Android圖庫到網格樣式菜單

Question

大家好，請幫助我關於Android的菜單。我想讓這個畫廊成爲我的應用程序的網格菜單。請指導我如何，我可以把這個名字的圖片下，如果在特定的圖像新的活動應該打開，並在菜單上的按鈕，最後點擊I單擊帶我回到主屏幕

這裏是圖像

下面是代碼

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; 
     } 
    }  
} 

這裏是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" 
/>

您需要使用自定義適配器而不是ImageAdapter，並添加垂直LinearLayout與圖像和標籤。退房BaseAdapter API：http://developer.android.com/reference/android/widget/BaseAdapter.html

對於點擊事件，使用OnItemClickAdapter：http://developer.android.com/reference/android/widget/AdapterView.OnItemClickListener.html
