1.BitmapDrawable
png(最佳)栏笆，jpg(可以接受)放到drawable目錄下，通過R.drawable引用臊泰，也可以通過xml來定義bitmapdrawable蛉加，可以給drawable增加一些屬性

</animation-list>
12.ColorDrawable

<drawable name="blue_color">#0000ff</drawable>
<drawable name="green_color">#00ff00</drawable>
</resources>
13.RippleDrawable (Added in API 21)
在子item上疊加ripple效果
<ripple android:color="#ffff0000">//ripple的顏色
<item android:id="@android:id/mask"
android:drawable="@android:color/white" /> //ripple的遮罩针饥，可以限制ripple的范圍
<item ..> //添加其他item
</ripple>
在view的background設(shè)置android:background="?android:attr/selectableItemBackground" 或者"?android:attr/selectableItemBackgroundBorderless"也可以起到設(shè)置波紋的效果
14.VectorDrawable (Added in API 21)
通過xml來定義矢量圖形，有<vector>來定義
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:height="64dp"
android:width="64dp"
android:viewportHeight="600"
android:viewportWidth="600" >
<group
android:name="rotationGroup"
android:pivotX="300.0"
android:pivotY="300.0"
android:rotation="45.0" >
<path
android:name="v"
android:fillColor="#000000"
android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z" />
</group>
</vector>
15.AnimatedVectorDrawable (Added in API 21)
通過Object Animator來對(duì)VectorDrawable的屬性做動(dòng)畫需频，由<animated-vector>定義
<animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@drawable/vectordrawable" > <- vector drawble
<target
android:name="rotationGroup" <- 屬性
android:animation="@anim/rotation" /> <- object animator的定義文件
<target
android:name="v"
android:animation="@anim/path_morph" />
</animated-vector>
16.AnimatedStateListDrawable (Added in API 21)
StateListDrawble的派生類丁眼，state之間切換時(shí)可以定義動(dòng)畫
<animated-selector
xmlns:android="http://schemas.android.com/apk/res/android">
<!-- provide a different drawable for each state-->
<item android:id="@+id/pressed" android:drawable="@drawable/drawableP"
android:state_pressed="true"/>
<item android:id="@+id/focused" android:drawable="@drawable/drawableF"
android:state_focused="true"/>
<item android:id="@id/default"
android:drawable="@drawable/drawableD"/>
<!-- specify a transition -->
<transition android:fromId="@+id/default" android:toId="@+id/pressed">
<animation-list>
<item android:duration="15" android:drawable="@drawable/dt1"/>
<item android:duration="15" android:drawable="@drawable/dt2"/>
...
</animation-list>
</transition>
...
</animated-selector>
