+# 代码非常简单，基于dataBinding
+
+## 详细示例见本项目app下的MainActivity
+### 说明：adapter的功能、方向及逻辑已经明确，后续将稳定发版，不会有较大改动
+
+一个listAdapter只需要如下一行（没错，总共就一行）
+```
+   BaseAdapterRvList<?, String> adapter = BaseAdapterRvList.createAdapter(R.layout.adapter_main_list);
+```
+当然，你的xml是基于dataBinding的
+```
+<?xml version="1.0" encoding="utf-8"?>
+<layout xmlns:android="http://schemas.android.com/apk/res/android"
+    xmlns:tools="http://schemas.android.com/tools">
+
+    <data>
+
+        <!--        adapter默认会设置并刷新“bean”这个属性-->
+        <variable
+            name="bean"
+            type="String" />
+    </data>
+
+    <TextView
+        android:layout_width="match_parent"
+        android:layout_height="wrap_content"
+        android:background="#fff"
+        android:padding="10dp"
+        android:text="@{bean}"
+        android:textColor="#333"
+        android:textSize="20sp"
+        tools:text="这是文本" />
+</layout>
+```
+自带点击事件
+```
+        adapter.setOnItemClickListener(new OnItemClickListener() {
+            @Override
+            public void onItemClick(@NonNull View view, int listPosition) {
+            }
+
+            @Override
+            public boolean onItemLongClick(@NonNull View view, int listPosition) {
+                return true;
+            }
+
+            @Override
+            protected void onFooterClick(@NonNull View view) {
+                super.onFooterClick(view);
+            }
+            //...header、footer long click
+        });
+```
+自带header、footer
+```
+adapter.setHeaderView(view);
+adapter.setFooterView(view);
+```
+当然你也可以自定义一些简单逻辑
+```
+BaseAdapterRvList<AdapterMainListBinding, String> adapter = BaseAdapterRvList.createAdapter(list, R.layout.adapter_main_list,
+        (holder, listPosition, s) -> {
+            if (s.contains("10")) {
+                holder.itemView.setBackgroundColor(0xff999999);
+            }
+        });//回调还有onViewHolderCreated方法
+```
+也可以完全自定义（没有看错，不需要layoutId）
+```
+    public static class ListAdapter extends BaseAdapterRvList<AdapterMainListBinding, String> {
+
+        @Override
+        public void onBindListViewHolder(@NonNull BaseViewHolder<AdapterMainListBinding> holder, int listPosition, String s) {
+            if (s.contains("100")) {
+                getList().set(listPosition, "改掉了100");//后面会调用刷新dataBinding
+                holder.getBinding().viewBackground.setBackgroundColor(0xff00ff00);
+            } else if (s.contains("10")) {
+                holder.getBinding().viewBackground.setBackgroundColor(0xff999999);
+            } else {
+                holder.getBinding().viewBackground.setBackgroundColor(0xffffffff);
+            }
+        }
+
+        @NonNull
+        @Override
+        public BaseViewHolder<AdapterMainListBinding> onCreateListViewHolder(@NonNull ViewGroup parent) {
+            BaseViewHolder<AdapterMainListBinding> holder = super.onCreateListViewHolder(parent);
+            holder.itemView.setBackgroundColor(0xffeeeeee);
+            return holder;
+        }
+    }
+```
+ViewPager的Fragment更简单
+```
+mVp.setAdapter(new BaseFragmentPagerAdapter(getSupportFragmentManager(), mFrags));
+//或
+mVp.setAdapter(new BaseFragmentPagerAdapter(getSupportFragmentManager(), frag1,frag2...));
+//动态修改frag
+mAdapter = new BaseFragmentStatePagerAdapter(getSupportFragmentManager(), mFrags);
+mVp.setAdapter(mAdapter);
+...
+mAdapter.getFragments().add(xxx);//由于内部有新的list，所以并不能用自己的mFrags
+mAdapter.getFragments().remove(yyy);
+mAdapter.notifyDataSetChanged();
+//解决动态修改刷新白屏的问题
+BaseFragmentNotifyAdapter adapter = new BaseFragmentNotifyAdapter(getSupportFragmentManager(), mFrags);
+mVp.setAdapter(adapter);
+...
+adapter.notifyAllItem(1);//保留展示的frag这样就不会白屏了，想要刷新这个frag当然需要自己frag内部刷新了，详见app下的示例
+```
+还有适用于各种复杂样式的adapter容器（如：聊天列表，首页、今日头条的列表等）：
+```
+本项目已默认导入，直接使用即可：https://github.com/weimingjue/BaseContainerAdapter
+```
+
+## 导入方式
+你的build.gradle要有jitpack.io，大致如下
+```
+allprojects {
+    repositories {
+        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
+        maven { url 'https://jitpack.io' }
+        google()
+        jcenter()
+    }
+}
+```
+
+### AndroidX dataBinding：
+`（api或）implementation 'com.github.weimingjue:BaseAdapter:3.61'`
+
+不需要layoutId的混淆要求：
+```
+#框架特殊要求
+# 根据泛型获取res资源需要
+-keep class * extends androidx.databinding.ViewDataBinding
+```
