BRVAH框架的简单使用
参考：
BRVAH官方使用指南（持续更新）
github地址
Android RecyclerView 使用完全解析 体验艺术般的控件
依赖：
project的gradle中添加：
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}module的gradle中添加：
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.30'布局：
RecyclerView列表布局：
"http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
.support.v7.widget.RecyclerView
android:id="@+id/id_recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#000000"
android:dividerHeight="10dp" />
RecyclerView的item布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal">
<TextView
android:id="@+id/id_num"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#44ff0000"
android:gravity="center"
android:text="1" />
<TextView
android:id="@+id/id_text"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#44ff4081"
android:gravity="center"
android:text="第一个" />
LinearLayout>适配器：
class HomeAdapter extends BaseQuickAdapter<String, BaseViewHolder> {
/**
* 构造方法：
*
* @param layoutResId：
* @param data：
*/
public HomeAdapter(int layoutResId, List data) {
super(layoutResId, data);
}
/**
* 设置数据
*
* @param helper ：holder
* @param item :item的数据
*/
@Override
protected void convert(BaseViewHolder helper, String item) {
helper.setText(R.id.id_num, item);//item布局的控件id、item数据
helper.setText(R.id.id_text, "第" + helper.getAdapterPosition() + "个数据");
//item布局的控件id、item数据
helper.addOnClickListener(R.id.id_num);
helper.addOnLongClickListener(R.id.id_text);
//getLayoutPosition() 获取当前item的position
if (helper.getAdapterPosition() % 2 == 0) {
helper.setTextColor(R.id.id_num, Color.RED);
} else {
helper.setTextColor(R.id.id_num, Color.YELLOW);
}
}
}设置
