Answer 1

you need to put those steps to make it work perfectly

1-in your xml put this

you just need to set android:completionThreshold to zero

2- in your java code put

  mViewDataBinding.accountTypeSpinner.setOnFocusChangeListener((v, hasFocus) -> {
        if (hasFocus)
            mViewDataBinding.accountTypeSpinner.showDropDown();
    });
