Fetching values from Cursor but Application Crashes

I am trying to fetch values from the database when I click on the view button which is another activity for navigation when I click on the view all button the CustodianViewActivity is triggered to display all the values from the database on a list view but in my case the application crashes every time I try to view the data from the database. Am not sure where I am going wrong.

Can't populate textview from database

I can't understand why I doesen't get any data out of the database. I have to admit that I am confues about listviews, textviews and adapters.
The database contains a person and a gift. That should be poured into a textview. Somehow it seems that I have to make a listview, but.... I am confused.
I have read a lot, and worked hard, but I have no idea. I would appreciate it if anyone could help me :-)
The only thing that happens is that na empty list is appearing.
Here is the code:
Main Activity.java:
package com.example.julegaveliste2;
import android.app.ListActivity;
import android.content.ContentValues;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;

You should try to replace your SimpleCursorAdapter with an ArrayAdapter. To do this we would need a few modifications to your code. We need a new class in your application, which I will call PresentItem, an ArrayAdapter for your list, an XML layout for each row in the list, and a method for converting SQLite rows to PresentItems. First out is the new model, PresentItem:
public class PresentItem {
private String name, present;
private int id;
public PresentItem(int id, String name, String present) {
// Init
}
// Getters, setters, etc.
}
So, when we now read from your database, we can convert each rows we get from our query to new PresentItems:
public List<PresentItem> getPresentItems(SQLiteDatabase db) {
Cursor cursor = db.query("julegaveliste2",
new String[] {"_id", "person", "gave"}, null, null, null, null, null);
List<PresentItem> result = new ArrayList<PresentItem>();
PresentItem item;
if (cursor != null && cursor.moveToFirst()) {
int index = cursor.getColumnIndex("_id");
int id = cursor.getInt(index));
index = cursor.getColumnIndex("name");
String name = cursor.getString(index));
index = cursor.getColumnIndex("present");
String present = cursor.getString(index);
item = new PresentItem(id, name, present);
result.add(item);
}
return result;
}
Once we have the PresentItems parsed from the database, we need a way to display them. To display the PresentItems in your app, we need our own ArrayAdapter, which would look something like this:
public class PresentListAdapter extends ArrayAdapter<PresentItem> {
private Context ctx;
private List<PresentItem> presentItems;
public PresentListAdapter(Context ctx, int layoutResourceId, List<PresentItem> presentItems) {
super(context, layoutResourceId, presentItems);
this.ctx = ctx;
this.presentItems = presentItems;
}
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = ((Activity) ctx).getLayoutInflater();
convertView = inflater.inflate(mLayoutResourceId, parent, false);
}
PresentItem item = presentItems.get(position);
((TextView) convertView.findViewById(R.id.row_id)).setText("" + item.getId());
((TextView) convertView.findViewById(R.id.name)).setText(item.getName());
((TextView) convertView.findViewById(R.id.present)).setText(item.getPresent());
return convertView;
}
To use the adapter in your app, do something like this:
public void visListe(SQLiteDatabase db){
List<PresentItem> items = getPresentItems(db);
PresentItemAdapter adapter = new PresentItemAdapter(this, R.layout.presentListItem, items);
ListView listView = (ListView) findViewById(R.id.listView1);
listView.setAdapter(adapter);
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}
And, as you might notice, our adapter uses presentListItem as its layout, which we define in res/layout/presentListItem.xml as:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/row_id"
/>
<TextView android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/name"
/>
<TextView android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/present"
/>
</LinearLayout>
I hope I made it clear and beware bugs in the code - I wrote most of it from memory with a few quick Google searches to help me :) Ask if you need anymore help ^^

ListFragment and Custom Adapter Issue

Two issue with List Fragment: 1. I have a class that extends ListFragments.In the onCreated, I am setting my custom Adapter. The issue is that when the user logs in, the adadpter is null and would not have a value until the user searches for an owner. As a result, it throws an exception when it tries to set up the listadapter and it finds the ArrayAdapter object to be null. I have a custome layout that has a listview and a textview, but I still gets the error. See sample code below. I bold the line of code where the issue happens. Also, I bold few other section where I think it may be important to notice.
I implemented Parcelable in the class "Owner" so that I can pass the object as a ParcelableArray. Even though the object is not null, retrieving it in the OwnerDetail class shows null as if I did not pass it it. I've seen several example, but I am not able to get it right. What am I doing wrong here?
Note: If I were to call the AsyncTask in the OwnerDetail class and set the ListAdapter, it will work fine. The issue with that is that it will display a list of owners as soon as the user is logged in which is not the expected behavior. The behavior that I want is to login first, search for an owner, display the owner, double click on an owner, and finally display a list of cars that the owner owns. I am doing this project, so I can learn how to use ListFraments.

