How to get imageView value to insert in to Sqlite?

Question

When I click on my button I can select the photo and it shows in my imageView. But when I click to save, my imageView has become NULL. Anyone can help me? Bitmap always comes null.

I changed

Bitmap bitmap =  
((BitmapDrawable)imageViewProeto.getDrawable()).getBitmap();

to

Bitmap bitmap = imageViewProeto.getDrawingCache();

Answer 1

BitmapDrawable draw = (BitmapDrawable) iv.getDrawable();

Bitmap bitmap = draw.getBitmap();

To save Image in Your Gallery :

FileOutputStream outStream = null;
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/YourFolderName");
dir.mkdirs();
String fileName = String.format("%d.jpg", System.currentTimeMillis());
File outFile = new File(dir, fileName);
outStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush();
outStream.close();

Refresh Gallery :

Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(file));
sendBroadcast(intent);

And Dont Forget to add permission in your Menifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
