单击回收视图并切换到新活动

Question

我想如何将setOnClickListener函数添加到我的代码中，并将继续单击记录的信息推送到另一个活动。我不知道该怎么做。我很高兴接受帮助。谢谢。

我已附上我正在使用的两段代码：这是我的adCake.java类：

 package com.lee.app1_new;

public class adCake {

private String image;
private String name;
private String ingredients;
private String preparation;


public adCake(String image, String name, String ingredients, String preparation) {
    this.image = image;
    this.name = name;
    this.ingredients = ingredients;
    this.preparation = preparation;
}


public void setImage(String image) {
    this.image = image;
}
public String getImage() {
    return image;
}

public void setName(String name) {
    this.name = name;
}
public String getName() {
    return name;
}


public void setIngredients(String ingredients) {
    this.ingredients = ingredients;
}

public void setPreparation(String preparation) {
    this.preparation = preparation;
}




public String getIngredients() {
    return ingredients;
}

public String getPreparation() {
    return preparation;
}
public adCake(){
    super();
}




}

这是我的recycle_recipe.java类：

package com.lee.app1_new;

import android.content.Context;
import android.media.Image;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

import com.firebase.ui.database.FirebaseRecyclerAdapter;


 import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;
import com.squareup.picasso.Picasso;

public class recycle_recipe extends AppCompatActivity {

private RecyclerView mRlist;
private DatabaseReference mDatabase;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_recycle_recipe);

    mDatabase= FirebaseDatabase.getInstance().getReference().child("cake");
    mDatabase.keepSynced(true);
    mRlist=findViewById(R.id.recycle);
   // mRlist.setHasFixedSize(true);
    mRlist.setLayoutManager(new LinearLayoutManager(this));


}

@Override
protected void onStart() {
    super.onStart();


    FirebaseRecyclerAdapter<adCake,adCakeViewHolder> firebaseRecyclerAdapter=new FirebaseRecyclerAdapter<adCake,adCakeViewHolder>
            (adCake.class,R.layout.recip_card,adCakeViewHolder.class,mDatabase){
        @Override
        protected void populateViewHolder(adCakeViewHolder viewHolder,adCake model,int position)
        {
            viewHolder.setName(model.getName());
            viewHolder.setIng(model.getIngredients());
            viewHolder.setPrep(model.getPreparation());
            viewHolder.setImg(getApplicationContext(),model.getImage());

        }

    };

    mRlist.setAdapter(firebaseRecyclerAdapter);
}

   public static class adCakeViewHolder extends RecyclerView.ViewHolder{
    View mView;

    public adCakeViewHolder(@NonNull View itemView) {
        super(itemView);
        mView=itemView;
    }
    public void setName(String name)
    {
        TextView post_name=(TextView)mView.findViewById(R.id.name);
        post_name.setText(name);
    }
    public void setIng(String ing)
    {
        TextView post_ing=(TextView)mView.findViewById(R.id.ingredients);
        post_ing.setText(ing);
    }
    public void setPrep(String prep)
    {
        TextView post_prep=(TextView)mView.findViewById(R.id.preparation);
        post_prep.setText(prep);
    }
    public void setImg(Context ctx, String img)
    {
        ImageView post_img=(ImageView)mView.findViewById(R.id.image);
        Picasso.with(ctx).load(img).into(post_img);

    }
}

}

Answer 1

只需输入itemView名称而不是mView。

viewHolder.mView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent = new Intent(getBaseContext(), NextActivity.class);
        intent.putExtra("model_name", model.getName());
        startActivity(intent);                   
    }
});
