Question

我正在尝试将工具栏放在底部。我已经尝试了一些提示，但工具栏位于顶部。

所以：我需要更改什么，以便我的工具栏显示在底部？

如果您需要更多代码 - 没有更多 - 或其他信息，只需这样说。

我的XML文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MapsActivity">
    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:map="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context="com.example.testingmapingmarker23.MapsActivity"
        />




   <android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        android:layout_alignParentBottom="true"
        android:layout_gravity="bottom"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

</LinearLayout>

和.java：

package com.example.testingmapingmarker23;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.AppCompatActivity;

import android.support.design.widget.FloatingActionButton;

import static com.example.testingmapingmarker23.R.id.map;

public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(map);
        mapFragment.getMapAsync(this);

        final Toolbar customToolbar = (Toolbar) findViewById(R.id.toolbar);



    }




    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
        mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);

    }





}

Styles.xml：

<resources>

    <!-- Base application theme. -->
    <!--<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        &lt;!&ndash; Customize your theme here. &ndash;&gt;

    </style>-->



    <style name="AppTheme.NoActionBar">

你可以使用像这样的相对布局，

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:map="http://schemas.android.com/apk/res-auto"
              xmlns:tools="http://schemas.android.com/tools"
              android:id="@+id/map"
              android:name="com.google.android.gms.maps.SupportMapFragment"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:layout_above="@+id/toolbar"
              tools:context="com.example.testingmapingmarker23.MapsActivity"
        />


    <android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:layout_alignParentBottom="true"
        android:layout_gravity="bottom"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

</RelativeLayout>

Answer 2

首先，您需要添加navigationToolBar而不是ToolBar try this Link

见这个

<android.support.design.widget.BottomNavigationView
    android:id="@+id/navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:background="@color/colorPrimary"
    app:itemIconTint="@color/nav_item_state_list"
    app:itemTextColor="@color/nav_item_state_list"
    app:menu="@menu/bottom_navigation_items"/>

如何在底部添加工具栏？
