我在做一个例子，运动图像由左到右，然后旋转它的自我。 我已经使用AnimationSet尝试，但图像的旋转是不正确的。它的动作在一个周期不是很自我。 如何解决这个问题呢？

I'm making an example that moving an image from left to right then rotate it self. I've tried using AnimationSet but the image rotation isn't correct. It moves in a cycle not it self. How to fix this problem?

我要什么 MainActivity

What I want MainActivity

@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    AnimationSet set = new AnimationSet(true);
    set.setFillAfter(true);
    img_animation = (ImageView) findViewById(R.id.imgBanner);
    Animation rotation = AnimationUtils.loadAnimation(this, R.anim.rotation);
    rotation.setStartOffset(2000);
    rotation.setDuration(2000);
    TranslateAnimation moveLefttoRight = new TranslateAnimation(0, 200, 0, 0);
    moveLefttoRight.setStartOffset(1000);
    moveLefttoRight.setDuration(1000);
    set.addAnimation(moveLefttoRight);
    set.addAnimation(rotation);
    img_animation.startAnimation(set);
}

Rotation.xml

Rotation.xml

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:fromDegrees="0"
    android:interpolator="@android:anim/linear_interpolator"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="90" />

activity_main.xml

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <ImageView
        android:id="@+id/imgBanner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/banner" />

</RelativeLayout>

任何建议与我有益

Any suggestion is helpful with me

推荐答案

请尝试使用这样的：

RotateAnimation anim = new RotateAnimation(0f, 360f,
                    Animation.RELATIVE_TO_SELF, 0.5f,
                    Animation.RELATIVE_TO_SELF, 0.5f);

因此​​，将相对转动本身。 希望这有助于。

So it will rotate relative to itself. Hope this helps.

编辑：

image.clearAnimation();
RotateAnimation anim = new RotateAnimation(30, 360, image.getWidth()/2, image.getHeight()/2);
anim.setFillAfter(true);
anim.setRepeatCount(0);
anim.setDuration(10000);
image.startAnimation(anim); 

我测试了这个在演示应用程序。它的工作太棒了。希望这可以帮助你：）

I tested this one in demo application. Its working great. Hope this helps you :)
