        try {
            shareIntent = Intent.parseUri(sendText,
                    Intent.URI_INTENT_SCHEME);

}

CodePudding user response：

now I can see my file song But the name shown in the app is the file address instead

I think you are referring to the "Path" of the file, for example:

/storage/emulated/0/song.mp3 (Unix style path)

C:\Songs\song.mp3 (Window style path)

If you would like to parse (find out) the name of the file, use the following code:

String filePath = "/storage/emulated/0/song.mp3";
File f = new File(filePath);
String fileName = f.getName();
// fileName == "song.mp3"

In your case:

public class Songs {
    private String title; // renamed from "songTitle"
    private String path;  // renamed from "songAddress"
    private String fileName; // the file name of the song

    public Songs(String title, String path){
        this.title = title;
        this.path = path;
        File file = new File(path);
        String fileName = f.getName();
        this.fileName = fileName;
    }

    public String getTitle(){
        return title;
    }

    public String getPath(){
        return path;
    }

    public String getFileName(){
        return fileName;
    }
}
