    首先，创建一个框架布局，如下所示
  
  
  
   <pre>
 <code>
 <FrameLayout
 android:layout_width="match_parent"
 android:layout_height="wrap_content">

</FrameLayout>

</code>
 </pre>
  
  
  
    然后创建一个文件
     <code>
 progress_bar_style.xml
 </code>
     把它放到你的drawable文件夹中
  
  
    的内容
     <code>
 progress_bar_style.xml
 </code>
     将会跟随
  
   <pre>
 <code>
 <?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

</layer-list>

</code>
 </pre>
  
    以下是您将如何在activity / fragment中实现
  
   <pre>
 <code>
 public class MainActivity extends AppCompatActivity {

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

final ProgressBar progressBar = (ProgressBar) findViewById(R.id.progress_bar);

final ObjectAnimator objectAnimator = ObjectAnimator.ofInt(progressBar, "progress",
                progressBar.getProgress(), 100).setDuration(2000);

objectAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
            @Override
            public void onAnimationUpdate(ValueAnimator valueAnimator) {
                int progress = (int) valueAnimator.getAnimatedValue();
                progressBar.setProgress(progress);
            }
        });

TextView btn = (TextView) findViewById(R.id.text_view_button);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                objectAnimator.start();
            }
        });
    }
}

</code>
 </pre>
