Get the height of the android Status Bar

In Android development, you often need to know the screen height, width, Status Bar, and Title Bar Height.

Width and height

WindowManager windowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);Display display = windowManager.getDefaultDisplay();Point point = new Point();display.getSize(point);SCREEN_WIDTH = point.x;SCREEN_HEIGHT = point.y;System.out.println("SCREEN_WIDTH = " + SCREEN_WIDTH);System.out.println("SCREEN_HEIGHT = " + SCREEN_HEIGHT);

Status Bar Height

If you are working on Rom, you can use the following methods:

int id = com.android.internal.R.dimen.status_bar_height;STATUS_BAR_HEIGHT = (int) getResources().getDimension(id);

The above method only applies to Rom, because the id value has been assigned during compilation, such as COM. android. internal. r. dimen. status_bar_height = 123; the actual code is like this.

int id = 123;STATUS_BAR_HEIGHT = (int) getResources().getDimension(id);

Another method is the improvement of the above method. The Java reflection principle is used to obtain the height.

int id = 0;try {Class<?> cls = Class.forName("com.android.internal.R$dimen");Field field = cls.getField("status_bar_height");id = field.getInt(cls);} catch (ClassNotFoundException e) {e.printStackTrace();} catch (NoSuchFieldException e) {e.printStackTrace();} catch (IllegalArgumentException e) {e.printStackTrace();} catch (IllegalAccessException e) {e.printStackTrace);}
