    capture.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");

Just try this one,

Declare this before on create method

private final int requestCode = 20;

inside onclick event, do this

Intent photoCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(photoCaptureIntent, requestCode);

then override oncreate method

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(this.requestCode == requestCode && resultCode == RESULT_OK){
        Bitmap bitmap = (Bitmap)data.getExtras().get("data");
        imageview.setImageBitmap(bitmap);
    }
}

please tell the real use of requestCode=20 – Aditya Dabas Jan 19 '18 at 06:37
You can make several calls in a single Activity to startActivityForResult() which allows different Intents to do different actions. Use a request code to identify which is the Intent you are returning from. – Poovarasan Selvaraj Jan 19 '18 at 06:45
for example: You can start two activities for result: private static final int req_1 = 1; private static final int req_2 = 2; startActivityForResult(cameraIntent, req_1); startActivityForResult(cameraIntent, req_2); and in your onActivityForResult() @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == req_1 && resultCode == RESULT_OK) { } else if (requestCode == req_2 && resultCode == RESULT_OK) { } } – Poovarasan Selvaraj Jan 19 '18 at 06:53

public String getRealPathFromURI(Uri contentUri) {
    String res = null;
    String[] proj = { MediaStore.Images.Media.DATA};
    Cursor cursor = getActivity().getApplicationContext().getContentResolver().query(contentUri, proj, null, null, null);
