我已经在谷歌上搜索了很长一段时间......但我仍然找不到我的问题的真正答案。问题是我需要一种方法让我的用户在按下 type="file" 的输入元素后能够选择从画廊或直接从相机上传文件。因此,如果那里有任何好的样品,请告诉我,或者如果您有样品可以让我看一下。
提前致谢!
public void attachFileInput() {
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);
}
This method will be in your JSInterface. Call it as follows:
$(".file").live('click', function() {
mySJInterface.attachFileInput();
});
Hope this helps.
我正在创建一个使用带有android webview的输入标签上传文件的程序。顺便说一句,我不是安卓应用程序员。
请看一下这些参考资料:Android webview、openfilechooser 终止和http://www.cnblogs.com/sipher/archive/2012/09/05/2672361.html。
脚步:
使用输入文件请求制作菜单以捕获照片 - Android webview,openfilechooser 终止。
但是图片没有发送到服务器并修改了 imageUri 值Environment.getExternalStoragePublicDirectory
,如此处所示 - http://www.cnblogs.com/sipher/archive/2012/09/05/2672361.html。
所以我需要在 Manifest 中添加权限 WRITE_EXTERNAL_STORAGE。
webView.setWebChromeClient(new WebChromeClient(){
@SuppressWarnings("unused")
public void openFileChooser(ValueCallback<Uri> uploadMsg){
this.openFileChooser(uploadMsg, "");
}
@SuppressWarnings("unused")
public void openFileChooser(ValueCallback<Uri> uploadMsg, String AcceptType, String capture) {
this.openFileChooser(uploadMsg, "");
}
@SuppressWarnings("unused")
public void openFileChooser(ValueCallback<Uri> uploadMsg, String AcceptType) {
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);
}
});
webView.getSettings().setDomStorageEnabled(true);
webView.loadUrl("..............");
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setWebViewClient(new WebViewClientClass());}
现在。我可以上传带有输入标签的相机拍摄的照片。
