如何修复Umano SlidingPanellayout的扩展高度

Question

我正在尝试修复滑动面板的扩展高度。我想要的是，滑动面板布局只能扩展到屏幕高度的40％或50％。我尝试添加具有值为0.4的umanoanchorpoint属性，但视图仍然可以拖动到全屏。

Answer 1

您可以使用以下滑动侦听器：

slidingUpPanelLayout.addPanelSlideListener(new SlidingUpPanelLayout.PanelSlideListener() {
            @Override
            public void onPanelSlide(View panel, float slideOffset) {
            }
            @Override
            public void onPanelStateChanged(View panel, SlidingUpPanelLayout.PanelState previousState, SlidingUpPanelLayout.PanelState newState) {
                if(newState == SlidingUpPanelLayout.PanelState.EXPANDED) slidingUpPanelLayout.setPanelState(SlidingUpPanelLayout.PanelState.ANCHORED);
            }
        });

或也许：

slidingUpPanelLayout.addPanelSlideListener(new SlidingUpPanelLayout.PanelSlideListener() {
            @Override
            public void onPanelSlide(View panel, float slideOffset) {
                if(slideOffset > desiredOffset) slidingUpPanelLayout.setPanelState(SlidingUpPanelLayout.PanelState.ANCHORED);
            }
            @Override
            public void onPanelStateChanged(View panel, SlidingUpPanelLayout.PanelState previousState, SlidingUpPanelLayout.PanelState newState) {
            }
        });
