当前回答

当activity销毁时解散对话框

@Override
protected void onDestroy()
{
    super.onDestroy();
    if (pDialog!=null && pDialog.isShowing()){
        pDialog.dismiss();
    }
}

其他隐藏你的对话框,将其解散。

用.dismiss()替换.hide()

我最近也遇到了同样的问题。

这个问题背后的原因是在对话框被解散之前活动被关闭了。 上述情况的发生有多种原因。上面的帖子中提到的也是正确的。

我陷入了一种情况,因为在线程中,我调用了一个抛出异常的函数。因此,窗口被关闭,因此出现异常。

当试图从后台线程显示吐司时得到此错误。 这是通过在UI线程上运行UI相关代码来解决的

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。:)

当您尝试在活动有效完成后显示警报时,会出现“活动已泄漏最初添加的窗口…”错误。

AFAIK,你有两个选择:

重新考虑登录alert:在实际退出activity之前调用对话框上的dismiss()。 将对话框放在不同的线程中,并在该线程上运行它(与当前活动无关)。
