本文介绍了一个使用Android实现的进度条动态更新示例。通过定时任务的方式，根据不同的进度范围，进度条以不同速率递增，直到完成。示例中还包括了进度条的点击事件及UI布局。

public class ProgressBarTestActivity extends Activity{

private ProgressBar mProgress;
public static int mProgressStatus = 0;
private Handler handler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mProgress = (ProgressBar) findViewById(R.id.ProgressBar01);
mProgress.setOnClickListener(new View.OnClickListener(){
public void onClick(View view) {
ProgressBarTestActivity.mProgressStatus = 0;
Timer timer = new Timer();
timer.schedule(new ReTimerTask(),0,1*1000);

thread.start();
}
});

}

Thread thread = new Thread(new Runnable() {
public void run() {
while (mProgressStatus < 100){
handler.post(new Runnable() {
public void run() {
mProgress.setProgress(mProgressStatus);
}
});
}
}
});

class ReTimerTask extends TimerTask{

@Override
public void run() {
//以下是监测进度到什么位置，如果在75范围内就对进度+5，如果在75----100之间就对进度+1，否则取消此任务
if(ProgressBarTestActivity.mProgressStatus < 75){
ProgressBarTestActivity.mProgressStatus += 5;
Log.i("______ProgressBarTestActivity<75______",""+ProgressBarTestActivity.mProgressStatus);
}else if(ProgressBarTestActivity.mProgressStatus >= 75 && ProgressBarTestActivity.mProgressStatus<100){
ProgressBarTestActivity.mProgressStatus += 1;
Log.i("______ProgressBarTestActivity>=75&&<100______",""+ProgressBarTestActivity.mProgressStatus);
}else if(ProgressBarTestActivity.mProgressStatus >= 100){
cancel();
}
}
}
