Get screen width and height in Android

Question

How can I get the screen width and height and use this value in:

@Override protected void onMeasure(int widthSpecId, int heightSpecId) {     Log.e(TAG, "onMeasure" + widthSpecId);     setMeasuredDimension(SCREEN_WIDTH, SCREEN_HEIGHT -          game.findViewById(R.id.flag).getHeight()); } 

Answer 1

Using this code, you can get the runtime display's width & height:

DisplayMetrics displayMetrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(displayMetrics); int height = displayMetrics.heightPixels; int width = displayMetrics.widthPixels;

In a view you need to do something like this:

((Activity) getContext()).getWindowManager()                          .getDefaultDisplay()                          .getMetrics(displayMetrics);

In some scenarios, where devices have a navigation bar, you have to check at runtime:

public boolean showNavigationBar(Resources resources) {     int id = resources.getIdentifier("config_showNavigationBar", "bool", "android");     return id > 0 && resources.getBoolean(id); } 

If the device has a navigation bar, then count its height:

private int getNavigationBarHeight() {     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {         DisplayMetrics metrics = new DisplayMetrics();         getWindowManager().getDefaultDisplay().getMetrics(metrics);         int usableHeight = metrics.heightPixels;         getWindowManager().getDefaultDisplay().getRealMetrics(metrics);         int realHeight = metrics.heightPixels;         if (realHeight > usableHeight)             return realHeight - usableHeight;         else             return 0;     }     return 0; } 

So the final height of the device is:

int height = displayMetrics.heightPixels + getNavigationBarHeight();

There is a very simple answer and without pass context

public static int getScreenWidth() {     return Resources.getSystem().getDisplayMetrics().widthPixels; }  public static int getScreenHeight() {     return Resources.getSystem().getDisplayMetrics().heightPixels; } 

Note: if you want the height include navigation bar, use method below

WindowManager windowManager =         (WindowManager) BaseApplication.getApplication().getSystemService(Context.WINDOW_SERVICE);     final Display display = windowManager.getDefaultDisplay();     Point outPoint = new Point();     if (Build.VERSION.SDK_INT >= 19) {         // include navigation bar         display.getRealSize(outPoint);     } else {         // exclude navigation bar         display.getSize(outPoint);     }     if (outPoint.y > outPoint.x) {         mRealSizeHeight = outPoint.y;         mRealSizeWidth = outPoint.x;     } else {         mRealSizeHeight = outPoint.x;         mRealSizeWidth = outPoint.y;     }
