RadioGroup:RadioButton必须放在RadioGroup的里面,这样才是单选。
选择器在RadioButton中的应用(drawableTop,textColor):
a)图片(不同装态显示不同的图片)
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/ic_sms" android:state_checked="false"></item>
<item android:drawable="@drawable/ic_sms_selected" android:state_checked="true"></item>
</selector>
b)字体颜色(不同状态显示不同的字体颜色)
android:color="#ff669900"//颜色快捷(ctrl+?)搓不出来,需要自己打出来
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:color="#ffffffff" android:state_checked="false"></item>
<item android:color="#ff669900" android:state_checked="true"></item>
</selector>
属性:
<RadioGroup>
android:orientation="horizontal"
<RadioButton>
android:checked="true"
android:button="@null"
android:background="@drawable/start_btn_selector_01"
</RadioButton>
</RadioGroup>
方法:
radioGroup.addView(radioButton);
((RadioButton)radioGroup.getChildAt(int position)).setChecked(true);
int position=radioGroup.indexOfChild(radioButton);
int id=radioGroup.getCheckedRadioButtonId();
RadioButton radioButton=(RadioButton) radioGroup.findViewById(id);
radioButton.getText();
监听器:
radioGroup.setOnCheckedChangeListener();
