有目的地传递视图 [英] Passing View with Intent

问题描述

我想通过我的 view 更新其他活动中的 view .这是我要传递 view 的代码.

I want to passing my viewto update my view in other activity. This is my code to passing view.

emp_photo_edit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                i.putExtra("container", (Serializable) viewDialog);
                ((EmployeeActivity)context).startActivityForResult(i, 2017);
            }
        });

然后我想在其他活动中更新视图

Then i want to update my view in other activity

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 2017 && resultCode == RESULT_OK && null != data) {
        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();
        View apa = (View) data.getSerializableExtra("content");
        //View dialog = View.inflate(getApplicationContext(),R.layout.dialog_employee_edit,null);
        ImageView imageView = (ImageView) apa.findViewById(R.id.emp_photo_edit);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
    }
}

但是显示异常.

推荐答案

传递给捆绑软件的参数应实现 Serializable 或 Parcelable 接口. LinearLayout 没有.最好的解决方案是将视图内的数据传递给Intent并将其应用于接收方 Activity

Arguments passed to the bundle should implement the Serializable or Parcelable interface. The LinearLayout doesn't. The best solution is to pass the data inside the view to the Intent and apply that to a view in the receiving Activity
