我的应用程序中有个人资料图片概念。用户可以选择从应用程序中的相机或图库上载图像，但问题是图像正在上载到某些设备，而不是全部。问题主要出在Android 8和9版本上。我几乎尝试了所有方法，但未能实现。请帮忙。
代码：
dialog = new Dialog(getActivity());
dialog.setContentView(R.layout.dialog_image_upload);
dialog.setCanceledOnTouchOutside(false);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
TextView txtTakePhoto = (TextView) dialog.findViewById(R.id.txtTakePhoto);
TextView txtPictureFromGallery = (TextView) dialog.findViewById(R.id.txtPictureFromGallery);
ImageView imgClose = (ImageView) dialog.findViewById(R.id.imgClose);
imgClose.setOnClickListener(this);
txtTakePhoto.setOnClickListener(this);
txtPictureFromGallery.setOnClickListener(this)
从相机拍摄照片的代码：
case R.id.txtTakePhoto:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
{
cameraIntent();
}
} else {
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.CAMERA)) {
Toast.makeText(getActivity(), "App requires Phone permission.\nPlease allow that in the device settings.", Toast.LENGTH_LONG).show();
}
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.CAMERA}, PHONE_PERMISSION_CODE);
}
} else {
cameraIntent();
}
break;
从画廊拍照的代码：
case R.id.txtPictureFromGallery:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
{
imageBrowse();
}
} else {
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)) {
Toast.makeText(getActivity(), "App requires Phone permission.\nPlease allow that in the device settings.", Toast.LENGTH_LONG).show();
}
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, PHONE_PERMISSION_CODE);
}
} else {
imageBrowse();
}
break;
待上传图片的代码：
private void cameraIntent() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
}
private void imageBrowse() {
Intent galleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, PICK_IMAGE_REQUEST);
}
//handling the image chooser activity result
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == PICK_IMAGE_REQUEST) {
onSelectFromGalleryResult(data);
} else if (requestCode == REQUEST_CAMERA) {
onCaptureImageResult(data);
}
}
//
if (requestCode == 2 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri DbsUri = data.getData();
fileDbs = FilePath.getPath(getActivity(), DbsUri);
File f1 = new File(fileDbs);
edtCertificatesValue.setText(f1.getName());
Log.e("tag", "filedbs" + fileDbs);
} else if (requestCode == 3 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri picUri = data.getData();
filePath = FilePath.getPath(getActivity(), picUri);
File f2 = new File(filePath);
edtIdentityDocumentValue.setText(f2.getName());
Log.e("tag", "filePath" + filePath + " " + f2.getName());
} else if (requestCode == 4 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri picUri = data.getData();
fileAddress = FilePath.getPath(getActivity(), picUri);
File f3 = new File(fileAddress);
edtProofOfAddressValue.setText(f3.getName());
Log.e("tag", "fileAddress" + fileAddress);
} else if (requestCode == 5 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri CvUri = data.getData();
fileCvPath = FilePath.getPath(getActivity(), CvUri);
File f4 = new File(fileCvPath);
edtCurriculumVitaeValue.setText(f4.getName());
Log.e("tag", "fileCvPath" + fileCvPath);
//
}
//
// } else

是的，您需要配置FileProvider。在您的应用清单中，将提供程序添加到您的应用中：
<application>
...
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.android.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"></meta-data>
</provider>
...
</application>
确保授权字符串与getUriForFile（Context，String，File）的第二个参数匹配。在提供程序定义的元数据部分中，您可以看到提供程序希望在专用资源文件res / xml / file_paths.xml中配置合格的路径。这是此特定示例所需的内容：
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="Android/data/com.example.package.name/files/Pictures" />
</paths>
