How can I get the current screen orientation in Android?
In some situation, we need to find an android activity orientation. This example demonstrates how to integrate Android Login and registration form.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version = "1.0" encoding = "utf-8"?> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:id = "@+id/parent" xmlns:tools = "http://schemas.android.com/tools" android:layout_width = "match_parent" android:layout_height = "match_parent" tools:context = ".MainActivity" android:gravity = "center" android:orientation = "vertical"> <TextView android:id = "@+id/text" android:textSize = "28sp" android:textAlignment = "center" android:layout_width = "match_parent" android:layout_height = "wrap_content" /> </LinearLayout>
In the above code, we have taken a text view. According to screen orientation, text view going to update the text.
Step 3 − Add the following code to src/MainActivity.java
package com.example.andy.myapplication;
import android.content.res.Configuration;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
int view = R.layout.activity_main;
TextView textview;
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(view);
textview = findViewById(R.id.text);
int orientation = this.getResources().getConfiguration().orientation;
if (orientation = = Configuration.ORIENTATION_PORTRAIT) {
textview.setText("Portrait mode");
} else {
textview.setText("landscape mode");
}
}
}In the above code, we have taken orientation as integer and comparing with configuring orientation as shown below -
int orientation = this.getResources().getConfiguration().orientation;
if (orientation = = Configuration.ORIENTATION_PORTRAIT) {
textview.setText("Portrait mode");
} else {
textview.setText("landscape mode");
}Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run 
icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
When user keeps mobile as portrait mode, it will show the result as shown above. Now turn the device to landscape mode, it will show the result as shown below -
