如何更改 NavigationView 中菜单项的图标方向？

Question

您好，我正在使用 Android NavigationView。我想将图标方向更改为 RTL 而不是 LTR，如下所示：

我该怎么做？

Answer 1

您可以像我一样在导航视图中使用列表视图。这样做的好处是您可以更好地控制：

<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:headerLayout="@layout/header"
    >
    <ListView
        android:id="@+id/navigationmenu"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="192dp"
        android:background="@android:color/white">
    </ListView>

</android.support.design.widget.NavigationView>

导航项应该是这样的：

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

    android:background="@color/cardview_dark_background"
    >
    <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_height="wrap_content"
        android:src="@drawable/viewlist"
        />
    <TextView
        android:id="@+id/tvlstName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20dp"
        android:layout_marginRight="30dp"
        android:textColor="@color/colorPrimary"

        />
</RelativeLayout>

和像这样的 navcustomadapter：

package com.example.android.dezcook;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

/**
 * Created by Android on 6/4/2016.
 */
public class navCustomAdapter extends BaseAdapter {

    String[] result;
    Context context;
    int[] imageId;
    private static LayoutInflater inflater=null;
    public navCustomAdapter(MainActivity mainActivity,String[] prgmNameList,int[] prgImages)
    {
        result=prgmNameList;
        imageId=prgImages;
        context =mainActivity;
        inflater =(LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);

    }
    @Override
    public int getCount()
    {
        return result.length;
    }
    @Override
    public Object getItem(int position)
    {
        return position;
    }
    @Override
    public long getItemId(int position)
    {
        return position;
    }
    public class Holder
    {
        TextView tv;
        ImageView img;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent)
    {
        Holder holder=new Holder();
        View rowView;
        rowView=inflater.inflate(R.layout.navitem,null);
        holder.tv=(TextView)rowView.findViewById(R.id.tvlstName);
        holder.img=(ImageView)rowView.findViewById(R.id.img);
        holder.tv.setText(result[position]);
        holder.img.setImageResource(imageId[position]);
        rowView.setOnClickListener(new View.OnClickListener() {
                                       @Override
                                       public void onClick(View v) {
                                           Toast.makeText(context,"you Clicked "+result[position],Toast.LENGTH_LONG).show();
                                       }
                                   }


        );
        return rowView;
    }

}

最后在主活动中这样调用它：

 ListView lv=(ListView)findViewById(R.id.navigationmenu);
        lv.setAdapter(new navCustomAdapter(this,navItem,prgmImages)

想办法！

尝试将这些属性添加到布局文件中的NavigationView。

 android:layoutDirection="rtl"
 android:textDirection="rtl"

注意：它似乎适用于 API 17 及更高版本

我遇到了这个问题。我的应用是“ltr”，我想在“rtf”模式下查看抽屉。 我的解决方案： 在导航视图中我清除了：

• app:menu="@menu/drawer_menu"
• app:headerLayout="@layout/drawer_nav_header"

并替换：

• 包括 layout="@layout/drawer_nav_header"/>

• 包括 layout="@layout/ly_custom_menu_item"/>

  <include layout="@layout/fragment_map" />
  <FrameLayout
      android:id="@+id/content_frame"
      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="right"
      android:background="@color/white"
      android:fitsSystemWindows="true">
  
      <!--app:menu="@menu/drawer_menu"
      app:headerLayout="@layout/drawer_nav_header"-->
  
      <LinearLayout
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:orientation="vertical">
  
          <include layout="@layout/drawer_nav_header"/>
          <include layout="@layout/ly_custom_menu_item"/>
  
       </LinearLayout>
  
  </android.support.design.widget.NavigationView>
  

ly_custom_menu_item.xml：

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

            app:layout_constraintEnd_toEndOf="parent"/>
   </LinearLayout>

   </LinearLayout>

 </ScrollView>

尝试设置您的导航抽屉项目布局重力。示例：

android:gravity="right"
