屏幕高度 - Android

Question

在Android应用程序中，我想知道屏幕的高度和宽度。我正在使用以下代码：

Point size = new Point(); 
display.getSize(size); 
screenWidth = size.x; 
screenHeight = size.y; 

问题是，当软导航栏存在时，返回的高度=实际高度 - 导航栏高度。 我想获得总价值。

注意：我正在使用Android SDK 13（v 3.2）。

Answer 1

检查这一点，它可以帮助：

FrameLayout root = (FrameLayout) findViewById(R.id.root); 
    root.post(new Runnable() { 
     public void run() { 
      Rect rect = new Rect(); 
      Window win = getWindow(); // Get the Window 
      win.getDecorView().getWindowVisibleDisplayFrame(rect); 
      // Get the height of Status Bar 
      int statusBarHeight = rect.top; 
      // Get the height occupied by the decoration contents 
      int contentViewTop = win.findViewById(Window.ID_ANDROID_CONTENT).getTop(); 
      // Calculate titleBarHeight by deducting statusBarHeight from contentViewTop 
      int titleBarHeight = contentViewTop - statusBarHeight; 

      // By now we got the height of titleBar & statusBar , Now lets get the screen size 
      int screenHeight = dm.heightPixels; 

      // Now calculate the height that our layout can be set If you know that your application doesn't have statusBar added, then don't add here also. 
      //Same applies to application bar also 
      int layoutHeight = screenHeight - (titleBarHeight + statusBarHeight); 

     } 
    }); 

Answer 2

您可以使用 display.getRealSize(size);代替display.getSize(size);

Answer 3

可以使用DisplayMetrics。这个类拥有关于屏幕的信息，例如它的大小，密度，字体缩放。例如

getResources().getDisplayMetrics().widthPixels 

回报

The absolute width of the display in pixels. 

检索高度

getResources().getDisplayMetrics().heightPixels 

Answer 4

在类的onCreate方法写下这段代码，你会得到屏幕的实际宽度和高度：

显示mDisplay = this.getWindowManager（）。getDefaultDisplay（）;

final int width = mDisplay.getWidth(); 

    final int height = mDisplay.getHeight(); 

    System.out.println("width " + width + " height " + height);
