android – How to center text into radio button

Questions:

I have customized the original radiobutton with a specific background and by removing the button :

styles.xml :

<style name="echelle_relecture">
    <item name="android:background">@drawable/btn_relecture_echelle</item>
    <item name="android:button">@null</item>
    <item name="android:layout_gravity">center_horizontal</item>
</style>

radio.xml :

<RadioGroup android:layout_height="wrap_content" android:id="@+id/radioGroup1" android:layout_width="fill_parent" android:orientation="horizontal" android:layout_marginTop="10dp">
        <RadioButton style="@style/echelle_relecture" android:text="@string/day" android:id="@+id/jour" android:checked="true"></RadioButton>
        <RadioButton style="@style/echelle_relecture" android:text="@string/hour" android:id="@+id/hour" android:button="@null"></RadioButton>
        <RadioButton style="@style/echelle_relecture" android:text="@string/min" android:id="@+id/mins" android:button="@null" android:enabled="false"></RadioButton>
</RadioGroup>

Despite the “center_horizontal” parameter i can’t get the text centered inside the button. How can i do that ?

How to&Answers:

You should use gravity, not layout_gravity to centralize text inside RadioButton.

Answer:

use this

android:gravity="center"

Answer:

<RadioButton
    ...
    android:textAlignment="center"
    ... />

Answer:

Either setting android:paddingLeft="0dp" or android:paddingRight="0dp" should work to center the text

Answer:

add the code in your style

<item name="android:gravity">center</item>
