因此，每当我按下fab时，背景线性布局的附加活动也会打开。那么有谁能告诉我代码有什么问题？即使把FAB按钮放在线性布局之外，我也不知道为什么会出现这个问题。

Java代码： -

fab=(FloatingActionButton) findViewById(R.id.fab_add_reminders);

        fab.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {

                //Set reminder dialog box appear
                openDialogToAddReminder();
                return false;
            }
        });


nightLL.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Constants.SelectedBucket="Night";
                startActivity(new Intent(Reminders.this, ListReminders.class));
            }
        });

您在OnTouchListener而不是FloatingActionButton上使用OnClickListener，而您在OnTouchListener内也返回false，这意味着fab不会消耗触摸事件并将其传递到下面的下一个视图（nightLL）。

将您的代码更改为：

fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            openDialogToAddReminder();
        }
    });

或者，如果您出于任何其他原因想要使用OnTouchListener，请使用此代码：

fab.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    Toast.makeText(FabClickActivity.this, "FAB Touch.", Toast.LENGTH_SHORT).show();
                }
                return true;
            }
        });

按下浮动操作按钮后，活动也会启动
