无法在回收者视图中从一项活动转到另一项活动

大家好，我正在尝试使用回收器视图的适配器类中的意图从一个活动移动到另一个活动，但这样做时出现 son=me 错误，以下是错误： 1.PakistaniActivity 不是一个封闭类。 2.无法解析StatrActivity()方法；

这是我的代码：

巴基斯坦Activity.Java

   package com.recycler.hp.navigationbar;

    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.support.v7.widget.LinearLayoutManager;
    import android.support.v7.widget.RecyclerView;

     public class PakistaniActivity extends AppCompatActivity {

    @Override
      protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_pakistani);
    RecyclerView rl=findViewById(R.id.list);
    rl.setLayoutManager(new LinearLayoutManager(this));
    String[] languges={"Badnamiyan", "song2","song3","song4","Song5","song6","song7","song8","song9"};
    rl.setAdapter(new Adaptor(languges));
    }
     }

适配器.java

     package com.recycler.hp.navigationbar;

    import android.content.Intent;
     import android.media.AudioManager;
    import android.media.MediaPlayer;
    import android.support.v7.widget.RecyclerView;
    import android.view.LayoutInflater;
    import android.view.View;
     import android.view.ViewGroup; 
      import android.widget.Button;
       import android.widget.ImageButton;
     import android.widget.ImageView;
     import android.widget.TextView;
     import android.widget.Toast;

      import java.io.IOException;
      import java.net.URL;



       public class Adaptor extends RecyclerView.Adapter<Adaptor.viewholder> {
private String[] data;

public Adaptor(String[] data) {
    this.data = data;
}


@Override
public viewholder onCreateViewHolder(ViewGroup parent, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View view = inflater.inflate(R.layout.list_item1, parent, false);
    return new viewholder(view);
}

@Override
public void onBindViewHolder(viewholder holder, final int position) {
    String title = data[position];
    holder.t.setText(title);
    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
             long x;
             x=getItemId(position);
            if(x==0)
            {
                 Intent intent=new Intent(PakistaniActivity.this,Revival_Activity.class);
                 startActivity(intent);
            }
        }
    });

}

@Override
public int getItemCount() {
    return data.length;
}

public class viewholder extends RecyclerView.ViewHolder {
    ImageView i;
    TextView t;

    public viewholder(View itemView) {
        super(itemView);
        i = itemView.findViewById(R.id.img1);
        t = itemView.findViewById(R.id.main1);
    }
}

   }

尝试不要启动适配器内的活动。您可以使用此适配器：

public abstract class ClickableAdapter<VH extends RecyclerView.ViewHolder> extends RecyclerView.Adapter<VH> {

    private ClickItemListener clickItemListener;

    public void setClickItemListener(ClickItemListener clickItemListener) {
        this.clickItemListener = clickItemListener;
    }


    @Override
    public void onBindViewHolder(@NonNull final VH holder, int position) {
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (clickItemListener != null)
                    clickItemListener.onClickItem(holder.itemView, holder.getAdapterPosition());
                else
                    throw new IllegalStateException("Click listener not set");
            }
        });
    }

    public interface ClickItemListener {
        void onClickItem(View v, int position);
    }
}

然后让你的适配器扩展我的：

public class Adaptor extends ClickableAdapter<Adaptor.viewholder> {
private String[] data;

public Adaptor(String[] data) {
    this.data = data;
}


@Override
public viewholder onCreateViewHolder(ViewGroup parent, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View view = inflater.inflate(R.layout.list_item1, parent, false);
    return new viewholder(view);
}

@Override
public void onBindViewHolder(viewholder holder, final int position) {
    super.onBindViewHolder(holder,position);
    String title = data[position];
    holder.t.setText(title);

}

@Override
public int getItemCount() {
    return data.length;
}

public class viewholder extends RecyclerView.ViewHolder {
    ImageView i;
    TextView t;

    public viewholder(View itemView) {
        super(itemView);
        i = itemView.findViewById(R.id.img1);
        t = itemView.findViewById(R.id.main1);
    }
}

   }

最后，在您的活动中，您可以设置适配器的行为：

Adaptor adapter = new Adaptor(languges)
rl.setAdapter(adapter);

adapter.setClickItemListener(new ClickableAdapter.ClickItemListener() {
            @Override
            public void onClickItem(View v, int position) {
                if(position==0)
            {
                 Intent intent=new Intent(PakistaniActivity.this,Revival_Activity.class);
                 startActivity(intent);
            }

            }
        });
