按鈕在TableRow中沒有正確顯示

Question

我以編程方式在TableRow中添加Button。當我添加按鈕時，按鈕顯示在我想要的位置，除了它看起來像按鈕被向下移動。我想讓按鈕居中對齊。這裏是我正在添加的按鈕，錶行，我的錶行的XML，和什麼我的按鈕看起來什麼，當我跑我的應用程序如圖片

public void addNewButtonToRegister(String buttonString, String buttonPrice, Button_Sizes buttonSize){ 
    Button newButton = new Button(getActivity().getApplicationContext()); 
    Button addButton = (Button) mMenuFragment.findViewById(R.id.add_button); 
    int height = addButton.getHeight(); 
    int width = addButton.getWidth(); 
    newButton.setLayoutParams(new TableRow.LayoutParams(height, width)); 
    newButton.setText(buttonString + "\n" + buttonPrice); 
    TableRow firstRow = (TableRow) mMenuFragment.findViewById(R.id.first_row); 
    firstRow.addView(newButton); 
} 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
      android:orientation="vertical" 
      android:padding="@dimen/activity_vertical_margin" 
      android:layout_width="match_parent" 
      android:id="@+id/test" 
      android:layout_height="match_parent"> 

<TableLayout 
    android:id="@+id/table_layout" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"> 

    <TableRow 
     android:orientation="horizontal" 
     android:id="@+id/first_row"> 

     <Button 
      android:id="@+id/add_button" 
      android:text="@string/add_button" 
      android:textSize="30dp" 
      android:layout_width="@dimen/register_button_size" 
      android:layout_height="@dimen/register_button_size"/> 



    </TableRow> 

</TableLayout>

試試這個代碼，我根據重量的概念設計，並根據您的意願修改它

<?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"

    <TextView

    <TableLayout 
     android:id="@+id/tableLayout1" 
     android:layout_width="match_parent"

     </TableRow>
