FloatingActionButton在github上的项目主页是:https://github.com/makovkastar/FloatingActionButton

它的依赖包NineOldAndroids在github上的项目主页是:https://github.com/JakeWharton/NineOldAndroids

(导包的时候注意要把android-support-v7-appcompat作为它的一个Library,不要重复了NineOldAndroids的引用)

 

测试代码:

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    xmlns:fab="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.zzw.testfloatingactionbutton.MainActivity" >    <ListView        android:id="@+id/listView"        android:layout_width="match_parent"        android:layout_height="match_parent" />    <com.melnykov.fab.FloatingActionButton        android:id="@+id/fab"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:layout_alignParentRight="true"        android:layout_margin="16dip"        android:src="@drawable/ic_launcher"        fab:fab_shadow="true"        fab:fab_type="normal" /></RelativeLayout>

MainActivity.java:

package com.zzw.testfloatingactionbutton;import com.melnykov.fab.FloatingActionButton;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.ArrayAdapter;import android.widget.ListView;import android.widget.Toast;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                String[] data=new String[100];          for(int i=0;i<data.length;i++){              data[i]="ZZW1994"+i;          }                    ListView listView=(ListView) findViewById(R.id.listView);                    ArrayAdapter adapter=new ArrayAdapter(this,android.R.layout.simple_list_item_1,data);          listView.setAdapter(adapter);                    //附着在ListView,跟随ListView滚动滑入滑出          FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);          fab.attachToListView(listView);          fab.setColorPressed(0xffb71c1c);                         fab.setOnClickListener(new OnClickListener() {                        @Override            public void onClick(View v) {                Toast.makeText(getApplicationContext(), "hello", 0).show();                            }        });    }}
