十秒钟更新完ProgressBar

//注意：//在xml文件中//style="@android:style/Widget.ProgressBar.Horizontal"采用系统自带的样式1 main.xml文件如下<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >       <ProgressBar         android:id="@+id/progressBar"        android:layout_width="wrap_content"        android:layout_height="30dip"        android:visibility="visible"        style="@android:style/Widget.ProgressBar.Horizontal"    /></LinearLayout>2 Activity如下package cn.com;import android.app.Activity;import android.os.Bundle;import android.widget.ProgressBar;public class TestProgressBarActivity extends Activity {private ProgressBar progressBar = null;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);progressBar = (ProgressBar) findViewById(R.id.progressBar);// 从这到下是关键Thread thread = new Thread(new Runnable() {@Overridepublic void run() {int progressBarMax = progressBar.getMax();//得到progressBar的最大刻度try {while (progressBarMax != progressBar.getProgress()) {int everyProgress = progressBarMax / 10;//progressBar的最大刻度细分为十份int currentprogress = progressBar.getProgress();//得到当前刻度progressBar.setProgress(currentprogress + everyProgress);//设置更新后的刻度Thread.sleep(1000);//线程睡眠一秒}} catch (InterruptedException e) {e.printStackTrace();}}});thread.start();//开启线程.关键结束}}
