[TextInputLayout] OnFocusChangeListener is only notified on first gained focus

[mpost]

Description: Settings a OnFocusChangeListener on the TextInputEditText inside the TextInputLayout notifies the listener only the very first time the focus is gained.

Expected behavior: The listener should always fire when focus is gained and lost.

Source code:

textInputEditText.setOnFocusChangeListener { _, hasFocus -> 
  println("only fires on first focus gained")
}

Android API version: 29

Material Library version: 1.2.0-alpha04

Device: Emulator

Hi, I'm not able to reproduce the issue. Could you provide a sample app?

[mpost]

Ok, closing this issue.

Hi, I have the same issue here. Why this ticket has been closed ? Is there a fix available ? Thanks

[leticiarossi]

@kazougagh can you provide a sample app with the issue since it's not reproducible on our end?

[kazougagh]

Hi @leticiarossi , This issue occurs when you try to set the endIconMode programmatically and not using the xml attributes. Like this:

`

 val inputLayout = findViewById<TextInputLayout>(R.id.text_input_layout)
 inputLayout.editText?.onFocusChangeListener = View.OnFocusChangeListener { _, hasFocus ->

        // ----------------------------
        // Called on first focus only !
        // ----------------------------

        Log.d(TAG, "inputEditText - hasFocus $hasFocus")
        if (inputLayout.endIconMode == TextInputLayout.END_ICON_NONE) {
            inputLayout.endIconMode = TextInputLayout.END_ICON_CLEAR_TEXT
            inputLayout.setEndIconTintList(ColorStateList.valueOf(getColor(R.color.colorPrimaryDark)))
        }
        
    }`

I have the exact same issue, as described by kazougagh. When setting endIconMode programatically its never called again.

Can we reopen this issue since it's still valid and reproducible example was provided by kazougagh?

Also this is relevant to comment in different issue https://github.com/material-components/material-components-android/issues/503#issuecomment-757379005

Both ClearTextEndIconDelegate and DropdownMenuEndIconDelegate set their own OnFocusChangeListener which replaces any OnFocusChangeListener that was previously set on the EditText.

I have the same issue with this code. While debugging, the breakpoint only stopped once.

edtStreet.onFocusChangeListener =
            View.OnFocusChangeListener { _, hasFocus ->
                if (!hasFocus && !isValidField(edtStreet.text)) {
                    binding.edlStreet.setEndIconDrawable(R.drawable.ic_error_white)
                    binding.edlStreet.setEndIconOnClickListener { showToast() }
                    binding.edlStreet.endIconMode = END_ICON_CUSTOM
                    binding.edlStreet.isEndIconVisible = true
                } else {
                    binding.edlStreet.setEndIconDrawable(R.drawable.ic_clear_white)
                    binding.edlStreet.endIconMode = END_ICON_CLEAR_TEXT
                    binding.edlStreet.isEndIconVisible = true
                }
            }

FWIW, I just thought I'd encountered a similar problem, when I really didn't understand how hasFocus worked.

Your current view will not lose focus unless something else if focused. This means that your parent view, or something else in your layout, should have android:focusableInTouchMode="true". That way, the edittext will actually lose focus when you click outside of the EditText, and your listener should fire just fine.

I meet the same problem :(

I have the same problem. Any plans here?
