Question

我有一个问题,即从安乐文的书库中提取照片,因为从来没有使用<条码>代谢()。

这是我所写的法典(从零碎块而不是一种活动):

Intent galleryIntent = new Intent(Intent.ACTION_PICK,  android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
getActivity().startActivityForResult(galleryIntent, PICK_IMAGE);

顺便说一句,我已经界定了“<>代谢”(),但从未启动过:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d(TAG, "onActivityResult"); // not printed
}

任何想法对此有什么错误?

感谢!

Answer 1

若要有<条码>活性效果(),请将<条码>的零散版本改为<条码>活性效果(,而不是活动页数。因此,在您的碎片代码中,替换

getActivity().startActivityForResult(galleryIntent, PICK_IMAGE);

iii

startActivityForResult(galleryIntent, PICK_IMAGE);

Answer 2

该法典载有:

Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
getActivity().startActivityForResult(galleryIntent, PICK_IMAGE);

在职者必须参与包含分裂性的活动。从那里,你可以把碎片的任何方法,而不是碎片。

MyFragment myFragment = (MyFragment) getSupportFragmentManager().findFragmentById(R.id.fragment);
myFragment .onCameraResult(requestCode, resultCode, intent);

页: 1

Answer 3

Try this Snippet :

    Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null);
    intent.setType("image/*");
    intent.putExtra("return-data", true);
    startActivityForResult(intent, 1);


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

        case 1:
            if(requestCode == 1 && data != null && data.getData() != null){
                Uri _uri = data.getData();

                if (_uri != null) {
                    Cursor cursor = getContentResolver().query(_uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
                    cursor.moveToFirst();
                    final String imageFilePath = cursor.getString(0);
                    File photos= new File(imageFilePath);
                    imageView.setImageBitmap(bitmap);
                    cursor.close();
                }
            }
            super.onActivityResult(requestCode, resultCode, data);
        }
    }
