14,892 PointsTransitions postponement
The Activity below is displaying images downloaded from the internet. Postpone the enter transition for this activity until the images are downloaded and set, which happens in the initViews() method.
public class MainActivity extends Activity {
// Some code omitted for brevity!
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_album_detail);
setupTransitions();
initViews{postponeEnterTransition()};
}
public void setupTransitions() {
// (Omitted) Code to set up transitions...
}
public void initViews() {
// (Omitted) Code to initialize all views in the Activity...
}
}

Treehouse TeacherAlright, let's check out this line:
initViews{postponeEnterTransition()};
First, you've added curly braces instead of parentheses, which will give you a syntax error.
Second, if you look at the definition for initView(), you'll see that it doesn't take any parameters, so you wouldn't want to add postponeEnterTransition() or anything else in there.
So you'll need to change that line back to its original form: initViews();
Then, you are on the right track with using postponeEnterTransition()--you just need to call it in the right place. Here's your hint: You want to call this method as the transitions are being setup.
