答案 0 :(得分:23)
在res / values文件夹中创建名为colors.xml的xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="red">#ff0000</color>
<color name="green">#00ff00</color>
</resources>
在drawable文件夹中,创建一个xml文件my_btn_toggle.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="false" android:drawable="@color/red" />
<item android:state_checked="true" android:drawable="@color/green" />
</selector>
并在xml部分定义切换按钮:
<ToggleButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New ToggleButton"
android:id="@+id/toggleButton"
android:background="@drawable/my_btn_toggle"/>

ToggleButton Btn=new ToggleButton(this);// or get it from the layout by ToggleButton Btn=(ToggleButton) findViewById(R.id.IDofButton);
Btn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(isChecked)
buttonView.setBackgroundColor(Color.GREEN);
else buttonView.setBackgroundColor(Color.RED);
}
});
