Question

I’ve been doing some experiments with “replaceall” function to change content of a file. But Im wondering if it possible to replace a string with text taken from text box.

Example:

File:

NAME: JOHN DOE
GRADES:BLAH BLAH BLAH BLAH

NAME: JOHN DOE
GRADES2: BLAH BLAH BLAH

NAME: JOHN DOE
GRADES3:BLAH BLAH BLAH

Then I would like to type in a textbox another “NAME” to replaceALL “JOHN DOE’s” with for example: “HULK HOGAN”

EXPECTED RESULT:

File:

NAME: HULK HOGAN
GRADES:BLAH BLAH BLAH BLAH

NAME: HULK HOGAN
GRADES2: BLAH BLAH BLAH

NAME: HULK HOGAN
GRADES3:BLAH BLAH BLAH

Is this possible???

Thanks in advance.

Answer 1

Yes.

Eg (assuming you have a TextView with id textView)

TextView t = (TextView) findViewById (R.id.textView);
String text = t.getText().toString();
String replaced = text.replaceAll (/*your implementation*/);
t.setText (replaced);

Same approach for EditTexts
