我不知道为什么会这样，我无法重现它。 它在控制台中。
我真的很抱歉只是输入代码和日志猫但我甚至无法读取logcat，我之前没有遇到过这样的问题，我甚至不知道从哪里开始。 任何帮助将不胜感激。
这是日志猫，

这是类的代码
public class SongDetails implements Parcelable
{
public SongDetails( int _ID, String click_no, String Album, String Artist, String Path, String Time, String song, String sortBy, int albumID,
String audioID )
{
this._ID = _ID;
this.click_no = click_no;
this.Album = Album;
this.Artist = Artist;
this.Path = Path;
this.Time = Time;
this.song = song;
this.sortBy = sortBy;
this.albumID = albumID;
this.audioID = audioID;
}
public SongDetails( Parcel in )
{
this._ID = in.readInt( );
this.Path = in.readString();
this.song = in.readString( );
this.Album = in.readString( );
this.Artist = in.readString( );
this.Time = in.readString( );
this.sortBy = in.readString( );
this.click_no = in.readString( );
this.albumID = Integer.parseInt( in.readString( ) );
this.audioID = in.readString( );
}
@Override
public int describeContents( )
{
return 0;
}
@Override
public void writeToParcel( Parcel dest, int flags )
{
dest.writeInt( _ID );
dest.writeString( Path );
dest.writeString( song );
dest.writeString( Album );
dest.writeString( Artist );
dest.writeString( Time );
dest.writeString( sortBy );
dest.writeString( click_no );
dest.writeString( String.valueOf( albumID ) );
dest.writeString( audioID );
}
public static final Parcelable.Creator < SongDetails > CREATOR = new Parcelable.Creator < SongDetails >( ) {
public SongDetails createFromParcel( Parcel in )
{
return new SongDetails( in );
}
public SongDetails [ ] newArray( int size )
{
return new SongDetails [ size ];
}
};
}
活动代码，其中正在读取可分割数据
Bundle bundle = getIntent( ).getExtras( );
if ( bundle != null )
{
if ( GlobalSongList.GetInstance( ).getCheck( ) == 0 )
{
try
{
GlobalSongList.GetInstance( ).setPosition( bundle.getInt( "Data2", 0 ) );
if(bundle.getParcelableArrayList( "Data1" )!=null)
{
ArrayList < SongDetails > list =
bundle.getParcelableArrayList( "Data1" );
GlobalSongList.GetInstance( ).SetNowPlayingList( list );
}
CMDNAME = bundle.getString( IConstant.CMDNAME );
}
catch ( Exception e )
{
// e.printStackTrace( );
}
}
comefrom = bundle.getString( "comefrom" );
isFromRecentAdded = bundle.getBoolean( "fromRecentAdded", false );
click_no = bundle.getString( "click_no_playlist" );
答案 0 :(得分：4)
我认为问题在于您在解组SongDetails列表时没有设置类加载器。
您可以执行以下操作来阅读"Data1"：
if(bundle.getParcelableArrayList( "Data1" )!=null) {
bundle.setClassLoader (SongDetails.class.getClassLoader());
ArrayList < SongDetails > list = bundle.getParcelableArrayList( "Data1" );
// Rest of your code
}
