在list中存放键值对，使用list的set方法无法设置。

Question

问题

因为存放的是键值对，所以android studio 提示set（）里面放int 和Map
可是怎么写都会提示错误，求解答

上代码

package com.example.architectureescape;

import android.app.Activity;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.GridView;
import android.widget.SimpleAdapter;

import java.util.HashMap;
import java.util.Map;

import static android.content.ContentValues.TAG;

public class wall1Activity extends Activity {

GridView gridView;
SimpleAdapter simpleAdapter;
Adapp adapp = new Adapp();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_wall1);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    adapp.addint();
    gridView = (GridView) findViewById(R.id.grid1);
    simpleAdapter = new SimpleAdapter(wall1Activity.this,adapp.list,R.layout.simpleadapter,new String[]{"001"},new int[]{R.id.use1});
    gridView.setAdapter(simpleAdapter);
}

public void Onruler(View v) {

    for (int j = 0; j < 7; j++) {
        int t = adapp.list.get(j).get("001");
        if(t == R.mipmap.toolbar) {
            adapp.list.set(j,**<"001",R.mipmap.b>**);
            break;
        }
        Setimage();
    }
}

}

既然提示set（）里面放int 和Map，你的 adapp.list的元素应该是Map吧

if(t == R.mipmap.toolbar) {
Map map=list.get(j);
if(map!=null){
map.put("001",R.mipmap.b)//修改value
adapp.list.set(j,map);
break;
}

}
