In this android example we will learn how to detect device orientation programmatically. When device rotate activity onConfigurationChanged will trigger and we can fetch the current orientation of the device using Configuration instance.
let get started
1. Create Android application
2. Add below code in activity class
package rrtutors.com.androidtopactivity
import android.content.pm.ActivityInfo
import android.content.res.Configuration
import android.os.Build
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.DisplayMetrics
import android.view.View
import android.widget.TextView
import android.widget.Toast
import org.w3c.dom.Text
class SDkVersion : AppCompatActivity() {
lateinit var txt_info: TextView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_sdk_version)
txt_info=findViewById(R.id.txt_info)
}
override fun onConfigurationChanged(newConfig: Configuration) {
super.onConfigurationChanged(newConfig)
if(newConfig.orientation==Configuration.ORIENTATION_LANDSCAPE)
Toast.makeText(applicationContext,"Orientation Landscape",Toast.LENGTH_SHORT).show()
else Toast.makeText(applicationContext,"Orientation Portrait",Toast.LENGTH_SHORT).show()
}
}
|
3. Now run application and rotate the device. Each rotation activity will called onConfigurationChanged method and will display the current orientation as toast message
