如何使用 Android 中的 picasso 将图像从 recyclerview 发送到详细信息 activity

Question

在我的应用程序中，我从剩余 api json 数据中获取图像，我已在 recyclerview 中显示这些图像。现在我想将图片发送到 detail activity 以将此图片显示为封面图片。因此，我尝试使用以下代码来做到这一点。但我认为我在传递正确的图像值时犯了错误。如果有人帮我找出问题，那对我真的很有帮助。

问题已解决

适配器Class

 @Override
    public void onBindViewHolder(NewsHolder holder, int position) {
        final NewsModel currentNews = mNews.get(position);
        Picasso.with(holder.itemView.getContext());
        Picasso.with(holder.itemView.getContext()).load(currentNews.getTeaserImageSmall().getSrc()).into( holder.newsImage );        
        holder.newsHeadline.setText(currentNews.getTitle());
        holder.newsDate.setText(currentNews.getPostDate());
        holder.cardView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

               Intent i=new Intent(context,DetailNews.class);
                i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                i.putExtra("src",currentNews.getTeaserImageSmall().getSrc());
                i.putExtra("title",currentNews.getTitle());
                i.putExtra("body",currentNews.getBody());
                context.startActivity(i);
            }
        });

详情ActivityClass

Intent intent = getIntent();

    //RECEIVE DATA
    Log.e("_coverImage",""+_coverImage);
    String coverImage = intent.getStringExtra ("src");
    String heading=intent.getExtras().getString("title");
    //String newsDate=intent.getExtras().getString("date");
    String description=intent.getExtras().getString("body");

    //BIND DATA
   Picasso.with(this).load(coverImage ).into(_coverImage);
    _newsHeading.setText(heading);      
    _description.setText(description);

Answer 1

您正试图从您的意图中获取整数，但它是字符串。

//RECEIVE DATA
String coverImageSrc = intent.getStringExtra("src");

并再次用 Piccasso 加载它：

 Picasso.with(this).load( coverImageSrc ).into( _coverImage );

代替_coverImage.setImageResource(coverImage);

Answer 2

你的概念有点不清楚。您在适配器中传递字符串值并在 DeatilActivity class.

中接收整数

final NewsModel currentNews = mNews.get(position);
Picasso.with(holder.itemView.getContext());
Picasso.with(holder.itemView.getContext()).load(currentNews.getTeaserImageSmall().getSrc()).into( holder.newsImage ); //Image url 

holder.newsHeadline.setText(currentNews.getTitle());
holder.newsDate.setText(currentNews.getPostDate());
holder.cardView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

         Intent i=new Intent(context,DetailNews.class);
         i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
         i.putExtra("src",currentNews.getTeaserImageSmall().getSrc());
         i.putExtra("title",currentNews.getTitle());
         i.putExtra("body",currentNews.getBody());
         context.startActivity(i);
     }
 });

DeatilActivity.java

String coverImage = intent.getExtras().getString("src");
    String heading=intent.getExtras().getString("title");
    //String newsDate=intent.getExtras().getString("date");
    String description=intent.getExtras().getString("body");

//BIND DATA
//_coverImage.setImageResource(coverImage);   // Remove this line
Picasso.with(DetailActivity.this).load(coverImage ).into(_coverImage);
