Annotation Type TextChange

@Retention(value=CLASS)
 @Target(value=METHOD)
public @interface TextChange

This annotation is intended to be used on methods to receive events defined by TextWatcher.onTextChanged(CharSequence s, int start, int before, int count) when the text is changed on the targeted TextView or subclass of TextView.

The annotation value should be one or several R.id.* fields that refers to TextView or subclasses of TextView. If not set, the method name will be used as the R.id.* field name.

The method MAY have multiple parameter :

• A TextView parameter to know which view has targeted this event
• An java.lang.CharSequence parameter to get the modified text.
• An int parameter named start to get the start position of the modified text.
• An int parameter named before to know the text length before modification.
• An int parameter named count to know the number of modified characters.

Examples :

 @TextChange(R.id.helloTextView)
 void onTextChangesOnHelloTextView(CharSequence text, TextView hello, int before, int start, int count) {
        // Something Here
 }
 
 @TextChange
 void helloTextViewTextChanged(TextView hello) {
        // Something Here
 }
 
 @TextChange({R.id.editText, R.id.helloTextView})
 void onTextChangesOnSomeTextViews(TextView tv, CharSequence text) {
        // Something Here
 }
 
 @TextChange(R.id.helloTextView)
 void onTextChangesOnHelloTextView() {
        // Something Here
 }
