Answer 1

在onItemClickListener中添加此代码.

listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {                 
                TextView txtView=(TextView)view.findViewById(R.id.txt_view);
                String fname=txtView.getText().toString().toLowerCase();

                                int resID=getResources().getIdentifier(fname, "raw", getPackageName());

                              MediaPlayer mediaPlayer=MediaPlayer.create(this,resID);
                    mediaPlayer.start();
            }
        });

试试这个来自raw ::

MediaPlayer mPlayer2;
mPlayer2= MediaPlayer.create(this, R.raw.bg_music_wav);
        mPlayer2.start();

清单文件中的权限::

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

更新::

public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {     
  MediaPlayer mPlayer2;
if(position==1)
{
    mPlayer2= MediaPlayer.create(this, R.raw.song1);
            mPlayer2.start();
}else it() .....
}

Answer 3

mVideoView = (VideoView) findViewById(R.id.Video_FrontPage);
uri = Uri.parse("android.resource://com.urPackageName/" + R.raw.welcom_video);
mVideoView.setVideoURI(uri);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
mVideoView.start();

希望这对您有帮助。
