android 定时器

Handler mHandler = new Handler();

Runnable mRunnable = new Runnable() {
    @Override
    public void run() {
        Toast.makeText(MainActivity.this, "gg", Toast.LENGTH_SHORT).show();

        mHandler.postDelayed(this, 10000);
    }
};

mHandler.post(mRunnable); // 启动计时器

mHandler.removeCallbacks(mRunnable); // 停止计时器
