isUnfolded

Description​

Returns whether a foldable device is currently unfolded.

It returns true only when getFoldableState() is "unfolded". When the state cannot be determined ("unknown"), it returns false.

Parameters​

None

Returns​

TypeDescription
booltrue if the foldable device is unfolded, false if it is folded or the state is unknown

Notes​

  • This works on foldable Android devices only. On other devices it always returns false.
  • Use the onFoldableStateChanged callback to receive fold state change events.
  • Since "unknown" also returns false, use getFoldableState() when you need a more detailed state.

Example​

// Check whether the device is unfolded
if ($app.isUnfolded()) {
    // Apply a layout suited to the unfolded screen
    $page.setVar("layoutMode", "wide");
} else {
    $page.setVar("layoutMode", "compact");
}

// React in real time to state changes
$vm.onFoldableStateChanged = function(state, isFolded, isUnfolded) {
    if (isUnfolded) {
        console.log("기기가 펼쳐졌습니다.");
    }
};
  • $app.getFoldableState() — returns the current fold state as a string ("folded" / "unfolded" / "unknown")
  • $vm.onFoldableStateChanged(state, isFolded, isUnfolded) — fold state change event
