当前回答

当我在AsyncTask中使用ProgressDialog时，这种情况发生在我身上。实际上，我在onPostExecute中使用hide()方法。基于@Alex Volovoy的答案，我需要使用遣散()与ProgressDialog删除它在onPostExecute和它完成。

progressDialog.hide(); // Don't use it, it gives error

progressDialog.dismiss(); // Use it

其他回答

这可能会有所帮助。

if (! isFinishing()) {

    dialog.show();

    }

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。：）

其他隐藏你的对话框，将其解散。

用.dismiss()替换.hide()

最好的解决方案是在try catch中添加对话框，并在异常发生时解散对话框

只需使用下面的代码

 try {
        dialog.show();
    } catch (Exception e) {
        dialog.dismiss();
    }

我正在使用一个视频播放器的对话框错误，而不是发疯(我已经测试了所有这些解决方案)

我选择了DialogFragment http://developer.android.com/reference/android/app/DialogFragment.html。

你可以在内部的DialogFragment类中返回构建器创建，只需要重写onCreateDialog
