android 怎么获取音乐专辑图像

这是抽取专辑的方法，扫描歌曲的时候自己把歌曲的id和专辑的id传进去就能获取

private static final Uri sArtworkUri = Uri

parse("content://media/external/audio/albumart");

/

将MP3里读取出来

@param context

@param songid

@param albumid

@return

/

public static Bitmap getMusicBitemp(Context context, long songid,

long albumid) {

Bitmap bm = null;

// 专辑id和歌曲id小于0说明没有专辑、歌曲，并抛出异常

if (albumid < 0 && songid < 0) {

throw new IllegalArgumentException(

"Must specify an album or a song id");

}

try {

if (albumid < 0) {

Uri uri = Uriparse("content://media/external/audio/media/"

+ songid + "/albumart");

ParcelFileDescriptor pfd = contextgetContentResolver()

openFileDescriptor(uri, "r");

if (pfd != null) {

FileDescriptor fd = pfdgetFileDescriptor();

bm = BitmapFactorydecodeFileDescriptor(fd);

}

} else {

Uri uri = ContentUriswithAppendedId(sArtworkUri, albumid);

ParcelFileDescriptor pfd = contextgetContentResolver()

openFileDescriptor(uri, "r");

if (pfd != null) {

FileDescriptor fd = pfdgetFileDescriptor();

bm = BitmapFactorydecodeFileDescriptor(fd);

} else {

return null;

}

}

} catch (FileNotFoundException ex) {

}

return bm;

}

另一种：

// 查找sdcard卡上的所有歌曲信息

public List> getMultiData() {

ArrayList> musicList = new ArrayList>();

// 加入封装音乐信息的代码

// 查询所有歌曲

ContentResolver musicResolver = thisgetContentResolver();

Cursor musicCursor = musicResolverquery(

MediaStoreAudioMediaEXTERNAL_CONTENT_URI, null, null, null,

null);

int musicColumnIndex;

if (null != musicCursor && musicCursorgetCount() > 0) {

for (musicCursormoveToFirst(); !musicCursorisAfterLast(); musicCursor

moveToNext()) {

Map musicDataMap = new HashMap();

Random random = new Random();

int musicRating = Mathabs(randomnextInt()) % 10;

musicDataMapput("musicRating", musicRating);

// 取得音乐播放路径

musicColumnIndex = musicCursor

getColumnIndex(MediaStoreAudioAudioColumnsDATA);

musicPath = musicCursorgetString(musicColumnIndex);

musicDataMapput("musicPath", musicPath);

// 取得音乐的名字

musicColumnIndex = musicCursor

getColumnIndex(MediaStoreAudioAudioColumnsTITLE);

musicName = musicCursorgetString(musicColumnIndex);

musicDataMapput("musicName", musicName);

// 取得音乐的专辑名称

musicColumnIndex = musicCursor

getColumnIndex(MediaStoreAudioAudioColumnsALBUM);

musicAlbum = musicCursorgetString(musicColumnIndex);

musicDataMapput("musicAlbum", musicAlbum);

// 取得音乐的演唱者

musicColumnIndex = musicCursor

getColumnIndex(MediaStoreAudioAudioColumnsARTIST);

musicArtist = musicCursorgetString(musicColumnIndex);

musicDataMapput("musicArtist", musicArtist);

// 取得歌曲对应的专辑对应的Key

musicColumnIndex = musicCursor

getColumnIndex(MediaStoreAudioAudioColumnsALBUM_KEY);

musicAlbumKey = musicCursorgetString(musicColumnIndex);

String[] argArr = { musicAlbumKey };

ContentResolver albumResolver = thisgetContentResolver();

Cursor albumCursor = albumResolverquery(

MediaStoreAudioAlbumsEXTERNAL_CONTENT_URI, null,

MediaStoreAudioAudioColumnsALBUM_KEY + " = ",

argArr, null);

if (null != albumCursor && albumCursorgetCount() > 0) {

albumCursormoveToFirst();

int albumArtIndex = albumCursor

getColumnIndex(MediaStoreAudioAlbumColumnsALBUM_ART);

musicAlbumArtPath = albumCursorgetString(albumArtIndex);

if (null != musicAlbumArtPath

&& !""equals(musicAlbumArtPath)) {

musicDataMapput("musicAlbumImage", musicAlbumArtPath);

