Parse M3U music link file and m3u Link

Parse M3U music link file and m3u Link

M3U is essentially not an audio file. It is a list file of audio files and a plain text file. You can download it and open it. The playback software does not play it, but finds the network address based on its records for online playback.

Next we will parse the music network address in the m3u File:

1. The interface is as follows: the interface is very simple. An input box (enter a m3u File Link), and then the resolution, start, and end buttons. After resolution is complete, start button to get focus

Play the music parsed from the m3u File

II. the xml file is as follows:

<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/tools" android: layout_width = "match_parent" android: layout_height = "match_parent" android: paddingBottom = "@ dimen/activity_vertical_margin" android: paddingLeft = "@ dimen/plugin" android: paddingRight = "@ dimen/plugin" android: paddingTop = "@ dimen/activity_v Ertical_margin "tools: context = ". mainActivity "> <EditText android: layout_width =" fill_parent "android: layout_height =" wrap_content "android: id =" @ + id/m3uTextPath "/> <LinearLayout android: layout_width = "fill_parent" android: layout_height = "wrap_content" android: orientation = "horizontal" android: layout_marginTop = "60dip"> <Button android: layout_width = "wrap_content" android: layout_height = "wrap_content" Droid: id = "@ + id/parse" android: onClick = "mainCLick" android: text = "resolution"/> <Button android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: id = "@ + id/start" android: onClick = "mainCLick" android: text = "start"/> <Button android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: id = "@ + id/stop" android: onClick = "mainCLick" android: text = "Terminate"/> <Button android: layout _ Width = "wrap_content" android: layout_height = "wrap_content" android: id = "@ + id/pausePull" android: onClick = "mainCLick" android: text = "pull Parsing"/> </LinearLayout> <! -- ListView with id @ id/android: list is a custom list layout. If no, the system calls the default layout --> <ListView android: id = "@ id/android: list" android: layout_width = "fill_parent" android: layout_height = "wrap_content" android: background = "#00FF00" android: drawselectid Top = "false" android: layout_marginTop = "100dip"/> <! -- If the ListView contains no data, the view with the id @ id/android: empty is displayed. --> <TextView android: id = "@ id/android: empty" android: layout_width = "fill_parent" android: layout_height = "wrap_content" android: textColor = "# FF0000" android: text = "No data" android: gravity = "center_vertical | center_horizontal" android: layout_marginTop = "110dip"/> </RelativeLayout>
