ギャラリー アダプターを介してギャラリー内に画像を表示できます。ここで、各画像の下部にタイトルを追加する必要があります。追加する方法がわかりません。これは私のアダプターコードです:
public class LensaPhotoAdapter_KM extends BaseAdapter{
private int mGalleryItemBackground;
private Context context;
private ImageLoader imageLoader;
// private File cacheDir;
private ImageLoaderConfiguration config;
private DisplayImageOptions options;
private ArrayList<String> imageURLs = new ArrayList<String>();
private ArrayList<String> imageTitle = new ArrayList<String>();
public LensaPhotoAdapter_KM(Context context){
Log.i("LensaPhotoAdapter", "Try to build the screen...");
this.context = context;
TypedArray attr = context.obtainStyledAttributes(R.styleable.HelloGallery);
mGalleryItemBackground = attr.getResourceId(R.styleable.HelloGallery_android_galleryItemBackground, 0);
attr.recycle();
// Get singleton instance of ImageLoader
imageLoader = ImageLoader.getInstance();
}
public void setData(ImageFeedItemList imageFeedItemList){
int numberOfItems = imageFeedItemList.getHeaderImage().size();
imageTitle = imageFeedItemList.getTitle();
// for(String str: imageFeedItemList.getHeaderImage())
// Log.i("title is:", str);
for(int i=0; i<numberOfItems; i++){
String str = imageFeedItemList.getTitle().get(i);
str = str.substring(0, str.indexOf(" "));
if(str.equalsIgnoreCase("Konsert"))
imageURLs.add(imageFeedItemList.getHeaderImage().get(i));
// for(String str1: imageURLs)
// Log.i("title is:", str1);
}
// cacheDir = new File(Environment.getExternalStorageDirectory(), "UniversalImageLoader/Cache");
// Create configuration for ImageLoader
config = new ImageLoaderConfiguration.Builder(context)
.maxImageWidthForMemoryCache(800)
.maxImageHeightForMemoryCache(800)
.httpConnectTimeout(5000)
.httpReadTimeout(30000)
.threadPoolSize(5)
.threadPriority(Thread.MIN_PRIORITY + 2)
.denyCacheImageMultipleSizesInMemory()
.memoryCache(new UsingFreqLimitedMemoryCache(2000000)) // You can pass your own memory cache implementation
// .discCache(new UnlimitedDiscCache(cacheDir)) // You can pass your own disc cache implementation
.defaultDisplayImageOptions(DisplayImageOptions.createSimple())
.build();
// Creates display image options for custom display task
options = new DisplayImageOptions.Builder()
.showStubImage(R.drawable.icon_loading)
.showImageForEmptyUrl(R.drawable.icon_remove)
.cacheInMemory()
.cacheOnDisc()
.decodingType(DecodingType.MEMORY_SAVING)
.build();
// Initialize ImageLoader with created configuration. Do it once.
imageLoader.init(config);
}
//---returns the number of images---
public int getCount() {
return imageURLs.size();
}
//---returns the ID of an item---
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return position;
}
//---returns an ImageView view---
public View getView(int position, View convertView, ViewGroup parent){
ImageView imageView = new ImageView(context);
imageView.setLayoutParams(new Gallery.LayoutParams(250, 250));
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setBackgroundResource(mGalleryItemBackground);
// Load and display image
String imageUrl = imageURLs.get(position);
imageLoader.displayImage(imageUrl, imageView, options);
return imageView;
}
}
任意の提案をいただければ幸いです。ありがとう
