安卓：允许纵向和横向的平板电脑，但手机强迫肖像？ [英] Android: allow portrait and landscape for tablets, but force portrait on phone?

问题描述

我想平板电脑能在纵向和横向（sw600dp或更高）显示，但手机只限于肖像。我找不到任何方法来有条件地选择一个方向。有什么建议？

I would like tablets to be able to display in portrait and landscape (sw600dp or greater), but phones to be restricted to portrait only. I can't find any way to conditionally choose an orientation. Any suggestions?

推荐答案

下面是一个使用的资源和大小预选赛的。

Here's a good way using resources and size qualifiers.

放入RES /值bools.xml或任何这种布尔资源（文件名不事这里）：

Put this bool resource in res/values as bools.xml or whatever (file names don't matter here):

    <?xml version="1.0" encoding="utf-8"?>
    <resources>
        <bool name="portrait_only">true</bool>
    </resources>

将这个之一RES /价值观sw600dp和RES /价值观XLARGE：

Put this one in res/values-sw600dp and res/values-xlarge:

    <?xml version="1.0" encoding="utf-8"?>
    <resources>
        <bool name="portrait_only">false</bool>
    </resources>

然后，在你的活动的onCreate方法，你可以这样做：

Then, in the onCreate method of your Activities you can do this:

    if(getResources().getBoolean(R.bool.portrait_only)){
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }

设备是超过600 DP的最小宽度方向，或X大的pre-的Andr​​oid 3.2设备（平板电脑，主要）会像正常的based~~V传感器和用户锁定旋转等。其他一切（手机，pretty的多）将是唯一的肖像。

Devices that are more than 600 dp in the smallest width direction, or x-large on pre-Android 3.2 devices (tablets, basically) will behave like normal, based on sensor and user-locked rotation, etc. Everything else (phones, pretty much) will be portrait only.
