I have a custom baseadapter that creates comment boxes. Everything works great on it until I want to add data. When I try to add the data it deletes the previous data and adds the new data. How do I make it so it keeps all the data? Is my Add method incorrect? Here is my baseadapter,
class CreateCommentLists extends BaseAdapter{
Context ctx_invitation;
String[] listComments;
String[] listNumbers;
String[] listUsernames;
public CreateCommentLists(String[] comments, String[] usernames, String[] numbers, DashboardActivity context)
{
super();
ctx_invitation = context;
listComments = comments;
listNumbers = usernames;
listUsernames = numbers;
}
#Override
public int getCount() {
if(null == listComments)

return 0;
}
// TODO Auto-generated method stub

#Override

// TODO Auto-generated method stub
return listComments[position];
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = null;
try
{
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater li = (LayoutInflater)ctx_invitation.getSystemService(inflater);
v = li.inflate(R.layout.list_item, null);
TextView commentView = (TextView)v.findViewById(R.id.listComment);
TextView NumbersView = (TextView)v.findViewById(R.id.listNumber);
TextView usernamesView = (TextView)v.findViewById(R.id.listPostedBy);
Button usernameButton = (Button)v.findViewById(R.id.listUsernameButton);
Button numberButton = (Button)v.findViewById(R.id.listNumberButton);
commentView.setText(listComments[position]);
NumbersView.setText(listNumbers[position]);
usernamesView.setText(listUsernames[position]);
usernameButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent i = new Intent(getApplicationContext(), ProfileActivity.class);
i.putExtra("usernameOfProfile",listUsernames[position]);
startActivity(i);
finish();
}
});
numberButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Intent i = new Intent(getApplicationContext(), ProfileActivity.class);
i.putExtra("NumberProfile",listNumbers[position]);
startActivity(i);
finish();
}
});
}
catch(Exception e)
{
e.printStackTrace();
}
return v;
}
public void add(String[] comments, String[] usernames,
String[] numbers) {
listComments = comments;
listNumbers = usernames;
listUsernames = numbers;
}

{

public View getView1(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = null;
try
{
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater li = (LayoutInflater)ctx_invitation.getSystemService(inflater);
v = li.inflate(R.layout.list_item, null);
TextView commentView = (TextView)v.findViewById(R.id.listComment);
TextView NumbersView = (TextView)v.findViewById(R.id.listNumber);
TextView usernamesView = (TextView)v.findViewById(R.id.listPostedBy);
Button usernameButton = (Button)v.findViewById(R.id.listUsernameButton);
Button numberButton = (Button)v.findViewById(R.id.listNumberButton);
commentView.setText(listComments[position]);
NumbersView.setText(listNumbers[position]);
usernamesView.setText(listUsernames[position]);
usernameButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {

Setting the adapter:
final CreateCommentLists mycmlist = new CreateCommentLists(comments, usernames, numbers, DashboardActivity.this);
lstComments = (ListView)findViewById(android.R.id.list);
lstComments.setAdapter(mycmlist);
This is what how I call the add method,
mycmlist.add(comments,usernames,numbers);
mycmlist.notifyDataSetChanged();
In your add method you're setting the arrays to new values listComments = comments; That's replacing your old data with the new data.
You could use System.arrayCopy() to resize your listArrays to the new size and append the new items. A much less tedious approach, however, would be to store your arrays as List<String>, allowing you to add more items without worrying about resizing lists.
The result would look something like this...
public class CommentsAdapter extends BaseAdapter
{
private LayoutInflater inflater;
private List<String> comments;
private List<String> numbers;
private List<String> usernames;
public CommentsAdapter(Context context)
{
inflater = LayoutInflater.from(context);
comments = new ArrayList<String>();
numbers = new ArrayList<String>();
usernames = new ArrayList<String>();
}
public void add(String[] comments, String[] numbers, String[] usernames)
{
this.comments.addAll(Arrays.asList(comments));
this.numbers.addAll(Arrays.asList(numbers));
this.usernames.addAll(Arrays.asList(usernames));
notifyDataSetChanged();
}
#Override
public int getCount()
{
if (comments == null)
return 0;
return comments.size();
}
#Override
public String getItem(int position)
{
return comments.get(position);
}
#Override
public long getItemId(int position)
{
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
if (convertView == null)
{
convertView = inflater.inflate(R.layout.list_item, parent, false);
convertView.setTag(new ViewHolder(convertView));
}
ViewHolder holder = (ViewHolder) convertView.getTag();
holder.commentView.setText(comments.get(position));
//Other view bind logic here...
return convertView;
}
private static class ViewHolder
{
public TextView commentView;
public TextView numbersView;
public TextView usernamesView;
public Button usernameButton;
public Button numberButton;
public ViewHolder(View v)
{
commentView = (TextView) v.findViewById(R.id.listComment);
numbersView = (TextView) v.findViewById(R.id.listNumber);
usernamesView = (TextView) v.findViewById(R.id.listPostedBy);
usernameButton = (Button) v.findViewById(R.id.listUsernameButton);
numberButton = (Button) v.findViewById(R.id.listNumberButton);
}
}
}
I also highly recommend reading this page on the Android Developer's site: http://developer.android.com/training/improving-layouts/smooth-scrolling.html
Your current adapter implementation is very inefficient, and that page should help you iron out some kinks.
You probably need to add the String[] array to the existing one, instead of replacing it.
Add this function which joins two arrays (Sadly there is no already-implemented method for Java):
String[] concat(String[] A, String[] B) {
String[] C= new String[A.length + B.length];
System.arraycopy(A, 0, C, 0, A.length);
System.arraycopy(B, 0, C, A.length, B.length);
return C;
}

