I am currently trying to make a Dialog using Implicit Intent where i want to show my Dialog like whatsApp(Profile Photo Screen) and in this screen whatsApp are using extra field named as "Remove Photo". When i try to make same type of screen Dialog then i am unable to add this extra field("Remove Photo"). i have done all code. its working fine for three option in Dialog like(Gallery,Photo,Camera) and i am unable to handle these all in onActivityResult() . I am sending my all source code i have tried much hard , but i am not able to find the solution to do so. plz..... friends help me out from this.

In this code i am simply create a method named as openFileChooser() in which i have write all the code for creating Dialog Screen and handle this outcomes in onActivityResult()

Here Is my code

ProfilePhotoActivity.java

public class ProfilePhotoActivity extends Activity implements OnClickListener{
    ImageButton back, editPhoto, selectAction;
    ImageView imgCamera;
    private static final int FILECHOOSER_RESULTCODE   = 2888;
    protected static final int CAMERA_REQUEST = 0;
    protected static final int GALLERY_PICTURE = 1;
    private Uri mCapturedImageURI = null;
    Intent intent;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_profilephoto);

        back=(ImageButton)findViewById(R.id.btn_back);
        editPhoto=(ImageButton)findViewById(R.id.ibEditPhoto);
        selectAction=(ImageButton)findViewById(R.id.ibSelectAction);

        imgCamera=(ImageView)findViewById(R.id.imvProfilePhoto);

        editPhoto.setOnClickListener(this);
        selectAction.setOnClickListener(this);
        back.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {

        switch (v.getId()) {
        case R.id.btn_back:
            ProfilePhotoActivity.this.finish();
            break;

        case R.id.ibEditPhoto:
            openFileChooser(null, null);
        //  startDialog();

Answer 1

This looks like it will be a problem:

 if(requestCode==FILECHOOSER_RESULTCODE)  
          {  
              if (requestCode == GALLERY_PICTURE)

unless FILECHOOSER_RESULTCODE and GALLERY_PICTURE are the same ints then statement will never pass.

Answer 2

It may be possible to use request code to distinguish between "types" of photos i.e.

protected static final int MY_FACE_PHOTO    = 0;
protected static final int MY_CAR_PHOTO     = 1;
protected static final int MY_HOUSE_PHOTO = 2;

And you may use Intent.putExtra(String name, String value) when you create Intents before starting new activity, like:

@NonNls protected static final String STRING_EXTRA = "string_extra";
@NonNls protected static final String CAMERA           = "camera";
@NonNls protected static final String GALLERY          = "gallery";

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Intent galleryIntent  = new Intent(Intent.ACTION_PICK, 
                               MediaStore.Images.Media.EXTERNAL_CONTENT_URI

cameraIntent.putExtra(STRING_EXTRA, CAMERA);
galleryIntent.putExtra(STRING_EXTRA, GALLERY)

startActivityForResult(takePicture, 
                                MY_FACE_PHOTO /* put here your desired request code */)

After that in onActivityResult() method you may use them:

 protected void onActivityResult (int requestCode, int resultCode, Intent intent) 
 {
   super.onActivityResult(requestCode, resultCode, intent);

    if(intent != null)
    {
       if(resultCode == Activity.RESULT_OK)
       {
          String extraString = intent.getStringExtra(STRING_EXTRA);

           if(extraString.equals(CAMERA))
           {
              // ... i. e.
              switch (requestCode)
              {
                  case MY_FACE_PHOTO:
                  {
                       // ...
                       break;
                  }
                  case MY_CAR_PHOTO:
                  {
                       // ...
                       break;
                  }
                  case MY_HOUSE_PHOTO:
                  {
                      // ...
                      break;
                  }
                  default:
                  {
                      // ...
                      break;
                  }
              } 
           }
           else if(extraString.equals(GALLERY))
           {
              // ...
           }
       }
       else
       {
           // ...
       }
    }
 }
