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。我使用下面的代码:

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

问题是当软导航条存在时，返回的高度=实际高度-导航条高度。我想要得到总价值

注意:我使用Android SDK 13 (v 3.2)。

Answer 1

检查这个，它可能会有所帮助:

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);

源:

http://developer.android.com/reference/android/view/Display.html getRealSize (android.graphics.Point)

Answer 3

你可以使用DisplayMetrics。这个类保存关于屏幕的信息，比如它的大小，密度，字体缩放。例如

getResources().getDisplayMetrics().widthPixels

返回

The absolute width of the display in pixels.

检索高度

getResources().getDisplayMetrics().heightPixels

Answer 4

在你的类的onCreate方法中写下这段代码，你将得到屏幕的实际宽度和高度:

Display mDisplay = this.getWindowManager().getDefaultDisplay();

    final int width = mDisplay.getWidth();
    final int height = mDisplay.getHeight();
    System.out.println("width " + width + "  height " + height);
