我想在相对布局中膨胀相对布局.但是它只是膨胀一次之后它没有膨胀请帮我解决我的代码中的问题.

活动代码

LayoutInflater inflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);relativeLayout main = (relativeLayout)findVIEwByID(R.ID.passenger_details_layout);        for(int i=0;i<9;i++){                       VIEw vIEw = getLayoutInflater().inflate(R.layout.passenger_details_layout, main,false);            main.addVIEw(vIEw);        }

在@Ritaban建议并帮助我做了我所做的

活动代码：

LayoutInflater inflater;    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        super.onCreate(savedInstanceState);        requestwindowFeature(Window.FEATURE_NO_Title);        setContentVIEw(R.layout.activity_itineary_page);        inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);        /*         * LayoutInflater inflater = (LayoutInflater) getBaseContext()         * .getSystemService(Context.LAYOUT_INFLATER_SERVICE);         */        linearLayout main = (linearLayout) findVIEwByID(R.ID.main_passenger_details_layout);        for (int i = 0; i < 2; i++) {            inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);            relativeLayout layout = (relativeLayout) inflater.inflate(                    R.layout.passenger_details_layout, main, false);            main.addVIEw(layout, i);        }        relativeLayout lay = (relativeLayout) findVIEwByID(R.ID.thingstoshowbelow);        relativeLayout.LayoutParams params = (androID.Widget.relativeLayout.LayoutParams) lay                .getLayoutParams();        params.addRule(relativeLayout.BELOW, R.ID.main_passenger_details_layout);        lay.setLayoutParams(params);        lay.setVisibility(VIEw.VISIBLE);    }

解决方法:

使用线性布局作为父视图并给出androID：orIEntation =“vertical”.相对布局是一种布局,其中子项的位置相对于彼此或父项描述.如果要使用相对布局,则必须使用addrule属性,否则将覆盖前一个子项的所有子项.

例如：

<linearlayout            androID:ID="@+ID/passenger_details_layout"            androID:layout_wIDth="fill_parent"            androID:layout_height="wrap_content"            androID:layout_below="@+ID/travel_itin_header"            androID:layout_margintop="2dp"            androID:gravity="center_vertical"            androID:orIEntation = "vertical" >        </linearlayout>

在活动中：

  LayoutInflater inflater = (LayoutInflater)getBaseContext()                                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);           linearLayout main =(linearLayout)findVIEwByID(R.ID.passenger_details_layout);                  for(int i=0;i<9;i++){                   VIEw vIEw = inflater.inflate(R.layout.passenger_details_layout, null);        main.addVIEw(vIEw);    }
