Question

I am showing data of a <string name="whatsnew"> </string> in a textview and i have to show this textview only when the text inside this being changed.

for eg:

If previous state is:

<string name="whatsnew">Hi Stackoverflow Collegues </string>

If current state is this data is being updated as:

<string name="whatsnew">Hello Stackoverflow Collegues</string>

I have implemented a logic that i will retrieve the previous and current stringlength of

<string name="whatsnew"> </string>

containing text.But this logic has a loop hole if the updated text is of same length of previous string length.

Please help me with a better and efficient logic.

use hashCode() of your string to compare, for example:

int hash = "this is my string".hashCode();

or simply compare with another string:

boolean isSame = "first string".equalsIgnoreCase("second string");
