enter image description here我該如何放置我的按鈕?

我想把這樣的數字按鈕。這是我的代碼:

LinearLayout layout = new LinearLayout(this); 
     layout.setOrientation(LinearLayout.VERTICAL); 

     LinearLayout layout2 = new LinearLayout(this); 
     layout2.setOrientation(LinearLayout.HORIZONTAL); 

     TextView titleView = new TextView(this); 
     titleView.setText("Hello World!"); 
     layout.addView(titleView); 

     android.widget.LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
       LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT, 1); 
     android.widget.TableLayout.LayoutParams params = new TableLayout.LayoutParams(
       LayoutParams.MATCH_PARENT, LayoutParams.FILL_PARENT, 1); 

     Button btnConnect = new Button(this); 
     btnConnect.setText("Connect"); 
     btnConnect.setLayoutParams(param); 
     layout2.addView(btnConnect); 

     Button btnDisconnect = new Button(this); 
     btnDisconnect.setText("Disconnect"); 
     layout2.addView(btnDisconnect); 
     btnDisconnect.setLayoutParams(param); 


     layout.addView(layout2); 

     TableLayout tblLayout = new TableLayout(this); 
     tblLayout.setOrientation(TableLayout.HORIZONTAL); 
     TableRow tblrow = null; 



     for (int i = 1; i <= 9; i++) { 
      if (i % 3 == 1) { 
       tblrow = new TableRow(this); 
       tblLayout.addView(tblrow); 

      } 

      Button b = new Button(this); 
      b.setText("" + i); 
      tblrow.addView(b); 
     } 




     TableRow tr = new TableRow(this); 
     Button btnZero = new Button(this); 
     btnZero.setText("0"); 
     Button btnHash = new Button(this); 
     btnHash.setText("#"); 
     Button btnStar = new Button(this); 
     btnStar.setText("*"); 
     tr.addView(btnZero); 
     tr.addView(btnHash); 
     tr.addView(btnStar); 
     tblLayout.addView(tr); 




     layout.addView(tblLayout); 
     setContentView(layout); 

這符合以下標準:

爲了使我的專欄這樣。我用這個代碼:

android.widget.TableLayout.LayoutParams params = new TableLayout.LayoutParams(
       LayoutParams.MATCH_PARENT, LayoutParams.FILL_PARENT, 1); 
tblLayout.setLayoutParams(param); 

但沒有變化。我需要做什麼?這是Layoutparams不足以做到這一點?

您可以在佈局中放置佈局。例如,你可以用「LinearLayout」水平放置頂部按鈕,其餘部分用「GridLayout」放置。 – 2013-03-05 22:17:53

是的,你是對的我需要使用TableLayout。這是必須的 – snnlaynnkrdsm 2013-03-05 22:18:45

是否有你不在XML文件中這樣做的原因?看起來像矯枉過正,在代碼中動態創建它。 – dymmeh 2013-03-05 22:29:33

你需要設置的layoutlayout2tblLayout,每個tblRow,並且trMATCH_PARENT寬度和每個按鈕必須有平等的layout_weight

LayoutParams.FILL_PARENT,1最後1是寬度不是它,但不工作 – snnlaynnkrdsm 2013-03-05 22:23:19
