先上效果图
可以采用自定义TextView的方式去实现，也可才用定时更新文字显示，思路是让TextView每隔一秒显示以一个字符串（并非每一秒多出来一个汉字），那么就简单了，可以开启一个线程，那么线程主要方法如下：
public static void startTv(final int n) { new Thread( new Runnable() { @Override public void run() { try { final String stv = s.substring(0, n);//截取要填充的字符串 tv.post(new Runnable() { @Override public void run() { tv.setText(stv); } }); Thread.sleep(time);//休息片刻 nn = n + 1;//n+1；多截取一个 if (nn <= length) {//如果还有汉字，那么继续开启线程，相当于递归的感觉 startTv(nn); } } catch (InterruptedException e) { e.printStackTrace(); } } } ).start(); } 完整代码如下：
1.Activity
public class TiaoZiActivity extends Activity { private TextView textView; private String s = "天生我才必有用，千金散盡還福來--李白\n你挑著但，我騎著馬--唐僧\n年后打蓝思科技卡死了减肥的 kjdsfkjsjkdsfj kjdflskjklfjsljdflsjkldfjsljdflsjdfkl";; private TiaoZiUtil tiaoziUtil; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_tiaozi); textView = ((TextView) findViewById(R.id.tv_text)); tiaoziUtil = new TiaoZiUtil(textView, s, 100);//调用构造方法，直接开启 } @Override protected void onDestroy() { super.onDestroy(); } } 2.工具类
public class TiaoZiUtil { private static TextView tv; private static String s; private static int length; private static long time; static int n = 0; private static int nn; public TiaoZiUtil(TextView tv, String s, long time) { this.tv = tv;//textview this.s = s;//字符串 this.time = time;//间隔时间 this.length = s.length(); startTv(n);//开启线程 } public static void startTv(final int n) { new Thread( new Runnable() { @Override public void run() { try { final String stv = s.substring(0, n);//截取要填充的字符串 tv.post(new Runnable() { @Override public void run() { tv.setText(stv); } }); Thread.sleep(time);//休息片刻 nn = n + 1;//n+1；多截取一个 if (nn <= length) {//如果还有汉字，那么继续开启线程，相当于递归的感觉 startTv(nn); } } catch (InterruptedException e) { e.printStackTrace(); } } } ).start(); } } 3.布局文件
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/tv_text" android:layout_width="match_parent" android:layout_height="200dp" /> <TextView android:id="@+id/mytext" android:layout_width="match_parent" android:layout_height="200dp" /> </LinearLayout>
