Adapter封装
1.先创建一个类 名为BaseRecyclerViewAdapter
直接上封装代码
package com.orange.clientin.base.adapter;
import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.util.SparseArray;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import com.bumptech.glide.Glide;
import com.bumptech.glide.request.RequestOptions;
import com.orange.clientin.R;
import com.orange.clientin.utils.GlideUtil;
import com.rd.veuisdk.manager.Config;
import java.util.List;
public abstract class BaseRecyclerViewAdapter extends RecyclerView.Adapter {
protected List tList;
protected Context mContext;
protected LayoutInflater mLayoutInflater;
protected int layId;
private OnItemClickListener mOnItemClickListener;
protected BaseRecyclerViewAdapter.ViewHolder holder;
public BaseRecyclerViewAdapter(List tList, Context mContext, int layId) {
this.tList = tList;
this.mContext = mContext;
this.layId=layId;
mLayoutInflater=LayoutInflater.from(mContext);
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = mLayoutInflater.inflate(layId, parent, false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(final BaseRecyclerViewAdapter.ViewHolder holder, final int position) {
this.holder=holder;
convert(holder,tList.get(position),position);
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(mOnItemClickListener!=null){
mOnItemClickListener.onItemClick(position,holder,view);
}
}
});
}
@Override
public int getItemCount() {
return tList.size();
}
public abstract void convert(ViewHolder holder,T itemData,int position);
public class ViewHolder extends RecyclerView.ViewHolder {
private SparseArray mViewArray;
public ViewHolder(View itemView) {
super(itemView);
mViewArray=new SparseArray<>();
}
/**
* 通过id得到view
* @param viewId
* @param
* @return
*/
public V getViewAtId(int viewId){
View view = mViewArray.get(viewId);
if(view==null){
view=itemView.findViewById(viewId);
mViewArray.put(viewId,view);
}
return (V)view;
}
/**
* 设置Tag
* @param viewId
* @param
* @return
*/
public ViewHolder setTag(int viewId,Object object){
ImageView imageView= getViewAtId(viewId);
imageView.setTag(object);
return this;
}
/**
* 设置文字
* @param viewId
* @param text
* @return
*/
public ViewHolder setText(int viewId,CharSequence text){
TextView textView= getViewAtId(viewId);
textView.setText(text);
return this;
}
/**
* 得到文字
* @param viewId
* @return
*/
public String getText(int viewId){
TextView textView= getViewAtId(viewId);
return textView.getText().toString();
}
/**
* 设置文字
* @param viewId
* @param color
* @return
*/
public ViewHolder setTextColor(int viewId,int color){
TextView textView= getViewAtId(viewId);
textView.setTextColor(color);
return this;
}
/**
* 加载错误显示默认图
* @param context
* @param url
* @param imageView
*/
private RequestOptions default_options = RequestOptions.errorOf(R.drawable.jishuang_placeholder).placeholder(R.drawable.jishuang_placeholder);
public ViewHolder loadUrlDefault(Context context,String url,int viewId){
ImageView imageView= getViewAtId(viewId);
imageView.setTag(null);
if(url!=null && url.startsWith("GZB")){
StringBuilder sb = new StringBuilder(Config.OSSHEADER);
sb.append("/");
sb.append(url);
url = sb.toString();
}
Glide.with(context).load(url).apply(default_options).into(imageView);
return this;
}
/**
* 加载图片
* @param viewId
* @return
*/
public ViewHolder setImageFromUrl(int viewId,String imgUrl){
ImageView imageView= getViewAtId(viewId);
GlideUtil.loadUrlDefault(imageView.getContext(),imgUrl,imageView);
return this;
}
/**
* 通过资源来设置图片资源
* @param viewId
* @param resId
* @return
*/
public ViewHolder setImageFromRes(int viewId,int resId){
ImageView imageView = getViewAtId(viewId);
imageView.setImageResource(resId);
return this;
}
/**
* 设置背景颜色
* @param viewId
* @param color
* @return
*/
public ViewHolder setBackgroundColor(int viewId,int color){
RelativeLayout relativeLayout = getViewAtId(viewId);
relativeLayout.setBackgroundColor(color);
return this;
}
/**
* 设置背景样式
* @param viewId
* @param resid
* @return
*/
public ViewHolder setBackground(int viewId, int resid){
RelativeLayout relativeLayout = getViewAtId(viewId);
if(resid==0){
relativeLayout.setBackground(null);
}else relativeLayout.setBackgroundResource(resid);
return this;
}
/**
* 设置背景样式
* @param viewId
* @param resid
* @return
*/
public ViewHolder setBackgroundText(int viewId, int resid){
TextView textView = getViewAtId(viewId);
textView.setBackgroundResource(resid);
return this;
}
/**
* 设置点击事件
* @param viewId
*@return
*/
