10## APIs
11
12LongPressGesture(value?: { fingers?: number, repeat?: boolean, duration?: number })
13
14Triggers a long press gesture. In components that support drag actions by default, such as **Text**, **TextInput**, **TextArea**, **HyperLink**, **Image**, and **RichEditor**, the long press gesture may conflict with the drag action. If this occurs, they are handled as follows:
15
16If the minimum duration of the long press gesture is less than 500 ms, the long press gesture receives a higher response priority than the drag action.
17
18If the minimum duration of the long press gesture is greater than or equal to 500 ms, the drag action receives a higher response priority than the long press gesture.

50// xxx.ets
51@Entry
52@Component
53struct LongPressGestureExample {
54  @State count: number = 0
55
56  build() {
57    Column() {
58      Text('LongPress onAction:' + this.count).fontSize(28)
59        // Touch and hold the text with one finger to trigger the gesture event.
60        .gesture(
61        LongPressGesture({ repeat: true })
62          // When repeat is set to true, the event callback is triggered continuously when the gesture is detected. The triggering interval is specified by duration (500 ms by default).
63          .onAction((event: GestureEvent) => {
64            if (event && event.repeat) {
65              this.count++
66            }
67          })
68            // Triggered when the long press gesture ends.
69          .onActionEnd((event: GestureEvent) => {
70            this.count = 0
