Anroid Animation总结

安卓动画分为四种 1、TweenAnimation(变换动画) 又包括 AlphaAnimation(渐变动画) ScaleAnimation(缩放动画) TranslateAnimation(平移动画) RotateAnimation(旋转动画)
2、FrameAnimation 帧动画 3、LayoutAnimation 布局动画 4.PropertyAniamtion属性动画
下面总结一下前三种动画的实现：
1、TweenAnimation 有两种实现方式，写res/anim/.xml文件，或者在java代码中实现
AlphaAnimation渐变动画

java代码

loadAnimation = AnimationUtils.loadAnimation(this, R.anim.alpha);
            image.startAnimation(loadAnimation);

scale.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <alpha
        android:duration="1000"
        android:fromAlpha="0.1"
        android:toAlpha="1.0" >
    alpha>

set>

ScaleAnimation(缩放动画)
java代码

Animation loadAnimation = AnimationUtils.loadAnimation(this, R.anim.scale);
image.startAnimation(loadAnimation);

scale.xml文件

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <scale
        android:duration="2000"
        android:fillAfter="false"
        android:fromXScale="0.0"
        android:fromYScale="0.0"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="1.0"
        android:toYScale="1.0" />
set>

TranslateAnimation(平移动画)
java代码

Animation loadAnimation = AnimationUtils .loadAnimation(this, R.anim.translate);
image.startAnimation(loadAnimation);

translation.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="1000"
        android:fromXDelta="10"
        android:fromYDelta="10"
        android:toXDelta="100"
        android:toYDelta="100" />
set>

java代码方式实现

TranslateAnimation translate = new TranslateAnimation(-50, 50,
                    0, 0);
translate.setDuration(1000);
translate.setRepeatCount(Animation.INFINITE);
translate.setRepeatMode(Animation.REVERSE);
image.startAnimation(translate);

RotateAnimation(旋转动画)
java代码

Animation  loadAnimation = AnimationUtils.loadAnimation(this, R.anim.rotate);
image.startAnimation(loadAnimation);

rotate.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <rotate
        android:duration="1000"
        android:fromDegrees="0"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="+360" />
set>

使用Animation的监听实现续播动画

Animation loadAnimation = AnimationUtils
                    .loadAnimation(this, R.anim.translate);
            image.startAnimation(loadAnimation);
            final Animation loadAnimation2 = AnimationUtils.loadAnimation(this,
                    R.anim.rotate);
            loadAnimation.setAnimationListener(new AnimationListener() {

                @Override
                public void onAnimationStart(Animation arg0) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onAnimationRepeat(Animation arg0) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onAnimationEnd(Animation arg0) {
                    // TODO Auto-generated method stub
                    image.startAnimation(loadAnimation2);
                }
            });

续播2 startOffset是开始的时间

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <alpha
        android:duration="3000"
        android:fromAlpha="0.2"
        android:toAlpha="1.0" />
    <alpha
        android:duration="3000"
        android:fromAlpha="1.0"
        android:startOffset="3000"
        android:toAlpha="0.2" />

set>

用java代码实现 一张图片闪烁的效果

AlphaAnimation alphaAnimation = new AlphaAnimation(0.1f, 1.0f);
alphaAnimation.setDuration(100);
alphaAnimation.setRepeatCount(10);
//倒序重复REVERSE  正序重复RESTART
alphaAnimation.setRepeatMode(Animation.REVERSE);
image.startAnimation(alphaAnimation);

从一个Activity跳转到另一个Activity时，第一个Activity缩小，第二个Activity放大的效果

Intent intent=new Intent(MainActivity.this,MainActivity2.class);
startActivity(intent);
overridePendingTransition(R.anim.zoom_in,R.anim.zoom_out);

zoom_in.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator" >

  <scale
        android:duration="1000"
        android:fromXScale="0.1"
        android:fromYScale="0.1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="1.0"
        android:toYScale="1.0" />
  <alpha
        android:duration="1000"
        android:fromAlpha="0"
        android:toAlpha="1.0" />
set>

zoom_out.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:zAdjustment="top" >

    <scale
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromXScale="1.0"
        android:fromYScale="1.0"
        android:pivotX="50%p"
        android:pivotY="50%p"
        android:toXScale="0.1"
        android:toYScale="0.1" />

    <alpha
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromAlpha="1.0"
        android:toAlpha="0" />
set>

FrameAnimation帧动画

image.setImageResource(R.drawable.anim_list);       

anim_list.xml

<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:drawable="@drawable/one"
        android:duration="500"/>
    <item
        android:drawable="@drawable/two"
        android:duration="500"/>
    <item
        android:drawable="@drawable/three"
        android:duration="500"/>
    <item
        android:drawable="@drawable/four"
        android:duration="500"/>
    <item
        android:drawable="@drawable/five"
        android:duration="500"/>
    <item
        android:drawable="@drawable/six"
        android:duration="500"/>

LayoutAnimation

Animation anim=new AlphaAnimation(0.0f,1.0f);
anim.setDuration(1000);
LayoutAnimationController lac=new LayoutAnimationController(anim);
lac.setOrder(LayoutAnimationController.ORDER_NORMAL);//播放顺序
mRecyclerView.setLayoutAnimation(lac);
mRecyclerView.startLayoutAnimation();
mRecyclerView.setAdapter(adapter);