public ViewHolder SetOnItemClickListener(int viewId,View.OnClickListener onClickListener){
View view = getViewAtId(viewId);
view.setOnClickListener(onClickListener);
return this;
}
/**
* 设置控件透明度
* @param viewId
* @param visibility
* @return
*/
public ViewHolder setViewVisibility(int viewId,int visibility){
View view = getViewAtId(viewId);
view.setVisibility(visibility);
return this;
}
}
/**
* 点击事件接口
*/
public interface OnItemClickListener{
void onItemClick(int position,BaseRecyclerViewAdapter.ViewHolder viewHolder,View view);
}
public void setOnItemClickListener(OnItemClickListener onItemClickListener){
this.mOnItemClickListener=onItemClickListener;
}
}
2.再加上Glide封装
public class GlideUtil {
/**
* 默认的加载方式
* @param context
* @param url
* @param imageView
*/
public static void loadUrl(Context context, String url, ImageView imageView){
imageView.setTag(null);
Glide.with(context).load(url).into(imageView);
}
public static void loadOssUrl(Context context,String url,ImageView imageView){
imageView.setTag(null);
if(url!=null && url.startsWith("GZB")){
StringBuilder sb = new StringBuilder(Config.OSSHEADER);
sb.append("/");
sb.append(url);
url = sb.toString();
}
Glide.with(context).load(url).into(imageView);
}
private static RequestOptions options = RequestOptions.errorOf(R.drawable.sznc_tx_nan);
public static void loadOssUrlHeader(Context context,String url,ImageView imageView){
imageView.setTag(null);
if(url!=null && url.startsWith("GZB")){
StringBuilder sb = new StringBuilder(Config.OSSHEADER);
sb.append("/");
sb.append(url);
url = sb.toString();
}
Glide.with(context).load(url).apply(options).into(imageView);
}
/**
* 加载错误显示默认图
* @param context
* @param url
* @param imageView
*/
private static RequestOptions default_options = RequestOptions.errorOf(R.drawable.jishuang_placeholder).placeholder(R.drawable.jishuang_placeholder);
public static void loadUrlDefault(Context context,String url,ImageView imageView){
imageView.setTag(null);
if(url!=null && url.startsWith("GZB")){
StringBuilder sb = new StringBuilder(Config.OSSHEADER);
sb.append("/");
sb.append(url);
url = sb.toString();
}else if(url.startsWith("videos")){
StringBuilder sb = new StringBuilder(Config.OSSOUYEHEADER);
sb.append("/");
sb.append(url);
url = sb.toString();
}
Glide.with(context).load(url).apply(default_options).into(imageView);
}
public static void loadUrlDefaultOuYe(Context context,String url,ImageView imageView){
imageView.setTag(null);
if(url!=null && url.startsWith("GZB")){
StringBuilder sb = new StringBuilder(Config.OSSOUYEHEADER);
sb.append("/");
sb.append(url);
url = sb.toString();
}
Glide.with(context).load(url).apply(default_options).into(imageView);
}
/**
* 加载错误显示默认图 头像
* @param context
* @param url
* @param imageView
*/
private static RequestOptions default_head = RequestOptions.errorOf(R.drawable.sznc_tx_nan).placeholder(R.drawable.sznc_tx_nan);
public static void loadUrlHead(Context context,String url,ImageView imageView){
imageView.setTag(null);
if(url!=null && url.startsWith("GZB")){
StringBuilder sb = new StringBuilder(Config.OSSHEADER);
sb.append("/");
sb.append(url);
url = sb.toString();
}
Glide.with(context).load(url).apply(default_options).into(imageView);
}
public static void loadUrl(Context context, String url, final Simple simpleTarget){
Glide.with(context).load(url).into(new SimpleTarget() {
@Override
public void onResourceReady(@NonNull Drawable resource, @Nullable Transition transition) {
simpleTarget.Drawable(resource);
simpleTarget.Transition(transition);
}
});
}
public interface Simple{
void Drawable(Drawable resource);
void Transition(Transition resource);
}
} 3.如何使用
// 适配器
public class RecyclerAdapter extends BaseRecyclerViewAdapter {
public RecyclerAdapter(List lists, Context mContext, int layId, RecyclerView recyclerView) {
super(lists, mContext, layId);
recyclerView.setLayoutManager(new LinearLayoutManager(mContext));
}
@Override
public void convert(ViewHolder holder, String itemData, int position) {
holder.setText(R.id.text,"");
}
} 4.设置适配器
//主函数用法 str就是你的数据list R.layout.item_recycler这是你的item布局 recler这是你的recyclevice
RecyclerAdapter recyclerAdapter = new RecyclerAdapter(Str, this, R.layout.item_recycler, recler);
recler.setAdapter(recyclerAdapter);
recyclerAdapter.setOnItemClickListener(new BaseRecyclerViewAdapter.OnItemClickListener() {
@Override
public void onItemClick(int position, BaseRecyclerViewAdapter.ViewHolder viewHolder) {
// viewHolder.setText(R.id.text,"9");
}
});
