I have an EditText widget in an Activity which creates text chip when the user presses space when typing. I save the result in comma separated values and store it in the database.
Now I'm trying to create another Activity which gets the data from the database and edit it. The max I'm able to do is set the text in the EditText.
.
I'm stuck here. I'm able to create chips when the user types but not by code. What should I do to get the desired behavior?
My Code Below:
edt.setText("Europe USA London Spain");
edt.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(final CharSequence s, int arg1, int arg2, int arg3) {
String addedString = s.toString();
if (addedString.length() > 0 && addedString.endsWith(" ")) {
if (!isTextAdditionInProgress) {
// something is added
edt.setCursorVisible(true);
int startIndex = isContactAddedFromDb ? addedString.length() : edt.getSelectionEnd();
startIndex = startIndex < 1 ? 1 : startIndex;
isTextAdditionInProgress = true;
addOrCheckSpannable(s, startIndex);
}
stringLength = addedString.length();
} else {
Log.v("", "Doesn't contain space, good to go!");
}
}
@Override
public void beforeTextChanged(CharSequence s, int arg1, int arg2, int arg3) {
beforeChangeIndex = edt.getSelectionStart();
changeString = s.toString();
}
@Override
public void afterTextChanged(Editable s) {
if (!isTextDeletedFromTouch && s.toString().length() < changeString.length() && !isTextAdditionInProgress) {
String deletedString = "";
try {
deletedString = changeString.substring(afterChangeIndex, beforeChangeIndex);
} catch (Exception e) {
}
if (deletedString.length() > 0 && deletedString.contains(","))
deletedString = deletedString.replace(",", "");
}
}
});
public void addOrCheckSpannable(CharSequence s, int startIndex) {
boolean checkSpannable = false;
String overallString;
if (s == null) {
checkSpannable = true;
s = edt.getText();
startIndex = edt.getSelectionEnd();
startIndex = startIndex < 1 ? 1 : startIndex;
// startIndex =-1;
overallString = edt.toString();
if (TextUtils.isEmpty(overallString.trim()))
return;
} else {
overallString = s.toString();
startIndex = startIndex - 1;
}
int spanEnd = 0;
for (int i = startIndex - 1; i >= 0; i--) {
Character c = overallString.charAt(i);

// has span
