android - ImageView with rotate xml not rotating

Question

I am using following code,

<ImageView
        android:id="@+id/imgView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:background="@drawable/animate"/>

My animate.xml is,

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:pivotX="50%"
    android:pivotY="50%"
    android:fromDegrees="90"
    android:toDegrees="90"
    android:repeatCount="infinite"
    android:drawable="@drawable/cameras">

And in java to start it,

ImageView imgView=(ImageView)findViewById(R.id.imgView);
              Animation rotation = AnimationUtils.loadAnimation(this, R.drawable.animate);
              imgView.startAnimation(rotation);

But still my ImageView is not rotating, I have seen many examples, but none of them are working.

Answer 1

Try this

    <ImageView
    android:id="@+id/imgView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:src="@drawable/animate"/>

  <?xml version="1.0" encoding="utf-8"?>
  <rotate xmlns:android="http://schemas.android.com/apk/res/android"
   android:fromDegrees="0"
   android:interpolator="@android:anim/linear_interpolator"
   android:pivotX="50%"
   android:pivotY="50%"
   android:repeatCount="infinite"
   android:toDegrees="359"
   android:duration="1000" >
 </rotate>

  ImageView imgView=(ImageView)findViewById(R.id.imgView);
          Animation rotation = AnimationUtils.loadAnimation(this,  R.drawable.animate);
          imgView.startAnimation(rotation);
