1.使用SharePreferences存取数据：

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        SharedPreferences pref=PreferenceManager.getDefaultSharedPreferences(MainActivity.this);
        //方法2：SharedPreferences //pref=getSharedPreferences("mypref",MODE_PRIVATE);
        Editor editor=pref.edit();
        editor.putString("name", "王二");
        editor.putBoolean("default", true);
        editor.putInt("age", 30);
        editor.putLong("time", System.currentTimeMillis());
        editor.commit();//提交
        //System.out.println(pref.getInt("age", 0));
    }
}
