버튼이 클릭되면 테이크 픽처에서 미디어스캐너연결 메소드가 실행됩니고 미디어에컨넥션이 끝나게되면 해당 액티비티로 이동하게됩니다 그러면 그액티미비 xml 상의 " Textview만
넣었을경우 텍스트는 잘 출력" 이됩니다. 하지만 이미지뷰를 선언하고
public class ImagePhotoView extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.imagephotoview);
// TODO Auto-generated method stub
ImageView iv = (ImageView)findViewById(R.id.lv);
iv.setImageResource(R.drawable.ic_launcher);
}
해당 엑티비티에 선언하고 돌리면
