How to change background color popup menu android
提问by user3172337
I generate each option of menu from querying database. Here is my code.
我从查询数据库中生成菜单的每个选项。这是我的代码。
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());
}
Everything is okay, but the problem is how to change color of option menu or background color of popup menu (from black to white), Is it possible ? Thanks
一切正常，但问题是如何更改选项菜单的颜色或弹出菜单的背景颜色（从黑色到白色），这可能吗？谢谢

如果您使用的是 AppCompact-v7，那么您可以设置如下样式的 PopupMenu：

<item name="popupMenuStyle">@style/popupMenuStyle</item>
</style>

在这里，我想更改特定活动中的弹出菜单背景，因此将 theme(android:theme="@style/AppTheme") 与活动声明一起应用，它肯定会起作用。使用此代码创建弹出菜单的另一件重要事情 PopupMenu popup = new PopupMenu(your activity, viewObj);
