Android screenshot from code. Got it but not perfect

Question

I\'m trying to take a screenshot in code in Android. Actually the screenshot is the bitmap of the main RelativeLayout. The screenshot is taken but the content appears wrong, the

Answer 1

This works good for me:

View content = findViewById(R.id.myElementForScreenshoot);
View screenshot = content; // or content.getRootView() for fullscreen
screenshot.refreshDrawableState();
screenshot.setDrawingCacheEnabled(true);
Bitmap b = screenshot.getDrawingCache();    

After this you can process or save bitmap. Hope it helped. Cheers

Answer 2

I'm assuming you're doing this during creation. Don't!

use a postDelayed(Runnable, int) to execute the Bitmap bm = Bitmap.createBitmap(v.getDrawingCache()); after the view is drawn.

also, remove the v.measure() and v.layout() those are methods for the ViewGroup to be calling.

Answer 3

Remove the lines:

v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
//v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
v.layout(0, 0, v.getWidth(), v.getHeight());

Answer 4

I think you need to replace the

RelativeLayout v = (RelativeLayout)findViewById(R.id.main_layout);

v.setDrawingCacheEnabled(true);

v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));

v.layout(0, 0, v.getWidth(), v.getHeight());

v.buildDrawingCache(true);

Bitmap bm = Bitmap.createBitmap(v.getDrawingCache());

v.setDrawingCacheEnabled(false);

with

Bitmap bitmap;

View root = findViewById(android.R.id.content);

View v1 = root.getRootView();

v1.setDrawingCacheEnabled(true);

root.setDrawingCacheEnabled(true);

Bitmap bm = Bitmap.createBitmap(root.getDrawingCache());

root.setDrawingCacheEnabled(false);

Answer 5

Specify the screen size in makeMeasureSpec

...
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
v.measure(MeasureSpec.makeMeasureSpec(0, size.x),
            MeasureSpec.makeMeasureSpec(0, size.y));
...

Also try setting the setDrawingCacheQuality to high, so that it returns a higher resolution bitmap.

Answer 6

LinearLayout ll = (LinearLayout )findViewById(R.id.layout); ll .setDrawingCacheEnabled(true); Bitmap bm = v1.getDrawingCache();

Try this
