Adding TableRows dynamically in Android doesn't work

I got a little problem with adding tablerows to a table layout in android.
Here's my code:
int z = 0;
for(String detail: details){
TableRow tr = new TableRow(this);
tr.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
//odd / even
if(z%2 == 0)
tr.setBackgroundColor(Color.parseColor("#F5F5F5"));
//set detail text
TextView detailText = new TextView(this);
RelativeLayout.LayoutParams dtlp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
detailText.setTextSize(16.0f);
detailText.setTextColor(Color.parseColor("#333333"));
detailText.setPadding(20, 10, 20, 10);
detailText.setLayoutParams(dtlp);
detailText.setText(detail);
tr.addView(detailText);
detailsTable.addView(tr);
++z;
}
I cannot figure out where the problem is. The detail textview is being set but the tablerows won't show up.

a. Try changing dtlp's "width parameter" to "RelativeLayout.MATCH_PARENT"
OR
b. Before For loop block create two layout params like this.
TableLayout.LayoutParams tlps=new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT);
TableRow.LayoutParams trps=new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT);
In loop Replace
detailText.setLayoutParams(dtlp);
WITH
detailText.setLayoutParams(trps);
And replace
detailsTable.addView(tr);
with
detailsTable.addView(tr,tlps);
hope this helps.

Android Adding more than one TextView to a TableRow Programmatically

I have a LinearLayout inside a FrameLayout for tab purposes. And I'm trying to add TableRow's to the LinearLayout in the code.
LinearLayout testLayout = (LinearLayout)findViewById(R.id.testLayout);
TableRow tableRow = new TableRow(this);
tableRow.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));
This gets my LinearLayout and creates a TableRow to the specifications I want. I know this part is working.
TextView textOne = new TextView(this);
textOne.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
textOne.setText("One");
TextView textTwo = new TextView(this);
textTwo.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
textTwo.setText("Two");
Here I make my two TextViews with no problem.
tableRow.addView(textOne);
tableRow.addView(textTwo);
testLayout.addView(tableRow, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
Here is where I assume everything goes wrong. What happens is it only shows the textTwo. I don't know why it's not showing both of them in order like a normal TableRow would in XML. And I repeat, this must be done in code.
Please help, thank you.

Have you imported this import android.widget.TableRow.LayoutParams
Below code works for me
TableLayout tl = (TableLayout) findViewById(R.id.spreadsheet);
TableRow tr = new TableRow(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
TextView tvLeft = new TextView(this);
tvLeft.setLayoutParams(lp);
tvLeft.setBackgroundColor(Color.WHITE);
tvLeft.setText("OMG");
TextView tvCenter = new TextView(this);
tvCenter.setLayoutParams(lp);
tvCenter.setBackgroundColor(Color.WHITE);
tvCenter.setText("It");
TextView tvRight = new TextView(this);
tvRight.setLayoutParams(lp);
tvRight.setBackgroundColor(Color.WHITE);
tvRight.setText("WORKED!!!");
tr.addView(tvLeft);
tr.addView(tvCenter);
tr.addView(tvRight);
tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
tl.addView(tr, new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));

I think you want to create your TextView dynamically and should're getting error "removeView () parent." Here is a good solution for that:
TableView tlSkills = (TableView) findViewById(R.id.myTableView);
if(listSkills.size() > 0) {
TableRow tableRow = new TableRow(getContext());
int i = 0;
for (Skills s : listSkills) {
TextView textView = new TextView(getContext());
textView.setText("" + s.getName());
tableRow.addView(textView);
if(i > 0) {
tlSkills.removeView(tableRow);//this is to avoid the error I mentioned above.
}
tlSkills.addView(tableRow);
i++;
}
}

View not showing in layout when layoutparams is set programatically

Every time I set the layout param of TextView to wrap content or fill parent it's not showing in the view, but when I set it to pixels it's working why is that?
Here is the relevant code:
items = (LinearLayout) findViewById(R.id.llmain);
tb = new TableLayout(MainActivity.this);
tb.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
tb.setGravity(Gravity.CENTER);
TableRow tr = new TableRow(MainActivity.this);
ImageButton ima = new ImageButton(MainActivity.this);
ImageButton imr = new ImageButton(MainActivity.this);
TextView tvin = new TextView(this);
TableRow.LayoutParams trp = new TableRow.LayoutParams();
trp.setMargins(0, 0, 0, 10);
tr.setLayoutParams(trp);
tr.setGravity(Gravity.CENTER);
ima.setBackgroundColor(Color.TRANSPARENT);
ima.setImageResource(R.drawable.add);
imr.setBackgroundColor(Color.TRANSPARENT);
imr.setImageResource(R.drawable.remove);
tvin.setWidth(100);
tvin.setHeight(45);
tvin.setGravity(Gravity.CENTER);
tvin.setText(sil[i]);
tvin.setBackgroundColor(Color.rgb(200, 0, 255));
tr.addView(ima);
tr.addView(tvin);
tr.addView(imr);
tb.addView(tr);
items.addView(tb);
I tried using this
tvin.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
and this
tvin.setWidth(LayoutParams.FILL_PARENT);
tvin.setHeight(LayoutParams.FILL_PARENT);
but none of these work.

Try:
tvin.setLayoutParams(new TableRow.LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
and remove the tvin.setWidth and height.
You should always set the layout params of view's parent, TableRow in this case.
MATCH_PARENT makes no difference but it's a new name and you should be using it instead of FILL_PARENT.

