Android 검색어 : 격자 표시 (이미지)

Question

한 줄에 2 개의 이미지를 격자 형식으로 표시하고 싶습니다. Android Query에서 어떻게합니까? 기존로서는 ... 충분하고 적절한 문서 부족

activity_identify_animals.xml :

<ProgressBar     
    android:layout_width="15dip"  
    android:layout_height="15dip" 
    android:id="@+id/progress" 
    android:layout_centerInParent="true" 
    /> 

<ImageView 
    android:id="@+id/image"  
    android:layout_width="fill_parent"

Answer 1

당신은 2 열

<GridView 
    android:id="@+id/gridviewimg" 
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent" 
    android:gravity="center" 
    android:numColumns="2" 
    android:scrollbarStyle="outsideInset" 
    android:smoothScrollbar="true" 
    android:verticalSpacing="10dp" 
    android:paddingBottom="50dp" 
    android:paddingTop="10dp" /> 

편집 물론 함께있는 gridview를 사용할 수 있습니다. 당신은 당신의 자신의 어댑터 클래스를 작성하고

public class ImageListAdapter extends BaseAdapter { 

private Context context; 
private List<String> imgPic; 

public ImageListAdapter(Context c, List<String> thePic) { 
    context = c; 
    imgPic = thePic; 
} 

public int getCount() { 
    if(imgPic != null) 
     return imgPic.size(); 
    else 
     return 0; 
} 

//---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; 
    BitmapFactory.Options bfOptions=new BitmapFactory.Options(); 
    bfOptions.inDither=false;      //Disable Dithering mode 
    bfOptions.inPurgeable=true;     //Tell to gc that whether it needs free memory, the Bitmap can be cleared 
    bfOptions.inInputShareable=true;    //Which kind of reference will be used to recover the Bitmap data after being clear, when it will be used in the future 
    bfOptions.inTempStorage=new byte[32 * 1024]; 
    if (convertView == null) { 
     imageView = new ImageView(context); 
     imageView.setLayoutParams(new GridView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT)); 
     imageView.setPadding(0, 0, 0, 0); 
    } else { 
     imageView = (ImageView) convertView; 
    } 
    FileInputStream fs = null; 
    Bitmap bm; 
    try { 
     fs = new FileInputStream(new File(imgPic.get(position).toString())); 

     if(fs!=null) { 
      bm=BitmapFactory.decodeFileDescriptor(fs.getFD(), null, bfOptions); 
      imageView.setImageBitmap(bm); 
      imageView.setId(position); 
      imageView.setLayoutParams(new GridView.LayoutParams(200, 160)); 
     } 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } finally{ 
     if(fs!=null) { 
      try { 
       fs.close(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
    } 
    return imageView; 
} 

}
