Question

好吧，我在我的智慧结束。
我在做什么：
- 获取xml
- 解析xml
- 根据解析的xml加载布局（EditText框）（通过带有kay / value东西的包装类）
- 在onSaveInstanceState中保存xml - 在onSaveInstanceState中保存EditText框内容（获取键/值对） - - ＆gt; 手动旋转屏幕
- 加载xml并再次解析它 - 根据新生成的EditText框的键

获取EditText框的键/值对

我想做什么：
- 使用旧内容（取决于键）设置新EditText框的文本

问题
- 未设置文字

代码

BaseCommentComponent

public abstract class BaseCommentComponent {

    protected LinearLayout currentLinearLayout;
    protected Context context;
    protected Request request;
    private Button sendButton;
    protected Button abortButton;
    private final EditText textField;
    private final EditText nameTextField;
    private Comment comment;

    public BaseCommentComponent(LinearLayout currentLinearLayout, Comment comment, Context context, Request request, Button sendButton, Button abortButton, EditText textField,
            EditText nameTextField) {
        this.currentLinearLayout = currentLinearLayout;
        this.comment = comment;
        this.context = context;
        this.request = request;

    }

    private OnClickListener getInitialButtonListener() {
        System.out.println("getInitialButtonListener");
        OnClickListener replyButtonClickedListener = new OnClickListener() {

            @Override

        sendButton.setText("Send");
    }

    private OnClickListener getAbortButtonListener(final Button replyButton, final Button replyButtonAbort, final EditText replyTextField, final EditText replyNameTextField) {

        OnClickListener abortListener = new OnClickListener() {

    }

        System.out.println("restoreOriginalCommentComponentState");
        sendButton.setText(getOriginalButtonText());
        OnClickListener initialReplyButtonListener = getInitialButtonListener();

        return comment;
    }

    protected abstract String getOriginalButtonText();

    protected abstract String getMessageToBeDisplayedOnSuccessfulSending();

    public LinearLayout getLinearLayout() {

    public void setText(final String text) {

    public EditText getTextField() {
        return textField;
    }

    public EditText getNameTextField() {
        return nameTextField;
    }
}

CommentCreationComponent

public class CommentCreationComponent extends BaseCommentComponent {

    public CommentCreationComponent(LinearLayout currentLinearLayout, Comment comment, Context context, Request request, Button sendButton,
            Button abortButton, EditText textField, EditText nameTextField) {
        super(currentLinearLayout, comment, context, request, sendButton, abortButton, textField, nameTextField);
        sendButton.setVisibility(Button.VISIBLE);
        sendButton.setText(getOriginalButtonText());
    }

    @Override
    protected String getOriginalButtonText() {
        return "New comment";
    }

    @Override
    protected String getPartialUrl() {
        return "publication/addComment";
    }

    @Override
    protected String getMessageToBeDisplayedOnSuccessfulSending() {
        return "Comment was sent";
    }

}

CommentSectionComponent

public class CommentSectionComponent {

    private LinearLayout placeHolder;
    private List<BaseCommentComponent> baseCommentComponents = new ArrayList<BaseCommentComponent>();

    public CommentSectionComponent(Context context) {
        Activity activity = (Activity) context;
        placeHolder = (LinearLayout) activity.findViewById(R.id.placeHolder);
        TextView commentSectionHeader = new TextView(context);
        commentSectionHeader.setText("Kommentare");
        ComponentHelper.convertToHeaderLabel(commentSectionHeader, context);
        ComponentHelper.setPublicationDetailLayout(placeHolder);
        placeHolder.addView(commentSectionHeader);
    }

    public void addCommentComponent(BaseCommentComponent comment) {
        baseCommentComponents.add(comment);
        LinearLayout linearLayout = comment.getLinearLayout();
        placeHolder.addView(linearLayout);
    }

    public List<BaseCommentComponent> getBaseCommentComponents() {
        return baseCommentComponents;
    }
}

奇怪的是，我可以做这样的事情：
（在BaseCommentComponent中）

private OnClickListener getInitialButtonListener() {
            System.out.println("getInitialButtonListener");
            OnClickListener replyButtonClickedListener = new OnClickListener() {

                @Override
                public void onClick(View v) {

                    openCommentForWriting();
                    sendButton.setOnClickListener(getSendButtonClickedListener());
                    textField.setText("yep");
                }

            };
            return replyButtonClickedListener;
        }

当我手动点击按钮时它会起作用，但是当我将按钮输入我的Activity（只是将其传递出去）并以编程方式点击它时，它不起作用。
正如你所看到的，我已经尝试了一些无用的东西。我还检查了对象ID并且它们匹配（只是为了排除意外覆盖某处的组件）
我也已经尝试删除所有可见性 - 从一开始就显示EditText-Fields，显然没有解决我的问题。

有人为挑战而奋斗吗？（非常感谢任何帮助）
