带有ListView和按钮的Android布局

Question

好吧，这种特定的布局让我很烦。而且似乎找不到找到listView的方法，在底部有一行按钮，这样listview不会延伸到按钮的上方，因此这些按钮始终固定在屏幕的底部。这就是我想要的：

似乎应该这么简单，但是我尝试过的所有方法都失败了。有什么帮助吗？

这是我当前的代码：

    RelativeLayout container = new RelativeLayout(this);
    container.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));

    //** Add LinearLayout with button(s)

    LinearLayout buttons = new LinearLayout(this);

    RelativeLayout.LayoutParams bottomNavParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    bottomNavParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    bottomNavParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
    buttons.setLayoutParams(bottomNavParams);


    ImageButton newLayer = new ImageButton(this);
    newLayer.setImageResource(R.drawable.newlayer);
    newLayer.setLayoutParams(new LinearLayout.LayoutParams(45, LayoutParams.FILL_PARENT));
    buttons.addView(newLayer);

    container.addView(buttons);

    //** Add ListView

    layerview = new ListView(this);

    RelativeLayout.LayoutParams listParams = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    listParams.addRule(RelativeLayout.ABOVE, buttons.getId());

    layerview.setLayoutParams(listParams);

    container.addView(layerview);

我认为这就是您想要的。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent">

    <Button android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:id="@+id/testbutton"
        android:text="@string/hello" android:layout_alignParentBottom="true" />

    <ListView android:layout_width="fill_parent"
        android:layout_height="fill_parent" android:id="@+id/list"
        android:layout_alignParentTop="true" android:layout_above="@id/testbutton" />

</RelativeLayout>