Your code has a lot of problems:
1 Never call lifecycle methods on your own like you do in the OwnerDetail class with super.onActivityCreated(savedInstanceState);
2 Bundle values = getActivity().getIntent().getExtras(); ... values.getParcelableArray("test"); will normally fail because this piece of code will get the activity reference, get the Intent that started the activity and then try to find data passed in under the test key in that Intent. You don't pass such data to the People activity so there will be nothing to be found. You'd normally want to pass a Bundle containing the data at the moment of the creation of the fragment.
3 If you use the fragment in the xml layout you'll not be able to use a Bundle to pass data, instead you either add the fragment manually with transactions and then use a Bundle or you create a setter method in the fragment class and use that. So instead of Bundle data = new Bundle(); data.putParcelableArray("test", myOwners);, which does nothing, get a reference to your fragment and pass the myOwners array through a method.
4 Your AsyncTask will be pretty useless if you use them with .get() because the get() method will wait the AsyncTask to finish, blocking the UI tread as well. Instead you should just start the AsyncTask and then in the onPostExecute() pass the data around.
Here is an example with a simple method which will not change most of your code(which will happen if you manually add the fragments):
// where you start the owner asynctask
if(!searchByName.matches("")) {
OnwerAsyncTask asynTask = new OnwerAsyncTask(People.this);
asynTask.execute("");
}
//...
Then change the OnwerAsyncTask like this:
public class OnwerAsyncTask extends AsyncTask<String, Void, List<Owner>> {
private List<Owner> items = null;
private FragmentActivity mActivity;
public OnwerAsyncTask(FragmentActivity activity) {
mActivity = activity;
}
// doInBackground()...
#Override
protected void onPostExecute(List<Owner> result) {
//I'm assuming that items is the data you want to return, so
// find the OwnerDetail fragment and directly assign the data
OwnerDetail fragment = (OwnerDetail)mActivity.getSupportFragmentManager().findFragmentById(R.id.fOwnerDetail);
fragment.setData(); // to setData you'll pass the data you have in the AsyncTask
// the items list? or you transform that into an array?
}
and in the OwnerDetail fragment:
public class OwnerDetail extends ListFragment {
OwnerAdapter ownerAdapter = null;
public void setData() {
// update the adapter, create a new one etc.
}

insert code causing app to stop

i have this set of codes used for inserting data into my sqlite database. but why does my app stop when i try to insert?
package edu.nyp.project;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.view.View.OnClickListener;
public class AddData extends Activity {
Button insertButton = null;
EditText shopText= null;
EditText dealText= null;
EditText locationText= null;
EditText websiteText= null;
EditText categoryText= null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.adddata);
insertButton = (Button) findViewById(R.id.button1);
insertButton.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
DBAdapter dbAdapter = new
DBAdapter(getApplicationContext());
try{
dbAdapter.open();
String shop = shopText.getText().toString();
String deal = dealText.getText().toString();
String location = locationText.getText().toString();
String website = websiteText.getText().toString();
String category = categoryText.getText().toString();
}
catch(Exception e){
Log.d("Add Data ", e.getMessage());
}
finally{
if (dbAdapter != null)
dbAdapter.close();
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.adddata, menu);
return true;
}
}
here is the code for the DBAdapter file for reference.

becouse I think you dont bind that components with findViewById:
shopText.getText().toString();
String deal = dealText.getText().toString();
String location = locationText.getText().toString();
String website = websiteText.getText().toString();
String category = categoryText.getText().toString();
result should be a NullPointerException.
Show us youre LogCat...
Otherwise add this to youre on create and try it again:
shopText= (EditText)findViewById(R.id.THE_ID);
dealText= (EditText)findViewById(R.id.THE_ID);;
locationText= (EditText)findViewById(R.id.THE_ID);;
websiteText= (EditText)findViewById(R.id.THE_ID);;
categoryText= (EditText)findViewById(R.id.THE_ID);;

First of all get all EditText By id.
try{
shopText=(EditText)findViewById(R.id.shopText)
//get All EditText by id like above
dbAdapter.open();
String shop = shopText.getText().toString();
String deal = dealText.getText().toString();
String location = locationText.getText().toString();
String website = websiteText.getText().toString();
String category = categoryText.getText().toString();
//secondly
dbAdapter.insertDeal(shop,deal,location,website,category);
}
