Camera拍摄的照片或所选照片未显示在ImageView中。我正在使用以下代码：
private void attachFile() {
final CharSequence[] items = {"Camera", "Gallery", "Cancel"};
AlertDialog.Builder builder;
builder = new AlertDialog.Builder(mContext);
builder.setTitle("Add Image");
builder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
if(items[i].equals("Camera")) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
} else if (items[i].equals("Gallery")) {
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent,"Select Photo"), SELECT_FILE);
} else if (items[i].equals("Cancel")) {
dialogInterface.dismiss();
}
}
});
builder.show();
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == Activity.RESULT_OK) {
if (requestCode == REQUEST_CAMERA && data != null) {
Log.d(TAG, "onActivityResult: done take photo");
Uri mImageCaptureUri = data.getData();
imageView.setImageURI(mImageCaptureUri);
/*Bundle bundle = data.getExtras();
final Bitmap bitmap = (Bitmap) bundle.get("data");
mOnphotoSelectedListener.getImageBitmap(bitmap);*/
} else if (requestCode == SELECT_FILE) {
Uri selectImageUri = data.getData();
mOnphotoSelectedListener.getImagePath(selectImageUri);
//imageView.setImageURI(selectImageUri);
//Picasso.with(mContext).load(selectImageUri).into(imageView);
//Picasso.with(this).load(selectImageUri).into(imageView);
}
}
}
答案 0 :(得分：0)
在onActivityResult
if (requestCode == Activity.RESULT_OK) {
File user_dp;
if (requestCode == REQUEST_CAMERA && data != null) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File destination = new File(Environment.getExternalStorageDirectory(), System.currentTimeMillis() + ".jpg");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
user_dp = destination;
//update_profilepic is ImageView reference
Picasso.with(getContext()).load(user_dp).into(update_profilepic);
} else if (requestCode == SELECT_FILE) {
Bitmap bm = null;
if (data != null) {
try {
bm = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), data.getData());
} catch (IOException e) {
e.printStackTrace();
}
}
//ivImage is image reference
ivImage.setImageBitmap(bm);
}
}
}
答案 1 :(得分：0)
我在if语句的第一行中使用了requestCode而不是resultCode。

我有此代码，我希望它能为您正常工作 我为ImageProfile设置了onclick，然后给用户图片+裁剪 我希望它对你有用

int persmissonCheck = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.CAMERA);
if (persmissonCheck == PackageManager.PERMISSION_DENIED) {
