线30：BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from（查看）parentView.getParent（）;

Answer 1

也许你需要通过parentView在BottomSheetBehaviour.from()这样

public class Events extends AppCompatActivity{ 

    Button button; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.events); 

     button = (Button)findViewById(R.id.event); 

     button.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       BottomSheetDialog bottomSheerDialog = new BottomSheetDialog(Events.this); 
       View parentView = getLayoutInflater().inflate(R.layout.dialog,null); 
       bottomSheerDialog.setContentView(parentView); 
       BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(parentView.getParent()); 
       bottomSheetBehavior.setPeekHeight(int); TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,200,getResources().getDisplayMetrics()); 
       bottomSheerDialog.show(); 
      } 
     }); 


    } 

}
