我的 Android 应用程序有一些奇怪的问题。我正在创建AlertDialog两个EditText控件和一些按钮（编辑现有对象）。

@Override
public void onClick(View arg0) {
    AlertDialog.Builder alert = new AlertDialog.Builder(mContext);

    final View dialogLayout = mInflater.inflate(R.layout.event_edit, null);
    alert.setView(dialogLayout);

    ((EditText)dialogLayout.findViewById(R.id.txtCompany)).setText(cEvent.getCompany());
    ((EditText)dialogLayout.findViewById(R.id.txtCity)).setText(cEvent.getCity());

    alert.setTitle(R.string.DialogEditEventTitle);
    alert.setPositiveButton(R.string.DialogEditEventDelete,
            new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            // Delete action
        }
    });

    alert.setNeutralButton(R.string.DialogEditEventSave,
            new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            // Save
        }
    });

    alert.setNegativeButton(R.string.DialogEditEventCancel,
            new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            // Cancel action
        }
    });
    AlertDialog dialog = alert.show();
    dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

}

如果我尝试改变焦点或放置一些东西来编辑文本字段，那么我会得到异常：

此异常的原因是什么，我该如何解决？

Please try; 

//first create, set soft input mode and then show//

AlertDialog dialog = alert.create();     
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
dialog.show();
