어느 예제를 봐도 라디오버튼을 체크하고 버튼을 눌러야 실행되는 거더라구요
근데 버튼없이 라디오 버튼을 체크만해도 이미지가 바뀔 수 있도록 하는 건 어떻게 하나요?
소스 드릴게요~
먼저 main.xml
<LinearLayout xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:orientation="vertical" >
<EditText
android:id="@+id/edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</EditText>
<Button
android:id="@+id/btn1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="글자 나타내기" >
</Button>
<Button
android:id="@+id/btn2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="홈페이지 열기" >
</Button>
<RadioGroup
android:id="@+id/radioGroup1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<RadioButton
android:id="@+id/radio1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="진저브래드" />
<RadioButton
android:id="@+id/radio2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="아이스크림 샌드위치" />
</RadioGroup>
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" />
</LinearLayout>
