我正在使用导航抽屉从picasa web api获取相册列表。我一直在尝试实现与标签项相同的列表。有人可以帮我实施吗？
这是导航抽屉项目类，用于显示导航抽屉中的相册。
public class NavDrawerItem {
private String albumId, albumTitle;
// boolean flag to check for recent album
private boolean isRecentAlbum = false;
public NavDrawerItem() {
}
public NavDrawerItem(String albumId, String albumTitle) {
this.albumId = albumId;
this.albumTitle = albumTitle;
}
public NavDrawerItem(String albumId, String albumTitle,
boolean isRecentAlbum) {
this.albumTitle = albumTitle;
this.isRecentAlbum = isRecentAlbum;
}
public String getAlbumId() {
return albumId;
}
public void setAlbumId(String albumId) {
this.albumId = albumId;
}
public String getTitle() {
return this.albumTitle;
}
public void setTitle(String title) {
this.albumTitle = title;
}
public boolean isRecentAlbum() {
return isRecentAlbum;
}
public void setRecentAlbum(boolean isRecentAlbum) {
this.isRecentAlbum = isRecentAlbum;
}
}
