java - setOnClickListener 未使用自定义适配器和自定义 ListView 触发

Question

我花了几个小时解决一个问题，但仍然无法解决。当我单击 ListView 中的项目时，HotelOverviewFragment 中的 setOnClickListener 不会触发。但是，setOnClickListener 确实可以在我的自定义适配器 (NowArrayAdapter) 中工作。

我的问题是:为什么 setOnClickListener 在 HotelOverviewFragment(显示 ListView 的类)中不起作用？

这是我尝试过的列表:

• 在 hotel_row_layout.xml 和fragment_hotel_overview.xml 中设置 android:focusable="false"、android:focusableInTouchMode="false"、android:descendantFocusability="blocksDescendants"。

• 将 android:clickable 设置为 true 和 false。两者都不起作用。

• 从 BaseAdapter 实现更改为 arrayAdapter。

• 我在 HotelOverviewFragment 中尝试了不同的监听器:setOnClickListener、setOnItemClickListener、setOnItemSelectedListener 和 setOnTouchListener。不幸的是，这些都不适合我。

这是我的代码:

自定义适配器

    public class NowArrayAdapter extends ArrayAdapter<String> {

private Context context;
private ArrayList<String> values;
private Typeface typeface;
private static Hashtable fontCache = new Hashtable();
private LayoutInflater inflater;
private TextView item;

public NowArrayAdapter(Context context, ArrayList<String> commandsList) {
    super(context, R.layout.hotel_row_layout, commandsList);
    this.context = context;
    values = new ArrayList<String>();
    values.addAll(commandsList);

    typeface = getTypeface(this.context, "fonts/Roboto-Light.ttf");
    inflater = LayoutInflater.from(this.context);
}

static Typeface getTypeface(Context context, String font) {
    Typeface typeface = (Typeface)fontCache.get(font);
    if (typeface == null) {
        typeface = Typeface.createFromAsset(context.getAssets(), font);
        fontCache.put(font, typeface);
    }
    return typeface;
}

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

    String myText = getItem(position);

    if(convertView == null) {
        convertView = inflater.inflate(R.layout.hotel_row_layout, parent, false);

        item = (TextView) convertView.findViewById(R.id.maps_button);
        item.setTypeface(typeface);

        convertView.setTag(item);
    } else {
        item = (TextView) convertView.getTag();
    }

    item.setText(myText);
    //myListItem.descText.setTextSize(14);

    convertView.setOnClickListener(new View.OnClickListener() {
        // WORKS!
        @Override
        public void onClick(View view) {
            Log.d("click", "Don't look at me!");
        }
    });

    return convertView;
   }

}

fragment

    public class HotelOverviewFragment extends Fragment {
private static Hashtable fontCache = new Hashtable();

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_hotel_overview, container, false);
    ListView list = (ListView) v.findViewById(android.R.id.list);

    // Set up listview and buttons
    setUp(v, list);

    // Inflate the layout for this fragment
    return v;
}

static Typeface getTypeface(Context context, String font) {
    Typeface typeface = (Typeface)fontCache.get(font);
    if (typeface == null) {
        typeface = Typeface.createFromAsset(context.getAssets(), font);
        fontCache.put(font, typeface);
    }
    return typeface;
}

public void setUp(View v, ListView l){
    TextView address = (TextView) v.findViewById(R.id.content);
    TextView header = (TextView) v.findViewById(R.id.header);
    TextView hotelName = (TextView) v.findViewById(R.id.hotelName);
    Typeface typeface = getTypeface(getActivity(), "fonts/Roboto-Light.ttf");

    address.setText("some street \nZipCode, City \nCountry \nEmail \nphoneNumber");
    address.setTypeface(typeface);

    header.setText("Hotel info");
    header.setTypeface(typeface);
    header.setTextSize(20);

    hotelName.setText("Hotel name");
    hotelName.setTypeface(typeface);

    // Set up button
    ArrayList<String> n = new ArrayList<String>();
    n.add(0, "More info");

    // Show button
    NowArrayAdapter adapter = new NowArrayAdapter(getActivity(), n);

    l.setAdapter(adapter);

    // THIS IS THE STUFF I'VE BEEN TRYING
    try {
        l.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("click", "Success");
            }
        });

        l.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Log.d("click", "Success");
            }
        });

        l.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                Log.d("click", "Success");
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });

        l.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.d("click", "Success");

                return false;
            }
        });
    }catch (Exception e){
        Log.d("click", e + "");
    }
}

提前致谢。

Answer 1

感谢 Daniel Nugent 的建议，我让它工作起来了。删除 convertView.setOnClickListener() 是答案的一部分。我认为它阻止了 HotelOverviewFragment 中的其他监听器。

我的下一个错误是我在 ListView 上使用 setOnClickListener 进行测试。setOnClickListener 应该用于按钮而不是 ListView。因此，删除 setOnClickListener 后，所有其他监听器都开始工作。

感谢您的宝贵时间。
