EditText inside TextInputLayout onclick requires 2 click ?! Android

Question

I am simply trying to have an onlick listen on an Edit text inside a TextInputLayout. It works but I need to click on the EditText twice for it to trigger I dont understand why.

Answer 1

Set the attribute android:focusableInTouchMode to false

android:focusableInTouchMode="false"

in your edittext xml code.

Explanation, as from docs, android:focusableInTouchMode is:

Boolean that controls whether a view can take focus while in touch mode. If this is true for a view, that view can gain focus when clicked on, and can keep focus if another view is clicked on that doesn't have this attribute set to true.

and the EditText is true by default.

In other words: the first click will make the edittext to gain focus and second click is the one that triggers the ClickListener. So you should disable gaining focus on touch.

Answer 2

I found an alternative solution which suited my needs better than the other answer. Basically you set the onClickListener as normal, but you add an OnFocusChangedListener to pick up the first tap (when gaining focus). This only activates in touch mode so doesn't affect keyboard navigation.

You don't need to set any XML attributes related to focus, just use the following code (it's kotlin btw):

    editText.setOnFocusChangeListener { view, isFocused ->
        if (view.isInTouchMode && isFocused) {
            view.performClick()  // picks up first tap
        }
    }
    editText.setOnClickListener {
        showDatePicker() // the actual thing you want to do
    }

This method has the advantage that the view will remain focused (and if you are using a TextInputLayout.OutlinedBox style, it will remain highlighted) even after the DatePicker is dismissed. This does not happen when you set focusableInTouchMode = false.

Once the view is focused, future taps will trigger only the OnClickListener, so it won't be called again by the FocusChangeListener calling performClick(). (I checked this with the debugger on API 29)
