Question

I have a project which shows list of blood donors using place search, i want to insert a call button in that list view for each user, i have no idea how to add it, Can you please help me with this? Screenshot 1: Screenshot 2: Each detail of the blood donor like name , blood group and phone are stored in each field in the server. "bld_phn" is the id of text view that shows phone number."phone" is the array string

code:

public class blood extends Activity {

    AsyncHttpClient client;
    JSONArray jarray;
    JSONObject jobject;
    RequestParams params;
    ListView lv;
    EditText enter;
    Button done;
    Button call;
    ArrayList<String> place;
    ArrayList<String>incharge;
    ArrayList<String>email;
    ArrayList<String>phone;
    ArrayList<String>reg;
    ArrayList<String>Bld;
    String temp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.blood);
        //prof=(EditText)findViewById(R.id.userProfile);
        client = new AsyncHttpClient();
        params = new RequestParams();
        //  submit=(Button)findViewById(R.id.submit);
        lv = (ListView) findViewById(R.id.List_all_blood);
        enter=(EditText)findViewById(R.id.enter_bld);

        done=(Button)findViewById(R.id.enter_blood);
        place = new ArrayList<String>();
        incharge = new ArrayList<String>();
        email = new ArrayList<String>();
        phone = new ArrayList<String>();
        reg = new ArrayList<String>();
        Bld = new ArrayList<String>();
        // final RelativeLayout rl = (RelativeLayout) findViewById(R.id.rl2);

//        findViewById(R.id.rl1).setOnClickListener(new View.OnClickListener() {
//
//            @Override
//            public void onClick(View v) {
//                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
//                imm.hideSoftInputFromWindow(rl.getWindowToken(), 0);
//
//            }
//        });

Use a recycler view because its easy and advanced , add a btn in list item , setonclick for that btn , on click add a call intent — Vinay Sasalatti, Apr 12 '18 at 11:31

For call button in listview you can add call button icon in listview's row file like below:-

    <Button
        android:id="@+id/buttonCall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Call" />

Then in activity, you can write below code in on click of call button to call functionality in android:-

Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("phone number"));
    startActivity(callIntent);

phone number in above code is a string var in which you can add number which you want to call.

I hope it will help you.

Me created a button in list row xml but i cant declare the button on .java file. how to set onclick in java for the button in listrow – Azhar Saeed Apr 12 '18 at 15:27
Sorry @AzharSaeed for late response.Yes,If you not declare the button in .java file not a problem.you can directly call button using function means put onclick on button in .xml file and create onclick method in .java and write your code inside that. – Janvi Vyas Apr 14 '18 at 04:37
use **android:onClick** of button like :- **android:onClick="Your function name"** – Janvi Vyas Apr 14 '18 at 04:40
Please @AzharSaeed use this and if you have any query let me know. – Janvi Vyas Apr 14 '18 at 04:43
Thankyou :) But me used this code in java file because i have a base adapter in that code convertView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { // do stuff here } }); – Azhar Saeed Apr 20 '18 at 11:53
