我尝试了此测试,但getHits()始终返回0。有人可以帮助我吗?

 public void testSettingsAboutShazamClickOnLink() {

    Instrumentation inst = getInstrumentation();
    IntentFilter intentFilter = new IntentFilter(android.content.Intent.ACTION_SENDTO);
    intentFilter.addDataScheme("mailto");


    ActivityMonitor monitor = inst.addMonitor(intentFilter, null, false);
    final Intent emailIntent = new Intent(android.content.Intent.ACTION_SENDTO);
    emailIntent.setData(Uri.parse("mailto:"));
    emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);


    assertEquals(0, monitor.getHits());
    inst.getContext().startActivity(emailIntent);
    monitor.waitForActivityWithTimeout(5000);
    assertEquals(1, monitor.getHits());
    inst.removeMonitor(monitor);
 }

最佳答案

我解决了这个问题。我使用了Robotium的Solo,显然Solo插入了一个与每个Filter匹配的ActivityMonitor,因此,当您调用startActivity时,它将在Instrumentation类中调用execStartActivity,其代码为

 Context who, IBinder contextThread, IBinder token, Activity target,
    Intent intent, int requestCode) {
    IApplicationThread whoThread = (IApplicationThread) contextThread;
    if (mActivityMonitors != null) {
        synchronized (mSync) {
            final int N = mActivityMonitors.size();
            for (int i=0; i<N; i++) {
                final ActivityMonitor am = mActivityMonitors.get(i);
               if (am.match(who, null, intent)) {
                   am.mHits++;
                    if (am.isBlocking()) {
                        return requestCode >= 0 ? am.getResult() : null;
                    }
                   break;
                }
            }
       }
    }


一旦有一个ActivityMonitor与之匹配,该监视器的mHits就会增加,“中断周期”结束。鉴于调用Solo是我做的第一件事,因此要检查的第一个ActivityMonitor是Solo,因为它匹配所有内容,因此不检查之后添加的任何其他ActivityMonitors,因此其他监视器不会增加mHits变量。如果您想了解更多信息,请参见Instrumentation类的execStartMonitor方法,请记住在调用startActivity之后将调用此方法。
