Android ListView实现上拉加载下拉刷新和滑动删除功能

最近项目需要用到可以滑动删除并且带有上拉加载下拉刷新的Listview,查阅了一些资料,大多都是在SwipeMenuListView的基础上去添加头部和底部View,来扩展上拉加载和下拉刷新的功能,不过需要手动的去绘制UI及处理一些动画效果.用起来也不是特别方便.刚好项目中用到PulltorefreshLibrary库,就尝试着扩展了一个PullToRefreshSwipeMenuListView类来实现需求.先看一下效果:

实现步骤

一、组合Pulltorefresh与SwipeMenuListView

PulltorefreshLibrary库中包含很多种可以上拉加载下拉刷新的控件,经常用到的比如PullToRefreshListView,PullToRefreshGridView,PullToRefreshScrollView,它们的实现方式类似,本质上是在控件外部添加父布局,父布局中去添加控件的头部和底部View,来实现上拉加载下拉刷新的功能,所以扩展性很强.照猫画虎,copy一份PullToRefreshListView,对他做一些处理.

 protected ListView createListView(Context context, AttributeSet attrs) {
 final ListView lv;
 if (VERSION.SDK_INT >= VERSION_CODES.GINGERBREAD) {
  lv = new InternalListViewSDK9(context, attrs);
 } else {
  lv = new InternalListView(context, attrs);
 }
 return lv;
 }

找到这部分代码,简单的做下修改:

 protected SwipeMenuListView createListView(Context context, AttributeSet attrs) {
 final SwipeMenuListView lv;
 lv = new SwipeMenuListView(context, attrs);
 return lv;
 }

为什么要copy一份PullToRefreshListView而不是其他的呢?因为SwipeMenuListView是继承自ListView的(看名字就可以发现),修改起来比较方便.为什么要修改这部分代码呢?往下看.找一下引用这部分代码的地方:

 @Override
 protected ListView createRefreshableView(Context context, AttributeSet attrs) {
 ListView lv = createListView(context, attrs);
 // Set it to this so it can be used in ListActivity/ListFragment
 lv.setId(android.R.id.list);
 return lv;
 }

是继承父类实现的方法,打开父类的该方法:

 /**
 * This is implemented by derived classes to return the created View. If you
 * need to use a custom View (such as a custom ListView), override this
 * method and return an instance of your custom class.
 * 

 * Be sure to set the ID of the view in this method, especially if you're
 * using a ListActivity or ListFragment.
 *
 * @param context Context to create view with
 * @param attrs AttributeSet from wrapped class. Means that anything you
 *  include in the XML layout declaration will be routed to the
 *  created View
 * @return New instance of the Refreshable View
 */
 protected abstract T createRefreshableView(Context context, AttributeSet attrs);

看一下注释,大概的意思是说,如果需要一个自定义的上拉加载下拉刷新View,可以返回该自定义View.并且返回值是T,一个泛型,说的很明白.看一下这个方法的引用mRefreshableView = createRefreshableView(context, attrs);看命名就知道,这个方法最终返回的是需要上拉加载下拉刷新功能的View.

感觉差不多可以了,来试一下,看一下效果:

好像效果不是很理想,有很多问题,比如滑动删除的时候可以上拉下拉,上拉时没有底部View.接下来来解决这些问题.

二、解决滑动冲突及相关问题

先来解决为什么没有底部View的问题,看一下copy过来修改过的PullToRefreshSwipeMenuListView类和PullToRefreshListView类,对比一下到底有什么区别,使得PullToRefreshSwipeMenuListView没有底部View,在PullToRefreshSwipeMenuListView中只修改了一个部分,就是把之前返回的InternalListView替换成了SwipeMenuListView,显然问题出现在InternalListView上,查看一下InternalListView(很容易找,是个内部类),可以看到这部分代码:

