在可扩展列表视图中膨胀tablelayout

Question

对于每个父视图，我的TableLayout不会膨胀一次。相反，TableLayout根本没有为第一个父级膨胀，为第二个父级膨胀一次，并为第三个父级膨胀两次。

有关为什么Tablelayout不会为每个父视图充气一次的任何想法？

主要类

package com.example.jbunn.gi;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ExpandableListAdapter;
import android.widget.ExpandableListView;

public class LeaderBoard extends Activity {

    ExpandableListView exv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_leader_board);
        exv = (ExpandableListView)findViewById(R.id.expandableListView);
        exv.setAdapter(new MyAdapter(this));
    }

}

MyAdapter类

package com.example.jbunn.gi;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseExpandableListAdapter;
import android.widget.EditText;
import android.widget.GridView;
import android.widget.TableLayout;
import android.widget.TextView;

public class MyAdapter extends BaseExpandableListAdapter{

    private Context context;
    private LayoutInflater mLi;

    String [] parentList = {"James", "Matt", "Rhodus"};

    public MyAdapter(Context context, LayoutInflater layoutInflater) {
    mContext = context;
    mLi = (LayoutInflater)context.getApplicationContext().getSystemService
            (Context.LAYOUT_INFLATER_SERVICE);
}


static class ViewHolderItem {
    TableLayout tl;
}
    @Override
    public int getGroupCount() {
        return parentList.length;
    }

    @Override
    public int getChildrenCount(int i) {
        return i;
    }

    @Override
    public Object getGroup(int i) {
        return i;
    }

    @Override
    public Object getChild(int i, int i2) {
        return null;
    }

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

    @Override
    public long getChildId(int i, int i2) {
        return 0;
    }

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

    @Override
    public View getGroupView(int i, boolean b, View view, ViewGroup viewGroup) {
        TextView tv = new EditText(context);
        tv.setText(parentList[i]);
        tv.setPadding(50,0,0,0);
        return tv;
    }

    @Override
    public View getChildView(int i, int i2, boolean b, View convertView, ViewGroup parent) {

    ViewHolderItem viewHolder;

    if(convertView ==null){
        // inflate the layout
        LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
        convertView = inflater.inflate(R.layout.childgridview, parent, false);
        // well set up the ViewHolder
        viewHolder = new ViewHolderItem();
        viewHolder.tl = (TableLayout) convertView.findViewById(R.id.childgridview);
        // store the holder with the view.
        convertView.setTag(viewHolder);

    }else{
        viewHolder = (ViewHolderItem) convertView.getTag();
    }

    return convertView;
}

    @Override
    public boolean isChildSelectable(int i, int i2) {
        return false;
    }

}

Answer 1

通过更改getChildrenCount方法以返回“1”而不是i，TableLayout为每个父级显示一次。
