How set gray text to EditText Android example


AD MOB

Example source code for Android development. How set gray text to EditText when EditText is blank.
Hint text to display when the text is empty.
In layout/main.xml insert to EditText row Attribute Name android:hint="Some text"


<EditText
        android:id="@+id/myEdit" 
	android:layout_height="wrap_content" android:layout_width="fill_parent"
        android:hint="Some text"
	android:singleLine="true"
</EditText>	



Programatically you can use method setHint:


// setHint(CharSequence hint) example
(EditText)findViewById(R.id.myEdit).setHint("My text");
// or int resId as method setHint(int resId) 
EditText myEdit = findViewById(R.id.myEdit);
myEdit.setHint(R.string.app_name);
