Pedometer in fragment

I am trying to use the pedometer sensor in a fragment to count the number of steps that has been taken since the device last rebooted.
I can get the pedometer working in an Activity but cannot seem to get it working in the fragment. I am new to using fragments so it's probably very simple what I am doing wrong.
My class is below:
import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
import static com.example.application.placepicker.R.id.count;
public class Tab3 extends Fragment implements SensorEventListener {
private SensorManager sensorManager;
private TextView textView;
boolean activityRunning;
private Button buttonReturn;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab3, container, false);
return rootView;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
count = (TextView) getActivity().findViewById(count); **error
sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); **error
}
#Override
public void onResume() {
super.onResume();
activityRunning = true;
Sensor countSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER);
if (countSensor != null) {
sensorManager.registerListener(this, countSensor, SensorManager.SENSOR_DELAY_UI);
} else {
Toast.makeText(this, "Count sensor not available!", Toast.LENGTH_LONG).show(); **error
}
}
#Override
public void onPause() {
super.onPause();
activityRunning = false;
}
#Override
public void onSensorChanged(SensorEvent event) {
if (activityRunning) {
count.setText(String.valueOf(event.values[0])); **error
}
}
#Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
}
My XML file to accompany this is:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

You have no member variable for count
private SensorManager sensorManager;
private TextView textView;
boolean activityRunning;
private Button buttonReturn;
are examples of member variables in your fragment class
count = (TextView) getActivity().findViewById(count);
is setting a TextView to an unknown reference, please initialise count properly i.e.
TextView count = (TextView) getActivity().findViewById(count);
as a function member or:
private TextView count;
with the other class member variables
you will then need to call
sensorManager = (SensorManager) getActivity().getSystemService(Context.SENSOR_SERVICE)
as a fragment has no reference to the getSystemService method by itself, so it needs to go through it's holding activity

as well i know
you should change
count = (TextView) getActivity().findViewById(count);
to
count = (TextView)getView().findViewById(R.id.count);
cause you have to define view , don't call activity.

Add text box to wearable screen - beginner

Here is the code I'm using to read the heart rate from a wearable :

import android.support.wearable.activity.WearableActivity;
import android.util.Log;

import android.support.wearable.view.BoxInsetLayout.*;
public class MainActivity extends WearableActivity implements SensorEventListener {
private static final String TAG = "MainActivity";
private TextView mTextViewHeart;
SensorManager mSensorManager;
Sensor mHeartRateSensor;
SensorEventListener sensorEventListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
mTextViewHeart = new TextView(this);
mTextViewHeart.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
mTextViewHeart.setText("heart rate ");
mSensorManager = ((SensorManager) getSystemService(SENSOR_SERVICE));
mHeartRateSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_HEART_RATE);
// mSensorManager.registerListener(this, mHeartRateSensor, SensorManager.SENSOR_DELAY_NORMAL);
Log.i(TAG, "LISTENER REGISTERED.");
mTextViewHeart.setText("Something here");
mSensorManager.registerListener(this, mHeartRateSensor, mSensorManager.SENSOR_DELAY_FASTEST);
// mSensorManager.registerListener(sensorEventListener, mHeartRateSensor, mSensorManager.SENSOR_DELAY_FASTEST);
}
public void onResume(){
super.onResume();
}
public void onAccuracyChanged(Sensor sensor, int accuracy) {
Log.d(TAG, "onAccuracyChanged - accuracy: " + accuracy);
}
public void onSensorChanged(SensorEvent event) {
if (event.sensor.getType() == Sensor.TYPE_HEART_RATE) {
String msg = "" + (int)event.values[0];
mTextViewHeart.setText(msg);
Log.d(TAG, msg);
}
else
Log.d(TAG, "Unknown sensor type");
}
}
main_activity.xml :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

The sensor functionality seems fine. The text boxes are not being displayed on screen, instead I just receive a blank screen. How to add mTextViewHeart to the screen programmatically ? Or is required that I add it via main_activity.xml ?

I've updated with Pavneet Singh answer but blank screen displayed.
Maybe should configure all UI via XML ?
Update2 :
Updating to use linearlayout does not have an impact :
<?xml version="1.0" encoding="utf-8"?>

Adding an edittext field also does not display :
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="121dp"
android:ems="10"
android:text="test"
/>
Could the issue be something fundamental ?

This screen layout displays :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"

<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Click me to another screen" />
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="I'm screen 1 (main.xml)"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

Delay in android step counter

I am developing an android step counter that starts counting when i press a button and stops when i press the button again. The problem is that the counter always misses the first few steps i am using the step counter sensor introduced in android kitkat 4.4. I also tried the step detector sensor but had the same results.
I tried changing the delay when registering the sensor to fastest, game, normal, and I even tried to set the delay to 0 but nothing worked
Is there a way i can fix this?
this is a simple app that shows my problem

Edited: Added code snippets

I realized that using the predefined stepCounter sensor for small number of steps, like what i wanted, isn't the best option and implementing a counter using accelerometer would be a lot better; however it won't be recommended for building fitness apps or any app that require constant step counting for a long time because the delay in the stepcounting sensor is to neglect the false positives.
so this is my implementation of the stepcounter using accelerometer

Adjusting the threshold sets the sensitivity of the sensor :)

As I mentioned, your problem is this call: getString(fare), which is attempting to retrieve a String resource with an id the value of fare. Judging from your code, I'm assuming that you're simply trying to display the String value of fare in a TextView, in which case change that call as follows:
String sfare = String.valueOf(fare);

First you need to create main.xml in layout folder in res directory. This is the main layout which is loading in your Activity , take two TextView inside main.xml with id named as lat and longi. main.xml is given below.
<?xml version="1.0" encoding="utf-8"?>
<TextView
android:id="#+id/lat"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="195dp"
android:text="Lattitude" />
<TextView
android:id="#+id/longi"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/textView2"
android:layout_alignParentTop="true"
android:layout_marginTop="82dp"
android:text="Longitude" />
