title: More than one contentDescription for a button
body: <p>In my <code>activity</code> I have a method that reads the <code>contentDescriptio</code>n of a button and get the phone number and calls it.</p>
  
  <p>I have  a list of all departments in the company. But if for the same department we have more than one number what should I do. How to add more than one <code>contentDescription</code> for a button to pop a dialog that allows the user to choose between which number should he call.</p>
  
  <pre><code>public class ContactUs extends AppCompatActivity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_contact_us);
  
      ImageView back = (ImageView) findViewById(R.id.back);
      back.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              Intent i = new Intent(ContactUs.this , Introduction.class);
              startActivity(i);
              overridePendingTransition(R.animator.slide_in, R.animator.slide_out);
  
          }
      });
  }
  
  public void onClickCall(View view) {
  
      final String phoneNumber = view.getContentDescription().toString().trim();
  
      DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
          @Override
          public void onClick(DialogInterface dialog, int which) {
              switch (which){
                  case DialogInterface.BUTTON_POSITIVE:
                      //Yes button clicked
                      Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel://" + phoneNumber));
                      startActivity(intent);

                      break;
              }
          }
      };
      AlertDialog.Builder builder = new AlertDialog.Builder(this);
      builder.setMessage("Test Alert").setPositiveButton("Yes", dialogClickListener)
              .setNegativeButton("No", dialogClickListener).show();
