Android导航抽屉 - 将列表替换为其他列表onClick

标签: android material-design navigation-drawer navigationview android-navigationview

我正在尝试在材料设计中实现一个简单的导航抽屉,因此我的抽屉顶部有一个标题和一些文字项(A:CompactHeader Drawer,...)(见图1)。单击标题图像时,应打开一个列表(B:mikepenz@gmail.com,...)并“覆盖”我现有的文本项(A)(见图2)。如果选择了文本项(B),则原始列表(A)应该返回其原始位置,并且(B)不再可见(参见图1)。

注意:这些截图来自教程,但代码太混乱了。我正在寻找一个相对简单的解决方案......我在考虑碎片,但我不知道这是否是解决这个问题的正确方法。

此用例不存在API,这意味着应该手动处理。您应该通过app:headerLayout提供自定义布局,而不是从资源(<?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" android:id="@+id/drawer" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true"> <View android:layout_width="match_parent" android:layout_height="match_parent" android:background="#7e25d1" /> <android.support.design.widget.NavigationView android:id="@+id/navigation_view" android:layout_width="300dp" android:layout_height="match_parent" android:layout_gravity="start" app:headerLayout="@layout/navigation_view" /> </android.support.v4.widget.DrawerLayout> )中提取菜单项,模拟这些菜单项:此布局包含使用普通布局构建的标题部分和菜单项部分。 / p>

所以,定义了你的根布局:

navigation_view.xml

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <include android:id="@+id/include" layout="@layout/header" android:layout_width="match_parent" android:layout_height="190dp" /> <FrameLayout android:id="@+id/frame" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout> 的位置:

header.xml

<?xml version="1.0" encoding="utf-8"?> <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="190dp" android:background="@drawable/background_material"> <de.hdodenhof.circleimageview.CircleImageView android:id="@+id/profile_image" android:layout_width="60dp" android:layout_height="0dp" android:layout_marginLeft="24dp" android:layout_marginStart="16dp" android:layout_marginTop="40dp" android:src="@drawable/profile" app:civ_border_color="#FF000000" app:layout_constraintDimensionRatio="h,1:1" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" /> <TextView android:id="@+id/username" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingBottom="4dp" android:text="John Doe" android:textColor="#FFF" android:textSize="14sp" android:textStyle="bold" app:layout_constraintBottom_toTopOf="@+id/email" app:layout_constraintLeft_toLeftOf="@+id/profile_image" app:layout_constraintStart_toStartOf="@+id/profile_image" /> <TextView android:id="@+id/email" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="8dp" android:text="john.doe@gmail.com" android:textColor="#fff" android:textSize="14sp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toLeftOf="@+id/username" app:layout_constraintStart_toStartOf="@+id/username" /> <ImageButton android:id="@+id/arrow" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="16dp" android:layout_marginEnd="16dp" android:background="?selectableItemBackgroundBorderless" android:src="@drawable/ic_arrow_drop_down_black_24dp" android:tint="#ffffff" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" /> </android.support.constraint.ConstraintLayout> 是:


    public class MainActivity extends AppCompatActivity {

        boolean initial = true;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
            View headerView = navigationView.getHeaderView(0);
            ImageButton arrow = headerView.findViewById(R.id.arrow);
            ViewGroup frame = headerView.findViewById(R.id.frame);
            frame.setOnClickListener(v -> toggle(arrow, frame));
            changeContent(frame);
            arrow.setOnClickListener(v -> toggle(arrow, frame));
        }

        private void toggle(ImageButton arrow, ViewGroup frame) {
            initial = !initial;
            arrow.setImageDrawable(ContextCompat.getDrawable(MainActivity.this, initial ? R.drawable.ic_arrow_drop_down_black_24dp : R.drawable.ic_arrow_drop_up_black_24dp));
            changeContent(frame);
        }

        private void changeContent(ViewGroup frame) {
            frame.removeAllViews();
            getLayoutInflater().inflate(initial ? R.layout.content1 : R.layout.content2, frame);
        }

    }

然后在活动中:

content_1

您将获得此输出:

提供content_2和{{1}}布局文件的布局以适合您的使用案例。

非常感谢你!基于@azizbekian和@Mohsen的答案,我将分享我的整体解决方案,该解决方案完美运行并提供理想的结果。

所以,定义了我的根布局:

<?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:background="@color/colorFlatWhite"
        android:fitsSystemWindows="true"

        app:itemIconTint="@color/colorFlatDarkerGray"
        app:itemTextColor="@color/colorFlatDarkerGray"
        app:menu="@menu/navigation" />


</android.support.v4.widget.DrawerLayout>

nav_header_main.xml的位置:

<?xml version="1.0" encoding="utf-8"?>

            android:src="@drawable/ic_home"
            android:tint="@color/colorFlatFontColorBlack" />
    </android.support.v7.widget.CardView>


    <TextView
        android:id="@+id/username"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingBottom="4dp"
        android:text="John Doe"
        android:textColor="#FFF"
        android:textSize="14sp"
        android:textStyle="bold"
        app:layout_constraintBottom_toTopOf="@+id/email"
        app:layout_constraintLeft_toLeftOf="@+id/profile_image"
        app:layout_constraintStart_toStartOf="@+id/profile_image" />

    <TextView
        android:id="@+id/email"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dp"
        android:text="john.doe@gmail.com"
        android:textColor="#fff"
        android:textSize="14sp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="@+id/username"

    <ImageButton

</android.support.constraint.ConstraintLayout>

然后在活动中:

    NavigationView navigationView;
     @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        navigationView = (NavigationView) findViewById(R.id.nav_view);
        View headerView = navigationView.getHeaderView(0);
        final ImageButton arrow = (ImageButton) headerView.findViewById(R.id.arrow);
        arrow.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                toggle(arrow);
            }
        });
    }

    boolean initial=true;
    private void toggle(ImageButton arrow) {
        initial = !initial;
        arrow.setImageDrawable(ContextCompat.getDrawable(MainActivity.this, initial ? R.drawable.ic_arrow_downward_black_24dp : R.drawable.ic_arrow_upward_black_24dp));
        if(initial)
        {
            navigationView.getMenu().clear();
            navigationView.inflateMenu(R.menu.navigation);
            SetLeftMenuNavLabels();

        }else
        {
            navigationView.getMenu().clear();
            navigationView.getMenu().add("account1@gmail.com").setIcon(  R.drawable.ic_home);
            navigationView.getMenu().add("account2@gmail.com").setIcon(  R.drawable.ic_home);
            navigationView.getMenu().add("Add New Account").setIcon(  R.drawable.ic_add);
            navigationView.getMenu().add("Manage Accounts").setIcon(  R.drawable.ic_settings);
        }
    }

这是期望的输出。谢谢你们! enter image description here
