Change font of the floating label EditText and TextInputLayout

Question

Someone tried to change the font of the floating label? I changed the source of EditText but the font of the floating label did not change, I am very grateful to those who help me

Code:

               <android.support.design.widget.TextInputLayout
                    android:id="@+id/tilTextoDescricao"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:layout_toRightOf="@id/tilValorUnidade"
                    android:layout_marginTop="10dp">

                    <EditText
                        android:id="@+id/etTextoDescricao"
                        android:layout_width="fill_parent"
                        android:layout_height="wrap_content"
                        android:layout_marginLeft="5dp"
                        android:hint="Descrição"
                        android:textSize="15dp"
                        android:inputType="text" />

                </android.support.design.widget.TextInputLayout>

----------------- 

   etTextoDescricao= (EditText) findViewById(R.id.etTextoDescricao);
  etTextoDescricao.setTypeface(CustomTypeface.getTypefaceMediumDefault(this));

Answer 1

As of Design Library v23, you can use TextInputLayout#setTypeface().

This will set the typeface on both the expanded and floating hint.

Here is the feature request where it was discussed on b.android.com.

EDIT: The error view typeface was not being set, but is now fixed in v25.1.0.

Answer 2

Unfortunately, you'll have to use reflection to handle this.

The floating label is drawn by CollapsingTextHelper, which is an internal, package-private class and isn't setup to handle spans. So, using something like a custom TypefaceSpan won't work in this case.

Because this uses reflection, it isn't guaranteed to work in the future.

Implementation

final Typeface tf = Typeface.createFromAsset(getAssets(), "your_custom_font.ttf");
final TextInputLayout til = (TextInputLayout) findViewById(R.id.yourTextInputLayout);
til.getEditText().setTypeface(tf);
try {
    // Retrieve the CollapsingTextHelper Field
    final Field cthf = til.getClass().getDeclaredField("mCollapsingTextHelper");
    cthf.setAccessible(true);

    // Retrieve an instance of CollapsingTextHelper and its TextPaint
    final Object cth = cthf.get(til);
    final Field tpf = cth.getClass().getDeclaredField("mTextPaint");
    tpf.setAccessible(true);

    // Apply your Typeface to the CollapsingTextHelper TextPaint
    ((TextPaint) tpf.get(cth)).setTypeface(tf);
} catch (Exception ignored) {
    // Nothing to do
}

Error view

If you needed to change the font of the error, you could do one of two things:

1. Use Reflection grab the error TextView and apply the Typeface much like before
2. Use a custom span. Unlike the floating label, the error view used by TextInputLayout is just a TextView, so it's able to handle spans.

Using reflection

final Field errorField = til.getClass().getDeclaredField("mErrorView");
errorField.setAccessible(true);
((TextView) errorField.get(til)).setTypeface(tf);

Using a custom span

final SpannableString ss = new SpannableString("Error");
ss.setSpan(new FontSpan(tf), 0, ss.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
til.setError(ss);

private static final class FontSpan extends MetricAffectingSpan {

    private final Typeface mNewFont;

    private FontSpan(Typeface newFont) {
        mNewFont = newFont;
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        ds.setTypeface(mNewFont);
    }

    @Override
    public void updateMeasureState(TextPaint paint) {
        paint.setTypeface(mNewFont);
    }

}

Results

The font I'm using is Smoothie Shoppe.

I'm using new MaterialComponents theme and none of the answers helped me.

Had to play with styles and themes on my own. Will post a chunk of styles here in case somebody faces the same issue.

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
  ...
  <item name="textInputStyle">@style/CustomFontTextInputLayout</item>
</style>  

<!-- region TextInputLayout & TextInputEditText styles -->
<style name="TextInputLayout.OutlineBox.CustomFont" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
  <item name="android:theme">@style/ThemeOverlay.TextInputEditText.OutlinedBox.CustomFont</item>
</style>

<style name="ThemeOverlay.TextInputEditText.OutlinedBox.CustomFont" parent="ThemeOverlay.MaterialComponents.TextInputEditText.OutlinedBox">
  <item name="editTextStyle">@style/TextInputEditText.OutlinedBox.CustomFont</item>
</style>

<style name="TextInputEditText.OutlinedBox.CustomFont" parent="Widget.MaterialComponents.TextInputEditText.OutlinedBox">
  <item name="android:fontFamily">@font/my_font</item>
</style>

<style name="CustomFontTextInputLayout" parent="Widget.Design.TextInputLayout">
  <item name="hintTextAppearance">@style/TextInputLayoutHintText</item>
  <item name="helperTextTextAppearance">@style/TextInputLayoutHelperText</item>
  <item name="errorTextAppearance">@style/TextInputLayoutErrorText</item>
</style>

<style name="TextInputLayoutHintText" parent="TextAppearance.Design.Hint">
  <item name="android:fontFamily">@font/my_font</item>
</style>

<style name="TextInputLayoutHelperText" parent="TextAppearance.Design.HelperText">
  <item name="android:fontFamily">@font/my_font</item>
</style>

<style name="TextInputLayoutErrorText" parent="TextAppearance.Design.Error">
  <item name="android:fontFamily">@font/my_font</item>
</style>
<!-- endregion -->

Then in xml layout:

<android.support.design.widget.TextInputLayout
    style="@style/TextInputLayout.OutlineBox.CustomFont"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.design.widget.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/first_name"/>
</android.support.design.widget.TextInputLayout>

Here's the result:

i just found a simple solution and it's worked for me:

in this way you can set the typeface to hint of any edit text:

in layout.xml :

 <android.support.design.widget.TextInputLayout
            android:id="@+id/text_input1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
            <EditText
                android:id="@+id/edt_user"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="@string/username"/>
        </android.support.design.widget.TextInputLayout>

and in java class :

public class MainActivity extends AppCompatActivity {

EditText editText;
TextInputLayout textInputLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Typeface font_yekan= Typeface.createFromAsset(getAssets(), "fonts/byekan.ttf");
        textInputLayout= (TextInputLayout) findViewById(R.id.text_input1);
    textInputLayout.setTypeface(font_yekan);
      }
 }

Answer 5

Here is a custom class implementation for adneal's answer.

public class CustomTextInputLayout extends TextInputLayout {

    public CustomTextInputLayout(Context context) {
        super(context);
        initFont(context);
    }

    public CustomTextInputLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
        initFont(context);
    }

    private void initFont(Context context) {
        final Typeface typeface = Typeface.createFromAsset(
                context.getAssets(), "fonts/YOUR_CUSTOM_FONT.ttf");

        EditText editText = getEditText();
        if (editText != null) {
            editText.setTypeface(typeface);
        }
        try {
            // Retrieve the CollapsingTextHelper Field
            final Field cthf = TextInputLayout.class.getDeclaredField("mCollapsingTextHelper");
            cthf.setAccessible(true);

            // Retrieve an instance of CollapsingTextHelper and its TextPaint
            final Object cth = cthf.get(this);
            final Field tpf = cth.getClass().getDeclaredField("mTextPaint");
            tpf.setAccessible(true);

            // Apply your Typeface to the CollapsingTextHelper TextPaint
            ((TextPaint) tpf.get(cth)).setTypeface(typeface);
        } catch (Exception ignored) {
            // Nothing to do
        }
    }
}

In your XML files now you need to use CustomTextInputLayout instead of TextInputLayout and it will work out of the box.

<your.package.CustomTextInputLayout
    android:id="@+id/textInputLayout_email"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <AutoCompleteTextView
        android:id="@+id/editText_email"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/hint_email"
        android:inputType="textEmailAddress" />

Thanks adneal for the answer.

