自定义RadioButton

来源：互联网发布：php 字符型转变为数值编辑：程序博客网时间：2024/05/29 07:08

Android提供的RadioButton样式和功能十分有限，在使用多个RadioButton进行单选的时候，RadioGroup并不好用，比如说它只能横着或者竖着排，却不能用其他排列方式。在这里自己没事瞎写一个自定义的RadioButton，实现效果如下：

源码如下:RadioButtonActivity.java

import android.app.Activity;import android.os.Bundle;import android.widget.CompoundButton;import android.widget.RadioButton;import android.widget.CompoundButton.OnCheckedChangeListener;public class RadioButtonActivity extends Activity implements OnCheckedChangeListener{RadioButton rb1;RadioButton rb2;RadioButton rb3;RadioButton rb4;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        rb1 = (RadioButton)findViewById(R.id.radioButton1);        rb2 = (RadioButton)findViewById(R.id.radioButton2);        rb3 = (RadioButton)findViewById(R.id.radioButton3);        rb4 = (RadioButton)findViewById(R.id.radioButton4);                rb1.setOnCheckedChangeListener(this);        rb2.setOnCheckedChangeListener(this);        rb3.setOnCheckedChangeListener(this);        rb4.setOnCheckedChangeListener(this);    }   @Overridepublic void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {// TODO Auto-generated method stubswitch(buttonView.getId()){case R.id.radioButton1:if(isChecked == true){rb1.setChecked(isChecked);rb2.setChecked(!isChecked);rb3.setChecked(!isChecked);rb4.setChecked(!isChecked);isChecked = false;}break;case R.id.radioButton2:if(isChecked == true){rb1.setChecked(!isChecked);rb2.setChecked(isChecked);rb3.setChecked(!isChecked);rb4.setChecked(!isChecked);isChecked = false;}break;case R.id.radioButton3:if(isChecked == true){rb1.setChecked(!isChecked);rb2.setChecked(!isChecked);rb3.setChecked(isChecked);rb4.setChecked(!isChecked);isChecked = false;}break;case R.id.radioButton4:if(isChecked == true){rb1.setChecked(!isChecked);rb2.setChecked(!isChecked);rb3.setChecked(!isChecked);rb4.setChecked(isChecked);isChecked = false;}break;default:break;}}}
