.setOrientation(LinearLayout.VERTICAL);       
        lySpin.post(new Runnable()
        {
            public void run()
            {
                Rect rect = new Rect();
                Window window = getWindow();
                window.getDecorView().getWindowVisibleDisplayFrame(rect);
                int statusBarHeight = rect.top;
                int contentViewTop = 
                    window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
                int titleBarHeight = contentViewTop - statusBarHeight;
                System.out.println("TitleBarHeight: " + titleBarHeight 
                    + ", StatusBarHeight: " + statusBarHeight);
            }
        }
    }
}

To solve this, I used a combination approach. This is necessary as on tablets the system bar already subtracts it's pixels when display.getHeight() is called. So I first check if a system bar is present, and then Ben Claytons approach, which works fine on phones.

public int getStatusBarHeight() {
    int statusBarHeight = 0;

    if (!hasOnScreenSystemBar()) {
        int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
            statusBarHeight = getResources().getDimensionPixelSize(resourceId);
        }
    }

    return statusBarHeight;
}

private boolean hasOnScreenSystemBar() {
    Display display = getWindowManager().getDefaultDisplay();
    int rawDisplayHeight = 0;
    try {
        Method getRawHeight = Display.class.getMethod("getRawHeight");
        rawDisplayHeight = (Integer) getRawHeight.invoke(display);
    } catch (Exception ex) {
    }

    int UIRequestedHeight = display.getHeight();

    return rawDisplayHeight - UIRequestedHeight > 0;
}

Out of all the code samples I've used to get the height of the status bar, the only one that actually appears to work in the onCreate method of an Activity is this:

public int getStatusBarHeight() {
    int result = 0;
    int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}

Apparently the actual height of the status bar is kept as an Android resource. The above code can be added to a ContextWrapper class (e.g. an Activity).

this also work with the refrence link

public int getStatusBarHeight() {
  int result = 0;
  int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
  if (resourceId > 0) {
      result = getResources().getDimensionPixelSize(resourceId);
  }
  return result;
}
