Having difficulty in getting dynamically added table rows to show up

I am working on a screen that basically shows questions and answers in a grid format and I am putting them all into table rows dynamically. The problem I am having is that once I put in the first row (the header), the rest of the rows in the table do not show up. I first add the headers. This shows up.
protected void setupTableHeaders() {
TableRow tableRow = getNewTableRow();
tableRow.setTag(header);
TextView textView = new TextView(this);
GlobalVars.setupText(this,textView,32320); //Event
textView.setTextColor(R.color.black);
LayoutParams params = new LayoutParams(0,LayoutParams.WRAP_CONTENT,3.0f);
params.setMarginStart(50);
tableRow.addView(textView,params);
tableRow.addView(getNewDivider(),(new LayoutParams(0,LayoutParams.WRAP_CONTENT,.1f)));
Iterator it = mapQuestions.entrySet().iterator();
//first get all the answers
if (it.hasNext()) {
Map.Entry pair = (Map.Entry) it.next();
HolderQuestion holderQuestion = mapQuestions.get(pair.getKey());
//assume all answers sets for all questions on this screen are the same.
int i = 0;
for (HolderAnswer answer : holderQuestion.getListAnswers()) {
TextView textViewHeader = new TextView(this);
textViewHeader.setTextColor(R.color.black);
GlobalVars.setupText(this, textViewHeader, answer.getTextID());
tableRow.addView(textViewHeader, (new LayoutParams(0, LayoutParams.WRAP_CONTENT, .5f)));
if (i < holderQuestion.getListAnswers().size() - 1) {
tableRow.addView(getNewDivider(), (new LayoutParams(0, LayoutParams.WRAP_CONTENT, .1f)));
}
i++;
}
}
table1.addView(tableRow);
}
Then I add the questions and answers, which do not show up:
protected void setupRadioButtonAnswers() {
for (int i=0;i<holderQuestionMultis.size();i++) { //assume this is populated correctly
TableRow tableRow = getNewTableRow();
tableRow.setTag(answerRow);
TextView textView = new TextView(this);
textView.setTextColor(R.color.black);
GlobalVars.setupText(this,textView,holderQuestionMultis.get(i).getHolderQuestion().getTextID());
textView.setTag(textCell);
textView.setVisibility(View.VISIBLE);
LayoutParams params = new LayoutParams(0,LayoutParams.WRAP_CONTENT,3.0f);
params.leftMargin = 50;
tableRow.addView(textView,params);
tableRow.addView(getNewDivider(),(new LayoutParams(0,LayoutParams.WRAP_CONTENT,.1f)));
for (int j=0;j<holderQuestionMultis.get(i).getRadioButtons().size();j++) {
RadioButton radioButton = holderQuestionMultis.get(i).getRadioButtons().get(j);
radioButton.setVisibility(View.VISIBLE);
tableRow.addView(radioButton,(new LayoutParams(0,LayoutParams.WRAP_CONTENT,.5f)));
if (j< holderQuestionMultis.size()-1) {
tableRow.addView(getNewDivider(),(new LayoutParams(0,LayoutParams.WRAP_CONTENT,.1f)));
}
}
tableRow.setVisibility(View.VISIBLE);
table1.addView(tableRow);
}
}
And the two methods which get the radioButtons and table rows:
// table elements
protected TableRow getNewTableRow() {
TableRow tableRow = new TableRow(this);
TableLayout.LayoutParams tlparams = new TableLayout.LayoutParams(
TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT);
tableRow.setBackground(getResources().getDrawable(R.drawable.border_table_multi_grid));
tableRow.setLayoutParams(tlparams);
return tableRow;
}
protected RadioButton getRadioButton() {
RadioButton radioButton = new RadioButton(this);
radioButton.setBackground(getResources().getDrawable(R.drawable.radio_button_multigrid));
//radioButton.setButtonDrawable(R.color.transparent);
TableRow.LayoutParams params = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT);
radioButton.setLayoutParams(params);
return radioButton;
}
The tablelayout xml:
<TableLayout
android:id="#+id/table"
android:layout_width="match_parent"
android:layout_height="300dp"
android:orientation="horizontal"
android:layout_above="#+id/viewSpacer"
android:layout_below="#+id/lblSubQuestionText"
android:layout_marginBottom="15dp"
android:layout_marginRight="15dp"
android:layout_marginLeft="15dp"
android:layout_marginTop="15dp"
android:background="#drawable/border_table_multi_grid">
What am I missing? Is the first table header row covering up the other rows? Why do they not appear?

It turns out that this code:
tableRow.addView(getNewDivider(),(new LayoutParams(0,LayoutParams.WRAP_CONTENT,.1f)));
Was the culprit which consisted of adding a LinearLayout containing a view. Just adding the view alone solved the problem.

