android中的单选和多选按钮的使用

1.布局文件：

	<RadioGroup android:layout_width="wrap_content"
	    		android:layout_height="wrap_content"
	    		android:orientation="vertical"
	    		android:id="@+id/radioGroup">
	    <RadioButton android:layout_width="wrap_content"
	        		android:layout_height="wrap_content"
	        		android:id="@+id/radio1"
	        		android:text="@string/female"/>
	    <RadioButton android:layout_width="wrap_content"
	        		android:layout_height="wrap_content"
	        		android:id="@+id/radio2"
	        		android:text="@string/male"/>
	</RadioGroup>
	<CheckBox android:id="@+id/singBox"
	    	android:layout_width="wrap_content"
	    	android:layout_height="wrap_content"
	    	android:text="@string/sing"/>
	<CheckBox android:id="@+id/runBox"
	    	android:layout_width="wrap_content"
	    	android:layout_height="wrap_content"
	    	android:text="@string/run"/>
	<CheckBox android:id="@+id/danceBox"
	    	android:layout_width="wrap_content"
	    	android:layout_height="wrap_content"
	    	android:text="@string/dance"/>
