Android使用动画设置ProgressBar进度的方法

需求场景：当我们在使用ProgressBar的时候，希望有进度加载的效果，此时我们传统的做法是使用Thread线程来实现，下面我们用属性动画来实现，简单粗暴。。哈哈哈

布局文件：

Activity:

public class MainActivity extends AppCompatActivity {

 private ProgressBar mProgressBar;
 TextView mtv_bar;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  mProgressBar = (ProgressBar) findViewById(R.id.bar);
  mtv_bar = (TextView) findViewById(R.id.tv_bar);
  setAnimation(mProgressBar, 100);
 }

 private void setAnimation(final ProgressBar view, final int mProgressBar) {
  ValueAnimator animator = ValueAnimator.ofInt(0, mProgressBar).setDuration(5000);

  animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
   @Override
   public void onAnimationUpdate(ValueAnimator valueAnimator) {
    view.setProgress((int) valueAnimator.getAnimatedValue());
   }
  });
  animator.start();
 }


 private void setTvAnimation(final TextView view, final int mProgressBar) {
  ValueAnimator animator = ValueAnimator.ofInt(0, mProgressBar).setDuration(5000);

  animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
   @Override
   public void onAnimationUpdate(ValueAnimator valueAnimator) {
    view.setText(String.valueOf(valueAnimator.getAnimatedValue()));
   }
  });
  animator.start();
 }

 public void show(View view) {
  setAnimation(mProgressBar, 100);

 }


 public void tvshow(View view){
  setTvAnimation(mtv_bar,240);
 }
}

效果图：
