發送列表項目的靜態圖像和文本到下一個活動，同時點擊在Android的列表活動

Question

我有一個列表活動，其中我顯示的圖像和文本在一行。

圖像是靜態的，它們被放置在可繪製的文件夾中。

我想在下一個活動中打印圖像和文本，同時單擊列表項目。我可以成功發送下一個活動的文本視圖。但是我發現將圖像發送到下一個窗口很困難。因爲這些是靜態的。

任何人都可以幫助我解決這個問題。提前致謝。

 public class Myimage extends ListActivity { 

     private LayoutInflater mInflater; 
     static Vector<RowData> data = new Vector<RowData>(); 
     RowData rd; 
     static boolean fromCategory = false; 
     static final String[] title = new String[] { 
       "One", "Two", "Three "}; 

     private Integer[] img = { 
      R.drawable.i,R.drawable.im,R.drawable.ima}; 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     mInflater = 

(LayoutInflater) getSystemService(
    Activity.LAYOUT_INFLATER_SERVICE); 

    for(int i=0;i<title.length;i++){ 
    try { 
     rd = new RowData(i,title[i]); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     data.add(rd); 
    } 
     CustomAdapter adapter = new CustomAdapter(this, R.layout.list, 
             R.id.title, data); 
     setListAdapter(adapter); 
     getListView().setTextFilterEnabled(true); 

    // This is the List Item Click method which i should work to send the image on next activity. 




    public void onListItemClick(ListView parent, View v, int position, 
       long id) { 
      Intent intent = new Intent(this,Second.class); 
      intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 






     } 
    public class RowData { 

       protected int mId; 
       protected String mTitle; 

       RowData(int id,String title){ 
       mId=id; 
       mTitle = title; 

      } 
       public void setTitle(String title) { 
       this.mTitle = title.trim(); 
      } 

       public String getTitle() { 
       return mTitle; 
      } 
       public void setId(int i){ 
        this.mId=i; 
        } 
       public int getId(){ 
        return mId; 
       } 


       @Override 
       public String toString() { 
         return mId+" "+mTitle; 
       } 
     } 




      private class CustomAdapter extends ArrayAdapter<RowData> { 
      public CustomAdapter(Context context, int resource, 
           int textViewResourceId, List<RowData> objects) {    
     super(context, resource, textViewResourceId, objects); 
     } 
       @Override 
       public View getView(int position, View convertView, ViewGroup parent) { 
       ViewHolder holder = null; 
       TextView title = null; 

       ImageView i11=null; 
       RowData rowData= getItem(position); 
       if(null == convertView){ 
        convertView = mInflater.inflate(R.layout.list, null); 
        holder = new ViewHolder(convertView); 
        convertView.setTag(holder); 
     } 
        holder = (ViewHolder) convertView.getTag(); 
        title = holder.gettitle(); 
        title.setText(rowData.mTitle); 

        i11=holder.getImage(); 
        i11.setImageResource(img[rowData.mId]); 
        return convertView; 
     } 
        private class ViewHolder { 
        private View mRow; 
        private TextView title = null; 

        private ImageView i11=null; 
        public ViewHolder(View row) { 
        mRow = row; 
     } 
       public TextView gettitle() { 
        if(null == title){ 
         title = (TextView) mRow.findViewById(R.id.title); 
         } 
        return title; 
       }  

       public ImageView getImage() { 
        if(null == i11){ 
          i11 = (ImageView) mRow.findViewById(R.id.img); 
               } 
         return i11; 
       } 
      } 
      } }

您應該使用Bundle類發送文本和圖像。我建議你發送imageid（R.id.imageID）而不是發送到ImageView。

//Use It for setting value of Bundle variable 
    Intent intent = new Intent(CourtDetailActivity.thisDrivingDirection.class); 
    intent.putExtra("CourtId", courtId); 
    startActivity(intent); 
    //Use It for geting value of Bandle variable 
    Bundle extras = getIntent().getExtras(); 
    courtId = extras != null ? extras.getString("ImageId") : ""; 

    //You just copy and past given blow code in your code 
    public void onListItemClick(ListView parent, View v, int position, 
      long id) { 
     Intent intent = new Intent(this,Second.class); 

     intent.putExtra("ImageId", ""+img[position]); 
     startActivity(intent); 

    } 

我希望這對您有所幫助
