Best practice to place menu Icons on the left side of the navigation drawer in Persian,Hebrew devices?

问题

我正在尝试创建一个从右侧打开的导航抽屉(我使用LAYOUT_GRAVITY="END"成功实现了这一点)。现在我希望所有菜单项都从右侧开始,它们的图标也在右侧。

为了实现这一点,我在清单中添加了(SUPPORTSRTL="TRUE"),这也解决了问题。但问题在于:

  • 如果设备的语言设置为英语,一切都能正常工作。
  • 但如果设备的语言设置为波斯语(这是一种RTL语言),那么应用程序中的其他所有内容都会变成从右到左。这意味着我放在右侧的任何东西都会移动到左侧,而设置为左侧的任何东西都会移动到右侧。我甚至尝试使用"start"和"end"代替"right"和"left",但问题没有解决。

为了解决这个问题,我不得不在每个活动的布局根元素上设置(LAYOUTDIRECTION="LTR")。这解决了问题,现在一切都处于我期望的位置,但这似乎不是一个可持续的解决方案,因为我将来可能会在应用程序中添加此代码行。请问这是否是最佳方法?

我发现其他关于相同主题的问题,但没有一个得到合适的答案。

I am trying to have a navigation drawer that opens from the right. ( i managed to do that using LAYOUT_GRAVITY="END").
Now I want all the menu items to start from the right and also their Icons on the right too.

To do that I added (SUPPORTSRTL="TRUE") to the manifest and that also solved the problem. But here is the problem:

  • if the device's language is set to English, everything works perfectly.
  • But if the device's language is set to Persian(which is a RTL language) then everything else in the app will be right to left. That means what ever I put in the right goes to left and what ever that is set to the left goes to the right. I even tried using "start" and "end" instead of "right" and "left" but that didn't solve the problem.

To solve that I had to set the (LAYOUTDIRECTION="LTR") to the root element of layouts on every one of my actitives. That solved the problem and now everything is in the position I desired, however this doesn't seem like a sustainable solution to add this line of code to root element of each activity I will ever add to my app.
Can you please tell me if this is the best way to do it or not?

I found other questions with the same topic with no accepted proper answers.

这行代码应该解决了您的问题

ViewCompat.setLayoutDirection(drawer, ViewCompat.LAYOUT_DIRECTION_RTL);

drawer 是对您的 DrawerLayout 的引用。

另一种强制将活动布局设置为从右到左(RTL)的方法是使用样式 XML。这是我会这样做的方式:

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

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <!-- 自定义您的主题内容。 -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="ShaliRTL" parent="AppTheme">
    <item name="android:layoutDirection">rtl</item>
</style>

</resources>

然后,在 Android 清单文件中将这个新样式(ShaliRTL)应用于您的特定活动:

<activity
    android:name=".YourActivity"
    android:label="@string/title_activity_settings"
    android:theme="@style/ShaliRTL"
    android:screenOrientation="fullSensor" />

祝您好运。

英文:

this line of code should solve your problem

    ViewCompat.setLayoutDirection(drawer, ViewCompat.LAYOUT_DIRECTION_RTL);

drawer is a reference to your DrawerLayout.

an other way to force RTL layout to activities is using styles xml. this is how i whould do it:

&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
&lt;resources&gt;

&lt;style name=&quot;AppTheme&quot; parent=&quot;Theme.MaterialComponents.Light.NoActionBar&quot;&gt;
    &lt;!-- Customize your theme here. --&gt;
    &lt;item name=&quot;colorPrimary&quot;&gt;@color/colorPrimary&lt;/item&gt;
    &lt;item name=&quot;colorPrimaryDark&quot;&gt;@color/colorPrimaryDark&lt;/item&gt;
    &lt;item name=&quot;colorAccent&quot;&gt;@color/colorAccent&lt;/item&gt;

&lt;/style&gt;

&lt;style name=&quot;ShaliRTL&quot; parent=&quot;AppTheme&quot;&gt;
    &lt;item name=&quot;android:layoutDirection&quot;&gt;rtl&lt;/item&gt;
&lt;/style&gt;

&lt;/resources&gt;

then in android manifest apply this new style (ShaliRTL) to your specific activity:

        &lt;activity
        android:name=&quot;.YourActivity&quot;
        android:label=&quot;@string/title_activity_settings&quot;
        android:theme=&quot;@style/ShaliRTL&quot;
        android:screenOrientation=&quot;fullSensor&quot; /&gt;

good luck.
