Android儀器啓動活動

Question

我有一個簡單的活動，其中包含一個按鈕。當我按下按鈕時，第二個活動運行。現在我是Android Instrumentation Testing的新手。到目前爲止，這是我寫

public class TestSplashActivity extends 
    ActivityInstrumentationTestCase2<ActivitySplashScreen> { 

private Button mLeftButton; 
private ActivitySplashScreen activitySplashScreen; 
private ActivityMonitor childMonitor = null; 
public TestSplashActivity() { 
    super(ActivitySplashScreen.class); 
} 

@Override 
protected void setUp() throws Exception { 
    super.setUp(); 
    final ActivitySplashScreen a = getActivity(); 
    assertNotNull(a); 
    activitySplashScreen=a; 
    mLeftButton=(Button) a.findViewById(R.id.btn1); 

} 

@SmallTest 
public void testNameOfButton(){ 
    assertEquals("Press Me", mLeftButton.getText().toString()); 
    this.childMonitor = new ActivityMonitor(SecondActivity.class.getName(), null, true); 
    this.getInstrumentation().addMonitor(childMonitor); 
    activitySplashScreen.runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
      // TODO Auto-generated method stub 
      mLeftButton.performClick(); 
    }}); 

    Activity childActivity=this.getInstrumentation().waitForMonitorWithTimeout(childMonitor, 5000); 
    assertEquals(childActivity, SecondActivity.class); 

} 

}

現在第一個斷言哪裏獲得按鈕作品的文本。但是，當我打電話進行點擊，我得到一個異常

Only the original thread that created a view hierarchy can touch its views. 

現在我明白了這個例外的Android應用程序上下文，但現在在儀器檢測的條件。如何在按鈕上執行點擊事件，以及如何檢查我的第二個活動是否已加載。

假設你有延伸InstrumentationTestCase測試類，和你在一個測試方法，應該遵循這樣的邏輯：

1. 註冊您在要檢查活動的興趣。
2. 啓動它
3. 做你想做的。檢查組件是否正確，執行用戶操作以及此類事情。
4. 在「序列」中註冊您對下一個活動的興趣
5. 執行該活動的動作，使該序列的下一個活動彈出。
6. 重複，按照這樣的邏輯...

在代碼方面，這將導致類似如下：

Instrumentation mInstrumentation = getInstrumentation(); 
// We register our interest in the activity 
Instrumentation.ActivityMonitor monitor = mInstrumentation.addMonitor(YourClass.class.getName(), null, false); 
// We launch it 
Intent intent = new Intent(Intent.ACTION_MAIN); 
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
intent.setClassName(mInstrumentation.getTargetContext(), YourClass.class.getName()); 
mInstrumentation.startActivitySync(intent); 

Activity currentActivity = getInstrumentation().waitForMonitor(monitor); 
assertNotNull(currentActivity); 
// We register our interest in the next activity from the sequence in this use case 
mInstrumentation.removeMonitor(monitor); 
monitor = mInstrumentation.addMonitor(YourNextClass.class.getName(), null, false); 

要發送的點擊，這樣做如下：

View v = currentActivity.findViewById(....R.id...); 
assertNotNull(v); 
TouchUtils.clickView(this, v); 
mInstrumentation.sendStringSync("Some text to send into that view, if it would be a text view for example. If it would be a button it would already have been clicked by now.");
