Android setText添加数字

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

更改为此name.setText(" Text " + number1 + " + " + number2);

两个数字的总和：name.setText(" Text " + number1 + " + " + number2 + " Sum :" + (number1+number2));

Answer 2

如果你想把它显示为你必须写的文字

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

如果你想总结2个数字，你必须写

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