我将一个对象转换为JSONObject,然后获取该字符串并将其与" play_audio进行比较。"即使我的日志给了我正确的字符串,IF语句也会给出错误的结果 - 发生了什么?
JSONObject data = (JSONObject)args[0];
String command = null;
try {
command = data.getString("command");
} catch (JSONException e) {
e.printStackTrace();
}
Log.i(TAG, "<<<<---- RECEIVING COMMAND ----->>> " + command);
if (command == "ping_audio") { //WHY IS THIS FALSE?
Log.i(TAG, "<<<<---- PLAYING AUDIO ----->>> ");
}
logcat的
<<<<---- RECEIVING COMMAND ----->>> ping_audio
答案 0 :(得分:1)
尝试使用String.equals()方法 像command.equals(“ping_audio”)
if (command.equals("ping_audio") { // should give you what you want
Log.i(TAG, "<<<<---- PLAYING AUDIO ----->>> ");
}
