@Override
public Drawable getDrawable(final InputStream aFileInputStream) {
try {
// default implementation will load the file as a bitmap and create
// a BitmapDrawable from it
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
BitmapPool.getInstance().applyReusableOptions(bitmapOptions);
final Bitmap bitmap = BitmapFactory.decodeStream(aFileInputStream, null, bitmapOptions);
if (bitmap != null) {
return new ReusableBitmapDrawable(bitmap);
}
} catch (final OutOfMemoryError e) {
// logger.error("OutOfMemoryError loading bitmap");
System.gc();
// throw new LowMemoryException(e);
}
return null;

示例3: getTileBitmap
import org.osmdroid.tileprovider.BitmapPool; //导入依赖的package包/类
/**
* Try to get a tile bitmap from the pool, otherwise allocate a new one
*
* @param pTileSizePx
* @return

}

}
示例4: tileLoaded
import org.osmdroid.tileprovider.BitmapPool; //导入依赖的package包/类
@Override
protected void tileLoaded(final MapTileRequestState pState, final Drawable pDrawable) {
removeTileFromQueues(pState.getMapTile());
// don't return the tile because we'll wait for the fs provider to ask for it
// this prevent flickering when a load of delayed downloads complete for tiles
// that we might not even be interested in any more

// We want to return the Bitmap to the BitmapPool if applicable
if (pDrawable instanceof ReusableBitmapDrawable)
