通过camera + gallery android上传文件到html

　　今天做项目的时候遇到一个问题：当html通过js调用input of type file时候，希望android手机的选择器可以同时出现“相机”和“图片”等，但通过下面代码

Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
((Activity) mContext).startActivityForResult(Intent.createChooser(i, "Image Choser"), 1);

只显示了“图片”，“文件管理器”等，就是没有“相机”！！！于是google了下找到类下面的方法

final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File externalDataDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
File cameraDataDir = new File(externalDataDir.getAbsolutePath()+File.separator+"browser-photos");
cameraDataDir.mkdirs();
String mCameraFilePath = cameraDataDir.getAbsolutePath()+File.separator+System.currentTimeMillis()+".jpg";
imageUri = Uri.fromFile(new File(mCameraFilePath));

final PackageManager packageManager = getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for(ResolveInfo res : listCam) {
   final String packageName = res.activityInfo.packageName;
   final Intent intent = new Intent(captureIntent);
   intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
   intent.setPackage(packageName);
   intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
   cameraIntents.add(intent);
}

mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");               
Intent chooserIntent = Intent.createChooser(i,"Image Chooser");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[]{}));
MainActivity.this.startActivityForResult(chooserIntent, FILECHOOSER_RESULTCODE);

简单运行下，perfect完美！！！

　　简单小结：通过上面的代码其实可以添加多种你想要的类型应用不止仅限于“相机”的。
