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

有一个非常简单的答案，没有通过上下文

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

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

注:如果你想要高度包括导航条，使用下面的方法

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;
    }

其他回答

@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
  public static double getHeight() {
    DisplayMetrics displayMetrics = new DisplayMetrics();
    WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();
    display.getRealMetrics(displayMetrics);

    //int height = displayMetrics.heightPixels;
    //int width = displayMetrics.widthPixels;
    return displayMetrics.heightPixels;
  }

使用这种方法你可以得到屏幕高度。如果你想要宽度改变displayMetrics。hightpixels到displayMetrics.widthPixels。

它还包括所需的api构建版本。

似乎所有这些答案都不适合我的Galaxy M51和Android 11。在做了一些研究之后，我发现了这个代码:

WindowMetrics windowmetrics = MainActivity.getWindowManager().getCurrentWindowMetrics();
Rect rect = windowmetrics.getBounds();
int width = rect.right;
int height =rect.bottom;

显示我的真实设备分辨率为1080x2400，其余只返回810x1800。

我使用下面的代码来获取屏幕尺寸

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

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(); 
}

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