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);
???????? }
???? }
