如何更改背景颜色弹出菜单android [英] How to change background color popup menu android

问题描述

我从查询数据库中生成菜单的每个选项。
这是我的代码。

I generate each option of menu from querying database. Here is my code.

final PopupMenu popupMenu = new PopupMenu(getBaseContext(), v); 
SQLiteDatabase db = AdapterDb.getReadableDatabase(); 
Cursor cursor = db.rawQuery(sql, null);
int ctritem = 0;
if (cursor.moveToFirst()) {
    popupMenu.getMenu().add(Menu.NONE, ctritem, Menu.NONE, "ALL ITEMS"); 
    do {
        ctritem++;   
        popupMenu.getMenu().add(Menu.NONE, ctritem, Menu.NONE, cursor.getString(0)); 
    } while (cursor.moveToNext());
}

一切正常，但问题是如何更改选项菜单的颜色背景颜色的弹出菜单（从黑到白），是可能吗？

推荐答案

将popupMenu样式添加到AppTheme：

Add popupMenu style to ur AppTheme:

<style name="AppTheme" parent="android:Theme.Light">
    <item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>

<style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
    <item name="android:popupBackground">@android:color/white</item>
</style>

manifest.xml：

manifest.xml:

 <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
.............
</application>
