How to show SQLite table data into listview?

How to show SQLite table data into listview? - android

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

Try this method in DB class,
public Cursor getAllNames(){
sqLiteDatabase = helper.getReadableDatabase();
return sqLiteDatabase.query(TBNAME,new String[] {NAME,E_Mail,PHONE},null,null,null,null,null);
}

PopUp Window not updating database - Android

I'm trying to create a kind of game using Android Studio. Till now I have done a gridview wich shows players stored in a database. I have had some problems with gridView.setOnItemClickListener, I have had to do it by putting the code into gridView's Adparter.class so if you know how I can do that into gridView's activity please tell me.
My problem now is that when you click on a player a popup window appears in which you could change the player's name or his genre. When you click on Confirm's button the database will automatically been updated, but it doesn't works. I have try to do it step by step by using Toast in order to know if it run that part or not, the problem could be the context, but maybe I'm crazy.
I left you some pics and the code related to it.

From what I´ve seen in your code is, that you try to get the id from an intent in your PopUp window class. You have made one thing wrong:
Intent i = getIntent();
i.getIntExtra("Id", id);
it must be:
Intent i = getIntent();
id = i.getIntExtra("Id", id); //forgott id = here
and you should give a default value to id for example id=-1 . The problem is, by updating your database, you give a non value integer and so it is not possible to update your table.

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());
}
}This Screen is for Get Method
This is what I did Up to Now.
This code is for Get method.
It'll display The screen like in image.

A ListView must have the layout_height attribute not setted to wrap_content. A ListView content height is dynamic, since you don't always have the same number of cells. Thus, you need to match the parent size or have a fixed height.

Change color of items in spinner

I want to change the color of items in spinner to say 3 different colors and all the items should be added dynamically.
I am adding items in the spinner through list.
Suppose i have 2 lists and i want to merge both list items in single spinner item but
both should be of different colors.
My xml file is :
<?xml version="1.0" encoding="utf-8"?>

android:text="abcd"
android:textColor="#android:color/white"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/tvMaterial"
android:layout_width="wrap_content"

You can try SpannableString for coloring your text http://developer.android.com/reference/android/text/SpannableString.html
