android webview控件的缩放问题 隐藏缩放控件

利用java的反射机制

public void setZoomControlGone(View view) {
Class classType;
Field field;
try {
classType = WebView.class;
field = classType.getDeclaredField("mZoomButtonsController");
field.setAccessible(true);
ZoomButtonsController mZoomButtonsController = new ZoomButtonsController(
view);
mZoomButtonsController.getZoomControls().setVisibility(View.GONE);
try {
field.set(view, mZoomButtonsController);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
} catch (SecurityException e) {
e.printStackTrace();
} catch (NoSuchFieldException e) {
e.printStackTrace();
}
}
