如何减少if-else语句 [英] How can I reduce if-else statements

问题描述

我的代码：

if(!"".equals(et1.getText().toString())){
   Toast.makeText(getActivity(), "Please enter text1", Toast.LENGTH_SHORT).show();
} else if(!"".equals(et2.getText().toString())){
   Toast.makeText(getActivity(), "Please enter text2", Toast.LENGTH_SHORT).show();
} else if(!"".equals(et3.getText().toString())){
   Toast.makeText(getActivity(), "Please enter text3", Toast.LENGTH_SHORT).show();
} else if(!"".equals(et4.getText().toString())){
   Toast.makeText(getActivity(), "Please enter text4", Toast.LENGTH_SHORT).show();
} else if(!"".equals(et5.getText().toString())){
   Toast.makeText(getActivity(), "Please enter text5", Toast.LENGTH_SHORT).show();
} 

//共有13个字段，所以这将接近13个检查。所以我想知道是否有可能检查一个陈述并找出哪个陈述是空的。

//Totally 13 fields, so this will go near 13 checking. So just I want to know is there any possibility to check with one statement and find which filed is leaved as empty.

谢谢。

推荐答案

将其存储在列表中

for (EditText et : etList) {
    if(!"".equals(et.getText().toString()))
}