Answer 6

final Typeface tf = Typeface.createFromAsset(getAssets(), "your_custom_font.ttf");
final TextInputLayout til = (TextInputLayout) findViewById(R.id.yourTextInputLayout);
til.getEditText().setTypeface(tf);
til.setTypeface(tf);

Answer 7

There is a simpler way,

Create a new directory in your 'res' folder named 'font' and put a font in there. Then open your 'styles' file and create a new style :

<style name="customfontstyle" parent="@android:style/TextAppearance.Small">
        <item name="android:fontFamily">@font/poppins_regular</item>
    </style>

You can add more properties as well, such as textColor, textSize etc..

Then in your XML:

<android.support.design.widget.TextInputLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:hintTextAppearance="@style/customfontstyle"
       >

        <android.support.design.widget.TextInputEditText
            android:layout_width="220dp"
            android:layout_height="wrap_content"
            android:id="@+id/edit_phone_number"
            android:hint="@string/phone_number_label"

            android:inputType="number"
            />
    </android.support.design.widget.TextInputLayout>

I checked it and it works.

Answer 8

fixing a problem in @adneal answer: if setErrorEnabled is not set true, mErrorView would be null and if you set it false at any point the font would change back to default. so to fix it:

in you custom TextInputLayout override setErrorEnabled

@Override
public void setErrorEnabled(boolean enabled) {

    super.setErrorEnabled(enabled);

    if (enabled) {

        try {

            Field cthf = TextInputLayout.class.getDeclaredField("mErrorView");
            cthf.setAccessible(true);

            TextView error = (TextView) cthf.get(this);

            if (error != null)
                error.setTypeface(tf);


        } catch (Exception e) {

        }
    }
}

Answer 9

I was looking for this, I found this way, using the support library:

Typeface typeface = ResourcesCompat.getFont(context, R.font.myfont);

and set this typeface to yout TextInpuLayout.

For me works like charm, I hope it helps others =]

Answer 10

This is how i achieve this

edit_login_emailOrPhone.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus)
            {
                textInputLayout_login_emailOrPhone.setTypeface(APSApplication.getInstance().getFonts().getTypefaceSemiBold());
            }else
            {
                textInputLayout_login_emailOrPhone.setTypeface(APSApplication.getInstance().getFonts().getTypefaceRegular());
            }
        }
    });

Answer 11

Use can use style.xml like below:

Style file:

<style name="TextInputLayoutErrorStyle" parent="TextAppearance.Design.Error">
    <item name="fontFamily">@font/iran_sans_medium</item>
    <item name="android:fontFamily">@font/iran_sans_medium</item>
</style>

<style name="TextInputLayoutHintStyle" parent="TextAppearance.Design.Hint">
    <item name="fontFamily">@font/iran_sans_medium</item>
    <item name="android:fontFamily">@font/iran_sans_medium</item>
</style>

<style name="TextInputLayoutHelperStyle" parent="TextAppearance.Design.HelperText">
    <item name="fontFamily">@font/iran_sans_medium</item>
    <item name="android:fontFamily">@font/iran_sans_medium</item>
</style>

<style name="TextInputLayoutOutlinedBoxStyle" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
    <item name="helperTextTextAppearance">@style/TextInputLayoutHelperStyle</item>
    <item name="errorTextAppearance">@style/TextInputLayoutErrorStyle</item>
    <item name="hintTextAppearance">@style/TextInputLayoutHintStyle</item>
</style>

Layout file:

<com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_centerInParent="true"
            android:hint="@string/cardname_hint"
            android:layout_marginStart="30dp"
            android:layout_marginEnd="30dp"
            card_view:helperText="@string/cardname_helper"
            style="@style/TextInputLayoutOutlinedBoxStyle"
            android:layout_height="wrap_content">

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:fontFamily="@font/iran_sans_medium"
                android:textColor="@color/colorTextPrimary"
                android:layout_height="wrap_content" />
