获得gridView中的一个图片对象及intent的传值

这个实际中很多，为了使用方面我就专门拿出来为了以后简单

 

public void onItemClick(AdapterView<?> parent, View v, int pos, long id) {

  String imagename = getResources().getResourceName((Integer)parent.getItemAtPosition(pos));

  imagename = imagename.substring(imagename.indexOf('/')+1,imagename.length());
  Toast.makeText(getApplicationContext(),"pic "+imagename, Toast.LENGTH_SHORT).show();
    
  Intent i = new Intent(this, OneImageViewer.class);
  i.putExtra("image",(Integer)parent.getItemAtPosition(pos));
  i.putExtra("imagename",imagename);
     startActivityForResult(i, CREATE_REQ);
 }

 

 

 

取其中的值

Bundle extras = getIntent().getExtras();
     if (extras != null) {
         Integer resloc = (Integer)extras.get("image");
         String imgname = (String)extras.get("imagename");
         if (resloc != null && imgname != null) {
             title.setText(imgname);
             img.setScaleType(ImageView.ScaleType.CENTER_CROP);
          img.setPadding(10,10,10,10);
             img.setImageResource(resloc);
         }
     }
