Android XML vs code tablelayout differences

I want to use code to generate a very large TableLayout. XML works great but the file is getting huge and making changes would be tedious down the road. The final layout will have a HorizontalScrollview on the right but my problem is best illustrated as follows.
The XML file is this.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<TableLayout
android:layout_width="wrap_content"
android:layout_height="match_parent">
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Table 1"/></TableRow>
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Table 1"/></TableRow>
</TableLayout>
<TableLayout
android:layout_width="wrap_content"
android:layout_height="match_parent">
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Table 2"/></TableRow>
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Table 2"/></TableRow>
</TableLayout>
</LinearLayout>
this outputs like this (sorry, can't post screenshot)
Table 1 Table 2
Table 1 Table 2
When I use code this this
LinearLayout ll = new LinearLayout(this);
ll.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
TableLayout table1 = new TableLayout(this);
table1.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.MATCH_PARENT));
for (int x = 0;x < 2;x++) {
TableRow row = new TableRow(this);
row.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT));
TextView tv = new TextView(this);
tv.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT));
tv.setText("Table 1");
row.addView(tv);
table1.addView(row);
}
TableLayout table2 = new TableLayout(this);
table2.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.MATCH_PARENT));
for (int x = 0;x < 2;x++) {
TableRow row = new TableRow(this);
row.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT));
TextView tv = new TextView(this);
tv.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT));
tv.setText("Table 2");
row.addView(tv);
table2.addView(row);
}
ll.addView(table1);
ll.addView(table2);
setContentView(ll);
it shows output like
Table 1
Table 1
I lose the second tablelayout. How can I change the code style to view that second tablelayout?

I didn't find out why the second table doesn't work in code but I was able to fix my problem by
Setting up the LinearLayout and the TableLayouts in XML.
Then referencing the TableLayouts and adding the TableRows in code.

my table dynamic layout keep appearing in the left side even the gravity is right

what i am trying to do is to make a dynamic table layout .. i mean the rows will be filled dynamically with text views and with scrolling horizontal and vertical but each time when the activity open my table layout start showing from the left side even i set the gravity to be right .. why this is happening?
this is my xml code :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right" >
<HorizontalScrollView
android:id="#+id/horizontalScrollView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TableLayout
android:id="#+id/table1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:stretchColumns="0,1"
android:layout_gravity="right" >
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right"
android:layout_gravity="right">
</TableRow>
</TableLayout>
</ScrollView>
</HorizontalScrollView>
</LinearLayout>
and here is my java code :
TableLayout ll = (TableLayout) findViewById(R.id.table1);
int razan=0;
int c=-1;
for(int s=1; s<=fixed;s++){
if(razan<=count){
for (int i = 0; i <text.length; i++) {
if(i>0 && i%7==0){
c = c+1;
TableRow row1= new TableRow(this);
TableRow.LayoutParams tr1 = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
row1.setLayoutParams(tr1);
TextView emptyrow = new TextView(this);
emptyrow.setText("");
// emptyrow.setBackground(getResources().getDrawable(R.drawable.back));
row1.addView(emptyrow);
ll.addView(row1,i);
}
TableRow row= new TableRow(this);
TableRow.LayoutParams tr = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(tr);
TextView product = new TextView(this);
TextView product_j = new TextView(this);
product_j.setText(prodlist.get(razan));
Resources res = getResources();
Drawable drawable = res.getDrawable(R.drawable.back);
product_j.setBackgroundDrawable(drawable);
product_j.setGravity(Gravity.RIGHT);
product_j.setTextSize(18);
product.setText(text[i]);
// product.setBackgroundDrawable(drawable);
product.setGravity(Gravity.RIGHT);
product.setPadding(3, 0, 3, 0);
product.setTextSize(18);
row.addView(product_j);
row.addView(product);
razan++;
ll.addView(row,i);
//here is the code for adding an empty row after each seven inner rows !!!
}//inner for
}
}//outer fors
}
can anyone help me?

