佈局 - XML：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

活動代碼：

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

    mLinearLayoutProtokoll = (LinearLayout)findViewById(R.id.linearLayoutProtokoll); 

    TableLayout.LayoutParams tableParams = new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT); 
    TableRow.LayoutParams rowParams = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT); 

    TableLayout tableLayout = new TableLayout(this); 
    tableLayout.setLayoutParams(tableParams); 

    TableRow tableRow = new TableRow(this); 
    tableRow.setLayoutParams(tableParams); 

    mTableLayout = new TableLayout(this); 
    mTableLayout.setGravity(Gravity.CENTER); 
    mTableLayout.setLayoutParams(tableParams); 

    mFileDataSource = new FileDataSource(this); 
    List<Protokoll> lAllProtokoll = mFileDataSource.loadProtokoll(); 

    TableRow lTableRow = new TableRow(this); 
    lTableRow.setLayoutParams(tableParams); 
    for (Protokoll lProtokoll : lAllProtokoll) { 
     TextView lTextViewCreated = new TextView(this); 
     lTextViewCreated.setText("date"); 
     lTextViewCreated.setLayoutParams(rowParams); 
     lTableRow.addView(lTextViewCreated); 

     TextView lTextViewType = new TextView(this); 
     lTextViewType.setLayoutParams(rowParams); 
     if (lProtokoll.getType() == 0) { 
      lTextViewType.setText("INFO"); 
     } else { 
      lTextViewType.setText("ERROR"); 
     } 
     lTableRow.addView(lTextViewType); 

     TextView lTextViewFile = new TextView(this); 
     lTextViewFile.setLayoutParams(rowParams); 
     if (lProtokoll.getFile() == null) { 
      lTextViewFile.setText(""); 
     } else { 
      lTextViewFile.setText(lProtokoll.getFile()); 
     } 
     lTableRow.addView(lTextViewFile); 

     TextView lTextViewMessage = new TextView(this); 
     lTextViewMessage.setLayoutParams(rowParams); 
     lTextViewMessage.setText(lProtokoll.getMessage()); 
     lTableRow.addView(lTextViewMessage); 

     mTableLayout.addView(lTableRow); 
    } 
    mLinearLayoutProtokoll.addView(mTableLayout); 
} 

我真的不知道什麼問題... 你能幫我嗎？

要添加的同一個錶行中的對象爲週期表的佈局：

的TableRow lTableRow =新的TableRow（本）;

將該代碼移動到「for」循環。
