how can you tell when an Android activity is finished loading?

android, android-activity, loaded, view

Solution

If you create a `setUp()` method like this in your test case extending `ActivityInstrumentationTestCase2<MyActivity>`

@Override
protected void setUp() throws Exception {
    super.setUp();

    final MyActivity activity = getActivity();

    tv1 = (EditNumber)activity.findViewById(resId1);
    tv2 = (EditNumber)activity.findViewById(resId2);
}

your Activity will be fully operational and the layout loaded, demonstrated in this case by the fact that you can access the Views and its content

@SmallTest
public void testSimpleCreate() {
    final MyActivity activity = getActivity();
    assertNotNull(activity);

    assertNotNull(tv1);
    assertEquals("mystr1", tv1.getText().toString());
    assertNotNull(tv1);
    assertEquals("mystr2", tv2.getText().toString());
}

Problem

I'm in the process of working on an automated test suite for our android app, and running into trouble waiting for activities to fully load. I can call getActivity, but just because it shows the activity that I'm hoping to see in my test doesn't always seem to mean that the activity's components are ready for use (fully loaded). Looking through the Activity API didn't turn anything up, and other methods seem too invasive and have spoiled the tests initial state. Does anyone know if there's a way to ask the app or the VM if the current activity is loaded?
