Android进度条自动前进效果的实现代码

final Timer timer = new Timer();
  timer.schedule(new TimerTask() {
   @Override
   public void run() {
    runOnUiThread(new Runnable() {
     @Override
     public void run() {
      proes++;
      bar1.setProgress(proes);  //进度条进度
     }
    });
   }
  },100,100); //间隔时间（单位为毫秒）

int proes = 0; //进度条进度值
 ProgressBar bar1;
 Button but1;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  bar1 = findViewById(R.id.pro1);
  but1 = findViewById(R.id.but1);

  final Timer timer = new Timer();
  timer.schedule(new TimerTask() {
   @Override
   public void run() {
    runOnUiThread(new Runnable() {
     @Override
     public void run() {
      proes++; //增加进度值
      if(proes==100){
      	timer.cancel(); //当proes到最大值时停止增加
      }else{
      	bar1.setProgress(proes); // proes当前进度
      }
     }
    });
   }
  },100,100); //间隔时间（单位为毫秒）
 }
