Focus Changes on TextField without any text changes triggers `onValueChanged` callback [178510628]

created issue #1

Jan 27, 2021 04:26PM

Click on TextField, lose focus and click again or put app in background and reopen, these focus changes calls the onValueChange callback of TextField even with no actual text changes. This is unexpected behaviour and onValueChange callback should only be called when there's any actual change in the text.

Here's a repro for you ImeGlitch. I've used this sample to report another issue but have added a simple log indicating OnValueChanged called unnecessarily

Prevent TextField.onValueChange to fire if no change

- Added TextFieldValue overload to compare previous and
new value
- Replaced string version calling into TextFieldValue
version in order to
a) prevent double string comparison
b) (minor) extra function call

Test: ./gradlew compose:foundation:foundation:test

Add tests for BasicTextField.onValueChange

Added tests to check when
- no change occurs in text, String overload does not
call onValueChange
- no change occurs in value, TextFieldValue overload
does not call onValueChange

Hi, look like a part of this bug still remains. When the CoreTextField composable is disposed, onBlur gets called inside TextFieldDelegate. A copy of TextFieldValue object is created there editProcessor.toTextFieldValue().copy(composition = null) When this happens onValueChanged will always get called since it will fail the if check

if (value != it) {
 onValueChange(it)
}

I am seeing this on foundation:1.5.0-alpha01. Please fix thanks!

The status is shown as 'Fixed'. I wonder if it is being looked into. If so, please help us tracking it.

I am facing issue where recomposition happens and the state is reset due to onValueChange() that is causing unnecessary and wrongful recomposition.
