Android获取状态栏和标题栏的高度
Android获取状态栏和标题栏的高度
1.获取状态栏高度:
decorView是window中的*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;@Overridepublic 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);}}
- <?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>
