FrameLayout.getId() on a null object

I have method loadFragment(); In which i load the DashboardFragment which is having a framelayout widget. But inside the loadFragment() i get a null pointer exception and i dont know why. I have attached the loadFragment(). please help me. Thanks!
The error is:
java.lang.NullPointerException: Attempt to invoke virtual method 'int android.widget.FrameLayout.getId()' on a null object reference.
at com.qdocs.smartschool.fragments.StudentDashboardFragment.loadFragment(StudentDashboardFragment.java:241)
loadFragment(new DashboardCalender());
private void loadFragment(Fragment fragment) {
// load fragment
FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
transaction.replace(calenderFrame.getId(), fragment);
transaction.addToBackStack(null);
transaction.commit();
}

the error is quite self-explanatory. calenderFrame is null, meaning that you never initialized it.

I have found the answer. In onCreate() of fragment my code was calling the loadFragment() method before initializing the calenderFrame.

I have a table in Mysql database with some plugs, and i added all the plugs to spinner from database.I want to retreive the data according to spinner selection.I am facing a problem that there is two records in database for plug1,when i selected plug1 its retreiving properly,when i selected plug2 in spinner its retreiving another record of plug1. I have used on-selected item position that is why it is taking position wise order.

The first textview takes up the full width of the horizontal LinearLayout so you can't see the second textview.
You can see the count by making the width of the textviews wrap_content but it probably won't match the design you're trying to achieve.

Hi i just chage the xml template as follows.

Rest Template PUT method In Android

I'm new to Android and Rest Template.I have developed a android
screen and display JSON data using Rest Template GET method on my
screen.My next step is to update some fields like edit name and add
missing things and save back to the rest Template.
public class MyPreferences extends AppCompatActivity {
TextView tv;
private Listcp = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_preferences);
Resources resources = getResources();
Log.d("Consumer pojo", "onCreate:");
new HttpRequestTask().execute();
}
private class HttpRequestTask extends AsyncTask<Void, Void, ConsumerProfile>{
#Override
protected ConsumerProfile doInBackground(Void... params) {
try {
final String url = "http://192.168.1.213:9001/consumer/local/"+LoginFragment.CONSUMEROBJECT.getId();
RestTemplate restTemplate = new RestTemplate();
ConsumerProfile cp = restTemplate.getForObject(url, ConsumerProfile.class);
return cp;
}catch (Exception e){
Log.e("MainActivity", e.getMessage(),e );
}
return null;
}
#Override
protected void onPostExecute(ConsumerProfile cp){
super.onPostExecute(cp);
Log.d("cppppppppppppppppppppp", "onPostExecute: " + cp.getId());
TextView fname=(TextView)findViewById(R.id.editfname);
TextView mname=(TextView)findViewById(R.id.editmname);
TextView lname=(TextView)findViewById(R.id.editlname);
TextView nname=(TextView)findViewById(R.id.editnname);
TextView dob=(TextView)findViewById(R.id.editdob);
TextView status=(TextView)findViewById(R.id.editstatus);
TextView homeAddress=(TextView)findViewById(R.id.edithomeAddr);
TextView workAddress=(TextView)findViewById(R.id.editworkAddr);
TextView income=(TextView)findViewById(R.id.editincome);
fname.setText(cp.getFirstName());
mname.setText(cp.getMiddleName());
lname.setText(cp.getLastName());
nname.setText(cp.getNickName());
dob.setText(cp.getDob());
status.setText(cp.getStatus());
homeAddress.setText(cp.getHomeAddress());
workAddress.setText(cp.getWorkAddress());
income.setText(cp.getIncome());
}

How to show SQLite table data into listview?

I have activities
1> mainactivity
which creates SQLite table and add stores data from edittext to mysql table
2> viewdatabse activity
which retrieves data from SQLite table and displayes in listview.
the problem is The same DATA is shown multiple time.
ex.
if i write something in edittext1 the listview will show only data of edittext1 multiple time.
here is the code of mainactivity
package com.example.androiddatabase;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.database.sqlite.SQLiteDatabase;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener {
EditText name,password,date,other;
Button save,show;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
name=(EditText)findViewById(R.id.nametext);
password=(EditText)findViewById(R.id.password);
date=(EditText)findViewById(R.id.time);
other=(EditText)findViewById(R.id.other);
save=(Button)findViewById(R.id.button1);
show=(Button)findViewById(R.id.button2);
save.setOnClickListener(this);
show.setOnClickListener(this);
SQLiteDatabase db=null;
try{
db=openOrCreateDatabase("MyIds",MODE_PRIVATE , null);
db.execSQL("create table if not exists MyInfo(names VARCHAR(30),passwords VARCHAR(10),dates INTEGER,others VARCHAR(500))");
}
catch(Exception e){
Toast.makeText(this, e.getMessage().toString(), Toast.LENGTH_LONG).show();
}
finally{
if(db.isOpen()){
db.close();
}
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v==save)
{
String n= name.getText().toString();
String p= password.getText().toString();
String d= date.getText().toString();
String o =other.getText().toString();
SQLiteDatabase db=null;
try{
db=openOrCreateDatabase("MyIds", MODE_PRIVATE, null);
db.execSQL("insert into MyInfo(names,passwords,dates,others)values('"+n+"','"+p+"','"+d+"','"+o+"')");
}
catch(Exception e)
{
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
}
finally
{
if(db.isOpen())
{
db.close();
}
}
}
else if (v==show)
{
Intent i = new Intent(this, viewdatabse.class);
startActivity(i);
}
}
}
here is the another activity which represens the listview which show data from mysql
package com.example.androiddatabase;
import java.util.ArrayList;
import java.util.HashMap;
import android.app.Activity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;
public class viewdatabse extends Activity{
ListView lv;
ArrayList<HashMap<String, String>> aa;
String name,password,date,other;
HashMap<String, String> hh;
String n,p,d,o;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.listdatabse);
lv=(ListView)findViewById(R.id.listView1);
aa = new ArrayList<HashMap<String,String>>();
SQLiteDatabase db=null;
try{
db=openOrCreateDatabase("MyIds",MODE_PRIVATE , null);
Cursor c = db.rawQuery("select * from MyInfo", null);
while(c.moveToNext())
{
hh= new HashMap<String, String>();
name=c.getString(c.getColumnIndex("names"));
hh.put(n, name);
password=c.getString(c.getColumnIndex("passwords"));
hh.put(p, password);
date=c.getString(c.getColumnIndex("dates"));
hh.put(d, date);
other=c.getString(c.getColumnIndex("others"));
hh.put(o, other);
aa.add(hh);
}
}
catch(Exception e){
Toast.makeText(this, e.getMessage().toString(), Toast.LENGTH_LONG).show();
}
finally{
if(db.isOpen()){
db.close();
}
}
String s[]={n,p,d,o};
int i[]={R.id.textView1,R.id.textView2,R.id.textView3,R.id.textView4};
SimpleAdapter sa = new SimpleAdapter(this, aa, R.layout.customlist, s, i);
lv.setAdapter(sa);
}
}
here is the mainactivity xml file which has 4 edittext to take user input
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

android:layout_width="match_parent"
android:layout_height="wrap_content"

</LinearLayout>
here is xml for view database activity which has listview to show data.
<?xml version="1.0" encoding="utf-8"?>
