在一个活动中动态分配两个布局的问题

我正在尝试处理需要在同一活动布局中的两个水平滚动视图中分配两个 LinearLayout 或 TableRow 的逻辑，但它似乎不起作用。任何帮助将不胜感激

这是活动的代码：

public class ViewTestActivity extends Activity implements OnClickListener {
    /** Called when the activity is first created. */
    LinearLayout LinearLayoutInScrollView;
    LinearLayout Inner1HorizontalLinearLayout;
    LinearLayout Inner2HorizontalLinearLayout;
    ScrollView ScrollViewMain;
    HorizontalScrollView horizontalScrollViewOfMain;
    TextView textViewOne;
    TextView textViewTwo;
    Button verticalScrollTriggerButton;
    Button horizontalScrollTriggerButton;

    @Override    

public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            LinearLayoutInScrollView = (LinearLayout) findViewById(R.id.MainscrollViewLayout);

            horizontalScrollViewOfMain = new HorizontalScrollView(this);
            LinearLayoutInScrollView.addView(horizontalScrollViewOfMain);



            verticalScrollTriggerButton = new Button(this);
            verticalScrollTriggerButton.setText("CheckVerticalScroll");
            verticalScrollTriggerButton.setOnClickListener(new OnClickListener() {

                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    for (int i = 0; i < 30; i++) {
                        textViewOne = new TextView(getApplicationContext());
                        textViewOne.setBackgroundColor(0xaa000000);
                        textViewOne.setText("This is Dynamic");
                        LinearLayoutInScrollView.addView(textViewOne);
                    }

                }
            });

            horizontalScrollTriggerButton = new Button(this);
            horizontalScrollTriggerButton.setText("CheckHorizontalScroll");
            horizontalScrollTriggerButton.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Inner1HorizontalLinearLayout = new LinearLayout(getApplicationContext());
                    Inner2HorizontalLinearLayout = new LinearLayout(getApplicationContext());               
                    for (int i = 0; i < 30; i++) {
                        textViewOne = new TextView(getApplicationContext());
                        textViewOne.setBackgroundColor(0xaa000000);
                        textViewOne.setText("This is Dynamic textViewOne");
                        Inner1HorizontalLinearLayout.addView(textViewOne);
                        textViewTwo = new TextView(getApplicationContext());
                        textViewTwo.setBackgroundColor(0xaa000000);
                        textViewTwo.setText("This is Dynamic textViewTwo");
                        Inner2HorizontalLinearLayout.addView(textViewTwo);                  
                    }
                    horizontalScrollViewOfMain.addView(Inner1HorizontalLinearLayout);
                    horizontalScrollViewOfMain.addView(Inner2HorizontalLinearLayout);
                }

            });

            LinearLayoutInScrollView.addView(verticalScrollTriggerButton);
            LinearLayoutInScrollView.addView(horizontalScrollTriggerButton);

        }

这是 main.xml 的代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ScrollView
        android:id="@+id/MainscrollView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <LinearLayout
            android:id="@+id/MainscrollViewLayout"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="vertical" >


        </LinearLayout>

    </ScrollView>

</LinearLayout>

那么我看到的第一个问题是这两行：

horizontalScrollViewOfMain.addView(Inner1HorizontalLinearLayout);
horizontalScrollViewOfMain.addView(Inner2HorizontalLinearLayout);

任何 scrollView 都是框架视图，并且只能有一个内部视图。

我现在不在计算机上运行代码/查看更多细节，并且您没有详细说明您遇到的确切问题。但看看这是否解决了你的问题。
