Spinner获取SQLite数据库数据生成自定义下拉框（下拉选择收货地址）

Activity代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_display);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);


    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab2);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });

    adspinnner = (Spinner)super.findViewById(R.id.spinner);
    sqLiteDatabase = SQLiteDatabase.openOrCreateDatabase(this.getFilesDir().toString()+"/mydb.db3",null);
    //插入数据并显示在ListView中
    try{
        //sqLiteDatabase.execSQL("insert into address_table_1 values(null,?,?,?,?)",new String[]{adname,adphone,adad,auto});
        cursor = sqLiteDatabase.rawQuery("select * from address_table_1",null);

    }catch(SQLiteException r)
    {
        sqLiteDatabase.execSQL("create table address_table_1 (_id integer primary key autoincrement," +
                " name varchar(50),phone varchar(50),address varchar(255),auto varchar(50))");//
        //sqLiteDatabase.execSQL("insert into address_table_1 values(null,?,?,?,?)",new String[]{adname,adphone,adad,auto});
        cursor = sqLiteDatabase.rawQuery("select * from address_table_1",null);
    }
    SimpleCursorAdapter simpleCursorAdapter = new SimpleCursorAdapter(this,R.layout.ad_list,cursor,new String[]{"name","phone","address","auto"},//
            new int[]{R.id.textView15,R.id.textView14,R.id.textView16,R.id.textView19}, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);

    simpleCursorAdapter.setDropDownViewResource(R.layout.ad_list);
   //添加该句后才会使用自定义样式 
    adspinnner.setAdapter(simpleCursorAdapter);
