Android:Get button clicked in custom listview

Question

I have used LazyAdapter for creating a custom listview. Now I require to use an image which can be clicked to dial a number. The error is coming in the onclick method of the image. StartActivity says "there is no such method in LazyAdapter". I am posting the code below.

public class LazyAdapter extends BaseAdapter {

private Activity activity;
private String[] data;
private String[] project;

Context con;

public LazyAdapter(Context con) {
    this.con = con;
}


public LazyAdapter(Activity a, String[] pic, String[] p) {
    activity = a;
    data = pic;
    project = p;
    inflater = (LayoutInflater) activity
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    imageLoader = new ImageLoader(activity.getApplicationContext());
}

public int getCount() {
    return data.length;
}

public Object getItem(int position) {
    return position;
}

public long getItemId(int position) {
    return position;
}

public View getView(final int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater) con
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View vi = convertView;

    if (convertView == null)
        vi = inflater.inflate(R.layout.item_result_page, null);



    ------more code----
    ImageView ivCall = (ImageView) vi.findViewById(R.id.imageViewIRCall);
    ivCall.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            String uri = "tel:9818222333";
             Intent intent = new Intent(Intent.ACTION_DIAL);
             intent.setData(Uri.parse(uri));
             startActivity(intent);
        }
    });

    return vi;
}

I have already refered this link but the error is there in startActivity. SO link

Answer 1

Simply you need to append context of activity while calling intent!

Within Onclick@

Use#

Intent intent = new Intent(Intent.ACTION_DIAL);
             intent.setData(Uri.parse(uri));
             activity.startActivity(intent);

Instead#

Intent intent = new Intent(Intent.ACTION_DIAL);
             intent.setData(Uri.parse(uri));
             startActivity(intent);

Additionally#

Use ViewHoder inside getView() method and set tag to button and get tag inside onClick to get correct position of view.

Answer 2

use

activity.startActivity(intent);

instead of

startActivity(intent);

and make sure you have permission for phone call in the AndroidManifest.xml

<uses-permission android:name="android.permission.CALL_PHONE"/>
