Question

我的问题是我的代码无法正常工作。我的资产/专题歌文件夹中有100多个mp3商店。

flAnthem = c.getString(c.getColumnIndex(KEY_ANTHEM));
flAnthemSDCard = c.getString(c.getColumnIndex(KEY_ANTHEM_SDCARD));

AssetManager assetManager= getAssets();
InputStream inputStream = null;
try{
    inputStream = assetManager.open("anthem/" + flAnthem);
    mediaPlayer.setDataSource(String.valueOf(inputStream));
    mediaPlayer.prepare();
    mediaPlayer.start();
}catch(IOException e){
    e.printStackTrace();
}

Answer 1

替换

inputStream = assetManager.open("anthem/" + flAnthem);
mediaPlayer.setDataSource(String.valueOf(inputStream)); //DataSource is not correctly setted.

使用AssetFileDescriptor

flAnthem = c.getString(c.getColumnIndex(KEY_ANTHEM)) + ".mp3"; // don't forget extension 

AssetFileDescriptor descriptor = getAssets().openFd("anthem/"+mediaName);
mediaPlayer.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());

顺便说一句
