さて、私は今、音を鳴らすためのボタンを作るために4時間ほど試しています. （サウンドボードアプリのように）。初心者なので変なミスあったらごめんなさい。
これは私の .java ファイルです。

Toast.makeText(this, "Long touch to save as Ringtones.", Toast.LENGTH_LONG).show();

switch(ressound){

//and so on and so on.....

String path="/sdcard/media/audio/ringtones/";
String filename=soundname+".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) {
// TODO Auto-generated catch block
return false;
} catch (IOException e) {
// TODO Auto-generated catch block
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, soundname);
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/ogg");
values.put(MediaStore.Audio.Media.ARTIST, "FRIDAY");
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);
String i = "Saved as Ringtone.";
Toast.makeText(getApplicationContext(), i,
Toast.LENGTH_LONG).show();
return true;
}
//----
}
そして、ここに私のレイアウトファイルがあります:
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:shrinkColumns="*" android:stretchColumns="*" android:background="#ffffff">
<!-- Row 2 with 3 columns -->
<TableRow
android:id="@+id/tableRow1"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<Button
android:id="@+id/btn1"
android:text="@string/button1.1"
android:layout_weight="1"
android:textColor="#000000"
android:padding="20dip"
android:gravity="center"/>
<Button
android:id="@+id/btn2"
android:layout_weight="1"

<Button
android:id="@+id/btn6"
android:text="@string/button1.3"
android:layout_weight="1"
android:textColor="#000000"
android:padding="20dip"
android:gravity="center"/>
</TableRow>
<!-- Row 2 with 3 columns -->
<TableRow
android:id="@+id/tableRow1"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<TextView
android:id="@+id/TextView04"
android:text="Row 2 column 1"
android:layout_weight="1"
android:textColor="#000000"
android:padding="20dip"
android:gravity="center"/>
<TextView
android:id="@+id/TextView04"
android:text="Row 2 column 2"
android:layout_weight="1"
android:textColor="#000000"
android:padding="20dip"
android:gravity="center"/>
<TextView
android:id="@+id/TextView04"
android:text="Row 2 column 3"
android:layout_weight="1"
android:textColor="#000000"
android:padding="20dip"
android:gravity="center"/>
</TableRow>
</TableLayout>
エラーを見つけるにはこれで十分だと思います。アプリは実行されていますが、サウンドは再生されていません。
前もって感謝します！
