I want to transfer the image from one activity to another

Question

I have to transfer the image from one activity to another. In first activity the user selects the image out of several images from scroll view and that image has to be displayed in the imageview of next activity. Help required.

Answer 1

In your first Activity

Convert ImageView to Bitmap

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

    Intent intent = new Intent(this, NewActivity.class);
    intent.putExtra("BitmapImage", bitmap);

In second Activity

     Bitmap bitmap = (Bitmap) intent.getParcelableExtra("BitmapImage");

Then display bitmap in ImageView.

Note: this is not recommended. Should actually save the image somewhere and pass the path instead and retrieve from second activity.

Answer 2

you can pass it as a byte array and build the bitmap for display in the next activity. For instance:

In your first activity:

Intent i = new Intent(this, NextActivity.class);
Bitmap b; // your bitmap
ByteArrayOutputStream bs = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.PNG, 50, bs);
i.putExtra("byteArray", bs.toByteArray());
startActivity(i);

In your second activity

if(getIntent().hasExtra("byteArray")) {
    ImageView previewThumbnail = new ImageView(this);
    Bitmap b = BitmapFactory.decodeByteArray(
        getIntent().getByteArrayExtra("byteArray"),0,getIntent().getByteArrayExtra("byteArray").length);        
    previewThumbnail.setImageBitmap(b);
}

Answer 3

You can do this with many way. simple is with intent. but it may hang your device and it also give you out of memory Exception in many device like Galaxy S3.

so i ll give you very simple way see below.

you can create static variable in one class like :

public class ABC{

public static Bitmap PHOTO = null;

}

now when you get bitmap from gallery or any other way then you have to save bitmap in this PHOTO variable.(this is possible in only onActivityResult, am i right?)

if you get photo from camera then code is.

Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_PIC_REQUEST);

and,

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {

            switch (requestCode) {
                case CAMERA_PIC_REQUEST:
                    Bitmap b = (Bitmap) data.getExtras().get("data");
                    if (b != null) {
                        ABC.PHOTO = b;
                    }
                    break;
}
}

and use this PHOTO variable in any other Activity.

you can use this same way when pick photo from gallery.

hi this is edited ans.

this is just sample example of grid view. here you get idea about how pass image from one activity to another.

this is your main Activity class:

this is extra class: if you have bitmap then use this way:

package com.GridViewDemo;

import android.graphics.Bitmap;

public class test {

    public static Bitmap PHOTO = null;

}

i comment in code so, check it and if you have query then comment below this ans.

Answer 4

in first Activity first Make Sure you instantiate the bitmap at the top like Bitmap bitmap;

and then use this :- in the first Activity

ByteArrayOutputStream bs = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, bs);
byte[] byteArray = bs.toByteArray();
intent.putExtra("PICTURE", byteArray);
startActivity(intent);

and in the second activity:-

byte[] byteArray = extras.getByteArray("PICTURE");
bitmap = BitmapFactory.decodeByteArray(byteArray,0,byteArray.length);
imgViewResult.setImageBitmap(bitmap);

Answer 5

You can pass the URI of the Image to next Activity.

the URI which you get from onActivityResult()

and in onCreate() of the next Activity.

Decode the Bitmap again and set it to ImageView

Answer 6

See this post.

Use putExtra in first activity when you start second Activity. And in second Activity use getExtra() as follow:

In First Activity

Intent intent = new Intent(Activity1.this,Activity2.class);
intent.putExtra("bmp",selectedImage);
startActivity(intent);

In Second Activity

Bitmap bmp = this.getIntent().getParcelableExtra("bmp");

Answer 7

将您的图像转换为base64字符串格式并将其传递给下一个活动，然后再次将其解码为位图。

Answer 8

In first Activity :

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK){
        Intent showImageIntent = new Intent(this, ShowCameraPicture.class);
        showImageIntent.fillIn(data,Intent.FILL_IN_DATA);
        startActivity(showImageIntent);
    }
}

In second Activity :

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Bundle bundle = getIntent().getExtras();
    if(bundle!=null){
        Bitmap image = (Bitmap)bundle.get("data");
        //do whatever you need to do with the bitmap here ...
    }       
}

First Activity:

Intent intent = new Intent(CurrentActivity, secondActivity.class);

intent.putExtra("resId", R.drawable.your image);
startActivity(intent);

Then your Target Activity:

Bundle bundle = getIntent().getExtras();

if(bundle!=null){
    int image = bundle.getInt("resId");
    ImageId.setImageResource(image);
}
