listview嵌套listview数据显示问题

2个问题：
1、listview嵌套listview,只显示一行内容：
解决方法：自定义listview

public class ChildListView extends ListView {
    public ChildListView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    public ChildListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }

    public ChildListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }

}

2、第二个listview数据覆盖显示，点击后实为假数据；

 mholder.lv_1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Intent intent = new Intent(context, DALLES_Detail.class);

                TextView tv_rf = view.findViewById(R.id.tv_rf);
                TextView tv_sc = view.findViewById(R.id.tv_sc);
                intent.putExtra("rf",tv_rf.getText().toString());
                intent.putExtra("sc",tv_sc.getText().toString());
// 实时到点击位置数据
                intent.putExtra("titlename",name);
               context.startActivity(intent);
            }
        });
