我很想尝试在DialogFragment的适配器中实现ClickListener。
我在代码行中收到错误:
holder.bind(tzmodel.get(position),监听器);
错误说(无法应用ViewHolder中的bind())。似乎与ViewHolder代码不匹配。
有人可以帮忙吗?
timeZoneAdapter的代码:
public class timeZoneAdapter extends RecyclerView.Adapter<timeZoneAdapter.ViewHolder> {
public interface OnItemClickListener {
void onItemClick(TimezoneModel item);
}
private Context c;
private List<TimezoneModel> tzmodel;
private final OnItemClickListener listener;
public timeZoneAdapter(Context c, List<TimezoneModel> tzModel, OnItemClickListener listener) {
this.c = c;
this.tzmodel = tzModel;
this.listener = listener;
}
//INITIALIE TZ
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.timezonemodel, parent, false);
return new ViewHolder(v);
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
holder.bind(tzmodel.get(position), listener); <-- error
}
@Override
public int getItemCount() {
return tzmodel.size();
}
class ViewHolder extends RecyclerView.ViewHolder {
TextView timeTxt, currenttimeTxt, regionTxt;
public ViewHolder(View itemView) {
super(itemView);
timeTxt= (TextView) itemView.findViewById(R.id.timeTxt);
currenttimeTxt= (TextView) itemView.findViewById(R.id.currentTimeTxt);
regionTxt= (TextView) itemView.findViewById(R.id.regionTxt);
}
public void bind(ViewHolder viewHolder, int i, final OnItemClickListener listener) {
viewHolder.timeTxt.setText(tzmodel.get(i).getTime());
viewHolder.currenttimeTxt.setText(tzmodel.get(i).getCurrentTime());
viewHolder.regionTxt.setText(tzmodel.get(i).getRegion());
itemView.setOnClickListener(new View.OnClickListener() {
@Override public void onClick(View v) {
listener.onItemClick((TimezoneModel) tzmodel);
}
});
}
}
}
答案 0 :(得分:0)
问题是您放入定义的bind方法中的参数。
您可以通过以下方式在ViewHolder类中定义公共方法绑定:
public void bind(ViewHolder viewHolder, int i, final OnItemClickListener listener){
//...
}
您可以解决编译错误,将调用更改为:
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
holder.bind(holder,position, listener);
}
我还与您分享一些更正,因为如果您在ViewHolder类中创建一个公共方法,则无需配方viewHolder实例,因为可以使用此运算符进行访问:
public class TimeZoneAdapter extends RecyclerView.Adapter<TimeZoneAdapter.ViewHolder> {
public interface OnItemClickListener {
void onItemClick(TimezoneModel item);
}
private Context c;
private List<TimezoneModel> tzmodel;
private final OnItemClickListener listener;
public TimeZoneAdapter(Context c, List<TimezoneModel> tzModel, OnItemClickListener listener) {
this.c = c;
this.tzmodel = tzModel;
this.listener = listener;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false);
return new ViewHolder(v);
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
holder.bind(tzmodel.get(position), listener);
}
@Override
public int getItemCount() {
return tzmodel.size();
}
class ViewHolder extends RecyclerView.ViewHolder {
TextView timeTxt, currenttimeTxt, regionTxt;
public ViewHolder(View itemView) {
super(itemView);
timeTxt= itemView.findViewById(R.id.timeTxt);
currenttimeTxt= itemView.findViewById(R.id.currentTimeTxt);
regionTxt= itemView.findViewById(R.id.regionTxt);
}
public void bind(TimezoneModel item , final OnItemClickListener listener) {
this.timeTxt.setText(item.getTime());
this.currenttimeTxt.setText(item.getCurrentTime());
this.regionTxt.setText(item.getRegion());
itemView.setOnClickListener(new View.OnClickListener() {
@Override public void onClick(View v) {
listener.onItemClick((TimezoneModel) tzmodel);
}
});
}
}
}
