鉴于下面的代码,是否可以在阵列行星中使用图像而不是文本？

    Spinner s = (Spinner) findViewById(R.id.spinner);    
    ArrayAdapter adapter = ArrayAdapter.createFromResource(            
            this, R.array.planets, android.R.layout.simple_spinner_item);    
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);    
    s.setAdapter(adapter);

和

    <string name="planet_prompt">Choose a planet</string>
    <string-array name="planets">        
        <item>Mercury</item>
        <item>Venus</item>
        <item>Earth</item>        
        <item>Mars</item>        
        <item>Jupiter</item>        
        <item>Saturn</item>        
        <item>Uranus</item>        
        <item>Neptune</item>    
    </string-array>    

我在向以下代码实现异步图像加载器时遇到问题.我在网上看了一些关于它的帖子,我想我理解它背后的逻辑,但我似乎没有实现它.

下面的代码是我用来简单地加载listview中的图像.

public class MyCustomAdapter extends ArrayAdapter<RSSItem> {
   Bitmap bm;

   public MyCustomAdapter(Context context, int textViewResourceId, List<RSSItem> list) {
      super(context, textViewResourceId, list); 
   }

   @Override
   public View getView(int position, View convertView, ViewGroup parent) {
      // TODO Auto-generated method stub
      BitmapFactory.Options bmOptions;
      bmOptions = new BitmapFactory.Options();
      bmOptions.inSampleSize = 1;
      bm = LoadImage(myRssFeed.getList().get(position).getDescription(), bmOptions);

      View row = convertView;

      if(row == null) {
         LayoutInflater inflater = getLayoutInflater();
         row = inflater.inflate(R.layout.rsslist, parent, false); 
      }

      TextView listTitle = (TextView)row.findViewById(R.id.listtitle);
      listTitle.setText(myRssFeed.getList().get(position).getTitle());
      ImageView listDescription = (ImageView)row.findViewById(R.id.listdescription);
      listDescription.setImageBitmap(bm);
      TextView listPubdate …

我正在使用以下代码,它只放大loadData.如何在里面放大图像？先感谢您!

WebView web = (WebView) findViewById(R.id.myid);    
web.loadUrl("file:///android_asset/image.jpg");
web.getSettings().setBuiltInZoomControls(true);
web.setBackgroundColor(0);
web.setVisibility(ImageView.VISIBLE);
web.setBackgroundResource(R.drawable.myimage);
