Gravity.

Also, If you want the message to display from bottom to top, you need to add them to the ViewGroup in that order.

Set the Gravity to BOTTOM

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT);
            params.weight = 1.0f;
            params.gravity=48;

            button.setLayoutParams(params);

For gravity values and how to set gravity check Gravity

You can add it programmatically with:

LinearLayout layout = findViewById(R.id.layout);
layout.addView(newView, index);

You just have to add always with index = 0

And you can also use android:gravity="bottom"
