Android - Alert Dialog Text color change

To change the text color of an AlertDialog in Android, you typically need to create a custom AlertDialog and customize its appearance using a custom layout or programmatically setting styles. Here's how you can achieve this:

Method 1: Custom AlertDialog with a Custom Layout

  1. Create a Custom Layout (custom_dialog.xml):

    Create a layout XML file (res/layout/custom_dialog.xml) where you can define the AlertDialog layout including text views with customized styles.

    <!-- res/layout/custom_dialog.xml --> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:padding="20dp"> <TextView android:id="@+id/dialog_text" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Alert Message" android:textColor="@color/custom_dialog_text_color" android:textSize="16sp" android:gravity="center" android:padding="10dp" /> <!-- Add any other views or buttons as needed --> </LinearLayout>

  2. Create and Customize AlertDialog Programmatically:

    In your activity or fragment, inflate the custom layout and customize the AlertDialog.

    // In your Activity or Fragment AlertDialog.Builder builder = new AlertDialog.Builder(this); LayoutInflater inflater = getLayoutInflater(); View dialogView = inflater.inflate(R.layout.custom_dialog, null); TextView dialogText = dialogView.findViewById(R.id.dialog_text); dialogText.setTextColor(ContextCompat.getColor(this, R.color.custom_dialog_text_color)); // Set custom text color // Set other properties of the AlertDialog as needed builder.setView(dialogView) .setTitle("Custom Dialog Title") .setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // Handle positive button click } }) .setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // Handle negative button click } }); AlertDialog alertDialog = builder.create(); alertDialog.show();

  3. Define Custom Colors:

    Ensure you define your custom colors in res/values/colors.xml:

    <resources> <color name="custom_dialog_text_color">#FF5733</color> </resources>

Method 2: Programmatic Style Application

Alternatively, you can programmatically apply styles to the AlertDialog's TextView directly:

AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage("Alert Message"); AlertDialog alertDialog = builder.create(); alertDialog.show(); // Get the TextView from the AlertDialog TextView messageView = alertDialog.findViewById(android.R.id.message); if (messageView != null) { messageView.setTextColor(getResources().getColor(R.color.custom_dialog_text_color)); }

Notes:

  • Customization: You can further customize the AlertDialog's appearance by adjusting other attributes in the custom layout (custom_dialog.xml), such as background color, text size, padding, etc.

  • Compatibility: Ensure that you handle compatibility with different Android versions. Use ContextCompat.getColor() for color compatibility across different API levels.

By following these steps, you can effectively change the text color of an AlertDialog in Android either by creating a custom layout or programmatically setting styles to meet your application's design requirements. Adjust the colors and styles as per your application's theme and design guidelines.
