PopupWindow的布局popwindow.xml
注意3个LinearLayout里必须设置clickable和background，这样当点击上去的时候才会有点击效果。
android:clickable="true"
android:background="@drawable/state_btn_pressed"

<?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="wrap_content"

        android:orientation="horizontal"

        android:id="@+id/layout_main"

        >

        <LinearLayout android:layout_width="fill_parent"

            android:layout_height="wrap_content"

            android:orientation="vertical"

            android:gravity="center_horizontal"

            android:clickable="true"

            android:background="@drawable/state_btn_pressed"

            android:layout_weight=""

            android:id="@+id/btn_0"

            >

            <ImageView android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:scaleType="fitCenter"

                android:src="@drawable/ic_call"

                android:text="电话">

            </TextView>

        </LinearLayout>

        <LinearLayout android:layout_width="fill_parent"

            android:layout_height="wrap_content"

            android:orientation="vertical"

            android:gravity="center_horizontal"

            android:clickable="true"

            android:background="@drawable/state_btn_pressed"

            android:layout_weight=""

            android:id="@+id/btn_1"

            >

                android:src="@drawable/ic_home"

                >

            </ImageView>

            <TextView android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:scaleType="fitCenter"

                android:src="@drawable/ic_sms"

                >

            </ImageView>

            <TextView android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:text="短信"

                >

            </TextView>

        </LinearLayout>

</LinearLayout>

state_btn_pressed.xml，点击的效果：

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true"

        android:drawable="@drawable/bg_btn_pressed"

        android:padding="0dp"/>

</selector>

Android 模仿迅雷的 PopupWindow 出现/消失动画
出现：

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">

    <scale android:fromXScale="0.6" android:toXScale="1.1"

        android:fromYScale="0.6" android:toYScale="1.1" android:pivotX="50%"

        android:pivotY="50%" android:duration="" />

    <scale android:fromXScale="1.0" android:toXScale="0.91"

        android:fromYScale="1.0" android:toYScale="0.91" android:pivotX="50%"

        android:pivotY="50%" android:duration="" android:delay="" />

    <alpha android:interpolator="@android:anim/linear_interpolator"

        android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="" />

</set>

消失：

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">

    <scale android:fromXScale="1.0" android:toXScale="1.25"

        android:fromYScale="1.0" android:toYScale="1.25" android:pivotX="50%"

        android:pivotY="50%" android:duration="" />

    <scale android:fromXScale="1.0" android:toXScale="0.48"

        android:fromYScale="1.0" android:toYScale="0.48" android:pivotX="50%"

        android:pivotY="50%" android:duration="" android:delay="" />

    <alpha android:interpolator="@android:anim/linear_interpolator"

        android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="" />

</set>

最后用下面的 XML 封装：

<?xml version="1.0" encoding="utf-8"?>

<resources>

    <style name="PopupAnimation" parent="android:Animation"

        mce_bogus="">

        <item name="android:windowEnterAnimation">@anim/anim_dialog_show</item>

        <item name="android:windowExitAnimation">@anim/anim_dialog_hide</item>

    </style>

</resources>
