TableLayout中的相同寬度的列，*編程*

Question

我讀過SO，爲了獲得每個列具有相同寬度的表格佈局，您可以將android:width="0dp"和android:weight="1"設置爲佈局參數，並且它可以工作。 我會得到相同的結果，但是編程，所以我想這大塊的代碼：

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View rootView = inflater.inflate(R.layout.fragment_score, container, false); 

    TableRow row = (TableRow)rootView.findViewById(R.id.playerRow); 
    for (Player p : game.getPlayers()) { 
     TextView t = new TextView(rootView.getContext()); 
     t.setText(p.getName()); 
     row.addView(t, new TableLayout.LayoutParams(0, TableLayout.LayoutParams.WRAP_CONTENT, 1f)); 
     // with the previuos line of code, nothing is showed 
     // instead this work: row.addView(t) , but each column doesn't take the maximum width (as I would) 

    } 

    return rootView; 
} 

但在評論的解釋，預期這是行不通的。 我無法得到我想念的東西。

Answer 1

有一個在我的代碼中的錯誤，是的LayoutParams錯課，我應該用TableRow.LayoutParams代替TableLayout.LayoutParams，所以：

row.addView(t, new TableRow.LayoutParams(0, TableRow.LayoutParams.WRAP_CONTENT, 1f)); 

按預期工作。

你可以嘗試這樣。

    <!-- 2 columns --> 
    <TableRow
