KPCompatBasicTextField

@Composable
fun KPCompatBasicTextField(value: String, onValueChange: (String) -> Unit, modifier: Modifier = Modifier, enabled: Boolean = true, readOnly: Boolean = false, textStyle: TextStyle = KPDesign.typography.subtitleMedium, keyboardOptions: KeyboardOptions = KeyboardOptions.Default, keyboardActions: KeyboardActions = KeyboardActions.Default, singleLine: Boolean = false, maxLines: Int = if (singleLine) 1 else Int.MAX_VALUE, visualTransformation: VisualTransformation = VisualTransformation.None, onTextLayout: (TextLayoutResult) -> Unit = {}, interactionSource: MutableInteractionSource = remember { MutableInteractionSource() }, cursorBrush: Brush = SolidColor(KPDesign.colors.colorPrimary), @IdRes viewId: Int = R.id.kp_compat_basic_text_field, decorationBox: @Composable (innerTextField: @Composable () -> Unit) -> Unit = @Composable { innerTextField -> innerTextField() })

Drop-in alternative to Compose androidx.compose.foundation.text.BasicTextField that renders text with a platform android.widget.EditText inside androidx.compose.ui.viewinterop.AndroidView.

Why this exists

Compose Foundation selection / android.view.textclassifier.TextClassifier can crash on some devices (rapid typing + double-tap select-all). See issuetracker.google.com/issues/515272359. This component keeps the familiar BasicTextField API but moves selection to the platform widget.

When to use

Only as a crash workaround. Prefer Foundation androidx.compose.foundation.text.BasicTextField (or Komposto styled inputs) everywhere else — this is not a standard design-system text field.

Migrating from BasicTextField

Most parameters match BasicTextField. Important differences:

  • Apply modifier focus helpers (focusRequester, onFocusChanged, testTag) on this composable. The embedded editor is a focus group — use androidx.compose.ui.focus.FocusState.hasFocus, not isFocused.

  • Width is caller-owned (no forced fillMaxWidth()).

  • keyboardActions: only your lambdas run. Platform defaults (hide IME / focus next) are not forwarded via androidx.compose.foundation.text.KeyboardActionScope.defaultKeyboardAction. Soft-keyboard IME buttons and hardware / emulator Enter both invoke the matching callback. Callbacks are skipped when the host androidx.lifecycle.Lifecycle is below CREATED (Fragment onDestroyView / disposed composition), or when the platform EditText is detached from the window. The editor-action listener is cleared in AndroidView.onRelease.

  • modifier focusRequester / programmatic requestFocus() focuses the platform EditText and shows the IME (same as Foundation BasicTextField). Already-focused requestFocus() (e.g. sibling "X" / clear that calls FocusRequester again) also reshows the IME.

  • textStyle.fontSize is applied as Compose toPx() (COMPLEX_UNIT_PX) so device font scale matches BasicTextField. textStyle.fontFamily is resolved via LocalFontFamilyResolver.

  • visualTransformation is bridged through Android TransformationMethod. Prefer remember { PasswordVisualTransformation() } so the same instance survives recomposition.

  • onTextLayout runs only in preview / inspection (LocalInspectionMode); not on device AndroidView path.

  • cursorBrush: only SolidColor is applied.

  • viewId: Android EditText resource id used by Maestro / UIAutomator id: and by tooling that resolves Resources.getResourceEntryName(view.id). Defaults to R.id.kp_compat_basic_text_field. Pass a caller-owned id (e.g. R.id.editTextSearchView) when the screen needs a unique id. Do not use android.view.View.NO_ID — some app tooling crashes on #0xffffffff.

For caret / selection state, use the TextFieldValue overload.

@Composable
fun KPCompatBasicTextField(value: TextFieldValue, onValueChange: (TextFieldValue) -> Unit, modifier: Modifier = Modifier, enabled: Boolean = true, readOnly: Boolean = false, textStyle: TextStyle = KPDesign.typography.subtitleMedium, keyboardOptions: KeyboardOptions = KeyboardOptions.Default, keyboardActions: KeyboardActions = KeyboardActions.Default, singleLine: Boolean = false, maxLines: Int = if (singleLine) 1 else Int.MAX_VALUE, visualTransformation: VisualTransformation = VisualTransformation.None, onTextLayout: (TextLayoutResult) -> Unit = {}, interactionSource: MutableInteractionSource = remember { MutableInteractionSource() }, cursorBrush: Brush = SolidColor(KPDesign.colors.colorPrimary), @IdRes viewId: Int = R.id.kp_compat_basic_text_field, decorationBox: @Composable (innerTextField: @Composable () -> Unit) -> Unit = @Composable { innerTextField -> innerTextField() })

TextFieldValue overload of KPCompatBasicTextField.

Same purpose and migration notes as the String overload. Additional state caveats:

  • IME composing region (TextFieldValue.composition) is not bridged from EditText.

  • While focused, programmatic selection-only updates are ignored (platform ActionMode owns the caret). Change TextFieldValue.text, or move the cursor via semantics setSelection.

Focus / Unfocus androidx.compose.foundation.interaction.FocusInteractions are emitted on interactionSource from the embedded EditText.
