Width column tablelayout dynamically

Question

I have a problem regarding not using XML in the TableLayout. Someone has already asked the same as I do but the answer provided has been unable to help me. how to set width of column dynamically in android tablelayout?

Right now I have this

TableLayout tl = (TableLayout) findViewById(R.id.TableLayout1);
    /* Create a new row to be added. */
    TableRow tr = new TableRow(this);
    tr.setLayoutParams(new TableRow.LayoutParams(
            TableRow.LayoutParams.FILL_PARENT,
            TableRow.LayoutParams.WRAP_CONTENT));

    /* Create a Button to be the row-content. */
    Button b = new Button(this);
    b.setText("Dynamic Button");
    b.setLayoutParams(new TableRow.LayoutParams(
            TableRow.LayoutParams.FILL_PARENT,
            TableRow.LayoutParams.WRAP_CONTENT));
    /* Add Button to row. */

    tr.addView(b);
    Button a = new Button(this);
    a.setText("Dynamic Button");
    a.setLayoutParams(new TableRow.LayoutParams(
            TableRow.LayoutParams.FILL_PARENT,
            TableRow.LayoutParams.WRAP_CONTENT));
    /* Add Button to row. */
    a.setGravity(2);

    tr.addView(a);

But I fail to see how changing

tr.setLayoutParams

Will do the job of making for example the first button column 70% and the other button the 30%

you need setLayoutParams to your widget like following code:

TableRow.LayoutParams tlp = new TableRow.LayoutParams(width,heigh);
b.setLayoutParams(tlp);

TableRow.LayoutParams tlp1 = new TableRow.LayoutParams(width/3,heigh/3);
a.setLayoutParams(tlp1);
