Two ways to achieve it.
1) Need to start the dialer via code, without user interaction.
You need Action_Dial
,
use below code it will open Dialer with number specified
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:0123456789"));
startActivity(intent);
The 'tel:' prefix is required, otherwhise the following exception will be thrown: java.lang.IllegalStateException: Could not execute method of the activity.
Action_Dial doesn't require any permission.
If you want to initiate the call directly without user's interaction , You can use action Intent.ACTION_CALL
. In this case, you must add the following permission in your AndroidManifest.xml:
<uses-permission android:name="android.permission.CALL_PHONE" />
2) Need user to click on Phone_Number string and start the call.
android:autoLink="phone"
You need to use TextView with below property.
android:autoLink="phone" android:linksClickable="true" a textView property
You don't need to use intent or to get permission via this way.
