Write Contacts in Android

In questo esempio utilizziamo Intent per inserire un nuovo contratto tramite l’ App Contatti senza bisogno di autorizzazioni, utilizzando ContactsContract.RawContacts:

activity_main.xml
<?xml version=”1.0″ encoding=”utf-8″?>
<LinearLayout
xmlns:android=”http://schemas.android.com/apk/res/android&#8221;
android:layout_width=”match_parent”
android:layout_height=”match_parent”
android:gravity=”center”
android:orientation=”vertical”>



<Button
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:text=”Contacts Write”
android:id=”@+id/btn”/>
</LinearLayout>

MainActivity.java
package com.example.writeContacts.activities;

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import com.example.writeContacts.R;
import android.widget.*;
import android.view.*;
import android.content.*;
import android.provider.*;

public class MainActivity extends AppCompatActivity {

Button btn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


btn=findViewById(R.id.btn);

btn.setOnClickListener(new View.OnClickListener(){

@Override
public void onClick(View view){
Intent intent = new Intent(ContactsContract.Intents.Insert.ACTION);

   intent.setType(ContactsContract.RawContacts.CONTENT_TYPE);   

startActivity(intent);
  
  }
});
}

    }
