Android window screenshot

Steps:

Step 1: Obtain the Bitmap object that saves the screen image;

Step 2: Obtain the height of the status bar;

Step 3: Obtain the screen image height;

Step 4: Create a New Bitmap object and intercept other regions except the status bar;

Step 5 Save the screen image to the root directory of the SD card

The Code is as follows:

Package com. example. activityproperty; import java. io. file; import java. io. fileOutputStream; import java. io. IOException; import android. annotation. suppressLint; import android. app. activity; import android. graphics. bitmap; import android. graphics. point; import android. graphics. rect; import android. OS. bundle; import android. OS. handler; import android. view. view; import android. widget. toast; public class MainActivit Y extends Activity {@ Overrideprotected void onCreate (Bundle savedInstanceState) {// TODO Auto-generated method stubsuper. onCreate (savedInstanceState); setContentView (R. layout. activity_main) ;}@ SuppressLint ("NewApi") public void onClick_CaptureScreen (View view) {// use delayed running to prevent the screen image from being captured even when the button is clicked. new Handler (). postDelayed (new Runnable () {@ SuppressLint ("NewApi") @ Overridepublic void run () {// obtain the window's top-level view object Vi Ew v = getWindow (). getDecorView (); v. setDrawingCacheEnabled (true); v. buildDrawingCache (); // Step 1: Obtain the Bitmap object of the saved screen image. Bitmap srcBitmap = v. getDrawingCache (); Rect frame = new Rect (); // decorView is the top-level view in the window, which can be obtained from the window, then, decorView has a getWindowVisibleDisplayFrame method to obtain the display area of the program, including the title bar, but not the status bar. GetWindow (). getDecorView (). getWindowVisibleDisplayFrame (frame); // The height of the status bar int statusHeight = frame in step 2. top; // Step 3: Obtain the Screen Image Height Point outSize = new Point (); getWindowManager (). getdefadisplay display (). getSize (outSize); int width = outSize. x; int height = outSize. y; // create a new Bitmap object in step 4 and intercept Bitmap = bitmap in other regions except the status bar. createBitmap (srcBitmap, 0, statusHeight, width, height-statusHeight); v. destroyDrawingCache (); FileOutputStream fos = null; try {File file = File. createTempFile ("capture ",". jpg ", new File ("/sdcard "); fos = new FileOutputStream (file); if (null! = Fos) {// Step 5: Save the screen image to the root directory bitmap of the SD card. compress (Bitmap. compressFormat. PNG, 90, fos); fos. flush (); Toast. makeText (MainActivity. this, "saved successfully" + file. getName (), 0 ). show ();} else {Toast. makeText (MainActivity. this, "failed", 0 ). show ();} fos. close ();} catch (IOException e) {// TODO Auto-generated catch blocke. printStackTrace () ;}}, 2000 );}}

Note that permissions for operations on SD must be added.
