Check Android ScreenOrientation At Runtime

In this Post we will see how to check android screen-orientation at Run-time , in the previous series i have covered how to fixed the Activity (Screen) to any particular orientation (i.e either Landscape or Portrait ) .

1. Firstly we will get the Resources object of application and.
2. Then we will get the configuration object that is in effect with resource object  .
3. The configuration class contains a constants whose values may be one of ORIENTATION_LANDSCAPE, ORIENTATION_PORTRAIT. using this constant we will get to know what is the current orientation.

Resources res = getResources();
Configuration conf = res.getConfiguration();

int flag = conf.orientation;

1. XML Layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="50dp"
        android:text=""
        android:textSize="25sp" />

</LinearLayout>

2. Activity

package com.pavan.screenorientationdemo;

import android.app.Activity;
import android.content.res.Configuration;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends Activity {

 TextView display;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  display = (TextView) findViewById(R.id.textView1);

  Resources res = getResources();
  Configuration conf = res.getConfiguration();

  int flag = conf.orientation;

  if (flag == Configuration.ORIENTATION_PORTRAIT) {
   display.setText("In PORTRAIT MODE");
  } else if (flag == Configuration.ORIENTATION_LANDSCAPE) {
   display.setText("In LANDSCAPE MODE");
  }

 }

}
