一、Activity 生命周期

二、Fragment 生命周期

三、对比图

四、测试代码

[java]

import android.util.Log;

import android.view.LayoutInflater;

import android.view.ViewGroup;

import android.widget.ArrayAdapter;

import android.widget.ListView;

/**

* Demonstration of using ListFragment to show a list of items

* from a canned array.

*/

public class FragmentListArray extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

Log.e(HJJ, Activity &&&& onCreate...);

// Create the list fragment and add it as our sole content.

}

@Override

}

@Override

}

@Override

}

@Override

}

@Override

}

}

}
