第30行：BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from（View）parentView.getParent（）;

Answer 1

也许您需要像这样在BottomSheetBehaviour.from()传递parentView

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();
            }
        });


    }

}
