Accelerometer Sensor

Using Accelerometer in Android application

Step 1. Create a new Project.

Step 2. Go to the design view and select the Text Fields section in the Palette and locate Plain Text

Step 3. Drag and drop from the Form Widgets section into the layout and design a GUI as given below.

Step 4. Switch to the Text view, XML layout file and verify that the file looks similar to the following listing.

<?xml version="1.0" encoding="utf-8"?>

<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="idamithw.mysensor.MainActivity">

          <TextView

          android:layout_width="wrap_content"

          android:layout_height="wrap_content"

          android:textAppearance="?android:attr/textAppearanceLarge"

          android:text="X       :"

          android:layout_marginTop="79dp"

          android:textSize="50dp"

          android:layout_alignParentTop="true"

          android:layout_alignParentStart="true"

          android:layout_marginStart="109dp"

          android:id="@+id/textView2" />

          <TextView

          android:layout_width="wrap_content"

          android:layout_height="wrap_content"

          android:textAppearance="?android:attr/textAppearanceLarge"

          android:text="Y        :"

          android:id="@+id/textView"

          android:textSize="50dp"

          android:layout_centerVertical="true"

          android:layout_alignStart="@+id/textView2" />

          <TextView

          android:layout_width="wrap_content"

          android:layout_height="wrap_content"

          android:textAppearance="?android:attr/textAppearanceLarge"

          android:text="Z       :"

          android:id="@+id/textView3"

          android:layout_marginBottom="74dp"

          android:textSize="50dp"

          android:layout_alignParentBottom="true"

          android:layout_alignStart="@+id/textView" />

          <TextView

          android:layout_width="wrap_content"

          android:layout_height="wrap_content"

          android:textAppearance="?android:attr/textAppearanceLarge"

          android:text="0"

           android:id="@+id/xcord"

          android:textSize="50dp"

          android:layout_alignTop="@+id/textView2"

          android:layout_alignParentEnd="true"

          android:layout_marginEnd="90dp" />

          <TextView

          android:layout_width="wrap_content"

          android:layout_height="wrap_content"

          android:textAppearance="?android:attr/textAppearanceLarge"

          android:text="0"

          android:id="@+id/ycord"

          android:textSize="50dp"

          android:layout_alignTop="@+id/textView"

           android:layout_alignStart="@+id/xcord" />

          <TextView

          android:layout_width="wrap_content"

          android:layout_height="wrap_content"

          android:textAppearance="?android:attr/textAppearanceLarge"

          android:text="0"

          android:id="@+id/zcord"

          android:textSize="50dp"

          android:layout_alignTop="@+id/textView3"

          android:layout_alignStart="@+id/ycord" />

</RelativeLayout>

 

Step 5.   Change your Activity class by adding the information on the view.

package idamithw.mysensor;

import android.hardware.Sensor;

import android.hardware.SensorEvent;

import android.hardware.SensorEventListener;

import android.hardware.SensorManager;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.widget.TextView;

public class MainActivity extends AppCompatActivity implements SensorEventListener {

          private TextView xcord,ycord,zcord;

          private Sensor mysensor;

          private SensorManager SenMan;

         

@Override

          protected void onCreate(Bundle savedInstanceState) {

          super.onCreate(savedInstanceState);

          setContentView(R.layout.activity_main);

          SenMan=(SensorManager)getSystemService(SENSOR_SERVICE);

          mysensor= SenMan.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);

          SenMan.registerListener(this,mysensor,SensorManager.SENSOR_DELAY_NORMAL);

          xcord=(TextView)findViewById(R.id.xcord);

          ycord=(TextView)findViewById(R.id.ycord);

          zcord=(TextView)findViewById(R.id.zcord);

          }

          @Override

          public void onSensorChanged(SensorEvent sensorEvent) {

          xcord.setText(" "+sensorEvent.values[0]);

          ycord.setText(" "+sensorEvent.values[1]);

          zcord.setText(" "+sensorEvent.values[2] );

          }

          @Override

          public void onAccuracyChanged(Sensor sensor, int i) {

          }

}

Step 6.   Run your application on an Android device
