Adding Table rows Dynamically in Android

Adding Table rows Dynamically in Android - android

I am trying to create a layout where I need to add table rows dynamically. Below is the table layout xml
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/displayLinear"
android:background="#color/background_df"
android:orientation="vertical" >
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/display_row"
android:layout_marginTop="280dip" >
</TableLayout>
The activity file where rows are being added dynamically is
public void init(){
menuDB = new MenuDBAdapter(this);
ll = (TableLayout) findViewById(R.id.displayLinear);
TableRow row=(TableRow)findViewById(R.id.display_row);
for (int i = 0; i <2; i++) {
checkBox = new CheckBox(this);
tv = new TextView(this);
addBtn = new ImageButton(this);
addBtn.setImageResource(R.drawable.add);
minusBtn = new ImageButton(this);
minusBtn.setImageResource(R.drawable.minus);
qty = new TextView(this);
checkBox.setText("hello");
qty.setText("10");
row.addView(checkBox);
row.addView(minusBtn);
row.addView(qty);
row.addView(addBtn);
ll.addView(row,i);
}
}
But when I run this, I am getting below error
08-13 16:27:46.437: E/AndroidRuntime(23568): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.roms/com.example.roms.DisplayActivity}: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
I understand that this is due to command ll.addView(row,i); but when I remove this its adding all stuff in a single row rather tan creating a new row for next item. I tried with giving index too as row.addView(addBtn,i) but still its not populating correctly. Please advise. Thanks.

Create an init() function and point the table layout.
Then create the needed rows and columns.
public void init() {
TableLayout stk = (TableLayout) findViewById(R.id.table_main);
TableRow tbrow0 = new TableRow(this);
TextView tv0 = new TextView(this);
tv0.setText(" Sl.No ");
tv0.setTextColor(Color.WHITE);
tbrow0.addView(tv0);
TextView tv1 = new TextView(this);
tv1.setText(" Product ");
tv1.setTextColor(Color.WHITE);
tbrow0.addView(tv1);
TextView tv2 = new TextView(this);
tv2.setText(" Unit Price ");
tv2.setTextColor(Color.WHITE);
tbrow0.addView(tv2);
TextView tv3 = new TextView(this);
tv3.setText(" Stock Remaining ");
tv3.setTextColor(Color.WHITE);
tbrow0.addView(tv3);
stk.addView(tbrow0);
for (int i = 0; i < 25; i++) {
TableRow tbrow = new TableRow(this);
TextView t1v = new TextView(this);
t1v.setText("" + i);
t1v.setTextColor(Color.WHITE);
t1v.setGravity(Gravity.CENTER);
tbrow.addView(t1v);
TextView t2v = new TextView(this);
t2v.setText("Product " + i);
t2v.setTextColor(Color.WHITE);
t2v.setGravity(Gravity.CENTER);
tbrow.addView(t2v);
TextView t3v = new TextView(this);
t3v.setText("Rs." + i);
t3v.setTextColor(Color.WHITE);
t3v.setGravity(Gravity.CENTER);
tbrow.addView(t3v);
TextView t4v = new TextView(this);
t4v.setText("" + i * 15 / 32 * 10);
t4v.setTextColor(Color.WHITE);
t4v.setGravity(Gravity.CENTER);
tbrow.addView(t4v);
stk.addView(tbrow);
}
}
Call init function in your onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
init();
}
Layout file like:
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#3d455b"
android:layout_alignParentLeft="true" >
<HorizontalScrollView
android:id="#+id/hscrll1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TableLayout
android:id="#+id/table_main"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" >
</TableLayout>
</RelativeLayout>
</HorizontalScrollView>
</ScrollView>
Will look like:

You shouldn't be using an item defined in the Layout XML in order to create more instances of it. You should either create it in a separate XML and inflate it or create the TableRow programmaticaly. If creating them programmaticaly, should be something like this:
public void init(){
TableLayout ll = (TableLayout) findViewById(R.id.displayLinear);
for (int i = 0; i <2; i++) {
TableRow row= new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(lp);
checkBox = new CheckBox(this);
tv = new TextView(this);
addBtn = new ImageButton(this);
addBtn.setImageResource(R.drawable.add);
minusBtn = new ImageButton(this);
minusBtn.setImageResource(R.drawable.minus);
qty = new TextView(this);
checkBox.setText("hello");
qty.setText("10");
row.addView(checkBox);
row.addView(minusBtn);
row.addView(qty);
row.addView(addBtn);
ll.addView(row,i);
}
}

