Question

In my program, there is some textfields and a button which is opens a camera intent. (assume that the page’s name is mainIntent)… Lets assume that, user fills textfields and clicked the button; cameraIntent opens, user shots the photo.. Now, I want program to return the page which have textfields and button. But if I do

Intent i = new Intent(cameraIntent.this, mainIntent.class);
startActivity(i);

All the texts which are written by user are gone. I need to use something like return mainIntent I suppose…

Can someone help me?

Use startActivityForResult in first activity. So you will be able to return to calling activity. And you won’t lose data of edit texts.

Intent i = new Intent(mainIntent.this, cameraIntent.class);
startActivityForResult(i, MY_REQ_CODE);

You can add this for onActivityResult():

protected void onActivityResult(int requestCode, int resultCode, Intent data)
      {
      switch(requestCode) {
      case MY_REQ_CODE: 
            if (resultCode == RESULT_OK) {
                //Do action that's needed
                break;
            }

      }
}

In your activity next activity, you will just need to call setResult() and finish() as follows. You won’t need to start new activity here:

Intent returnIntent = new Intent();
returnIntent.putExtra("ImageName",imgName);   //Required if you want to pass some data back
setResult(RESULT_OK,returnIntent);        
finish(); 

Hope it helps.