In this Line u have to use height and width .. TableRow.LayoutParams trp = new TableRow.LayoutParams(); Like this
TableRow row = new TableRow(context);
row.setLayoutParams(new android.widget.TableRow.LayoutParams(android.widget.TableRow.LayoutParams.FILL_PARENT,
android.widget.TableRow.LayoutParams.WRAP_CONTENT));

Try to use the LinearLayout.LayoutParams
TextView tvin = new TextView(this);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
tvin.setLayoutParams(llp);

Android: How to create such layout dynamicaly (not by xml)?

In My application i want to create the layout as like below image:
So How to make it possible ?
I have done Something like below code:
public void showResult()
{
List<TextView> textListWord = new ArrayList<TextView>(tempEmployerList.size());
List<TextView> textListAnswer = new ArrayList<TextView>(tempEmployerList.size());
List<TextView> imageListAnswer = new ArrayList<TextView>(tempEmployerList.size());
for(int i = 0; i<=tempEmployerList.size()-1; i++)
{
LinearLayout innerLayout = new LinearLayout(this);
innerLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
innerLayout.setBackgroundColor(0x00000000);
// set the Multiple TextView
TextView mHeading = new TextView(getApplicationContext());
TextView middleValue = new TextView(getApplicationContext());
TextView aImageView = new TextView(getApplicationContext());
mHeading.setText("\n"+"1");
//mHeading.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
mHeading.setTextColor(0xFFFF0000);
mHeading.setPadding(3, 0, 0, 0);
middleValue.setText("\n"+"2");
//middleValue.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
middleValue.setTextColor(0xFFFF0000);
middleValue.setGravity(Gravity.RIGHT);
middleValue.setPadding(2, 0, 9, 0);
aImageView.setText("\n"+"3");
//aImageView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
aImageView.setGravity(Gravity.RIGHT);
aImageView.setTextColor(0xFF000000);
aImageView.setPadding(0, 0, 9, 0);
View line = new View(getApplicationContext());
//line.setOrientation(1);
line.setLayoutParams(new LayoutParams(2, android.view.ViewGroup.LayoutParams.FILL_PARENT));
line.setBackgroundColor(0xFF000000);
/**** Any other text view setup code ****/
innerLayout.addView(mHeading);
innerLayout.addView(middleValue);
innerLayout.addView(aImageView);
innerLayout.addView(line);
myLinearLayout.addView(innerLayout);
textListWord.add(mHeading);
textListAnswer.add(middleValue);
imageListAnswer.add(aImageView);
}
}
So please guide me that what more i have to do to create such view ?
Thanks.

try TableLayout and TableRow instead of LinearLayout.
You can create TableLayout in xml as well, as it, I think would be static and add TableRows. To Create a TableLayout in Java use,
TableLayout tblLayout=new TableLayout(this);
Set LayoutParams and other properties of table layout in java, like I am setting LayoutParams:
LayoutParams params=new LayoutParams(LayoutParams.Fill_Parent, LayoutParams.Wrap_Content);
tblLayout.setLayoutParams(params);
Create a loop for TableRows creation and insertion:
for(int i=0;i<arrList1.size();i++)
{
TableRow row=new TableRow(this);
row.setLayoutParams(params);
TextView lbl1=new TextView(this);
lbl1.setText(arrList1.get(i));
row.addView(lbl1);
TextView lbl2=new TextView(this);
lbl2.setText(arrList2.get(i));
row.addView(lbl2);
TextView lbl3=new TextView(this);
lbl3.setText(arrList3.get(i));
row.addView(lbl3);
tblLayout.addView(row);
}

Android: Programmatically Setting width of Child View using Percentage

I've read this article:
Setting width of Child View using Percentage
So far it works great if we set the weight and width in XML but I want to do it programmatically. I've a table in my layout (XML) and I am adding rows to it programmatically. In each row, I am adding 2 Text Views. I tried doing like this:
TableLayout tl = (TableLayout)findViewById(R.id.myTable);
for(int i = 0; i < nl.getLength(); i++){
NamedNodeMap np = nl.item(i).getAttributes();
TableRow trDetails = new TableRow(this);
trDetails.setBackgroundColor(Color.BLACK);
TextView tvInfo = new TextView(this);
tvInfo.setTextColor(Color.WHITE);
tvInfo.setGravity(Gravity.LEFT);
tvInfo.setPadding(3, 3, 3, 3);
tvInfo.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 10);
tvInfo.setText("info");
TextView tvDetails = new TextView(this);
tvDetails.setTextColor(Color.WHITE);
tvDetails.setGravity(Gravity.LEFT);
tvDetails.setPadding(3, 3, 3, 3);
tvDetails.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 10);
tvDetails.setText(np.getNamedItem("d").getNodeValue());
trDetails.addView(tvInfo, new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 0.50f));
trDetails.addView(tvDetails, new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 0.50f));
tl.addView(trDetails,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
but with no luck, it shows blank screen but if I do it in XML then it shows perfectly. Please help me sorting out this issue where I am doing wrong?
Thanks

You should use TableRow.LayoutParams and not Linearlayout.LayoutParams
trDetails.addView(tvInfo, new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 0.50));
trDetails.addView(tvDetails, new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 0.50));
