向上滑動底部工作表查看屏幕頂部

Question

我想實現底部工作表行為：peek 在 STATE_EXPANDED 處滑出屏幕頂部，如圖所示。 我怎樣才能做到這一點？

您可以在聆聽BottomSheetBehavior嘗試對 BottomSheet 布局進行一些更改：

BottomSheetBehavior behavior = BottomSheetBehavior.from(mBottomSheetBehavior);  
behavior.setBottomSheetCallback(new BottomSheetCallback() {  
   @Override  
   public void onStateChanged(@NonNull View bottomSheet, int newState) {  
    // Here you can implement your logic with layour change
   }  

  @Override  
  public void onSlide(@NonNull View bottomSheet, float slideOffset) {  
     // Here you can implement your logic with layour change
  }  
});
