我已经实现了RecyclerView.现在我想在单击RecyclerView的项目时显示AlertDialog.我尝试了很多方法,但没有一个工作.这是我的适配器类,

public class SearchResultAdapter extends RecyclerView.Adapter<SearchResultAdapter.MyViewHolder> {
private List<Searchresult> resultList;

public class MyViewHolder extends RecyclerView.ViewHolder {
    public TextView item1, item2, item3;

    public MyViewHolder(View view) {
        super(view);
        item1 = (TextView) view.findViewById(R.id.item1);
        item2 = (TextView) view.findViewById(R.id.item2);
        item3 = (TextView) view.findViewById(R.id.item3);
    }
}

public SearchResultAdapter(List<Searchresult> resultList) {
    this.resultList = resultList;
}

@Override
public MyViewHolder onCreateViewHolder(final ViewGroup parent, int viewType) {
    final View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.search_result_row, parent, false);
    return new MyViewHolder(itemView);
}

@Override
public void onBindViewHolder(final MyViewHolder holder, int position) {
    Searchresult result …

我想像这样给按钮上色。有什么办法可以通过使用 css 来做到这一点吗？

按钮应该是这样的
