我可以改变一个菜单项的背景颜色在安卓?
如果有人对此有任何解决方案,请让我知道。最后一个选项显然是自定义,但是否有任何方法可以在不自定义的情况下更改文本颜色。

我找到了,尤利卡!!
在你的应用主题中:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">@style/ActionBarTheme</item>
<!-- backward compatibility -->
<item name="actionBarStyle">@style/ActionBarTheme</item>
</style>
这是你的动作栏主题:
<style name="ActionBarTheme" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="android:background">@color/actionbar_bg_color</item>
<item name="popupTheme">@style/ActionBarPopupTheme</item
<!-- backward compatibility -->
<item name="background">@color/actionbar_bg_color</item>
</style>
这是你弹出的主题:
<style name="ActionBarPopupTheme">
<item name="android:textColor">@color/menu_text_color</item>
<item name="android:background">@color/menu_bg_color</item>
</style>

在Kotlin中我写了这些扩展:
fun MenuItem.setTitleColor(color: Int) {
val hexColor = Integer.toHexString(color).toUpperCase().substring(2)
val html = "<font color='#$hexColor'>$title</font>"
this.title = html.parseAsHtml()
}
@Suppress("DEPRECATION")
fun String.parseAsHtml(): Spanned {
return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Html.fromHtml(this, Html.FROM_HTML_MODE_LEGACY)
} else {
Html.fromHtml(this)
}
}
并像这样使用:
menu.findItem(R.id.main_settings).setTitleColor(Color.RED)
我是这样编程的:
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.changeip_card_menu, menu);
for(int i = 0; i < menu.size(); i++) {
MenuItem item = menu.getItem(i);
SpannableString spanString = new SpannableString(menu.getItem(i).getTitle().toString());
spanString.setSpan(new ForegroundColorSpan(Color.BLACK), 0, spanString.length(), 0); //fix the color to white
item.setTitle(spanString);
}
return true;
}
要更改菜单项文本颜色,请使用下面的代码
<style name="AppToolbar" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:itemTextAppearance">@style/menu_item_color</item>
</style>
在哪里
<style name="menu_item_color">
<item name="android:textColor">@color/app_font_color</item>
</style>
Options menu in android can be customized to set the background or change the text appearance. The background and text color in the menu couldn’t be changed using themes and styles. The android source code (data\res\layout\icon_menu_item_layout.xml)uses a custom item of class “com.android.internal.view.menu.IconMenuItem”View for the menu layout. We can make changes in the above class to customize the menu. To achieve the same, use LayoutInflater factory class and set the background and text color for the view.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.my_menu, menu);
getLayoutInflater().setFactory(new Factory() {
@Override
public View onCreateView(String name, Context context, AttributeSet attrs) {
if (name .equalsIgnoreCase(“com.android.internal.view.menu.IconMenuItemView”)) {
try{
LayoutInflater f = getLayoutInflater();
final View view = f.createView(name, null, attrs);
new Handler().post(new Runnable() {
public void run() {
// set the background drawable
view .setBackgroundResource(R.drawable.my_ac_menu_background);
// set the text color
((TextView) view).setTextColor(Color.WHITE);
}
});
return view;
} catch (InflateException e) {
} catch (ClassNotFoundException e) {}
}
return null;
}
});
return super.onCreateOptionsMenu(menu);
}
您可以通过编程方式设置颜色。
private static void setMenuTextColor(final Context context, final Toolbar toolbar, final int menuResId, final int colorRes) {
toolbar.post(new Runnable() {
@Override
public void run() {
View settingsMenuItem = toolbar.findViewById(menuResId);
if (settingsMenuItem instanceof TextView) {
if (DEBUG) {
Log.i(TAG, "setMenuTextColor textview");
}
TextView tv = (TextView) settingsMenuItem;
tv.setTextColor(ContextCompat.getColor(context, colorRes));
} else { // you can ignore this branch, because usually there is not the situation
Menu menu = toolbar.getMenu();
MenuItem item = menu.findItem(menuResId);
SpannableString s = new SpannableString(item.getTitle());
s.setSpan(new ForegroundColorSpan(ContextCompat.getColor(context, colorRes)), 0, s.length(), 0);
item.setTitle(s);
}
}
});
}
