java.lang.IllegalArgumentException - dialog.dismiss

Question

我在已发布的应用程序中收到此错误，只有客户端会收到此错误。我已经尝试过多次复制同样的错误，但都没有成功。 我也已经尝试在所有有对话框但也没有解决的位置使用下面的代码。

if (dialog.isShowing ()) {
    dialog.dismiss ();
}

Answer 1

我可以看到您正试图在 AsyncTask 的 postExecute 上关闭 ProgressDialog。这本身是一种很好的做法，但有时会出现问题，我之前也经历过这种情况，尤其是在您显示 ProgressDialog 并突然旋转视图时。

我找到的解决方案如下：

您将需要这些函数来处理正确的解雇并避免崩溃。

private void dismissProgressDialog(ProgressDialog progressDialog) {
            if (progressDialog != null) {
                if (progressDialog.isShowing()) {

                    //get the Context object that was used to create the dialog
                    Context context = ((ContextWrapper) progressDialog.getContext()).getBaseContext();

                    // if the Context used here was an activity AND it hasn't been finished or destroyed
                    // then dismiss it
                    if (context instanceof Activity) {

                        // Api >=17
                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                            if (!((Activity) context).isFinishing() && !((Activity) context).isDestroyed()) {
                                dismissWithExceptionHandling(progressDialog);
                            }
                        } else {

                            // Api < 17. Unfortunately cannot check for isDestroyed()
                            if (!((Activity) context).isFinishing()) {
                                dismissWithExceptionHandling(progressDialog);
                            }
                        }
                    } else
                        // if the Context used wasn't an Activity, then dismiss it too
                        dismissWithExceptionHandling(progressDialog);
                }
                progressDialog = null;
            }
        }


public void dismissWithExceptionHandling(ProgressDialog dialog) {
            try {
                dialog.dismiss();
            } catch (final IllegalArgumentException e) {
                // Do nothing.
            } catch (final Exception e) {
                // Do nothing.
            } finally {
                dialog = null;
            }
        }

在您的 AsyncTask 的 onPostExecute 上实现该功能。

@Override
 protected void onPostExecute(Boolean b) {
     // pass in the progressDialog as a parameter to the method
     dismissProgressDialog(progressDialog);
 }

Answer 2

在你的活动中写下这段代码

onStop()

方法。当任何人按下主页按钮并且打开对话框时，就会出现此错误。因为点击主页按钮时 onPause() 和 onStop() 方法调用。希望这会有所帮助。

 if (dialog!=null && dialog.isShowing ()) {
          dialog.dismiss ();
             }

Answer 3

修改此代码：View not attached to window manager crash 如何重现该错误：

private static void dismissDialog(Activity activity, Dialog dialog) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        if (activity.isDestroyed()) { // or call isFinishing() if min sdk version < 17
            return;
        }
    } else {
        if (activity.isFinishing()) { // or call isFinishing() if min sdk version < 17
            return;
        }
    }
    if (null != dialog && dialog.isShowing()) {
        dialog.dismiss();
    }
}

Answer 4

您正在对当前不再显示的对话框调用解除。如：当你调用dismiss时，你的Activity/Fragment可能已经被销毁了。
