如何将 Bitmap 对象从一个活动传递到另一个活动
问题描述:
在我的活动中,我创建了一个 Bitmap
对象,然后我需要启动另一个 Activity
,如何从子活动(将要启动的活动)传递这个 Bitmap
对象?
In my activity, I create a Bitmap
object and then I need to launch another Activity
,
How can I pass this Bitmap
object from the sub-activity (the one which is going to be launched)?
答
Bitmap
实现了 Parcelable
,所以你总是可以带着意图传递它:
Bitmap
implements Parcelable
, so you could always pass it with the intent:
Intent intent = new Intent(this, NewActivity.class);
intent.putExtra("BitmapImage", bitmap);
并在另一端检索它:
Intent intent = getIntent();
Bitmap bitmap = (Bitmap) intent.getParcelableExtra("BitmapImage");
