動態添加EditText到非兒童佈局的另一個LinearLayout

Question

我想在屏幕上有兩個佈局。一個可滾動的，另一個應該包含一個按鈕，可以添加可滾動佈局的東西，並始終應該可見。我不確定我是否正朝着正確的方向前進，但到目前爲止，我已經擁有了這個功能，而且我的代碼工作方式並不令人期待。如果單擊buttonSPAddText EditText與按鈕出現在同一行中。我希望它在另一個版式linearLayoutSPTextHolder之下出現在它們下面。

這是我的XAML：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:p1="http://schemas.android.com/apk/res/android" 
    p1:orientation="vertical" 
    p1:minWidth="25px" 
    p1:minHeight="25px" 
    p1:layout_width="match_parent" 
    p1:layout_height="match_parent" 
    p1:id="@+id/linearLayoutSPMain"> 
    <LinearLayout 
     p1:orientation="horizontal" 
     p1:minWidth="25px" 
     p1:minHeight="25px" 
     p1:layout_width="match_parent" 
     p1:layout_height="51.0dp" 
     p1:id="@+id/linearLayoutSPButtonHolder" 
     p1:layout_weight="1"> 
     <Button 
      p1:text="AddText" 
      p1:layout_width="wrap_content" 
      p1:layout_height="match_parent" 
      p1:id="@+id/buttonSPAddText" 
      p1:layout_weight="1" /> 
     <Button 
      p1:text="Do nothing" 
      p1:layout_width="wrap_content" 
      p1:layout_height="match_parent" 
      p1:id="@+id/buttonSPDoNth" 
      p1:gravity="center_vertical" 
      p1:layout_weight="1" /> 
    </LinearLayout> 
    <ScrollView 
     p1:minWidth="25px" 
     p1:minHeight="25px" 
     p1:layout_width="match_parent" 
     p1:layout_height="wrap_content" 
     p1:id="@+id/scrollViewSPText" 
     p1:layout_weight="6"> 
     <LinearLayout 
      p1:orientation="vertical" 
      p1:minWidth="25px" 
      p1:minHeight="25px" 
      p1:layout_width="match_parent" 
      p1:layout_height="wrap_content" 
      p1:id="@+id/linearLayoutSPTextHolder" 
      p1:scrollbars="horizontal" /> 
    </ScrollView> 
</LinearLayout> 

和我的活動：

namespace TiesaDrasaAndroid 
{ 
[Activity (Label = "SelectPlayersActivity")]    
public class SelectPlayersActivity : Activity 
{ 
    private int _textBoxId = 1000; 
    private LinearLayout _layout = null; 

    protected override void OnCreate (Bundle bundle) 
    { 
     base.OnCreate (bundle); 
     SetContentView (Resource.Layout.SelectPlayers); 

     _layout = (LinearLayout)FindViewById(Resource.Id.linearLayoutSPTextHolder); 
     _layout.Orientation = Orientation.Vertical; 
     Button addPl = FindViewById<Button>(Resource.Id.buttonSPAddText); 

     addPl.Click += delegate { 
         this.CreateUserTextBox(); 
     }; 
    } 
    private void CreateUserTextBox() 
    { 
     var textbox = new EditText (this); 
     textbox.Id = _textBoxId; 
     textbox.SetWidth (100); 
     _textBoxId++; 
     _layout.AddView (textbox); 

    } 
}

此代碼爲我工作得非常好：

public class MainActivity extends Activity { 
    private int _textBoxId = 1000; 
    private LinearLayout _layout = null; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     _layout = (LinearLayout) findViewById(R.id.linearLayoutSPTextHolder); 
//  _layout.setOrientation(LinearLayout.VERTICAL); 
     Button addPl = (Button) findViewById(R.id.buttonSPAddText); 

     addPl.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       CreateUserTextBox(); 
      } 
     }); 
    } 

    private void CreateUserTextBox() { 
     LayoutParams lpView = new LayoutParams(LayoutParams.WRAP_CONTENT, 
       LayoutParams.WRAP_CONTENT); 
     EditText textbox = new EditText(this); 
     textbox.setId(_textBoxId); 
     textbox.setText(_textBoxId + ""); 
     textbox.setLayoutParams(lpView); 
     _textBoxId++; 
     _layout.addView(textbox); 

    } 
}
