我用sqlite打开都能看到，可是运行总是找不到表，打开也没错

 db = SQLiteDatabase.openOrCreateDatabase("data/data/com.example.music_demo/music_type.db", null);
    Cursor cursor = db.rawQuery("SELECT common FROM eq WHERE type = 'style'", null);
    cursor.moveToFirst();
    Toast.makeText(MainActivity.this, cursor.getString(0), Toast.LENGTH_LONG).show();
