Android之Parcelable使用

必须实现Parcelable：且属性的writeXXX与readXXX必须顺序一一对应。

public class BaseModel implements Parcelable {

    public long mID;

    public long getmID() {
        return mID;
    }

    public void setmID(long mID) {
        this.mID = mID;
    }

    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        // TODO Auto-generated method stub
         dest.writeLong(mID); 
    }

    public static final Parcelable.Creator<BaseModel> CREATOR = new Parcelable.Creator<BaseModel>() {   
        //重写Creator
          
                @Override  
                public BaseModel createFromParcel(Parcel source) {   
                    BaseModel p = new BaseModel();   
                    p.mID = source.readLong(); 
                    return p;   
                }   
          
                @Override  
                public BaseModel[] newArray(int size) {   
                    // TODO Auto-generated method stub   
                    return new BaseModel[size];  
                }   
            };   
          
    
    
}

发送广播：

public static void sendList(Context mContext,ArrayList<MusicModel> list){
        Intent intent = new Intent("PLAYLIST");
        
        intent.putParcelableArrayListExtra(MediaService.MediaServicePlayList, list);
        
        mContext.sendBroadcast(intent);
    }

接收广播：

public class PlayListReceiver extends BroadcastReceiver{

        @Override
        public void onReceive(Context context, Intent intent) {
            
            mList = intent.getParcelableArrayListExtra(MediaServicePlayList);
            
        }
        
    }

注册广播：

playListReceiver = new PlayListReceiver();
        registerReceiver(playListReceiver,new IntentFilter("PLAYLIST"));
