27. Разработка приложений для ОС Android. SharedPreferences

1) Добавляем EditText
2) В Main.java добавляем код:

package com.example.data;

import android.os.Bundle;
import android.app.Activity;
import android.content.SharedPreferences;
import android.view.Menu;
import android.widget.EditText;

public class Main extends Activity {
    
    private EditText edit1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        edit1 = (EditText) findViewById(R.id.editText1);
        SharedPreferences save = getSharedPreferences("SAVE", 0);
        edit1.setText(save.getString("text", ""));
    }
    
    @Override
    protected void onStop() {
        // TODO Auto-generated method stub
        super.onStop();
        SharedPreferences save = getSharedPreferences("SAVE", 0);
        SharedPreferences.Editor editor = save.edit();
        editor.putString("text", edit1.getText().toString());
        editor.commit();
    }

    @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;
    }

}
