Android: implementing Checkbox List with ListFragment and ArrayAdapter - android-arrayadapter

Question

I am converting a working application to Fragments. My checkbox list is not displaying the labels, and I am guessing, the id's. I am new to Android/Java and this is my first post to Stackoverflow, so apologies if the question is simple or not following correct protocol.
My ListFragment is as follows:
import java.util.ArrayList;
import java.util.List;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.TextView;
public class DistributionTransFragment extends ListFragment {
protected TextView subheader;
protected Context mContext;
protected DatabaseHandler db;
protected String user_id;
protected String user;
protected String recipients;
protected int number;
protected LayoutInflater inflater;
protected View v;
DistributionArrayAdapter dataAdapter = null;
public DistributionTransFragment(){
super();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
v = inflater.inflate(R.layout.distribution_fragment, container, false);
mContext = getActivity().getApplicationContext();
db = new DatabaseHandler(mContext);
subheader = (TextView)v.findViewById(R.id.textView2);
subheader.setText("Spent On?");
displayListView();
checkButtonClick();
return v;
}
private void displayListView() {
ArrayList<Participant> distributionList = new ArrayList<Participant>();
Participant participant;
List<User> users = db.getAllUsers();
for (User u : users) {
user_id = String.valueOf(u.getID());
user = u.getUser();
participant = new Participant(user_id, user, false);
distributionList.add(participant);
}
//create an ArrayAdaptar from the String Array
dataAdapter = new DistributionArrayAdapter(mContext, R.layout.distributionlist, distributionList);
setListAdapter(dataAdapter);
}
private class DistributionArrayAdapter extends ArrayAdapter<Participant> {
private ArrayList<Participant> distributionList;
public DistributionArrayAdapter(Context context, int textViewResourceId, ArrayList<Participant> distributionList) {
super(context, textViewResourceId, distributionList);
this.distributionList = new ArrayList<Participant>();
this.distributionList.addAll(distributionList);
}
private class ViewHolder {
TextView code;
CheckBox name;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
Log.v("ConvertView", String.valueOf(position));
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.distributionlist, null);
holder = new ViewHolder();
holder.code = (TextView) convertView.findViewById(R.id.code);
holder.name = (CheckBox) convertView.findViewById(R.id.checkBox1);
convertView.setTag(holder);
Log.d("HOLDER CODE", (holder.code).toString());
holder.name.setOnClickListener( new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v ;
Participant participant = (Participant) cb.getTag();
participant.setSelected(cb.isChecked());
}
});
} else {
holder = (ViewHolder) convertView.getTag();
}
Participant participant = distributionList.get(position);
holder.name.setText(participant.getName());
holder.name.setChecked(participant.isSelected());
holder.name.setTag(participant);
return convertView;
}
}
private void checkButtonClick() {
Button myButton = (Button) v.findViewById(R.id.button1);
myButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
final ArrayList<Participant> distributionList = dataAdapter.distributionList;
// Do Stuff
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setMessage(tempTransaction);
builder.setCancelable(false);
builder.setPositiveButton("Commit", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Do More Stuff
Intent intent = new Intent(mContext, Home.class);
startActivity(intent);
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Do Other Stuff
Intent intent = new Intent(mContext, Home.class);
startActivity(intent);
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
}
}
My XML for the list is as follows:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#color/white"
android:padding="15dip" >
<CheckBox
android:id="#+id/checkBox1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:focusable="false"
android:focusableInTouchMode="false" />
<TextView
android:id="#+id/code"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/checkBox1"
android:layout_alignBottom="#+id/checkBox1"
android:layout_toRightOf="#+id/checkBox1"
android:textSize="15sp" />
</RelativeLayout>
My XML for the fragment is as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/grey">
<RelativeLayout
android:id="#+id/subheader"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/secondheader"
android:orientation="vertical" >
<TextView
android:id="#+id/textView2"
style="#style/subheader" />
<TextView
android:id="#+id/textView3"
style="#style/info" />
</RelativeLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/subheader"
android:layout_above="#+id/footer"
android:orientation="vertical" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:id="#id/footer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#color/grey"
android:layout_alignParentBottom="true" >
<Button
android:id="#+id/button1"
style="#style/button.form"
android:text="#string/moneyspent" />
</LinearLayout>
</RelativeLayout>
Any help would be greatly appreciated.

I nutted it out, so thought I would post my answer in case others have the same problem. It was my context. It should have been:
mContext = getActivity();