You also can, as Fredigato said, declare a RelativeLayout in a separate Layout file. Then instantiate it using:
for(int i = 0; i < 6; i ++){
LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout row = (RelativeLayout) inflater.inflate(R.layout.table_view,null);
quizesTableLayout.addView(row,i);
}
In this approach you can easily design one custom row using XML and reuse it.
Now, to be able to change the children views in the instantiated RelativeLayout. You can call row.childAt(index).
So lets say you have a TextView in the RelativeLayout, you can use:
TextView tv = (TextView) row.childAt(0);
tv.setText("Text");

change code of init like following,
public void init(){
menuDB = new MenuDBAdapter(this);
ll = (TableLayout) findViewById(R.id.displayLinear);
ll.removeAllViews()
for (int i = 0; i <2; i++) {
TableRow row=(TableRow)findViewById(R.id.display_row);
checkBox = new CheckBox(this);
tv = new TextView(this);
addBtn = new ImageButton(this);
addBtn.setImageResource(R.drawable.add);
minusBtn = new ImageButton(this);
minusBtn.setImageResource(R.drawable.minus);
qty = new TextView(this);
checkBox.setText("hello");
qty.setText("10");
row.addView(checkBox);
row.addView(minusBtn);
row.addView(qty);
row.addView(addBtn);
ll.addView(row,i);
}

Activity
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<TableLayout
android:id="#+id/mytable"
android:layout_width="match_parent"
android:layout_height="match_parent">
</TableLayout>
</HorizontalScrollView>
Your Class
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_testtable);
table = (TableLayout)findViewById(R.id.mytable);
showTableLayout();
}
public void showTableLayout(){
Date date = new Date();
int rows = 80;
int colums = 10;
table.setStretchAllColumns(true);
table.bringToFront();
for(int i = 0; i < rows; i++){
TableRow tr = new TableRow(this);
for(int j = 0; j < colums; j++)
{
TextView txtGeneric = new TextView(this);
txtGeneric.setTextSize(18);
txtGeneric.setText( dateFormat.format(date) + "\t\t\t\t" );
tr.addView(txtGeneric);
/*txtGeneric.setHeight(30); txtGeneric.setWidth(50); txtGeneric.setTextColor(Color.BLUE);*/
}
table.addView(tr);
}
}

You can use an inflater with TableRow:
for (int i = 0; i < months; i++) {
View view = getLayoutInflater ().inflate (R.layout.list_month_data, null, false);
TextView textView = view.findViewById (R.id.title);
textView.setText ("Text");
tableLayout.addView (view);
}
Layout:
<TableRow
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_centerInParent="true"
android:gravity="center_horizontal"
android:paddingTop="15dp"
android:paddingRight="15dp"
android:paddingLeft="15dp"
android:paddingBottom="10dp"
>
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18sp"
android:gravity="center"
/>
</TableRow>

public Boolean addArtist(String artistName){
SQLiteDatabase db= getWritableDatabase();
ContentValues data=new ContentValues();
data.put(ArtistMaster.ArtistDetails.COLUMN_ARTIST_NAME,artistName);
long id = db.insert(ArtistMaster.ArtistDetails.TABLE_NAME,null,data);
if(id>0){
return true;
}else{
return false;
}
}

I am trying the above code with modification as per my requirement. The table is created properly. Bu the problem is when I am opening the activity 1st time, the table is not displaying. It is displaying 2nd time only.
My code is
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getSupportActionBar().hide();
setContentView(R.layout.activity_aggre_ascendingorder);
drawerLayout = findViewById(R.id.drawer_layout);
init();
}
#SuppressLint("ResourceType")
public void init() {
stk = (TableLayout) findViewById(R.id.table_main);
TableRow tbrow0 = new TableRow(this);
TextView tv0 = new TextView(this);
tv0.setText("Actual Values ");
tv0.setWidth(330);
tv0.setGravity(Gravity.CENTER);
tv0.setTextColor(Color.WHITE);
tv0.setTextSize(12);
tv0.setBackgroundResource(R.drawable.border4);
tbrow0.addView(tv0);

