How to fix layout orientation to vertical?

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"

Use setRequestedOrientation() as shown:

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

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"
