    <p>I'm making an app with a splashscreen animation. I have given the user the option of canceling the animation. </p> <p>The home screen (Home) has a TextView (tv) . I set the text during the onCreate(), and again during the onResume() .</p> <p>When running with the animation, the flow is: splashscreen -> home screen -> other activities. The text of tv is set, and then returning to the home screen it 'reloads' and sets different text.</p> <p>When the animation is canceled, it starts with the home screen: home screen -> other activities.</p> <p>THE PROBLEM: When animation is canceled, the home screen sets the text in tv2 during the onCreate() and then SETS IT AGAIN in the onResume(), even though I have added an 'if' clause to prevent this from happening.</p> <p>Here is come code:</p> <pre><code>public class Home extends Activity { public static boolean reload = true; EditText tv; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); tv= (EditText) findViewById(R.id.textViewFact); tv.setText(updateText()); MORE STUFF .... } </code></pre> <p>The 'reload' is set to false from a different activity, if the user chooses to cancel the animation.</p> <p>and now for the onResume:</p> <pre><code>public void onResume(){ super.onResume(); Log.i("test", "home activity before if: " + Home.reload); if(!reload){ Log.i("test", "home activity inside if: " + Home.reload); return; } else{ Log.i("test", "home activity inside else: " + Home.reload); tv.setText(updateText()); } } </code></pre> <p>As you can see, the updateText() runs in the onCreate() and the onResume(), yet if reload is false (which it IS, as you can see in the following logcat output), it SHOULD NOT be running the updateText() again.</p> <pre><code>01-30 08:44:50.140: I/test(551): home activity before if: false 01-30 08:44:50.140: I/test(551): home activity inside if: false 01-30 08:44:51.170: I/test(551): home activity before if: false 01-30 08:44:51.170: I/test(551): home activity inside if: false </code></pre> <p>I don't know why it is getting into the onResume() TWICE (which it is, by the log output), and how it is even running the updateText() function, when that is only inside the ELSE clause, which isn't reached, according to the log output.</p>

    1. COI think you should need to go through the life cycle of activity then you will understand on your own why its happening.

    3. COHave you understood the activity lifecycle? onResume() will _always_ be called, it is _not_ an _either-or_ regarding onCreate(). Also, what is the distinction good for anyways?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
