RadioGroup中支持RadioButton多行多列

主要就是重写RadioGroup类：

package zq.com.radiogroupactivity;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;

/**

public class MyRadioGroup extends RadioGroup {
    private OnCheckedChangeListener mOnCheckedChangeListener;

    public MyRadioGroup(Context context) {
        super(context);
    }

    public MyRadioGroup(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public void setOnCheckedChangeListener(OnCheckedChangeListener listener) {
        mOnCheckedChangeListener = listener;
    }

    @Override
    public void addView(View child, int index, ViewGroup.LayoutParams params) {
        if (child instanceof LinearLayout) {
            int childCount = ((LinearLayout) child).getChildCount();
            for (int i = 0; i < childCount; i++) {
                View view = ((LinearLayout) child).getChildAt(i);
                if (view instanceof RadioButton) {
                    final RadioButton button = (RadioButton) view;
                    ((RadioButton) button).setOnTouchListener(new OnTouchListener() {

                        @Override
                        public boolean onTouch(View v, MotionEvent event) {
                            ((RadioButton) button).setChecked(true);
                            checkRadioButton((RadioButton) button);
                            if (mOnCheckedChangeListener != null) {
                                mOnCheckedChangeListener.onCheckedChanged(MyRadioGroup.this, button.getId());
                            }
                            return true;
                        }
                    });
                }
            }
        }
        super.addView(child, index, params);

    }

    private void checkRadioButton(RadioButton radioButton) {
        View child;
        int radioCount = getChildCount();
        for (int i = 0; i < radioCount; i++) {
            child = getChildAt(i);
            if (child instanceof RadioButton) {
                if (child == radioButton) {
                    // do nothing
                } else {
                    ((RadioButton) child).setChecked(false);
                }
            } else if (child instanceof LinearLayout) {
                int childCount = ((LinearLayout) child).getChildCount();
                for (int j = 0; j < childCount; j++) {
                    View view = ((LinearLayout) child).getChildAt(j);
                    if (view instanceof RadioButton) {
                        final RadioButton button = (RadioButton) view;
                        if (button == radioButton) {
                            // do nothing
                        } else {
                            ((RadioButton) button).setChecked(false);
                        }
                    }
                }
            }
        }
    }
}
然后就是activity_main.xml 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:text="Hello World!"/>

    <FrameLayout
        android:id="@+id/fragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"></FrameLayout>

</LinearLayout>
主类：Mactivity.class 

package zq.com.radiogroupactivity;

import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RadioFragment radioFragment = new RadioFragment();
        FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction transaction = fragmentManager.beginTransaction();
        transaction.replace(R.id.fragment,radioFragment);
        transaction.commit();

//        RadioGroup mRadio = findViewById(R.id.radiogroup);
//        mRadio.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
//            @Override
//            public void onCheckedChanged(RadioGroup radioGroup, int i) {
//                Log.e(TAG,"选择：" + i);
//                Toast.makeText(MainActivity.this, "你点击的是按钮" + i, Toast.LENGTH_SHORT).show();
//
//            }
//        });
    }
}
