Android UI开发第四十三篇——使用Property Animation实现墨迹天气3.0引导界面及动画实现
前面写过《墨迹天气3.0引导界面及动画实现》,里面完美实现了动画效果,那一篇文章使用的View Animation,这一篇文章使用的Property Animation实现。Property Animation是Android3.0以后新增的动画库。
这篇文章的源代码以及效果在github。
实现墨迹天气向上滑动的viewpager使用的开源库ViewPager-Android。
ViewPager-Android开源库设置app:orientation定义滑动方向。
墨迹天气引导界面共同拥有4个视图,先看一下:(这里引入的图片都是实现后的,截图都是静态图,运行程序看动画效果)。

图三 图四
墨迹天气的引导界面使用的无非是移动、渐变、缩放、转动或者当中几个的组合。
我们介绍当中的部分实现。
1、缩放动画
首先是图一的“极低耗电”使用了一个缩放效果。使用Property Animation实现例如以下:
xml动画文件:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="together" > <objectAnimator
android:duration="1000"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:propertyName="scaleX"
android:valueFrom="1.0"
android:valueTo="1.1"
android:valueType="floatType" >
</objectAnimator>
<objectAnimator
android:duration="1000"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:propertyName="scaleY"
android:valueFrom="1.0"
android:valueTo="1.1"
android:valueType="floatType" >
</objectAnimator> </set>
java使用:
animation1=(AnimatorSet)AnimatorInflater.loadAnimator(PropertyAnimActivity.this,
R.animator.tutorail_rotate);
LinearInterpolator lin = new LinearInterpolator();
animation1.setInterpolator(lin);
t1_icon2.setVisibility(View.VISIBLE); animation1.setTarget(t1_icon2);
animation1.start();
2、移动渐变组合动画
图一中以下的箭头使用了移动渐变组合动画,实现例如以下:
xml文件:
<? xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="together" > <!--
能够包括<objectAnimator>, <valueAnimator>,<set>项
属性:android:ordering=["together" | "sequentially"],子集运行顺序
sequentially Play animations in this set sequentially
together (default) Play animations in this set at the same time.
--> <set
xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="together" >
<objectAnimator
android:duration="1000"
android:propertyName="translationX"
android:repeatCount="infinite"
android:repeatMode="reverse"
android:valueFrom="0"
android:valueTo="0"
android:valueType="floatType" >
</objectAnimator>
<objectAnimator
android:duration="1000"
android:propertyName="translationY"
android:repeatCount="infinite"
android:repeatMode="reverse"
android:valueFrom="-15"
android:valueTo="20"
android:valueType="floatType" >
</objectAnimator>
</set> <objectAnimator
android:duration="1000"
android:propertyName="alpha"
android:repeatCount="infinite"
android:valueFrom="1.0"
android:valueTo="0.3"
android:valueType="floatType" >
</objectAnimator>
<!--
objectAnimator: android:propertyName
对view能够设置一下值:
translationX and translationY:
These properties control where the View is located
as a delta from its left and top coordinates which
are set by its layout container.
rotation, rotationX, and rotationY:
These properties control the rotation
in 2D (rotation property) and 3D around the pivot point.
scaleX and scaleY:
These properties control the 2D scaling of a View around
its pivot point.
pivotX and pivotY:
These properties control the location of the pivot point,
around which the rotation and scaling transforms occur.
By default, the pivot point is located at the center of
the object.
x and y:
These are simple utility properties to describe
the final location of the View in its container,
as a sum of the left and top values and translationX
and translationY values.
alpha:
Represents the alpha transparency on the View.
This value is 1 (opaque) by default, with a value of 0
representing full transparency (not visible). 还能够设置"backgroundColor"等值 android:valueTo
float, int, or color. Required. The value where the animated property ends.
Colors are represented as six digit hexadecimal numbers (for example, #333333). android:valueFrom
float, int, or color. The value where the animated property starts. If not specified,
the animation starts at the value obtained by the property's get method.
Colors are represented as six digit hexadecimal numbers (for example, #333333). android:duration
int. The time in milliseconds of the animation. 300 milliseconds is the default. android:startOffset
int. The amount of milliseconds the animation delays after start() is called. android:repeatCount:反复次数
说明:
infinite:循环运行,
详细正整数表示循环次数 android:repeatMode:反复模式,
说明:
restart:又一次从头開始运行
reverse:反方向运行 android:valueType
Keyword. Do not specify this attribute if the value is a color.
