我没有从我从 WhatsApp 收到的 uri 的图像或视频中获取路径。
Uri 是这样的：content://com.whatsapp.provider.media/item/16695
来自图库、下载和其他的媒体都很好。
有谁知道怎么获取路径？这是我正在使用的代码：
public String getMediaPath(Context context, Uri uri) {
if (DEBUG)
Log.d(TAG + " File -",
"Authority: " + uri.getAuthority() +
", Fragment: " + uri.getFragment() +
", Port: " + uri.getPort() +
", Query: " + uri.getQuery() +
", Scheme: " + uri.getScheme() +
", Host: " + uri.getHost() +
", Segments: " + uri.getPathSegments().toString()
);
// DocumentProvider
if (DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri); …我想创建一个JSONObject像这样的：
[
{
id:01,
name:"John",
number:010
},
{
id:02,
name:"Mike",
number: 020
}
]
这是我的代码：
public void equipmentViewed(List<Equipment> equipmentSelected, final OnControlResponseListener listener, String description, Equipment equipment) throws JSONException {
wsAccessControl = WSAccessControl.getInstance();
EquipmentViewed equipmentViewed = new EquipmentViewed();
equipmentViewed.setEquipment(equipmentsCount(equipmentSelected));
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("", new JSONArray(equipmentViewed.getEquipment().toString()));
} catch (JSONException e) {
Log.e(TAG, "Failed to create json object. Cause: " + e.getMessage());
}
String url = Constants.PROVIDER_DOMAIN_URL + Constants.REQUEST_EQUIPMENT;
wsAccessControl.makeWSRequest(RequestType.POST, url, jsonObject, new Response.Listener<String>() {
@Override
public …我有下面的代码来压缩我想要的内容。
public class JCreateZIP {
private static final int BUFFER = 80000;
public int zip(List<String> _files, String zipFileName) {
try {
BufferedInputStream origin = null;
FileOutputStream dest = new FileOutputStream(zipFileName);
ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(
dest));
byte data[] = new byte[BUFFER];
for (int i = 0; i < _files.size(); i++) {
Log.v("Compress", "Adding: " + _files.get(i));
FileInputStream fi = new FileInputStream(_files.get(i));
origin = new BufferedInputStream(fi, BUFFER);
ZipEntry entry = new ZipEntry(_files.get(i).substring(_files.get(i).lastIndexOf(File.separator) + 1));
out.putNextEntry(entry);
int count;
while ((count = …
