FIle API - Phonegap？

Question

任何人都可以解释如何使用Android的Phonegap File API列出页面上的文件文件夹吗？

.mp3如果可能的话,我想列出所有文件,但是已经阅读了所有的phonegap文档(http://docs.phonegap.com/en/1.0.0/phonegap_file_file.md.html)并且根本无法解决它!

它在@ $$中有点痛苦但可行.从这段代码开始:

document.addEventListener("deviceready", onDeviceReady, false);

// PhoneGap is ready
//
function onDeviceReady() {
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);
}

function onFileSystemSuccess(fileSystem) {
    fileSystem.root.getDirectory("Music", {create: false, exclusive: false}, getDirSuccess, fail);
}

function getDirSuccess(dirEntry) {
    // Get a directory reader
    var directoryReader = dirEntry.createReader();

    // Get a list of all the entries in the directory
    directoryReader.readEntries(readerSuccess,fail);
}

function readerSuccess(entries) {
    var i;
    for (i=0; i<entries.length; i++) {
        // Assuming everything in the Music directory is an mp3, go nuts
        // otherwise check entries[i].name to see if it ends with .mp3
    }
}

我正在IDE之外编写所有这些示例代码,因此可能存在错误但是应该让你继续.
