android - 使用按钮 onClick 获取图像

Question

我正在尝试获取图像并希望使用`Button.onClickListener()

将其放入HashMap

我确定我在这里做错了:

   String s_image = imgv.toString();

我想在这里我应该使用 ImageView 代替 String，但怀疑需要编写什么代码以及如何编写代码

Single.java代码:

public class Single extends Activity {

public static final String LOG_TAG = "Single";

public static final String TAG_TITLE = "title";
public static final String TAG_IMAGE = "image";

String s_title, s_image; 

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.information_product);

    Intent in = getIntent();
    String title = in.getStringExtra(TAG_TITLE);        
    String image = in.getStringExtra(TAG_IMAGE);
    Log.d(Single.LOG_TAG, "ImageURL :: " + image);


    final ImageLoader imageLoader = new ImageLoader(getApplicationContext());

    final ImageView imgv = (ImageView) findViewById(R.id.single_thumb);
    final TextView txttitle = (TextView) findViewById(R.id.single_title);

    txttitle.setText(title);
    imageLoader.DisplayImage(image, imgv);

    Button mImgAddCart = (Button) findViewById(R.id.button_add);
    mImgAddCart.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub

            s_title = txttitle.getText().toString();
            Log.d(Single.LOG_TAG, "Title :: " + s_title);
            s_image = imgv.toString();
            Log.d(Single.LOG_TAG, "Image :: " + s_image);

            if (Session.item_data.size() <= 0) {
                HashMap<String, String> h_obj = new HashMap<String, String>();
                h_obj.put(TAG_TITLE, s_title);
                h_obj.put(TAG_IMAGE, s_image);
                Session.item_data.add(h_obj);                       
            }           
        }
    });

Button mImgAddCart = (Button) findViewById(R.id.button_add); 
mImgAddCart.setOnClickListener(new OnClickListener() { 

public void onClick(View v) { 
// TODO Auto-generated method stub 

s_title = txttitle.getText().toString(); 
Log.d(Single.LOG_TAG, "Title :: " + s_title);   
image = in.getStringExtra(TAG_IMAGE); 
if (Session.item_data.size() <= 0) { 
HashMap<String, String> h_obj = new HashMap<String, String>(); 
h_obj.put(TAG_TITLE, s_title); 
h_obj.put(TAG_IMAGE, image); 
Session.item_data.add(h_obj);   
}   
} 
});
