Android 简单数组适配器+下拉列表

下拉列表如果下面没位置了就变成上拉了
1.数据

String[] giftNumber = {"1", "10", "66", "99"};

2.适配器和下拉列表监听

//价格适配器
        spinnerNumber.setAdapter(new ArrayAdapter<>(mContext, R.layout.item_gift_number, R.id.tv_number, giftNumber));//里面参数是上下文,布局,布局里面的id,数据

        //价格下拉列表
        spinnerNumber.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView adapterView, View view, int position, long l) {
                for (int i1 = 0; i1 < giftNumber.length; i1++) {
                    mNumber = CastUtil.parseInt(giftNumber[position]);
                }
            }

            @Override
            public void onNothingSelected(AdapterView adapterView) {

            }
        });
