Android-將目前 圖片 傳至下一個 頁面 ( The image pass to next activity by intent )

相信各位也有跟我一樣的問題
那就是如何將圖片送至下一個頁面
網路上的資訊似乎都轉成陣列傳送
但傳送的容量又會受到限制
這似乎已經成為大家都痛

目前的作法僅供參考

A Activity

try {
          
   Bitmap bitmap = drawableToBitmap(imageView.getDrawable());
   File file = new File(getCacheDir(),"MyImage");
   FileOutputStream fileOutStream = new FileOutputStream(file);
   bitmap.compress(Bitmap.CompressFormat.PNG, 100, fileOutStream);

   Intent intent = new Intent();  
   intent.setClass(MainActivity.this, BActivity.class);
   intent.putExtra("image", Uri.fromFile(file) );
   startActivity(intent);
catch (FileNotFoundException e) {

   e.printStackTrace();
}

public static Bitmap drawableToBitmap(Drawable drawable) {  
    
  int w = drawable.getIntrinsicWidth();  
  int h = drawable.getIntrinsicHeight();  

    
  Bitmap.Config config = drawable.getOpacity() != PixelFormat.OPAQUE ? Bitmap.Config.ARGB_8888  
        : Bitmap.Config.RGB_565;  
     
  Bitmap bitmap = Bitmap.createBitmap(w, h, config);  
      
  Canvas canvas = new Canvas(bitmap);  
  drawable.setBounds(0, 0, w, h);  
     
  drawable.draw(canvas);  
  return bitmap;  
}

B Activity

ImageView imageView = (ImageView) findViewById(R.id.imageView1);
Uri uri = getIntent().getParcelableExtra("MyImage");
imageView.setImageURI(uri);