And then change the add method to this:
public void add(String[] comments, String[] usernames,
String[] numbers) {
listComments = concat(listComments, comments);
listUsernames = concat(listUsernames, usernames);
listNumbers = concat(listNumbers, numbers);
}
And you had a typo in your code. In the add method, the listUsernames and listNumbers should be swapped I think.. I fixed it for you.

I have a ListView Item that has 2 buttons in it. There are multiple ListView items so there are many buttons. How can I assign a different value to each button? What I want to happen is every button leads to the same activity, but when it goes to the new activity it sends a value that the button was assigned. Then the activity can handled the value. I want the values assigned to the buttons to be the same as what the text is set to, here is my baseAdapter
class CreateCommentLists extends BaseAdapter{
Context ctx_invitation;
String[] listComments;
String[] listNumbers;
String[] listUsernames;
public CreateCommentLists(String[] comments, String[] usernames, String[] numbers, DashboardActivity context)

listComments = comments;
listNumbers = usernames;
listUsernames = numbers;

NumbersView.setText(listNumbers[position]);
usernamesView.setText(listUsernames[position]);
usernameButton.setText("Go to " + listUsernames[position]);
numberButton.setText("Go to " + listNumbers[position]);
}
catch(Exception e)

does anyone know how to color the background of each row in a listview as they are created?
I have an arraylist which is pulled from my database and populates a layout with a listview in it.
I suspect there might be a way to do it with a simpleadaptor but cant figure it out.
Any help would be much appreciated :)

Create an Adapter Class, and control each Row's color in it, then set it as adapter of ListView
Here is a sample code from one of my projects, check getView function:
public class ListAdapter extends BaseAdapter {
private LayoutInflater myInflater;
private List<Poet> list;
public ListAdapter(Context context) {
super();
myInflater = LayoutInflater.from(context);
Log.d("Ganjoor", "Data passed to the adapter.");
}
static class ViewHolder {
TextView tvName;
}
public void setData(List<Poet> list) {
this.list = list;
}
#Override
public int getCount() {
return list.size();
}
#Override
public Poet getItem(int position) {
return (null == list) ? null : list.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = myInflater.inflate(R.layout.list_adapter, parent,
false);
holder = new ViewHolder();
holder.tvName = (TextView) convertView.findViewById(R.id.tvName);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.tvName.setTag(list.get(position).getId());
holder.tvName.setText(list.get(position).getName());
// Log.d("Ganjoor", "Adapter: " + list.get(position).getName());
if (position % 2 == 0) {
convertView.setBackgroundResource(R.drawable.grad_blue);
} else {
convertView.setBackgroundResource(R.drawable.row_style);
}
return convertView;
}
}
As #Nikita Beloglazov states, you can do this by implementing a custom ArrayAdapter, putting your coloring scheme in the getView Override method. See ArrayAdapter doc.
I have an application it have two activities. When press a button in the main activity, it shows customized listview, then I press hard back button and go to the main page of my application.
Then I again press the same button and go to the listview it shows the repeated values in the listview.
Any one have any sloution please???

