检查 SlidingUpPanel 状态的监听器

Listener for checking the state of SlidingUpPanel

我想在 AndroidSlidingUpPanel 展开到全屏时更改项目的可见性 screen.Is 是否有检测滑动面板是否全屏的侦听器?我尝试使用它但没有用-

slidingPaneLayout.setOnDragListener(new View.OnDragListener() {
            @Override
            public boolean onDrag(View v, DragEvent event) {
                if(slidingPaneLayout.getPanelHeight()>700)
                belowarrow.setVisibility(View.GONE);
                return true;
            }
        });
 slidingPaneLayout.setPanelSlideListener(new SlidingUpPanelLayout.PanelSlideListener() {
            @Override
            public void onPanelSlide(View view, float v) {

            }

            @Override
            public void onPanelCollapsed(View view) {

              //here collapse
            }

            @Override
            public void onPanelExpanded(View view) {
                //here it is in fullscreen
            }

            @Override
            public void onPanelAnchored(View view) {

            }

            @Override
            public void onPanelHidden(View view) {

            }
        });

给你,希望对你有所帮助
