关于获取RadioGroup里面的RadioButton的值，多行RadioGroup展示清除选中效果

代码部分：

public class MainActivity extends Activity {

public TextView mTextView1;
   public RadioGroup mRadioGroup1,mRadioGroup2;
   public RadioButton mRadio1, mRadio2,mRadio3,mRadio4;
   public Button submit;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        // 取得 TextView、RadioGroup、RadioButton对象

        mTextView1 = (TextView) findViewById(R.id.myTextView);

        submit = (Button) findViewById(R.id.submit);

        mRadioGroup1 = (RadioGroup) findViewById(R.id.myRadioGroup);

        mRadio1 = (RadioButton) findViewById(R.id.myRadioButton1);

        mRadio2 = (RadioButton) findViewById(R.id.myRadioButton2);

        mRadioGroup2 = (RadioGroup) findViewById(R.id.myRadioGroup2);

        mRadio3 = (RadioButton) findViewById(R.id.myRadioButton3);

        mRadio4 = (RadioButton) findViewById(R.id.myRadioButton4);

        submit.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
if(mTextView1.getText().toString().equals("")){
       
 Toast toast = Toast.makeText(MainActivity.this, "mTextView1为空"+mTextView1.getText().toString(), Toast.LENGTH_SHORT);                    
       
       toast.show();                
       
}else{
       
 Toast toast = Toast.makeText(MainActivity.this, "mTextView1选中的值为:"+mTextView1.getText().toString(), Toast.LENGTH_SHORT);                    
       
       toast.show(); 
       
}

}
});

       

        mRadioGroup1.setOnCheckedChangeListener(new OnMyManholeStateOneCheckedChangeListener());

        mRadioGroup2.setOnCheckedChangeListener(new OnMyManholeStateTwoCheckedChangeListener());

    }

    
private class OnMyManholeStateOneCheckedChangeListener implements
RadioGroup.OnCheckedChangeListener {

@Override
public void onCheckedChanged(RadioGroup radioGroup, int position) {

switch (position) {
case R.id.myRadioButton1:
if (mRadio1.isChecked())
mRadioGroup2.clearCheck();//清除RadioGroup2的选中状态
 mTextView1.setText(mRadio1.getText());

break;
case R.id.myRadioButton2:
if (mRadio2.isChecked())
mRadioGroup2.clearCheck();
mTextView1.setText(mRadio2.getText());

break;

default:
break;
}
}
}

private class OnMyManholeStateTwoCheckedChangeListener implements
RadioGroup.OnCheckedChangeListener {

@Override
public void onCheckedChanged(RadioGroup radioGroup, int position) {
switch (position) {
case R.id.myRadioButton3:
if (mRadio3.isChecked())
mRadioGroup1.clearCheck();//清除RadioGroup1的选中状态
mTextView1.setText(mRadio3.getText());

break;
case R.id.myRadioButton4:
if (mRadio4.isChecked())
mRadioGroup1.clearCheck();
mTextView1.setText(mRadio4.getText());
break;

default:
break;
}

}
}

 
}
