How to send image loaded volleyball to next operation
I am using volley
to load images and text in listview
in my activity. When I click the line, I pass the image and text to Details . In the detail information, I would like to convey only Image
one more action.
After researching S / O, I found some code that works:
BitmapDrawable bd = (BitmapDrawable) ((NetworkImageView) view.findViewById(R.id.img2))
.getDrawable();
Bitmap bitmapzoom=bd.getBitmap();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bd.getBitmap().compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] imgByte = baos.toByteArray();
Intent intent=new Intent(getApplicationContext(),ZoomImage.class);
intent.putExtra("image", imgByte);
startActivity(intent);
}
});
And in the next activity I get it like:
Bundle extras = getIntent().getExtras();
byte[] b = extras.getByteArray("image");
Bitmap bmp = BitmapFactory.decodeByteArray(b, 0, b.length);
BitmapDrawable background = new BitmapDrawable(bmp);
findViewById(R.id.img2).setBackgroundDrawable(background);
However, the image is placed as a background image ... I would like to put an image in my ImageView.
Not as a background like in the code above.
Currently setting the image to the ImageView was not successful. Any suggestions would be greatly appreciated.
layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000"
android:orientation="vertical"
tools:context="com.softtech.stevekamau.buyathome.ZoomImage">
<ImageView
android:id="@+id/back"
android:layout_width="60dp"
android:layout_height="60dp"
android:src="@drawable/back"/>
<RelativeLayout
android:id="@+id/root_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000">
<ImageView
android:id="@+id/img2"
android:layout_width="300dp"
android:layout_height="300dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:scaleType="matrix"
android:maxHeight="100dp"
android:maxWidth="50dp" />
</RelativeLayout>
</LinearLayout>
How it looks like a background:

EDIT: To set the actual image of the image using a bitmap, not a bitmap:
Bundle extras = getIntent().getExtras();
byte[] b = extras.getByteArray("image");
Bitmap bmp = BitmapFactory.decodeByteArray(b, 0, b.length);
findViewById(R.id.img2).setImageBitmap(bmp);
Gently walking past large images in between activities, it may not show the image in another activity. It is better to save it to internal or external memory and then get it for another activity.

get the url of the image and pass it through linking, later in the action you can use the Picasso library to load the screen below, this is the code you can look at.
private void setImageWithPicaso(String imageUrl) {
if (!(imageUrl == null)) {
Picasso.with(getActivity()).load(imageUrl).placeholder(R.drawable.placeholder_background).into(imageView, new Callback() {
@Override
public void onSuccess() {
spinner.setVisibility(View.GONE);
}
@Override
public void onError() {
spinner.setVisibility(View.GONE);
AppLog.showToastMessage(getActivity(), "Image loading failed!");
}
});
} else {
spinner.setVisibility(View.GONE);
AppLog.showToastMessage(getActivity(), "Image loading failed!");
}
}
Replacement:
findViewById(R.id.img2).setBackgroundDrawable(background);
for
findViewById(R.id.img2).setImageDrawable(background);
However, the image is placed as a background image. I would like to put an image in my ImageView. Not as a background like the code above.
I think I get where your confusion comes from. Not sure if you fully understand what an ImageView is. Your image is infact in your image, otherwise you will not see it.
