推荐答案

不要设置列表视图监听器，如果你不想处理点击整个列表项。您可以设置个人看法监听器列表项像下面的例子给出：

Do not set listener on listview if you don't want to handle click on entire list item. You can set listener for individual view on list item like given in below example:

public class MyArrayAdapter extends ArrayAdapter<Map<String, String>> {

    private Context mContext;

    public MyArrayAdapter(Context context, int textViewResourceId,
            List<Map<String, String>> objects) {
        super(context, textViewResourceId, objects);
        mContext = context;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {

        if (convertView == null) {
            convertView = LayoutInflater.from(getContext()).inflate(
                    R.layout.list_row, null, false);
        }

        final Map<String, String> data = (Map<String, String>) getItem(position);

        ImageView imageView = (ImageView) convertView
                .findViewById(R.id.imageView);
        imageView.setImageResource(Integer.parseInt(data.get("image")));

        TextView textView = (TextView) convertView
                .findViewById(R.id.textViewTitle);
        textView.setText(data.get("name"));

        Button button = (Button) convertView
                .findViewById(R.id.buttonShow);

        button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                mContext.startActivity(new Intent(mContext,
                            DetailActivity.class).putExtra(EXTRA_IMAGE_URL,
                            data.get("url")));
            }
        });

        return convertView;
    }

}
