If you create a <code>setUp()</code> method like this in your test case extending <code>ActivityInstrumentationTestCase2&lt;MyActivity&gt;</code>

<pre><code>@Override
protected void setUp() throws Exception {
 super.setUp();

 final MyActivity activity = getActivity();

 tv1 = (EditNumber)activity.findViewById(resId1);
 tv2 = (EditNumber)activity.findViewById(resId2);
}
</code></pre>

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

<pre><code>@SmallTest
public void testSimpleCreate() {
 final MyActivity activity = getActivity();
 assertNotNull(activity);

 assertNotNull(tv1);
 assertEquals("mystr1", tv1.getText().toString());
 assertNotNull(tv1);
 assertEquals("mystr2", tv2.getText().toString());
}
</code></pre>

As I mentioned in <a href="https://stackoverflow.com/questions/2089489/how-can-you-tell-when-an-android-activity-is-finished-loading#comment-2022516">a comment</a>, your view hierarchy should be working after your call to <code>setContentView()</code> early in <code>onCreate()</code>. I've never had any problems like this with any activity or test class..

I'm not sure this is of any help for this specific case, but in general you can determine when the UI event queue is empty by calling <a href="http://developer.android.com/reference/android/app/Instrumentation.html#waitForIdleSync%28%29" rel="nofollow noreferrer"><code>getInstrumentation().waitForIdleSync()</code></a>. That'll block until there's no more UI events to process.

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?

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

我正在为我们的android应用程序开发一个自动化测试套件，在等待活动完全加载时遇到了麻烦。我可以调用getActivity，但仅仅因为它显示了我希望在测试中看到的活动，并不总是意味着该活动的组件就可以使用(完全加载)。查看Activity API没有发现任何问题，而其他方法似乎过于侵入性，破坏了测试的初始状态。有没有...
