publicclass ProgressActivity extends Activity { 
ProgressBar pb = null;
TextView txtProgress;
Handler handler = new Handler();
@Override
publicvoid onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.out.println("主题=" + getTheme() + "");
pb = (ProgressBar) findViewById(R.id.pbPic);
Button btnStart = (Button) findViewById(R.id.btStart);//按钮
txtProgress = (TextView) findViewById(R.id.txtProgress);//显示进度
btnStart.setOnClickListener(new OnClickListener() {//按钮点击事件
publicvoid onClick(View v) {
new Thread(new Runnable() {//创建并启动线程，使用线程执行模拟的任务
publicvoid run() {
for (inti = 0; i <100; i++) { //循环100遍
try {
handler.post(new Runnable() { //更新界面的数据
publicvoid run() {
pb.incrementProgressBy(1);//增加进度
txtProgress.setText(pb.getProgress() + "%");//显示完成的进度
}
});
Thread.sleep(100);
} catch (InterruptedException e) {
}
}

}).start();
