使用示例

• 基础用法

XComponent({
  id: 'player',
  type: XComponentType.SURFACE,
  libraryname: 'hmvideoplayer',
  controller: this.xComponentController
})
  .onLoad(() => {
    this.xComponentController.setXComponentSurfaceRect({ surfaceWidth: WIDTH_PX, surfaceHeight: HEIGHT_PX });
    HmVideoPlayer.initWithURL(this.URL);
  })
  .width('100%')
  .height('100%')


onPageShow():void {
  this.setVideoPlayerCallback();
}
