android 圖片大小 視頻時長，視頻第一貞圖片

今天記錄一下獲取本地視頻時長的方法

/**
 * 獲取本地視頻的時長
 *
 * @param Videopath
 * @return
 */
public static long getPathLoang(String Videopath) {
    long time = 0;
    MediaPlayer meidaPlayer = new MediaPlayer();
    try {
        meidaPlayer.setDataSource(Videopath);
        meidaPlayer.prepare();
        time = meidaPlayer.getDuration() / 1000;
    } catch (IOException e) {
        e.printStackTrace();
    }
    return time;
}

獲取視頻第一楨圖片

/**
 * 獲取視頻的第一幀
 *
 * @param path
 * @return
 */
public static Bitmap getVideoThumb(String path) {
    MediaMetadataRetriever media = new MediaMetadataRetriever();
    media.setDataSource(path);
    return media.getFrameAtTime();

}

獲取本地圖片的大小

public static String bytes2kb(long bytes){
    BigDecimal fileSize = new BigDecimal(bytes);
    BigDecimal megabyte = new BigDecimal(1024*1024);
    float returnFloat = fileSize.divide(megabyte, 2, BigDecimal.ROUND_UP).floatValue();
    if (returnFloat>1){
        return returnFloat+"MB";
    }
    BigDecimal kilobyte = new BigDecimal(1024);
    returnFloat=fileSize.divide(kilobyte,2,BigDecimal.ROUND_UP).floatValue();
    return returnFloat+"kb";
}

public String pathSize(String imgUrl){
    File file = new File(imgUrl);
    FileInputStream fis;
    long fileLen = 0;
    try {
        fis = new FileInputStream(file);
        fileLen=fis.available();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    Log.e("長度","s"+BitmapUtil.bytes2kb(fileLen));
}
