论强大当然是c了，但是c偏向底层，以简小精炼著称，很多程序需要用到已有的功能需要庞大的函数库支持，这一点c就不行了。因此说，c理论上无所不能，但是只有在底层编程...
大家还关注音乐播放器的实现,框架的基本搭建,资源 - 博客频道 - CSDN.NET

你们肯定会说没图我怎么做...那好吧 我压缩一下藏在百度云把是整体的所有图片哦 有的可能用不到
链接：/s/1mhOXk4g 密码：7t92有的人肯定比我还懒 &我就想要个apk 或者我就想要个项目 好吧 你赢了 我给你地址 我用的开发工具是androidStudio
链接：/s/1pLbIjMV 密码：55in
他是从vbFragmen里面跳进去的 所以 得从Main说起 我把完整的项目结构拷贝进来了 然后就实现音乐
我把重要的类写出来 &如果想看全部的话 可以下载上面有地址

public class MusicAdapter extends CursorAdapter {
//不推荐第三个参数是boolean 如果第三个传入true当Currsor发生改变 会自动调用requery刷新界面

超级简单的Fragment的封装
BaseFragment
一般有集合的地方 就有数据bean
歌词的数据bean
package com.example.liuan.phonevideo.
* Name: Lyric
* Author: liuan
* creatTime: 10:51
public class Lyric implements Comparable&Lyric& {
* 一行歌词的文字
* 当前行歌词开始演唱的时刻
public Lyric(String text, int time) {
this.text =
this.time =
public int compareTo(Lyric o) {
return this.time-o.
音乐条目的数据bean
package com.example.liuan.phonevideo.
import android.database.C
import android.provider.MediaS
import java.io.S
* Name: MusicItem
* Author: liuan
* creatTime: 14:53
public class MusicItem implements Serializable{
public String displayN
public static MusicItem getMusicFromCursor(Cursor cursor){
if(cursor==null){
MusicItem musicItem = new MusicItem();
musicItem.data=cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
musicItem.title=cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
musicItem.artist=cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
musicItem.size=cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Media.SIZE));
musicItem.duration=cursor.getInt(cursor.getColumnIndex(MediaStore.Audio.Media.DURATION));
if(musicItem.title.contains(&-&)){
musicItem.artist= musicItem.title.split(&-&)[0].trim();
musicItem.title= musicItem.title.split(&-&)[1].trim();
musicItem.displayName=cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
return musicI
如果音乐列表太大的话 会阻塞主线程 一般不会用的是数据库 解决方案
MyAsyncQueryHandler
package com.example.liuan.phonevideo.
import android.content.AsyncQueryH
import android.content.ContentR
import android.database.C
import com.example.liuan.phonevideo.adapter.MusicA
* Name: MyAsyncQueryHandler
* Author: liuan
* creatTime: 14:45
public class MyAsyncQueryHandler extends AsyncQueryHandler {
public MyAsyncQueryHandler(ContentResolver cr) {
super(cr);
protected void onQueryComplete(int token, Object cookie, Cursor cursor) {
super.onQueryComplete(token, cookie, cursor);
MusicAdapter adapter = (MusicAdapter)
//替换旧的游标 如果旧的游标不为空 会关闭
adapter.changeCursor(cursor);
//替换旧的游标 把旧的游标作为返回值 返回 不会关闭
adapter.swapCursor(cursor);

论强大当然是c了，但是c偏向底层，以简小精炼著称，很多程序需要用到已有的功能需要庞大的函数库支持，这一点c就不行了。因此说，c理论上无所不能，但是只有在底层编程...

你们肯定会说没图我怎么做...那好吧 我压缩一下藏在百度云把是整体的所有图片哦 有的可能用不到
链接：/s/1mhOXk4g 密码：7t92有的人肯定比我还懒 &我就想要个apk 或者我就想要个项目 好吧 你赢了 我给你地址 我用的开发工具是androidStudio
链接：/s/1pLbIjMV 密码：55in
他是从vbFragmen里面跳进去的 所以 得从Main说起 我把完整的项目结构拷贝进来了 然后就实现音乐
我把重要的类写出来 &如果想看全部的话 可以下载上面有地址

超级简单的Fragment的封装
BaseFragment
一般有集合的地方 就有数据bean
歌词的数据bean
package com.example.liuan.phonevideo.
* Name: Lyric
* Author: liuan
* creatTime: 10:51
public class Lyric implements Comparable&Lyric& {
* 一行歌词的文字
* 当前行歌词开始演唱的时刻
public Lyric(String text, int time) {
this.text =
this.time =
public int compareTo(Lyric o) {
return this.time-o.
音乐条目的数据bean
package com.example.liuan.phonevideo.
import android.database.C
import android.provider.MediaS
import java.io.S
* Name: MusicItem
* Author: liuan
* creatTime: 14:53
public class MusicItem implements Serializable{
public String displayN
public static MusicItem getMusicFromCursor(Cursor cursor){
if(cursor==null){
MusicItem musicItem = new MusicItem();
musicItem.data=cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
musicItem.title=cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
musicItem.artist=cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
musicItem.size=cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Media.SIZE));
musicItem.duration=cursor.getInt(cursor.getColumnIndex(MediaStore.Audio.Media.DURATION));
if(musicItem.title.contains(&-&)){
musicItem.artist= musicItem.title.split(&-&)[0].trim();
musicItem.title= musicItem.title.split(&-&)[1].trim();
musicItem.displayName=cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
return musicI
如果音乐列表太大的话 会阻塞主线程 一般不会用的是数据库 解决方案

//替换旧的游标 如果旧的游标不为空 会关闭

//替换旧的游标 把旧的游标作为返回值 返回 不会关闭
