使一个按钮做一些事情，取决于哪个CheckBox被选中

我已经写了这段代码，请告诉我该怎么做才能使Button执行某些操作，具体取决于选中哪个CheckBox。使一个按钮做一些事情，取决于哪个CheckBox被选中

@Override

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_costi_di_impianto);

     }}); 
    Msg.show(); 
} 
public static double round(double value, int places) { 
    if (places < 0) throw new IllegalArgumentException(); 

    long factor = (long) Math.pow(10, places);

    return (double) tmp/factor; 
} 

}

这里是logcat的

使用oncheckedchangelistener ... \ – Ranjit

我应该在哪里放？ – user3293120

实现接口，然后重写方法来侦听复选框更改，然后在该方法内部执行任何想要的按钮。 – Eenvincible

您可以使用监听器，这样的：

checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
      if (isChecked){ 

      } else { 

      } 
     } 
});

设置setOnClickListener()您checkboxs。

checkBox1.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) {    
     if (((CheckBox) v).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)));  
     } 
     } 
    }); 

checkBox2.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) {    
     if (((CheckBox) v).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))); 
     } 
     } 
    });

或setOnCheckedChangeListener()。

checkBox1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
      if (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)));  
     } 
}); 

checkBox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
      if (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))); 
     } 
});

现在，当我按复选框它做calcs，并按钮导致异常 – user3293120

使用setOnCheckedChangeListener（），wath异常给我更多的细节？ – Jorgesys

使用setOnCheckedChangeListener（），它会给出该活动类com.ITE.economiaaziendale中的方法OnClickListener（View）无法找到方法OnLayListener（View） 02-11 19：17：45.071：E/AndroidRuntime（488）：java.lang.IllegalStateException： CostiDiImpianto for onClick处理程序在视图类android.widget.CheckBox ID为'checkBox2' – user3293120

首先全局定义的所有意见，并在你的活动类，即实现你的onCheckedChangedListener：

Edittext Onorario, SpeseD; 
TextView CostI, Iva, Deb, Rit, ccp, Netto; 
CheckBox checkBox1, checkBox2; 
public class YourActivity extends Activity implements onCheckedChangedListener {

然后做你的onCreate方法，即在初始化过程：

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

Onorario = (EditText) findViewById(R.id.Onorario); 
SpeseD = (EditText) findViewById(R.id.SpeseD); 
CostI = (TextView) findViewById(R.id.CostI); 
Iva = (TextView) findViewById(R.id.Iva); 
Deb = (TextView) findViewById(R.id.Deb); 
Rit = (TextView) findViewById(R.id.Rit); 
ccp = (TextView) findViewById(R.id.ccp); 
Netto = (TextView) findViewById(R.id.Netto); 
checkBox1=(CheckBox)findViewById(R.id.checkBox1); 
checkBox2=(CheckBox)findViewById(R.id.checkBox2); 
//Here add your onCheckedChangedListener to each checkbox 
checkBox1.setOnCheckedChangeListener(this); 
checkBox2.setOnCheckedChangeListener(this); 
}

现在在你的setOnCheckedChangeListener上做你喜欢的事情即

@Override 
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
// TODO Auto-generated method stub 

switch (buttonView.getId()){ 

case R.id.checkBox1: 
    if(isChecked){ 
    //Do here all your button click stuff or set text to any edittext or textview if the first ckeckbox is checked.. 

    }else{ 
    //do something if the checkbox1 is not checked 
    } 
    break; 
case R.id.checkBox2: 
    if(isChecked){ 
    //do here what you want to do when checkbox2 is checked 
    }else{ 
    //and here when the checkbox2 is not checked 
    } 
    break; 
}

这里所有的答案都是正确的，但你的问题在于写作标准。正如我在你的代码中看到的，你的onCreate方法知道所有东西。因此，以一种好的方式处理所有进程，这将有助于您找到编译错误和运行时错误。
