Android进阶之路 - 封装完善的BaseAdapter之BaseQuickAdapter

项目中现在已经很少用到ListView这款老控件了，大多用的RecyclerView，一般的话我们都自己有一些简单的封装，但是相对而言不是很完善，扩展性并不是很强，所有找到了BaseRecyclerViewAdapterHelper，它是一款BaseAdapter的集合体，在Github的Start较多，也较为好用，因为封装比较全面，下面有一些使用方法。

Effect :



提前引入

build.gradle (项目级):

allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}

build.gradle (app级):

compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.30'

现在即可调用BaseRecyclerViewAdapterHelper

TextAdapter （继承BaseQuickAdapter，只实现俩个方法即可，但是需要你绑定对应的model）：

package com.bakheet.effect.adaptertext;

import android.support.annotation.LayoutRes;
import android.support.annotation.Nullable;
import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;

import java.util.List;

/**

*/

public class TextAdapter extends BaseQuickAdapter<TextBean, BaseViewHolder> {

public TextAdapter(@LayoutRes int layoutResId, @Nullable List data) {
super(layoutResId, data);
}

@Override
protected void convert(BaseViewHolder helper, TextBean item) {
helper.setText(R.id.tv_item,item.getName());

helper.addOnClickListener(R.id.tv_btn).addOnLongClickListener(R.id.tv_btn);
}
}

MainActivity （使用常规的RecyclerView控件即可，因为我们主要作用与Adapter方面）:

package com.bakheet.effect.adaptertext;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.widget.Toast;

import com.chad.library.adapter.base.BaseQuickAdapter;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

private RecyclerView mRv;
private TextAdapter adapter;
private ArrayList<TextBean> lists;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

lists = new ArrayList<TextBean>();
initData();

mRv = (RecyclerView) findViewById(R.id.rv);
mRv.setLayoutManager(new LinearLayoutManager(this));
adapter = new TextAdapter(R.layout.item_layout, lists);
mRv.setAdapter(adapter);

adapter.openLoadAnimation();

//        默认提供5种方法（渐显、缩放、从下到上，从左到右、从右到左）
//        adapter.openLoadAnimation(BaseQuickAdapter.FOOTER_VIEW);

adapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {
@Override
public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(MainActivity.this, "触发子条目提示" + position, Toast.LENGTH_SHORT).show();
}
});

adapter.setOnItemLongClickListener(new BaseQuickAdapter.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(BaseQuickAdapter adapter, View view, int position) {

Toast.makeText(MainActivity.this, "子条目长按提示" + position, Toast.LENGTH_SHORT).show();
return true;
}
});

adapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
switch (view.getId()) {
case R.id.tv_btn:
Toast.makeText(MainActivity.this, "内部 - 子条目点击提示" + position, Toast.LENGTH_SHORT).show();
break;
default:
break;
}
}
});

adapter.setOnItemChildLongClickListener(new BaseQuickAdapter.OnItemChildLongClickListener() {
@Override
public boolean onItemChildLongClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(MainActivity.this, "内部 - 子条目长按提示" + position, Toast.LENGTH_SHORT).show();
return true;
}
});

}

private void initData() {
for (int i = 0; i < 55; i++) {
TextBean textBean = new TextBean();
textBean.setName("吃土一个月" + i);
lists.add(textBean);
}
}
}

MainActivity Xml :

<?xml version="1.0" e
d4f5
ncoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.bakheet.effect.adaptertext.MainActivity">

<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/rv"
/>

</LinearLayout>

TextBean :

package com.bakheet.effect.adaptertext;

/**
* Created by YongLiu on 2017/11/10.
*/

public class TextBean {
public String name;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}
}

注意（个人使用不完善） ：

动画引入

//        默认提供5种方法（渐显、缩放、从下到上，从左到右、从右到左）
//        adapter.openLoadAnimation(BaseQuickAdapter.FOOTER_VIEW);

事件监听

//如只使用普通的Item点击和长按操作，可直接调用

adapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {
@Override
public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(MainActivity.this, "触发子条目提示" + position, Toast.LENGTH_SHORT).show();
}
});

adapter.setOnItemLongClickListener(new BaseQuickAdapter.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(BaseQuickAdapter adapter, View view, int position) {

Toast.makeText(MainActivity.this, "子条目长按提示" + position, Toast.LENGTH_SHORT).show();
return true;
}
});

如操作Item内部子视图的点击和长按操作（如下面第一种，可处理内部多个事件，需要绑定对应的Id,但是需要在Adapter内设置设个事件）

*adapter需设置

//一个点击一个长按helper.addOnClickListener(R.id.tv_btn).addOnLongClickListener(R.id.tv_btn);

使用方式

adapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
switch (view.getId()) {
case R.id.tv_btn:
Toast.makeText(MainActivity.this, "内部 - 子条目点击提示" + position, Toast.LENGTH_SHORT).show();
break;
default:
break;
}
}
});

adapter.setOnItemChildLongClickListener(new BaseQuickAdapter.OnItemChildLongClickListener() {
@Override
public boolean onItemChildLongClick(BaseQuickAdapter adapter, View view, int position) {
Toast.makeText(MainActivity.this, "内部 - 子条目长按提示" + position, Toast.LENGTH_SHORT).show();
return true;
}
});
