Description

The MusicPlayer application uses controls such as TProgressBar, and TTrackBar, and platform-specific technologies such as MPMusicPlayerController for iOS, to show how to create a music player.

Your device needs to have at least one song so that you can see the application functionality. The sample allows the audio files listing and standard media controls like play, pause, and volume.

Note: The FireMonkey library contains a TMediaPlayer component that you can use instead of writing your own media player. The FMX.MediaPlayerHD Sample shows how to use TMediaPlayer.

Classes

TFMXMusicPlayerFrm is the form of the application. This class contains objects like: TActionList, TTabControl, TTimer, TSpeedButton, or TTrackBar.

Implementation

• The GetSongsFromLibrary procedure is used to populate PlayListBox with the songs from the library device. It shows the title and the artist of each song.
• The application components are placed on the TabItem1 and TabItem2 pages. You can change between the two pages by setting the ActiveTab property of the TabControl1. Each TabItem of the application has an attached action.
• The SongProgressBar value is calculated in the OnTimer event of TTimer based on the MPMediaItemPropertyPlaybackDuration and currentPlaybackTime methods results.
