Java 如何在Android中动态地拥有一个带有可滚动内容的固定标题？

我以编程方式创建了一个包含按钮的

RelativeLayout

。我还创建了一个

滚动视图

，其中包含一个

线性布局

，其中有10多个

文本视图

。我希望将

相对长度调整为顶部对齐并固定。当有人试图向下滚动时，我希望所有的
文本视图都位于固定的
相对视图之后。我希望那个按钮始终可见。使用此代码时，将不显示
RelativeLayout
和按钮。我哪里错了？


相对长度（固定）

-按钮

线性布局

-滚动视图

-文本视图

-+其他10个文本视图

这是我的密码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    final RelativeLayout relativeLayout = new RelativeLayout(this);
    RelativeLayout.LayoutParams relativeLayoutParams = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    relativeLayout.setLayoutParams(relativeLayoutParams);
    this.setContentView(relativeLayout);

    final Button restartButton = new Button(this);
    restartButton.setText(R.string.restartButton);
    LinearLayout.LayoutParams buttonParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    restartButton.setLayoutParams(buttonParams);
    relativeLayout.addView(restartButton);

    ScrollView scrollView = new ScrollView(this);
    this.setContentView(scrollView);

    final LinearLayout linearLayout = new LinearLayout(this);
    LinearLayout.LayoutParams linearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    linearLayout.setLayoutParams(linearLayoutParams);
    linearLayout.setOrientation(linearLayout.VERTICAL);
    scrollView.addView(linearLayout);

    TextView textView1 = new TextView(this);
    testTitle.setText(R.string.text_view1);
    linearLayout.addView(textView1);

    // + other 10 text views
}

谢谢
 在代码中，用ScrollView替换RelativeLayout。只需先将一些线性布局设置为contentView，然后通过
addView（RelativeLayout）
将您的RelativeLayout放在那里，并通过
addView（scrollView）

编辑：

您的新代码：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        final LinearLayout mainLinearLayout = new LinearLayout(this);
        LinearLayout.LayoutParams mainLinearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
        mainLinearLayout.setLayoutParams(mainLinearLayoutParams);
        mainLinearLayout.setOrientation(LinearLayout.VERTICAL);
        this.setContentView(mainLinearLayout);

        final RelativeLayout relativeLayout = new RelativeLayout(this);
        RelativeLayout.LayoutParams relativeLayoutParams = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        relativeLayout.setLayoutParams(relativeLayoutParams);
        mainLinearLayout.addView(relativeLayout);

        final Button restartButton = new Button(this);
        restartButton.setText(R.string.restartButton);
        LinearLayout.LayoutParams buttonParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        restartButton.setLayoutParams(buttonParams);
        relativeLayout.addView(restartButton);

        ScrollView scrollView = new ScrollView(this);
        mainLinearLayout.addView(scrollView);

        final LinearLayout linearLayout = new LinearLayout(this);
        LinearLayout.LayoutParams linearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        linearLayout.setLayoutParams(linearLayoutParams);
        linearLayout.setOrientation(linearLayout.VERTICAL);
        scrollView.addView(linearLayout);

        TextView textView1 = new TextView(this);
        testTitle.setText(R.string.text_view1);
        linearLayout.addView(textView1);

        // + other 10 text views
    }

编辑2：将第一个linearLayout重命名为mainLinearLayout根据有关代码的注释
，我将第一个
linearLayout
重命名为
mainLinearLayout
，因为有两个布局同名。最后，它工作得很好。非常感谢你！
