我寫一個音樂應用程序,在我得到從原始文件夾的歌曲,並在可用歌曲的名單顯示,一旦用戶點擊任何一首歌曲,打電話給另一個活動,即播放活動,這裏我提供了另一個選項,如:播放按鈕[播放該特定歌曲]哪個用戶通過MainActivity.java中的列表選擇了。如何播放特定音頻樂曲,而點擊播放按鈕
問題:
每當我做點擊播放按鈕從列表不同,不同的歌曲選擇後,它總是打最後一首歌我在給PlayActivity.java在這種情況下,你可以看到gayatri.mp3是最後一首歌曲,所以它每次都在播放這首歌曲,但我想播放該用戶選擇的特定歌曲。
PlayActivity.java:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_play);
if(mMedia != null){
mMedia.release();
}
Intent intent= getIntent();
// final String MusicID = intent.getStringExtra("vMusicID");
final String MusicName = intent.getStringExtra("vMusicName");
final TextView txtView = (TextView)findViewById(R.id.textView1);
txtView.setText(MusicName);
mMedia = MediaPlayer.create(this, R.raw.guitar);
mMedia = MediaPlayer.create(this, R.raw.helo);
mMedia = MediaPlayer.create(this, R.raw.msg);
mMedia = MediaPlayer.create(this, R.raw.roja);
mMedia = MediaPlayer.create(this, R.raw.gayatri);
final Button btn1 = (Button) findViewById(R.id.button1); // Play
// Start
btn1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
txtView.setText(MusicName);
mMedia.start();
startPlayProgressUpdater();
}
});
MainActivity.java:
MyArrList = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map;
/*** Rows 1 ***/
map = new HashMap<String, String>();
map.put("MusicID", "1");
map.put("MusicName", "Gayatri");
map.put("MusicPath", "gayatri.mp3");
MyArrList.add(map);
/*** Rows 2 ***/
map = new HashMap<String, String>();
map.put("MusicID", "2");
map.put("MusicName", "Guitar");
map.put("MusicPath", "guitar.mp3");
MyArrList.add(map);
/*** Rows 3 ***/
map = new HashMap<String, String>();
map.put("MusicID", "3");
map.put("MusicName", "Helo");
map.put("MusicPath", "helo.mp3");
MyArrList.add(map);
/*** Rows 4 ***/
map = new HashMap<String, String>();
map.put("MusicID", "4");
map.put("MusicName", "Msg");
map.put("MusicPath", "msg.mp3");
MyArrList.add(map);
/*** Rows 5 ***/
map = new HashMap<String, String>();
map.put("MusicID", "5");
map.put("MusicName", "Roja");
map.put("MusicPath", "roja.mp3");
MyArrList.add(map);
// listView1
final ListView lstView1 = (ListView)findViewById(R.id.listView1);
lstView1.setAdapter(new ImageAdapter(this));
