Question

大家好我想在默认的来电活动中调用我自己的活动..我已经使用广播接收器这样做了我在接听来电时调用我的活动。但是，当我接到来电时，它第一次正常工作，然后默认来电活动即将到来。我不知道有什么问题可以帮助我..

Java代码：

public void onReceive(Context context, Intent intent) {

                    i.setAction(CUSTOM_INTENT);
                    context.sendBroadcast(i);

        }
    }

}


public class TestReceiver extends BroadcastReceiver {

    if (intent.getAction().equals(MyCallReceiver.CUSTOM_INTENT)) {
        System.out.println("GOT THE INTENT");
        context.startActivity(new Intent(context, CallActivity.class)
                .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
    }

实际上我在上面发布的完整代码只是替换下面的代码

public class TestReceiver extends BroadcastReceiver{

public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(MyCallReceiver.CUSTOM_INTENT)) {
    System.out.println("GOT THE INTENT");
    context.startActivity(new Intent(context, CallActivity.class)
            .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
}
}
 }

使用以下代码

 public class TestReceiver extends BroadcastReceiver{

@Override
public void onReceive(final Context context, Intent intent) {
    if (intent.getAction().equals(MyCallReceiver.CUSTOM_TEST_INTENT)) {
        System.out.println("GOT THE INTENT");
        final String mobileNumber = intent.getExtras().getString("number");
        Thread thread = new Thread(){
            private int sleepTime = 400;

            @Override
            public void run() {
                super.run();
                try {
                    int wait_Time = 0;

                    while (wait_Time < sleepTime ) {
                        sleep(100);
                        wait_Time += 100;
                    }
                }catch (Exception e) {
                    Toast.makeText(context,
                            "Error Occured Because:" + e.getMessage(),
                            Toast.LENGTH_SHORT).show();
                }
                finally {

                }

                context.startActivity(new Intent(context, CallActivity.class).putExtra("number", mobileNumber)
                        .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
            }
        };
        thread.run();
    }
}
 }

我创建了一个调用我的活动的线程，并且我在该启动活动之前编写了一个语句，该活动睡眠时间为500毫秒。这是我的解决方案......如果任何人不在statd下，那么问我，我会在这里发布代码。

如何在接听来电时呼叫活动。
