问在Android中如何使用intent打开系统内置的图库应用程序？

EN

 private int PICK_IMAGE_REQUEST = 1;

tvGallery.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {

                    // Always show the chooser (if there are multiple options available)
                    startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);


                }
