Question

내가 정확히 뭐하는 거지 무슨 원인이 페이지는 말한다 : http://en.androidwiki.com/wiki/Dynamically_adding_rows_to_TableLayout

주요 코드 :

 
this.setContentView(R.layout.main);
 

 /* Find Tablelayout defined in main.xml */ 
     TableLayout tl = (TableLayout)findViewById(R.id.myTableLayout); 
      /* Create a new row to be added. */ 
      TableRow tr = new TableRow(this); 
      tr.setLayoutParams(new LayoutParams(
          LayoutParams.FILL_PARENT, 
          LayoutParams.WRAP_CONTENT)); 
       /* Create a Button to be the row-content. */ 
       Button b = new Button(this); 
       b.setText("Dynamic Button"); 
       b.setLayoutParams(new LayoutParams(
          LayoutParams.FILL_PARENT, 
          LayoutParams.WRAP_CONTENT)); 
       /* Add Button to row. */ 
       tr.addView(b); 
     /* Add row to TableLayout. */ 
     tl.addView(tr,new TableLayout.LayoutParams(
       LayoutParams.FILL_PARENT, 
       LayoutParams.WRAP_CONTENT)); <code> 
 

XML :
 

<?xml version="1.0" encoding="utf-8"?> 
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/myTableLayout" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    > 
    <TableRow 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content"> 

      <Button android:text="Static Button"/> 
    </TableRow> 
</TableLayout> 

을하지만 때 내가 중복 라인 tr.addView (b);

나를 제공합니다. 어디에서 오류가 발생했는지 알 수 있습니까?

Answer 1

동일한 버튼을 추가했기 때문입니다. 시도해보십시오 :

  ..... 
      /* Create a Button to be the row-content. */ 
      Button b = new Button(this); 
      b.setText("Dynamic Button"); 
      b.setLayoutParams(new LayoutParams(
         LayoutParams.WRAP_CONTENT, 
         LayoutParams.WRAP_CONTENT)); 
      /* Add Button to row. */ 
      tr.addView(b); 

      b = new Button(this); 
      b.setText("Another Dynamic Button"); 
      b.setLayoutParams(new LayoutParams(
         LayoutParams.WRAP_CONTENT, 
         LayoutParams.WRAP_CONTENT)); 
      /* Add Button to row. */ 
      tr.addView(b); 

      ......
