侦听器用于检查SlidingUpPanel的状态

Question

我希望在AndroidSlidingUpPanel扩展到全屏时更改项目的可靠性。是否有任何侦听器检测滑动面板是否全屏？我尝试使用此功能但没有工作 - < / p>

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

Answer 1

 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) {

            }
        });

在这里，我希望它会有所帮助
