我已經做其中CheckBox檢查不同的動作有Button依賴，這裏是代碼：做的東西，如果複選框被選中
public class CostiDiImpianto extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_costi_di_impianto);
}
public void onClick(View view) {
double Onorario1,SpeseD1,CostI1,Iva1,Deb1,Rit1,ccp1,Netto1;
//
Onorario1 = 0;
SpeseD1 = 0;
ccp1 = 0;
//
EditText Onorario = (EditText) findViewById(R.id.Onorario);
EditText SpeseD = (EditText) findViewById(R.id.SpeseD);
TextView CostI = (TextView) findViewById(R.id.CostI);
TextView Iva = (TextView) findViewById(R.id.Iva);
TextView Deb = (TextView) findViewById(R.id.Deb);
TextView Rit = (TextView) findViewById(R.id.Rit);
TextView ccp = (TextView) findViewById(R.id.ccp);
TextView Netto = (TextView) findViewById(R.id.Netto);
final CheckBox checkBox1=(CheckBox)findViewById(R.id.checkBox1);
final CheckBox checkBox2=(CheckBox)findViewById(R.id.checkBox2);
//
try{
Onorario1 = Math.round(Double.parseDouble(Onorario.getText().toString())*100.0)/100.0;
SpeseD1 = Math.round(Double.parseDouble(SpeseD.getText().toString())*100.0)/100.0;
} catch (NumberFormatException e){
ErrorMsg();
Pulisci(view);
return;
}
if(checkBox1.isChecked())
ccp1 = Onorario1 * 2/100;
Iva1 = (Onorario1 + ccp1)*22/100;
Rit1 = (Onorario1+ccp1+Iva1+SpeseD1)*20/100;
CostI1 = (Onorario1+ccp1+SpeseD1);
Deb1 = (Onorario1+ccp1+Iva1+SpeseD1);
Netto1 = (Onorario1+ccp1+Iva1+SpeseD1) - Rit1;
//
ccp.setText(Double.toString(round(ccp1,2)));
Iva.setText(Double.toString(round(Iva1,2)));
Rit.setText(Double.toString(round(Rit1,2)));
CostI.setText(Double.toString(round(CostI1,2)));
Deb.setText(Double.toString(round(Deb1,2)));
Netto.setText(Double.toString(round(Netto1,2)));
if(checkBox2.isChecked())
ccp1 = Onorario1 * 4/100;
Iva1 = (Onorario1 + ccp1)*22/100;
Rit1 = (Onorario1+ccp1+Iva1+SpeseD1)*20/100;
CostI1 = (Onorario1+ccp1+SpeseD1);
Deb1 = (Onorario1+ccp1+Iva1+SpeseD1);
Netto1 = (Onorario1+ccp1+Iva1+SpeseD1) - Rit1;
//
ccp.setText(Double.toString(round(ccp1,2)));
Iva.setText(Double.toString(round(Iva1,2)));
Rit.setText(Double.toString(round(Rit1,2)));
CostI.setText(Double.toString(round(CostI1,2)));
Deb.setText(Double.toString(round(Deb1,2)));
Netto.setText(Double.toString(round(Netto1,2)));
}
private void Pulisci(View view) {
EditText Onorario = (EditText) findViewById(R.id.Onorario);
EditText SpeseD = (EditText) findViewById(R.id.SpeseD);
TextView CostI = (TextView) findViewById(R.id.CostI);
TextView Iva = (TextView) findViewById(R.id.Iva);
TextView Deb = (TextView) findViewById(R.id.Deb);
TextView Rit = (TextView) findViewById(R.id.Rit);
TextView ccp = (TextView) findViewById(R.id.ccp);
TextView Netto = (TextView) findViewById(R.id.Netto);
Onorario.setText("");
SpeseD.setText("");
CostI.setText("");
Iva.setText("");
Deb.setText("");
Rit.setText("");
ccp.setText("");
Netto.setText("");
}
private void ErrorMsg() {
AlertDialog Msg = new AlertDialog.Builder(this).create();
Msg.setTitle("Errore");
Msg.setMessage("Hai inserito dei dati non validi!");
Msg.setButton(DialogInterface.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}});
Msg.show();
}
public static double round(double value, int places) {
if (places < 0) throw new IllegalArgumentException();
long factor = (long) Math.pow(10, places);
value = value * factor;
long tmp = Math.round(value);
return (double) tmp/factor;
}
}
但是，當我點擊clickbox程序中止。
我在做什麼錯？

請提供一個堆棧跟蹤。順便說一句，你應該添加一個偵聽器到你的複選框，如果你想根據事件做出動作 – nikis
你也可以使用radiogroup .. @ user3293120 – PSK
