我有一些使用轮播效果显示的图像:
这是代码:
** carousel_main.xml **
<com.digitalaria.gama.carousel.Carousel
android:id="@+id/carousel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"/>
</LinearLayout>
** carousel_item.xml **
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/itemImage"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
.java文件:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.carousel_main);
init();
}
private void init() {
// create the carousel object.
carousel = (Carousel) findViewById(R.id.carousel);
// configurations for the carousel.
carousel.setType(Carousel.TYPE_COVERFLOW);
carousel.setOverScrollBounceEnabled(true);
carousel.setInfiniteScrollEnabled(false);
carousel.setItemRearrangeEnabled(true);
// set images for the carousel.
adapter = new ImageAdapter(this);
carousel.setAdapter(adapter);
// change the first selected position.
carousel.setCenterPosition(3);
}
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
@Override
public int getCount() {
return musicCover.length;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return musicCover[position];
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
view = LayoutInflater.from(mContext).inflate(R.layout.carousel_item, parent, false);
view.setLayoutParams(new Carousel.LayoutParams(450, 450));
ViewHolder holder = new ViewHolder();
holder.imageView = (ImageView) view.findViewById(R.id.itemImage);
view.setTag(holder);
}
ViewHolder holder = (ViewHolder) view.getTag();
holder.imageView.setImageResource(musicCover[position]);
return view;
}
private class ViewHolder {
ImageView imageView;
}
}
在图像中,您可以看到左侧、中间和右侧(黑色空间)之间有很多空间。
发生的事情是,如果我将大小view.setLayoutParams(new Carousel.LayoutParams(450, 450));
增加到 600,600,那么左右项目将不可见。
如何解决这个问题?