Make your root LinearLayouts Height and width as match_parent and try gravity to right on your TableLayout

TextView displaying text in One line when adding rows programatically in Table Layout

I have a table layout after some view in my xml file. Below is the code.
<ScrollView>
<LinearLayout>
..................................
.....................................
<Button
android:id="#+id/fetchbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="show details"
android:layout_margin="6dip"
android:layout_gravity="center_horizontal"
android:onClick="buttonOnClick"/>
<TableLayout
android:id="#+id/mytable_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:orientation="vertical"
>
</TableLayout>
</LinearLayout>
</ScrollView>
Below is the code to add the rows programatically for a table layout:
public void buttonOnClick(View view)
{
showData();
}
public void showData()
{
List<DataSource> data = dbHelper.getData(selectedoption);
TableLayout tl = (TableLayout)findViewById(R.id.mytable_layout);
for(DataClass dataclass:data)
{
TableRow tr = new TableRow(ViewScreen.this);
TableRow.LayoutParams params = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(params);
TextView labelTV = new TextView(ViewScreen.this);
labelTV.setText(dataclass.getColumnName());
labelTV.setTextColor(Color.RED);
TableRow.LayoutParams paramsTV1 = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
labelTV.setLayoutParams(paramsTV1);
tr.addView(labelTV);
// Creating a TextView to house the value of the after-tax income
TextView valueTV = new TextView(ViewScreen.this);
valueTV.setText(dataclass.getColumnValue());
valueTV.setTextColor(Color.BLACK);
TableRow.LayoutParams paramsTV2 = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
valueTV.setLayoutParams(paramsTV2);
tr.addView(valueTV);
// Adding the TableRow to the TableLayout
tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
}
}
So as per the above code, it's working fine. But the table row is always with one line. The table row height is not increased according to the content. Instead the part of text goes off screen and invisible. Can some one please help to solve this issue?
Picture:

create a custom single_row.xml as below:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relativeLayoutSingleRowRecordsDetailedView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff" >
<TextView
android:id="#+id/textViewSingleRowRecordsDetailedViewCategoryField"
android:layout_width="120dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="10dp"
android:text="TextView"
android:textColor="#04B4AE"
android:textSize="15dp"
android:typeface="sans" />
<TextView
android:id="#+id/textViewSingleRowRecordsDetailedViewCategoryFieldValue"
android:layout_width="120dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginRight="10dp"
android:text="TextView"
android:textColor="#000000"
android:textSize="15dp"
android:typeface="sans" />
</RelativeLayout>
And then in my java code:
...
LayoutInflater inflate = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View view = inflate.inflate(R.layout.single_row_records_detailed_view, null);
TextView tv_field_name = (TextView) view.findViewById(R.id.textViewSingleRowRecordsDetailedViewCategoryField);
TextView tv_field_value = (TextView) view.findViewById(R.id.textViewSingleRowRecordsDetailedViewCategoryFieldValue);
if(al_field_value.get(i).equals(""))
{
null_count = null_count + 1;
continue;
}
else
{
tv_field_name.setText(get_field_name(al_cat_field_id.get(i)));
tv_field_value.setText(al_field_value.get(i));
}
linearLayout_details.addView(view);
...

Try making your Textview multiline.
add below lines to your code to make textview multiline.
yourtextview.setSingleLine(false);
hope this helps

set the following to your tablelayout:-
tablename.setColumnShrinkable(ColumnIndex, true);

you can set the shrinkable attribute of the tablelayout to get the effect you want. the document from Android developer website :
The width of a column is defined by the row with the widest cell in
that column. However, a TableLayout can specify certain columns as
shrinkable or stretchable by calling setColumnShrinkable() or
setColumnStretchable(). If marked as shrinkable, the column width can
be shrunk to fit the table into its parent object. If marked as
stretchable, it can expand in width to fit any extra space. The total
width of the table is defined by its parent container. It is important
to remember that a column can be both shrinkable and stretchable. In
such a situation, the column will change its size to always use up the
available space, but never more. Finally, you can hide a column by
calling setColumnCollapsed().
example :
<TableLayout
android:id="#+id/fragment_print_job_detail_info_group"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:shrinkColumns="1"
android:layout_margin="#dimen/image_button_margin"
android:background="#drawable/round_corner_white_background_shape" >

