在Android中获取屏幕宽度和高度

我如何获得屏幕的宽度和高度，并使用这个值在:

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

当前回答

public class DisplayInfo {
    int screen_height=0, screen_width=0;
    WindowManager wm;
    DisplayMetrics displaymetrics;

    DisplayInfo(Context context) {
        getdisplayheightWidth(context);
    }

    void getdisplayheightWidth(Context context) {
        wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
        displaymetrics = new DisplayMetrics();
        wm.getDefaultDisplay().getMetrics(displaymetrics);
        screen_height = displaymetrics.heightPixels;
        screen_width = displaymetrics.widthPixels;
    }

    public int getScreen_height() {
        return screen_height;
    }

    public int getScreen_width() {
        return screen_width;
    }
}

我发现weigan的答案最好的一个在这一页，这里是如何在Xamarin使用它。Android:

public int GetScreenWidth()
{
    return Resources.System.DisplayMetrics.WidthPixels;
}

public int GetScreenHeight()
{
    return Resources.System.DisplayMetrics.HeightPixels;
}

只是通过parag和SpK更新答案，使其与当前SDK的向后兼容性保持一致:

int Measuredwidth = 0;  
int Measuredheight = 0;  
Point size = new Point();
WindowManager w = getWindowManager();

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)    {
    w.getDefaultDisplay().getSize(size);
    Measuredwidth = size.x;
    Measuredheight = size.y; 
}else{
    Display d = w.getDefaultDisplay(); 
    Measuredwidth = d.getWidth(); 
    Measuredheight = d.getHeight(); 
}

public class DisplayInfo {
    int screen_height=0, screen_width=0;
    WindowManager wm;
    DisplayMetrics displaymetrics;

    DisplayInfo(Context context) {
        getdisplayheightWidth(context);
    }

    void getdisplayheightWidth(Context context) {
        wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
        displaymetrics = new DisplayMetrics();
        wm.getDefaultDisplay().getMetrics(displaymetrics);
        screen_height = displaymetrics.heightPixels;
        screen_width = displaymetrics.widthPixels;
    }

    public int getScreen_height() {
        return screen_height;
    }

    public int getScreen_width() {
        return screen_width;
    }
}

我使用下面的代码来获取屏幕尺寸

getWindow().getDecorView().getWidth()
getWindow().getDecorView().getHeight()

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