mlayout | Portable layout engine in C

Not sure whats wrong with your code. i have created a sample, just try the code below it working fine. make sure to add android:visibility="gone" for panel view in layout so that its hidden at first launch.

QCamera::FrontFace and QCamera::BackFace are just positions of the camera. To achieve what you want, you should flip every image.

Create QCameraImageCapture and connect to its imageCaptured() signal.

Your problem lies in the absence of a move assignment operator. Looking at your class, you have defaulted this operation.

Unfortunately, = default means that you get the default behavior, not that this method is created. This is really confusing.

To make this easier to spot I've recently enabled the following clang warning as error on the code base I'm working on: https://clang.llvm.org/docs/DiagnosticsReference.html#wdefaulted-function-deleted (Maybe GCC has something similar)

Long story short, if you have a base class or member that doesn't allow this operation, your class can't default this.

In this case, you have a reference as a member, as one can't reassign a reference, one can't provide the assignment operator.

Possible workarounds are: store as a raw pointer, or store as std:: reference_wrapper.

PS: please make your deleted methods public and use = delete, it will give much better error messages

You can do that by get the text :-

You should check if the value that is arriving in the second activity is different from null before using it. Try to do something like this and put a breakpoint to debug what's coming up in your second activity:

1st Activity:

To answer my own question: It finally turned out to be a layout problem. What I hadn't considered was that my Fragment within which my ListView gets created within a ScrollView (which was not part of the layout xml that I posted in my question. Within that ScrollView a list of choices (links to various settings) gets replaced by my Fragment containing the ListView. However, the original ScrollView doesn't necessarily fill the full height of the screen, so I just needed to set an attribute android:fillViewport to the ScrollView's XML and set it to true. That allowed the ListView to stretch to the bottom of the screen and the items, of which I first thought they weren't considered by my adapter, suddenly became visible.

Here's the simplified source of the parent ScrollView (within a FrameLayout)

I think you got an error like that "java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first."

• Step 1:

  mConstraintLayout.addView(et,0);

• Step 2:

  return et;

• Step 3:

  mLayout.addView(createNewEditText(mEditText.getText().toString()));

How to fix it:

• Change logic add et view (in method createNewEditText / outside it)

Example:

Check this answer for setting margin in general view. But if the EditText is inside ConstraintLayout you have to have constraint on the EditText for the side which you want to add margin. For example, if you want to add margin to the end of the view, you have to set layout_constraintEnd_toEndOf or layout_constraintEnd_toStartOf in the EditText. Check this answer for adding constraint programatically.

You need to put your POJOs (model classes) in a single package and add that package to your proguard rules, or you can add all of the packages where those classes are (I just personally use a single package for them). Firebase uses reflection in serialization and deserialization process so it can't use obfuscated class names. Once you've put all of them in one package add this rule to your proguard file to prevent obfuscation:
