android - 即使我在Android上调用onCreateDialog，也不会创建AlertDialog

我面临以下问题。
我有一个图像Gallery并且我想打开一个AlertDialog来显示有关单击图像的一些信息。我第一次点击图片时，它运行得很好。但是在接下来的时间里，即使我点击了一个不同的图片，同样的对话框再次出现。
用户名
当我关注这个用户案例时
在位置2中选择图像
关闭对话框
选择位置6中的图像
关闭对话框
，我得到这些指纹：

click na galeria... position: 2
startUserInformationDialog()... `this.position`: 2
onCreateDialog on switch.. `this.position`: 2
DISMISSING DIALOG `this.position`: 2

click na galeria... position: 6
startUserInformationDialog()... `this.position`: 6
DISMISSING DIALOG `this.position`: 6

这意味着代码没有通过oncreatedialog运行
代码

public AlertDialog createUserInformationAlertDialog() {
        LayoutInflater inflater = getLayoutInflater();
        View dialoglayout = inflater.inflate(R.layout.dialog_user_info,
                (ViewGroup) findViewById(R.id.dialog_user_layout_root));
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setView(dialoglayout);
        final MyObject ea = myList.get(positionUserToHaveInformationDisplayedOnTheDialog);
            // Setting values according to element to be shown
            TextView textView = (TextView) dialoglayout
                    .findViewById(R.id.user_name_value);
            textView.setText(ea.getName());
            ...
            builder.setNegativeButton(Locale_PT_BR.BACK,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,
                                int whichButton) {
                            Log.d("PRINT 1",
                                    "DISMISSING DIALOG `this.position`: "
                                            + positionUserToHaveInformationDisplayedOnTheDialog);
                            dialog.dismiss();
                        }
                    });
            return builder.create();
}


private void startUserInformationDialog() {
    Log.d("PRINT 2", "startUserInformationDialog()... `this.position`: "
            + positionUserToHaveInformationDisplayedOnTheDialog);
    showDialog(DIALOG_USER_INFORMATION);
}



@Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DIALOG_USER_INFORMATION:
            Log.d("PRINT 3", "onCreateDialog on switch.. `this.position`: "
                    + positionUserToHaveInformationDisplayedOnTheDialog);
            return createUserInformationAlertDialog();
        default:
            return null;
        }
    }

private void startGallery() {
        myPhotoBar = (Gallery) findViewById(R.id.gallery);
        myPhotoBar.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView parent, View v, int position,
                    long id) {
                Log.d("PRINT 4", "click na galeria... position: " + position);
                positionUserToHaveInformationDisplayedOnTheDialog = position;
                startUserInformationDialog();
            }
        });

}

最佳答案

使用onPrepareDialog()方法用数据填充对话框。如果要销毁对话框，应该调用removeDialog()方法。
