Android SoundRecorder (recorder) adds a recording list menu item

Android SoundRecorder (recorder) adds a recording list menu item

Add a recording list item to the recorder. Click it to view the existing recording file.

As follows:

 

 

The code to be modified is as follows:

 

The original recorder does not have the recording list option, so we need to add it.

SoundRecorder esmenumain_menu.xml add recording menu options

 

 

Android: id = @ + id/menu_item_filetype

Android: title = @ string/format_setting/>

Android: id = @ + id/menu_item_storage

Android: title = @ string/storage_setting/>

Android: id = @ + id/menu_item_keyboard

Android: title = @ string/keyboard/>

Android: id = @ + id/menu_item_list

Android: title = @ string/audio_db_playlist_name/>
