我使用的项目之一 ListView向用户显示项目列表，它就像一个魅力。现在作为尝试，我用 RecyclerView 替换了 Listview并成功向用户显示项目。
好吧，问题是每当我使用自定义的 Listview 项目时，它都会与 Listview 一起工作。但是当我尝试使用 RecyclerView 加载相同内容时，它没有对齐/适合屏幕。
这是我的预期结果..我通过使用 ListView 实现了这一点..这是我期待的结果
但是当我使用 RecyclerView 时，它显示如下。
但是我使用相同的 listview_item xml 加载两个 View ..
这是我的 listview_item.xml

适配器类:
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
private static ArrayList<SearchParms> itemData;
private static Context abc;
private int durationOfPatientRecord;
View itemLayoutView;
public MyAdapter( ArrayList<SearchParms> items, Context context) {

this.abc=context;
}
// Create new views (invoked by the layout manager)
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
itemLayoutView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_row_serch, null);
// create ViewHolder
ViewHolder viewHolder = new ViewHolder(itemLayoutView);
return viewHolder;
}
// Replace the contents of a view (invoked by the layout manager)
public void onBindViewHolder(ViewHolder viewHolder, final int position) {
// - get data from your itemsData at this position
// - replace the contents of the view with that itemsData
SearchParms item = itemData.get( position );
viewHolder.textView1.setText( item.getPartcipantId());
viewHolder.textView2.setText( item.getParticipantName());
viewHolder.textView3.setText( "" + item.getAge());
viewHolder.textView4.setText( item.getCreateDate());
viewHolder.imgView1.setImageResource( R.drawable.finalise );
viewHolder.imgView2.setImageResource( R.drawable.yesgreen );
viewHolder.imgView3.setImageResource( R.drawable.yesgreen );
itemLayoutView.setBackgroundColor( Color.parseColor( "#15ffffff" ) );
}
}
// inner class to hold a reference to each item of RecyclerView
public static class ViewHolder extends RecyclerView.ViewHolder implements OnClickListener {
public TextView textView1, textView2,textView3, textView4, textView5;
public ImageView imgView1, imgView2, imgView3, imgView4;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
textView1 = (TextView) itemLayoutView.findViewById(R.id.textView1);
textView2 = (TextView) itemLayoutView.findViewById(R.id.textView2);
textView3 = (TextView) itemLayoutView.findViewById(R.id.textView3);

imgView4 = (ImageView) itemLayoutView.findViewById(R.id.imageView2);
itemLayoutView.setOnClickListener(this);
}
@Override
public void onClick(View v) {
int i=getAdapterPosition();
SearchParms item = itemData.get( i );
Toast.makeText(abc, "You Selected:: " +item.getParticipantName(), 3000).show();
}
}
// Return the size of your itemsData (invoked by the layout manager)
@Override
public int getItemCount() {
return itemData.size();
}
}
哪里出了问题。使用 RecyclerView 有任何类型的限制吗？很想知道这件事。谢谢
最佳答案
而不是像这样设置你的 View :
itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(
R.layout.list_row_serch, null);
执行以下操作:
itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(
R.layout.list_row_serch, parent, false);
