答案 0 :(得分：0)
为Spinner创建适配器时，会提供自定义布局而不是预定义布局
创建名为 spinner_row.xml
的xml<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/cust_view"
android:layout_width="match_parent"
android:textColor="@color/black"
android:textSize="12sp"
android:layout_height="36dp"
android:gravity="left|center_vertical"/>
在这里，您可以通过修改此textview来更改微调器中元素的颜色文本大小和宽度和高度
在创建适配器
时使用它ArrayAdapter<String> adapter=new ArrayAdapter<String>(context, R.layout.spinner_row,yourlist);
最后一项任务是常规的
spinner.setAdapter(adapter);
我希望这会对你有所帮助。
