The following lines should be updated in app -> main -> res -> values -> Styles.xml
应在app -> main -> res -> values -> Styles.xml 中更新以下几行
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
<item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
</style>
<!-- Style to replace actionbar overflow icon. set item 'android:actionOverflowButtonStyle' in AppTheme -->
<style name="MyActionButtonOverflow" parent="android:style/Widget.Holo.Light.ActionButton.Overflow">
<item name="android:src">@drawable/ic_launcher</item>
<item name="android:background">?android:attr/actionBarItemBackground</item>
<item name="android:contentDescription">"Lala"</item>
</style>
This is how it can be done. If you want to change the overflow icon in action bar

I got a simpler solution which worked perfectly for me :
我得到了一个更简单的解决方案，它非常适合我：
Drawable drawable = ContextCompat.getDrawable(getApplicationContext(),R.drawable.change_pass);
toolbar.setOverflowIcon(drawable);

1) Declare menuin your class.
1）menu在你的课堂上声明。
private Menu menu;
2) In onCreateOptionsMenudo the following :
2）onCreateOptionsMenu执行以下操作：
public boolean onCreateOptionsMenu(Menu menu) {
this.menu = menu;
getMenuInflater().inflate(R.menu.menu_orders_screen, menu);
return true;
}
3) In onOptionsItemSelected, get the item and do the changes as required(icon, text, colour, background)
3）在onOptionsItemSelected，获取项目并根据需要进行更改（图标，文本，颜色，背景）
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_search) {
return true;
}
if (id == R.id.ventor_status) {
return true;
}
if (id == R.id.action_settings_online) {
menu.getItem(0).setIcon(getResources().getDrawable(R.drawable.history_converted));
menu.getItem(1).setTitle("Online");
return true;
}
if (id == R.id.action_settings_offline) {
menu.getItem(0).setIcon(getResources().getDrawable(R.drawable.cross));
menu.getItem(1).setTitle("Offline");
return true;
}
return super.onOptionsItemSelected(item);
}
Note:
If you have 3 menu items :
menu.getItem(0) = 1 item,
menu.getItem(1) = 2 iteam,
menu.getItem(2) = 3 item
注意：
如果您有 3 个菜单项：
menu.getItem(0) = 1 item,
menu.getItem(1) = 2 itam,
menu.getItem(2) = 3 item
Based on this make the changes accordingly as per your requirement.
在此基础上，根据您的要求进行相应的更改。

Drawable drawable = ContextCompat.getDrawable(getApplicationContext(),
R.drawable.change_pass);
toolbar.setOverflowIcon(drawable);

Use the example of Syed Raza Mehdi and add on the Application themethe name=actionOverflowButtonStyleparameter for compatibility.
使用赛义德·拉扎迈赫迪的例子，并添加上Application theme的name=actionOverflowButtonStyle兼容性参数。
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
<item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
<!-- For compatibility -->
<item name="actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
</style>

Change your custom overflow icon of Actionbar in styles.xml
<resources> <!-- Base application theme. --> <style name=“MyTheme" parent="@android:style/Theme.Holo"> <!-- Pointer to Overflow style DONT forget! --> <item name="android:actionOverflowButtonStyle">@style/MyOverFlow</item> </style> <!-- Styles --> <style name="MyOverFlow" parent="@android:style/Widget.Holo.ActionButton.Overflow"> <item name="android:src">@drawable/ic_your_action_overflow</item> </style> </resources>Put custom theme "MyTheme" in application tag of AndroidManifest.xml
<application android:name="com.example.android.MainApp" android:theme="@style/AppTheme"> </application>
在styles.xml 中更改Actionbar 的自定义溢出图标
<resources> <!-- Base application theme. --> <style name=“MyTheme" parent="@android:style/Theme.Holo"> <!-- Pointer to Overflow style DONT forget! --> <item name="android:actionOverflowButtonStyle">@style/MyOverFlow</item> </style> <!-- Styles --> <style name="MyOverFlow" parent="@android:style/Widget.Holo.ActionButton.Overflow"> <item name="android:src">@drawable/ic_your_action_overflow</item> </style> </resources>将自定义主题“MyTheme”放在 AndroidManifest.xml 的应用程序标签中
<application android:name="com.example.android.MainApp" android:theme="@style/AppTheme"> </application>

Check this out this may work: (in kotlin)
toolBar.menu.getItem(indexNumber).setIcon(R.drawable.ic_myIcon)
检查一下这可能有效：（在 kotlin 中）
toolBar.menu.getItem(indexNumber).setIcon(R.drawable.ic_myIcon)

If you want to change icon/title menu in the actionbar/toolbar programmatically,
如果要以编程方式更改操作栏/工具栏中的图标/标题菜单，
STEP by STEP
一步步
- Declare Menu in class
- 在课堂上声明菜单
private var mMenu: Menu? = null
私有变量 mMenu：菜单？= 空
Overide onCreateOptionsMenu method and find item so you need to change
override fun onCreateOptionsMenu(menu: Menu?): Boolean { mMenu = menu menuInflater.inflate(R.menu.menu, menu) if (mIsFavorite){ mMenu?.findItem(R.id.action_favorite)?.icon = yourDrawable } else { mMenu?.findItem(R.id.action_favorite)?.icon = yourDrawable } return true}
Use invalidateOptionsMenu() to update some changes in menu after onCreateOptionsMenu executed. This method will re-create menu
覆盖 onCreateOptionsMenu 方法并找到项目，因此您需要更改
override fun onCreateOptionsMenu(menu: Menu?): Boolean { mMenu = menu menuInflater.inflate(R.menu.menu, menu) if (mIsFavorite){ mMenu?.findItem(R.id.action_favorite)?.icon = yourDrawable } else { mMenu?.findItem(R.id.action_favorite)?.icon = yourDrawable } return true}
在 onCreateOptionsMenu 执行后，使用 invalidateOptionsMenu() 更新菜单中的一些更改。此方法将重新创建菜单
