Alpha

1.alpha改变view的透明度的动画
2.基本属性：
　　duration="5000" 渐变时间
　　fromAlpha="1"  起始时的透明度 1为不透明
　　toAlpha="0"    结束时透明度   0为透明
3.java 
 AlphaAnimation anim=new AlphaAnimation(1, 0);
 anim.setDuration(5000);
 v.startAnimation(anim);

　4.xml

 

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="5000"
    android:fromAlpha="1"
    android:toAlpha="0" >
</alpha>

 

5.xml 启动

 Animation anim = AnimationUtils.loadAnimation(this,R.anim.alpha_first);
 v.startAnimation(anim);

6.Activity 转场动画 /anim

 alpha_in

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:fromAlpha="0"
    android:toAlpha="1" >
</alpha>

alpha_out

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:fromAlpha="1"
    android:toAlpha="0" >
</alpha>

java:

Intent it=new Intent(this,Alpha2Activity.class);
startActivity(it);
overridePendingTransition(R.anim.alpha_in, R.anim.alpha_out);

rotate

1.旋转动画

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="5000"
    android:fromDegrees="1"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="180" >
</rotate>

 

android:pivotX="50%"
android:pivotY="50%"  旋转中心点  view的中信
android:fromDegrees="1"起始时view的角度
android:toDegrees="180" 旋转结束后的角度
选择角度为正时是顺时针旋转，为负时则是逆时针旋转。
2.java:
        RotateAnimation anim=new RotateAnimation(0, 90);
        anim.setDuration(5000);
        v.startAnimation(anim);

3.xml

  Animation anim = AnimationUtils.loadAnimation(this, R.anim.rotate_frist);
 v.startAnimation(anim);

scale

1.缩放动画

<?xml version="1.0" encoding="utf-8"?>
<scale xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="5000"
    android:fromXScale="1"
    android:fromYScale="1"
    android:repeatCount="infinite"
    android:repeatMode="reverse"
    android:toXScale="3"
    android:toYScale="1" >
</scale>

2.java

     //缩放动画 x--1变成0.3  y变成2 放大一倍
        ScaleAnimation anim=new ScaleAnimation(1, 0.3f, 1, 2);
        //时长

<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="5000"
    android:fromXDelta="1"
    android:fromYDelta="1"
    android:interpolator="@android:anim/bounce_interpolator"
    android:toXDelta="1"
    android:fillAfter="true"   
    android:toYDelta="300" >
</translate>
android:interpolator="@android:anim/bounce_interpolator"  // 动画执行速率
android:fillAfter="true"   动画结束时，停留在最后位置

 

2.转场动画

 Intent it=new Intent(this,Alpha2Activity.class);
 startActivity(it);
overridePendingTransition(R.anim.translate_in, R.anim.translate_out);






3.java


 




        /*
         * 300:x方向移动的距离
         */
        TranslateAnimation anim=new TranslateAnimation(1, 300, 1, 1);
        anim.setDuration(5000);
        v.startAnimation(anim);






4.xml




//加载xml
        Animation anim = AnimationUtils.loadAnimation(this, R.anim.translate_first);
        v.startAnimation(anim);




set动画集


1.java




  AlphaAnimation a=new AlphaAnimation(1, 0);
 RotateAnimation b=new RotateAnimation(0, -180);
//动画集:旋转的同时淡出
 AnimationSet set=new AnimationSet(true);
 set.addAnimation(a);
 set.addAnimation(b);
 set.setDuration(5000);
v.startAnimation(set);




 


2.xml




  Animation anim = AnimationUtils.loadAnimation(this, R.anim.set_first);
 v.startAnimation(anim);






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

        android:fromYDelta="1"
        android:toXDelta="200"
        android:toYDelta="300" >
    </translate>
</set>




3.activity转场


 


set_in




<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000" >
    <scale
        android:fromXScale="0"
        android:fromYScale="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="1"
        android:toYScale="1" />
    <alpha
        android:fromAlpha="0"
        android:toAlpha="1" />
</set>




set_out




<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000" >
    <!-- 缩小淡出 -->
    <scale
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="0"
        android:toYScale="0" />
    <alpha
        android:fromAlpha="1"
        android:toAlpha="0" />
</set>






  Intent it=new Intent(this,Alpha2Activity.class);
  startActivity(it);
  overridePendingTransition(R.anim.set_in, R.anim.set_out);




frame


由多张图片循环播放形成的动画


1.drawable/文件 多张图片




<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:drawable="@drawable/loading_0"
        android:duration="100"/>
    <item
        android:drawable="@drawable/loading_1"
        android:duration="100"/>
    <item
        android:drawable="@drawable/loading_2"
        android:duration="100"/>
    <item
        android:drawable="@drawable/loading_3"
        android:duration="100"/>
    <item
        android:drawable="@drawable/loading_4"
        android:duration="100"/>
    <item
        android:drawable="@drawable/loading_5"
        android:duration="100"/>
    <item
        android:drawable="@drawable/loading_6"
        android:duration="100"/>
    <item
        android:drawable="@drawable/loading_7"
        android:duration="100"/>
</animation-list>




2.image中利用




 <ImageView
        android:id="@+id/imageView1"
        android:layout_width="67dp"
        android:layout_height="54dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:background="@drawable/frame_first"
      />




3.java




 ImageView mv=(ImageView) findViewById(R.id.imageView1);
 AnimationDrawable drawable = (AnimationDrawable) mv.getBackground();
 drawable.start();




property


1.补间动画(view动画)的变换只是假象,view的属性值没有发生任何变化，是android操作系统
 通过重新绘制实现的
 属性动画:
 通过改变属性值完成的动画


2.translated对比




 TranslateAnimation a=new TranslateAnimation(1, 300, 1, 1);
 a.setDuration(3000);
 a.setFillAfter(true);
 v.startAnimation(a);






 ObjectAnimator.ofFloat(v, "TranslationY",200).setDuration(2000).start();




在X,Y方向移动，移动后translate无法点击，属性动画依然可以相应点击事件


 


3.监听




   ObjectAnimator anim = ObjectAnimator.ofFloat(v, View.ROTATION_Y, 0,90,180);
        anim.setDuration(5000);
        anim.start();
        //添加监听器
        anim.addListener(new AnimatorListenerAdapter() {
            @Override
            public void onAnimationEnd(Animator animation) {

                super.onAnimationEnd(animation);
            }
        });
    }




4.动画集




        AnimatorSet s=new AnimatorSet();
        ObjectAnimator a = ObjectAnimator.ofFloat(v, View.ALPHA, 1,0);
        ObjectAnimator b = ObjectAnimator.ofFloat(v, View.ROTATION, 1,-90,180,360);
        s.setDuration(5000);
        s.playTogether(a,b);
        s.start();




5.xml  animator/文件




  Animator anim = AnimatorInflater.loadAnimator(this,R.animator.property_first);
        //指定动画作用的对象
 anim.setTarget(v);
        //启动
anim.start();




6.java




        /*
         * v:动画作用的view对象
         * View.TRANSLATION_X：被改变值的属性
         * 第三个参数:属性取值的范围
         */
        ObjectAnimator anim = ObjectAnimator.ofFloat(v, View.TRANSLATION_X,1,20,1,-20,1);
        anim.setDuration(300);
        anim.start();
