推荐答案

据我从我跟着拉尔斯·沃格尔的教程我记得，我有同样的问题。这其实不是你已经指出的问题。

As far as I remember from when I followed Lars Vogel's tutorial myself, I had the same problem. It's actually not the problem that you have stated.

尝试把一个断点在的onReceive（）函数来手动看到你所得到的有效载荷。在我的情况下，消息是好的，但 MessageReceivedActivity 不是，它总是呈现坏消息。

Try putting a breakpoint in the onReceive() function to manually see the payload you are getting. In my case, the message was good, but the MessageReceivedActivity was not, and it was always showing the bad message.

从MessageReceivedActivity把 super.onCreate（）方法的方法之上。

Put the super.onCreate() method from the MessageReceivedActivity on top of the method.

如何为：

@Override
protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_result);
    Bundle extras = getIntent().getExtras();
    if (extras != null) {
        String message = extras.getString("payload");
        if (message != null && message.length() > 0) {
            TextView view = (TextView) findViewById(R.id.result);
            view.setText(message);
        }
    }

    super.onCreate(savedInstanceState);
}

应如何：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_result);
    Bundle extras = getIntent().getExtras();
    if (extras != null) {
        String message = extras.getString("payload");
        if (message != null && message.length() > 0) {
            TextView view = (TextView) findViewById(R.id.result);
            view.setText(message);
        }
    }
}
