I am developing an application where i need to crop image . But this image croping should happen on my activity only so i can not use default image cropping concept of android where image will go on another view where user can crop .
What i need is to create custom image cropper rectangle .
I am trying this from long but no luck . Would be glad if any body can help .
Thanks
my mainactivity..
public class MainActivity extends Activity {
private DragRectView view;
private ImageView original;
// private ImageView croppedImage;
/**
*
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
view = (DragRectView) findViewById(R.id.dragRect);
original = (ImageView) findViewById(R.id.image);
// croppedImage = (ImageView) findViewById(R.id.crop_image);
if (null != view) {
view.setOnUpCallback(new DragRectView.OnUpCallback() {
@Override
public void onRectFinished(final Rect rect) {
Toast.makeText(
getApplicationContext(),
"Rect is (" + rect.left + ", " + rect.top + ", "
+ rect.right + ", " + rect.bottom + ")",
Toast.LENGTH_LONG).show();
Bitmap bitmap1 = Bitmap.createScaledBitmap(
((BitmapDrawable) original.getDrawable())
.getBitmap(), original.getWidth(), original
.getHeight(), false);
System.out.println(rect.height() + " "
+ bitmap1.getHeight() + " " + rect.width()
+ " " + bitmap1.getWidth());
if (rect.height() <= bitmap1.getHeight()
&& rect.width() <= bitmap1.getWidth()) {
Bitmap bitmap = Bitmap.createBitmap(bitmap1,
view.getLeft(), view.getTop(), view.getWidth(),
view.getHeight());
System.out

it may help you...
you can try this for flexible and custom crop.....
Intent intent = new Intent("com.android.camera.action.CROP");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
intent.setType("image/*");
intent.putExtra("aspectX", 0);
intent.putExtra("aspectY", 0);
intent.putExtra("outputY", 600);
intent.putExtra("outputX", 600);
intent.putExtra("scale", "true);
