Question

我有一个自定义列表，其中每行有一个图像视图，一个文本视图和两个按钮。

|```````````|  text box
|Image View |
|___________|  Button1 Button2

这是一行列表的布局。我的自定义AdapterClass是..

public class sublist extends ArrayAdapter<String> {

    private final Activity context;
    private final Vector<String> shortDisJornals;
    private final Vector<String> imageId1;

    public sublist(Activity context, Vector<String> s1,
            Vector<String> imageId1) {
        super(context, R.layout.sublist, s1);
        this.context = context;
        this.shortDisJornals = s1;
        this.imageId1 = imageId1;
        Log.d("image vector", ""+imageId1);

    }

    @Override
    public View getView(final int position, View view, ViewGroup parent) {
        LayoutInflater inflater = context.getLayoutInflater();
        View rowView = inflater.inflate(R.layout.sublist, null, true);
        TextView txtTitle = (TextView) rowView
                .findViewById(R.id.textViewjurnals);
        ImageView imageView = (ImageView) rowView
                .findViewById(R.id.imageViewJurnals);
        Button buyJurnals=(Button)rowView.findViewById(R.id.buttonjurnalsBuy);
        buyJurnals.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(getContext(), "sdsd"+position, 3000).show();
            }
        });
        Button detailsJurnalis=(Button)rowView.findViewById(R.id.buttonjrnalsDetails);
        txtTitle.setText(shortDisJornals.elementAt(position));
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
         .permitAll().build();

       StrictMode.setThreadPolicy(policy);
        String image = imageId1.elementAt(position);
         try { 
        Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new URL(
                 image).getContent());
          imageView.setImageBitmap(null);
               imageView.setImageBitmap(bitmap);
               // setContentView(image);
              } catch (MalformedURLException e) {
               e.printStackTrace();
              } catch (IOException e) {
               e.printStackTrace();
              }catch(Exception e){}


        return rowView;


     }
}

现在在我的主要活动中 -

lv = (ListView) findViewById(R.id.listView1);
titleVector = new Vector<String>();
imageUrl = new Vector<String>();
lv.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
    Toast.makeText(getApplicationContext(), "sd", 3000).show();

    }
});

但是当我点击按钮时，吐司剂量不显示

您正在为其中一个按钮设置onClickListener：buttonjurnalsBuy。单击此按钮应该可以工作。只需为另一个Button设置另一个Listener即可处理此按钮的点击。

如果单击列表中的整行，则会调用您在setOnItemClickListener中设置的侦听器。

如果为某些视图和OnItemClickListener设置单独的单击侦听器，则在用户单击其中一个视图时将调用单击侦听器。如果用户单击行中的其他位置，将调用OnItemClickListener。

如何知道从自定义列表中单击哪个按钮
