android – Displaying ConstraintLayout in a DialogFragment-ThrowExceptions

Exception or error:

I hope you can help me out with a problem. I tried to google it, and looked through the topics here, but was unable to find an answer.

I recently changed my layouts to ConstraintLayouts, and this have been working great so far. My problem however is i had some DialogFragments displaying a LinearLayout, and when i changed it to ConstraintLayout i only shows a faded overlay, but non of the elements in the layout. If i hardcode the width and height to something like 100dp, it will display that area. When i try match_parent or any other combination the same problem applies. I also tried setting the height and width to the device height and width but still with no luck.

In the onCreateView in my CreateWeddingMetadataFragment i have:

createButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d(TAG, "Show message dialog");

            FragmentManager fm = getFragmentManager();
            CreateWeddingMetadataDialogFragment welcomeMessageDialog = new CreateWeddingMetadataDialogFragment();
            welcomeMessageDialog.show(fm, "metadate_fragment_dialog");
            welcomeMessageDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
                @Override
                public void onDismiss(DialogInterface dialog) {
                }
            });

In my CreateWeddingMetadataFragmentDialog i have:

public class CreateWeddingMetadataDialogFragment extends DialogFragment{

private static final String TAG = CreateWeddingMetadataDialogFragment.class.getSimpleName();

public Button setupNow, setupLater;
public TextView mTest;
public ConstraintLayout parentLayout;

private DialogInterface.OnDismissListener onDismissListener;



public void setOnDismissListener(DialogInterface.OnDismissListener onDismissListener) {
    this.onDismissListener = onDismissListener;
}

@Override
public void onDismiss(DialogInterface dialog) {
    super.onDismiss(dialog);
    if (onDismissListener != null) {
        onDismissListener.onDismiss(dialog);
    }
}

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d(TAG, "I was called");
}

public CreateWeddingMetadataDialogFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.create_welcome_message_view, container);

    setupNow = (Button) view.findViewById(R.id.setupNowButton);
    setupLater = (Button) view.findViewById(R.id.setupLaterButton);
    mTest = (TextView) view.findViewById(R.id.welcomeMessageTitle);
    parentLayout = (ConstraintLayout) view.findViewById(R.id.clWelcomeMessage);

    DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
    int width = displayMetrics.widthPixels;
    int height = displayMetrics.heightPixels;

    parentLayout.setMinimumWidth(width);
    parentLayout.setMinimumHeight(height);

    mTest.setText("Test");
    Log.d(TAG, "I was called onCreateView" + mTest);

    setupNow.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //Go to metadate page (Hide this dialog)
        }
    });

    setupLater.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //Go to signin page and create the wedding
        }
    });


    return view;
}

}

That is with my current try of setting it to the device size.

And here is the create_welcome_message_view:

How to solve:

This works fine – check out

1) Its good practice to arrange items in order where possible in XML too as visualized. Just to easily comprehend later.
2) Its looks every other element is constraining itself to others height and width and mostly resulting in 0 height and width. Watch out for 0dp and wrap_content on LayoutParams.
3) Take support of Vertical Bias too.

 </android.support.constraint.ConstraintLayout>

Also, app:layout_constraintWidth_default="wrap" (with width set to 0dp). If set, the widget will have the same size as if using wrap_content, but will be limited by constraints (i.e. it won’t expand beyond them).
