android 画廊进入网格样式菜单

大家好，请帮我解决有关 android 中的菜单的问题。我想将此画廊作为我的应用程序的网格菜单。请指导我如何将名称放在图像下方，如果我单击特定图像，则应打开新活动，最后单击菜单按钮将我带回主屏幕

here is the image

这是代码

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class DisplayViewsExample extends Activity
{    
    //---the images to display---
    Integer[] imageIDs = {
            R.drawable.pic1,
            R.drawable.pic2,
            R.drawable.pic3,
            R.drawable.pic4,
            R.drawable.pic5,
            R.drawable.pic6,
            R.drawable.pic7                    
    };

    @Override    
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.displayview);

        GridView gridView = (GridView) findViewById(R.id.gridview);
        gridView.setAdapter(new ImageAdapter(this));

        gridView.setOnItemClickListener(new OnItemClickListener() 
        {
            public void onItemClick(AdapterView parent, 
            View v, int position, long id) 
            {                
                Toast.makeText(getBaseContext(), 
                        "pic" + (position + 1) + " selected", 
                        Toast.LENGTH_SHORT).show();
            }
        });        
    }

    public class ImageAdapter extends BaseAdapter 
    {
        private Context context;

        public ImageAdapter(Context c) 
        {
            context = c;
        }

        //---returns the number of images---
        public int getCount() {
            return imageIDs.length;
        }

        //---returns the ID of an item--- 
        public Object getItem(int position) {
            return position;
        }

        public long getItemId(int position) {
            return position;
        }

        //---returns an ImageView view---
        public View getView(int position, View convertView, ViewGroup parent) 
        {
            ImageView imageView;
            if (convertView == null) {
                imageView = new ImageView(context);
                imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
                imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
                imageView.setPadding(5, 5, 5, 5);
            } else {
                imageView = (ImageView) convertView;
            }
            imageView.setImageResource(imageIDs[position]);
            return imageView;
        }
    }    
}

这是 XML

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/gridview"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:numColumns="auto_fit"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:columnWidth="90dp"
    android:stretchMode="columnWidth"
    android:gravity="center"
/>

您需要使用自定义适配器而不是ImageAdapter，并添加一个垂直LinearLayout与图像和标签。查看BaseAdapter api: http://developer.android.com/reference/android/widget/BaseAdapter.html

对于点击事件，使用OnItemClickAdapter: http://developer.android.com/reference/android/widget/AdapterView.OnItemClickListener.html
