Blurred image in Imageview

Activity Class :

   public class MainActivity extends ActionBarActivity {
   Button b1,b2;
   ImageView iv;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);

      b1=(Button)findViewById(R.id.button);
      iv=(ImageView)findViewById(R.id.imageView);

      b1.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, 0);
         }
      });
   }

   protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      // TODO Auto-generated method stub
      super.onActivityResult(requestCode, resultCode, data);

      Bitmap bp = (Bitmap) data.getExtras().get("data");
      iv.setImageBitmap(bp);
   }

File is being saved in sdcard and also I retrive its URI sucessfully, but still imageview do not show this image or imageview disappear when camera click and return. Code are as follows -:

public class MainActivity extends Activity {

    static int TAKE_PIC =1;
    Uri outPutfileUri;
    ImageView mImageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mImageView = (ImageView) findViewById(R.id.image);
    }


    public void CameraClick(View v) {

        Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        File file = new File(Environment.getExternalStorageDirectory(),
                "MyPhoto.jpg");
        outPutfileUri = Uri.fromFile(file);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutfileUri);
        startActivityForResult(intent, TAKE_PIC);
    }

    Bitmap bitmap = null;

    @Override
    protected void onActivityResult(int requestCode, int resultCode,Intent data)
    {
        if (requestCode == TAKE_PIC && resultCode==RESULT_OK) {

            String uri = outPutfileUri.toString();
            Log.e("uri-:", uri);
             mImageView.setImageURI(Uri.parse(uri));
        }
}}

Please suggest me how to get path of clicked image and set it to imageview. I am new here.

First of all, the image is blurred because the intent data contains only the thumbnail of the image.

you must save the image on the internal/external storage and then acquire it.

feel free to take a look at the android developers documentation regarding camera images:

Android Developers

and this older SO answer explains how to retrieve the full size image after saving it :

Android get full size image from camera

if the app crashes, copy the stackstrace to your question so we can see it. – CptEric Dec 03 '15 at 10:45
you are trying to get the uri from the "data" thumbnail, that will never work. you must follow the android developers tutorial i linked to correctly save on a accessible directory and, on capture result, access the directory and retrieve it. – CptEric Dec 03 '15 at 10:56
a single line won't make all the work the rest of the code in this, http://developer.android.com/intl/es/training/camera/photobasics.html , previously linked tutorial. you must prepare the camera first, and after it's retrieved, decode it. – CptEric Dec 03 '15 at 10:59

Try This,

public class MainActivity extends Activity {

    static int TAKE_PIC =1;
    Uri outPutfileUri;
    ImageView mImageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mImageView = (ImageView) findViewById(R.id.image);
    }


    public void CameraClick(View v) {

        Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        File file = new File(Environment.getExternalStorageDirectory(),
                "MyPhoto.jpg");
        outPutfileUri = Uri.fromFile(file);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutfileUri);
        startActivityForResult(intent, TAKE_PIC);
    }

    Bitmap bitmap = null;

    @Override
    protected void onActivityResult(int requestCode, int resultCode,Intent data)
    {
        if (requestCode == TAKE_PIC && resultCode==RESULT_OK) {

            String uri = outPutfileUri.toString();
            Log.e("uri-:", uri);
            Toast.makeText(this, outPutfileUri.toString(),Toast.LENGTH_LONG).show();

            //Bitmap myBitmap = BitmapFactory.decodeFile(uri);
           // mImageView.setImageURI(Uri.parse(uri));   OR drawable make image strechable so try bleow also

            try {
                bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), outPutfileUri);
                Drawable d = new BitmapDrawable(getResources(), bitmap);
                mImageView.setImageDrawable(d);
            } catch (IOException e) {
                e.printStackTrace();
            }


        }
}

}

Hope this will help you enjoy!!!!!
