Passing image to another activity

We want to pass a picture to another activity. For example, a screenshot of running app.

Use this code.

layout.setDrawingCacheEnabled(true);              layout.setDrawingCacheQuality(LinearLayout.DRAWING_CACHE_QUALITY_HIGH);

layout.buildDrawingCache();

Bitmap b = layout.getDrawingCache();

ByteArrayOutputStream stream = new ByteArrayOutputStream();

b.compress(Bitmap.CompressFormat.PNG, 100, stream);

byte[] byteArray = stream.toByteArray();

Intent in = new Intent(MainActivity.this, newclass.class);

in.putExtra("image",byteArray);                 

startActivity(in);

layout is the LinearLayout you set for screen that take picture.

In new class, we receive bitmap image and set it to imageView.

byte[] byteArray = getIntent().getByteArrayExtra("image");

Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

image.setImageBitmap(bmp);

If picture too large, we want to resize it to smaller, about 60% of original size.

int srcWidth = bmp.getWidth();

int srcHeight = bmp.getHeight();

int dstWidth = (int)(srcWidth*0.6f);

int dstHeight = (int)(srcHeight*0.6f);

image.setImageBitmap(Bitmap.createScaledBitmap(bmp, dstWidth, dstHeight, true));
