回答1:
Change it to
tv_edittext = new MyTextView(this);
where MyTextView is :
public class MyTextView extends TextView{
public SampleEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
this.addTextChangedListener(new MyTextWatcher());
}
public SampleEditText(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
this.addTextChangedListener(new MyTextWatcher());
}
public SampleEditText(Context context) {
super(context);
// TODO Auto-generated constructor stub
this.addTextChangedListener(new MyTextWatcher());
}
}
Use a textwatcher as follows:
public class MyTextWatcher implements TextWatcher {
}
No matter how many textviews you dynamically create, a watcher will be created for it and you can get the text being typed in the onTextChanged method of the textwatcher.