} else {

musicDataMapput("musicAlbumImage",

"file:///mnt/sdcard/albjpg");

}

} else {

// 没有专辑定义，给默认

musicDataMapput("musicAlbumImage",

"file:///mnt/sdcard/albjpg");

}

musicListadd(musicDataMap);

}

}

return musicList;

}

1、实现原理:用户打开相册或相机选择相片后,相片经过压缩并设置在控件上,在本地sd卡存一份(如果有的话,没有则内部存储,所以还

需要判断用户是否挂载了sd卡),然后在服务器上存储一份该,当下次再次启动应用时,会默认去sd卡加载该,如果本地没有,再会去联网请求

2、使用了picasso框架以及自定义BitmapUtils工具类

3、记得加上相关权限

<uses-permission android:name="androidpermissionINTERNET"></uses-permission>

<uses-permission android:name="androidpermissionCAMERA"/>

<uses-permission android:name="androidpermissionWRITE_EXTERNAL_STORAGE"></uses-permission>

以上所述是小编给大家介绍的Android实现调用系统图库与相机设置头像并保存在本地及服务器 ，希望对大家有所帮助

String path = cursorgetString(column_index);改为

String path = cursorgetString(column_index-1);试试

最近做项目要通过的绝对路径找到的URI，然后删除，小小总结一下获取URI的方法，亲自试验在

android 413的系统上都是可用的。

1将所有的路径取出，遍历比较找到需要的路径，取出URI，效率较低

其中 MediaStoreMediaColumnsDATA 字段存的就是的绝对路径，

最后mImageUri得到的就是的URI

1 Uri mUri = Uriparse("content://media/external/images/media");

2 Uri mImageUri = null;

3 Cursor cursor = managedQuery(

4 MediaStoreImagesMediaEXTERNAL_CONTENT_URI, null, null, null,

5 MediaStoreImagesMediaDEFAULT_SORT_ORDER);

6 cursormoveToFirst();

7

8 while (!cursorisAfterLast()) {

9 String data = cursorgetString(cursor

10 getColumnIndex(MediaStoreMediaColumnsDATA));

11 if (picPathequals(data)) {

12 int ringtoneID = cursorgetInt(cursor

13 getColumnIndex(MediaStoreMediaColumns_ID));

14 mImageUri = UriwithAppendedPath(mUri, "" + ringtoneID);

15 break;

16 }

17 cursormoveToNext();

18 }

2直接从媒体数据库根据字段取出相应的记录，效率较高

1 //TYLT: add by duanyf 20121027 start

2 String type = UtilsensureNotNull(intentgetType());

3 Logd(TAG, "uri is " + uri);

4 if (urigetScheme()equals("file") && (typecontains("image/")))

{

5 String path = urigetEncodedPath();

6 Logd(TAG, "path1 is " + path);

7 if (path != null) {

8 path = Uridecode(path);

9 Logd(TAG, "path2 is " + path);

10 ContentResolver cr = thisgetContentResolver();

11 StringBuffer buff = new StringBuffer();

12 buffappend("(")

13 append(ImagesImageColumnsDATA)

14 append("=")

15 append("'" + path + "'")

16 append(")");

17 Cursor cur = crquery(

18 ImagesMediaEXTERNAL_CONTENT_URI,

19 new String[] { ImagesImageColumns_ID },

20 bufftoString(), null, null);

21 int index = 0;

22 for (curmoveToFirst(); !curisAfterLast(); cur

23 moveToNext()) {

24 index = curgetColumnIndex(ImagesImageColumns_ID);

25 // set _id value

26 index = curgetInt(index);

27 }

28 if (index == 0) {

29 //do nothing

30 } else {

31 Uri uri_temp = Uri

32 parse("content://media/external/images/media/"

33 + index);

34 Logd(TAG, "uri_temp is " + uri_temp);

35 if (uri_temp != null) {

36 uri = uri_temp;

37 }

38 }

39 }

40 }

41 //TYLT: add by duanyf 20121027 end

3直接根据路径通过 ContentProvider 的 delete() 方法删除，两行代码搞定，效率最高

1 String params[] = new String[]{filepath};

2

ctxgetContentResolver()delete(MediaStoreImagesMediaEXTERNAL_CONTENT_URI,

MediaStoreImagesMediaDATA + " LIKE ", params);

