Question

我正在关注本教程android custom listview with image and text using volley（原始项目文件可以找到here），我修改了代码，以便在用户点击某个项目时显示有关单个项目的更多信息。

这是.... // Parsing json for (int i = 0; i < response.length(); i++) { try { movie.setTitle(obj.getString("title")); // this is the image path in the json file movie.setThumbnailUrl(obj.getString("image")); ...... listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { String _movieTitle = ((TextView) view.findViewById(R.id.title)).getText().toString(); Intent myIntent = new Intent (MainActivity.this, MoreInfoActivity.class); // send movie title myIntent.putExtra("title", _movieTitle) ; // the problem is here, I cannot send the image path //myIntent.putExtra("image", R.id.image) ; startActivity(myIntent) ; } });

的部分内容

custom adapter

if (imageLoader == null) imageLoader = AppController.getInstance().getImageLoader(); NetworkImageView thumbNail = (NetworkImageView) convertView.findViewById(R.id.thumbnail); TextView title = (TextView) convertView.findViewById(R.id.title); // getting movie data for the row Movie m = movieItems.get(position); // thumbnail image thumbNail.setImageUrl(m.getThumbnailUrl(), imageLoader);内容：

moredetailsactivity.java

我的public class moredetailsactivity extends Activity { private TextView title, image; private String _title,_rating,_image; public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.movie_details); title = (TextView) findViewById(R.id.title); image = (TextView) findViewById(R.id.image); Intent i = getIntent(); if (i.getExtras() != null) { _title = (String) i.getExtras().get("title"); _image = (String) i.getExtras().get("image"); } title.setText(_title); ..... }：

mainactivity

我想在moredetailsactivity的{{1}}中显示相同的缩略图。

这会显示main_activity.xml

中的图片

<com.android.volley.toolbox.NetworkImageView
        android:id="@+id/thumbnail"
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:layout_alignParentLeft="true"
        android:layout_marginRight="8dp" />

但相同的代码在more_details.xml上没有显示任何内容。

Answer 1

private JSONArray movieList;
    .......

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            String _movieTitle = ((TextView) view.findViewById(R.id.title)).getText().toString();

            Intent myIntent = new Intent (MainActivity.this, MoreInfoActivity.class);

            String image = movieList.get(position).getString("image");


            // send movie title
            myIntent.putExtra("title", _movieTitle) ;
            myIntent.putExtra("image", _movieTitle) ;

            // the problem is here, I cannot send the image path            
            //myIntent.putExtra("image", R.id.image) ;
            startActivity(myIntent) ;
          }
        });
