闲话不多说，直接上代码：

FloatingViewApp.java：

package com.cn.lhq;import android.app.ListActivity;import android.os.Bundle;import android.widget.ArrayAdapter;public class FloatingViewApp extends ListActivity {@Overridepublic void onCreate(Bundle icicle) {super.onCreate(icicle);setContentView(R.layout.main);String[] mStrings = new String[] { "Item 1", "Item 2", "Item 3","Item 4", "Item 5", "Item 6", "Item 7", "Item 8", "Item 9","Item 10", "Item 11", "Item 12" };this.setListAdapter(new ArrayAdapter(this,android.R.layout.simple_list_item_1, mStrings));}}

main.xml：

<?xml version="1.0" encoding="UTF-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <TextView android:id="@android:id/empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="123"/> </LinearLayout> <Button android:id="@+id/floating_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="悬浮按钮" android:padding="5dip" android:layout_margin="5dip" android:layout_gravity="right|bottom" /> </FrameLayout>
