android初练三

android之传递图片

    //将主的页面中要传递的内容封装到intent(意图中去)
    public void onClick(View v)
    {
        Intent intent = new Intent(MainActivity.this,SecondActivity.class);
        Bundle bundle = new Bundle();

        Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drwable.lamp);
        bundle.putPracelable("bitmap",bitmap);
        intent.putExtras(bundle);
        startActivity(intent);
    }

    protected void onCreate(Bundle saveInstaceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
        ImageView =(ImageView)findViewById(R.id.imageView);
        Intent intent = getIntent();
        if(intent!=null)
        {
            Bitmap bitmap = intent.getPracelableExtra("bitmap");
            image.setImageBitmap(bitmap);
        }
    }

于是乎就实现将图片进行传递

注意在使用bundle传送数据时，不要用bundle传送大量的数据
