Serializable(接口)
通过intent 的bundle传递参数
Bundle bundle = new Bundle();
bundle.putSerializable(IntentKeys.IMG_ARR_ENVIR_IMG, mArrListEnvir_img);
intent.putExtras(bundle);
mListEnvir = (ArrayList<EnvirImg>) (bundle
.getSerializable(IntentKeys.IMG_ARR_ENVIR_IMG));
Parcelable(接口)
通过intent 的bundle传递参数
Bundle bundle = new Bundle();
bundle.putParcelable(IntentKeys.IMG_ARR_ENVIR_IMG, mArrListEnvir_img);
intent.putExtras(bundle);
import android.graphics.Bitmap;
import android.os.Parcel;
import android.os.Parcelable;
public class UploadPic implements Parcelable{
private String id;
private String sdPath;
private String webPath;
private Bitmap bmp;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getSdPath() {
return sdPath;
}
public void setSdPath(String sdPath) {
this.sdPath = sdPath;
}
public String getWebPath() {
return webPath;
}
public void setWebPath(String webPath) {
this.webPath = webPath;
}
public Bitmap getBmp() {
return bmp;
}
public void setBmp(Bitmap bmp) {
this.bmp = bmp;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel parcel, int flags) {
parcel.writeString(id);
parcel.writeString(sdPath);
parcel.writeString(webPath);
bmp.writeToParcel(parcel, 0);
}
public static final Parcelable.Creator<UploadPic> CREATOR = new Creator<UploadPic>() {
public UploadPic createFromParcel(Parcel source) {
UploadPic pic = new UploadPic();
pic.id = source.readString();
pic.sdPath = source.readString();
pic.webPath = source.readString(); //传递string数据
pic.bmp = Bitmap.CREATOR.createFromParcel(source);//传递bitmap数据
return pic;
}
public UploadPic[] newArray(int size) {
return new UploadPic[size];
}
};
}
Parcelable比Serializable效率高
parcelable也不适合传输大量图片数据
android.os.TransactionTooLargeException 不适合传大量数据尤其bitmap intent跳转的时候无缝传递数据pacicl
导致原因是:Binder传输的数据太大
如果Binder的参数或返回值太大,不适合的事务缓冲区,然后调用将失败,并将被抛出TransactionTooLargeException。
解决方法:
不要将大量数据传入Binder
