選中時，RadioButton顏色和文本顏色會更改

Question

我怎樣才能做到這一點？

這是我用來更改文本顏色的方法：

maleRadioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    maleRadioButton.setTextColor(getApplicationContext().getResources().getColor(R.color.colorPrimary));
                } else {
                    maleRadioButton.setTextColor(getApplicationContext().getResources().getColor(R.color.lightGray));
                }
            }
        });

並且我設置了<item name="android:buttonTint">@color/colorAccent</item> ，但是未選中的單選按鈕是colorAccent而不是lightGray

有任何想法嗎？

custom_radio_button.xml

<?xml version="1.0" encoding="utf-8"?>

    <selector xmlns:android="http://schemas.android.com/apk/res/android">

         <item android:state_checked="true" android:drawable="@drawable/checkedradiobutton" />
         <item android:state_checked="false" android:drawable="@drawable/unchekedradiobutton" />

    </selector>

將兩個可繪制對象用於單選按鈕的選定和未選定狀態

並將以上選擇器用作：

<!--   Customized RadioButtons  -->


              <RadioButton
                   android:id="@+id/radioButtonCustomized1"
                   android:layout_width="fill_parent"
                   android:layout_height="wrap_content"
                   android:text="Radio Button Selected"
                   android:layout_marginTop="20dp"
                   android:checked="true"
                   android:button="@drawable/custom_radio_button"
                   android:textSize="20dp" />

             <RadioButton
                   android:id="@+id/radioButtonCustomized2"
                   android:layout_width="fill_parent"
                   android:layout_height="wrap_content"
                   android:text="Radio Button Not Selected"
                   android:layout_marginTop="10dp"
                   android:checked="false"
                   android:button="@drawable/custom_radio_button"
                   android:textSize="20dp" />

要在選擇/選中/聚焦時更改文本顏色，請在android：textColor中將此colorList用於小部件：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/color1" android:state_focused="true" android:state_pressed="false"/>
    <item android:color="@color/color1" android:state_focused="true" android:state_pressed="true"/>
    <item android:color="@color/color1" android:state_focused="false" android:state_pressed="true"/>
    <item android:color="@color/color1" android:state_checked="true"/>
    <item android:color="@color/color2"/>
</selector>

對於按鈕的背景，請在android：background中使用：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/color2" android:state_checked="true"/>
    <item android:drawable="@color/color2" android:state_pressed="true"/>
    <item android:drawable="@color/color1" android:state_checked="false"/>
</selector>

請注意，color1用作文本中的checked_state和用作背景的unchecked_state以便形成對比。

希望對您有所幫助。
