I hope to explain well what I want to achieve:
I'm from java code, defining buttons, TextView etc. but I'm having problems defining its properties, specifically for example: to a button, give property of padding, margin etc. I would like to access that part from the java code.
To define the padding of a button programmatically, it is done using the method setPadding () , if you check the documentation, it indicates that the integer values that are defined as arguments are:
setPadding (left padding, top padding , right padding, bottom padding)
This is an example:
Button mybutton = new Button(getApplicationContext());
//mybutton.setPadding(left, top, right, bottom);
mybutton.setPadding(10,20,10,20);
To define a margin progamatically, it is done by defining a LayoutParams , in which you can define margin values similar to setPadding() , example:
Button mybutton = new Button(getApplicationContext());
LayoutParams params = new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT
);
//params.setMargins(left, top, right, bottom);
params.setMargins(10, 20, 10, 20);
mybutton.setLayoutParams(params);
