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++;
}
}

Is it possible to use TableRow like this:
That is array of TableRows. This must be inside table layout where table layout is nested inside linear layout.
TableRow[] tr = new TableRow[dimension];
Yes... this is abosutely possible in Android . TableRow is a class and you are trying to make an array of objects of a class .
Yes Absolutely Possible. check this link & try this code.
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);
}}

I'm trying to adding TableRows to a TableLayout, which is working fantastically. However, I'm running into some problems with layout parameters. The spacing between the TextViews within a TableRow isn't working out like I thought it would.
My current code looks as follows.
paymentTable = (TableLayout) findViewById(R.id.paymentTable);
for(i = 0; i < cursor.getCount(); i++) {
TableRow row = new TableRow(this);
TextView payAmount = new TextView(this);
payAmount.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_AMOUNT)));
payAmount.setPadding(payAmount.getPaddingLeft(),
payAmount.getPaddingTop(),
textView.getPaddingRight(),
payAmount.getPaddingBottom());
TextView payDate = new TextView(this);
payDate.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_DATE)));
row.addView(payDate);
row.addView(payAmount);
paymentTable.addView(row, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
cursor.moveToNext();
}
Afterwards, the TableLayout looks something along the lines of:
January$500
February$500
March$405
But I want it to look like:
January $500
February $500
March $405
To clarify things, I want each new TableRow and the TextViews it contains to inherit layout properties of an existing TableRow and TextView(s).
yawus this is a good tutorial will help you set the table layout
http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/
this is the xml layout
http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/6/
this is the activity code
http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/8/
TableRow tableRow= new TableRow(this);
ArrayList<Object> row = data.get(position);
TextView idText = new TextView(this);
idText.setText(row.get(0).toString());
tableRow.addView(idText);
TextView textOne = new TextView(this);
textOne.setText(row.get(1).toString());
tableRow.addView(textOne);
TextView textTwo = new TextView(this);
textTwo.setText(row.get(2).toString());
tableRow.addView(textTwo);
dataTable.addView(tableRow);
You need to add a RelativeLayout to each Table
TableRow row = new TableRow(this);
row.setId(tag);
// Creating a new RelativeLayout
RelativeLayout relativeLayout = new RelativeLayout(this);
// as the parent of that RelativeLayout is a TableRow you must use TableRow.LayoutParams
TableRow.LayoutParams rlp = new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.MATCH_PARENT);
rlp.setMargins(0, 0, 0, 0);
row.addView(relativeLayout, rlp);
Then you add your TextView to the RelativeLayout. Like this
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
TextView payAmount = new TextView(this);
//lp.setMargins(left, top, right, bottom)
lp.setMargins(0, 0, 16, 0);
lp.addRule(RelativeLayout.ALIGN_LEFT);
payAmount.setLayoutParams(lp);
relativeLayout.addView(payAmount);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
TextView payDate = new TextView(this);
//lp.setMargins(left, top, right, bottom)
lp.setMargins(0, 0, 16, 0);
lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
payDate.setLayoutParams(lp);
relativeLayout.addView(payDate);
This is the way I handle positioning interface components within a table row.
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);
}
I am trying to create a table from a 2-D array of strings. However, I suck in creating views in code, so for some reason my image is never visible and my textviews won't break into multilines, instead they chop of the text.
Also, I put id on every textview in my code, when someone click the textview, I was hoping I could use that ID to identify whick row was clicked. Unfortunately that wasn't the case.
Are there any good ways to identify correct row?
Regards
for (int current=0; current<cityArr.length; current++) {
TableRow tr = new TableRow(this);
tr.setId(100+current);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView labelTV = new TextView(this);
labelTV.setId(current);
labelTV.setText(cityArr[current][0]);
labelTV.setTextColor(Color.BLACK);
labelTV.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(labelTV);
ImageView mapView = new ImageView(this);
mapView.setImageResource(R.drawable.list_icon_map);
mapView.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT, 5));
tr.addView(mapView);
tlcity.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
public class MainActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ScrollView sv = new ScrollView(this);
TableLayout ll=new TableLayout(this);
HorizontalScrollView hsv = new HorizontalScrollView(this);
for(int i=1;i<30;i++) {
TableRow tbrow=new TableRow(this);
for(int j=1;j<=20;j++) {
TextView tv1=new TextView(this);
String s1 = Integer.toString(i);
String s2 = Integer.toString(j);
String s3 = s1+s2;
int id = Integer.parseInt(s3);
tv1.setId(id);
tv1.setText("Dynamic TextView no: "+id);
tbrow.addView(tv1);
}
ll.addView(tbrow);
}
hsv.addView(ll);
sv.addView(hsv);
setContentView(sv);
}
}
Ha, turned out to work alright with the setID() function. as long as I put the OnClickListener on the right component...
When a button is clicked, the following method is run:
public void createTableRow(View v) {
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));
}
R.id.spreadsheet is an xml TableLayout. I can see from debugging that the method is being accessed, but nothing is drawn to the screen. What gives? Do I need to reset the Content View somehow?
As it turns out, Eclipse is not always right. Ctrl+Shift+M made the wrong import. It had import android.view.ViewGroup.LayoutParams when it should have import android.widget.TableRow.LayoutParams
Everything works fine now.
