How to fix layout orientation to vertical?

Question

How to fix layout orientation to portrait and do not allow changing from portrait to landscape during run time?

Answer 1

Use setRequestedOrientation() as shown:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
setContentView(R.layout.main);

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Answer 2

In your AndroidMainfest.xml just write this in your activity you declare,

If you want in layout vertical than use

android:screenOrientation="portrait"

If you want in layout landscape than use

android:screenOrientation="landscape"

Answer 3

If you want to freeze orientation at runtime, then you you can implement this:

Android: Temporarily disable orientation changes in an Activity

I use a similar approach and it works perfectly.

Answer 4

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

before

setContentView(R.layout.main);

Answer 5

In your AndroidMainfest.xml file find the tags of the activities you wish to lock to a given rotation, and add this attribute:

android:screenOrientation="portrait"

Answer 6

in your activity parameters in Manifest File

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.statepermit" android:versionCode="1" android:versionName="1.0">
    <application android:icon="@drawable/stateheader" android:label="@string/app_name">
        <activity android:name=".statepermit" android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar" android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
    <uses-sdk android:minSdkVersion="7" />

</manifest>

android:screenOrientation="portrait"
