High-end RadioButton setting in Android code

I don't know how to start the title.

 

At present, I will focus on two aspects:

 

1. Code setting @ null

// Null is not allowed here. You must set radioButton as follows. setButtonDrawable (getResources (). getDrawable (android. r. color. transparent); // For background, you can simply use nullradioButton. setBackground (null );

 

 

2. Create a control object using a layout Template

First, create an xml Script Template for the layout of a single control that contains all default parameters. This is similar to the item layout script used to create a ListView.

<?xml version="1.0" encoding="utf-8"?><RadioButton xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="0dp"    android:layout_height="wrap_content"    android:layout_gravity="center"    android:layout_weight="1"    android:background="@null"    android:button="@null"    android:drawablePadding="-20dp"    android:drawableTop="@drawable/cat" />

 

Introduce the template above through code to create a new object

RadioButton radioButton = (RadioButton) getLayoutInflater().inflate(R.layout.radiobutton, null);
