Question

for (int i = 0; i < rows; i++) {
            TableRow row =new TableRow(this);
            View v = new ImageView(getBaseContext());
            TextView tv_main =new TextView(this);
            ImageView iv = new imageView(this);                              
            tv_main.setText("Test");                
            iv.setImageDrawable(v.getResources().getDrawable(R.drawable.home_icon));
            row.addView(iv);
            row.addView(tv_main);
            table_layout.addView(row);
    }

How to set height and width programmatically? I had tried

iv.getLayoutParams().height=80;
iv.getLayoutParams().width=100;

but image is not display.

Answer 1

You need to create a new LayoutParams object and set the height and width for it and then pass it to the iv.setLayoutParams() method.

TableRow.LayoutParams layoutParams = new TableRow.LayoutParams(100, 80); 
iv.setLayoutParams(layoutParams);
