无法打包回收的位图错误

Question

我正在尝试将图像添加到相机表面视图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();
                 }

我保存了整个活动以获取图像。通过使用以下代码，我得到了位图

 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活动时，我收到此错误

Answer 1

尝试制作此位图的副本或克隆并打包副本。

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

我会冒险猜测 getDrawingCache 返回的数据与 b 和 watermarkimage 共享。所以也许 setVisible to Gone 会导致它被回收。
