创建带有列的表布局取决于Android中的旋转器

Question

我想创建一个表，列的文本取决于旋转器。稍后添加行，我可以为指定的单元格上色。它看起来像这样:http://tinypic.com/view.php?pic=2j639xf&s=8#.U-mRRpD-Lcs这个例子是横向的，因为我是在dekstop上开发的，所以我想要一个像那样的表格在android上的纵向。

问题是:1. 当我在设备上运行它时，旋转器消失了2. 我还不知道如何给表格中的每个单元格上色。还是我该提个新问题?

下面是我的代码:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_reservation_schedule);
    Spinner spinnerFacility = (Spinner)findViewById(R.id.spinnerFacility);
    ArrayList<String> alTop = getTimeTableColumnTop((int)spinnerFacility.getSelectedItemId());
    String[] column = alTop.toArray(new String[alTop.size()]);
    ArrayList<String> alLeft = getTimeTableColumnLeft();
    String[] row = alLeft.toArray(new String[alLeft.size()]);
      int rl=row.length+1; int cl=column.length+1;
       Log.d("--", "R-Lenght--"+rl+"   "+"C-Lenght--"+cl);
    ScrollView sv = new ScrollView(this);
       TableLayout tableLayout = createTableLayout(row, column,rl, cl);
       HorizontalScrollView hsv = new HorizontalScrollView(this);
       hsv.addView(tableLayout);
    sv.addView(hsv);
    setContentView(sv);
}
private ArrayList<String> getTimeTableColumnTop(int facilitySelectedIndex)
{
    ArrayList<String> timeTableColumnTop = new ArrayList<String>();
    if(facilitySelectedIndex == 0)
    {
        timeTableColumnTop.add("Discuss Room 1");
        timeTableColumnTop.add("Discuss Room 2");
        timeTableColumnTop.add("Discuss Room 3");
    }else
    {
        timeTableColumnTop.add("Pri-View 1");
        timeTableColumnTop.add("Pri-View 2");
        timeTableColumnTop.add("Pri-View 3");
        timeTableColumnTop.add("Pri-View 4");
        timeTableColumnTop.add("Pri-View 5");
    }
    return timeTableColumnTop;
}
private ArrayList<String> getTimeTableColumnLeft()
{
    ArrayList<String> timeTableColumnLeft = new ArrayList<String>();
    for(int i = 8 ; i<17; i++)
    {
        timeTableColumnLeft.add(i+":00");
    }
    return timeTableColumnLeft;
}

createTableLayout(row,column,rl,cl);我使用的代码来自http://www.prandroid.com/2014/05/creating-table-layout-dynamically-in.html

activity_reservation_schedule.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/reservation_spinner_facility_prompt"/>
<Spinner
    android:id="@+id/spinnerFacility"
    android:prompt="@string/reservation_spinner_facility_prompt"
    android:entries="@array/reservation_facility_entries"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />
</LinearLayout>

这里是strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">ReservationTab(Schedule)</string>
<string name="reservation_spinner_facility_prompt">Pick a facility</string>
<string-array name="reservation_facility_entries">
  <item>Discussion Room</item>
  <item>Private Viewing</item>
</string-array>
</resources>

注意:我是Android的新手，我正在使用eclipse。这是我在这里的第一个帖子，请原谅我的英语。

几点:

如果我没理解错的话，

你需要"添加"滚动视图到你的根视图linearlayout。
• 为旋转器添加自定义项目选定监听器并根据选择更改布局

如

示例代码:

@OverrideonCreate(Bundle savedInstanceState) {

    setContentView(R.layout.activity_main);
    ll = (LinearLayout)findViewById(R.id.ll);
    Spinner spinnerFacility = (Spinner)findViewById(R.id.spinnerFacility);
    spinnerFacility.setOnItemSelectedListener(new CustomOnItemSelectedListener());
    // more of your code.....
    ll.addView(sv)  // instead of setContentView(sv) 

公共类CustomOnItemSelectedListener实现OnItemSelectedListener {

      public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {
        Toast.makeText(parent.getContext(), 
            "OnItemSelectedListener : " + parent.getItemAtPosition(pos).toString(),
            Toast.LENGTH_SHORT).show();
        ll.removeView(sv);

        ArrayList<String> alTop = getTimeTableColumnTop(pos);
        String[] column = alTop.toArray(new String[alTop.size()]);
        ArrayList<String> alLeft = getTimeTableColumnLeft();
        String[] row = alLeft.toArray(new String[alLeft.size()]);
          int rl=row.length+1; int cl=column.length+1;
           Log.d("--", "R-Lenght--"+rl+"   "+"C-Lenght--"+cl);
         sv = new ScrollView(getApplicationContext());
           TableLayout tableLayout = createTableLayout(row, column,rl, cl);
           HorizontalScrollView hsv = new HorizontalScrollView(getApplicationContext());
           hsv.addView(tableLayout);
        sv.addView(hsv);
        ll.addView(sv);
      }
      @Override
      public void onNothingSelected(AdapterView<?> arg0) {
      }
    }
