I am using an EditText
. Is it possible to have a part of text uneditable and the rest editable in the same EditText
?

You could use
editText.setFocusable(false);
or
editText.setEnabled(false);
although disabling the EditText
does currently not ignore input from the on-screen keyboard (I think that's a bug).
Depending on the application it might be better to use an InputFilter
that rejects all changes:
editText.setFilters(new InputFilter[] {
new InputFilter() {
public CharSequence filter(CharSequence src, int start,
int end, Spanned dst, int dstart, int dend) {
return src.length() < 1 ? dst.subSequence(dstart, dend) : "";
}
}
});
Also see this question.

2For show/hide password fields, the text content is cleared if you use this trick and then change the input type (`editText.setInputType(InputType.TYPE_CLASS_TEXT|InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD)`). The workaround is to temporarily set the filters to the empty array while you change the input type. – David Leonard Nov 11 '10 at 09:28

You can implement a TextChangedListener where you make sure those parts of your text wont get deleted/overwritten
.
class TextChangedListener implements TextWatcher {
public void afterTextChanged(Editable s) {
makeSureNothingIsDeleted();
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence s, int start, int before, int count) {}
}
TextChangedListener tcl = new TextChangedListener();
my_editable.addTextChangedListener(tcl);