}
//t1v.setText(stb.split(",")[0]);

Try giving layout params to every row you add dynamically and update your init() function like below:

With the below code i could able to create just one question and one radio button, i want to make it dynamic in the future
private void creatRadioButtons() {
group = new RadioGroup(this.getContext());
// group = (RadioGroup) view.findViewById(R.id.radioGroup);
int[] panels = getResources().getIntArray(R.array.no_of_solar_panels);
int no_of_que = 2;
for(int i = 0; i < no_of_que; i++){
// textView = (TextView) view.findViewById(R.id.question);
textView = new TextView(this.getContext());
textView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
textView.setText("Question number " + i);
linearLayout.addView(textView);
for (int j = 0; j< panels.length; j++){
button = new RadioButton(this.getContext());
button.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
button.setText(String.valueOf(panels[j]));
group.setLayoutParams(new RadioGroup.LayoutParams(RadioGroup.LayoutParams.WRAP_CONTENT, RadioGroup.LayoutParams.WRAP_CONTENT));
group.addView(button);
}
linearLayout.addView(group);
}
}

Output As Your Requirement :

You should use RecyclerView instead of just adding fix number of question at design time,via RecyclerView you can add as much as question you want dynamically.

You need to use recyclerview to create dynamic no. of questions. In recycler layout, create a question with four radio buttons.
For recycler example, see this

How to horizontally align some programmatically added views?

I have designed a layout as in the image below:
After entering text in the EditText, when I press the Add+ Button the TextView and Button will be added as shown in the image below:
I want to show the Button on the right side of the TextView. How should I do this?
Another question, how should I remove corresponding View when user clicks a button? The code:
public class ExampleActivity extends Activity {
private LinearLayout mLayout;
private EditText mEditText;
private Button mButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mLayout = (LinearLayout) findViewById(R.id.linearLayout);
mEditText = (EditText) findViewById(R.id.editText);
mButton = (Button) findViewById(R.id.button);
mButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mLayout.addView(createNewTextView(mEditText.getText()
.toString()));
mLayout.addView(createNewButton());
}
});
}
private TextView createNewTextView(String text) {
final LayoutParams lparams = new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
final TextView textView = new TextView(this);
textView.setLayoutParams(lparams);
textView.setText("New text: " + text);
return textView;
}
private Button createNewButton() {
final LayoutParams lparams = new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
final Button button = new Button(this);
button.setLayoutParams(lparams);
button.setText(" - ");
return button;
}
}

The TextViews and Buttons are stacked because you probably use a LinearLayout with the orientation vertical. You could wrap your TextView + Button into a LinearLayout and then add this LinearLayout to your own layout or you could use a TableLayout like below(I've added some ids so you can delete the rows you want):
public class SomeActivity extends Activity {
private EditText mInput;
private TableLayout mTable;
private static int sCount = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button addButton = (Button) findViewById(R.id.add);
mInput = (EditText) findViewById(R.id.editText1);
mTable = (TableLayout) findViewById(R.id.table1);
addButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mTable.addView(addRow(mInput.getText().toString()));
}
});
}
private TableRow addRow(String s) {
TableRow tr = new TableRow(this);
tr.setId(1000 + sCount);
tr.setLayoutParams(new TableLayout.LayoutParams(
TableLayout.LayoutParams.FILL_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT));
TableRow.LayoutParams tlparams = new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT);
TextView textView = new TextView(this);
textView.setLayoutParams(tlparams);
textView.setText("New text: " + s);
tr.addView(textView);
TableRow.LayoutParams blparams = new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT);
final Button button = new Button(this);
button.setLayoutParams(blparams);
button.setText(" - ");
button.setId(2000 + sCount);
button.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
mTable.removeView(findViewById(v.getId() - 1000));
}
});
tr.addView(button);
sCount++;
return tr;
}
}
where the main layout file is:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="#+id/parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/add"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TableLayout
android:id="#+id/table1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TableLayout>
</LinearLayout>
</ScrollView>
If for some reason, you don't like the TableLayout use a LinearLayout to wrap you TextView and Button with the layout file above(and of course remove the TableLayout):
//...
ll = (LinearLayout) findViewById(R.id.parent);
addButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//where ll is the LinearLayout with the id parent
ll.addView(addRow(mInput.getText().toString()));
}
});
}
private LinearLayout addRow(String s) {
LinearLayout tr = new LinearLayout(this);
tr.setId(1000 + sCount);
tr.setLayoutParams(new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
LinearLayout.LayoutParams tlparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
TextView textView = new TextView(this);
textView.setLayoutParams(tlparams);
textView.setText("New text: " + s);
tr.addView(textView);
LinearLayout.LayoutParams blparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
final Button button = new Button(this);
button.setLayoutParams(blparams);
button.setText(" - ");
button.setId(2000 + sCount);
button.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
ll.removeView(findViewById(v.getId() - 1000));
}
});
tr.addView(button);
sCount++;
return tr;
}

