I am trying to add a tableLayout at runtime to the existing LinearLayout in main.xml. I have added a editText(R.id.editText1) in the main.xml. Here's my code. Its not working. I ge

Solution 1:

Before your loop add :

Arraylist<TableRow> tr = new ArrayList<TableRow>;

In the loop instead of :

TableRowtr=newTableRow(this);

Put :

tr.add(new TableRow(this));

And finally replace your tr by tr.get(r). Something like these modifications should help you because, you erase your tr at each turn of your loop with your :

TableRowtr=newTableRow(this);

Solution 2:

Mr. Happy Go Lucky just do one thing write setContentView(R.layout.your Main Layout); beofre text = (EditText)findViewById(R.id.editText1); means at top of the onCreate() method because we cant define any view before setContentView.

without any setContentView you cant find any view like as findViewById(R.id.editText1);

Solution 3:

Below line will be the first one after super.onCreate(savedInstanceState);

setContentView(mainLayout);

then only findViewByid works
