【问题标题】:RadioButton color and text color change when selected选中时单选按钮颜色和文本颜色会发生变化
【发布时间】:2017-01-24 15:02:57
【问题描述】:
我该怎么做?
这是我用来改变文字颜色的:
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));
}
}
});
我设置了<item name="android:buttonTint">@color/colorAccent</item>,但未选中的单选按钮是colorAccent,而不是lightGray
有什么想法吗?

【解决方案1】:
要在选择/选中/聚焦时更改文本颜色,请在 android:textColor 中为小部件使用此 colorList:
<?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>
对于按钮的背景,在 android:background 中使用这个:
<?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>
注意color1在文本中作为checked_state的用法,在背景中作为unchecked_state来做对比..
我希望这可能会有所帮助,'。
【解决方案2】:
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>
对单选按钮的选中和未选中状态使用两个可绘制对象
并将上面的选择器用作:
<!-- 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" />
