Question

我想创建一个表格，其中的列文字取决于微调器。稍后添加行，我可以为指定的单元格着色。它看起来像这样：http://tinypic.com/view.php?pic=2j639xf&s=8#.U-mRRpD-Lcs 这个例子是风景，因为我在dekstop上开发它，所以我想要一个像android那样的表格。

问题是： 1.当我在设备上运行它时，旋转器就消失了我还不知道如何为表格中的每个单元格着色。或者我应该提出一个新问题？

这是我的代码：

@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;
}

对于函数createTableLayout（row，column，rl，cl）;我使用http://www.prandroid.com/2014/05/creating-table-layout-dynamically-in.html

中的代码

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上的新手，我使用的是eclipse。这是我的第一篇帖子，请原谅我的英语。任何建议都表示赞赏，谢谢。

几点：

如果我理解正确的话，

你需要＆＃34;添加＆＃34;滚动视图到根视图linearlayout。
为Spinner添加自定义项目选定侦听器，并根据选择更改布局

e.g

示例代码：

@覆盖 protected void onCreate（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)

public class 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) {
      }

    }

使用列创建表格布局取决于Android中的微调器
