如何在不获取“无法对非静态方法进行静态引用"的情况下使用runOnUiThread；编译器错误 [英] how to use runOnUiThread without getting "cannot make a static reference to the non static method" compiler error

问题描述

我有一个主要班级；

  ClientPlayer extends Activity {

和一项服务

  LotteryServer extends Service implements Runnable {

当尝试在此服务的run方法中使用RunOnUiThread时，出现编译器错误，无法对非静态方法进行静态引用"

when trying to use the RunOnUiThread in the run method of this service I am getting compiler error of, "cannot make a static reference to the non static method"

如何解决此问题?，此处显示了我如何使用代码；

how to fix this?, how I am using the code is shown here;

     @Override
public void run() {
   // I tried both ClientPlayer.runOnUiThread and LotteryServer.runOnUiThread
   // both don't work   
    ClientPlayer.runOnUiThread(new Runnable() {
        public void run() {
           Toast.makeText(getApplicationContext(), "from inside thread", Toast.LENGTH_SHORT).show();
        }
    });
} // end run method

推荐答案

runOnUiThread不是静态方法.

runOnUiThread is not a static method.

如果您想在UIThread上运行您的可运行对象，则可以使用此

If u want to run your runnable on UIThread You can use this

Handler handler = new Handler(Looper.getMainLooper());

Handler handler = new Handler(Looper.getMainLooper());

这将为UI线程创建一个处理程序.

This will create a handler for UI Thread.

ClientPlayer extends Activity {
.
.
public static Handler UIHandler;

static 
{
    UIHandler = new Handler(Looper.getMainLooper());
}
public static void runOnUI(Runnable runnable) {
    UIHandler.post(runnable);
}
.
.
.
}

现在您可以在任何地方使用它了.

Now u can use this anywhere.

@Override
public void run() {
   // I tried both ClientPlayer.runOnUiThread and LotteryServer.runOnUiThread
   // both don't work   
    ClientPlayer.runOnUI(new Runnable() {
        public void run() {
           Toast.makeText(getApplicationContext(), "from inside thread", Toast.LENGTH_SHORT).show();
        }
    });
} // end run method
