I tried to implement the Textwatcher interface, I am trying to change the text in `afterTextChanged()`, but it crashes. Why does this crash? : ``` @Override public void afterTextChanged(Editable s) { Editable myText; if(s.toString().contains("hi")){ myText = s.append(" ho"); myEdit.setText(myText); } } ``` Logcat ``` 01-27 01:23:18.213: E/AndroidRuntime(2563): FATAL EXCEPTION: main 01-27 01:23:18.213: E/AndroidRuntime(2563): java.lang.StackOverflowError 01-27 01:23:18.213: E/AndroidRuntime(2563): at android.graphics.Paint.getTextRunAdvances(Paint.java:1720) 01-27 01:23:18.213: E/AndroidRuntime(2563): at android.text.MeasuredText.addStyleRun(MeasuredText.java:164) 01-27 01:23:18.213: E/AndroidRuntime(2563): at android.text.MeasuredText.addStyleRun(MeasuredText.java:204) 01-27 01:23:18.213: E/AndroidRuntime(2563): at android.text.StaticLayout.generate(StaticLayout.java:281) 01-27 01:23:18.213: E/AndroidRuntime(2563): at android.text.DynamicLayout.reflow(DynamicLayout.java:284) 01-27 01:…

afterTextChanged crashes

android, textwatcher

Solution

You should call removeTextChangedListener() on your `EditText` before you set its text, and add your listener back after changing the text. Otherwise `afterTextChanged()` will keep getting called, like you've noticed.

I tried to implement the Textwatcher ``` @Override public void afterTextChanged(Editable Editable myText; if(s.toString().contains("hi")) myText = s.append(" ho"); myEdit.setText(myText); } } ``` Logcat ``` 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): 01-27 01:23:18.213: E/AndroidRuntime(2563): ``` interface, I am trying to change the text in `afterTextChanged()`, but it crashes.
