将关联到 ListView 单元格的数据传递给项目的另一个活动 onClick()

我是安卓编程的新手。我正在使用ListView自定义布局编写一个简单的音乐应用程序。列表中的每一行都有两个TextView's歌曲名和艺术家名。

我有两个活动，MainActivity 和 nowPlaying Activity，nowPlaying Activity 上有一个列表，它也有两个TextView's. 我想要实现的是，当我单击ListView（在主活动中）上的一个项目时，我想获取歌曲名称和艺术家姓名并将其设置TextView's为 nowPlaying 活动中的。

主要活动

public class MainActivity extends AppCompatActivity {

ListView listView;
ArrayList<Songs> song;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.songs_list);

    song = new ArrayList<Songs>();
    song.add(new Songs("Shape of you", "ed sheeran", "4:59"));
    song.add(new Songs("Energy", "avelino", "3:15"));
    song.add(new Songs("Wages", "bad sounds", "2:56"));
    song.add(new Songs("L'Hiver Indien", "baloji", "3:28"));
    song.add(new Songs("Faded Heart", "Borns", "4:59"));
    song.add(new Songs("King Ruby", "ider", "4:59"));
    song.add(new Songs("Drown", "kovic", "4:59"));
    song.add(new Songs("Supercut", "lorde", "4:59"));
    song.add(new Songs("&Run", "sir sly", "4:59"));
    song.add(new Songs("Live in the moment", "portugal. the man", "4:59"));

    SongAdapter adapter = new SongAdapter(this, song);

    listView = findViewById(R.id.list_view);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            TextView songName = findViewById(R.id.song_name);
            TextView artistName = findViewById(R.id.artist);
            Intent intent = new Intent(MainActivity.this, nowPlaying.class);
            intent.putExtra("name", listView.getItemAtPosition(i).toString());
            startActivity(intent);
        }
    });
    listView.setAdapter(adapter);
}

}

歌曲适配器

public class SongAdapter extends ArrayAdapter<Songs> {


public SongAdapter(Activity context, ArrayList<Songs> song) {
    // Here, we initialize the ArrayAdapter's internal storage for the context and the list.
    // the second argument is used when the ArrayAdapter is populating a single TextView.
    // Because this is a custom adapter for two TextViews and an ImageView, the adapter is not
    // going to use this second argument, so it can be any value. Here, we used 0.
    super(context, 0, song);
}

@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    //return super.getView(position, convertView, parent);
    View listItemView = convertView;
    if (listItemView == null) {
        listItemView = LayoutInflater.from(getContext()).inflate(
                R.layout.song_item, parent, false);
    }

    Songs currentSong = getItem(position);

    TextView songName = listItemView.findViewById(R.id.song_name);
    songName.setText(currentSong.getSongName());

    TextView artistName = listItemView.findViewById(R.id.artist);
    artistName.setText(currentSong.getArtistName());

    TextView time = listItemView.findViewById(R.id.time);
    time.setText(currentSong.geTime());

    return listItemView;
}
}

截屏

在屏幕截图（上面给出）中，每一行都有一个歌曲名称和另一个艺术家名称。单击该行时，我想获取名称并将其设置在其他活动上，并对艺术家姓名执行相同操作。

我希望ListView.

歌曲类

public class Songs {
private String mSongName;
private String mArtistName;
private String mTime;

public Songs(String songName, String artistName, String Time) {
    mSongName = songName;
    mArtistName = artistName;
    mTime = Time;
}

public String getSongName() {
    return mSongName;
}
public String getArtistName() {
    return mArtistName;
}

public String geTime() {
    return mTime;
}

}
