SwipeListView實現QQ消息側滑刪除功能

看到別人實現SwipeListView，說的不清楚，好多細節要注意，作爲菜鳥的我，也是拿來主義。

在 github有這個開源項目https://github.com/47deg/android-swipelistview

好了，我整理好了這些，也不必大家去github下載。點擊此處下載必要源碼。

空說無意，先看一下效果圖。

one,先建立一個工程demo,

two,另外再建立一個包，取名爲com.fortysevendeg.swipelistview

爲什麼取這個名，下面再講

three，把我上傳的文件中的四個Java文件複製到名爲com.fortysevendeg.swipelistview的包中

會發現四個Java的頂部是package com.fortysevendeg.swipelistview;爲了不必要的麻煩這樣去步奏2的包名。

four，把我上傳的文件中的swipelistview__attrs.xml複製到res/values文件夾在

其中要添加

xmlns:swipe="http://schemas.android.com/apk/res-auto"

必需要添加，自定義的SwipeListView因爲添加了，可定義屬性要添加這一句

<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]"
            />

基本屬性如下：

swipeFrontView - Required - front view id. 即ListView Item正常顯示的控件Id，且必須與Item的佈局文件中的控件id一樣
swipeBackView - Required - back view id. 手指滑動時顯示的，隱藏在FrontView後面，且必須與item的佈局文件中控件Id一樣
swipeActionLeft - Optional - left swipe action Default: 'reveal' 左滑的動作，默認reveal，即顯示BackView，還有dismiss,choice會觸發響應的方法。
swipeActionRight - Optional - right swipe action Default: 'reveal' 同上
swipeMode - Gestures to enable or 'none'. Default: 'both' 設置左滑、右滑、都支持
swipeCloseAllItemsWhenMoveList - Close revealed items on list motion. Default: 'true' 當滾動listview時，關閉所有展開的Item，最好不要設置爲false，由於item的複用，false存在一些問題。
swipeOpenOnLongPress - Reveal on long press Default: 'true' 長按時觸發顯示
swipeAnimationTime - item drop animation time. Default: android configuration 動畫時間長度
swipeOffsetLeft - left offset 左偏移量
swipeOffsetRight - right offset 右偏移量

下面是我的demo

activity_main.xml

記得加上這句：xmlns:swipe="http://schemas.android.com/apk/res-auto"

<span style="font-size:14px;"><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:swipe="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.demo.swipelistviewdemo.MainActivity" >

    <com.fortysevendeg.swipelistview.SwipeListView
        android:id="@+id/example_lv_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:listSelector="#00000000"
        swipeActionLeft="reveal"
        swipe:swipeAnimationTime="0"
        swipe:swipeBackView="@+id/back"
        swipe:swipeCloseAllItemsWhenMoveList="true"
        swipe:swipeFrontView="@+id/front"
        swipe:swipeMode="left"
        swipe:swipeOffsetLeft="0dp"
        swipe:swipeOffsetRight="0dp"
        swipe:swipeOpenOnLongPress="false"/>

</RelativeLayout></span>

要注意兩個屬性

swipe:swipeFrontView="@+id/front"

swipe:swipeBackView="@+id/back"

必須與Item的佈局文件中的控件id一樣

swipeActionLeft要最好swipeMode=“left”，屬性要一致，否則，很容易有bug;

list_item.xml佈局

注意前臺佈局，和隱藏佈局的id要與swipe:swipeFrontView="@+id/front"和swipe:swipeBackView="@+id/back"

一致。

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    

    <!-- linearlayout中的佈局是每一項後面隱藏的佈局 -->

    <LinearLayout
        android:id="@+id/back"
        android:layout_width="match_parent"
        android:layout_height="80dp"
        android:background="#eee"
        android:tag="back" >

        <Button
            android:id="@+id/example_row_b_action_2"
            android:layout_width="0dp"
            android:layout_height="60dp"
            android:layout_gravity="center"
            android:layout_marginLeft="10dp"
            android:layout_weight="1"
            android:background="@android:color/holo_purple"
            android:text="刪除" />

        <Button
            android:id="@+id/example_row_b_action_3"
            android:layout_width="0dp"
            android:layout_height="60dp"
            android:layout_gravity="center"
            android:layout_weight="1"
            android:background="@android:color/holo_red_dark"
            android:text="編輯" />
    </LinearLayout>

    <!-- 這裏是前臺顯示的佈局 -->

    <RelativeLayout
        android:id="@+id/front"
        android:layout_width="match_parent"
        android:layout_height="80dp"
        android:background="#ffffff"
        android:orientation="vertical"
        android:tag="front" >

        <TextView
            android:id="@+id/example_row_tv_title"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:textSize="18sp" />
    </RelativeLayout>


</FrameLayout>

         {  
             Log.d("msg", "onChoiceEnded");

         }  
       //滑動時調用已展開
         @Override

             Log.d("msg", "onOpened:" + position + "," + toRight);  
         }  
       //滑動時調用開始關閉
         @Override  
         public void onStartClose(int position, boolean right)  
         {  
             Log.d("msg", "onStartClose:" + position + "," + right);  
         }  
         //滑動時調用開始打開
         @Override  
         public void onStartOpen(int position, int action, boolean right)  
         {  
             Log.d("msg", "onStartOpen:" + position + "," + action + ","  
                     + right);  
             if (closeItem!=position) {
 				mSwipeListView.closeOpenedItems();
 				mSwipeListView.openAnimate(position);
 			}
             
         }  
	}
}

在監聽事件中的這幾個方法中關閉 mSwipeListView.closeOpenedItems();就可以實現QQ側滑效果

  @Override  
         public void onStartOpen(int position, int action, boolean right)  
         {  
             Log.d("msg", "onStartOpen:" + position + "," + action + ","  
                     + right);  
             if (closeItem!=position) {
 				mSwipeListView.closeOpenedItems();
 				mSwipeListView.openAnimate(position);
 			}
             
         }

@Override  
         public void onListChanged()  
         {  
             Log.d("msg", "onListChanged");  
             mSwipeListView.closeOpenedItems();  
         }

@Override  
         public void onChoiceChanged(int position, boolean selected)  
         {  
             Log.d("msg", "onChoiceChanged:" + position + ", " + selected); 
<span style="white-space:pre">				</span>mSwipeListView.closeOpenedItems();
         }
