任何人都可以帮忙告诉我这次崩溃的原因以及如何解决？

修改

这是显示对话框的方法

public static void showDialogMessage(Activity activity, String title,
            String message, String buttonString, final OnClickListener listener) {

        try {
                final Dialog dialog = new Dialog(activity);
                dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
                dialog.setContentView(R.layout.dialog_error_message_layout);
                dialog.setCancelable(false);

                TextView titleTV = (TextView) dialog.findViewById(R.id.title_textview);
                TextView descriptionTV = (TextView) dialog
                        .findViewById(R.id.description_textview);
                Button okButton = (Button) dialog.findViewById(R.id.ok_button);
                Button cancelButton = (Button) dialog.findViewById(R.id.cancel_button);

                titleTV.setText(title);
                descriptionTV.setText(message);
                okButton.setText(buttonString);
                cancelButton.setVisibility(View.GONE);

                okButton.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        dialog.dismiss();
                        if (listener != null)
                            listener.onClick(null);
                    }
                });

                dialog.getWindow().setBackgroundDrawableResource(
                        android.R.color.transparent);
                dialog.show();
        } catch (BadTokenException exception) {
            exception.printStackTrace();
        }
    }

在对话框成功解除之前Activity完成时会发生错误。因此，对话框的视图未附加到windowManager。

在解除对话框之前添加此检查：

if (!activity.this.isFinishing() && dialog != null) {
        dialog.dismiss();
    }

或者，您可以在活动的onPause()或onDestroy()中关闭对话框。

 @Override
public void onPause() {
    super.onPause();

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

在android中关闭对话框后崩溃
