Hello all,
I'm new to Android development, and am a bit confused here. I'm
hoping someone can help me out. I hope I've got the correct list.
Anyway, I've got a very simple Activity, one EditText and one Button.
Lets call it MyActivity. Now, when I click on the button on
MyActivity, I want to take a picture using the camera. For the sake
of this e-mail, lets call the activity that gets spawned when I click
on the button CameraActivity.
Here is how I've setup my button:
Button takePictureButton = (Button)
this.findViewById(R.id.receipt_take_picture_button);
takePictureButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
ContentValues values = new ContentValues();
values.put(Media.TITLE, "IMAGE");
values.put(Media.DESCRIPTION, "Image Captured
by Camera");
Uri uri =
getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
Intent i = new
Intent("android.media.action.IMAGE_CAPTURE");
i.putExtra("output", uri);
startActivityForResult(i,
ACTIVITY_TAKE_PICTURE_WITH_INTENT);
}
});
As I understand it, click the button will cause MyActivity to start up
CameraActivity, which is just the default camera application, to take
a picture. Because I've used startActivityForResult, when
CameraActivity finishes, MyActivity should be notified via it's
onActivityResult. Below is how I've coded it up:
I've defined my onActivityResult as follows:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent
data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case (ACTIVITY_TAKE_PICTURE_WITH_INTENT):
Log.d(TAG, "WOW!");
default:
break;
}
}
So, what has me confused is this: I would expect onActivityResult to
be called AFTER I take a picture, i.e. when I click on the picture
button. Instead, it seems to get called immediately: I click on the
takeAPictureButton, the camera activity starts up at about the same
time the code in onActivityResult gets fired. Am I missing something
here?
