Question

我试图显示一个自定义列表。我正在将一个字符串数组传递给class customAdapter。当我尝试访问getLayoutInflater时无法识别？我该如何解决这个问题

package com.parse.starter;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;

import java.util.ArrayList;

public class CustomAdapter extends BaseAdapter {
    ArrayList<String> descriptions;
     public CustomAdapter(final ArrayList<String> description) {
         descriptions=description;    
    }

    @Override
    public int getCount() {

        return descriptions.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View view, ViewGroup parent) {    
       view=getLayotInflater(R.layout.rowcourses,null);   
        return null;
    }
}

在这里，更改此构造函数

private Context context;
public CustomAdapter(Context context, final ArrayList<String> description) {
         descriptions=description;  
         context = context;  
    }

并对此进行修改

@Override
    public View getView(int position, View view, ViewGroup parent) {  
   // so you would require an Inflater service which will load/inflate the layout, and to use service,
   // you need to have access to context, which you can get it from the constructor by passing it from your host class.

     LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

              View aView=inflater.inflate(R.layout.rowcourses, parent,false);
  // once you load the view, you need to return that, in your case you were returning null   
                return aView;
            }

如何修复Layoutinflator找不到错误？
