如何创建垂直的BottomNavigationView android?

问题描述

我有一个活动，该活动的顶部有4个片段，底部有4个项目的BottomNavigationView.在移动设备上运行正常.当我使用LANDASCAPE平板电脑时，我想将BottomNavigationView沿垂直方向移动到活动的左侧，如下所示.

I have an activity that have 4 fragment on top and BottomNavigationView with 4 items on bottom. It is working fine in mobile devices. When i go for tablet with LANDASCAPE i want to move that BottomNavigationView to left of the activity with vertical orientation like below.

这是使用BottomNavigationView可以实现的，还是应该转到NavigationMenu android.

Is this achievable using BottomNavigationView or should I go for NavigationMenu android.

推荐答案

好吧，我通过调整方向更改和移动了一些视图来完成了BottomNavigationView所需的操作.首先，为了改变方向，我将其添加到了AndroidManifest的Activity标签中

Well i managed to do it, what you want with BottomNavigationView, by some tweaking in orientation change and moving some views.Firstly for tap into orientation change i added this to Activity tag in AndroidManifest

android:configChanges="orientation|screenSize"

在我的活动中，我添加了

and in my Activity i added following

 @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
            Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
            BottomNavigationView navigation= (BottomNavigationView) findViewById(R.id.navigation);
            navigation.setRotation(90f);
            navigation.getLayoutParams().width=480;
            navigation.requestLayout();
            navigation.setY(600f);
            navigation.setX(-435f);
           // navigation.requestLayout();
            BottomNavigationMenuView menuView = (BottomNavigationMenuView) navigation.getChildAt(0);
            for (int i = 0; i < menuView.getChildCount(); i++) {
                final View iconView = menuView.getChildAt(i);
                iconView.setRotation(-90f);
            }
        } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
            recreate();
        }
    }

我的XML是

<?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"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/message"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        android:layout_marginBottom="8dp"
        android:text="@string/title_home"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="0dp"
        android:layout_marginEnd="0dp"
        android:background="?android:attr/windowBackground"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:menu="@menu/navigation" />

</android.support.constraint.ConstraintLayout>

当然，您必须根据手机的需要更改navigation.getLayoutParams().width，setX和setY.您可以创建一个函数来计算位置.抱歉，它是在白天的10:30，并且整夜都在编码，所以要休息一下，所以无法编写该函数.但是，如果您愿意，我会编写该函数.这是我为手机Vivo Y51L工作的结果，您可以查看屏幕截图.

Definitely, you have to change navigation.getLayoutParams().width, setX and setY according to your phone needs. You can create a function to calculate the position. Sorry its 10:30 in the day and was coding all night so going for rest, so couldn't write that function. But i would write that function if you want. Its what i got working for my phone Vivo Y51L, you can have look at screenshots.
