android中关于Activity生命周期的方法只有两个 onCreate，onResume

public class BolgDetailActivity extends SuperActivity implements OnClickListener{

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_news_detail);
    getWindow().setBackgroundDrawable(null);

    initView();
}
protected void onResume() {
    super.onResume();
    Intent intent = this.getIntent(); 
    item = (BlogItem) intent.getSerializableExtra("item");
    if ( item!=null ) {
        title.setText(item.getTitle());
        url = PATH + item.getId();
        loadBolgDetailInfo(url);
    }

onCreate创建，onResume从后台调入前台恢复运行
