我有一个列表视图（不是 recyclerView），其中每一行都有一个按钮、几个文本视图和一个 EditText。 单击特定按钮（“editTremp”）后，我希望 EditText 进入编辑模式。
我的问题是：每次按下按钮（无论在哪一行），它仅在列表视图的最后一行触发，而不是在按钮所在的特定行触发。我看过很多答案，但没有人适合我。 我该如何解决它？
这是listview_row的布局

更新： ViewHolder 的解决方案效果很好！ 这是带有 ViewHolder 的新适配器代码。如果您有任何改进建议，那就太好了！

您可以使用Recycleview并设置自定义适配器：
适配器：
public class TestAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
Context ctx;
public ArrayList<String> mListItem;
ArrayList<String> item;
public TestAdapter(Context ctx, ArrayList<String> mListItem) {
this.ctx = ctx;
this.mListItem = mListItem;
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
final View view = LayoutInflater.from(ctx).inflate(R.layout.row_watch_company, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
ViewHolder mViewHolder = (ViewHolder)holder;
mViewHolder.button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//do your task
}
});
}
@Override
public int getItemCount() {
return 10;
}
class ViewHolder extends RecyclerView.ViewHolder {
Button button;
public ViewHolder(View rowView) {
super(rowView);
button = (Button)rowView.findViewById(R.id.button);
}
}
}
片段/活动中的Recyclerview：
rvAdvisor = (RecyclerView) view.findViewById(R.id.rvAdvisor);
rvAdvisor.setLayoutManager(new LinearLayoutManager(getActivity()));
rvAdvisor.setAdapter(new TestAdapter (getActivity());//pass data here
