Question

所以..我想创建一个列表视图，其视图将由自定义数组适配器处理。此列表视图的每个视图都有一个子文本视图。我想要做的是我想处理（启动一个intent）此文本视图的click事件，该事件位于列表视图中的视图中。我怎么做？我建议的代码会运行吗？

建议代码：

@Override
public view getView(int position, View convertView, View parent)
{
View v = convertView;
/*code…*/

TextView t = (TextView) v.findViewById(R.id.text_field);

t.setOnClickListener(new OnClickListener({
@Override
public void onClick(View v){
MediaPlayer mp = MediaPlayer.create(thisActivity.this, R.raw.sound);
mp.start();
}));

}

请参阅以下示例。

@Override
    public View getView(final int position, View view, final ViewGroup parent) {
        ViewHolder holder;
        LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        if (view != null) {
            holder = (ViewHolder) view.getTag();
        } else {
            view = inflater.inflate(R.layout.store_list_item, parent, false);
            holder = new ViewHolder(view);
            view.setTag(holder);
        }
        holder.storeName.setText(mShoppingLists.get(position).getName());
        holder.editButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                final FragmentManager manager = ((Activity) mContext).getFragmentManager();
                FragmentTransaction transaction = manager.beginTransaction();
                ShoppingListEditFragment shoppingListEditFragment =
                        ShoppingListEditFragment.newInstance(mShoppingLists.get(position).getId());
                transaction.replace(R.id.container, shoppingListEditFragment, "shoppinglistedit");
                transaction.addToBackStack(null);
                transaction.commit();
            }
        });

        holder.handle.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                ((DynamicListView) parent).onHandleLongClickListener(new DragEvent());
                return true;
            }
        });
        return view;
    }

如果您想处理listview项目的click事件，请输入以下代码：

    /*Inside the onCreate method of your activity class which displays the list
    ......*/
        ListView l = (ListView)findViewById(R.id.list);
        CustomAdapter adapter = new CustomAdapter(this, 0, list, R.color.category_numbers);
        l.setAdapter(adapter);
        l.setOnItemClickListener(new AdapterView.OnItemClickListener({
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long 
        id) {
        /*your code*/
        }
    });

要捕获listview项目中子元素的click事件，还需要在子元素上设置focusable="false"，在Listview本身设置focusable="true"。

除此之外，代码看起来正确。因此，请尝试设置focusable和focusableInTouchMode参数。

如何处理列表视图项视图的子视图的单击事件？
