今天在github上发现一个非常不错的开源项目 SwipeListView，官网地址：https://github.com/47deg/android-swipelistview。
它可以实现ListView的滑动相关的一些效果，例如类似微信 ListView滑动删除效果等等，自己写了一个Demo Mark 一下。
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:swipe="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/background_app" android:orientation="vertical" > <com.fortysevendeg.swipelistview.SwipeListView android:id="@+id/mSwipeListView" android:layout_width="match_parent" android:layout_height="match_parent" android:listSelector="#00000000" swipe:swipeBackView="@+id/back" swipe:swipeCloseAllItemsWhenMoveList="true" swipe:swipeDrawableChecked="@drawable/choice_selected" swipe:swipeDrawableUnchecked="@drawable/choice_unselected" swipe:swipeFrontView="@+id/front" swipe:swipeMode="both" /> </LinearLayout>

细节不多说了，自己可以去看官网文档
XML Usage
If you decide to use SwipeListView as a view, you can define it in your xml layout like this:
<com.fortysevendeg.swipelistview.SwipeListView xmlns:swipe=http://schemas.android.com/apk/res-auto android:id="@+id/example_lv_list" android:listSelector="#00000000" android:layout_width="fill_parent" android:layout_height="wrap_content" swipe:swipeFrontView="@+id/front" swipe:swipeBackView="@+id/back" swipe:swipeActionLeft="[reveal | dismiss]" swipe:swipeActionRight="[reveal | dismiss]" swipe:swipeMode="[none | both | right | left]" swipe:swipeCloseAllItemsWhenMoveList="[true | false]" swipe:swipeOpenOnLongPress="[true | false]" swipe:swipeAnimationTime="[miliseconds]" swipe:swipeOffsetLeft="[dimension]" swipe:swipeOffsetRight="[dimension]" /> swipeFrontView- Required - front view id.swipeBackView- Required - back view id.swipeActionLeft- Optional - left swipe action Default: 'reveal'swipeActionRight- Optional - right swipe action Default: 'reveal'swipeMode- Gestures to enable or 'none'. Default: 'both'swipeCloseAllItemsWhenMoveList- Close revealed items on list motion. Default: 'true'swipeOpenOnLongPress- Reveal on long press Default: 'true'swipeAnimationTime- item drop animation time.
