java.lang.ClassCastException : android. widget.LinearLayout$LayoutParams 无法转换为 android.widget.AbsListView$LayoutParams

Question

我正在使用 BaseExpandableListAdapter，如下所示。我没有传递列表，而是直接传递 View 作为子数据。并且子计数始终返回为 1。因为每个标题只有一个 View 。

public class TaxAdapter extends BaseExpandableListAdapter{

    private Context _context;
    private ArrayList<String> _listDataHeader; 
    private HashMap<String, View> _listDataChild;


    public TaxAdapter(Context context, ArrayList<String> taxListDataHeader,
            HashMap<String, View> taxListDataChild) {
        this._context = context;
        this._listDataHeader = taxListDataHeader;
        this._listDataChild = taxListDataChild;
    }

    @Override
    public int getGroupCount() {
        return this._listDataHeader.size();
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        return 1;
    }

    @Override
    public Object getGroup(int groupPosition) {
         return this._listDataHeader.get(groupPosition);
    }

    @Override
    public Object getChild(int groupPosition, int childPosition) {
         return this._listDataChild.get(this._listDataHeader.get(groupPosition));
    }

    @Override
    public long getGroupId(int groupPosition) {
         return groupPosition;
    }

    @Override
    public long getChildId(int groupPosition, int childPosition) {
        return childPosition;
    }

    @Override
    public boolean hasStableIds() {
        return false;
    }

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded,
            View convertView, ViewGroup parent) {
        String headerTitle = (String) getGroup(groupPosition);
        if (convertView == null) {
            LinearLayout earningsContainer = new LinearLayout(_context);
            LayoutInflater inflator = ((Activity)_context).getLayoutInflater();
            convertView = inflator.inflate(R.layout.row_tax_explv_title,
                    earningsContainer, false);
            ((TextView) convertView.findViewById(R.id.explvTaxTitleText)).setText(headerTitle);
        }

        return convertView;
    }

    @Override
    public View getChildView(int groupPosition, int childPosition,
            boolean isLastChild, View convertView, ViewGroup parent) {

        return (View)getChild(groupPosition, childPosition);

    }

    @Override
    public boolean isChildSelectable(int groupPosition, int childPosition) {
        return false;
    }

}

从 Activity 传递的数据如下 -

    ArrayList<String> TaxListDataHeader = new ArrayList<String>();
    HashMap<String, View> TaxListDataChild = new HashMap<String, View>();

TaxListDataHeader.add("Movie Shows");
TaxListDataChild.put("Movie Shows", moviesContainerView);
TaxListDataHeader.add("Theatre Shows");
TaxListDataHeader.add("Theatre Shows", theatreContainerView);

movieContainerView 和 theareContainerView 是两个自定义的膨胀线性布局。就像这样

LayoutInflater inflator = ((Activity) context).getLayoutInflater();
        View row = inflator.inflate(R.layout.row_movie_data,
                movieMainContainer, false);

        ((TextView) row.findViewById(R.id.txtEmpInfoPopUpTitle)).setText(key);
        ((TextView) row.findViewById(R.id.txtEmpInfoPopUpValue)).setText(value);
        return row;

我收到标题中的错误，但日志没有指定任何文件名。 请指出可能发生错误的位置。请建议可以做什么。

编辑: 我尝试用这样的 ListView 包装线性布局，

TaxListDataChild.put("Theatre Show", (new ListView(context)).addView(theatrerowContainer, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

但是第二个参数好像是void。

我正在像这样使用其他线性布局行填充 xml 中的“新 Linearlayout”(earningsContainer)。

for (int i = 0; i < taxMainObject.getTaxEarnings().size(); i++) {
        earningsContainer.addView(getTaxEarningsRow(taxMainObject
                    .getTaxEarnings().get(i)));
            totalEarnings += taxMainObject.getTaxEarnings().get(i)
                    .getTotalAmount();
        }
        earningsContainer.addView(getTaxTotalRow("GROSS TOTAL SALARY",
                totalEarnings + ""));

行的 xml 是 -

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="right"
    android:orientation="horizontal"
    android:background="#ffeeeeee" >


   <TextView
        android:id="@+id/txtTotalText"
        android:layout_width="180dp"
        android:layout_height="wrap_content"
        android:layout_marginLeft="15dp"
        android:textAppearance="@android:attr/textAppearanceSmall"
        android:textColor="#736F6E"
        android:textSize="14sp"
        android:textStyle="bold|italic" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:gravity="right|center_vertical"
        android:orientation="horizontal"
        android:padding="2dp" >

        <TextView
            android:id="@+id/txtTotalValue"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:textAppearance="@android:attr/textAppearanceSmall"
            android:textColor="#736F6E"
             android:gravity="right"
            android:textSize="14sp"
            android:layout_weight="1"
            android:textStyle="italic" />
        </LinearLayout>
</LinearLayout>

Answer 1

虽然这与你的java无关，但我仍然遇到同样的错误。我的类(class)中有“extends AppCompatActivity”，但是当我将其替换为“Extends Activity”时，错误已解决。希望这对其他人有帮助，因为我在这方面被困了三个小时。很高兴为您提供帮助
