How can I change the value of XML tags through code (Java)?

Question

Android

Let's say we have a button, by clicking on it we moved the TextView by 25dp, how to do this?

android:layout_marginTop="10dp" как можно менять значение тегов?

Answer 1

TextView tvTemp = (TextView) findViewById(R.id. you_text_view );
LinearLayout.LayoutParams params = ( LinearLayout.LayoutParams ) tvTemp.getLayoutParams();
params.setMargins(0,25,0,0);
tvTemp.setLayoutParams(params);
LinearLayout.LayoutParams - depends on the current layout
