database id's are interchanged android sqlite

Good Day everyone. I have this code and i face problem in deleting. For example, my list of names are Junko, Gemina and Fukar. If i view each, they show same details. Now, if I delete any of them, ex. I delete Fukar, it will be deleted successfully but when I click on Gemina, the detail that appears is of Junko. If i click Junko, it says "Unfortunately the app stopped working". If I add new Name, ex. Nimrod, It will add successfully, but when i view Nimrod, the detail of Gemina will appear. And if i add another name, Vourin, the data of Gemina will appear its like their ids are interchanged and I think the error is in the delete part. I appreciate any comment. Thanks.

I added Person.java and edited MainActivity.java and DBHelper.java

This is your problem:
int id_to_search = position + 1;
You are assuming that the IDs and the positions are in sync. This is only true as long as you do not remove any entries. Instead of using the position to reference an entry, you have to use the ID, as that's immutable.
When you pull the entries from your database, you need to pull the name and the ID, and keep that data in your adapter, so you can reference an entry by its ID.
Some code below (just a skeleton):
1) Create a model for your data
public class Person {
// consider making private and adding accessors
public String name;
public long id;
}
2) when you pull your data, pull the name and the ID (you may expand the Person class and this function to pull additional data):
public List<Person> getAllStudentContacts(){
List<Person> arraylist= new ArrayList<>();
SQLiteDatabase db=this.getReadableDatabase();
Cursor cursor=db.rawQuery("Select * from mycontacts",null);
if (cursor.moveToFirst()) {
do {
Person person = new Person();
person.name = cursor.getString(cursor.getColumnIndex(CONTACTS_COLUMN_STUNAME));
person.id = cursor.getInt(cursor.getColumIndex(CONTACTS_COLUMN_ID));
arraylist.add(prson);
} while (cursor.moveToNext());
}
return arraylist;
}
Then in your adapter you use the ID in the Person object to reference it, instead of the position.

Are you refreshing your "List of Names" from your android App afer every insert/delete?
Maybe by calling getAllStudentContacts() from your code after every insert/delete to refill your List of names of your android app?
Good Luck

How to inflate views programmatically in vertical order

I just picked up Android developing. I decided to make a ToDo-list(simple and has a somewhat visual body) but I'm facing problems with inflating Layout in order.
Basically I have an Activity that collects information that is supposed to be shown in Main Activity. I get one of them showing up, but can't figure out how to add more than one of them. They'd be showing up in vertical order as the title says.
Main:
package com.example.victor.todo;
import android.content.Context;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewManager;
import android.widget.CheckBox;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
import android.widget.TextView;
public class MainActivity extends ActionBarActivity {
String NEW_TASK, NEW_TASK_DETAILS;
int pos = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
if (id == R.id.action_add_task){
Intent i = new Intent(this,AddTaskActivity.class);
startActivityForResult(i, 1);
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == 1){
if(resultCode == RESULT_OK){
String task = data.getStringExtra("task");
String taskDetails = data.getStringExtra("details");
String taskInfo = data.getStringExtra(AddTaskActivity.EXTRA_NAME);
Log.i("TAG", "task: " + task);
Log.i("TAG", "task info: " + taskDetails);
AddTask(task, taskDetails);
} else {
//DO SOMETHING IF NO INFO IS RETURNED
}
}
}
public void AddTask(String task, String details){
TextView tw = (TextView)findViewById(R.id.addMainHint);
((ViewManager) tw.getParent()).removeView(tw);
LinearLayout linearLayoutMain = (LinearLayout) findViewById(R.id.mainLinearLayout);
View v = getLayoutInflater().inflate(R.layout.task_listing, null);
linearLayoutMain.addView(v);
TextView taskName = (TextView) v.findViewById(R.id.single_task_info);
taskName.setText(task);
CheckBox taskCheckBox = (CheckBox) v.findViewById(R.id.single_task_checkbox);
taskCheckBox.setChecked(false);
/*

*/
/*
RelativeLayout layout = (RelativeLayout) findViewById(R.id.single_task_layout);
TextView ll = new TextView();
*/
}
public void TaskClicked(){
}
}
task_listing.xml(a relative layout that acts as the container of the info):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="70dp"
android:id="#+id/single_task_layout"
>
<TextView
android:layout_width="300dp"
android:layout_height="30dp"
android:id="#+id/single_task_info"
android:layout_marginTop="20dp"
android:textColor="#color/primary_material_dark"
android:textSize="20sp"
android:layout_alignParentRight="true"
android:layout_marginLeft="40dp"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:clickable="true" />
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/single_task_checkbox"
android:layout_gravity="left"
android:layout_toLeftOf="#id/single_task_info"
android:layout_marginTop="15dp"
android:layout_marginLeft="15dp"
android:enabled="true"
android:clickable="true"
android:onClick="TaskClicked"
android:visibility="visible" />
</RelativeLayout>
I guess I'm using the wrong tools but I don't even know what to search for! I don't have problems with Java itself but the design is giving me serious headache. I've been trying to figure this out for hours(it's 7.48 in the morning)!
Again, it works if I add just one of the layouts so the other javas and xmls aren't probably that important.
Thanks!

