So here is the complete step by step tutorial for Check/Get battery status in android programmatically.

Following 5 types of status are available in android devices :

How to Check/Get battery status in android programmatically.

Code for MainActivity.java file.

 package com.batterystatus_android_examples.com;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.BatteryManager;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends Activity {

 TextView textview;
 Button button;
 IntentFilter intentfilter;
 int deviceStatus;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 
 button = (Button)findViewById(R.id.button1);
 textview = (TextView)findViewById(R.id.textView1);
 
 intentfilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
 
 button.setOnClickListener(new View.OnClickListener() {
 
 @Override
 public void onClick(View v) {
 // TODO Auto-generated method stub
 
 MainActivity.this.registerReceiver(broadcastreceiver,intentfilter);
 
 }
 });
 
 }
 
 private BroadcastReceiver broadcastreceiver = new BroadcastReceiver() {
 @Override
 public void onReceive(Context context, Intent intent) {
 
 deviceStatus = intent.getIntExtra(BatteryManager.EXTRA_STATUS,-1);
 
 if(deviceStatus == BatteryManager.BATTERY_STATUS_CHARGING){
 
 textview.setText("Battery Status = Charging ");
 
 }
 
 if(deviceStatus == BatteryManager.BATTERY_STATUS_DISCHARGING){
 
 textview.setText("Battery Status = Discharging ");
 
 }
 
 if (deviceStatus == BatteryManager.BATTERY_STATUS_FULL){
 
 textview.setText("Battery Status = Battery Full ");
 
 }
 
 if(deviceStatus == BatteryManager.BATTERY_STATUS_UNKNOWN){
 
 textview.setText("Battery Status = Unknown ");
 }
 
 
 if (deviceStatus == BatteryManager.BATTERY_STATUS_NOT_CHARGING){
 
 textview.setText("Battery Status = Not Charging ");
 
 }

 }
 };
 

}

Code for activity_main.xml layout 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:paddingLeft="@dimen/activity_horizontal_margin"
 android:paddingRight="@dimen/activity_horizontal_margin"
 android:paddingTop="@dimen/activity_vertical_margin"
 tools:context="com.batterystatus_android_examples.com.MainActivity" >

 <TextView
 android:id="@+id/textView1"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_centerHorizontal="true"
 android:layout_centerVertical="true"
 android:text="Status"
 android:textAppearance="?android:attr/textAppearanceLarge" />

 <Button
 android:id="@+id/button1"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_below="@+id/textView1"
 android:layout_centerHorizontal="true"
 android:layout_marginTop="16dp"
