微調控制器一個在另一個在android中

Question

我想要在我的android項目中設計和動畫。我不知道如何設計這個。我希望外環順時針旋轉，另一個反時鐘方向明智。我甚至不知道如何創建2個這樣的環。請幫我解決這個問題。

Answer 1

試試這個：

XML文件：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical"> 

    <ImageView 
     android:id="@+id/main_imageRight" 
     android:layout_width="550dp" 
     android:layout_height="550dp" 
     android:src="@drawable/ic_cached_black_24dp" 
     android:layout_marginBottom="104dp" 
     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" /> 

    <ImageView 
     android:id="@+id/main_imageLeft" 
     android:layout_width="200dp" 
     android:layout_height="200dp" 
     android:src="@drawable/ic_cached_black_24dp" 
     android:layout_marginTop="139dp" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" /> 


</RelativeLayout> 

動畫文件：

1. left_circle.xml

<?xml version="1.0" encoding="utf-8"?> <rotate 
xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromDegrees="0" 
    android:pivotX="50%" 
    android:pivotY="50%" 
    android:repeatCount="infinite" 
    android:toDegrees="360" /> 

right_circle.xml

<?xml version="1.0" encoding="utf-8"?> 
<rotate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromDegrees="360" 
    android:pivotX="50%" 
    android:pivotY="50%" 
    android:repeatCount="infinite" 
    android:toDegrees="0" /> 

的Java文件：

 mLLLeft = (ImageView) findViewById(R.id.main_imageLeft); 
     mImageRight = (ImageView) findViewById(R.id.main_imageRight); 

     Animation animRight = AnimationUtils.loadAnimation(this,R.anim.right_circle); 
     animRight.setDuration(5000); 
     mImageRight.startAnimation(animRight); 

     Animation animLeft = AnimationUtils.loadAnimation(this,R.anim.left_circle); 
     animLeft.setDuration(5000); 
     mLLLeft.startAnimation(animLeft); 

Answer 2

嘗試這種方式，它的工作對我來說

<RelativeLayout 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"> 

    <ProgressBar 
      android:id="@+id/progres" 
      android:layout_width="70dp" 
      android:layout_height="70dp" 
      android:indeterminateDrawable="@drawable/clockwise" /> 


    <ProgressBar 
      android:id="@+id/progres1" 
      android:layout_width="100dp" 
      android:layout_height="100dp" 
      android:indeterminateDrawable="@drawable/anti_clockwise" /> 

</RelativeLayout> 

clockwise.xml

<?xml version="1.0" encoding="utf-8"?> 
<rotate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromDegrees="0" 
    android:pivotX="50%" 
    android:pivotY="50%" 
    android:toDegrees="360" > 

    <shape 
     android:innerRadiusRatio="3" 
     android:shape="ring" 
     android:thicknessRatio="30" 
     android:useLevel="false" > 
     <size 
      android:height="76dip" 
      android:width="76dip" /> 

     <gradient 
      android:angle="0" 
      android:endColor="@color/Orange" 
      android:startColor="@color/transparent" 
      android:type="sweep" 
      android:useLevel="false" /> 
    </shape> 

</rotate> 

anti_clockwise.xml

<?xml version="1.0" encoding="utf-8"?> 
<rotate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromDegrees="360" 
    android:pivotX="50%" 
    android:pivotY="50%" 
    android:toDegrees="0" > 

    <shape 
     android:innerRadiusRatio="3" 
     android:shape="ring" 
     android:thicknessRatio="30" 
     android:useLevel="false" > 
     <size 
      android:height="76dip" 
      android:width="76dip" /> 

     <gradient 
      android:angle="0" 
      android:endColor="@color/Orange" 
      android:startColor="@color/transparent" 
      android:type="sweep" 
      android:useLevel="false" /> 
    </shape> 

</rotate>
