안녕하세요.. Android-Zoom-View API를 사용하고 있는데 문제점이 있어서 질문을 드립니다.
LinearLayout에 AddviEw를 통해 웹뷰를 올리고 ZoomView에 올렸는데 첫페이지 이후로 보이지는 않네요...
확대를 하면 아럐쪽으로 가긴 가는데 확대가 안된 상태에서는 도무지 방법이 보이지 않아서 질문 드립니다ㅠ
소스입니다.
Main
LinearLayout ly = new LinearLayout(this);
LayoutParams params = new LayoutParams(android.widget.LinearLayout.LayoutParams.MATCH_PARENT,
android.widget.LinearLayout.LayoutParams.MATCH_PARENT);
ly.setLayoutParams(params);
ly.setOrientation(LinearLayout.VERTICAL);
mainLinearLayout = ly;
// sv.addView(ly);
//줌뷰 객체 생성후
zoomView = new ZoomView(this);
//줌컨텐츠를 줌뷰에 넣어준다
zoomView.addView(ly);
//줌뷰를 컨테이너에 붙여준다
FrameLayout main_container = (FrameLayout)
findViewById(R.id.createConsentnote_root);
main_container.addView(zoomView,0);
ZoomView (Maximum에 걸려서 계산하는쪽만 올려봅니다)
