Android 获取标题栏与状态栏的高度
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。
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。
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:
package com.cn.lhq;
import android.app.Activity;
import android.graphics.Rect;
import android.os.Bundle;
import android.util.Log;
import android.view.Window;
import android.widget.ImageView;
public class Main extends Activity {
ImageView iv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
iv = (ImageView) this.findViewById(R.id.ImageView01);
iv.post(new Runnable() {
public void run() {
viewInited();
}
});
Log.v("test", "== ok ==");
}
private void viewInited() {
Rect rect = new Rect();
Window window = getWindow();
iv.getWindowVisibleDisplayFrame(rect);
int statusBarHeight = rect.top;
int contentViewTop = window.findViewById(Window.ID_ANDROID_CONTENT)
.getTop();
int titleBarHeight = contentViewTop - statusBarHeight;
// 测试结果:ok之后 100多 ms 才运行了
Log.v("test", "=-init-= statusBarHeight=" + statusBarHeight
+ " contentViewTop=" + contentViewTop + " titleBarHeight="
+ titleBarHeight);
}
}
