如何让 Android SlidingDrawer 从左侧滑出？

How to make an Android SlidingDrawer slide out from the left?

提问by Vidar Vestnes

I'm using a slidingDrawerin my application that has its handler placed at the bottom when in portrait mode. When the user switches to landscape mode (widescreen) I would like to have the handler located on the left. When I change the orientation from vertical to horizontal, the handler is placed on the right.

我slidingDrawer在我的应用程序中使用了一个，在纵向模式下，它的处理程序位于底部。当用户切换到横向模式（宽屏）时，我希望处理程序位于左侧。当我将方向从垂直更改为水平时，处理程序位于右侧。

I have defined my layout XML like this:

我已经像这样定义了我的布局 XML：

<SlidingDrawer
    android:id="@+id/l_drawer"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:handle="@+id/l_handle"
    android:content="@+id/l_content"
    android:orientation="horizontal"
    android:layout_gravity="left"
    >

Anyone have an idea for how to make it slide from left to right ?

任何人都知道如何让它从左向右滑动？

I don't think you can, other than perhaps by grabbing the SlidingDrawersource code, making changes to it, and using your modified version. You similarly cannot make a SlidingDrawerthat descends from the top.

我不认为你可以，除了可能通过获取SlidingDrawer源代码，对其进行更改并使用修改后的版本。你同样不能制作一个SlidingDrawer从顶部下降的。

I've found a simple way to do that. All you have to do is to set the rotation of 180o for the slidingDrawer, the content and the handle. You can similarly make a SlidingDrawer that descends from the top, like I did here.

我找到了一个简单的方法来做到这一点。你所要做的就是为slidingDrawer、内容和手柄设置180o的旋转。您可以类似地制作一个从顶部下降的 SlidingDrawer，就像我在这里所做的那样。

Look at my examples here, first from right to left, to be able to see the differences.

看看我这里的例子，首先从右到左，以便能够看到差异。

<SlidingDrawer xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/slidingDrawer"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="center_horizontal"
    android:handle="@+id/handle"
    android:content="@+id/content">
    <ImageView android:id="@+id/handle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />
    <ImageView android:id="@+id/content"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#FF0000"
        android:src="@drawable/ic_launcher" />
</SlidingDrawer>

Now look what I changed to make it sliding out from the left.

现在看看我改变了什么让它从左边滑出来。

<SlidingDrawer xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/slidingDrawer"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="center_horizontal"
    android:handle="@+id/handle"
    android:content="@+id/content"
    android:rotation="180">
    <LinearLayout android:id="@+id/handle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <ImageView android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher"
            android:rotation="180" />
    </LinearLayout>
    <ImageView android:id="@+id/content"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#FF0000"
        android:src="@drawable/ic_launcher"
        android:rotation="180" />
</SlidingDrawer>

Note that I also created a LinearLayout to set as handle, and didn't change it's rotation, but I changed the rotation of it's child. This was to prevent a small issue I had, but everything is working fine and it's simple.

请注意，我还创建了一个 LinearLayout 来设置为句柄，并没有改变它的旋转，但是我改变了它的子级的旋转。这是为了防止我遇到的一个小问题，但一切正常，而且很简单。

I have rewritten a class to that and made it part of my open source library. It took me almost a week to get it right. Please check out my SlidingTrayin Aniqroidopen source library for Android.

我为此重写了一个类，并将其作为我的开源库的一部分。我花了将近一周的时间才把它弄好。请在Android 的Aniqroid开源库中查看我的SlidingTray。

You can use the code posted in this answer: Android SlidingDrawer from top?

您可以使用此答案中发布的代码：Android SlidingDrawer from top?

The provided solution features setting the orientation of the Slidingdrawer in xml also it's simple requiring only 1 class and some additions in attrs.xml and stable since it's derived from Androids Slidingdrawer from SDK. I also discuss why I didn't choose other popular libs/solutions found on the internet/SO.

提供的解决方案的特点是在 xml 中设置 Slidingdrawer 的方向，而且它很简单，只需要 1 个类和 attrs.xml 中的一些添加项，并且稳定，因为它源自 SDK 的 Androids Slidingdrawer。我还讨论了为什么我没有选择在 Internet/SO 上找到的其他流行的库/解决方案。
