android的spinner设置宽高和里面的字体设置大小

简单用例参考: java代码里这样

ArrayAdapter<MemberCardType> adapter = new ArrayAdapter<MemberCardType>( MemberAddOpenCardActivity.this, R.layout.simple_spinner_item, mCardTypeList); Spinner spinner = findViewById(R.id.spinner3); spinner.setAdapter(adapter);

关键是引入的这个布局R.layout.simple_spinner_item 就是新建的simple_spinner_item.xml文件

<?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/text1" style="?android:attr/spinnerItemStyle" android:layout_width="match_parent" android:layout_height="40dp" android:ellipsize="marquee" android:singleLine="true" android:textAlignment="inherit" android:textSize="20sp" /> `` 宽:android:layout_width="match_parent" 高:android:layout_height="40dp" 字体大小:`android:textSize="20sp"
