单线程例子

由于sqlite不支持并发,所以我们使用单线程

ExecutorService singleThreadExecutor = Executors.newSingleThreadExecutor();
singleThreadExecutor.execute(new Runnable() {

    @Override
    public void run() {
        // db operetions, u can use handler to send message after
        db.insert(yourTableName, null, value);
        handler.sendEmptyMessage(xx);
    }
});
