在RecyclerView列表项中包含多个TextViews可以通过自定义RecyclerView的Adapter来实现。以下是实现的步骤:
以下是一个示例代码:
// 数据模型类
public class ItemData {
private String text1;
private String text2;
public ItemData(String text1, String text2) {
this.text1 = text1;
this.text2 = text2;
}
public String getText1() {
return text1;
}
public String getText2() {
return text2;
}
}
// 适配器类
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
private List<ItemData> dataList;
public MyAdapter(List<ItemData> dataList) {
this.dataList = dataList;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
ItemData item = dataList.get(position);
holder.text1.setText(item.getText1());
holder.text2.setText(item.getText2());
}
@Override
public int getItemCount() {
return dataList.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView text1;
public TextView text2;
public ViewHolder(View itemView) {
super(itemView);
text1 = itemView.findViewById(R.id.text1);
text2 = itemView.findViewById(R.id.text2);
}
}
}
// 布局文件 item_layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
// 在Activity中使用RecyclerView
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private MyAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
List<ItemData> dataList = new ArrayList<>();
// 添加数据项到dataList
adapter = new MyAdapter(dataList);
recyclerView.setAdapter(adapter);
}
}
这样,就可以在RecyclerView的列表项中包含多个TextViews了。根据实际需求,可以自定义布局和数据模型,添加更多的TextViews或其他视图组件。
