安卓，新建simpleAdapter报错，求大神看看

Question

在girdview中添加simpleAdapter,为什么新建SimpleAdapter的时候会报错？

我的代码如下：

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity"
android:orientation="vertical">

<GridView
    android:id="@+id/gridview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>






</LinearLayout>

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".activity"
android:orientation="vertical">

<ImageView 
    android:id="@+id/image"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

</LinearLayout>

package com.example.test4;

import android.os.Bundle;
import android.widget.*;
import java.util.*;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

SimpleAdapter s=null;
GridView grid=null;
List<Map<String,Integer>> list=null;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    grid=(GridView)super.findViewById(R.id.gridview);
    initAdapter();
    grid.setAdapter(s);
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public void initAdapter()
{
    Map<String,Integer> map=new HashMap<String,Integer>();
    map.put("图片", R.drawable.a1);
    list.add(map);
    map.put("图片", R.drawable.a2);
    list.add(map);
    map.put("图片", R.drawable.a1);
    list.add(map);
    s=new SimpleAdapter(MainActivity.this,list,R.layout.imageview,new String[]{"图片"},new Integer[]{R.id.image});




}

}

其中，s=new SimpleAdapter.....那行被报错，我截张图：

应该就是说构造方法没这样的重载，明明就应该没错的吧，请问这里是怎么回事？应该怎么解决？

你这样添加有问题，而且你最后那个不能用new Integer[]{},应该用new int[]{}.这样的。

你那个添加有问题。

像下面这样添加，然后把你SimpleAdapter初始化的“图片”改成"image"

 Map<String,Integer> maps1 = new HashMap<String,Integer>();
maps1.put("image",R.drawable.a1);
Map<String,Integer> maps2 = new HashMap<String,Integer>();
maps2.put("image",R.drawable.a2);
Map<String,Integer> maps3 = new HashMap<String,Integer>();
maps3.put("image",R.drawable.a3);
list.add(maps1);
list.add(maps2);
list.add(maps3);
