我的工作，它收集用户的选择（从复选框），并将其发送到一个新的活动（当按钮是pressed）的应用程序。在新的活动，新的数据将被收集（EDITTEXT）和接收数据+新收集的数据将被合并，并通过电子邮件发送。

当我preSS 1号按钮，将复选框数据发送到新的活动，我得到一个错误

应用程序意外终止

下面是code：

 公共无效的onClick（视图v）
{

                   cakeDataformated（）;
                   //将数据（复选框）转换为字符串
                   串fianlformatedData = cakeDataformated（）;

                    意图I =新的意图（这一点，PersonData.class）;
                    i.putExtra（cakedata，fianlformatedData）;
                    startActivity（ⅰ）;

    }
 

和复选框转换方法是：

 公共字符串cakeDataformated（）{
    // TODO自动生成方法存根

    布尔checkyStatus1 = checky1.isChecked（）;
    布尔checkyStatus2 = checky2.isChecked（）;
    布尔checkyStatus3 = checky3.isChecked（）;
    布尔checkyStatus4 = checky4.isChecked（）;
            //读取复选框数据
    字符串形式= finalFormUsingFollowing（checkyStatus1，checkyStatus2，checkyStatus3，checkyStatus4）;
        //转换复选框响应到消息并保存为
            //一个名为字符串形式
            //例如：选择蛋糕：cake1，cake3
    返回的形式;


}
 

所以，如果有任何错误，请告诉我。

I am working on an application that gathers user selection (from a checkbox) and sends it to a new activity (when a button is pressed ). In the new activity, a new data will be collected (editText) and the received data + newly collected data will be combined and sent via email.

When I press the 1st button to send the checkbox data to the new activity, I get an error

The application has stopped unexpectedly

Here is the code:

 public void onClick(View v) 
{

                   cakeDataformated();
                   // to convert the data (checkBox) to a string
                   String fianlformatedData = cakeDataformated();

                    Intent i = new Intent(this, PersonData.class);  
                    i.putExtra("cakedata", fianlformatedData);
                    startActivity(i);

    }

and the check box conversion method is:

 public String cakeDataformated () {
    // TODO Auto-generated method stub

    boolean checkyStatus1 = checky1.isChecked();
    boolean checkyStatus2 = checky2.isChecked();
    boolean checkyStatus3 = checky3.isChecked();
    boolean checkyStatus4 = checky4.isChecked();
            // to read the checkbox data
    String form = finalFormUsingFollowing (checkyStatus1 ,checkyStatus2 ,checkyStatus3 , checkyStatus4 );
        //  to convert the check box response into a message and save it as 
            //  a string called form
            // example : cakes selected are : cake1 , cake3 
    return form ;


}

So, if there are any errors please tell me.

RadioGroup radioGroup = (RadioGroup) this
            .findViewById(R.id.radio_group);
    radioGroup
            .setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

                @Override
                public void onCheckedChanged(RadioGroup radioGroup, int id) {
                    final RadioButton radioButton = (RadioButton) radioGroup
                            .findViewById(id);

                    String selectedText = radioButton.getText().toString();
                    Intent i = new Intent(this, PersonData.class);
                    i.putExtra("cakedata", selectedText);
                    startActivity(i);
                }

            });
