如何使半视图不可点击

Question

嘿，对不起，我的英语不好。。。

我的 ListFragment 中有一个 ListView，带有自定义适配器。在我的布局中，我有一个按钮。按钮和整个项目/行是可单击的。我用android：clickable=“false”为ImageButton实现了这一点。正如您在 getView（） 方法中看到的，我捕获了一个单击操作。

public class ArrayAdapterListView extends BaseAdapter {

private final ArrayList<String> arrayList;
private final Context context;
private ArrayList<String> pWListName, pW2ListName;
private ArrayList<Integer> pWListIconID;
private ListPopupWindow listPopupWindow, listPopupWindow2;
private boolean isItemHold = false;
ViewHolder viewHolder = new ViewHolder();

public ArrayAdapterListView(ArrayList<String> list, Context context){
    this.arrayList = list;
    this.context = context;
}


@Override
public int getCount() {
    return arrayList.size();
}

@Override
public Object getItem(int position) {
    return arrayList.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@SuppressLint({"ClickableViewAccessibility", "InflateParams"})
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = convertView;
    if(view == null){
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = inflater.inflate(R.layout.fragment_file_browser_row, null);
        viewHolder = createViewHolder(view);
        view.setTag(viewHolder);
    }else{
        viewHolder = (ViewHolder) view.getTag();
    }

    viewHolder.textView.setText(arrayList.get(position));

    if(selectedItemIndex.isEmpty()) {
        for (int i = 0; i < getCount(); i++) {
            selectedItemIndex.add(null);
        }
    }
    if(isItemSelectedOnIndex.isEmpty()){
        for (int i = 0; i < getCount(); i++){
            isItemSelectedOnIndex.add(false);
        }
    }

    view.setOnTouchListener((v, event) -> {
        viewHolder.imageView = v.findViewById(R.id.checkedImage);

        if(event.getAction() == MotionEvent.ACTION_DOWN){
            index = position;
            if(L)Log.d("fileBrowser", "index: " + index);
        }

        //Auswahl betätigen
        if (event.getAction() == MotionEvent.ACTION_UP && isItemHold && !isItemSelectedOnIndex.get(index)) {
            isItemHold = false;
            isItemSelectedOnIndex.set(index, true);
            if(L)Log.d("fileBrowser", "Auswahl getätigt: isItemHold = false; isItemSelected = true");
            selectedItemIndex.set(index, index);
            if(L)Log.d("fileBrowser", "getätigte Auswahl: " + selectedItemIndex);

            viewHolder.imageView.setImageResource(R.drawable.ic_checkbox_checked);
        }
        //Auswahl löschen
        else if(event.getAction() == MotionEvent.ACTION_UP && isItemSelectedOnIndex.get(index)){
            isItemHold = false;
            selectedItemIndex.set(index, null);
            if(L)Log.d("fileBrowser", "getätigte Auswahl2: " + selectedItemIndex);
            isItemSelectedOnIndex.set(index, false);
            if(L)Log.d("fileBrowser", "Auswahl weg gemacht: isItemSelected = false");

            viewHolder.imageView.setImageResource(R.drawable.ic_checkbox);
        }
        return false;
    });

    view.setOnLongClickListener(v -> {
        if(!isItemHold) {
            isItemHold = true;
            if(L)Log.d("fileBrowser", "Long Click getätigt: isItemHold = true");
        }
        return false;
    });

    listPopupWindow = new ListPopupWindow(context);
    listPopupWindow2 = new ListPopupWindow(context);
    viewHolder.imageButton.setOnTouchListener((v, event) -> {
        listPopupWindow.dismiss();
        showListPopupWindow(v);
        return false;
    });

    return view;
}

这是我的布局：

现在我想知道你是否可以在不选择整个视图的情况下点击按钮，但仍然注意到背景上的点击（我知道我在列表视图中的位置）。在我点击ImageButton以外的任何其他按钮时，我会对我的代码的任何其他解决方案保持开放，直到我有可见的反馈。可见的触感应该覆盖整个项目。

Answer 1

我已经自己解决了问题。我已经使ImageButton和ImageView再次可点击和聚焦，并找到了一个解决方案，我仍然可以获得项目位置(即使我没有点击它):

View parentRow = (View) v.getParent();
ListView listView = (ListView) parentRow.getParent();
index = listView.getPositionForView(parentRow);

来源：获取列表视图项在按钮上的位置单击

现在我可以处理的位置，而无需点击行了。
