Android获取状态栏和标题栏的高度

http://blog.csdn.net/pilou5400/article/category/758185/2

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。

view
plain

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。

view
plain

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：

view
plain

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);

}

}

view
plain

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent">

<ImageView

android:id="@+id/ImageView01"

android:layout_width="wrap_content"

android:layout_height="wrap_content"/>

</LinearLayout>
