App crashing when click to update edit text field (crashing from TextWatcher?)

Question

My app is crashing when the user clicks on an edit text field to update the entry. However, it doesn't crash when the field is blank and is being filled out the first time.

I believe I've narrowed down this down to the faulty code (in textwatcher code below) - however I can't see what I'm doing wrong. I'm further confused after looking at the stack trace - which appears to point to a missing drawable - but I can't see how these two are related. The stack trace is below as well.

Any help here would be appreciated! Please if you can give code examples on what I should try rather than just concepts it would help. Thanks in advance

Code in savesession.java

add_name.addTextChangedListener(new TextWatcher() {

   @Override
    public void onTextChanged(CharSequence s, int start, int before,
        int count) {
    }
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void afterTextChanged(Editable s) {
        Is_Valid_Person_Name(add_name);
    }
});

/* Copied in in response to comments for this code */

 public void Is_Valid_Person_Name(EditText edt) throws NumberFormatException 
 {
    if (edt.getText().toString().length() <= 0) 
    {
        edt.setError("Accept Alphabets Only.");
        valid_name = null;
    } else if (!edt.getText().toString().matches("[a-zA-Z ]+")) 
    {
      edt.setError("Accept Alphabets Only.");
      valid_name = null;
    } else {
      valid_name = edt.getText().toString();
    }
}

This issue was fixed by removing the customization to the theme. I believe the culprit was the customization to popupWindowStyle.

When editing existing text in a edittext box - a popup appears to show you where in the text field you are updating. If custom style mess up the appearance of this popup then you get the app crashes that I was getting.

<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
    <!-- Customize your theme here.
    <item name="android:itemTextAppearance">@style/your_new_text_appearance</item>
    <item name="android:popupBackground">@style/your_new_text_appearance</item>
    <item name="android:popupMenuStyle">@style/your_new_text_appearance</item>
    <item name="android:popupWindowStyle">@style/your_new_text_appearance</item>
    -->
</style>

Hi update your Is_Valid_Person_Name method code with this code . It really helps you.

public void Is_Valid_Person_Name(EditText edt) throws NumberFormatException 
    {
    Drawable warning = (Drawable)getResources().getDrawable(R.drawable.ic_launcher);
    warning.setBounds(new Rect(0, 0, warning.getIntrinsicWidth(), warning.getIntrinsicHeight()));
       if (edt.getText().toString().length() <= 0) 
       {
           edt.setError("Accept Alphabets Only.",warning);
           valid_name = null;
       } 
       else if (!edt.getText().toString().matches("[a-zA-Z ]+")) 
       {
         edt.setError("Accept Alphabets Only.",warning);
         valid_name = null;
       } else {
         valid_name = edt.getText().toString();
       }
   }

change the drawable icon according to you.

Answer 3

Because add_name is an EditText. You should set String in EditText and what is the type of parameter in this method Is_Valid_Person_Name(param) is it EditText or String check that.

Answer 4

you can call like this : Is_Valid_Person_Name(s.toString()); for checking.
