如何创建一个在几秒钟后自动更改文本的textView

Question

我试图创建一个包含我输入的提示的textView。这些提示将存储在sting Array中，如下所示。如何让这个字符串数组中的项目在几秒钟后更改

    </string-array>
<string-array >
    <item> Use low energy compact fluorescent lamps as replacements for traditional incandescent lamps.</item>
   <item >Ensure that thermostats for appliances are effective and set at moderate levels.</item>
    <item >Install low-flow shower heads and faucet aerators to reduce water usage and its associated energy for heating></item>
</string-array>

Answer 1

试试这段代码 -

    final String[] tipsArray = getResources().getStringArray(R.array.tips); 

    final Handler tipsHanlder = new Handler();
    Runnable tipsRunnable = new Runnable() {
        @Override
        public void run() 
        {
            int tipPosition = 0;
            //set number of tip(randon/another way)
            tipsTextView.setText(tipsArray[tipPosition]);
            tipsHanlder.postDelayed(this, 5000);
        }
    };
    tipsHanlder.post(tipsRunnable);

您需要提供基于Randon Generator或其他方法的小费编号。

P.S为您的String数组提供XML中的名称。
