Create Sensor Effect In Android

1] Write a code in JAVA File:
    
package com.example.sensordemo;
import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.ImageView;

public class MainActivity extends Activity implements SensorEventListener {
     private SensorManager mSensorManager;
     private Sensor mSensor;
     ImageView iv;
   
     @Override
  protected void onCreate(Bundle savedInstanceState) {
      // TODO Auto-generated method stub
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
      mSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);
      iv = (ImageView) findViewById(R.id.imageView1);
     }
   
     protected void onResume() {
      super.onResume();
      mSensorManager.registerListener(this, mSensor,
        SensorManager.SENSOR_DELAY_NORMAL);
     }
   
     protected void onPause() {
      super.onPause();
      mSensorManager.unregisterListener(this);
     }
   
     public void onAccuracyChanged(Sensor sensor, int accuracy) {
     }
   
     public void onSensorChanged(SensorEvent event) {
      if (event.values[0] == 0) {
     iv.setImageResource(R.drawable.a);
      } else {
       iv.setImageResource(R.drawable.ic_launcher);
      }
    }  
}

2] Write a code in main.xml File:
   

   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="41dp"
        android:layout_marginTop="51dp"
        android:src="@drawable/a" />

</RelativeLayout>


Note:-You Must Check This Proramm In Real Device Which have sensor.
