Android Load Full Image Recyclerview Cardview

Question

以下是我在附图中使用 php mysql 和 volley 库的 recyclerview。到目前为止，当单击显示的图像时，图像名称的 toast 就会出现。是否可以加载完整的图像点击而不是 toast 消息？提前谢谢你

主要活动

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        ImageTitleNameArrayListForClick = new ArrayList<>();

        ListOfdataAdapter = new ArrayList<>();

        recyclerView = (RecyclerView) findViewById(R.id.recyclerview1);

        recyclerView.setHasFixedSize(true);

        layoutManagerOfrecyclerView = new LinearLayoutManager(this);

        recyclerView.setLayoutManager(layoutManagerOfrecyclerView);

        JSON_HTTP_CALL();

        // Implementing Click Listener on RecyclerView.
        recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {

            GestureDetector gestureDetector = new GestureDetector(MainActivity.this, new GestureDetector.SimpleOnGestureListener() {

                @Override public boolean onSingleTapUp(MotionEvent motionEvent) {

                    return true;
                }

            });
            @Override
            public boolean onInterceptTouchEvent(RecyclerView Recyclerview, MotionEvent motionEvent) {

                view = Recyclerview.findChildViewUnder(motionEvent.getX(), motionEvent.getY());

                if(view != null && gestureDetector.onTouchEvent(motionEvent)) {

                    //Getting RecyclerView Clicked Item value.
                    RecyclerViewItemPosition = Recyclerview.getChildAdapterPosition(view);

                    // Showing RecyclerView Clicked Item value using Toast.
                    Toast.makeText(MainActivity.this, ImageTitleNameArrayListForClick.get(RecyclerViewItemPosition), Toast.LENGTH_LONG).show();
                }

                return false;
            }

            @Override
            public void onTouchEvent(RecyclerView Recyclerview, MotionEvent motionEvent) {

            }

            @Override
            public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

            }
        });

提取图像的完整路径并将其放入变量中，如下所示：

http://yourserver.com/path/to/your/image.jpg

然后将图像加载器库添加到您的项目中，例如 Glide 或 Picasso

然后您可以在任何需要的地方加载图像。比如加载alert dialog。
