充分利用mediastore音频文件路径或URI

Question

我正在上面列出了所有设备上的歌曲到屏幕上点击它们打开一个共享的意图，其中的歌曲/音频文件可以在不同设备上通过像蓝牙，WhatsApp的等不同的方法来共享，但我不能申请获得从mediastore音频文件的文件路径或位置。

这就是我如何得到我的songs-

public void getSongList() {
    //retrieve song info
    ContentResolver musicResolver = getActivity().getContentResolver();
    Uri musicUri = android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    Cursor musicCursor = musicResolver.query(musicUri, null, null, null, null);
    //iterate over results if valid
    if(musicCursor!=null && musicCursor.moveToFirst()){
        //get columns
        int titleColumn = musicCursor.getColumnIndex
                (android.provider.MediaStore.Audio.Media.TITLE);
        int idColumn = musicCursor.getColumnIndex
                (android.provider.MediaStore.Audio.Media._ID);
        int artistColumn = musicCursor.getColumnIndex
                (android.provider.MediaStore.Audio.Media.ARTIST);
        int albumId = musicCursor.getColumnIndex
                (MediaStore.Audio.Media.ALBUM_ID);
        int data= musicCursor.getColumnIndex(MediaStore.Audio.Media.DATA);
        int albumkey=musicCursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_KEY);
        //add songs to list
        do {
            long thisId = musicCursor.getLong(idColumn);
            String thisTitle = musicCursor.getString(titleColumn);
            String thisArtist = musicCursor.getString(artistColumn);
            long thisalbumId = musicCursor.getLong(albumId);
            String thisdata= musicCursor.getString(data);
            String AlbumKey = musicCursor.getString(albumkey);
            tempSongList.add(new Song(thisId, thisTitle, thisArtist, thisalbumId, thisdata, AlbumKey));

        }
        while (musicCursor.moveToNext());

    }
}

我存储中的所有歌曲类歌曲的ArrayList的是如下─

package com.musicplayer;

import android.content.ContentUris;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.net.Uri;
import android.os.Parcel;
import android.os.ParcelFileDescriptor;
import android.os.Parcelable;

import java.io.FileDescriptor;
import java.io.FileNotFoundException;
import java.io.Serializable;

public class Song  implements Parcelable {
private long id;
private String title;
private String artist, data, albumkey;
private long alid;

public Song(long songID, String songTitle, String songArtist, long albumID, String thisdata, String AlbumKey) {
    id=songID;
    title=songTitle;
    artist=songArtist;
    alid=albumID;
    data=thisdata;
    albumkey=AlbumKey;

}
public Song(){

}
public long getID(){return id;}
public String getTitle(){return title;}
public String getArtist(){return artist;}
public long getAlbumID(){return alid;}
public String getPath(){return data;}
public String getAlbumKey(){return albumkey;}

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(title);
    dest.writeString(artist);
    dest.writeLong(alid);
    dest.writeLong(id);
    dest.writeString(data);
    dest.writeString(albumkey);
}
public static final Parcelable.Creator<Song> CREATOR = new Parcelable.Creator<Song>() {
    public Song createFromParcel(Parcel in) {
        Song song = new Song();
        song.title = in.readString();
        song.artist = in.readString();
        song.alid = in.readLong();
        song.id = in.readLong();
        song.data= in.readString();
        song.albumkey=in.readString();
        return song;
    }

    public Song[] newArray(int size) {
        return new Song[size];
    }
};
}

现在，当对某一首歌在用户点击我在做什么，分享是这个 -

String sharePath = currSong.getPath();
    Uri uri = Uri.parse(sharePath);
    Intent share = new Intent(Intent.ACTION_SEND);
    share.setType("audio/*");
    share.putExtra(Intent.EXTRA_STREAM, uri);
    context.startActivity(Intent.createChooser(share, "Share Sound File"));

凡currSong是哪个用户点击了歌曲。我在哪里错了。

Answer 1

所以我想通了，在代码中的问题，一切都只是URI中产生部分正确的，我不得不添加“文件：///”和它的工作。所以我取代

Uri uri= Uri.parse(song.getPath());

同

Uri uri= Uri.parse("file:///"+song.getPath());

和它的工作般的魅力！希望别人会发现这很有用！
