android - Android setText 加号

Question

我需要做这样的事情：

name.setText("Text" + number1 "+" + number2);

为什么它在Android中不起作用？

Answer 1

改成这个name.setText(" Text " + number1 + " + " + number2);

两个数之和：name.setText(" Text " + number1 + " + " + number2 + " Sum :" + (number1+number2));

Answer 2

如果要将其显示为文本，则必须编写

name.setText("Text " + number1 + "+" + number2);

如果你想总结这两个数字，你必须写

name.setText("Text " + (number1+number2));
