 一、XML代码

1、Activity代码部分
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.administrator.jiugongge.MainActivity">
    <GridView
        android:id="@+id/grid"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="90dp"
        android:gravity="center"
        android:horizontalSpacing="10dp"
        android:verticalSpacing="10dp"
        android:numColumns="3"/>
</RelativeLayout>

 

2、新建LayoutXML代码
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal">
    <LinearLayout
        android:layout_width="80dp"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:orientation="vertical">
        <ImageView
            android:id="@+id/img"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@mipmap/e"/>
        <TextView
            android:id="@+id/txt"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text=""
            android:textColor="#000000"
            android:textSize="15dp"
            android:gravity="center"/>
    </LinearLayout>
</RelativeLayout>

二、JAVA代码及功能实现

package com.example.administrator.jiugongge;
public class MainActivity extends AppCompatActivity {
    private int[] photo = {
            R.mipmap.a,
            R.mipmap.b,
            R.mipmap.c,
            R.mipmap.d,
            R.mipmap.e,
            R.mipmap.f,
            R.mipmap.g,
            R.mipmap.h,
            R.mipmap.p,
   };
    private String[] name = {
            "a",
            "b",
            "c",
            "d",
            "e",
            "f",
            "g",
            "h",
            "p"
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        GridView grid = (GridView) findViewById(R.id.grid);
        int length = photo.length;
        
        
        ArrayList<HashMap<String, Object>> lstImage = new ArrayList<HashMap<String, Object>>();
        for (int i = 0; i < length; i++) {
            HashMap<String, Object> map = new HashMap<String, Object>();
            map.put("Image", photo[i]);
            map.put("Text", name[i]);
            lstImage.add(map);
        }
        SimpleAdapter wangqi = new SimpleAdapter(this,
                lstImage,
                R.layout.layout,
                new String[]{"Image", "Text"},
                new int[]{R.id.img, R.id.txt});
        
        grid.setAdapter(adapter);
        }
}
