<code class="hljs sql has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">ViewPropertyAnimator animator = view.animate();     animator.translationX(50).rotationBy(-90).rotation(90).setDuration(1000).<span class="hljs-operator" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">start</span>();</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

五、关系分析

多个动画属性（PropertyValues）构成一个动画对象（ObjectAnimator），多个动画对象（ObjectAnimator）合成一个组合动画（AnimatorSet）

六、动画分析

<code class="hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//在属性动画中新增的动画效果有以下几种</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

<code class="hljs glsl has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>）translationX 和 translationY：这两个属性控制了View所处的位置，它们的值是由<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">layout</span>容器设置的，是相对于坐标原点（<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span>，<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span> 左上角）的一个偏移量。<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2</span>）rotation, rotationX 和 rotationY：控制View绕着轴点（pivotX和pivotY）旋转。<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">3</span>）scaleX 和 scaleY：控制View基于pivotX和pivotY的缩放。<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">4</span>）pivotX 和 pivotY：旋转的轴点和缩放的基准点，默认是View的中心点。<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">5</span>）x 和 y：描述了view在其父容器中的最终位置，是左上角左标和偏移量（translationX，translationY）的和。<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">6</span>）aplha：透明度，<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span> 是完全不透明，<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span> 是完全透明。</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

七、彩蛋

<code class="hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">修改view的背景色</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

八、放大招了

<code class="hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//属性动画不止可以应用于View，还可以应用于任何对象。</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

看到上面view变形的时候字体也变了，好不舒服有没有？属性动画的亮点来啦，可以只更改width！

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">ObjectAnimator<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.ofInt</span>(view, <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"width"</span>, <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">800</span>)<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.setDuration</span>(<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">5000</span>)<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.start</span>()<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

Tip:

为了在各种安卓版本上使用属性动画，你需要采用NineOldAndroids。

Property Animation属性动画，还用补间动画你就out了
