This shouldn't be too tough of a question. I want the ability to take a screenshot of my layout (view) and send it via sms. Can someone walk me though the steps?

Thanks!

Edit: It doesn't have to be a 'screenshot' I guess, just as long as we can get all of the rendered pixels from a view somehow.

Around the web I found some snippets of code that I was able to get working together.

Here is a solution that works well:

Setting up your Root layout:

View content = findViewById(R.id.layoutroot);
content.setDrawingCacheEnabled(true);

Function to get the rendered view:

private void getScreen()
{
    View content = findViewById(R.id.layoutroot);
    Bitmap bitmap = content.getDrawingCache();
    File file = new File("/sdcard/test.png");
    try 
    {
        file.createNewFile();
        FileOutputStream ostream = new FileOutputStream(file);
        bitmap.compress(CompressFormat.PNG, 100, ostream);
        ostream.close();
    } 
    catch (Exception e) 
    {
        e.printStackTrace();
    }
}

    Remember to add `` to your AndroidManifest and instead of hardcoding `/sdcard/` use `File file = new File( Environment.getExternalStorageDirectory() + "/test.png");` – Macarse Jun 07 '11 at 12:22

    @Peanut i used this solution. test.png is created in sdcard. but actully the image is not created it shows 0kb. and i get the null pointer exception here " bitmap.compress(CompressFormat.PNG, 100, ostream);" – vnshetty Jul 21 '11 at 04:16
