我有两个字符串数组:
String[] name ={ “Sound 1″, “Soundname 2″, “Chainsaw!”};
int[] sounds = {R.raw.sound1, R.raw.sound2, R.raw.chainsaw};
和一个列表视图:
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch(position) {
case 0: if(isplaying){audio.stop();} audio = MediaPlayer.create(context, R.raw.sound1); playSound();
break;
case 1: if(isplaying){audio.stop();} audio = MediaPlayer.create(context, R.raw.sound2); playSound();
break;
case 2: if(isplaying){audio.stop();} audio = MediaPlayer.create(context, R.raw.sound3); playSound();
break;
case 3: if(isplaying){audio.stop();} audio = MediaPlayer.create(context, R.raw.sound4); playSound();
break;
}
}
});
我使用此功能将资源声音文件设置为通知:
public boolean saveas(int ressound){
byte[] buffer=null;
InputStream fIn = getBaseContext().getResources().openRawResource(ressound);
int size=0;
try {
size = fIn.available();
buffer = new byte[size];
fIn.read(buffer);
fIn.close();
} catch (IOException e) {
// TODO Auto-generated catch block
return false;
}
String path="/sdcard/media/audio/ringtones/";
String filename="examplefile"+".ogg";
boolean exists = (new File(path)).exists();
if (!exists){new File(path).mkdirs();}
FileOutputStream save;
try {
save = new FileOutputStream(path+filename);
save.write(buffer);
save.flush();
save.close();
} catch (FileNotFoundException e) {
Toast.makeText(this, "ERRORE", Toast.LENGTH_SHORT).show();
return false;
} catch (IOException e) {
Toast.makeText(this, "ERRORE", Toast.LENGTH_SHORT).show();
return false;
}
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://"+path+filename)));
File k = new File(path, filename);
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "exampletitle");
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/ogg");
values.put(MediaStore.Audio.Media.ARTIST, "cssounds ");
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
values.put(MediaStore.Audio.Media.IS_ALARM, true);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
//Insert it into the database
this.getContentResolver().insert(MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath()), values);
return true;
}
此函数由上下文菜单调用,该菜单在长按列表视图的项目后显示。该函数将像这样调用:
saveas(R.raw.soundfile);
我的问题是:如何通过单击列表视图的哪个项目来获取不同的 id 或 R.raw.soundfile 到 saveas 函数?
