Java 更改数据值后如何重新启动处理程序？

早上好StackOverFlow我的

处理程序有一些问题

我正试图在

main活动

myClient.java中启动，50秒后发送消息并停止客户端，这就是工作，但每次更改

ip\U txt

或

term\u txt

在设置中。java （通过单击按钮将数据从EditText保存到DB）

这是我的主要活动：

        public class MainActivity extends AppCompatActivity {
    Server server;
    Client client;
    Handler handler = new Handler();
    Runnable runnable = new Runnable() {
    @Override
    public void run() {
        new ConnectTask().execute("");
        if (client != null) {
            client.sendMessage("IP#" + ipp + " " + "N#" + trm);
        }
        if (client != null) {
            client.stopClient();
        }
    }
};
settings Settings;
public static TextView terminale, indr, msg;
TextView log;
String ipp,trm;
DataBaseHandler myDB;
allert Allert;
SharedPreferences prefs;

（如果我没有解释，我想在应用程序开始时启动

处理程序
，并且在
EditText-ip_-txt
或
EditText-term_-txt
中更改数据后立即重新启动它）。
我会创建变量来存储处理程序和可运行的，然后，如果要重新启动，只需使用：

yourHandler.removeCallback(yourRunnable);
yourHandler.postDelayed(yourRunnable,time);

开始的时候，就像你做的那样

yourHandler.postDelayed(yourRunnable,5000);

希望就是你想要的


如何创建它们：

public class ClassName{
    Handler yourHandler = new Handler();
    Runnable yourRunnable = new Runnable(){
        @Override
        public void run() {
            //yourCode
        }
    };
    // Rest of class code

}

与您在代码中所做的相同，只是在变量中。
如何创建该变量？你能为它添加一个例子吗？我刚刚用MainActivity代码更新了这个问题，当我创建runnable时，它使“new ConnectTask（）.execute（“”）”工作，但其他操作（其他2个if）没有启动。我假设您的
客户端
必须为空。实际上，它在与TCP客户端的连接中以及在第二个消息发送和停止客户端中使用了2个不同的runnable，但是我如何才能像上面所做的那样将其放在1 runnable中？比如我可以在ConnectTask和两个if之间的runnable中做一个延迟吗？当然你可以做一个延迟，只要把你的if代码放到另一个runnable中并做另一个处理程序，这将使if语句在你想要的时间后得到计算
public class ClassName{
    Handler yourHandler = new Handler();
    Runnable yourRunnable = new Runnable(){
        @Override
        public void run() {
            //yourCode
        }
    };
    // Rest of class code

}
