hi i have a code to save the contact in your database by shared preference here is my code

public class Main22Activity extends AppCompatActivity {
    EditText nameInput,phoneInput;
    TextView LargeText;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main22);
        nameInput = (EditText) findViewById(R.id.nameInput);
        phoneInput = (EditText) findViewById(R.id.phoneInput);

        LargeText = (TextView) findViewById(R.id.textView2);
    }

    public void saveInfo (View view){
        SharedPreferences sharedPref = getSharedPreferences("nameInfo" , Context.MODE_PRIVATE);
        SharedPreferences.Editor editor= sharedPref.edit();
        editor.putString("name", nameInput.getText().toString());
        editor.putString("phone", phoneInput.getText().toString());
        editor.apply();
        Toast.makeText(this, "Saved", Toast.LENGTH_LONG).show();
    }

    public void displayData(View view){
        SharedPreferences sharedPref = getSharedPreferences("nameInfo" , Context.MODE_PRIVATE);
        String name = sharedPref.getString("name", "");
        String ph = sharedPref.getString ("phone","");
        LargeText.setText(name + " " + ph);
    }
}
