带有图像的单选按钮

Question

如何使用图片制作RadioButton，问题如下。当我们回答问题时，图片也会在RadioButton中发生变化。因为当我已回答问题时，他们仍然使用相同的图像。

我的意思是，当我们已经回答了问题时，RadioButton处的图像也会随着问题的变化而改变。我将图像放在RadioButton xml，如何将图像放在RadioButton类

是否有可能或者我必须全部改变？

String Question[]={"HAHA","HAHA2","HAHA3"};

String ans[]={"i1","12","i3"};

String opt[]={"i1","lali","uu","12","hehe","oo","i3","jj","cc"};

in opt[]我们放置图片还是必须全部更改？所以我想把图像放在字符串

    public class FamilyQuestion extends ActionBarActivity {

    TextView tv;
    Button btnNext;
    RadioGroup rg;
    RadioButton bt1,bt2,bt3;
    String Question[]={"HAHA","HAHA2","HAHA3"};
    String ans[]={"i1","12","i3"};
    String opt[]={"i1","lali","uu","12","hehe","oo","i3","jj","cc"};

    int flag=0;
    public static int mark,correct,wrong;

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

        tv=(TextView) findViewById(R.id.tvque);
        btnNext=(Button) findViewById(R.id.btnNext);
        rg = (RadioGroup) findViewById(R.id.rg);
        bt1 = (RadioButton) findViewById(R.id.btn1);
        bt2 = (RadioButton) findViewById(R.id.btn2);
        bt3 = (RadioButton) findViewById(R.id.btn3);

        tv.setText(Question[flag]);
        bt1.setText(opt[0]);
        bt2.setText(opt[1]);
        bt3.setText(opt[2]);

        Toast.makeText(this, "Negative Mark : " + Test.tbflag, 1000).show();
        btnNext.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                RadioButton uans=(RadioButton)findViewById(rg.getCheckedRadioButtonId());
                String ansText= uans.getText().toString();

                if (ansText.equalsIgnoreCase(ans[flag]))
                {
                    correct++;
                    flag++;
                }
                else
                {
                    wrong++;

                }

                if(flag<Question.length)
                {
                    tv.setText(Question[flag]);
                    bt1.setText(opt[flag*3]);
                    bt2.setText(opt[(flag*3)+1]);
                    bt3.setText(opt[(flag*3)+2]);
                }
                else
                {
                    if(Test.tbflag)
                    {
                        mark=correct-wrong;
                    }
                    else
                    {
                        mark=correct;
                    }
                    Intent in=new Intent(getApplicationContext(),ResultActivity.class);
                    in.putExtra("question", "family");
                    startActivity(in);
                }
            }
        });

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_family_question, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
