关于自定义listview，整合下拉刷新上拉加载功能，以及item侧滑功能，并且解决滑动冲突

最近几天公司项目重构，所以没有事，所以来研究一下安卓Litview，这里记下，以防日后查看。

公司项目要求listview能够实现分页加载以及上拉下拉刷新功能，有尝试用过google自己的刷新控件，但是效果不满意，于是选择找三方，在个Github上找到N个DEMO,发现实现方式多样，主要以下两种方式

1，通过添加listview的headview与footview动态设置margin来控制；

2，定义一PullToRefreshLayout用于控制下拉和上拉，要实现的下拉上拉的控件实现自定义借口Pullabule;

方法1比较单调，要实现任何布局都能上拉和下拉故采用方法2；

现在可以看下方法2可以实现的效果

要上下拉的控件实现借口Pullable.java

</pre><pre name="code" class="java">public interface Pullable{/** * 判断是否可以下拉，如果不需要下拉功能可以直接return false *  * @return true如果可以下拉否则返回false */boolean canPullDown();/** * 判断是否可以上拉，如果不需要上拉功能可以直接return false *  * @return true如果可以上拉否则返回false */boolean canPullUp();}

以lisview为例PullableListView.java

public class PullableListView extends ListView implements Pullable{public PullableListView(Context context){super(context);}public PullableListView(Context context, AttributeSet attrs){super(context, attrs);}public PullableListView(Context context, AttributeSet attrs, int defStyle){super(context, attrs, defStyle);}@Overridepublic boolean canPullDown(){if (getCount() == 0){// 没有item的时候也可以下拉刷新return true;} else if (getFirstVisiblePosition() == 0&& getChildAt(0).getTop() >= 0){// 滑到ListView的顶部了return true;} elsereturn false;}@Overridepublic boolean canPullUp(){if (getCount() == 0){// 没有item的时候也可以上拉加载return true;} else if (getLastVisiblePosition() == (getCount() - 1)){// 滑到底部了if (getChildAt(getLastVisiblePosition() - getFirstVisiblePosition()) != null&& getChildAt(getLastVisiblePosition()- getFirstVisiblePosition()).getBottom() <= getMeasuredHeight())return true;}return false;}}

重点来了PullToRefreshLayout.java

public class PullToRefreshLayout extends RelativeLayout {public static final String TAG = "PullToRefreshLayout";// 初始状态public static final int INIT = 0;// 释放刷新public static final int RELEASE_TO_REFRESH = 1;// 正在刷新public static final int REFRESHING = 2;// 释放加载public static final int RELEASE_TO_LOAD = 3;// 正在加载public static final int LOADING = 4;// 操作完毕public static final int DONE = 5;// 锁定public static final int LOCK = 6;// 当前状态private int state = INIT;// 刷新回调接口private OnRefreshListener mListener;// 刷新成功public static final int SUCCEED = 0;// 刷新失败public static final int FAIL =

refreshDist = 200;// 释放加载的距离private float loadmoreDist = 200;private MyTimer timer;// 回滚速度public float MOVE_SPEED = 8;// 第一次执行布局private boolean isLayout = false;// 在刷新过程中滑动操作private boolean isTouch = false;// 手指滑动距离与下拉头的滑动距离比，中间会随正切函数变化private float radio = 2;// 下拉箭头的转180°动画private RotateAnimation rotateAnimation;// 均匀旋转动画private RotateAnimation refreshingAnimation;// 下拉头private View

上面只是上拉加载和下拉刷新的用法，下面我们开始整合侧滑功能，不说话先看效果

整合的代码，只需要改变listview的Adapater,所以请把上个Activity中的内部的Myadapter替换为以下外部类RefeshandSwipeAdapter（此处我写成外部类，是功能需要，放在内部将有bug）

RefeshandSwipeAdapter.java

实现侧滑主要是靠item位置变化，item的xml如下

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:background="@drawable/item_point_bg"    android:orientation="horizontal" >    <RelativeLayout        android:id="@+id/item_left"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="#FFFFFF"        android:paddingBottom="5dp"        android:paddingLeft="10dp"        android:paddingRight="10dp"        android:paddingTop="5dp" >        <ImageView            android:id="@+id/iv_icon"            android:layout_width="50dp"            android:layout_height="50dp"            android:layout_marginRight="5dp"            android:src="@drawable/reading" />        <TextView            android:id="@+id/tv_title"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_toRightOf="@id/iv_icon"            android:textColor="@color/black"            android:textSize="15sp" />        <TextView            android:id="@+id/tv_msg"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_alignBottom="@id/iv_icon"            android:layout_alignLeft="@id/tv_title"            android:singleLine="true"            android:ellipsize="end"            android:textColor="@color/grey" />        <TextView            android:id="@+id/tv_time"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_alignParentRight="true"            android:layout_alignTop="@id/tv_title"            android:textColor="@color/grey" />    </RelativeLayout>    <RelativeLayout        android:id="@+id/item_right"        android:layout_width="wrap_content"        android:layout_height="match_parent"        android:background="@color/right_bg" >        <TextView            android:id="@+id/item_right_txt"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerInParent="true"            android:drawableLeft="@drawable/del_icon_normal"            android:gravity="center"            android:text="删除"            android:textColor="@color/blur_bg" />    </RelativeLayout></LinearLayout>

在博主整合的过程中，出现了滑动冲突，当listview处于最顶部和底部的时候，将会出现卡顿现象，经过仔细思考，决定从PullToRefreshLayout进行优化，将上拉和下拉的状态中添加一个LOCK，用于当侧滑时锁定，以上代码是已经优化过的，不过还有没有其他Bug,暂时还没测出，

博主在完成项目中，也是在csdn上下载过多个类似Demo但是效果都不理想，特别滑动冲突方面，卡顿相当严重，经过自己的研究，完成这个Demo,希望对看到微博的朋友有些帮助
