是什么
BaseRecyclerViewAdapterHelper是一个强大并且灵活的RecyclerViewAdapter
能做什么
效果图
配置使用
在 build.gradle 的 repositories 添加:
allprojects {
repositories {
maven { url "https://jitpack.io" }
}
}
然后增加dependencies
dependencies {
compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:v1.5.8'
}
创建Adapter
public class QuickAdapter extends BaseQuickAdapter<Status> {
public QuickAdapter(Context context) {
super(context, 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())
.setImageUrl(R.id.tweetAvatar, item.getUserAvatar())
.setVisible(R.id.tweetRT, item.isRetweet())
.linkify(R.id.tweetText);
}
}
添加item点击事件
mQuickAdapter.setOnRecyclerViewItemClickListener(new BaseQuickAdapter.OnRecyclerViewItemClickListener() {
@Override
public void onItemClick(View view, int position) {
}
});
添加动画
// 一行代码搞定（默认为渐显效果） quickAdapter.openLoadAnimation();
另外也可以制定其他的动画效果
// 默认提供5种方法（渐显、缩放、从下到上，从左到右、从右到左） // ALPHAIN, SCALEIN, SLIDEIN_BOTTOM, SLIDEIN_LEFT, SLIDEIN_RIGHT quickAdapter.openLoadAnimation(BaseQuickAdapter.ALPHAIN);
另外，如果内置的动画效果不满意，也可易自定义
// 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)
};
}
});
添加多种类型item
public class MultipleItemQuickAdapter extends BaseMultiItemQuickAdapter<MultipleItem> {
public MultipleItemQuickAdapter(Context context, List data) {
super(context, data);
addItmeType(MultipleItem.TEXT, R.layout.text_view);
addItmeType(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;
}
}
}
添加头部及底部
mQuickAdapter.addHeaderView(getView());
mQuickAdapter.addFooterView(getView());
加载更多
mQuickAdapter.setOnLoadMoreListener(PAGE_SIZE, new BaseQuickAdapter.RequestLoadMoreListener() {
@Override
public void onLoadMoreRequested() {
if (mCurrentCounter >= TOTAL_COUNTER) {
mRecyclerView.post(new Runnable() {
@Override
public void run() {
mQuickAdapter.isNextLoad(false);
}
});
} else {
// reqData
mCurrentCounter = mQuickAdapter.getItemCount();
mQuickAdapter.isNextLoad(true);
}
}
});
使用分组
public class SectionAdapter extends BaseSectionQuickAdapter<MySection> {
public SectionAdapter(Context context, int layoutResId, int sectionHeadResId, List data) {
super(context, 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);
if(!item.isMroe)helper.setVisible(R.id.more,false);
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();
}
});
}
使用setEmptyView
mQuickAdapter.setEmptyView(getView());
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();
}
});
