android:使用LayoutParams设置按钮之间的边距

我想在按钮之间自动生成垂直按钮,底边距为20px。我尝试使用LayoutParams对象设置边距,但没有成功。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/regions_search"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_marginBottom="30dip"
    android:orientation="vertical" >
</LinearLayout>



@Override
public void onCreate(Bundle savedInstanceState) {

    ...

    for (Region region : regionsList) {

        //create new button     
        Button button = new Button(mContext);

        //set infos
        int id = Integer.parseInt(Long.toString((Long) region.getId()));        button.setId(id);
        button.setText(region.getName() + "( " + region.getStores_nb() + " )");

        //Layoutparams setting
        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
        params.setMargins(0, 0, 0, 20);

        button.setLayoutParams(params);

        myLinear.addView(button);

        }

正如您在图像上看到的那样,图像之间没有空间。有人知道为什么吗? 谢谢 ! enter image description here

你可以试试这个:

LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) button.getLayoutParams();
layoutParams.bottomMargin += 20;
button.setLayoutParams(layoutParams);

尝试使用LinearLayout.LayoutParams代替FrameLayout.LayoutParams,就像使用LinearLayout的xml一样。

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
