Deleting image from imageview

I'm facing problem in deleting image from imageView hot to delete it from the activity as well as the external media of the file location.

Trying it since 3 days and found no solution yet. I need to apply the delete button code in this java file

public class FullScreenImageAdapter extends PagerAdapter {

private Activity _activity;
private ArrayList<String> _imagePaths;
private LayoutInflater inflater;

// constructor
public FullScreenImageAdapter(Activity activity,
        ArrayList<String> imagePaths) {
    this._activity = activity;
    this._imagePaths = imagePaths;
}

@Override
public int getCount() {
    return this._imagePaths.size();
}

@Override
public boolean isViewFromObject(View view, Object object) {
    return view == ((RelativeLayout) object);
}

@Override
public Object instantiateItem(ViewGroup container, final int position) {
    TouchImageView imgDisplay;
    Button btnClose, deleteButton;

    inflater = (LayoutInflater) _activity
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View viewLayout = inflater.inflate(R.layout.layout_fullscreen_image,
            container, false);

    imgDisplay = (TouchImageView) viewLayout.findViewById(R.id.imgDisplay);
    btnClose = (Button) viewLayout.findViewById(R.id.btnClose);
    deleteButton = (Button) viewLayout.findViewById(R.id.btndelete);
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inPreferredConfig = Bitmap.Config.ARGB_8888;
    Bitmap bitmap = BitmapFactory.decodeFile(_imagePaths.get(position),
            options);
    imgDisplay.setImageBitmap(bitmap);

    // close button click event
    btnClose.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            _activity.finish();
        }
    });




    deleteButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
        // TODO Auto-generated method stub




            String myFile = "/FakeNewsMaker/File.jpg";  

            // File file = new File(imagePath);
         //     if(file.exists())
            //      file.delete();

        }
        });





    ((ViewPager) container).addView(viewLayout);

    return viewLayout;
}






protected void startActivity(Intent createChooser) {
    // TODO Auto-generated method stub

}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    ((ViewPager) container).removeView((RelativeLayout) object);

}
}

you can delete the the imageFile like this.

 public void DeleteFile(String fullPath, int position) {

    try {
        File sdCardRoot = Environment.getExternalStorageDirectory();
        Log.w("SDCardRoot", "" + sdCardRoot);
        File yourDir = new File(sdCardRoot, "/YourFolderName");
        if (!yourDir.exists()) {
            yourDir.mkdirs();
            Log.w("DashBordAct DirName:", "" + yourDir);
        }

        if (yourDir.isDirectory()) {
            File[] content = yourDir.listFiles();
            for (int i = 0; i < content.length; i++) {
                if (content[i].toString().contains(fullPath)) {
                    boolean success = content[i].delete();
                    if (!success) {
                        Log.w("file", "not deleted);
                    } else {
                        Log.w("file", "deleted");
                        _imagePath.remove(position);
                        notifyItemRemoved(position);

                    }
                }
            }
        }
    } catch (NullPointerException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }

}

and set this method in DeleteButton listener like this:

deleteButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            String myFile = "/FakeNewsMaker/File.jpg";  
            DeleteFile(imagePath, getAdapterPosition) //or myFile.
        }
        });

and also set permission in manifest.

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

To remove from ImageView @Narendra Sorathiya solution is fine if you also want delete it from storage then use the combination.

deleteButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
        // TODO Auto-generated method stub

            imgDisplay.setImageBitmap(null);
            String myFile = v.getTag().toString();  

            File file = new File(myFile);
            if(file.exists())
               file.delete();
            }
        });

Update:

 deleteButton = (Button) viewLayout.findViewById(R.id.btndelete);
 // add below line after deleteButton 
 deleteButton.setTag(_imagePaths.get(position));

And then get Tag when delete button clicked like this 

String myFile = v.getTag().toString();

I update the code in above section.

Just set image bitmap to null like this -

 imgDisplay.setImageBitmap(null);

You may use,

imgView.setImageResource(0);

or

imgView.setImageResource(android.R.color.transparent);

or

imgView.setImageBitmap(null);
imgView.destroyDrawingCache();

I hope this works for you !
