自定义RadioButton_自定义组合的radiobutton

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);
    }
   
	@Override
	public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
		// TODO Auto-generated method stub
		switch(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;
		}
	}
}
