Question

我在android中同时执行两个线程时遇到问题。通过一个线程处理一个方法，该方法在一定的时间间隔后被执行并且另一个尝试在几个按钮上处理onClick响应，但问题是只有一个线程正在执行，即调用该方法的线程。请给我解决方案。在期待中感谢你。

Thread th=new Thread(){

            @Override

使用

Your_Current_activity.this.runOnUiThread(new Runnable() {
    public void run() {
        // your UI code here
    });

因为runOnUiThread是Activity类的方法而不是Thread

Android线程异常
