Android - change font for editText hint

To change the font of the hint text in an EditText in Android, you can achieve this by creating a custom style and applying it to the EditText. Android doesn't directly support setting a custom font for hint text in XML like it does for regular text, so you'll need to use a workaround. Here's how you can do it programmatically:

Step-by-Step Implementation:

  1. Define Custom Font in res/font Directory:

    Place your custom font file (e.g., custom_font.ttf) in the res/font directory. If the font directory does not exist, create it under res.

  2. Create a Custom Style for the Hint Text:

    Define a custom style in res/values/styles.xml for the hint text:

    <style name="HintText"> <item name="android:fontFamily">@font/custom_font</item> <!-- Other attributes you want to apply to the hint text --> </style>

    Replace custom_font with the name of your font file (without the extension).

  3. Apply the Custom Style Programmatically:

    In your activity or fragment where you have the EditText, apply the custom style to the hint text:

    import android.graphics.Typeface; import android.os.Bundle; import android.widget.EditText; public class MainActivity extends AppCompatActivity { private EditText editText; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); editText = findViewById(R.id.editText); // Get the custom font from the resources Typeface typeface = getResources().getFont(R.font.custom_font); // Apply the custom font to the hint text editText.setTypeface(typeface); } }

    Replace R.font.custom_font with the actual reference to your custom font.

  4. Apply the Style to the EditText in XML:

    In your layout XML (activity_main.xml or wherever your EditText is defined), apply the custom style to the EditText:

    <EditText android:id="@+id/editText" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Your Hint Text" style="@style/HintText" />

    Ensure style="@style/HintText" references the style you defined (HintText) in styles.xml.

Notes:

  • Compatibility: This approach is compatible with Android devices running API 16 (Jelly Bean) and above.

  • Customization: Adjust the HintText style in styles.xml with additional attributes like android:textColor, android:textSize, etc., as per your design requirements.

  • Font Resources: Ensure your font file (custom_font.ttf) is correctly placed in the res/font directory and referenced in styles.xml and Java code.

By following these steps, you can change the font of the hint text in an EditText in Android using a custom font. This method provides flexibility in styling the hint text to match your application's design guidelines.

Examples

  1. How to Set Custom Font for EditText Hint in XML

    <EditText android:id="@+id/editText" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Enter text here" android:textSize="16sp" android:fontFamily="@font/my_custom_font" />

    Description: This code demonstrates how to set a custom font for the hint text in an EditText directly in the XML layout.

  2. Change EditText Hint Font Programmatically

    EditText editText = findViewById(R.id.editText); Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/my_custom_font.ttf"); editText.setTypeface(typeface); editText.setHint("Enter text here");

    Description: This example shows how to change the font of the hint programmatically by loading a custom font from the assets folder.

  3. Using SpannableString for Custom EditText Hint

    EditText editText = findViewById(R.id.editText); SpannableString hint = new SpannableString("Enter text here"); hint.setSpan(new TypefaceSpan("my_custom_font"), 0, hint.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); editText.setHint(hint);

    Description: This code snippet uses SpannableString to set a custom font for the hint text.

  4. Creating a Custom EditText Class for Hint Font

    public class CustomEditText extends AppCompatEditText { public CustomEditText(Context context, AttributeSet attrs) { super(context, attrs); applyCustomFont(context); } private void applyCustomFont(Context context) { Typeface typeface = Typeface.createFromAsset(context.getAssets(), "fonts/my_custom_font.ttf"); setTypeface(typeface); } }

    Description: This custom EditText class applies a custom font to the hint in its constructor.

  5. Changing Hint Color and Font Together

    <EditText android:id="@+id/editText" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Enter text here" android:hintTextColor="@android:color/darker_gray" android:textColorHint="@android:color/holo_blue_light" android:fontFamily="@font/my_custom_font" />

    Description: This XML snippet sets a custom font and color for the hint text of the EditText.

  6. Setting Hint Font with Styles

    <style name="CustomEditTextStyle"> <item name="android:fontFamily">@font/my_custom_font</item> <item name="android:textColorHint">@android:color/holo_red_dark</item> </style> <EditText android:id="@+id/editText" style="@style/CustomEditTextStyle" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Enter text here" />

    Description: This code defines a style that sets the font and hint color for EditText, applied directly in the XML.

  7. Using Custom Typeface with TextWatcher

    EditText editText = findViewById(R.id.editText); Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/my_custom_font.ttf"); editText.setTypeface(typeface); editText.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) {} @Override public void onTextChanged(CharSequence s, int start, int before, int count) { if (s.length() == 0) { editText.setHint("Enter text here"); } } @Override public void afterTextChanged(Editable s) {} });

    Description: This example uses TextWatcher to change the hint dynamically based on the text input while maintaining the custom font.

  8. Adjusting Hint Size and Font Programmatically

    EditText editText = findViewById(R.id.editText); editText.setHint("Enter text here"); editText.setHintTextColor(Color.GRAY); editText.setTextSize(TypedValue.COMPLEX_UNIT_SP, 14); Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/my_custom_font.ttf"); editText.setTypeface(typeface);

    Description: This code snippet sets the hint text, color, size, and font programmatically.

  9. Using XML Attribute for Custom Font in EditText

    <EditText android:id="@+id/editText" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Enter text here" app:fontFamily="@font/my_custom_font" />

    Description: This XML code uses a custom attribute to specify the font for the hint in EditText.

  10. Changing Hint Font Dynamically on User Action

    EditText editText = findViewById(R.id.editText); Button changeFontButton = findViewById(R.id.changeFontButton); changeFontButton.setOnClickListener(v -> { Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/another_custom_font.ttf"); editText.setTypeface(typeface); });

    Description: This example demonstrates how to change the font of the EditText hint when a button is clicked.
