回答1:

TextView tv;
----------------------
tv=new TextView(this);   // or  tv=new TextView(R.id.textview1);

LinearLayout.LayoutParams Params1 = new LinearLayout.LayoutParams(15,50);
tv.setLayoutParams(Params1);

I call new TableRow(), because textView's parent is TableRow. If your parent's view is LinearLayout, replace it by new LinearLayout.LayoutParams.

textView.setLayoutParams(
    new TableRow.LayoutParams(
        LayoutParams.WRAP_CONTENT, 
        LayoutParams.MATCH_PARENT));

I have experienced something similar in situations where there is a ScrollView in the parents hierarchy. No matter how I would modify layout inside it, my commands were ignored. If this is the case, try calling RequestLayout on the ScrollView or remove and re-add the child view of the ScrollView.
