title: Android Phone number Calling Function in an Activity
body: <p>I am developing Android Application having ContactUs Page having Phone Number. I had given the Phone number in xml file as below:</p>
  
  <pre><code>&lt;TextView 
  android:layout_height="wrap_content" 
  android:textAppearance="?android:attr/textAppearanceSmall" 
  android:text="1-869-270-9099" 
  android:textSize="11sp"
  android:textColor="#104082"
  android:textStyle="normal"
  android:layout_width="wrap_content" 
  android:id="@+id/textView4" 
  android:layout_x="72dp" 
  android:layout_y="160dp"/&gt;
  </code></pre>
  
  <p>I had created the <code>AlertDialog</code> and when the phone number is clicked the alert <code>dialog</code> will be shown programatically as below:</p>
  
  <pre><code>   @Override
     protected Dialog onCreateDialog(int id) {
      switch (id) {
      case (R.id.textView4):
  
          Builder builder = new AlertDialog.Builder(this);
          builder.setMessage("Do you want to Call?");
          builder.setCancelable(false);
          builder.setPositiveButton("Call", new DialogInterface.OnClickListener() {
              public void onClick(DialogInterface dialog, int which) {
                 //Do Calling a Number
  
  
              }
          });
          builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
              public void onClick(DialogInterface dialog, int which) {
                      dialog.cancel();
              }
          });
          AlertDialog dialog = builder.create();
          dialog.show();
      }
      return super.onCreateDialog(id);
  }
         public void onClick(View v) {
  
      switch(v.getId()){
      case (R.id.textView4):
  
          showDialog(R.id.textView4);
      break;
      }
  
  }
  </code></pre>
