我有一个列表片段显示我的自定义列表项，其中包含包含图像和文本等的相对布局。
<?xml version="1.0" encoding="utf-8"?>

我正在尝试设置一个 OnItemClickListener，因此当用户单击列表项上的任意位置时，就会启动一个新的 Intent。
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//Populate list view with array objects
adapter = new HomeListItemAdapter(items, getActivity());
listView = getListView();
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Toast toast = Toast.makeText(listView.getContext(), "CLICKED", Toast.LENGTH_SHORT);
toast.show();
}
});
}
我正在尝试如上所示，但似乎无法让 OnItemClickListener 工作（目前仅使用 Toast 而不是 Intent 进行测试）。我哪里错了？谢谢
编辑：添加了自定义列表适配器代码
public class HomeListItemAdapter extends BaseAdapter {
private List<HomeListItem> items;
private Context context;
private int numItems = 0;
public HomeListItemAdapter(final List<HomeListItem> items, Context context) {
this.items = items;
this.context = context;
this.numItems = items.size();
}
public int getCount() {
return numItems;
}
public HomeListItem getItem(int position) {
return items.get(position);
}
public long getItemId(int position) {
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
// Get the current list item
final HomeListItem item = items.get(position);
// Get the layout for the list item
final RelativeLayout itemLayout = (RelativeLayout) LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
// Set the the item picture(s)
ImageView itemImage = (ImageView) itemLayout.findViewById(R.id.item_image);
itemImage.setImageDrawable(item.getItemPic());
//Set the profile picture / source picture
ImageView sourceImage = (ImageView) itemLayout.findViewById(R.id.source_image);
sourceImage.setImageDrawable(item.getSourcePic());
// Set the text label as defined in our list item
TextView itemDesc = (TextView) itemLayout.findViewById(R.id.item_description);
AssetManager am = context.getAssets();
Typeface font = Typeface.createFromAsset(am, "Raleway-Thin.ttf");
itemDesc.setTypeface(font);
itemDesc.setText(item.getText());
return itemLayout;
}
}