Use a listview is correct. Try doing this (A little bit more elaborate than what you have but worth it.
Create a Task object that implements Pacelable. This object can be sent back in the result of AddTaskActivity
public class Task implements Parcelable {
private String myTask;
private String myDetails;
public static final Parcelable.Creator<Task> CREATOR
= new Parcelable.Creator<Task>() {
public Task createFromParcel(Parcel in) {
return new Task(in);
}
public Task[] newArray(int size) {
return new Task[size];
}
};
public Task() {}
public Task(Parcel in){
myTask = in.readString();
myDetails = in.readString();
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(myTask);
dest.writeString(myDetails);
}
}
And this is your class slightly modified
public class MainActivity extends ActionBarActivity {
private Adapter myAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myAdapter = new Adapter();
ListView listView = (ListView)findViewById(android.R.id.list);
listView.setAdapter(myAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
if (id == R.id.action_add_task){
Intent i = new Intent(this,AddTaskActivity.class);
startActivityForResult(i, 1);
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == 1){
if(resultCode == RESULT_OK){
myAdapter.addTask(data.getParcelableExtra(AddTaskActivity.[key constant]));
} else {
//DO SOMETHING IF NO INFO IS RETURNED
}
}
}
public void TaskClicked(){
}
private class Adapter extends BaseAdapter {
private List<Task> myTasks;
public Adapter() {
myTasks = new ArrayList<Task>();
}
public void addTask(Task task) {
myTasks.add(task);
notifyDataSetChanged();
}
#Override
public int getCount() {
return myTasks.size();
}
#Override
public Object getItem(int position) {
return myTasks.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView tw = (TextView)findViewById(R.id.addMainHint);
((ViewManager) tw.getParent()).removeView(tw);
convertView = getViewNotNull(convertView, parent);
Task task = (Task)getItem(position);
TextView taskName = (TextView) convertView.findViewById(R.id.single_task_info);
taskName.setText(task.getTask());
}
private View getViewNotNull(View convertView, ViewGroup parent) {
if(convertView == null) {
convertView = View.inflate(parent.getContext(), R.layout.task_listing)
//here you should create a viewholder and set it on the view using setTag()
}
return convertView;
}
}
}
I quickly threw this together so hopefully it has what you need to get started
you'll still need to implement the item click listener on the listview as well as the check status for the checkboxes

Use ListView to get it done easily.

If I am reading it correctly and your BasicDialogFragment code is like this
then all you need to do is add
public void OnNameEntered(String nameEntered){
//Do Something Here
}
to your ActivityA.java
EDIT
modify the following functions as follows:
private void visTekst(String nameEntered) {
if(buttonOK.isPressed()){
textA2.setText(nameEntered);
Toast melding = Toast.makeText(getApplicationContext(),
dialog_fornavn.getText(), Toast.LENGTH_SHORT);
melding.show();
} else if(buttonCancel.isPressed()){
startAB();
}
}
and call it as
public void OnFragmentInteractionListener(String nameEntered){
visTekst(nameEntered);
}
You need to setup your listeners as it is mentioned in the code that you have used
in your BasicDialogFragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_basic_dialog, container, false);
this.getDialog().setTitle("First Name");
buttonCancel = (Button) findViewById(R.id.buttonCancel);
buttonOK = (Button) findViewById(R.id.buttonOK);
buttonCancel.setOnClickListner(new View.OnClickListener(View v){
onButtonPressed(/*Your custom URI*/Uri uri);
});
buttonOK .setOnClickListner(new View.OnClickListener(View v){
onButtonPressed(/*Your custom URI*/Uri uri);
});
return v;
}

For this issue, there are two ways, one is direct cast to hosted Activity to get activity instance. Another is using one interface that defined in DialogFragment but implemented by hosted Activity.
For detail please follow my previous post Call activity from DialogFragment.

} catch (Exception e) {
e.printStackTrace();
}
}
private OnClickListener cancel_button_click_listener = new OnClickListener() {
public void onClick(View v) {

In place of layout pass spinner object of your view:
replace
pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);
with
pwindo.showAtLocation(spinner, Gravity.CENTER, 0, 0);
And to open popup window just below your spinner use below code
pwindo.showAsDropDown(spinner, 0, 0);
Update your CustomOnItemSelectedListener class as:
public class CustomOnItemSelectedListener implements OnItemSelectedListener {
Context mCtx;
public CustomOnItemSelectedListener(Context ctx) {
this.mCtx = ctx;
}
#Override
public void onItemSelected(AdapterView<?> parent, View view, int pos,
long id) {
// TODO Auto-generated method stub
((MainActivity) mCtx).initiatepopupwindow();
Toast.makeText(parent.getContext(),
parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG)
.show();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}

May I suggest an easy way to do that? Suppose I have a global variable for class AddFromContacts as,
public static boolean checked=false;
now, inside the button click (Button to select/deselect all), leave the loop you wrote as it is. Include the following.
if(checked)
checked=false;
else
checked=true;
Then inside Adapter getView(),
cb.setChecked(AddFromContacts.checked);
Eg: worked for me
public class MainActivity extends Activity {
ListView lv;
Button b1;
boolean checked=false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv=(ListView) findViewById(R.id.listView1);
b1=(Button) findViewById(R.id.button1);
Myadapter adapter=new Myadapter();
lv.setAdapter(adapter);
b1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(checked)
checked=false;
else
checked=true;
for (int i = 0; i < lv.getChildCount(); i++) {
ViewGroup item = (ViewGroup) lv.getChildAt(i);
CheckBox checkbox = (CheckBox) item
.findViewById(R.id.checkBox1);
checkbox.setChecked(checked);
}
}
});
}
class Myadapter extends BaseAdapter{
CheckBox cb;
LayoutInflater mInflater;
public Myadapter() {
mInflater = (LayoutInflater) MainActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return 15;
}
#Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = mInflater.inflate(R.layout.item, null);
cb = (CheckBox) vi.findViewById(R.id.checkBox1);
cb.setTag(position);
cb.setChecked(checked);
return vi;
}
}
}
Also, I can see a method public void setChecked(int position, boolean isChecked). If you meant to call this, change the code to setChecked(position,mCheckStates.get(position, false));
