Passing Array of Strings to another activity to use with ion

Question

I have ListView and i uses ion library to load images in he rows of it, When i tap on any row i take the data on the row like TextView and display it in activity using Intent

Sender Activity

// Keys
public static String TITLE = "title";
public static String ARTICLE = "article";
public static String IMG = "img";


Intent passData = new Intent(getContext(), ArticleScreen.class);
       passData.putExtra(TITLE, tv.getText());
       passData.putExtra(ARTICLE, tv2.getText());
       getContext().startActivity(passData);

Receiver Activity

Bundle extras = getIntent().getExtras();

    if (extras != null) {

        title = extras.getString(NewsAdapter.TITLE);
        article = extras.getString(NewsAdapter.ARTICLE);

    }

Now I have different ImageView in every row in the ListView and i want to display that image in the activity with the text using ion library, So i have Array of String named thumbUrl contains the urls that i want to display in the row and activity.

Ion in Sender Activity

ImageView iv = (ImageView) v.findViewById(R.id.mThumb);

    Ion.with(getContext()).load(thumbUrl[position])
            .withBitmap()
            .placeholder(R.drawable.ic_settings_black_24dp)
            .error(R.drawable.ic_info_outline_black_24dp)
            .intoImageView(iv);

So i tried to send that thumbUrl Array using Bundle and Intent like this:

Bundle b = new Bundle();
       b.putStringArray(IMG, thumbUrl);

       Intent passData = new Intent(getContext(), ArticleScreen.class);
       passData.putExtra(TITLE, tv.getText());
       passData.putExtra(ARTICLE, tv2.getText());
       passData.putExtras(b);
       getContext().startActivity(passData);

and receive it like this:

Ion in Receiver Activity

private String[] img;

Bundle extras = getIntent().getExtras();

    if (extras != null) {

        title = extras.getString(NewsAdapter.TITLE);
        article = extras.getString(NewsAdapter.ARTICLE);
        img = extras.getStringArray(NewsAdapter.IMG);

    }

    ImageView iv = (ImageView) findViewById(R.id.articleImg);

    Ion.with(this).load(Arrays.toString(img))
            .withBitmap()
            .placeholder(R.drawable.ic_settings_black_24dp)
            .error(R.drawable.ic_info_outline_black_24dp)
            .intoImageView(iv);

But it's gives me that exception

 08-20 23:51:23.841  28725-28725/com.mEmoZz.App W/Bundle﹕ Key img expected String[] but value was a java.lang.Integer.  The default value <null> was returned.

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:699)

So what to do right now?

Sorry for that messy problem but am just a beginner and that's my first time to deal with apps like that.

Answer 1

You should pass the url of the image related to the row being clicked. DO NOT pass the whole array:

//In the Sender:
passData.putExtra(IMG, thumbUrl[position]);

//In the Receiver
String img = extras.getString(NewsAdapter.IMG);
