public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
    {
        //Pega o item que foi selecionado.
        ItemPromo item = adapterListView.getItem(arg2);
        //Demostração
        //Toast.makeText(this,item.getTexto(), Toast.LENGTH_LONG).show();
        Intent intent = new Intent(this,Promocao.class);
        intent.putExtra("valor1",item.getTexto());
        intent.putExtra("valor2",item.getIconeRid());
        startActivity(intent);
    }

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

        else if(bundle.containsKey("valor2")){
            int v = bundle.getInt("valor2");
            imgTeste.setImageAlpha(v);

Example: 

Bundle extras = new Bundle();
extras.putParcelable("Bitmap", bmp);
intent.putExtras(extras);
startActivity(intent);

And in the second Activity: 

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

  • If bitmap is a file or resource and you have its ID or file path, it’s always better to pass it than the bitmap itself. What saves a good amount of memory resources and can even prevent problems in the App, since the maximum size of an Intent is around 1mb.

  • You are right, when the application allows the image to be recovered by a URL or the path is worth using this resource and pass a String. As to that of 1MB did not know, thank you for the information.
