获取 ImageView 的图像并将其发送到具有 Intent 的活动 [英] get ImageView's image and send it to an activity with Intent

问题描述

我的应用中有许多产品的网格.当用户选择网格中的项目之一时，我将启动一个新活动作为 DIALOG 框并显示项目的名称、数量和图像.但是我无法动态发送图像源.

I have a grid of many products in my app. when the user selects one of the item in the grid, I am starting a new activity as DIALOG box and display the item's name,quantity and image. But I cannot send the image source dynamically.

这是我的代码

gridView.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,int position, long id) {
            //Toast.makeText(getApplicationContext(),((TextView) v.findViewById(R.id.grid_item_label)).getText(), Toast.LENGTH_SHORT).show();
            Intent item_intent = new Intent(MainActivity.this, Item.class);
            item_intent.putExtra("name",((TextView) v.findViewById(R.id.grid_item_label)).getText());
            item_intent.putExtra("quantity",((TextView) v.findViewById(R.id.grid_item_quantity)).getText());

            //my problem is here***************************************************
            ImageView my_image =  findViewById(R.id.grid_item_image).getDrawable();
            item_intent.putExtra("image",my_image.getXXXXX());
            //*********************************************************************
            MainActivity.this.startActivity(item_intent);

        }
    });

我应该使用什么来从 ImageView 获取图像源?

What should I use to get the image source from ImageView?

推荐答案

Use Bundle like

Use Bundle like

imageView.buildDrawingCache();
Bitmap image= imageView.getDrawingCache();

 Bundle extras = new Bundle();
extras.putParcelable("imagebitmap", image);
intent.putExtras(extras);
startActivity(intent);


Bundle extras = getIntent().getExtras();
Bitmap bmp = (Bitmap) extras.getParcelable("imagebitmap");

image.setImageBitmap(bmp );
