android开发中通过View的getDrawingCache方法可以达到截屏的目的,只是缺少状态栏!
原始界面
截屏得到的图片
代码实现
1. 添加权限(AndroidManifest.xml文件里)
- <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
3. 实现截屏(MainActivity.java文件)
- <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
- xmlns:tools="http://schemas.android.com/tools"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- tools:context=".MainActivity" >
- <TextView
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_centerHorizontal="true"
- android:layout_centerVertical="true"
- android:text="@string/hello_world" />
- <Button
- android:id="@+id/btn_save"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="Screenshot"
- />
- </RelativeLayout>
