我正在努力解决一个问题,这个问题是关于在 android 的多个文本视图中显示来自代理服务器的可用 mqtt 主题,并选择其中一个来订阅主题
final MqttAndroidClient client =new MqttAndroidClient(getApplicationContext(),"tcp://iot.eclipse.org:1883","12d45454");
try {
client.connect(mqttConnectOptions, null, new IMqttActionListener() {
@Override
public void onSuccess(IMqttToken mqttToken) {
DisconnectedBufferOptions disconnectedBufferOptions = new DisconnectedBufferOptions();
disconnectedBufferOptions.setBufferEnabled(true);
disconnectedBufferOptions.setBufferSize(100);
disconnectedBufferOptions.setPersistBuffer(false);
disconnectedBufferOptions.setDeleteOldestMessages(false);
Log.i("ERROR ","Topic="+mqttToken.getTopics());
textview1.setText(mqttToken.getTopics()[0]);
}
