ゲームに5つの選択肢があるラジオボタンアクティビティがあります。これはクイズゲームなので、ユーザーは1つのエラー、2つのエラー、ツリー、4つおよび5つのエラーが発生するまでプレイすることを選択できます。私の質問は....5つのアクティビティと5つのクラスを作成する方が良いので、ユーザーがそのラジオボタンをチェックしたときに各アクティビティの意図を呼び出すことができます。ユーザーは、1、2、3、4、または5つのエラーまでカウントすることを選択しましたか？最初のオプションの実行方法は知っていますが、2番目のオプションの実行方法がわかりません。ここに私の選択活動：
public class Izbor extends Activity implements OnClickListener, OnCheckedChangeListener{
MediaPlayer buttonBack;
RadioButton rbDeset,rbDvadeset,rbNeogranicenoTriGreske,rbNeogranicenoJednaGreska,rbNeogranicenoPetGresaka;
Button dNazad, dStart;
RadioGroup rGrupa;
TextView tv1;
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.izbor);
addListenerOnButton();
}
private void addListenerOnButton() {
Typeface dugmad = Typeface.createFromAsset(getAssets(), "Bebas.ttf");
Typeface pitanjeVrh = Typeface.createFromAsset(getAssets(), "Lobster.ttf");
rbDeset = (RadioButton) findViewById(R.id.radio1);
rbDvadeset = (RadioButton) findViewById(R.id.radio2);
rbNeogranicenoJednaGreska = (RadioButton) findViewById(R.id.radio3);
rbNeogranicenoTriGreske = (RadioButton) findViewById(R.id.radio4);
rbNeogranicenoPetGresaka = (RadioButton) findViewById(R.id.radio5);
dNazad = (Button) findViewById(R.id.bNazad);
dStart = (Button) findViewById(R.id.bStart);
rGrupa = (RadioGroup) findViewById(R.id.radioGroup1);
buttonBack = MediaPlayer.create(Izbor.this, R.raw.back);
tv1 = (TextView) findViewById(R.id.tv1);
dNazad.setTypeface(dugmad);
dStart.setTypeface(dugmad);
rbDeset.setTypeface(dugmad);
rbDvadeset.setTypeface(dugmad);
rbNeogranicenoPetGresaka.setTypeface(dugmad);
rbNeogranicenoJednaGreska.setTypeface(dugmad);
rbNeogranicenoTriGreske.setTypeface(dugmad);
tv1.setTypeface(pitanjeVrh);
rGrupa.setOnCheckedChangeListener(this);
rbDeset.setOnClickListener(this);
rbDvadeset.setOnClickListener(this);
rbNeogranicenoJednaGreska.setOnClickListener(this);
rbNeogranicenoTriGreske.setOnClickListener(this);
rbNeogranicenoPetGresaka.setOnClickListener(this);
dStart.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(rbDeset.isChecked()){
startActivity(new Intent("rs.androidaplikacijekvizopstekulture.KVIZ"));
}else if(rbDvadeset.isChecked()){
startActivity(new Intent("rs.androidaplikacijekvizopstekulture.DVADESETPITANJA"));
}else if(rbNeogranicenoJednaGreska.isChecked()){
startActivity(new Intent("rs.androidaplikacijekvizopstekulture.TRIDESETPITANJA"));
}else if(rbNeogranicenoPetGresaka.isChecked()){
startActivity(new Intent("rs.androidaplikacijekvizopstekulture.NEOGRANICENOPETGRESAKA"));
}
}
});
dNazad.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
buttonBack.start();
finish();
}
});
}
public void onCheckedChanged(RadioGroup group, int checkedId) {
}
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
そして、これがユーザーが5つのミスまでプレイできる1つのアクティビティです。
