兩個布局文件：
1.activity_main.xml，就三個Button
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" ?
? ? xmlns:tools="http://schemas.android.com/tools" ?
? ? android:layout_width="fill_parent" ?
? ? android:layout_height="fill_parent" ?
? ? android:orientation="vertical"> ?
? ??<Button ??
? ? ? ? android:id="@+id/pop_left_btn" ?
? ? ? ? android:layout_width="fill_parent" ?
? ? ? ? android:layout_height="wrap_content" ?
? ? ? ? android:text="@string/pop_left"/> ?
? ? <Button ??
? ? ? ? android:id="@+id/pop_right_btn" ?
? ? ? ? android:layout_width="fill_parent" ?
? ? ? ? android:layout_height="wrap_content" ?
? ? ? ? android:text="@string/pop_right"/> ?
? ? <Button ??
? ? ? ? android:id="@+id/pop_bottom_btn" ?
? ? ? ? android:layout_width="fill_parent" ?
? ? ? ? android:layout_height="wrap_content" ?
? ? ? ? android:text="@string/pop_bottom"/> ?
</LinearLayout> ?
2. pop.xml，也是三個Button，可以自己修改
<?xml version="1.0" encoding="utf-8"?> ?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" ?
? ? android:layout_width="fill_parent" ?
? ? android:layout_height="fill_parent" ?
? ? android:orientation="vertical" > ?
? ? <!-- <LinearLayout ??
? ? ? ? android:layout_width="wrap_content" ?
? ? ? ? android:layout_height="fill_parent" ?
? ? ? ? android:orientation="vertical" ?
? ? ? ? android:background="#ffffff"> --> ?
? ? ? ? <Button android:id="@+id/open" ?
? ? ? ? ? ? android:layout_width="fill_parent" ?
? ? ? ? ? ? android:layout_height="wrap_content" ?
? ? ? ? ? ? android:text="@string/open"/> ?
? ? ? ? <Button android:id="@+id/save" ?
? ? ? ? ? ? android:layout_width="fill_parent" ?
? ? ? ? ? ? android:layout_height="wrap_content" ?
? ? ? ? ? ? android:text="@string/save"/> ?
? ? ? ? <Button android:id="@+id/close" ?
? ? ? ? ? ? android:layout_width="fill_parent" ?
? ? ? ? ? ? android:layout_height="wrap_content" ?
? ? ? ? ? ? android:text="@string/close"/> ?
? ?<!-- ?</LinearLayout> --> ?
</LinearLayout> ?
strings.xml
<string name="pop_left">彈出左側菜單</string> ?
<string name="pop_right">彈出右側菜單</string> ?
<string name="pop_bottom">彈出底部菜單</string> ?
<string name="open">打開</string> ??
<string name="save">保存</string> ??
<string name="close">關閉</string> ??
styles.xml
<style name="AnimationLeftFade"> ?
? ? ? ? <item name="android:windowEnterAnimation">@anim/in_lefttoright</item> ?
? ? ? ? <item name="android:windowExitAnimation">@anim/out_righttoleft</item> ?
?</style> ?
<style name="AnimationRightFade"> ?
? ? ? ? <item name="android:windowEnterAnimation">@anim/in_righttoleft</item> ?
? ? ? ? <item name="android:windowExitAnimation">@anim/out_lefttoright</item> ?
</style> ?
<style name="AnimationBottomFade"> ?
? ? ? ? <item name="android:windowEnterAnimation">@anim/in_bottomtotop</item> ?
? ? ? ? <item name="android:windowExitAnimation">@anim/out_toptobottom</item> ?
</style> ?
左邊彈出菜單動畫文件：
in_lefttoright.xml：從左邊入
<?xml version="1.0" encoding="utf-8"?> ?
<set xmlns:android="http://schemas.android.com/apk/res/android"> ?
? ? <translate ??
? ? ? ? android:fromXDelta="-100%" ?
? ? ? ? android:toXDelta="0" ?
? ? ? ? android:duration="500"/> ?
</set> ?
out_righttoleft.xml：從右邊出
<?xml version="1.0" encoding="utf-8"?> ?
<set xmlns:android="http://schemas.android.com/apk/res/android"> ?
? ? <translate
? ? ? ? android:fromXDelta="0" ?
? ? ? ? android:toXDelta="-100%" ?
? ? ? ? android:duration="500"/> ?
</set> ?
其他動畫文件自己參考寫，就是fromXDelta， fromYDelta， toXDelta和toYDelta使用
