Code Implementation

1. add permissions (in the AndroidManifest. xml file)

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2. Add one Button (activity_main.xml file)

<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>

3. Implement screenshot (MainActivity. java file)

Package com. example. androidtest; import java. io. file; import java. io. fileOutputStream; import android. OS. bundle; import android. OS. environment; import android. app. activity; import android. graphics. bitmap; import android. view. menu; import android. view. view; import android. widget. button; public class MainActivity extends Activity {@ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (save DInstanceState); setContentView (R. layout. activity_main); Button btn = (Button) this. findViewById (R. id. btn_save); btn. setOnClickListener (new View. onClickListener () {@ Overridepublic void onClick (View v) {screenshot () ;}}) ;}private void screenshot () {// get the screen View dView = getWindow (). getDecorView (); dView. setDrawingCacheEnabled (true); dView. buildDrawingCache (); Bitmap bmp = dView. getDrawingCache (); if (bmp! = Null) {try {// get the built-in SD card path String sdCardPath = Environment. getExternalStorageDirectory (). getPath (); // image File path String filePath = sdCardPath + File. separator + "screenshot.png"; File file = new File (filePath); FileOutputStream OS = new FileOutputStream (file); bmp. compress (Bitmap. compressFormat. PNG, 100, OS); OS. flush (); OS. close ();} catch (Exception e) {}}@ Overridepublic boolean onCreateOptionsMenu (Menu menu) {// Inflate the menu; this adds items to the action bar if it is present. getMenuInflater (). inflate (R. menu. activity_main, menu); return true ;}}
