Question

private void buildEmailText() {
    if (box1.isChecked()) emailText += "\nCoca-Cola";
    if (box2.isChecked()) emailText += "\nFanta";
    if (box3.isChecked()) emailText += "\nInca Cola";

来自一项活动

  if (box5.isChecked()) emailText += "\nEl Boricua de Pollo";

来自其他活动

 if (box6.isChecked()) emailText += "\nBebida 1/2 litro";
 if (box7.isChecked()) emailText += "\nBebida 1 1/2 litro";

我需要在不同活动中选择的一个选项将包含在一个邮件中

作为我需要的样本将是邮件

El boricua original
Bebida 1/2 litro
fanta

Answer 1

如果您需要为结果启动活动，请执行以下操作：

Intent intent = new Intent(v.getContext(), whichDrink.class);
intent.putExtra("Bebida 1/2 litro","Bebida 1/2 litro");
intent.putExtra("Bebida 1 1/2 litro","Bebida 1 1/2 litro");
startActivityForResult (intent, 0);

然后在其中的饮料活动类：

String firstValue = getIntent().getStringExtra("Bebida 1/2 litro");
String secondValue = getIntent().getStringExtra("Bebida 1 1/2 litro");

至少你应该将这些关键字符串提取到常量

Answer 2

试试这个

Intent intent = new Intent(v.getContext(), whichDrink.class.class);
intent.putExtra("DATA1","Bebida 1/2 litro");
intent.putExtra("DATA2","Bebida 1 1/2 litro");
startActivity(intent);

以whichDrink.class方式接收数据

String DATA1 = getIntent().getStringExtra("DATA1");
String DATA2 = getIntent().getStringExtra("DATA2");

如何将数据从复选框传递到另一个活动