 @Override
 public void setAdapter(ListAdapter adapter) {
  // Add the Footer View at the last possible moment
  if (null != mLvFooterLoadingFrame && !mAddedLvFooter) {
  addFooterView(mLvFooterLoadingFrame, null, false);
  mAddedLvFooter = true;
  }

  super.setAdapter(adapter);
 }

底部View是在InternalListView调用setAdapter方法时添加上的,那头部View呢?查找一下,找到如下代码:

 @Override
 protected void handleStyledAttributes(TypedArray a) {
 super.handleStyledAttributes(a);

 mListViewExtrasEnabled = a.getBoolean(com.handmark.pulltorefresh.library.R.styleable.PullToRefresh_ptrListViewExtrasEnabled, true);

 if (mListViewExtrasEnabled) {
  final FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
   FrameLayout.LayoutParams.WRAP_CONTENT, Gravity.CENTER_HORIZONTAL);

  // Create Loading Views ready for use later
  FrameLayout frame = new FrameLayout(getContext());
  mHeaderLoadingView = createLoadingLayout(getContext(), Mode.PULL_FROM_START, a);
  mHeaderLoadingView.setVisibility(View.GONE);
  // FrameLayout添加头View 
  frame.addView(mHeaderLoadingView, lp);
  // 添加头部View
  mRefreshableView.addHeaderView(frame, null, false);

  mLvFooterLoadingFrame = new FrameLayout(getContext());
  mFooterLoadingView = createLoadingLayout(getContext(), Mode.PULL_FROM_END, a);
  mFooterLoadingView.setVisibility(View.GONE);
  // FrameLayout添加底部View 
  mLvFooterLoadingFrame.addView(mFooterLoadingView, lp);
  // 添加底部View
  ...
  /**
  * If the value for Scrolling While Refreshing hasn't been
  * explicitly set via XML, enable Scrolling While Refreshing.
  */
  if (!a.hasValue(com.handmark.pulltorefresh.library.R.styleable.PullToRefresh_ptrScrollingWhileRefreshingEnabled)) {
  setScrollingWhileRefreshingEnabled(true);
  }
 }
 }

发现头部是在初始化的时候被添加上,而底部并没有添加(代码中…的部分),InternalListView在setAdapter方法中,添加上了底部,SwipeMenuListView中并没有相关的处理,所以在…处添加代码
mRefreshableView.addFooterView(mLvFooterLoadingFrame, null, false);把底部加上,之前发现的没有底部的问题就解决了(当然也可以仿照InternalListView去修改一下SwipeMenuListView,不过比较麻烦,这里就不去做了)

接下来处理一下滑动删除时,可以进行上拉下拉操作的问题,很明显是滑动冲突的问题,想一下,当滑动删除时,不希望进行上拉下拉操作,而PullToRefreshSwipeMenuListView本身是一个ViewGroup,所以当滑动删除时,屏蔽掉父布局的滑动事件就可以了,打开SwipeMenuListView,在滑动事件中做一下处理即可:

 case MotionEvent.ACTION_MOVE:
  float dy = Math.abs((ev.getY() - mDownY));
  float dx = Math.abs((ev.getX() - mDownX));
  if (mTouchState == TOUCH_STATE_X) {
   if (mTouchView != null) {
   mTouchView.onSwipe(ev);
   }
   getSelector().setState(new int[]{0});
   ev.setAction(MotionEvent.ACTION_CANCEL);
   super.onTouchEvent(ev);
   // 处理滑动冲突,当处于滑动删除状态时,请求父布局不处理滑动事件
   requestDisallowInterceptTouchEvent(true);
   return true;
  } else if (mTouchState == TOUCH_STATE_NONE) {
   if (Math.abs(dy) > MAX_Y) {
   mTouchState = TOUCH_STATE_Y;
   } else if (dx > MAX_X) {
   mTouchState = TOUCH_STATE_X;
   if (mOnSwipeListener != null) {
    mOnSwipeListener.onSwipeStart(mTouchPosition);
   }
   }
  }
  break;

很简单,就不多做说明了,不太清楚点击事件分发的童鞋,可以去查阅一下材料,这样一个带有上拉加载下拉刷新可滑动删除的ListView就基本完工了.
