Android custom Spinner font, color, size, and androidspinner

Yesterday, I encountered confusion about the color, Font, and size of the Spinner in my project. So I will summarize this knowledge today. This is actually very simple. To change the font, color, and size, simply do not use the style that comes with the system. Write a layout call with your own exceptions. That's what I do. In this example, you can also use the following two methods to bring up a menu: drop-down box and pop-up box. You can load data sources in two ways. The following describes the code.

Custom_spiner_text_item.xml

Custom_spinner_dropdown_item.xml

<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/checkedTextViewCustom"    style="?android:attr/spinnerDropDownItemStyle"    android:layout_width="match_parent"    android:layout_height="50dp"    android:ellipsize="marquee"    android:singleLine="true"    android:textAlignment="inherit"    android:textColor="#222288"    android:textSize="16sp" />

Activity_main.xml

<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/tools" android: layout_width = "match_parent" android: layout_height = "match_parent" android: orientation = "vertical"> <LinearLayout android: layout_width = "match_parent" android: layout_height = "60dp" android: gravity = "center_vertical"> <TextView android: id = "@ + id/textView1" android: layout_width = "116dp" android: layout_height = "wrap_content" android: text = "Custom drop-down box:" android: textSize = "16sp"/> <Spinner android: id = "@ + id/spinner1" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_weight = "1"/> </LinearLayout> <linelayout android: layout_width = "match_parent" android: layout_height = "wrap_content" android: gravity = "center_vertical"> <TextView android: id = "@ + id/textView2" android: layout_width = "116dp" android: layout_height = "wrap_content" android: text = "Custom pop-up box:" android: textSize = "16sp"/> <Spinner android: id = "@ + id/spinner2" android: layout_width = "202dp" android: layout_height = "wrap_content" android: spinnerMode = "dialog"/> </LinearLayout>

When you configure a Spinner in xml, it is in the drop-down box by default.

In the displayed dialog box, add this android: spinnerMode = "dialog"

Use other listeners to trigger the spinner statement: mspinner. receivmclick ();
