我有TextView和Button在RecyclerView我把文本上Button的數量當我點擊按鈕我想1這個數字的增加，當我嘗試遞歸setonclicklistener應用程序不工作 我有兩個活動，他們每個人的調用相同的適配器 適配器的代碼如何在按鈕點擊多次在同一活動
public class AzkaarAdapter extends RecyclerView.Adapter<AzkaarAdapter.AzkaarViewHolder> {
ArrayList<AzkarForm> azkarForms=new ArrayList<AzkarForm>();
Context ctx;
private static ItemClickCallback itemClickCallback;
public interface ItemClickCallback {
void onItemClick(int p);
void onSecondaryIconClick(int p);
}
public void setItemClickCallback(final ItemClickCallback itemClickCallback) {
this.itemClickCallback = itemClickCallback;
}
public AzkaarAdapter (ArrayList<AzkarForm> azkarForms,Context ctx){
this.azkarForms=azkarForms;
this.ctx=ctx;
}
@Override
public AzkaarViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
AzkaarViewHolder azkaarViewHolder;
if(ctx instanceof MainActivity){
View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview_layout,parent,false);
azkaarViewHolder=new AzkaarViewHolder(view,ctx,azkarForms);
}
else {
View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview_details,parent,false);
azkaarViewHolder=new AzkaarViewHolder(view,ctx,azkarForms);
}
return azkaarViewHolder;
}
@Override
public void onBindViewHolder(AzkaarViewHolder holder, int position) {
AzkarForm azkarForm=azkarForms.get(position);
if(ctx instanceof MainActivity) {
holder.sample.setText(azkarForm.getComplete_morning());
holder.number.setText(String.valueOf(azkarForm.getNumber()));
}else {
holder.sample.setText(azkarForm.getComplete_morning());
holder.tally_count.setText(getTextNumber(azkarForm.getNumber()));
}
}
public String getTextNumber(int number){
String numberText="";
switch (number){
case 1:
numberText="مرة واحدة";
break;
case 3:

break;
case 10:
numberText="عشر مرات";
break;
case 100:
numberText="مائة مرة";
break;
}
return numberText;
}
@Override
public int getItemCount() {
return azkarForms.size();
}
public static class AzkaarViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
TextView sample, number;
View container;
Context ctx;
ArrayList<AzkarForm> azkarForms = new ArrayList<AzkarForm>();
Button tally_count,press,next;
public AzkaarViewHolder(View itemView, Context ctx, ArrayList<AzkarForm> azkarForms) {
super(itemView);
this.ctx = ctx;
//itemView.setOnClickListener(this);
this.azkarForms = azkarForms;
if(this.ctx instanceof MainActivity) {
sample = (TextView) itemView.findViewById(R.id.sample);
number = (TextView) itemView.findViewById(R.id.number);

container.setOnClickListener(this);
}else {

}
//container.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.container){
itemClickCallback.onItemClick(getAdapterPosition());
} else {
itemClickCallback.onSecondaryIconClick(getAdapterPosition());
}
/*if(Build.VERSION.SDK_INT >=Build.VERSION_CODES.LOLLIPOP){

}
}
}
第一個活動
recyclerView =(RecyclerView) findViewById(R.id.recyclerviewcard);
layoutManager=new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setHasFixedSize(true);
adapter=new AzkaarAdapter(AzkaarData.getArrayListData(),this);
recyclerView.setAdapter(adapter);
adapter.setItemClickCallback(this);
toolbar=(Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
@Override
public void onItemClick(int p) {
//int position=getAdapterPosition();
AzkarForm azkarForm= list.get(p);
Intent intent=new Intent(this,DetailsActivity.class);
intent.putExtra("numbers",azkarForm.getNumber());
intent.putExtra("sample",azkarForm.getSample());
intent.putExtra("complete",azkarForm.getComplete_morning());
intent.putExtra("position",p);
this.startActivity(intent);
}
@Override
public void onSecondaryIconClick(int p) {
}
次活動
recyclerView =(RecyclerView) findViewById(R.id.recyclerviewcard);
layoutManager=new LinearLayoutManager(DetailsActivity.this,LinearLayoutManager.HORIZONTAL,false);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setHasFixedSize(true);
recyclerView.scrollToPosition(pos);
adapter=new AzkaarAdapter(AzkaarData.getArrayListData(),this);
recyclerView.setAdapter(adapter);
SnapHelper snapHelper = new LinearSnapHelper();
snapHelper.attachToRecyclerView(recyclerView);
toolbar=(Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
@Override
public void onItemClick(int p) {
}
@Override
public void onSecondaryIconClick(int p) {
AzkarForm azkarForm= list.get(p);
press=(Button) findViewById(R.id.press);
int currentNum=Integer.parseInt(press.getText().toString());
int num=azkarForm.getNumber();
if(currentNum<num){
currentNum++;
onSecondaryIconClick(p);
}
press.setText(String.valueOf(currentNum));
}
它工作正常，但當我回到recyclerview並點擊它時，它不反應，當我在第二個活動中刪除一組適配器時，它工作 –
做你得到一個錯誤？ –
沒有任何錯誤 –
