I have an activity that is works fine and displays data obtained from a table query. With an OnItemClick method, I have it set up so that if a row is selected, a new activity starts with a new ListView, but a lot of the elements from the original ListView are in the new listview, including a toggle button on each row, and a text view. Any idea what could be causing this?
This is the initial ListView. The buttons don’t show up, just everything in the ListView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#81BEF7"
android:orientation="vertical" >
<Button
android:id="@+id/btnAddNurseToRoster"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/add"
android:focusable="true"/>
<Button
android:id="@+id/btnRemoveNurseFromRoster"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@+id/btnAddNurseToRoster"
android:layout_toRightOf="@+id/btnAddNurseToRoster"
android:text="@string/delete"
android:focusable="true"/>
<ListView
android:id="@+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="@+id/btnAddNurseToRoster"
android:textColor="#FFFFFF"
android:textStyle="bold"/>
</RelativeLayout>
New ListView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#81BEF7"
android:orientation="vertical" >
<TextView
android:id="@+id/tvAssignmentsText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="25dp"
android:textColor="#FFFFFF"
android:text="Assignments"
android:gravity="center_horizontal"
android:background="#663399"
/>
<ListView
android:id="@+id/lvAssignmentsList"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="@+id/tvAssignmentsText"
android:paddingTop="20dp"
android:textColor="#FFFFFF"
android:textStyle="bold"/>
</
And here’s the code that calls the new ListView:
package com.deadEddie.staffingmanagement;
import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.support.v4.widget.SimpleCursorAdapter;
import android.util.Log;
import android.widget.ListAdapter;
import android.widget.ListView;
public class ShowAssignments extends Activity {
DbCommunicator getAssignmentsList;
ListView assignmentsList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.assignments);
displayList();
}
private void displayList() {
// instantiate ListView object
assignmentsList = (ListView) findViewById(R.id.lvAssignmentsList);
// instantiate variables for CursorAdapter
int [] to = new int [] {R.id.rbAssignmentsList };
String [] from = new String [] {DbCommunicator.KEY_ROOM_NUMBER};
// instantiate getAssignmentsList with new DbCommunicator object and open
getAssignmentsList = new DbCommunicator(this);
getAssignmentsList.open();
// get and manage cursor
Cursor assignmentsCursor = getAssignmentsList.getAssignments(this);
startManagingCursor(assignmentsCursor);
// list adapter
ListAdapter assignmentsListAdapter = new SimpleCursorAdapter(this, R.layout.nurse_list, assignmentsCursor, from, to, 0);
assignmentsCursor.moveToNext();
// set ListView
assignmentsList.setAdapter(assignmentsListAdapter);
assignmentsList.setItemsCanFocus(true);
}
}
Adding the code used to populate the original ListView:

Code that calls original layout I’m trying to change:
package com.deadEddie.staffingmanagement;
import android.app.Dialog;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.os.Handler;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.Button;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.AdapterView.OnItemClickListener;
public class EditRoster extends ListActivity implements OnClickListener {
String TAG = "EditRoster";
Button addNurse;
Button deleteNurse;
DbCommunicator rosterView;
ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_roster);
addNurse = (Button) findViewById(R.id.btnAddNurseToRoster);
deleteNurse = (Button) findViewById(R.id.btnRemoveNurseFromRoster);
displayNurseRoster();
displayDialog();
addNurse.setOnClickListener(this);
deleteNurse.setOnClickListener(this);
}
// method to put timer on dialog
public void timerDelayRemoveDialog(long time, final Dialog dialogView){
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
dialogView.dismiss();
}
}, time);
}
private void displayDialog() {
Dialog d = new Dialog(this);
d.setTitle("Select Nurse to Adjust Assignments");
d.show();
timerDelayRemoveDialog(2000, d);
}
public void displayNurseRoster(){
listView = (ListView) findViewById(android.R.id.list);
// int variables filled with NURSE_TABLE data
int[] to_nurseTable = new int[] {
// int list for data from NURSE_TABLE fields
R.id.rosterDutyStatus,
R.id.rosterListLname,
R.id.rosterListFname,
R.id.rosterListMI,
R.id.rosterListID,
// int list for data from ASSIGNMENTS_TABLE fields
R.id.firstAssignment};
// String array holding data fields from NURSE_TABLE
String[] from_nurseTable = new String [] {
// fields from NURSE_TABLE
DbCommunicator.KEY_DUTY_STATUS,
DbCommunicator.KEY_LNAME,
DbCommunicator.KEY_FNAME,
DbCommunicator.KEY_MI,
DbCommunicator.KEY_NURSE_ROWID,
DbCommunicator.KEY_ROOM_NUMBER};
// instantiate instance of DbCommunicator object
rosterView = new DbCommunicator(this);
// open instance
rosterView.open();
// get & manage cursor for NURSE_TABLE data
Cursor nurseTableCursor = rosterView.getNurseRosterCursor(this);
startManagingCursor(nurseTableCursor);
// instantiate cursor adaptor
ListAdapter nurseTableAdapter = new SimpleCursorAdapter(this,
R.layout.nurse_list, nurseTableCursor, from_nurseTable, to_nurseTable);
nurseTableCursor.moveToNext();
// set listView
listView.setAdapter(nurseTableAdapter);
rosterView.close();
listView.setItemsCanFocus(true);
listView.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Log.i(TAG, "onItemClickListener set");
Intent showAssignments = new Intent("com.deadEddie.staffingmanagement.SHOWASSIGNMENTS");
startActivity(showAssignments);
}
});
}// displayNurseRoster()
@Override
public void onClick(View v)
{
switch (v.getId())
{
case R.id.btnAddNurseToRoster:
Intent add = new Intent("com.deadEddie.staffingmanagement.ADDNURSETOROSTER");
startActivity(add);
break;
case R.id.btnRemoveNurseFromRoster:
break;
} // switch
}
}
Okay. Got it. Just realized that I mistakenly used the same layout (nurse_list) when I instantiate the ListAdapter in each method so it tried to apply my new data query to the original layout (which was screwed up of course). Thanks for taking a look though, really appreciate it.
Sorry if this wastes anyone’s time. Maybe a lesson for other newbies out there.