LinearLayout having the property Orientation to align control either Vertically/Horizontally
so just set Orientation of the same
http://developer.android.com/reference/android/widget/LinearLayout.html
mLayout = (LinearLayout) findViewById(R.id.linearLayout);
mLayout.setOrientation(LinearLayout.HORIZONTAL);

How an Edit Text can be created dynamically in Android

I am new to android programming and I have a problem of creating text fields dynamically;
I want to create a view in which there is a button named "Create text fields" and two Edit Text one Edit Text name is ROW and the second edit text name is COLUMN. As a user enters numbers in the both Edit Text let say ROW =2 and COLUMN =3 and press the button "Create text fields" it may create 6 Edit Text below the button of "Create text fields". These 6-edit text should be positioned in 2 rows and 3 columns like below
EditText-1 EditText-2 EditText-3
EditText-1 EditText-2 EditText-3

setContentView(R.layout.main);
LinearLayout ll = (LinearLayout)findViewById(R.id.ll);
Display display = ((WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int width = display.getWidth()/3;
for(int i=0;i<2;i++){
LinearLayout l = new LinearLayout(this);
l.setOrientation(LinearLayout.HORIZONTAL);
for(int j=0;j<3;j++){
EditText et = new EditText(this);
LayoutParams lp = new LayoutParams(width,LayoutParams.WRAP_CONTENT);
l.addView(et,lp);
}
ll.addView(l);
}
use the above code in your onCreate() where "main" is xml file. and you can replace i<2 and j<3 with values of edittext 1 & 2.
sample main.xml which i am using is below::
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ll"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/et1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<requestFocus />
</EditText>
<EditText
android:id="#+id/et2"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>

public class DynamicEditTextActivity extends Activity {
private EditText row, column;
private Button submit;
private LinearLayout main, matrix;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
main = (LinearLayout) findViewById(R.id.mainlayout);
row = (EditText) findViewById(R.id.row);
column = (EditText) findViewById(R.id.column);
matrix = (LinearLayout) findViewById(R.id.matrix);
matrix.setOrientation(LinearLayout.VERTICAL);
submit = (Button) findViewById(R.id.submit);
submit.setOnClickListener(generate);
}
OnClickListener generate = new OnClickListener() {
public void onClick(View v) {
matrix.removeAllViews();
int rows = Integer.parseInt(row.getText().toString());
int cols = Integer.parseInt(column.getText().toString());
for (int i = 0; i < rows; i++) {
LinearLayout layout = new LinearLayout(
DynamicEditTextActivity.this);
layout.setOrientation(LinearLayout.HORIZONTAL);
for (int j = 0; j < cols; j++) {
TextView text = new TextView(DynamicEditTextActivity.this);
text.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
text.setText((j+1) + " ");
text.setTextColor(Color.RED);
layout.addView(text);
}
matrix.addView(layout);
}
}
};

