    package com.example.messi.myapplication;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;

public class chooseActivity extends AppCompatActivity {
    private TextView messi;
    private ImageView picture;
    private RadioGroup radio1;
    private RadioButton cluo;
    private RadioButton meixi;
    private RadioButton neymar;
    private RadioGroup radio2;
    private RadioButton suya;
    private RadioButton gezi;
    private RadioButton xiaoluo;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_choose);
        messi = (TextView) findViewById(R.id.messi);
        picture = (ImageView) findViewById(R.id.picture);
        radio1 = (RadioGroup) findViewById(R.id.radio1);
        cluo = (RadioButton) findViewById(R.id.cluo);
        meixi = (RadioButton) findViewById(R.id.meixi);
        neymar = (RadioButton) findViewById(R.id.neymar);
        radio2 = (RadioGroup) findViewById(R.id.radio2);
        suya = (RadioButton) findViewById(R.id.suya);
        gezi = (RadioButton) findViewById(R.id.gezi);
        xiaoluo = (RadioButton) findViewById(R.id.xiaoluo);

        radio1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            public void onCheckedChanged(RadioGroup radioGroup, int wqm) {
                if (cluo.isChecked()) {
                    picture.setImageResource(R.drawable.cluo);
                    radio1.clearCheck();
                }
                if (meixi.isChecked()) {
                    picture.setImageResource(R.drawable.meixi);
                    radio1.clearCheck();
                }
                if (neymar.isChecked()) {

                    radio1.clearCheck();
                }
                if (suya.isChecked()) {
                    picture.setImageResource(R.drawable.suya);
                    radio2.clearCheck();
                }
                if (gezi.isChecked()) {
                    picture.setImageResource(R.drawable.gezi);
                    radio2.clearCheck();
                }
                if (xiaoluo.isChecked()) {
                    picture.setImageResource(R.drawable.xiaoluo);
                    radio2.clearCheck();
