Disable/Remove floating label hint text in TextInputLayout XML
Solution 1:
Starting version 23.2.0 of the Support Library you can call
setHintEnabled(false)
or putting it in your TextInputLayout xml as such :
app:hintEnabled="false"
Though the name might makes you think it removes all hints, it just removes the floating one.
Related docs and issue: http://developer.android.com/reference/android/support/design/widget/TextInputLayout.html#setHintEnabled(boolean)
https://code.google.com/p/android/issues/detail?id=181590
Solution 2:
There may be three ways to go about achieving this:
1 Set android:hint
on TextInputLayout
to a space _
character, and keep android:hint="This is my cool hint"
set on the EditText
.
<android.support.design.widget.TextInputLayout
....
....
android:hint=" "> <<----------
<EditText
....
....
android:hint="This is my cool hint"/> <<----------
</android.support.design.widget.TextInputLayout>
This works because TextInputLayout
performs the following check before using the EditText's
hint:
// If we do not have a valid hint, try and retrieve it from the EditText
if (TextUtils.isEmpty(mHint)) {
setHint(mEditText.getHint());
// Clear the EditText's hint as we will display it ourselves
mEditText.setHint(null);
}
By setting android:hint=" "
, if (TextUtils.isEmpty(mHint))
evaluates to false
, and the EditText
retains its hint.
2 Second option would be to subclass TextInputLayout
and override its addView(View child, int index, ViewGroup.LayoutParams params)
method:
public class CTextInputLayout extends TextInputLayout {
public CTextInputLayout(Context context) {
this(context, null);
}
public CTextInputLayout(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public CTextInputLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
public void addView(View child, int index, ViewGroup.LayoutParams params) {
if (child instanceof EditText) {
// cache the actual hint
CharSequence hint = ((EditText)child).getHint();
// remove the hint for now - we don't want TextInputLayout to see it
((EditText)child).setHint(null);
// let `TextInputLayout` do its thing
super.addView(child, index, params);
// finally, set the hint back
((EditText)child).setHint(hint);
} else {
// Carry on adding the View...
super.addView(child, index, params);
}
}
}
Then use your custom CTextInoutLayout
instead of the one from the design support library:
<your.package.name.CTextInputLayout
....
.... > <<----------
<EditText
....
....
android:hint="This is my cool hint"/> <<----------
</your.package.name.CTextInputLayout>
3 Third, and probably the most straight-forward way would be to make the following calls:
// remove hint from `TextInputLayout`
((TextInputLayout)findViewById(R.id.textContainer)).setHint(null);
// set the hint back on the `EditText`
// The passed `String` could also be a string resource
((EditText)findViewById(R.id.myEditText)).setHint("This is my cool hinttt.");
