在网格视图中添加带有链接的按钮android

Question

我写了一个网格视图代码，它在网格视图中显示图像。在这里，我的问题是与网格视图下的链接添加一个按钮（如果用户点击了按钮，那么它应该导航到相应的链接）

这里是我的Java代码：

 public class some_class extends ActionBarActivity { 
     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
      setContentView(R.layout.gridview); 
     GridView gridview = (GridView) findViewById(R.id.gridview); 
     gridview.setAdapter(new ImageAdapter(this)); 
       } 
     public class ImageAdapter extends BaseAdapter{ 
      private Context mContext; 
      public int getCount() { 
     return mThumbIds.length; 
      } 
       public Object getItem(int position) { 
       return mThumbIds[position]; 
       } 
       public long getItemId(int position) { 
       return 0; 
       } 
       public ImageAdapter(Context c) { 
      mContext = c; 
      } 

      public View getView(int position, View convertView, ViewGroup parent) { 
       ImageView imageView; 
      if (convertView == null){ 
       imageView = new ImageView(mContext); 
        imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); 
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
        imageView.setPadding(8, 8, 8, 8); 
        } 
          else{ 
        imageView = (ImageView) convertView; 
        } 
         imageView.setImageResource(mThumbIds[position]); 
        return imageView; 
         } 

         private Integer[] mThumbIds = { 
            R.drawable.minee1, 
         R.drawable.minee2, R.drawable.minee3, 
        R.drawable.minee4, R.drawable.minee5, 
          R.drawable.minee6, R.drawable.minee7, 
        R.drawable.minee8, R.drawable.minee9, 
          R.drawable.minee10, R.drawable.minee11, 


       }; 

       } 



        @Override 
        public boolean onCreateOptionsMenu(Menu menu) { 

        getMenuInflater().inflate(R.menu.bagavan_pics, menu); 
       return true; 
      } 

       @Override 
       public boolean onOptionsItemSelected(MenuItem item) { 
       // Handle action bar item clicks here. The action bar will 
       // automatically handle clicks on the Home/Up button, so long 
       // as you specify a parent activity in AndroidManifest.xml. 
       int id = item.getItemId(); 
       if (id == R.id.action_settings) { 
      return true; 
       } 
      return super.onOptionsItemSelected(item); 
       } 
       }

在Java代码：

findViewById(R.id.button1).setOnClickListener(new OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        String url = "your url here"; 

        Intent i = new Intent(Intent.ACTION_VIEW); 
        i.setData(Uri.parse(url)); 
        startActivity(i); 
       } 
      }); 

XML代码：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:gravity="center" 
    android:orientation="vertical" > 

    <GridView 
     android:id="@+id/gridView1" 
     android:layout_width="fill_parent" 
     android:layout_height="0dip" 
     android:layout_weight="1" 
     android:clipChildren="true" 
     android:columnWidth="100dp" 
     android:gravity="center" 
     android:numColumns="auto_fit" 
     android:scrollbars="none" 
     android:stretchMode="columnWidth" > 
    </GridView> 

    <LinearLayout 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:gravity="center" 
     android:paddingBottom="5dp" 
     android:paddingLeft="9dp" 
     android:paddingRight="9dp" 
     android:paddingTop="5dp" > 

     <Button 
      android:id="@+id/button1" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:layout_gravity="bottom|center" 
      android:gravity="center" 
      > 
     </Button> 
    </LinearLayout> 

</LinearLayout>
