带有 ListView 和按钮的 Android 布局 [英] Android Layout with ListView and Buttons

问题描述

好吧，这个特定的布局让我很烦.并且似乎无法找到一种方法来拥有一个 listView，在底部有一排按钮，这样 listview 就不会延伸到按钮的顶部，所以按钮总是捕捉到屏幕的底部.这是我想要的:

Alright, this specific layout is just annoying me. And can't seem to find a way to have a listView, with a row of buttons at the bottom so that the listview doesn't extend over top of the buttons, and so the buttons are always snapped to the bottom of the screen. Here's what I want:

看起来应该很容易，但我尝试过的一切都失败了.有什么帮助吗?

It seems like it should be so easy, but everything I've tried has failed. Any help?

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);

推荐答案

我认为这就是您要找的.

I think this is what you are looking for.

<?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>
