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

public void init() {

tbrow0.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,

tv0.setTextColor(Color.WHITE);
//added layout params and weight

And provide android:fillViewport="true" to your ScrollView with id=scrollView1 and HorizontalScrollView with id=hscrll1

extend tablerow view

I am trying to programmatically create this xml view by extending tablerow view:
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="center_vertical"
android:weightSum="1.0" >
<Button
android:id="#+id/tester_button"
style="?android:attr/buttonStyleSmall"
android:layout_weight=".2"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:text="A" />
<TextView
android:id="#+id/textView2"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:gravity="center"
android:layout_weight=".7"
android:text="Column 1"
android:textAppearance="?android:attr/textAppearanceLarge" />
<CheckBox
android:id="#+id/checkBox1"
android:layout_weight=".1"
android:layout_width="0dip"
android:layout_height="wrap_content" />
</TableRow>
This is my class of the extended row:
public class CategoryRow extends TableRow {
LayoutParams rowParams = new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.CENTER);
LayoutParams innerParams = new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, Gravity.CENTER);
CheckBox check;
Button arrowButton;
TextView categoryTitle;
public CategoryRow(Context context) {
super(context);
this.setLayoutParams(rowParams);
this.setGravity(Gravity.CENTER);
this.setWeightSum(1);
check = new CheckBox(context);
innerParams.weight = (float) 0.1;
check.setLayoutParams(innerParams);
arrowButton = new Button(context);
innerParams.weight = (float) 0.2;
arrowButton.setLayoutParams(innerParams);
arrowButton.setText("A");
categoryTitle = new TextView(context);
innerParams.weight = (float) 0.7;
categoryTitle.setLayoutParams(innerParams);
categoryTitle.setTextAppearance(context, android.R.attr.textAppearanceLarge);
//add views to row
this.addView(arrowButton);
this.addView(categoryTitle);
this.addView(check);
}
public void setCategoryTitle(String title){
categoryTitle.setText(title);
}
public void checkCategory(){
check.setChecked(true);
}
public void unCheckCategory(){
check.setChecked(false);
}
}
in my activity I am adding the CategoryRow view to the TableLayout by addView function.
public class NotificationCategorise extends Activity {
TableLayout categoryConteiner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification_categorise);
categoryConteiner = (TableLayout) findViewById(R.id.categories_conteiner);
CategoryRow categoryRow = new CategoryRow(this);
categoryRow.setCategoryTitle("bla");
categoryConteiner.addView(categoryRow);
}
My problem is that it the CategoryRow not added to the activity sceen.

I have changed the extended class to this code, and it worked fine.
import android.content.Context;
import android.view.Gravity;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.TableRow;
import android.widget.TextView;
public class CategoryRow extends TableRow {
LayoutParams rowParams = new TableRow.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
LayoutParams innerParams1 = new TableRow.LayoutParams(0, LayoutParams.MATCH_PARENT, Gravity.CENTER);
LayoutParams innerParams2 = new TableRow.LayoutParams(0, LayoutParams.MATCH_PARENT, Gravity.CENTER);
LayoutParams innerParams3 = new TableRow.LayoutParams(0, LayoutParams.MATCH_PARENT, Gravity.CENTER);
CheckBox check;
Button arrowButton;
TextView categoryTitle;
public CategoryRow(Context context) {
super(context);
this.setLayoutParams(rowParams);
this.setWeightSum(1f);
check = new CheckBox(context);
innerParams1.weight = 0.1f;
check.setLayoutParams(innerParams1);
arrowButton = new Button(context);
innerParams2.weight = 0.2f;
arrowButton.setLayoutParams(innerParams2);
arrowButton.setText("A");
categoryTitle = new TextView(context);
categoryTitle.setGravity(Gravity.CENTER);
innerParams3.weight = 0.7f;
categoryTitle.setLayoutParams(innerParams3);
categoryTitle.setTextAppearance(context, android.R.attr.textAppearanceLarge);
//add views to row
this.addView(arrowButton);
this.addView(categoryTitle);
this.addView(check);
}
public void setCategoryTitle(String title){
categoryTitle.setText(title);
}
public void checkCategory(){
check.setChecked(true);
}
public void unCheckCategory(){
check.setChecked(false);
}
}

Ok, I don't think you can pass in the GRAVITY.CENTER as an argument for the LayoutParams constructor for the row. You change it for each individual View added to the row, but not for the row itself. Change:
LayoutParams rowParams = new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.CENTER);
to
LayoutParams rowParams = new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
See if that works.

dynamically creating tablelayout (android)

I want to create inner tablelayout and add there 1 row with 2 columns, following code shows nothing, why?
Here's main activity:
public class TestActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
TextView tv1 = new TextView(this);
TextView tv2=new TextView(this);
tv1.setLayoutParams(params);
tv2.setLayoutParams(params);
tv1.setText("Hello1!");
tv2.setText("Hello2!");
TableLayout layoutINNER = new TableLayout(this);
layoutINNER.setLayoutParams(params);
TableRow tr = new TableRow(this);
tr.setLayoutParams(params);
tr.addView(tv1);
tr.addView(tv2);
layoutINNER.addView(tr);
LinearLayout main = (LinearLayout)findViewById(R.id.android_main_layout);
main.addView(layoutINNER);
}
}
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/android:main_layout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
</LinearLayout>
UPDATE:
Well, finally i solved this problem, it was just needed to use TableRow.LayoutParams with TextViews, not LinearLayout.LayoutParams or some other

Here is the working code:
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class TestActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
TextView tv1 = new TextView(this);
TextView tv2=new TextView(this);
android.widget.TableRow.LayoutParams trparams = new TableRow.LayoutParams(android.widget.TableRow.LayoutParams.WRAP_CONTENT, android.widget.TableRow.LayoutParams.WRAP_CONTENT);
tv1.setLayoutParams(trparams);
tv2.setLayoutParams(trparams);
tv1.setText("Hello1!");
tv2.setText("Hello2!");
TableLayout layoutINNER = new TableLayout(this);
layoutINNER.setLayoutParams(params);
TableRow tr = new TableRow(this);
tr.setLayoutParams(params);
tr.addView(tv1);
tr.addView(tv2);
layoutINNER.addView(tr);
LinearLayout main = (LinearLayout)findViewById(R.id.android_main_layout);
main.addView(layoutINNER);
}
}

My problem is that i am able to see both text and image in all the four sections, whereas i want to display text only in first two sections and image in other two sections.
Can anybody tell me that what i am doing wrong?
Thanks,

Your problem is simple.
You are inflating a view in the
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent)
method of your adapter.
However this inflated view contains both a text view and an image view. If you only want to display one, you need to hide the other.
if (groupPosition == 0)
{
// set your text hide
// HIDE YOUR IMAGE VIEW
ImageView iv = ...
iv.setVisibility(View.GONE);
}
...
if (groupPosition == 3)
{
// set your image source
// HIDE YOUR TEXT VIEW
TextView tv = ...
t.setVisibility(View.GONE);
}
That should solve your problem and you should be able to finish it from here :)
