## Inherited Methods

The following methods are inherited from the superclass [`DrawingItem`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md).

| Method | Description |
|------- |-------------|
| [`setDrawingStyleId`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#setdrawingstyleid) | Set the `DrawingStyle` of the `DrawingItem`. If a `DrawingItem` holds a drawing style ID, it will not use the default style of its layer. |
| [`getDrawingStyleId`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#getdrawingstyleid) | Get the DrawingStyle of the `DrawingItem`. |
| [`setState`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#setstate) | Set the state of the `DrawingItem`. |
| [`getState`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#getstate) | Get the state of the `DrawingItem`. |
| [`getCoordinateBase`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#getcoordinatebase) | Get the coordinate base of the `DrawingItem`. The coordinate base is image by default. |
| [`getMediaType`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#getmediatype) | Get the media type of the `DrawingItem`. |
| [`addNote`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#addnote) | Add a note to the `DrawingItem`. |
| [`getNote`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#getnote) | Get the specified `Note`. |
| [`hasNote`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#hasnote) | Check whether the specified Note exists. |
| [`updateNote`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#updatenote) | Update the content of the specified `Note`. |
| [`deleteNote`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#deletenote) | Remove the specified `Note` with the specified name. |
| [`getAllNotes`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#getallnotes) | Get all `Notes` of this DrawingItem. |
| [`clearNotes`](https://www.dynamsoft.com/camera-enhancer/docs/mobile/programming/android/auxiliary-api/drawingitem.md#clearnotes) | Remove all `Notes` of this DrawingItem. |
