根据可用图片的数量，我使用imageview或图库。当只有一张图片可用时，它使用imageview并且像魅力一样工作。我使用u niversalloader的图像加载器。照片全宽在我的屏幕上方。图库图片应填充屏幕宽度
当有多个图片我使用一个画廊，与pagerindicators。在较小的屏幕上，这工作正常。但是在平板电脑上，图片并没有填满整个屏幕，这很奇怪，因为单一的图像查看功能，图像加载程序的工作完美。我认为这与我的画廊设置有关。为画廊
代码：
// define pager identifier
pager = (LinearLayout)findViewById(R.id.pager);
pagerdot1 =(ImageView)pager.findViewById(R.id.pager_dot_1);
pagerdot2 =(ImageView)pager.findViewById(R.id.pager_dot_2);
pagerdot3 =(ImageView)pager.findViewById(R.id.pager_dot_3);
venueImage = (ImageView)findViewById(R.id.venueImage);
venueGallery = (CustomGallery)findViewById(R.id.GVvenueImage);
imageLoader=new LargerImageLoader(this.getApplicationContext());
if(venue.photos.size()>1){//multiple photos --> gallery
if(venue.photos.size()==2){
pagerdot3.setVisibility(View.GONE);
}
venueGallery.setVisibility(View.VISIBLE);
venueImage.setVisibility(View.GONE);
String[] fotos = new String[venue.photos.size()];
for(int i=0;i<venue.photos.size();i++){
if(venue.photos.get(i).large !=null){
fotos[i] = venue.photos.get(i).large;
System.out.println(venue.photos.get(i).large);
}
}
ImagePagerAdapter galleryad = new ImagePagerAdapter(fotos);
venueGallery.setAdapter(galleryad);
venueGallery.setOnItemSelectedListener(new OnItemSelectedListener(){
@Override
public void onItemSelected(AdapterView<?> adapter, View view, int position, long id) {
switch(position) {
case 0:
pagerdot1.setImageResource(R.drawable.pager_oranje);
pagerdot2.setImageResource(R.drawable.pager_wit);
pagerdot3.setImageResource(R.drawable.pager_wit);
break;
case 1:
pagerdot2.setImageResource(R.drawable.pager_oranje);
pagerdot1.setImageResource(R.drawable.pager_wit);
pagerdot3.setImageResource(R.drawable.pager_wit);
break;
case 2:
pagerdot3.setImageResource(R.drawable.pager_oranje);
pagerdot2.setImageResource(R.drawable.pager_wit);
pagerdot1.setImageResource(R.drawable.pager_wit);
break;
default:
pagerdot1.setImageResource(R.drawable.pager_oranje);
pagerdot2.setImageResource(R.drawable.pager_wit);
pagerdot3.setImageResource(R.drawable.pager_wit);
}
}
@Override
public void onNothingSelected(AdapterView<?> adapter) {
}
});
}else if(venue.photos.size() ==1){ //1 foto
if(venue.photos.get(0).large != null){
venueGallery.setVisibility(View.GONE);
venueImage.setVisibility(View.VISIBLE);
imageLoader.DisplayImage(venue.photos.get(0).large, venueImage);
} else{
setStandardPic();
}
pager.setVisibility(View.GONE);
//
} else{
setStandardPic();
}
，并用：
private class ImagePagerAdapter extends BaseAdapter {
private String[] images;
private LayoutInflater inflater;
ImagePagerAdapter(String[] images) {
this.images = images;
inflater = getLayoutInflater();
}
@Override
public int getCount() {
return images.length;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = null;
RelativeLayout borderImg;
if (convertView == null) {
imageView = new ImageView(getBaseContext());
imageView.setLayoutParams(new LayoutParams(width,height)); // size
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setPadding(0,0,0,0);
imageView = (ImageView) inflater.inflate(R.layout.item_gallery_image, parent, false);
borderImg = new RelativeLayout(getBaseContext());
borderImg.setPadding(0,0,0,0);
borderImg.setBackgroundColor(Color.TRANSPARENT); // no color
}else {
imageView = (ImageView) convertView;
borderImg = (RelativeLayout) convertView;
}
imageLoader.DisplayImage(images[position], imageView);
borderImg.addView(imageView);
return borderImg;
}
}

我的定制库只是一个普通的画廊与onFling方法覆盖更好的投掷设置。
我应该更改哪些内容才能使我的画廊在平板电脑屏幕上也能正常工作？
