从相机碎片中拍照
从相机碎片中拍照
提问于 2013-03-14 19:40:14
在我的Fragment中，我尝试从相机拍照，但是我的Fragment的onActivityResult没有被调用。拍照后，这个Fragment没有显示，正在切换到我的第一个Fragment。有没有其他方法可以捕获Fragment中的照片，或者我做错了什么？
下面是我当前的代码：
public void takePhoto() {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
PhotosListFragment.this.startActivityForResult(intent, 100);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 100:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getActivity().getContentResolver().notifyChange(selectedImage, null);
ContentResolver cr = getActivity().getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
viewHolder.imageView.setImageBitmap(bitmap);
Toast.makeText(getActivity(), selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(getActivity(), "Failed to load", Toast.LENGTH_SHORT)
.show();
Log.e("Camera", e.toString());
}
}
}

我试过你的代码，它运行得很好，伙计。我变了
PhotosListFragment.this.startActivityForResult(intent, 100);至
getActivity().startActivityForResult(intent, 100);在拍摄完照片后，返回到相同的活动。
我想你的两个片段都在同一活动中。
如果是这种情况，我建议您创建一个新的活动，并将新的片段放入其中。

希望这能对你有所帮助：
public class CameraImage extends Fragment {
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 1888;
Button button;
ImageView imageView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.camera_image,
container, false);
button = (Button) rootView.findViewById(R.id.button);
imageView = (ImageView) rootView.findViewById(R.id.imageview);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent,
CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
});
return rootView;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == Activity.RESULT_OK) {
Bitmap bmp = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
// convert byte array to Bitmap
Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0,
byteArray.length);
imageView.setImageBitmap(bitmap);
}
}
}

对于Fragment，这是最简单的解决方案：
cameraIamgeView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent cameraIntent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
getActivity().startActivityFromFragment(PlaceOrderFragment.this, cameraIntent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
});
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
// super.onActivityResult(requestCode, resultCode, data);
try {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == Activity.RESULT_OK && data != null) {
Bitmap bmp = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
/*
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
// convert byte array to Bitmap
Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0,
byteArray.length);
*/
cameraIamgeView.setImageBitmap(bmp);
}
}
}catch(Exception e){
Toast.makeText(this.getActivity(), e+"Something went wrong", Toast.LENGTH_LONG).show();
}
