如果每個行包含不同數量的視圖，如何在tablelayout中製作相同大小的視圖？

Question

我創建4個GIF圖像按鈕，並將它們加入到GIF圖像按鈕的列表：

for (int i = 0; i < 4; ++i) { 
    GifImageButton myButton = new GifImageButton(); 
    myButton.setBackgroundResource(drawables[i]); // add some drawable to the button background 
    myButton.setLayoutParams(new TableRow.LayoutParams(0, TableRow.LayoutParams.MATCH_PARENT, 1.0f)); 
    listButtons.add(myButton); 
} 

然後創建了一個tablelayout（行數= 2，列= 3）編程並將其添加到我的佈局：

MyTableLayout tableLayout = new MyTableLayout(this); 
tableLayout.createTableLayoutOfButtons(tableRows /*=2*/, tableCols /*=3*/, listButtons); 
mylinearLayout.addView(tableLayout); 

我MyTableLayout類：

public class MyTableLayout extends TableLayout { 

    public MyTableLayout(Context context) { 
     super(context); 
    } 

    // indexListButtons is the current index of the listButtons elements. so as long as there are buttons, we will add them to the table rows 
    int indexListButtons = 0; 
    public void createTableLayoutOfButtons(int numRows, int numCols, List<GifImageButton> listButtons) { 
     setLayoutParams(new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.MATCH_PARENT)); 

     for (int i = 0; i < numRows; ++i) { 
      TableRow tableRow = new TableRow(getContext()); 
      tableRow.setGravity(Gravity.CENTER); 

      tableRow.setLayoutParams(new TableLayout.LayoutParams(
        TableLayout.LayoutParams.MATCH_PARENT, 
        TableLayout.LayoutParams.MATCH_PARENT)); 

      for (int j = 0; j < numCols; ++j, ++indexListButtons) { 
       // indices 0, 1, 2, 3 
       if (indexListButtons < listButtons.size()) { 
        tableRow.addView(listButtons.get(indexListButtons)); 
       } 
       // indices 4, 5 don't exist 
       else { 
        // not enough buttons 
       } 
      } 
      addView(tableRow); 
     } 
    } 
} 

如何更改代碼，以便獲得「預期結果」？

Answer 1

您可以在TableRow子級上設置TableRow.LayoutParams中的LayoutSpan屬性，即listButtons.get（indexListButtons）。嘗試將其設置爲1.否則，您可以嘗試爲其他列插入空視圖。
