Question

我在我的主要活动中有一个导航视图并且有一些项目，问题是当我点击项目项目名称字段时会填充蓝色背景。我如何解决该问题

代码： -

NavigationView m_Navigation = (NavigationView) findViewById(R.id.nav_view);
    m_Navigation.setNavigationItemSelectedListener(this);
public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();
    if (id == R.id.nav_wallet) {
        // Handle the camera action
        Intent wallet = new Intent(this, CMyWalletScreen.class);
        startActivity(wallet);
    } else if (id == R.id.referandEarn) {
        Intent refer = new Intent(this, CReferAndEarnScreen.class);
        startActivity(refer);
    } else if (id == R.id.myProfile) {
        Intent profile = new Intent(this, CMyProfile.class);
        startActivity(profile);
    } else if (id == R.id.setting) {
        Intent setting = new Intent(this, CSettingScreen.class);
        startActivity(setting);
    } else if (id == R.id.LogOut) {
        showdialog();
    }
    m_Drawer.closeDrawer(GravityCompat.START);
    return true;
}

样式文件： -

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary</item>
    <item name="colorAccent">@color/accent</item>
    <item name="android:statusBarColor" tools:ignore="NewApi">@color/primary_dark</item>

</style>

我认为你的问题已解决：

您的xml文件处于更改

//在标题

中添加此行

xmlns:app="http://schemas.android.com/apk/res-auto"

//在导航视图中添加此代码后

<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:itemBackground="@color/drawer_item" />

//创建文件夹res / color

之后

//创建文件res / color / drawer_item.xml

之后

//在drawer_item.xml中添加此代码

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorPrimary"
        android:state_checked= "true"
        android:drawable="#0098D9"/> //your color code
    <item
        android:color="@android:color/white"
        android:drawable="@android:color/white"/>
</selector>

当导航查看项目封面与背景蓝色点击在Android？