How to add multiple columns in a row of an android table layout

I have a custom list with name,age and grade .I want to loop through the list and show the contents in a table layout.Each row will have following attributes.Row will have some kind of styling
Name,
Age,
Age_Value,
Grade,
Grade_Value
Here Age and Grades are just a label.Given below is a sample table
Dolly
Age
23
Grade
A+
Roman
Age
22
Grade
C
Ben
Age
23
Grade
B+
I want to add these details to the Table layout in my layout dynamically.
Here is the code im trying
for(int j=0;j<_attributeList.size();j++)
{
TableRow tr = new TableRow(MyActivity.this);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView tvName = new TextView(MyActivity.this);
tvName.setPadding(3,0,0,0);
tvName.setText(_attributeList.get(j).getName() +" : ");
tr.addView(tvName);
TextView tvAgeL = new TextView(MyActivity.this);
tvAgeL .setText("Age");
tr.addView(tvAgeL );
TextView tvAgeValue = new TextView(MyActivity.this);
tvAgeValue .setPadding(3,0,0,0);
tvAgeValue .setText(_attributeList.get(j).getValue() +" : ");
tr.addView(tvAgeValue );
attributeTable.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
}
Since these items are adding to the same row im getting results in a single line. How can i show them in seperate rows

You should try like this
Code
for(int i = 0; i < _attributeList.size();i++){
TableRow newRow = new TableRow(getApplicationContext());
newRow.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
newCheckBox = new CheckBox(getApplicationContext());
TextView feeTypeText = new TextView(getApplicationContext());
feeTypeText.setText(jsonObj.getString("feeType"));
feeTypeText.setTextColor(Color.BLACK);
feeTypeText.setTextSize(16f);
feeTypeText.setTypeface(tf);
TextView dueAmountText = new TextView(getApplicationContext());
dueAmountText.setText(jsonObj.getString("dueAmount"));
dueAmountText.setTextColor(Color.BLACK);
dueAmountText.setTextSize(16f);
dueAmountText.setTypeface(tf);
TextView dueDateText = new TextView(getApplicationContext());
dueDateText.setText(jsonObj.getString("dueDate"));
dueDateText.setTextColor(Color.BLACK);
dueDateText.setTextSize(16f);
dueDateText.setTypeface(tf);
newRow.addView(newCheckBox,(new LayoutParams(0,LayoutParams.WRAP_CONTENT,0.8f)));
newRow.addView(feeTypeText,(new LayoutParams(0,LayoutParams.WRAP_CONTENT,0.8f)));
newRow.addView(dueAmountText,(new LayoutParams(0,LayoutParams.WRAP_CONTENT,1.0f)));
newRow.addView(dueDateText,(new LayoutParams(0,LayoutParams.WRAP_CONTENT,1.0f)));
attributeTable.addView(newRow);
}

you can add like this way...here i added TableRow Programatically in which i added textView.
addtree.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View arg0)
{
tr1 = new TableRow(YourActivity.this);
tr1.setClickable(true);
tr1.setId(jj);
tr1.setPadding(0, 5, 0, 5);
Log.d("id", "id is......"+tr1.getId());
LinearLayout.LayoutParams layoutParams=new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
TextView textview = new TextView(New_Quote_Activity.this);
textview.setText("Job "+jj);
textview.setTextColor(Color.BLACK);
textview.setTypeface(null, Typeface.BOLD);
textview.setTextSize(14);
textview.setPadding(5, 0, 0, 0);
View vv=new View(New_Quote_Activity.this);
vv.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,1));
vv.setBackgroundResource(R.color.viewcolor);
View vv1=new View(New_Quote_Activity.this);
vv1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,1));
vv1.setBackgroundResource(R.color.viewcolor);
tr1.addView(textview);
table_crete_invoice.addView(vv1);
table_crete_invoice.addView(tr1,layoutParams);
table_crete_invoice.addView(vv);
}