The animation framework automatically handles color values intType: Specifies that the animated values are integers
floatType (default): Specifies that the animated values are floats
--> </set>
Java调用动画资源和前面是一样的,不做过多说明。
3、旋转缩放组合动画
图1中间使用了旋转缩放组合动画,,实现例如以下:
<?xml version="1.0" encoding="utf-8"? >
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="together" > <set
xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="together" >
<objectAnimator
android:duration="800"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:propertyName="scaleX"
android:valueFrom="0.0"
android:valueTo="1.2"
android:valueType="floatType" >
</objectAnimator>
<objectAnimator
android:duration="800"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:propertyName="scaleY"
android:valueFrom="0.0"
android:valueTo="1.2"
android:valueType="floatType" >
</objectAnimator>
</set> <objectAnimator
android:duration="3000"
android:propertyName="rotation"
android:repeatCount="-1"
android:valueFrom="0.0"
android:valueTo="359.0"
android:valueType="floatType" >
</objectAnimator> </set>
Java调用动画资源和前面是一样的,不做过多说明。
4、平移动画
图三很多其它的使用了平移动画,由于要计算位置,没有使用xml资源文件。Java实现:
transAnimationX2=ObjectAnimator.ofFloat(t3_icon2, "translationX", fx1, tx1);
transAnimationX2.setDuration(800);
transAnimationX2.setRepeatCount(Animation.INFINITE);// Animation.INFINITE
transAnimationX2.setRepeatMode(Animation.RESTART);
transAnimationX2.setInterpolator(new LinearInterpolator()); transAnimationY2=ObjectAnimator.ofFloat(t3_icon2, "translationY", fy1, ty1);
transAnimationY2.setDuration(800);
transAnimationY2.setRepeatCount(Animation.INFINITE);// Animation.INFINITE
transAnimationY2.setRepeatMode(Animation.RESTART);
transAnimationY2.setInterpolator(new LinearInterpolator()); PropertyValuesHolder pvhX3 = PropertyValuesHolder.ofFloat("translationX", fx2, tx2);
PropertyValuesHolder pvhY3 = PropertyValuesHolder.ofFloat("translationY", fy2, ty2);
transAnimation3=ObjectAnimator.ofPropertyValuesHolder(t3_icon3, pvhX3, pvhY3);
transAnimation3.setDuration(1200);
transAnimation3.setRepeatCount(Animation.INFINITE);
transAnimation3.setRepeatMode(Animation.RESTART);
transAnimation3.setInterpolator((new LinearInterpolator())); PropertyValuesHolder pvhX4 = PropertyValuesHolder.ofFloat("translationX", fx3, tx3);
PropertyValuesHolder pvhY4 = PropertyValuesHolder.ofFloat("translationY", fy3, ty3);
transAnimation4=ObjectAnimator.ofPropertyValuesHolder(t3_icon4, pvhX4, pvhY4);
transAnimation4.setDuration(1200);
transAnimation4.setRepeatCount(Animation.INFINITE);
transAnimation4.setRepeatMode(Animation.RESTART);
transAnimation4.setInterpolator((new LinearInterpolator())); PropertyValuesHolder pvhX5 = PropertyValuesHolder.ofFloat("translationX", fx4, tx4);
PropertyValuesHolder pvhY5 = PropertyValuesHolder.ofFloat("translationY", fy4, ty4);
transAnimation5=ObjectAnimator.ofPropertyValuesHolder(t3_icon5, pvhX5, pvhY5);
transAnimation5.setDuration(800);
transAnimation5.setRepeatCount(Animation.INFINITE);
transAnimation5.setRepeatMode(Animation.RESTART);
transAnimation5.setInterpolator((new LinearInterpolator())); flag3=true; // 延迟1秒
new Handler() {
@Override
public void dispatchMessage(Message msg) {
// TODO Auto-generated method stub
if(flag3)
super.dispatchMessage(msg);
} public void handleMessage(android.os.Message msg) {
if (msg.what == 1) { t3_icon2.setVisibility(View.VISIBLE);
t3_icon3.setVisibility(View.VISIBLE);
t3_icon4.setVisibility(View.VISIBLE);
t3_icon5.setVisibility(View.VISIBLE); transAnimationX2.start();
transAnimationY2.start(); transAnimation3.start();
transAnimation4.start();
transAnimation5.start(); t3_icon6_animationDrawable.start(); }
};
}.sendEmptyMessageDelayed(1, 1000);// 1秒
这个动画中更重要的是计算初始和结束位置:
view3.getViewTreeObserver().addOnGlobalLayoutListener(
new OnGlobalLayoutListener() { @Override
public void onGlobalLayout() {
// TODO Auto-generated method stub
int h1 = centerLayout.getTop();
int h2 = centerLayout.getBottom();
DensityUtil densityUtil = new DensityUtil(
PropertyAnimActivity.this);
int w = densityUtil.getScreenWidth(); fx1 = t3_icon2.getTop() + t3_icon2.getHeight();
fy1 = -t3_icon2.getTop() - t3_icon2.getHeight();
tx1 = -t3_icon2.getWidth() - t3_icon2.getLeft();
ty1 = t3_icon2.getTop() + t3_icon2.getLeft()
+ t3_icon2.getWidth(); fx2 = t3_icon3.getTop() + t3_icon3.getHeight();
fy2 = -t3_icon3.getTop() - t3_icon3.getHeight();
tx2 = -t3_icon3.getWidth() - t3_icon3.getLeft();
ty2 = t3_icon3.getTop() + t3_icon3.getLeft()
+ t3_icon3.getWidth(); fx3 = w - t3_icon4.getLeft();
fy3 = -(w - t3_icon4.getLeft());
tx3 = -(h2 - h1 - t3_icon4.getTop());
ty3 = h2 - h1 - t3_icon4.getTop(); fx4 = w - t3_icon5.getLeft();
fy4 = -(w - t3_icon5.getLeft());
tx4 = -(h2 - h1 - t3_icon5.getTop());
ty4 = h2 - h1 - t3_icon5.getTop();
}
});
5、循环插值器
第四页动画中重要的使用了CycleInterpolator(循环插值器)
ObjectAnimator objAnim=ObjectAnimator.ofFloat(t4_icon1, "rotation", 0f, 10f);
CycleInterpolator interpolator = new CycleInterpolator(3.0f);
objAnim.setStartDelay(500);
objAnim.setDuration(3000);
objAnim.setRepeatCount(Animation.INFINITE);// Animation.INFINITE
objAnim.setInterpolator(interpolator);
t4_icon1.setPivotX(t4_icon1.getWidth()*0.47f);
t4_icon1.setPivotY(t4_icon1.getHeight()*0.05f);
objAnim.start();
上面基本实现了墨迹天气的动画效果,很多其它请參考代码。
