Android的替换字符串 [英] Android Replace Strings

问题描述

你如何替换字符串时，您检索的活动数据？我不能似乎找到谷歌。也许我的问题太简单了。请参阅下面的codeS。

 意图= getIntent（）;
textToPass = in.getStringExtra（textToPass）;
 

textToPass实际上是一个字符串，如。 ExampleText.txt

你如何删除.TXT，使它看起来像ExampleText

我可能是附近的某个地方，但我还是想不出弄清楚

 字符串exampletext = textToPass.getText（）的toString（）代替（TXT）。;
 

解决方案

下面textToPass是字符串，这样你就可以直接申请替代方法就可以了。

  textToPass.replace（TXT）;
 

How do you replace strings when you retrieve a data from an activity ? I cant seems to find it google. Maybe my question is too simple. Please see the below codes.

Intent in = getIntent();
textToPass = in.getStringExtra("textToPass");

textToPass is actually a string eg. "ExampleText.txt"

How do you remove the .txt to make it look like "ExampleText"

I might be somewhere near, but I still couldnt figure out

String exampletext = textToPass.getText().toString().replace(".txt","");

解决方案

Here textToPass is string so you can directly apply replace method on it .

textToPass.replace(".txt","");
