Question

我正试图在我的Fragment中将图像从图库设置为图像视图。使用下面给出的GallerUtil类选择图片。

profile_home.setOnClickListener(new View.OnClickListener()
 {
        @Override
        public void onClick(View v)
        {
            Intent gallery_Intent = new Intent(getActivity(), GalleryUtil.class);
            startActivityForResult(gallery_Intent, GALLERY_ACTIVITY_CODE);
        }
    });

GalleryUtil.class

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        try{
            //Pick Image From Gallery
            Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(i, RESULT_SELECT_IMAGE);
        }catch(Exception e){
            e.printStackTrace();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch(requestCode){
            case RESULT_SELECT_IMAGE:

                if (resultCode == Activity.RESULT_OK && data != null && data.getData() != null) {
                    try{
                        Uri selectedImage = data.getData();
                        String[] filePathColumn = {MediaStore.Images.Media.DATA };
                        Cursor cursor = getContentResolver().query(selectedImage,
                                filePathColumn, null, null, null);
                        cursor.moveToFirst();
                        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                        String picturePath = cursor.getString(columnIndex);
                        cursor.close();

                        //return Image Path to the Main Activity
                        Intent returnFromGalleryIntent = new Intent();
                        Log.d("pathhh",picturePath);

                        returnFromGalleryIntent.putExtra("picturePath",picturePath);
                        setResult(RESULT_OK,returnFromGalleryIntent);
                        finish();

此图片的路径未进入我的onActivityResult片段中。所以请帮我找一个解决方案

片段中的onActivityResult -

 @Override
@SuppressLint("NewApi")
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d("pathhh1","11");

    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == GALLERY_ACTIVITY_CODE) {
        Log.d("pathhh","12");

        if(resultCode == Activity.RESULT_OK){
            picturePath = data.getStringExtra("picturePath");
            Log.d("pathhh",picturePath);
            //perform Crop on the Image Selected from Gallery
            performCrop(picturePath);
        }
    }

    if (requestCode == RESULT_CROP ) {
        if(resultCode == Activity.RESULT_OK){
            Bundle extras = data.getExtras();
            selectedBitmap = extras.getParcelable("data");
            //selectedBitmap1=getRoundedCroppedBitmap(selectedBitmap, 50);
            CircleDrawable circle = new CircleDrawable(selectedBitmap,true);
            if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN)
                profile_home.setBackground(circle);
            else
                profile_home.setBackgroundDrawable(circle);

            // Set The Bitmap Data To ImageView
            // profile_img.setImageBitmap(selectedBitmap1);
            profile_home.setScaleType(ImageView.ScaleType.FIT_XY);
        }
    }

将此代码写入您放置片段的MainActivity中。

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
            for (Fragment fragment : getSupportFragmentManager().getFragments()) {
                //Write your fragment name instead of YourFragmentName
                if (fragment instanceof YourFragmentName) {
                    fragment.onActivityResult(requestCode, resultCode, data);
                }
            }
    }

setresult没有进入我片段的OnActivityResult的价值
