BaseRecyclerViewAdapterHelper
介绍:
基于base-adapter-helper开源库的原理,提供了更多的功能。可以让RecyclerView adapter的使用更简单。
运行效果:
使用说明:
下载 apk
-
优化Adapter代码(减少百分之70%代码)
-
添加点击item点击、长按事件、以及item子控件的点击事件
-
添加加载动画(一行代码轻松切换5种默认动画)
-
添加头部、尾部、下拉刷新、上拉加载(感觉又回到ListView时代)
-
设置自定义的加载更多布局
-
添加分组(随心定义分组头部)
-
自定义不同的item类型(简单配置、无需重写额外方法)
-
设置空布局(比Listview的setEmptyView还要好用!)
-
添加拖拽item
先在 build.gradle 的 repositories 添加:
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
然后在dependencies添加:
dependencies {
compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:v1.8.5'
}
如何使用它来创建Adapter?
public class QuickAdapter extends BaseQuickAdapter<Status> {
public QuickAdapter() {
super(R.layout.tweet, DataServer.getSampleData());
}
@Override
protected void convert(BaseViewHolder helper, Status item) {
helper.setText(R.id.tweetName, item.getUserName())
.setText(R.id.tweetText, item.getText())
.setText(R.id.tweetDate, item.getCreatedAt())
.setVisible(R.id.tweetRT, item.isRetweet())
.linkify(R.id.tweetText);
Glide.with(mContext).load(item.getUserAvatar()).crossFade().into((ImageView) helper.getView(R.id.iv));
}
}
如何添加item点击、长按事件
mQuickAdapter.setOnRecyclerViewItemClickListener();
mQuickAdapter.setOnRecyclerViewItemLongClickListener();
新增添加子布局多个控件的点击事件
Adapter
protected void convert(BaseViewHolder helper, Status item) {
helper.setOnClickListener(R.id.tweetAvatar, new OnItemChildClickListener())
.setOnClickListener(R.id.tweetName, new OnItemChildClickListener());
}
Activity
mQuickAdapter.setOnRecyclerViewItemChildClickListener(new BaseQuickAdapter.OnRecyclerViewItemChildClickListener() {
@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
String content = null;
Status status = (Status) adapter.getItem(position);
switch (view.getId()) {
case R.id.tweetAvatar:
content = "img:" + status.getUserAvatar();
break;
case R.id.tweetName:
content = "name:" + status.getUserName();
break;
}
Toast.makeText(AnimationUseActivity.this, content, Toast.LENGTH_LONG).show();
}
});
如何使用它添加动画?
// 一行代码搞定(默认为渐显效果)
quickAdapter.openLoadAnimation();
不喜欢渐显动画可以这样更换
// 默认提供5种方法(渐显、缩放、从下到上,从左到右、从右到左)
quickAdapter.openLoadAnimation(BaseQuickAdapter.ALPHAIN);
还是没你喜欢的,你可以自定义
// 自定义动画如此轻松
quickAdapter.openLoadAnimation(new BaseAnimation() {
@Override
public Animator\[\] getAnimators(View view) {
return new Animator\[\]{
ObjectAnimator.ofFloat(view, "scaleY", 1, 1.1f, 1),
ObjectAnimator.ofFloat(view, "scaleX", 1, 1.1f, 1)
};
}
});
使用它添加头部添加尾部
mQuickAdapter.addHeaderView(getView());
mQuickAdapter.addFooterView(getView());
使用它加载更多
mQuickAdapter.openLoadMore(PAGE_SIZE, true);
mQuickAdapter.setOnLoadMoreListener(new BaseQuickAdapter.RequestLoadMoreListener() {
@Override
public void onLoadMoreRequested() {
mRecyclerView.post(new Runnable() {
@Override
public void run() {
if (mCurrentCounter >= TOTAL_COUNTER) {
mQuickAdapter.notifyDataChangedAfterLoadMore(false);
} else {
mQuickAdapter.notifyDataChangedAfterLoadMore(DataServer.getSampleData(PAGE_SIZE), true);
mCurrentCounter = mQuickAdapter.getItemCount();
}
}
});
}
});
设置自定义加载更多布局
mQuickAdapter.setLoadingView(customView);
使用分组
public class SectionAdapter extends BaseSectionQuickAdapter<MySection> {
public SectionAdapter(int layoutResId, int sectionHeadResId, List data) {
super(layoutResId, sectionHeadResId, data);
}
@Override
protected void convert(BaseViewHolder helper, MySection item) {
helper.setImageUrl(R.id.iv, (String) item.t);
}
@Override
protected void convertHead(BaseViewHolder helper,final MySection item) {
helper.setText(R.id.header, item.header);
else
helper.setOnClickListener(R.id.more, new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context,item.header+"more..",Toast.LENGTH_LONG).show();
}
});
}
如何添加多种类型item?
public class MultipleItemQuickAdapter extends BaseMultiItemQuickAdapter<MultipleItem> {
public MultipleItemQuickAdapter(List data) {
super(data);
addItemType(MultipleItem.TEXT, R.layout.text_view);
addItemType(MultipleItem.IMG, R.layout.image_view);
}
@Override
protected void convert(BaseViewHolder helper, MultipleItem item) {
switch (helper.getItemViewType()) {
case MultipleItem.TEXT:
helper.setImageUrl(R.id.tv, item.getContent());
break;
case MultipleItem.IMG:
helper.setImageUrl(R.id.iv, item.getContent());
break;
}
}
}
使用setEmptyView
mQuickAdapter.setEmptyView(getView());
使用拖拽与滑动删除
OnItemDragListener onItemDragListener = new OnItemDragListener() { @Override
public void onItemDragStart(RecyclerView.ViewHolder viewHolder, int pos){} @Override
public void onItemDragMoving(RecyclerView.ViewHolder source, int from, RecyclerView.ViewHolder target, int to) {} @Override
public void onItemDragEnd(RecyclerView.ViewHolder viewHolder, int pos) {}
}OnItemSwipeListener onItemSwipeListener = new OnItemSwipeListener() { @Override
public void onItemSwipeStart(RecyclerView.ViewHolder viewHolder, int pos) {} @Override
public void clearView(RecyclerView.ViewHolder viewHolder, int pos) {} @Override
public void onItemSwiped(RecyclerView.ViewHolder viewHolder, int pos) {}
};ItemDragAndSwipeCallback itemDragAndSwipeCallback = new ItemDragAndSwipeCallback(mAdapter);ItemTouchHelper itemTouchHelper = new ItemTouchHelper(itemDragAndSwipeCallback);
itemTouchHelper.attachToRecyclerView(mRecyclerView);// 开启拖拽mAdapter.enableDragItem(itemTouchHelper, R.id.textView, true);
mAdapter.setOnItemDragListener(onItemDragListener);// 开启滑动删除mAdapter.enableSwipeItem();
mAdapter.setOnItemSwipeListener(onItemSwipeListener);
