android - Cant parcel a recycled bitmap 错误

Question

我正在尝试将图像添加到相机表面 View ，并尝试使用以下代码获取该图像。

       else if(v.equals(findViewById(R.id.ok_button))){
//                saveImage();

                topbar.setVisibility(View.GONE);
                menubar.setVisibility(View.GONE);
                bottom.setVisibility(View.GONE);

                View s = ml.getRootView();
                s.setDrawingCacheEnabled(true);

                Bitmap b = s.getDrawingCache();


                Bitmap watermarkimage=b;
                s.setVisibility(View.GONE);
                Log.e("ok","ok");
                Intent i=new Intent(CameraActivity.this,Update.class);
                 i.putExtra("data",watermarkimage);
                 startActivity(i);
                 finish();
                 }

我保存了整个 Activity 以获取图像。通过使用以下代码我获得了位图

 View s = ml.getRootView();
                s.setDrawingCacheEnabled(true);

                Bitmap b = s.getDrawingCache();

当我尝试将此位图发送到另一个 Activity 时出现此错误

Answer 1

尝试制作此位图的副本或克隆并将副本打包。

Bitmap watermarkimage = b.copy(b.getConfig(), true);

我敢猜测 getDrawingCache 返回的数据与 b 和 watermarkimage 共享。所以也许 setVisible 到 Gone 导致它回收。