TableLayout not centering

Here is my xml:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/test"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center" >
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
>
<TextView
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<TextView
android:id="#+id/editText2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
</TableRow>
I generate the rest dynamically.
Right now it centers it horizontally on the screen but everything is on the left side. I know its a simple fix but I can't seem to get it right.
Here is my manual code:
for(Item l : leaders)
{
// Make a new row
TableRow row = new TableRow(this);
row.setBackgroundColor(Color.DKGRAY);
TextView name= new TextView(this);
TextView score = new TextView(this);
createView(row, name, l.getName());
createView(row, score, String.valueOf(l.getScore()));
name.setTextColor(Color.MAGENTA); // Just to distinguish between the columns
// Add row to table layout
tl.addView(row);
}
}
private void createView(TableRow row, TextView textView, String string)
{
textView.setText(string);
textView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
textView.setTextColor(Color.CYAN);
textView.setTextSize(32);
textView.setPadding(20, 0, 0, 0);
row.setPadding(0, 1, 0, 1);
row.addView(textView);
}
Also, the given answers didn't change the layout.

If anybody has the same problem, the trick is to set
android:stretchColumns="0"
in the TableLayout and
android:layout_gravity="center"
android:layout_width="match_parent"
within the content views inside the rows.

I think u should write android:layout_gravity="center" in table layout instead of android:gravity="center".

and you can ad the layoutGravity Centre for Table Layout set in center in parrent Layouts
as
android:layout_gravity="center"
you can set the Gravity Centre
myTableLayout.setGravity(Gravity.CENTER);

Programmatic Layout with SetPadding and SetGravity

I am trying to duplicate the following layout programmatically; however, the setGravity and setPadding don't seem to have an effect:
I'm trying to recreate the textviews within the TableRows (note that there's padding and the second text view is right aligned). Also, I'm trying to recreate additional entries because they are dynamic:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/myinfo_root"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:scrollbars="vertical"
>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainTable"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1">
<TableRow>
<TextView
android:layout_column="1"
android:text="Text1"
android:padding="3dip" />
<TextView
android:id="#+id/text1"
android:text="TBD"
android:gravity="right"
android:padding="3dip" />
</TableRow>
<TableRow>
<TextView
android:layout_column="1"
android:text="Text2"
android:padding="3dip" />
<TextView
android:id="#+id/text2"
android:text="TBD"
android:gravity="right"
android:padding="3dip" />
</TableRow>
. . .
Here's a code snippet to add the TextViews. It seems to work but the entries don't have padding and are not right aligned.
int n = 0;
TableLayout table = (TableLayout) findViewById(R.id.mainTable);
for (int j=0; j<2; j++) {
Log.v(LOG_TAG, "entering for loop");
n++;
TableRow tr = new TableRow(getApplicationContext());
tr.setId(100+n);
String key = "hello";
float value = (float) 1.388);
value = value/3600;
TextView tvDynamicKey = new TextView(getApplicationContext());
TextView tvDynamicUnit = new TextView(getApplicationContext());
tvDynamicUnit.setText(Float.toString(value));
tvDynamicUnit.setGravity(Gravity.RIGHT);
tvDynamicKey.setText(key + " " + n);
tvDynamicKey.setPadding(3, 3, 3, 3);
tvDynamicUnit.setPadding(3, 3, 3, 3);
tr.addView(tvDynamicKey);
tr.addView(tvDynamicUnit);
table.addView(tr);
}
}

In your layout you always specify column1 for the left element (android:layout_column="1"). But you don't do it programmatically for the dynamic creation. You can do it like this. I tested it, it works on my environment.
tvDynamicKey.setLayoutParams(new TableRow.LayoutParams(1));
