的getSize（）给我的错误

当我实现的getSize（）给我的错误

WindowManager wm = ((WindowManager)context.getSystemService(context.WINDOW_SERVICE)); 
Display display = wm.getDefaultDisplay(); 
m_nDisplayWidth = display.getWidth(); 
m_nDisplayHeight = display.getHeight();

我可以运行良好，但是当我执行的getSize我得到runtimeError

Point size = new Point(); 
display.getSize(size); //Error right here 
m_nDisplayWidth = size.x; 
m_nDisplayHeight = size.y;

的logcat：

这支持新旧设备：

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; 
}

getWidth和getHeight自getSize方法到达后不再使用，但仅适用于api级别13和更高版本，因此无法使用旧设备的弃用方法。你的答案+1。谢谢 – Zoombie 2012-10-16 06:23:25

尝试改用：

Display display = getWindowManager().getDefaultDisplay();

没有这一点，我没有看到在这个代码中的任何问题...

试试这个，它适用于我。

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

的getWidth（）已过时http://developer.android.com/reference/android/view/Display.html#getWidth（） – pahan 2013-03-29 10:26:30

对不起，我迟到了派对，但请确保您使用的是android sdk 13或更高版本。

如果你想让你的应用在老版本上运行，就像大多数手机一样？ – 2012-04-07 19:46:01

方法得到显示屏尺寸为所有设备：

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; 
    }

刚开尺寸：

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));

我认为你缺少display.getSize（） – Lukos 2013-06-17 14:53:49

非常感谢你Lukos！我编辑了我的回复！ =） – Jorgesys 2013-06-17 16:35:58

Build.VERSION.SDK_INT需要Android API级别4或更高。 – Tamara 2013-09-13 07:20:30

这里是实用方法，你可以利用：

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; 
    }

该版本适用于API < 4，太：

@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); 
}
