我有两个使用抽屉布局的布局,并且它们对NavigationView使用相同的代码,问题是它们之一更改了所选项目的颜色,而另一个却没有改变,即使它们是相同的精确代码。这是xml代码:

 <android.support.design.widget.NavigationView
    android:id="@+id/navigation_view_passager"
    android:layout_width="300dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:headerLayout="@layout/header"
    app:menu="@menu/menu_passager"  />

和Java用于第一种布局:

    @Override
public boolean onNavigationItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.acceuil_passager_item:
            toolbar.setTitle("Accueil");
            fm.beginTransaction().replace(R.id.frame_passager, new AcceuilPassagerFragment()).commit();
            break;

        case R.id.profile_item:
            toolbar.setTitle("Profil");
            fm.beginTransaction().replace(R.id.frame_passager, new PassagerProfileFragment()).commit();
            break;

        case R.id.historique_voyages_item_pass:
            toolbar.setTitle("Historique des voyages");
            fm.beginTransaction().replace(R.id.frame, new ListeTrajetsFragment()).commit();
            break;
        case R.id.futurs_voyages_item_pass:
            toolbar.setTitle("Futurs voyages");
            fm.beginTransaction().replace(R.id.frame_passager, new FutursVoyagesFragment()).commit();
            break;
        case R.id.log_out_item_pass:
            Intent intent = new Intent(PassagerActivity.this, LoginActivity.class);
            startActivity(intent);
            mAuth.signOut();
            finish();
            Log.d(TAG, "onNavigationItemSelected: " + (mAuth == null));
            break;

        default:
            break;
    }
    drawerLayout.closeDrawer(GravityCompat.START);
    return true;
}

和第二个布局的Java代码:

    @Override
public boolean onNavigationItemSelected(MenuItem item) {
    switch (item.getItemId()) {

        case R.id.acceuil_item_conducteur:
            setUpToolbar(item);
            fm.beginTransaction().replace(R.id.frame_conducteur, new AcceuilConducteurFragment()).commit();
            break;

        case R.id.profile_item_cond:
            setUpToolbar(item);
            fm.beginTransaction().replace(R.id.frame_conducteur, new ConducteurProfileFragment()).commit();
            break;

        case R.id.historique_voyages_item_cond:
            setUpToolbar(item);
            fm.beginTransaction().replace(R.id.frame_conducteur, new HistoriqueVoyagesFragment()).commit();
            break;

        case R.id.log_out_item_cond:
            Intent intent = new Intent(ConducteurActivity.this, LoginActivity.class);
            startActivity(intent);
            mAuth.signOut();
            finish();
            Log.d(TAG, "onNavigationItemSelected: " + (mAuth == null));
            break;
        default:
            break;
    }
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

and here is the first layout

and the 2nd one

ps:在两种布局中均选择了“配置文件”

2 个答案:

答案 0 :(得分:0)

对于导航视图,您必须编写一个颜色选择器,例如:nav_view_item_background

<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@color/primary" android:state_checked="true" />
        <item android:drawable="@android:color/transparent" />
</selector>

并设置app:itemBackground="@drawable/nav_view_item_background"

对于文本颜色,您必须具有相同的含义。创建一个textColor选择器并设置app:itemTextColor

用于抽屉布局 return true(在导航项目选择中)更改颜色和选择。

答案 1 :(得分:0)

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

<group
    android:id="@+id/menu_grp"
    android:checkableBehavior="single">

原来,checkableBehavior =“ single”是使菜单选择项处于选中状态的原因,而其他布局中则不存在
