Java Android 5.0如何在纵向模式下保持屏幕方向？

我需要将屏幕保持在纵向模式。为此，我在清单文件中使用这一行

android:screenOrientation="portrait"

这是我的档案

我试过一些，但它仍然旋转

我做错了什么

能否添加

android:configChanges=“orientation | keyboardHidden”

---

将方向锁定为其当前旋转（无论是什么）。在API级别18中添加

android:screenOrientation="locked"

---

在您的清单文件中，在您的主要活动后粘贴到下面的行

android:screenOrientation="portrait"

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

或者在编码后将setContentView（）粘贴到第行下方

android:screenOrientation="portrait"

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

---

在主活动后的清单文件中，粘贴到第行下方

android:screenOrientation="portrait"

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

java通过setContentView（）粘贴到第行下方

android:screenOrientation="portrait"

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

---

android:screenOrientation=“locked”将此添加到manifest@MalithLakshan不我试过了，但是没有成功。。。事实上，我已经添加了整个清单文件。你能检查一下你的主题样式，看看里面是否有任何屏幕方向吗？@TilakMadichetti No。。。我需要为所有应用程序保持肖像模式。我试过android:screenOrientation=“Picture”，但根据我的问题，它不起作用。你是什么意思？根据我的问题，我注意到我已经做了，但它不起作用。。。你还有别的想法吗？没有。。。我试过了，但是没有成功。。。事实上，我已经添加了整个清单文件，根据我所说的问题，android:screenOrientation=“肖像”不起作用，第二个我需要为所有应用程序保留屏幕肖像模式，而不是执行活动…不（（它仍然可以旋转）
