StartActivity in Custom ListView Adapter

Question

I'm setting an onClick to my TextView called phone in my custom ListView . When the TextView is clicked, I would like for it to open up Android's Dial screen. I passed the Context of my Activity to my Custom Adapter Java Class but the app still keeps crashing every time I click on my TextView . The following code consists of the constructor as well as the last few methods in my Custom Adapter Java Class:

    public CustomAdapter(Context c,ArrayList<String>n,ArrayList<String>nums, ArrayList<String>e){
           context = c;
           phoneNumbers = nums;
           names = n;
           emails = e;
           inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

...

    public View getView(int position, View convertView, ViewGroup parent) {
    View view = convertView;

    if (view == null){
        view = inflater.inflate(R.layout.contacts_custom_row,null);
        TextView phone = (TextView)view.findViewById(R.id.customRowContactNumber);

        phone.setOnClickListener(this);
    }
    return view;
}

@Override
public void onClick(View v) {
    switch (v.getId()){
        case R.id.customRowContactNumber:{
            Intent i = new Intent(Intent.ACTION_DIAL);
            context.startActivity(i);//I passed the context to my constructor
            break;
        }
    }

}

Please let me know what I'm doing wrong, thank you. Here is the log cat error:

Answer 1

If you're sure here is where you want to start the activity you can just add

Intent i = new Intent(Intent.ACTION_DIAL);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

then start it as you were,

context.startActivity(i);

It looks like the context your passing isn't the context of an Activity which is why it's giving you the warning. If you're sure, you can do what @fixmycode suggested with changing the class declaration.

Answer 2

In your class declaration:

public CustomAdapter(Activity activity, ...){
    Activity myActivity = activity;
    ...
}

In your onClick method:

myActivity.startActivity(...);
