java - 如何在 tablerow 内以编程方式设置 textview 的边距

Question

嘿...我正在 eclipse 上做一个项目。在这个项目中，我做了一个像这样的 xml 布局:

 <ScrollView 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"    
        tools:context=".AddRemoveMainActivity" >
    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:id="@+id/main_layout"
        >

        <!-- I will add some view programatically in this line -->

        <TableRow
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >

        <Button 
            android:id="@+id/b_add"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="Add"
             android:onClick="addItems"
            /> 
            <Button 
            android:id="@+id/b_del"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="Del"
             android:onClick="deleteItems"
            />     
        </TableRow>
    </LinearLayout>    
    </ScrollView>

关于我的主要 Activity :

public class AddRemoveMainActivity extends Activity {
    Button add,del;
    LinearLayout ll;
    private String[] spinnerContent = {"Ikan","Udang","Kepiting","Kerang"};

    private int count = 0;
    private int line = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_remove_main);

        ll = (LinearLayout) findViewById(R.id.main_layout); 

    }

    public void addItems(View view)
    {
        count++;

        final LinearLayout frame = new LinearLayout(this);
        frame.setOrientation(LinearLayout.VERTICAL);
        frame.setId(count);

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,spinnerContent);

        final TableRow row1 = new TableRow(this);           

        Spinner spin = new Spinner(this);
        TextView jenis = new TextView(this);
        TextView keterangan = new TextView(this);
        TextView total = new TextView(this);


        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
        params.setMargins(0, 13, 17, 9);


        spin.setAdapter(adapter);
        jenis.setText("Jenis : "+Integer.toString(count));
        //jenis.setLayoutParams(params);
        keterangan.setText("Keterangan : ");
        total.setText("Jumlah(kg) :");

        row1.addView(jenis);
        row1.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
        //ViewGroup.MarginLayoutParams mlp = (ViewGroup.MarginLayoutParams)jenis.getLayoutParams();
        //mlp.setMargins(37, 13, 17, 0);


        row1.addView(spin);

        frame.addView(row1);

        ll.addView(frame, line);
        line++;

    }


    public void deleteItems(View view)
    {
        if(count > 0)
        {
            final LinearLayout temp = (LinearLayout)ll.findViewById(count);
            temp.removeAllViews();
            ll.removeView(temp);
            count--;
            line--;
        }
    }

正如您从我的 mainActivity 中看到的，我已将 textview(jenis) 和 spinner(spin) 添加到 tableRow，然后将该 tableRow 添加到 LinearLayout(frame)，然后将该框架添加到来自 xml 的 LinearLayout文件上方的两个按钮(添加&删除按钮)...... 我的问题是我只想在 TextView (jenis)和(Spinner)旋转之间添加边距。正如您从我的 mainActivity 中再次看到的，我尝试使用:

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
            params.setMargins(0, 13, 17, 9);
...
...
...
jenis.setLayoutParams(params);

但是这个不起作用......我尝试了另一种方法，但它也不起作用:

//ViewGroup.MarginLayoutParams mlp = (ViewGroup.MarginLayoutParams)jenis.getLayoutParams();
            //mlp.setMargins(37, 13, 17, 0);

那么有什么想法或其他方法可以为我的 TextView 添加边距......？？？ 预先感谢...:-)

尝试下面的代码，让我知道它是否有效

android.widget.TableRow.LayoutParams layoutParams = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT);
    layoutParams.setMargins(0, 13, 17, 9);
    row1.addView(jenis, layoutParams);
    //ViewGroup.MarginLayoutParams mlp = (ViewGroup.MarginLayoutParams)jenis.getLayoutParams();
    //mlp.setMargins(37, 13, 17, 0);


    row1.addView(spin, layoutParams);
