如何在Android中將選項卡對齊中心？

我想將它對齊到屏幕中心。（水平和垂直）

該表是從java動態創建的。

我試過設置

TableLayout t1 = (TableLayout)findViewById(R.id.maintable); 
t1.setGravity(Gravity.CENTER);

但它只是從頂部對齊。

public class TabActivity extends Activity { 

Trny t = Trny.getInstance(); 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_tab); 

    TableLayout t1 = (TableLayout)findViewById(R.id.maintable); 
    t1.setGravity(Gravity.CENTER); 

     // first row of table 

     TableRow tr = new TableRow(this); 

     TextView place = new TextView(this); 
     poradi.setText("P" ); 
     poradi.setPadding(10, 5, 10, 5); 
     tr.addView(place); 

     TextView nameOfTeam = new TextView(this); 
     nazTymu.setText("Nazev" ); 
     nazTymu.setPadding(10, 5, 10, 5); 
     tr.addView(nameOfTeam); 

     TextView matchesPlayed = new TextView(this); 
     odehraneZapasy.setText("Z"); 
     odehraneZapasy.setPadding(10, 5, 10, 5); 
     tr.addView(matchesPlayed); 

     TextView numbefOfWins = new TextView(this); 
     pocetVyher.setText("V"); 
     pocetVyher.setPadding(10, 5, 10, 5); 
     tr.addView(numbefOfWins); 

     TextView numberOfTies = new TextView(this); 
     pocetRemiz.setText("R"); 
     pocetRemiz.setPadding(10, 5, 10, 5); 
     tr.addView(numberOfTies); 

     TextView numberOfLoses = new TextView(this); 
     pocetProher.setText("P"); 
     pocetProher.setPadding(10, 5, 10, 5); 
     tr.addView(numberOfLoses); 

     TextView goalsScored = new TextView(this); 
     skorePlus.setText("VG"); 
     skorePlus.setPadding(10, 5, 10, 5); 
     tr.addView(goalsScored); 

     TextView goalsGained = new TextView(this); 
     skoreMinus.setText("OG"); 
     skoreMinus.setPadding(10, 5, 10, 5); 
     tr.addView(goalsGained); 

     TextView numberOfPoints = new TextView(this); 
     pocBodu.setText("B"); 
     pocBodu.setPadding(10, 5, 10, 5); 
     tr.addView(numberOfPoints); 


     t1.addView(tr); 

       //more rows dynamically created from java 

} 

}

XML文件

  <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:id="@+id/maintable" > 
      </TableLayout>

我怎樣才能做到這一點？多謝你們。

這應該有固定的。嘗試設置CENTER_HORIZONTAL和CENTER_VERTICAL。你應該在佈局文件中給它，因爲你不需要動態轉換。 – pvn

佈局XML改變這種

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

     <TableLayout 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/maintable" 
     android:layout_centerInParent="true" > 
     </TableLayout> 
</RelativeLayout>
