有人可以告诉我如何将我的应用程序锁定到纵向模式?是清单文件中的简单配置吗?
解决方案
Yes. Add android:screenOrientation="portrait"
to the manifest under your main activity.
<activity android:name=".yourActivity" android:screenOrientation="portrait"... />
其他提示
Yes! It's an attribute of the activity tag:
<activity android:name=".yourActivity" android:screenOrientation="portrait" ... />
Also, you may have to add the following to your activity element:
android:configChanges="keyboardHidden"
That way, the OS won't change the orientation when the user opens a sliding keyboard.
None of these answers worked on my system but I did find the following worked perfectly for a simple app that I developed:
Within MainActivity.java add:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
to onCreate ()
This is mine:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
I know that it is not (always) best practice locking orientation, but in special circumstances it is valid and I only want this temporarily while I continue developing.
