Android获取手机内的所有图片和视频

1.获取手机本地所有图片

/**
* 获取本地所有的图片
*
* @return list
*/
public static List<Material> getAllLocalPhotos(Context context, int uid) {
long totalUploadCount = MPSManager.getInstance(context).getMpsRecordCount(uid) + 1000;
List<Material> list = new ArrayList<>();
String[] projection = {
MediaStore.Images.Media.DATA,
MediaStore.Images.Media.DISPLAY_NAME,
MediaStore.Images.Media.SIZE
};
//全部图片
String where = MediaStore.Images.Media.MIME_TYPE + "=? or "
+ MediaStore.Images.Media.MIME_TYPE + "=? or "
+ MediaStore.Images.Media.MIME_TYPE + "=?";
//指定格式
String[] whereArgs = { "image/jpeg", "image/png", "image/jpg"};
//查询
Cursor cursor = context.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, where, whereArgs,
MediaStore.Images.Media.DATE_MODIFIED + " desc ");
if (cursor == null) {
return list;
}
//遍历
while (cursor.moveToNext()) {
Material materialBean = new Material();
//获取图片的名称
materialBean.setTitle(cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DISPLAY_NAME)));
long size = cursor.getLong(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.SIZE)); // 大小

//获取图片的生成日期
byte[] data = cursor.getBlob(cursor.getColumnIndex(MediaStore.Images.Media.DATA));

String path = new String(data, 0, data.length - 1);
File file = new File(path);

if (size < 5 * 1024 * 1024) { //<5M
long time = file.lastModified();
SimpleDateFormat format = new SimpleDateFormat( "yyyy-MM-dd HH:mm");
String t = format.format(time);
materialBean.setTime(t);
materialBean.setLogo(path);
materialBean.setFilePath(path);
materialBean.setFileSize(size);
materialBean.setChecked( false);
materialBean.setFileType( 6);
materialBean.setFileId(totalUploadCount++);
materialBean.setUploadedSize( 0);
materialBean.setTimeStamps(System.currentTimeMillis() + "");
list.add(materialBean);
}
}
cursor.close();
return list;
}

2.获取手机本地所有视频

/**
* 获取本地所有的视频
*
* @return list
*/
public static List<Material> getAllLocalVideos(Context context, int uid) {
long totalUploadCount = MPSManager.getInstance(context).getMpsRecordCount(uid) + 1000;
String[] projection = {
MediaStore.Video.Media.DATA,
MediaStore.Video.Media.DISPLAY_NAME,
MediaStore.Video.Media.DURATION,
MediaStore.Video.Media.SIZE
};
//全部图片
String where = MediaStore.Images.Media.MIME_TYPE + "=? or "
+ MediaStore.Video.Media.MIME_TYPE + "=? or "
+ MediaStore.Video.Media.MIME_TYPE + "=? or "
+ MediaStore.Video.Media.MIME_TYPE + "=? or "
+ MediaStore.Video.Media.MIME_TYPE + "=? or "
+ MediaStore.Video.Media.MIME_TYPE + "=? or "
+ MediaStore.Video.Media.MIME_TYPE + "=? or "
+ MediaStore.Video.Media.MIME_TYPE + "=? or "
+ MediaStore.Video.Media.MIME_TYPE + "=?";
String[] whereArgs = { "video/mp4", "video/3gp", "video/aiv", "video/rmvb", "video/vob", "video/flv",
"video/mkv", "video/mov", "video/mpg"};
List<Material> list = new ArrayList<>();
Cursor cursor = context.getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
projection, where, whereArgs, MediaStore.Video.Media.DATE_ADDED + " DESC ");
if (cursor == null) {
return list;
}
try {
while (cursor.moveToNext()) {
long size = cursor.getLong(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.SIZE)); // 大小
if (size < 600 * 1024 * 1024) { //<600M
Material materialBean = new Material();
String path = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA)); // 路径
long duration = cursor.getInt(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DURATION)); // 时长
materialBean.setTitle(cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media.DISPLAY_NAME)));
materialBean.setLogo(path);
materialBean.setFilePath(path);
materialBean.setChecked( false);
materialBean.setFileType( 2);
materialBean.setFileId(totalUploadCount++);
materialBean.setUploadedSize( 0);
materialBean.setTimeStamps(System.currentTimeMillis() + "");
SimpleDateFormat format = new SimpleDateFormat( "HH:mm:ss");
format.setTimeZone(TimeZone.getTimeZone( "GMT+0"));
String t = format.format(duration);
materialBean.setTime(context.getString(R.string.video_len) + t);
materialBean.setFileSize(size);
list.add(materialBean);
}
}
} catch (Exception e) {
e.printStackTrace();
} finally {
cursor.close();
}
return list;
}

3.使用到的实体类

private int progress; //上传进度
private String timeStamps; //时间戳
private int flag; //上传标志 0-正常 1--网络错误 2--超时(除了0以为均为上传失败标识)

}
