CODE：

private TableLayout Table;//in XML 

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

       //here I define the TR params 
     Table=(TableLayout)findViewById(R.id.Table); 
     TableLayout.LayoutParams tableRowParams=new TableLayout.LayoutParams 
(TableLayout.LayoutParams.MATCH_PARENT,TableLayout.LayoutParams.MATCH_PARENT,1.0f); 
      //fill the table with Table rows dynamicly 
    for(int i=0;i<N;i++){ 


     TableRow TR= new TableRow(this); 
     TR.setLayoutParams(tableRowParams); 
     Table.addView(TR); 
     //Table Row contains EditText and ImageView 
        EditText editText1 =new EditText(this); 
     ImageView imgview=new ImageView(this); 
     TR.addView(editText1); 
     TR.addView(imgview); 

     editText1.setText("foo"); 
     editText1.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,1.0f)); 

     int id = getResources().getIdentifier("com.example.university2:drawable/news1", null, null); 


     imgview.setImageResource(id); 
     imgview.setAdjustViewBounds(true); 
     imgview.setMaxHeight(50); 
     imgview.setMaxWidth(50); 

     imgview.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,1.0f)); 


    } 

}

这里是XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" > 

<ScrollView 
    android:id="@+id/scrollView1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentRight="true" 
    android:layout_alignParentTop="true" > 

    <TableLayout 
     android:id="@+id/Table" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" > 
    </TableLayout> 

</ScrollView>

我会感谢你的帮助。谢谢。

尝试TableRow.LayoutParams .. –

究竟在哪里？ –

将TableLayout.LayoutParams替换为TableRow.LayoutParams ... –

看起来这个问题是由TR.setLayoutParams(tableRowParams);
（java.lang.ClassCastException：android.widget.TableLayout $的LayoutParams不能转换到android.widget.TableRow $的LayoutParams）引起
becouse tableRowParams（声明：TableLayout.LayoutParams tableRowParams）是不TableRow.LayoutParams
尝试更换

TableLayout.LayoutParams tableRowParams=new TableLayout.LayoutParams (TableLayout.LayoutParams.MATCH_PARENT,TableLayout.LayoutParams.MATCH_PARENT,1.0f);

与（更新）

TableRow.LayoutParams tableRowParams=new TableRow.LayoutParams (TableRow.LayoutParams.MATCH_PARENT,TableRow.LayoutParams.MATCH_PARENT,1.0f);

和编辑

TR.addView(editText1, new TableRow.LayoutParams (TableRow.LayoutParams.MATCH_PARENT,TableRow.LayoutParams.MATCH_PARENT,1.0f)); 
TR.addView(imgview, new TableRow.LayoutParams (TableRow.LayoutParams.MATCH_PARENT,TableRow.LayoutParams.MATCH_PARENT,1.0f));

删除

imgview.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,1.0f));

和

editText1.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,1.0f));

问题是由不正确的创作引起将特定控件的LayoutParams添加到特定所有者，例如：如果您将控件添加到LinearLayout - 您应该为该控件使用LinearLayout.LayoutParams，TableLayout.LayoutParams - 如果您将控件添加到TableLayout，...等等...
