Answer 1

Bu yeni ve eski cihazlarını destekler: tüm cihazlar için Ekran Boyutu almak için

private static Point getDisplaySize(final Display display) { 
    final Point point = new Point(); 
    try { 
     display.getSize(point); 
    } catch (java.lang.NoSuchMethodError ignore) { // Older device 
     point.x = display.getWidth(); 
     point.y = display.getHeight(); 
    } 
    return point; 
} 

Answer 2

deneyin yerine kullanın:

Display display = getWindowManager().getDefaultDisplay(); 

Bu kodda herhangi bir sorun görmüyorum ...

Answer 3

Bunu deneyin, benim için çalışıyor. Geç partiye dilerim ama android sdk 13 veya üzeri kullandığınızdan emin olun

getWindowManager().getDefaultDisplay().getWidth(); 

Answer 4

üzgünüm.

Answer 5

Yöntemi:

private static Point getDisplaySize(final Display display) { 
Point point = new Point(); 
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2){ //API LEVEL 13 
    display.getSize(point); 
}else{  
    point.x = display.getWidth(); 
    point.y = display.getHeight(); 
} 
return point; 
    } 

gettin Boyutu:

İşte

WindowManager wm = ((WindowManager)context.getSystemService(context.WINDOW_SERVICE)); 
    Display display = wm.getDefaultDisplay(); 
    Point myPoint = getDisplaySize(display); 
    Log.i("***Size X::", String.valueOf(myPoint.x)); 
    Log.i("***Size Y::", String.valueOf(myPoint.y)); 

Answer 6

yarar yöntemidir Kullanabileceğiniz:

public static int getWidth(Context context) { 
     WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); 
     Display display = windowManager.getDefaultDisplay(); 
     Point size = new Point(); 
     int width; 
     if (Build.VERSION.SDK_INT >= 13) { 
      display.getSize(size); 
      width = size.x; 

     } else { 
      width = display.getWidth(); 
     } 
     return width; 
    } 

Answer 7

Bu sürüm de API < 4 için çalışır:

@SuppressWarnings("deprecation") 
@TargetApi(VERSION_CODES.HONEYCOMB_MR2) 
public static Point getSize(Display display) { 
    Point point = new Point(); 
    if (sdkInt() >= VERSION_CODES.HONEYCOMB_MR2) { 
     display.getSize(point); 
    } else { 
     point.set(display.getWidth(), display.getHeight()); 
    } 
    return point; 
} 

@SuppressWarnings("deprecation") 
public static int sdkInt() { 
    return Integer.parseInt(VERSION.SDK); 
}
