如何使用android延迟不扩展或实现Thread或Runnable

Question

我是新来的，我想知道如何在不使用线程的情况下在android中使用延迟。 我正在使用Handler

Handler handler=new Handler();
Thread r=new Thread () {
    public void run() {
        // Your next task
    }
};
handler.postDelayed(r, 30000);

Answer 1

替换Thread r = new Thread with Runnable

Handler handler=new Handler();
            Runnable r=new Runnable() {
                public void run() {
                    // Your next task
                }
            };
            handler.postDelayed(r, 30000);

Answer 2

试试这个

Handler handler = new Handler();

handler.postDelayed(new Runnable() {
    public void run() {
        // Your next task
    }
}, 30000);
