Android 未执行MClickListener

在main活动中，我有一个带有剪切适配器的

listView

，适配器类扩展了

BaseAdapter

在mainActivity中，我试图在剪辑某个项目时显示消息，因此我调用了

OnItemClickListener

，并在其中显示了一个

toast

。但当我点击一个项目时，什么也不显示

请让我知道我错过了什么

主要活动：

private void setUpListView() {
    // TODO Auto-generated method stub
    this.topicsList = new ArrayList<String>();

    for (int i = 0; i < this.topics.length; i++) {
        this.topicsList.add(topics[i]);
    }

    this.adapter = new listViewAdapter(getApplicationContext(), this.topicsList);
    this.listView.setAdapter(adapter);
    this.listView.setOnItemClickListener(listViewitemListener);
}
....
....
private OnItemClickListener listViewitemListener = new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        // TODO Auto-generated method stub
        Toast.makeText(getApplicationContext(), "item clicked", Toast.LENGTH_SHORT).show();

    }
};

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub


    if (convertView == null) {
        LayoutInflater layoutinflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = layoutinflater.inflate(R.layout.list_items_layout, null);
    }

    TextView tv = (TextView) convertView.findViewById(R.id.tvlist_topic);
    CheckBox cb = (CheckBox) convertView.findViewById(R.id.cbList_hook);
    ImageView iv = (ImageView) convertView.findViewById(R.id.ivList_delete);

    tv.setText(this.arrayList.get(position));

    iv.setOnClickListener(new OnClickListener() {

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

        }
    });

    return convertView;
}

将

android:genderantfocusability=“blocksDescendants”

添加到

列表项目布局的根目录中
