使用可扩展的标题网格视图在Android L上工作正常，但在设备上崩溃<= 4.4

Question

我在应用程序中使用expandableheaderridview在滚动视图中添加gridview。它在安卓L上运行完全正常，但该应用程序在设备上崩溃<=4.4.4.无法弄清楚为什么会发生这种情况。我的布局文件

ExpandableHeaderGridView文件

      package com.hj.app.widgets;
     import android.content.Context;
     import android.util.AttributeSet;
     import android.view.ViewGroup;
     import android.widget.GridView;
 public class ExpandableHeightGridView extends GridView {
boolean expanded = false;
public ExpandableHeightGridView(Context context) {
    super(context);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs) {
    super(context, attrs);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs,
        int defStyle) {
    super(context, attrs, defStyle);
}
public boolean isExpanded() {
    return expanded;
}
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    if (isExpanded()) {
        // Calculate entire height by providing a very large height hint.
        // View.MEASURED_SIZE_MASK represents the largest height possible.
        int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    } else {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}
public void setExpanded(boolean expanded) {
    this.expanded = expanded;
}

}

它在可扩展高度网格视图的行崩溃

   super.onMeasure(widthMeasureSpec, expandSpec); 

在带有isExpandedtrue的onmesure中出现以下错误。

错误：

    java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.widget.AbsListView$LayoutParams

不明白为什么会发生这种事。请帮忙！！！！！

第1版：我的适配器类，用于在网格中填充数据。

    package com.hj.app.adapters;
    import android.content.Context;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.BaseAdapter;
    import android.widget.FrameLayout;
    import android.widget.FrameLayout.LayoutParams;
    import android.widget.ImageView;
    import android.widget.TextView;
    import com.hj.app.R;

  public class HJRelatedItemGridAdapter extends BaseAdapter {
   Context mContext;
   int itemHeight;
public HJRelatedItemGridAdapter(Context context) {
    this.mContext = context;
}
@Override
public int getCount() {
    return 10;
}
public void setItemHeight(int itemHeight) {
    this.itemHeight = itemHeight;
}
@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return position;
}
@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
        convertView = LayoutInflater.from(mContext).inflate(
                R.layout.hj_related_items_grid_item_layout, parent, false);
        GridItemHolder holder = new GridItemHolder(convertView);
        convertView.setTag(holder);
    }
    GridItemHolder holder = (GridItemHolder) convertView.getTag();
    LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT,
            itemHeight);
    holder.parentLayout.setLayoutParams(lp);
    return convertView;
}
public class GridItemHolder {
    ImageView img;
    TextView titleText;
    FrameLayout parentLayout;
    /**
     * @param itemView
     */
    public GridItemHolder(View view) {
        img = (ImageView) view.findViewById(R.id.hj_grid_image);
        titleText = (TextView) view.findViewById(R.id.hj_grid_title_text);
        parentLayout = (FrameLayout) view.findViewById(R.id.hj_grid_parent);
    }
}
}

Answer 1

在适配器类中，而不是导入

import android.widget.FrameLayout.LayoutParams;

进口

import android.widget.AbsListView.LayoutParams;

因为网格视图项的父项是AbsListView，而不是FrameLayout。
