Local Data Storage Android

private static String logtag ="logtag";
private static String NAME = "name";
private SharedPreferences saveName;

logtag = untuk debuging dan melihat log yang di jalankan di locat.
NAME = nama yang nantinya menjadi tag XML yang mengindikasikan nilai yang akan di isi, seperti kalau kita membuat value di values/strings.xml
saveName = variable sharepreferences.

setalah itu buat variable saveName diberi nilai objek getPreferences(MODE). seperti berikut

saveName = getPreferences(MODE_PRIVATE);

kemudian buat method <code>saving()</code> digunakan untuk menyimpan inputan dan method <code>refreshing()</code> seperti berikut :

public void saving(View v){
 Log.i(logtag, "checked");
 SharedPreferences.Editor editor = saveName.edit();
 String prefValue = uiGet.getText(this, R.id.nameIn);
 editor.putString(NAME, prefValue);
 editor.commit();
 uiGet.displayText(this, R.id.textView2, "Saved");
 }

public void refreshing(View v){
 Log.i(logtag, "refreshed");
 String value = saveName.getString(NAME,"Not Found");
 uiGet.displayText(this, R.id.textView2, value);
 
 }

Log.i = digunakan untuk menampilkan text pada logcat untuk debugging
uiGet = class yang sebelumnya kita buat

sehingga seluruh sorucecode di MainActivity.java adalah berikut:

package com.example.shareprefmulti;

import com.example.shareprefmulti.UiGet.uiGet;
import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

public class MainActivity extends Activity {
 
 private static String logtag ="logtag";
 private static String NAME = "name";
 private SharedPreferences saveName;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

 saveName = getPreferences(MODE_PRIVATE);
 //saveName = getSharedPreferences(NAME, MODE_PRIVATE);
 }
 
 public void saving(View v){
 Log.i(logtag, "checked");
 SharedPreferences.Editor editor = saveName.edit();
 String prefValue = uiGet.getText(this, R.id.nameIn);
 editor.putString(NAME, prefValue);
 editor.commit();
 uiGet.displayText(this, R.id.textView2, "Saved");
 }
 
 public void refreshing(View v){
 Log.i(logtag, "refreshed");
 String value = saveName.getString(NAME,"Not Found");
 uiGet.displayText(this, R.id.textView2, value);
 
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {

 // Inflate the menu; this adds items to the action bar if it is present.
 getMenuInflater().inflate(R.menu.main, menu);
 return true;
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
 // Handle action bar item clicks here. The action bar will
 // automatically handle clicks on the Home/Up button, so long
 // as you specify a parent activity in AndroidManifest.xml.
 int id = item.getItemId();
 if (id == R.id.action_settings) {
 return true;
 }
 return super.onOptionsItemSelected(item);
 }
