Programmatically Set Edit Text Hint in Android?

Did you try the setHint?

myTextView.setHint("My conditional hint");

Hope it helps..

If you are using simple Editext without TextInputLayout :

EditText etUsername;
etUsername = (EditText) findViewById(R.id.etUsername);
etUsername.setHint("Your Hint");

If you are using Editext within TextInputLayout then you need to change property of TextInputLayout not Edittext:

TextInputLayout layoutUser;
layoutUser = (TextInputLayout) findViewById(R.id.inputLayoutUname);
layoutUser.setHint(getResources().getString(R.string.hintFaculty));

Call setHint() on the EditText.

((TextView) findViewById(R.id.yourEditTextId)).setHint("hint text");

Kotlin

editText.hint = "Your hint"

if you are using actionbarsherlock searchview, this is the best way to set string dynamically

   AutoCompleteTextView searchTextView =
                    (AutoCompleteTextView) mSearchView.findViewById(R.id.abs__search_src_text);

searchTextView.setHint(getResources().getString(R.string.search));

for editText.hint you must delete name of your edit.Text from activity_main.xml then set in the MainActivity in java or activity_main.xml because text is preferred to hint.

 <EditText
     android:id="@+id/text"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:inputType="textMultiLine|textLongMessage"
     android:hint="\n"/>

To be honest I don´t understand why.. but including "\n" as hint in the xml did the trick!

Now you can call setHint from Java code:

searchEditText.setHint(getString(R.string.search_hint));

and remove the \n from strings.xml if you want to allow the text split automatically according to the room

<string name="search_hint">keyword, location, max price (e.g. 1K, 1M)</string>

In Kotlin

val layoutMobile: TextInputLayout = findViewById<View>(R.id.inputLayout_MobileNumber) as TextInputLayout
        layoutMobile.hint = "Your Hint"

in Java

yourEditTex.setText("");//First
yourEditTex.hit("Your text");

this for alls cases.
