【解决方案1】：

检查下面的代码而不是这个传递上下文。

public class RecyclerAdapter extends RecyclerView.Adapter { 
String [] name={"Androidwarriors","Stackoverflow","Developer Android","AndroidHive","Slidenerd","TheNewBoston","Truiton","HmkCode","JavaTpoint","Javapeper"};
Context context; 
LayoutInflater inflater; 
public RecyclerAdapter(Context context) 
{ 
  this.context=context; 
  inflater=LayoutInflater.from(context); 
}

@Override public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
{

   View v=inflater.inflate(R.layout.item_list, parent, false);

   RecyclerViewHolder viewHolder=new RecyclerViewHolder(v);
   return viewHolder;
}

@Override
public void onBindViewHolder(RecyclerViewHolder holder, int position) {

holder.tv1.setText(name[position]);
holder.imageView.setOnClickListener(clickListener);
holder.imageView.setTag(holder);
}

View.OnClickListener clickListener=new View.OnClickListener() {
 @Override
  public void onClick(View v) {
    RecyclerViewHolder vholder = (RecyclerViewHolder) v.getTag();
    int position = vholder.getPosition();
    final Intent intent = new Intent(context, priya.class);
    context.startActivity(intent);
   }
  };
}

【解决方案2】：

改变这一行

final Intent intent = new Intent(this, priya.class);

到

final Intent intent = new Intent(CurrentActivityName.this, priya.class);

【解决方案3】：

您可以像下面这样从 RecyclerAdapter 调用活动：

final Intent intent = new Intent(context, priya.class);
context.startActivity(intent);

希望对你有帮助

【讨论】：

最终意图意图 = new Intent(context, priya.class); context.startActivity(intent);
但它是静态的

【解决方案4】：

开启新活动
在你的点击监听器中试试这个

Intent mIntent = new Intent(context, NextActivity.class);
context.startActivity(mIntent);

您可以从 First Activity 或适配器本身 v.getContext() 中获取上下文。
