活动泄漏了最初添加的窗口

这个错误是什么，为什么会发生?

通常这个问题是由于进度对话框发生的:你可以在你的活动中使用以下任何一种方法来解决这个问题:

 // 1):
          @Override
                protected void onPause() {
                    super.onPause();
                    if ( yourProgressDialog!=null && yourProgressDialog.isShowing() )
                  {
                        yourProgressDialog.cancel();
                    }
                }

       // 2) :
         @Override
            protected void onDestroy() {
                super.onDestroy();
                if ( yourProgressDialog!=null && yourProgressDialog.isShowing()
               {
                    yourProgressDialog.cancel();
                }
            }

你可以通过一个简单的/愚蠢的错误得到这个异常，通过(例如)在显示AlertDialog后不小心调用finish()，如果你错过了switch语句中的break call语句……

   @Override
   public void onClick(View v) {
    switch (v.getId()) {
        case R.id.new_button:
            openMyAlertDialog();
            break; <-- If you forget this the finish() method below 
                       will be called while the dialog is showing!
        case R.id.exit_button:
            finish();
            break;
        }
    }

finish()方法将关闭Activity，但AlertDialog仍然显示!

因此，当您专注地盯着代码，寻找糟糕的线程问题或复杂的编码等时，不要只见树不见林。有时它可能只是一些简单而愚蠢的事情，如缺少break语句。：）

也许你在activity中使用了findViewById而不是dialog。findViewById，然后在空实例上设置OnClickListener，这可能会导致原始错误。

我在AlertDialog上错误地调用hide()而不是dismiss()触发了这个错误。

有问题，当一个ProgressDialog仍然显示时，我完成了一个活动。

所以首先隐藏对话框，然后完成活动。

这就是我如何解决这个bottomSheetDialog.dismiss()在活动的finesh()之前的对话框

  startActivity(Intent(this, Activity::class.java))
        bottomSheetDialog.dismiss()
        finish()
