Still could not get it working.
To simplify the debugging, I have written some test code (downloaded
it from a forum actually:)). I wonder why even this does not work.
public class TestTableLayout extends Activity {
int PROVINCE_Alberta = 0;
int PROVINCE_BC = 1;
int PROVINCE_Manitoba = 2;
int PROVINCE_NewBrunswick = 3;
int PROVINCE_Newfoundland = 4;
int PROVINCE_Northwest = 5;
int PROVINCE_NovaScotia = 6;
int PROVINCE_Nunavut = 7;
int PROVINCE_Ontario = 8;
int PROVINCE_PEI = 9;
int PROVINCE_Quebec = 10;
int PROVINCE_Saskatchewan = 11;
int PROVINCE_Yukon = 12;
int numProvinces = 13;
String[] provinces = new String[numProvinces];
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
provinces[PROVINCE_Alberta] = "Alberta";
provinces[PROVINCE_BC] = "British Columbia";
provinces[PROVINCE_Manitoba] = "Manitoba";
provinces[PROVINCE_NewBrunswick] = "New Brunswick";
provinces[PROVINCE_Newfoundland] = "Newfoundland and
Labrador";
provinces[PROVINCE_Northwest] = "Northwest Territories";
provinces[PROVINCE_NovaScotia] = "Nova Scotia";
provinces[PROVINCE_Nunavut] = "Nunavut";
provinces[PROVINCE_Ontario] = "Ontario";
provinces[PROVINCE_PEI] = "Prince Edward Island";
provinces[PROVINCE_Quebec] = "Quebec";
provinces[PROVINCE_Saskatchewan] = "Saskatchewan";
provinces[PROVINCE_Yukon] = "Yukon";
// Get the TableLayout
TableLayout tl = (TableLayout) findViewById(R.id.maintable);
// Go through each item in the array
for (int current = 0; current < numProvinces; current++)
{
// Create a TableRow and give it an ID
TableRow tr = new TableRow(this);
tr.setId(100+current);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
// Create a TextView to house the name of the province
TextView labelTV = new TextView(this);
labelTV.setId(200+current);
labelTV.setText(provinces[current]);
labelTV.setTextColor(Color.BLACK);
labelTV.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(labelTV);
// Create a TextView to house the value of the after-tax
income
TextView valueTV = new TextView(this);
valueTV.setId(current);
valueTV.setText("$0");
valueTV.setTextColor(Color.BLACK);
valueTV.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(valueTV);
// Add the TableRow to the TableLayout
tl.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
tl.invalidate();
}
}
