列表视图单击未启动

Question

我为包含文本和图像的listview创建了自定义适配器，在单击特定列表项时，我必须打开另一个活动，但我无法触发listview单击事件，下面是我的代码。

谢谢。

适配器

public class ImageAndTextAdapter extends ArrayAdapter<String> {
private LayoutInflater mInflater;
private Context myCtx;
private String[] mStrings;
private TypedArray mIcons;
private int mViewResourceId;
public ImageAndTextAdapter(Context ctx, int viewResourceId,
        String[] strings, TypedArray icons) {
    super(ctx, viewResourceId, strings);
    myCtx = ctx;
    mInflater = (LayoutInflater)ctx.getSystemService(
            Context.LAYOUT_INFLATER_SERVICE);
    mStrings = strings;
    mIcons = icons;
    mViewResourceId = viewResourceId;
}
@Override
public int getCount() {
    return mStrings.length;
}
@Override
public String getItem(int position) {
    return mStrings[position];
}
@Override
public long getItemId(int position) {
    return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    convertView = mInflater.inflate(mViewResourceId, null);
    ImageView iv = (ImageView)convertView.findViewById(R.id.option_icon);
    iv.setImageDrawable(mIcons.getDrawable(position));

    TextView tv = (TextView)convertView.findViewById(R.id.option_text);
    tv.setText(mStrings[position]);
    return convertView;
}
}

主要活动

public class OurWishingWellActivity extends ListActivity implements OnClickListener{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
   // setContentView(R.layout.list_view_image);
    Context ctx = getApplicationContext();
    Resources res = ctx.getResources();
    String[] options = res.getStringArray(R.array.reg_item_names);
    TypedArray icons = res.obtainTypedArray(R.array.reg_icons);
    setListAdapter(new ImageAndTextAdapter(ctx, R.layout.list_item,
            options, icons));
}
@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
}

}

尊敬的Aafag#

你已经写了如下列表视图的点击。

  @Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id);
    Toast.makeText(AdvancedListViewActivity.this, "working", Toast.LENGTH_SHORT).show();
    System.out.println("working!!!!!!!!!");
}

添加监听器

@Override

public View getView（int position、View convertView、ViewGroup父级）{convertView=mInfrater.inflate（mViewResourceId，null）；

ImageView iv = (ImageView)convertView.findViewById(R.id.option_icon);
iv.setImageDrawable(mIcons.getDrawable(position));

TextView tv = (TextView)convertView.findViewById(R.id.option_text);
tv.setText(mStrings[position]);

convertView.setOnClickListener（新的OnClickListener{

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            startActivity();

        }
    });
return convertView;

}
