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();
    }
}

其他回答

解决方案是在退出Activity之前在view .java:183中创建的对话框上调用dismiss()，例如在onPause()中。所有的窗口和对话框应该在离开一个活动之前关闭。

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)。

尝试下面的代码，它将在任何时候工作，你将解散进度对话框，它将看到它的实例是否可用。

try {
        if (null != progressDialog && progressDialog.isShowing()) {
            progressDialog.dismiss();
            progressDialog = null;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

确保打电话 this.dialog.show。(活动)

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。：）
