我在导航抽屉中更改菜单项标题颜色时遇到问题我设置了itemTextColor但它只更改了项目的颜色而不是菜单的标题.
这是我的
activity_main.xml中
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/activity_main_drawer"
app:itemTextColor="#ffffff"
android:background="#283135"
/>
</android.support.v4.widget.DrawerLayout>
activity_main_drawer.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="@+id/nav_home"
android:icon="@mipmap/hospital"
android:title="Home"
/>
<item
android:id="@+id/nav_reminder"
android:icon="@mipmap/alarm"
android:title="Reminders" />
</group>
<item android:title="Tools">
<menu>
<item
android:id="@+id/nav_settings"
android:icon="@mipmap/settings"
android:title="Settings" />
<item
android:id="@+id/nav_help"
android:icon="@mipmap/information"
android:title="Help" />
<item
android:id="@+id/nav_about"
android:icon="@mipmap/team"
android:title="About Us" />
</menu>
</item>
</menu>
解决方法
给菜单项标题颜色和textSize创建这种方式..
<style name="TextAppearance44">
<item name="android:textColor">#FF0000</item>
<item name="android:textSize">20sp</item>
</style>
现在在activity_main_drawer.xml文件中为标题赋予id属性..
<item android:title="Tools"
android:id="@+id/tools">
<menu>
<item
android:id="@+id/nav_settings"
android:icon="@mipmap/settings"
android:title="Settings" />
<item
android:id="@+id/nav_help"
android:icon="@mipmap/information"
android:title="Help" />
<item
android:id="@+id/nav_about"
android:icon="@mipmap/team"
android:title="About Us" />
</menu>
</item>
现在在MainActivity.java文件中使用这种方式..
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
Menu menu = navigationView.getMenu();
MenuItem tools= menu.findItem(R.id.tools);
SpannableString s = new SpannableString(tools.getTitle());
s.setSpan(new TextAppearanceSpan(this,R.style.TextAppearance44),s.length(),0);
tools.setTitle(s);
navigationView.setNavigationItemSelectedListener(this);
它会将您的工具颜色更改为Red和TextSize为20sp ..实现它..
在我的情况下输出：
