我要的是一个简单的3栏表格，第1页的标题是 “等级”， “PERCENTAGE”和“SCORE”。后来我会从SQLite数据库中取出10多行，但我会在之后解决这个问题。

您的xml文件将被编辑;

我想在XML中初始化TableLayout，然后以编程方式填充它。这是我的XML，Java和LogCat输出。

highscoresmain.xml

<TableLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id = "@+id/tableLayout" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_weight="0" 
    android:padding="5dp"> 


    </TableLayout>

榜类内容;

public class Highscores extends Activity { 

    TableLayout table; 
    TableRow rowHeader, row1, row2, row3, row4, row5, row6, row7, row8, row9, row10; 
    TextView rank, percentage, score; 
    Button btn1;  

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.highscoresmain); 

     TableLayout table = (TableLayout)findViewById(R.id.tableLayout); 

     TextView rank = new TextView(this); 
     rank.setText("RANK"); 
     TextView percentage = new TextView(this); 
     percentage.setText("PERCENTAGE"); 
     TextView score = new TextView(this); 
     score.setText("SCORE"); 

     TableRow rowHeader = new TableRow(this); 

     rowHeader.addView(rank); //Line 39 
     rowHeader.addView(percentage); 
     rowHeader.addView(score); 

     Button btn1 = (Button)findViewById(R.id.homeBtn); 

     table.addView(rowHeader); 

     btn1.setOnClickListener(new OnClickListener() { 
      public void onClick(View arg0) { 
       Intent intent = new Intent(Highscores.this, MainMenu.class); 
       startActivity(intent); 
      } 
     }); 
    } 
}

当我调用TableLayout的addview它会例外。为什么？ – ofskyMohsen

您是否添加了哪个视图以及如何操作？ – nurisezgin

我想添加包含两个文本视图的表格行 – ofskyMohsen

你不需要下面的代码：

TableRow rowHeader = (TableRow)findViewById(R.id.rowHeader); 

rowHeader.addView(rank); //Line 39 
rowHeader.addView(percentage); 
rowHeader.addView(score);

table.addView(rowHeader, new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

由于他们是在布局中已定义。

答案就在你的logcat：

了java.lang.RuntimeException：无法启动活动 ComponentInfo {com.example.test/com.example.test.Highscores}：的java.lang。 IllegalStateException：指定的子项已具有父级。您必须先调用子对象的父对象的removeView（）。

的TextView s为已经TableRow里面，如果你想以编程方式填充它，只是删除您TableLayout的所有孩子，在代码中创建它们，并添加他们Activity的onCreate，你只是做。

祝你好运！
