How to Get string text from multi line EditText
Tag : java , By : Dasharath Yadav
Date : March 29 2020, 07:55 AM
seems to work fine You have to move : st_text = data.getText().toString().trim(); after : int id = item.getItemId(); So ... your code should look like : public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
st_text = data.getText().toString().trim();
if (id == R.id.post) {
if (TextUtils.isEmpty(st_text)){
AlertDialog.Builder builder = new AlertDialog.Builder(CreatePostActivity.this,R.style.AlertDialog);
String titleText = "Error \n ";
ForegroundColorSpan foregroundColorSpan = new ForegroundColorSpan(getResources().getColor(R.color.colorPrimaryDark));
SpannableStringBuilder ssBuilder = new SpannableStringBuilder(titleText);
ssBuilder.setSpan(
foregroundColorSpan,
0,
titleText.length(),
Spanned.SPAN_INCLUSIVE_INCLUSIVE
);
builder.setTitle(ssBuilder);
builder.setCancelable(false);
builder.setPositiveButton("OK", null);
AlertDialog dialog = builder.create();
dialog.setMessage("You can't create empty post");
dialog.show();
return false;
}else {
AlertDialog.Builder builder = new AlertDialog.Builder(CreatePostActivity.this,R.style.AlertDialog);
builder.setTitle("Success");
builder.setMessage("Your post is successfully created.");
builder.setPositiveButton("OK", null);
AlertDialog dialog = builder.create();
dialog.show();
return true;
}
}
return super.onOptionsItemSelected(item);

How to retrieve multi-line text from Edittext?
Date : March 29 2020, 07:55 AM
hope this fix your issue After too much searching and waiting for an answer to this question. I have resolved this issue. Solution: I have measured each and every line & words for preserve this as Multiline text, you can use below function for that. DisplayMetrics metrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);
float density = metrics.density;
String result = fitString(ipText, ipText.getText().toString());
private String fitString(EditText editText, String message) {
Log.i(TAG, "fitString: Default String : " + message);
StringBuilder finalMessage = new StringBuilder();
if (isTooLarge(editText, message)) {
Log.i(TAG, "fitString: isTooLarge 1 : " + true);
List<String> lineList = Arrays.asList(message.split("\n"));
Log.i(TAG, "fitString: stringList" + lineList);
if (lineList != null && lineList.size() > 0) {
for (int i = 0; i < lineList.size(); i++) {