I Have 2D Array and this 2D Array has Strings. I would like to know How to Display the Strings in ListView?how to scroll both vertically and horizontally?
String[][] board = new String[][] {{"1","10","100"},{"hi0","1hello","test"},{"test31","test32","test43"}};
It seem to be you are asking basic things, How to use ListView. please check it you will get all about ListView.
Android ListView and ListActivity
It is to display two-d array in list view.Here's my source code in which i have implemented 2-d array in list view
My Adapter class:-
public class MyArrayAdapter extends ArrayAdapter<List>{
QuickActionDemo quickActionDemo;
public Activity context;
public List<List> list;
int CAMERA_PIC_REQUEST=10;
private int selectedPos = -1;
int clickPosition,rowPosition;
Camera camera;
private static final String TAG = "CameraDemo";
public MyArrayAdapter(Activity context,List<List> list) {
super(context,R.layout.attach_pic,list);
this.context = context;
this.list = list;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position+1;
}
static class ViewHolder {
public TextView tv1,tv2,tv3;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View rowView = null;
final ViewHolder holder = new ViewHolder();
if (convertView == null) {
LayoutInflater inflator = context.getLayoutInflater();
rowView = inflator.inflate(R.layout.attach_pic, null);
holder.tv1 = (TextView) rowView.findViewById(R.id.defectpic);
holder.tv2 = (TextView) rowView.findViewById(R.id.no_of_uploded_pics);
holder.tv3 = (TextView) rowView.findViewById(R.id.camera);
holder.tv3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// Intent in = new Intent(getContext(),QuickActionDemo.class);
// context.startActivityForResult(in,0);
}
});
rowView.setTag(holder);
List itemVal1 = (List)getItem(position);
String st1 = (String)itemVal1.get(0);
holder.tv1.setText(st1);
List itemVal2 = (List)getItem(position);
String st2 = (String)itemVal2.get(1);
holder.tv2.setText(st2);
} else {
rowView = convertView;
((ViewHolder) rowView.getTag()).tv1.setTag(list.get(position));
((ViewHolder) rowView.getTag()).tv2.setTag(list.get(position));
((ViewHolder) rowView.getTag()).tv3.setTag(list.get(position));
}
return rowView;
}
#Override
public int getItemViewType(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public int getViewTypeCount() {
// TODO Auto-generated method stub
return list.size();
}
}
Here's my activity class:-
public class MyActivity extends ListActivity {
Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
// requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); // to hide the virtual keyboard
setContentView(R.layout.defect_pic_listview);
try{
ArrayAdapter<List> adapter = new MyArrayAdapter(this,makeList());
setListAdapter(adapter);
}
}
private List<List> makeList(){
List<List> all = new ArrayList();
String[] newArray1 = {"Defect Picture1", "2"};
List<String> newListObject1 = Arrays.asList(newArray1);
String[] newArray2 = {"Defect Picture2","1"};
List<String> newListObject2 = Arrays.asList(newArray2);
String[] newArray3 = {"Defect Picture3","4"};
List<String> newListObject3 = Arrays.asList(newArray3);
String[] newArray4 = {"Defect Picture4","1"};
List<String> newListObject4 = Arrays.asList(newArray4);
String[] newArray5 = {"Defect Picture5","3"};
List<String> newListObject5 = Arrays.asList(newArray5);
all.add(newListObject1);
all.add(newListObject2);
all.add(newListObject3);
all.add(newListObject4);
all.add(newListObject5);
return all;
}
}
Creating a model as an inner class always works well.
Good way to store any number of items.
public class ActivityClass extends Activity {
...
ArrayList<ValuesModel> listViewValues = new ArrayList<ValuesModel>();
listViewValues.add(new ValuesModel("row title", "row details"));
ListViewAdapter listAdapter = new ListViewAdapter(this, listViewValues);
((ListView) findViewById(android.R.id.list)).setAdapter(listAdapter);
...
public class ValuesModel {
private String rowTitle;
private String rowDetails;
public ValuesModel(String rowTitle, String rowDetails) {
this.rowTitle = rowTitle;
this.rowDetails = rowDetails;
}
public String getRowTitle() {
return rowTitle;
}
public String getRowDetails() {
return rowDetails();
}
}
Then inside of your list adapter,
public class ListViewAdapter extends ArrayAdapter<ActivityClass.ValuesModel> {
private ArrayList<ActivityClass.ValuesModel> mValues;
...
#Override
public View getView(int position, View convertView, ViewGroup parent) {
...
//here whenever you need to retrieve your values, just say:
// mValues.get(position).getRowTitle();
// mValues.get(position).getRowDetails();
//if you use a viewholder pattern, you can do this:
viewHolder.rowTitle = (TextView) convertView.findViewById(R.id.row_title_textview);
viewHolder.rowTitle.setText(mValues.get(position).getRowTitle());
...
}
}
I have an application with three textviews and one checkbox in each row of a listview.what I want that on a click of a button I will be able to get the state of each checkbox and the row corresponding to (isChecked) checkboxes get deleted.one more thing my checkboxes are hardcoded in an xml file.I have searched a lot but couldn't find anything specific.thanks in advance.HERE IS MY CODE...

Try this:
Inside your getView(...) method...
final CheckBox lChk = ((CheckBox) pConvertView.findViewById(R.id.myChkBoxID));
private List<lisInfo> m_lisInfo = new ArrayList<lisInfo>();
lChk.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// Populate the listInfo with check box status
m_lisInfo.get(lPosition).setChkBoxStatus((isChecked));
}
});
public class lisInfo{
private boolean chkBoxStatus;
public boolean isChkBoxStatus() {
return chkBoxStatus;
}
public void setChkBoxStatus(boolean chkBoxStatus) {
this.chkBoxStatus = chkBoxStatus;
}
}
Now iterate the listInfo wherever required to get the check boxes statuses in the list view
maintain an array of boolean inside adapter . set listener on ckeckbox in getview which will swipe values of array on check/uncheck .
now make this array accesible in activity where on button
click()
{
for(int i=0;i<array.size;i++)
{
if(array[i])
adapter.deelet(item i);
//modify syntax
}
}
