Take screenshot programmatically of the whole scre

问题:

I'm taking screenshot as below:

 public static Bitmap takeScreenshot(Activity activity) {  
      View view = activity.getWindow().getDecorView();  
      view.setDrawingCacheEnabled(true);  
      view.buildDrawingCache();  
      Bitmap bitmap = view.getDrawingCache();  
      Rect rect = new Rect();  
      activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);  
      int statusBarHeight = rect.top;  
      int width = activity.getWindowManager().getDefaultDisplay().getWidth();  
      int height = activity.getWindowManager().getDefaultDisplay().getHeight();  
      Bitmap bitmap2 = Bitmap.createBitmap(bitmap, 0, statusBarHeight, width,  
          height - statusBarHeight);  
      view.destroyDrawingCache();  
      return bitmap2;  
    }  

But there is a Edittext in my layout. I click it and keyboard pop up, but screenshot doesn't contain keyboard using this way. How can I take screenshot programmatically also which can also capture the keyboard?

回答1:

Read somewhere on the forums about another way: -

Process sh = Runtime.getRuntime().exec("su", null,null);
OutputStream  os = sh.getOutputStream();
os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII"));
os.flush();

You can try that out. Don't know if it works or not, just saved it for a rainy day :P.

EDIT:

Found the link to the post - How to take a screenshots?

User says, screenshots work for him. I think this should suit your requirement.

回答2:

It seems there is no way to get screenshot from screen of a device that is not rooted.Here,CommonsWare says:

If you mean "screenshot of somebody else's activity", that is not supported, for obvious privacy and security reasons.

Although you can get screenshot of emulator when your App is running!

Edit:

But there exists a library that is called ASL(Android Screenshot Library):

Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.

I did not try it,but you can see more details in about it here.
