MainActivity.java public class MainActivity extends AppCompatActivity { ArrayList<DashModel> dashModelArrayList; RecyclerView recyclerView; DashAdapter dashAdapter; protected void onCreate (Bundle saveInstanceS
public class MainActivity extends AppCompatActivity {
ArrayList<DashModel> dashModelArrayList;
RecyclerView recyclerView;
DashAdapter dashAdapter;
protected void onCreate (Bundle saveInstanceState) {
super.onCreate(saveInstanceState);
setContentView(R.layout.layoutgirdm);

String heads[] = {"jobs","profile","message","apple","setting"};
String subs[] = {"12 news","75 complete","2 new messages","3pplie","edit","set pref"};

DashModel dashModel = new DashModel();
for(int count = 0 ; count < heads.length; count++){
dashModel.setHead(heads[count]);
dashModel.setSub(subs[count]);
dashModel.setImage(images[0]);
dashModelArrayList.add(dashModel);
}
LinearLayoutManager layoutManager = new LinarLayoutManager(this,LinearLayoutManager.HORIZONTAL,false);
recyclerView.setLayoutManager(layoutManager);
dashAdapter = new DashAdapter(dashModelArrayList);
recyclerView.setHasFixedSize(true);
recyclerView.setAdapter(dashAdapter);
}
public类MainActivity扩展了AppCompatActivity{
ArrayList dashModelArrayList；
回收视图回收视图；
DashAdapter；
创建时受保护的void（Bundle saveInstanceState）{
super.onCreate（saveInstanceState）；
setContentView（R.layout.layoutgirdm）；
recyclerView=findViewById（R.id.rv1）；
dashModelArrayList=新建ArrayList（）；
字符串头[]={“乔布斯”、“个人资料”、“消息”、“苹果”、“设置”}；
字符串subs[]={“12条新闻”、“75条完整消息”、“2条新消息”、“3条应用程序”、“编辑”、“设置优先级”}；
int images[]={R.drawable.ic_lock_24px}；
DashModel DashModel=新DashModel（）；
对于（int count=0；count从ViewHolder构造函数调用此方法
ViewHolder上受保护的无效已创建（ViewHolder ViewHolder）{
RelativeLayout.LayoutParams params=（RelativeLayout.LayoutParams）viewHolder.binding.rlContent.getLayoutParams（）；
params.width=totalWidth/getItemCount（）；
viewHolder.rlContent.setLayoutParams（params）；
}