在Android开发中,我经常会遇到需要获取手机通讯录联系人信息,Android手机的通讯录联系人全部都存在系统的数据库中，如果须要获得通讯里联系人的信息就须要访问系统的数据库，才能将信息获取出来。

拍拍贷如何获取联络人

拍拍贷app 可以获取你的通讯录，新浪有借也一样

而且更加好用

它的话是利息按日计，随时还款。

而一般的网贷如借10000，按照目前不低的年化收益率10%来计算的话， 一个月利息是83左右。 计算公式你记一下 10000x10%=1000（这里得出的是一年的收益） 1000/12=83 （除以12个月，才得到你一个月的）

微锁屏获取联络人资讯有风险吗

国内的很多软体都申请了很多不需要的许可权，锁屏软体应该是不需要读取联络人资讯的，可以安装一些软体取消锁屏软体的读取联络人许可权。

android怎么获取联络人头像

必须先编辑成正方形，或你的联络人有自动减取功能，不然头像肯定变形!

手机常显示易信正在尝试获取联络人资讯

这应该是易信在读取你的联络人，以便获取已经用手机号码注册了易信的手机上的联络人，可以考虑解除安装易信（如果不经常用的话）其实很多软体都喜欢读取个人资讯。。

为什么百度HI新增联络人时总是正在获取联络人资讯

应该是网速慢，如果你确定你的网速正常，那有可能是百度系统出错了。

我也遇到过这种情况。

还有一种可能，就是你新增的联络人不存在，或名字输入错误。

什么软体可以汇出联络人所有资讯

360手机卫士、qq都提供了云端备份通讯录的功能。现在备份到云端伺服器上是最安全的，永远不会丢失，换手机前备份一下，新手机上就可以下载到。平日经常备份联络人资讯，安全可靠有保障。

实现思维路径：

以进入相机拍照的思维路线为例子：

1进入app

2判断之前是否保存头像，如果有就显示历史图像 (下面代码中在getOldAvatar();方法中执行这个逻辑)

3点击更换图像的Button或者布局，启动对话框(下面代码中在dialogueBox();方法执行这个逻辑)

4系统版本判断授权方式(静态还是动态授权)，判断之前是否已经授权 （setPermissions(Permissions_CAMERA_KEY);这个方法执行授权逻辑）

5如果是首次授权，就执行首次授权完成后马上运行的回调方法 onRequestPermissionsResult

5判断完成不管是否是首次授权还是之前就是授权过了都要执行enterCamera();方法启动相机并且发送携带数据的请求

6启动相机完成后，并且拍照完成退出相机，都要运行Intent返回数据请求回调方法onActivityResult。将传入的数据传入到cropPhoto(datagetData());方法里去执行剪裁。

7在cropPhoto方法里将携带数据跳转到裁剪界面中裁剪，裁剪完成后又要回到onActivityResult回调方法里，执行裁剪完的数据回调工作。

8在onActivityResult回调方法里，裁剪完的将运行setPicToView 方法保存。保存的将在下次启动activity时作为历史头像调用。

保存到本地的Lua代码需要经过以下步骤：

1 导入相关库文件

首先需要导入相关库文件，包括cocos2d-x库和io库。这可以通过在代码开头添加以下代码实现：

local FileUtils = ccFileUtils:getInstance()

local io = require("io")

2 获取数据

接下来需要获取需要保存的的数据。这可以通过使用cocos2d-x中的Sprite类来实现：

local sprite = ccSprite:create("imagepng")

local texture2D = sprite:getTexture()

local size = texture2D:getContentSizeInPixels()

local data = texture2D:getData()

3 将数据写入文件

最后一步是将获取到的数据写入文件。这可以通过使用io库中的文件 *** 作函数来实现：

local path = FileUtils:getWritablePath() "imagepng"

local file = ioopen(path, "wb")

file:write(data, size)

file:close()

这段代码会将获取到的数据写入一个名为imagepng的文件中，保存在应用的可写目录下。需要注意的是，在写入文件之前需要先创建一个io文件对象，并且在写入完成之后需要关闭文件对象。

以上就是将保存到本地的Lua代码的详细步骤。
