Question

我正在尝试将图像添加到相机surfaceview，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

尝试复制或克隆此位图并将副本包裹起来。

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

我猜测getDrawingCache返回的数据与b和watermarkimage共享。所以也许setVisible to Gone会导致它回收。

无法包裹回收位图错误