This is how you create an EditText box dynamically...
Hope this is useful...
This is just an example... You can reference this...
EditText t = new EditText(myContext);
t.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
layout.addView(t);
final LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
final EditText edit_text = new EditText(this);
edit_text.setLayoutParams(lparams);
edit_text.setText("New text: " + text);

try like this function
public static void display(final Activity activity, Button btn) {
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
LinearLayout scrollViewlinerLayout = activity.findViewById(R.id.linearLayoutForm);
java.util.ArrayList<String> msg = new ArrayList<String>();
for (int i = 0; i < scrollViewlinerLayout.getChildCount(); i++)
{
LinearLayout innerLayout = (LinearLayout) scrollViewlinerLayout.getChildAt(i);
EditText edit = innerLayout.findViewById(R.id.editDescricao);
msg.add(edit.getText().toString().trim());
int childcount = scrollViewlinerLayout.getChildCount();
for( i =0 ; i < childcount; i++){
View view = scrollViewlinerLayout.getChildAt(i);
}
}
Toast t = Toast.makeText(activity.getApplicationContext(), msg.toString(), Toast.LENGTH_SHORT);
t.show();
}
}); }

TableLayout binding problem at runtime?

I've arraylist of objects and i need to bind these list of objects to TableLayout at runtime but i didn't get any data into it, please check my code:
XML code:
<TableLayout android:background="#cfe1edFF" android:id="#+id/tl"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TableRow>
<TextView android:text="Symbol"
android:layout_height="fill_parent" android:textColor="#104e8b"
android:layout_width="wrap_content"
android:layout_weight="1" android:gravity="center" android:background="#drawable/shapefile"/>
<TextView android:text="A/c Type"
android:layout_height="fill_parent" android:textColor="#104e8b"
android:layout_width="wrap_content"
android:layout_weight="1" android:gravity="center" android:background="#drawable/shapefile">
</TextView>
<TextView android:text="Position" android:textColor="#104e8b" android:layout_height="fill_parent"
android:layout_width="wrap_content"
android:layout_weight="1" android:gravity="center" android:background="#drawable/shapefile">
</TextView>
</TableRow>
<ScrollView>
<TableLayout android:id="#+id/score_table"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableRow></TableRow>
</TableLayout>
</ScrollView>
</TableLayout>
so from above TableLayout "score_table" i'm trying to bind data from ArrayList of objects like:
Code to bind table layout using arryalist objects:
public void TableBinding(ArrayList<Position> posLst)
{
TableLayout tLayout=(TableLayout)findViewById(R.id.score_table);
Position pos;
for(int i=0;i<posLst.size();i++)
{
TableRow tr = new TableRow(this);
tr.setId(100+i);
pos=posLst.get(i);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView b = new TextView(this);
b.setText(pos.Symbol);
tr.addView(b);
//b.setId(200+i);
TextView b1 = new TextView(this);
b1.setText(pos.AcType);
tr.addView(b1);
//b1.setId(300+i);
TextView b2 = new TextView(this);
b2.setText(pos.Position);
tr.addView(b2);
//b2.setId(400+i);
/* Add row to TableLayout. */
tLayout.addView(tr,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
}
But i didn't get any data into it, i already checked that ArrayList getting data, please help me.
Thanks,
nag.

You try this way :
ArrayList<String> tablesName = new ArrayList<String>();
TableLayout tl;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tl = (TableLayout) findViewById(R.id.tableLayout1);
for (int i = 0; i < posLst.size(); i++) {
TableRow tr = new TableRow(this);
CheckBox ch = new CheckBox(this);
ch.setId(i);
TextView tv2 = new TextView(this);
tr.addView(ch);
createView(tr, tv2, tablesName.get(i));
tl.addView(tr);
}
public void createView(TableRow tr, TextView t, String viewdata) {
t.setText(viewdata);
t.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
t.setTextColor(Color.DKGRAY);
t.setPadding(20, 0, 0, 0);
tr.setPadding(0, 1, 0, 1);
tr.addView(t);
}

try this it worked for me
for (int position=0; position < data.size(); position++)
{
TableRow tableRow= new TableRow(this);
ArrayList<Object> row = data.get(position);
TextView idText = new TextView(this);
idText.setText(pos.Symbol);
tableRow.addView(idText);
TextView textOne = new TextView(this);
textOne.setText(pos.AcType);
tableRow.addView(textOne);
TextView textTwo = new TextView(this);
textTwo.setText(pos.AcType);
tableRow.addView(textTwo);
dataTable.addView(tableRow);
}
}
