Android获取状态栏和标题栏的高度

来源：互联网发布：陕西省大数据集团公司编辑：程序博客网时间：2024/05/29 04:37

1.获取状态栏高度：

decorView是window中的最顶层view，可以从window中获取到decorView，然后decorView有个getWindowVisibleDisplayFrame方法可以获取到程序显示的区域，包括标题栏，但不包括状态栏。
于是，我们就可以算出状态栏的高度了。

01.Rect frame = new Rect();
02.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
03.int statusBarHeight = frame.top;
Rect frame = new Rect();
getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
int statusBarHeight = frame.top;

2.获取标题栏高度：

getWindow().findViewById(Window.ID_ANDROID_CONTENT)这个方法获取到的view就是程序不包括标题栏的部分，然后就可以知道标题栏的高度了。

01.int contentTop = getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();
02.//statusBarHeight是上面所求的状态栏的高度
03.int titleBarHeight = contentTop - statusBarHeight
int contentTop = getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();
//statusBarHeight是上面所求的状态栏的高度
int titleBarHeight = contentTop - statusBarHeight

例子代码：

02.import android.app.Activity;
03.import android.graphics.Rect;
04.import android.os.Bundle;
05.import android.util.Log;
06.import android.view.Window;
07.import android.widget.ImageView;
08.public class Main extends Activity {
09.    ImageView iv;
10.    @Override
11.    public void onCreate(Bundle savedInstanceState) {
12.        super.onCreate(savedInstanceState);
13.        setContentView(R.layout.main);
14.        iv = (ImageView) this.findViewById(R.id.ImageView01);
15.        iv.post(new Runnable() {
16.            public void run() {
17.                viewInited();
18.            }
19.        });
20.        Log.v("test", "== ok ==");
21.    }
22.    private void viewInited() {
23.        Rect rect = new Rect();
24.        Window window = getWindow();
25.        iv.getWindowVisibleDisplayFrame(rect);
26.        int statusBarHeight = rect.top;
27.        int contentViewTop = window.findViewById(Window.ID_ANDROID_CONTENT)
28.                .getTop();
29.        int titleBarHeight = contentViewTop - statusBarHeight;
30.        // 测试结果：ok之后 100多 ms 才运行了
31.        Log.v("test", "=-init-= statusBarHeight=" + statusBarHeight
32.                + " contentViewTop=" + contentViewTop + " titleBarHeight="
33.                + titleBarHeight);
34.    }
35.}
