Change checkbox text color when checked
I'm not sure why there isn't mentioned setting the text color through xml. If you create text_my_checked.xml like @Eugen mentioned. You are able to set it in xml like this
<CheckBox
android:id="@+id/checkbox"
android:layout_width="20dp"
android:layout_height="20dp"
android:background="@drawable/states"
android:gravity="center_horizontal|center_vertical"
android:button="@null"
android:textColor="@drawable/text_my_checked"
android:text="test/>
You can use selector as well but instead of /res/drawable
put it in /res/color
.
/res/color/text_my_checked.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="#ffcc00"/> <!-- checked -->
<item android:color="#ffffff"/> <!-- anything else -->
</selector>
You would get this color as ColorStateList
by calling getResources().getColorStateList(R.color.text_my_checked)
.
EDIT:
Ever since appcompat-v7 24.0.0 we can use theme references in color state lists on platforms down to API 9. This was originally introduced in API 23.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="?colorControlActivated"/> <!-- checked -->
<item android:state_checked="true" android:state_enabled="false" app:alpha="?android:disabledAlpha" android:color="?colorControlActivated"/> <!-- checked, disabled -->
<item android:color="?android:textColorPrimary"/> <!-- anything else -->
</selector>
Call AppCompatResources.getColorStateList(checkbox.getContext(), R.color.text_my_checked)
to obtain the color state list.
You might do that programmatically, recalling your Checkbox
and setting an onCheckedChangeListener
.
CheckBox cb = (CheckBox) findViewById(R.id.checkbox);
cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) { buttonView.setTextColor(...) }
if (!isChecked) { buttonView.setTextColor(...); }
}
});
