Android获取状态栏和标题栏的高度

[转]
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);
	}
}