Get Controls/Views from dynamic content Tab

I have created tabs and their content from a database. Now I need help figuring out how to get the user entered values from those controls - how to get a list of the controls on the tabs (so the data can be saved). Here is a condensed sample of how I'm populating the tabs contents:
public View createTabContent(String tag)
{
SQLiteDatabase db2 = openOrCreateDatabase(msDbFile, MODE_PRIVATE, null);
Cursor cList = db2.rawQuery("SELECT * FROM CheckList WHERE CatID=" + tag, null);
TableLayout tl = new TableLayout(FormChecklist.this);
tl.setBackgroundColor(new Color().WHITE);
while(cList.moveToNext())
{
/* Create a new row to be added. */
TableRow tr = new TableRow(FormChecklist.this);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
/* Create the row-content. */
TextView lblQuestion = new TextView(FormChecklist.this);
lblQuestion.setText(cList.getString(2));
lblQuestion.setTag(tag);
/* Add control to row. */
tr.addView(lblQuestion);
CheckBox chkCompleted = new CheckBox(FormChecklist.this);
chkCompleted.setText("Completed");
chkCompleted.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
chkCompleted.setTag(tag);
/* Add control to row. */
tr.addView(chkCompleted);
/* Add row to TableLayout. */
tl.addView(tr,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
db2.close();
return tl;
}

No replies, but finally figured out, hopefully someone will find this info helpful.
Approach I took was modifying my createTabContent adding an ID for the TableLayout:
tl.setId(1000 + miTlCnt);
Then in my save routine I loop through controls like so:
for (int i = 1000 + miTlCnt; i > 1000; i--)
{
TableLayout tl = (TableLayout)findViewById(i);
if (tl != null)
{
for (int j = 0; j < tl.getChildCount(); j++)
{
TableRow row = (TableRow)tl.getChildAt(j);
CheckBox chkCompleted = (CheckBox)row.getChildAt(1);
}
}
}

ANdroid: Dynamicly add Image Buttons to rows in Table Layout

I need to add a number of rows to my Table layout and to each row I need to add two Image Buttons. Number of rows can be different each time I start the Activity - I look into a SQLite database and for each row in the database I need to add an Image Button. And there will be two Image Buttons in each row of Table layout. So far, I have this code:
db.open();
int count = db.getCount();
boolean newRow = true;
for (int i = 0; i < count; i++) {
if (newRow == true) {
newRow = false;
row = new TableRow(this);
row.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
}
ImageButton button = new ImageButton(this);
row.addView(button);
tableLayout.addView(row);
}
db.close();
TableRow row is defined above this block of code simply as variable for this Activity. My Table layout (tableLayout in code) is defined in XML code of the Activity layout:
<TableLayout
android:id="#+id/tableLayoutContacts"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TableLayout>
The code crashes at the line
tableLayout.addView(row);
I wasnt able to resolve this. Any ideas? Thanks!!

I think the problem is different
It seems that Your code will have only one row and you are adding that row again and again to tableLayout as shown below.
tableLayout.addView(row);
This will lead to IllegalStateException at addViewInner Function of ViewGroup
try this
db.open();
int count = db.getCount();
boolean newRow = false;
for (int i = 0; i < count; i++) {
if (i % 2 == 0)
newRow = true;
if (newRow == true) {
newRow = false;
row = new TableRow(this);
row.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
tableLayout.addView(row);
}
ImageButton button = new ImageButton(this);
row.addView(button);
}
db.close();

Android - Adding layout at runtime to main layout

I am trying to add a tableLayout at runtime to the existing LinearLayout in main.xml.
I have added a editText(R.id.editText1) in the main.xml. Here's my code. Its not working. I get a runtime error (The application has stopped unexpectedly).
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
text = (EditText)findViewById(R.id.editText1);
TableLayout tblLayout = new TableLayout(this);
tblLayout.setLayoutParams(new TableLayout.LayoutParams(8,5));
tblLayout.setPadding(1,1,1,1);
for(int r=0; r<ROW_COUNT; ++r)
{
TableRow tr = new TableRow(this);
for(int c=0; c<COL_COUNT; ++c)
{
int index = r * COL_COUNT + c;
buttonList.add(new Button(this));
buttonList.get(index).setText(buttonNames[index]);
tr.addView(buttonList.get(index), 60, 30);
}
tblLayout.addView(tr);
}
LinearLayout mainLayout = (LinearLayout)findViewById(R.layout.main);
mainLayout.addView(tblLayout);
setContentView(mainLayout);
}
Any pointers would be greatly appreciated. Thanks.

Before your loop add :
Arraylist<TableRow> tr = new ArrayList<TableRow>;
In the loop instead of :
TableRow tr = new TableRow(this);
Put :
tr.add(new TableRow(this));
And finally replace your tr by tr.get(r). Something like these modifications should help you because, you erase your tr at each turn of your loop with your :
TableRow tr = new TableRow(this);

Mr. Happy Go Lucky just do one thing write setContentView(R.layout.your Main Layout); beofre text = (EditText)findViewById(R.id.editText1);
means at top of the onCreate() method because we cant define any view before setContentView.
without any setContentView you cant find any view like as findViewById(R.id.editText1);

Below line will be the first one after super.onCreate(savedInstanceState);
setContentView(mainLayout);
then only findViewByid works
