- 안드로이드에서 SharedPreferences 와 PreferenceScreen을 활용하여, 내부적인 저장을 해보자.
- 보통 어플리케이션 설정창을 이용할 때 많이 사용한다.

-Java 소스

public class Ex09_Preferences1Activity extends Activity implements
OnClickListener {
EditText text1;
EditText text2;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
text1 = (EditText) this.findViewById(R.id.edittext1);
text2 = (EditText) this.findViewById(R.id.edittext2);

SharedPreferences pref = getSharedPreferences("PrefTest", 0);
String name = pref.getString("Name", "Guest");// name을 못읽었을때 guest
int no = pref.getInt("No", 0); // 저장하기위한 인자값받기

text1.setText(name);
text2.setText(no + "");

Button btn1 = (Button) findViewById(R.id.button1);
btn1.setOnClickListener(this);

}

@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();

SharedPreferences pref = getSharedPreferences("PrefTest", 0);
SharedPreferences.Editor edit = pref.edit();

edit.putString("Name", text1.getText().toString()); //저장된값가져오기
edit.putInt("No", Integer.parseInt(text2.getText().toString()));
edit.commit();
}

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(this, Setting.class); //PreferencesScreen 엑티비티
startActivity(intent);

}
}
--------------------------------------------------------------------------------------------------------
public class Setting extends PreferenceActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.layout.settings);
}
}
