从另一个活动设置ImageView资源和TextView文本

Question

I have a list view in an activity and when a row is selected I want to show another activity that contains an ImageView and a TextView. How can I set the image and text from the first activity? I'm guessing for the text I can use an extra with the intent.

Answer 1

intent.putExtra("data", bitmap)
intent.putExtra("your_string", strName);

You can recieve bitmap from another activity like this

Intent intent = getIntent();
Bitmap bitmap = (Bitmap) intent.getParcelableExtra("data");

It costs a lot of memory and is also slow.

If you want to pass it inbetween activities, you can store it in a file. That's more efficient.

Answer 2

There are multiple ways to sending data between Activities

1. you can send image intent.putExtra("data", bitmap) and recieve it as @deniz suggested
2. you can use Serializable to send data
3. you can create Parcelable and send it to next Activity
4. create a static Bitmap and get it in another Activity but it is not a good approach and against OOP
