Property animation

文件位置/res/anitor/filename.xml

In Java: R.animator.filename
In XML: @[package:]animator/filename

语法

<set
<!--选择是一起执行动画还是按照顺序来-->
android:ordering=["together" | "sequentially"]>

<objectAnimator
 <!--图像的动画名称来规定属性比如backgroudcolor-->
    android:propertyName="string"
 <!--指定播放时间-->
    android:duration="int"
 <!--指定从哪里开始具体的要根据你指定的propertyName-->
    android:valueFrom="float | int | color"
 <!--制定从哪里结束具体的要根据你指定的propertyName-->
    android:valueTo="float | int | color"
 <!--比开始偏移多少也可以理解为延时-->
    android:startOffset="int"
 <!--重复次数比如1是重复两次-->
    android:repeatCount="int"
 <!--重复模式-->
    android:repeatMode=["repeat" | "reverse"]
 <!--默认使用floatType建议不要更改-->
    android:valueType=["intType" | "floatType"]/>

<animator
    android:duration="int"
    android:valueFrom="float | int | color"
    android:valueTo="float | int | color"
    android:startOffset="int"
    android:repeatCount="int"
    android:repeatMode=["repeat" | "reverse"]
    android:valueType=["intType" | "floatType"]/>

<set>
    ...
</set>
</set>

一个简单的例子

新建一个res/anitor/test.xml

    <?xml version="1.0" encoding="utf-8"?>
  <set xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="sequentially">
    <!--dd-->
    <objectAnimator
        android:propertyName="rotation"
        android:duration="2000"
        android:repeatCount="1"
        android:repeatMode="reverse"
        android:valueFrom="0"
        android:valueTo="720"/>
    <objectAnimator
        android:propertyName="rotation"
        android:duration="2000"
        android:repeatCount="1"
        android:startOffset="1000"
        android:repeatMode="reverse"
        android:valueFrom="0"
        android:valueTo="720"/>

  </set>

在MainActivity.class中

  btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            AnimatorSet animatorSet =   (AnimatorSet)AnimatorInflater.loadAnimator(MainActivity.this, R.animator.test);
            animatorSet.setTarget(imageView);
            animatorSet.start();

        }
    });

Tween animation

文件存储位置

res/anim/filename.xml
In Java: R.anim.filename
In XML: @[package:]anim/filename

语法

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@[package:]anim/interpolator_resource"
android:shareInterpolator=["true" | "false"] >
 <!--渐变-->
<alpha
    android:fromAlpha="float"
    android:toAlpha="float" />
 <!--缩放-->
<scale
    android:fromXScale="float"
    android:toXScale="float"
    android:fromYScale="float"
    android:toYScale="float"
    android:pivotX="float"
    android:pivotY="float" />
 <!--位置移动-->
<translate
    android:fromXDelta="float"
    android:toXDelta="float"
    android:fromYDelta="float"
    android:toYDelta="float" />
 <!--翻转-->
<rotate
    android:fromDegrees="float"
    android:toDegrees="float"
    android:pivotX="float"
    android:pivotY="float" />
<set>
    ...
</set>
 </set>

一个简单的例子

  <?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="10000"
android:shareInterpolator="true">

<alpha
    android:fromAlpha="0"
    android:toAlpha="100"/>

<translate
    android:fromXDelta="100"
    android:toXDelta="200"/>

<translate
    android:fromXDelta="0"
    android:toXDelta="100"
    android:fromYDelta="0"
    android:toYDelta="100"/>
<rotate
    android:fromDegrees="0"
    android:pivotY="50%"
    android:pivotX="50%"
    android:toDegrees="360"/>

</set>

MainActivity.class

btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Animation animation =   AnimationUtils.loadAnimation(MainActivity.this, R.anim.test);
            imageView.startAnimation(animation);
        }
    });

Frame animation

文件位置

res/drawable/filename.xml
In Java: R.drawable.filename
In XML: @[package:]drawable.filename

语法

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
<!---true代表一次false代表一直-->
android:oneshot=["true" | "false"] >
<item
    android:drawable="@[package:]drawable/drawable_resource_name"
    android:duration="integer" />
</animation-list>

一个简单的例子

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_launcher_background" android:duration="1000"/>
    <item android:drawable="@drawable/ic_launcher_foreground" android:duration="1000"/>
</animation-list>

MainActivity.class

   btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            imageView.setImageResource(R.drawable.test);
            AnimationDrawable animationDrawable =   (AnimationDrawable)imageView.getDrawable();
            animationDrawable.start();
        }
    });
