在我的活动中,我有标记的地图。当用户单击标记时,它会显示有关底部工作表的位置的详细信息。
当视图第一次填充有关地点的数据时,它可以正常工作。但是在隐藏了底片之后,再次点击后再显示它就无法正常工作:
TextView保存旧高度(view.invalidate()
不起作用)。
viewGroup.addView
方法不起作用(在添加之前调用viewGroup.removeAllViews()
,但它保持旧的高度并且添加视图不起作用。)
但是当我在不隐藏/显示bottomSheet的情况下更改视图数据时,所有内容都能正常工作。喜欢第一次改变。
我在调试时也看到了其他奇怪的行为:我有了linearLayout,它有4个relativeLayouts(里面有textView和imageView)。当我改变一两个的可见性(消失/可见)时,即使linearLayout具有垂直方向,它们也会相互重叠。但并非总是如此,就像上面一样:第一次工作没问题,其他时候如果我在看不到bottomSheet时改变视图就不能正常工作(如上所述),但是当bottomBehavior可见时如果我改变了视图它可以正常工作(比如第一次)时间)。
如果我没弄错的话,那是因为底片。因为我以前在Android上看不到这种观点行为。
我的代码:
mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheetView);
mBottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
switch (newState) {
case BottomSheetBehavior.STATE_HIDDEN:
hidePlaceDetails();
break;
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
}
});
/**

*
* @param place the place
*/
private void showPlaceDetails(Place place) {
placeTitleView.setText(place.getTitle());
placeCategoryView.setText(place.getParentTitle());
placeInfoGroup.removeAllViews();
addPlaceInfo(R.drawable.ic_info, place.getDescription(), null);
addPlaceInfo(R.drawable.ic_place, place.getAddress(), null);
addPlaceInfo(R.drawable.ic_phone, place.getPhoneNumbers(), null);
addPlaceInfo(R.drawable.ic_language, place.getWebsite(), null);
Photo photo = place.getPhoto();
if (U.isEmpty(photo.getImagePath())) {
U.hideView(placePhotoView);
} else {
U.showView(placePhotoView);
int proportionalHeight = U.calculateProportionalHeight(
screenSize[0] /*screenWidth*/,
photo.getWidth(),
photo.getHeight(),
800 /*maxHeight*/);
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
proportionalHeight
);
placePhotoView.setLayoutParams(layoutParams);
ImageUtils.networkImage(this, photo, placePhotoView, null, U.imagePlaceholder());
}
U.view(placeDistanceProgressView, true); //showView
U.view(placeDistanceView, false); //hideView
if (mMap.getMyLocation() != null) {
Waypoint myLocation = new Waypoint(mMap.getMyLocation().getLongitude(), mMap.getMyLocation().getLatitude());
Waypoint destination = new Waypoint(place.getPosition().getLongitude(), place.getPosition().getLatitude());
getAndDrawRoute(place, myLocation, destination);
}
int thirdScreen = screenSize[1] / 3;
mMap.setPadding(0, 0, 0, halfScreen);
isShowingPlaceDetails = true;
mBottomSheetBehavior.setPeekHeight(halfScreen);
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
/**

*/
private void hidePlaceDetails() {
mMap.setPadding(0, 0, 0, 0);
mBottomSheetBehavior.setPeekHeight(0);
mBottomSheetBehavior.setHideable(true);
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_HIDDEN);
addMarkers();
isShowingPlaceDetails = false;
}
/**

titleView.setText(U.notEmpty(title) ? title : Html.fromHtml(String.format("<i>%s</i>", "None")));

我很难解释这一点,但这个问题让我疯狂了几天。非常感谢您提供的任何帮助!
答案 0 :(得分:2)
我通过以下解决方法解决了类似的问题。
在我的BottomSheetCallback
中,我添加了以下内容:
behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(final View bottomSheet, int newState) {
switch (newState) {
case BottomSheetBehavior.STATE_COLLAPSED:
case BottomSheetBehavior.STATE_EXPANDED:
bottomSheet.post(new Runnable() {
@Override
public void run() {
bottomSheet.requestLayout(); // this seems to fix it.
}
});
break;
case BottomSheetBehavior.STATE_HIDDEN:
// remove the views here with removeAllViews();
break;
}
}
@Override
public void onSlide(View bottomSheet, float slideOffset) {
}
});
它仍然不完美,因为新的布局需要一些时间来渲染,并且视图会有一些延迟。但总比没有好。
此外,如果您已经支持目标24,那么在最新的支持lib 24.0.0中似乎有一个错误修正
