public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    public void onClick(View v) {        switch (v.getId()) {        case R.id.button1:            SharedPreferences sp = this.getSharedPreferences("myxml", Context.MODE_PRIVATE);            Editor editor = sp.edit();            editor.putString("name", "nanguabing");            editor.putInt("age", 20);            //持久化操作到存放裝置            editor.commit();            Toast.makeText(this, "寫入sp完成", 1).show();            break;        case R.id.button2:            SharedPreferences sp1 = this.getSharedPreferences("myxml", Context.MODE_PRIVATE);            String name = sp1.getString("name", "nobody");            int age = sp1.getInt("age", 0);            Toast.makeText(this, "name=" + name + ",age=" + age, 1).show();            break;        default:            break;        }    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.activity_main, menu);        return true;    }}
