只需要重新

onSaveInstanceState方法，在其里面记住我们要记录的参数

package com.exmple.activity;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {

	private TextView text;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		text = (TextView) findViewById(R.id.text);

		if (savedInstanceState != null) {
			String a=savedInstanceState.getString("aa");
			text.setText(a);
		}

	}

	@Override
	protected void onSaveInstanceState(Bundle outState) {
		// TODO Auto-generated method stub
		super.onSaveInstanceState(outState);
		outState.putString("aa", "hhhhhh");
	}

	@Override
	protected void onDestroy() {
		Log.d("TAG","=============ondestoy");
		super.onDestroy();
		
	}

}
