在PageViewer的Andr​​oid的BaseAdapter类中调用片段 [英] Calling Fragment from inside the BaseAdapter class in PageViewer Android

问题描述

您好我是新来的Andr​​oid和我在我的项目中使用PageViewer显示选项卡刷卡和其他类似的东西。

我用4个标签和并用碎片为每个标签
现在我有哪个按钮是那里呼吁同一选项卡即另一片段列表的选项卡1，我需要更换相同选项卡上的片段。

我已经对所看到的链接栈的问题而说，使用广播听众在片段呼吁打击。我用它在我的片段类。

<$p$p><$c$c>http://stackoverflow.com/questions/22265378/how-to-call-a-fragment-from-baseadapter-class-android/22265433#22265433

我得到我需要在框架布局调用错误

，因为它采用了Android的id，如果我将其更改为@ + ID，然后提示错误

 ＆LT;的FrameLayout
                    机器人：ID =@机器人：ID / tabcontent
                    机器人：layout_width =0dp
                    机器人：layout_height =0dp
                    机器人：layout_weight =0＆GT;
                ＆LT; /＆的FrameLayout GT;
 

我在我的片段用它来取代另一个的一个片段

 广播接收器mBroadcastReceiver =新的广播接收器（）{
                @覆盖
                公共无效的onReceive（上下文的背景下，意图意图）{
                    Toast.makeText（上下文中，Recived，
                               Toast.LENGTH_LONG）.show（）;
                    FieldVisitFragment fieldvisitFragment =新FieldVisitFragment（）;
                    FragmentManager fragmentManager = getFragmentManager（）;
                    FragmentTransaction fragmentTransaction = fragmentManager
                            .beginTransaction（）;
                    fragmentTransaction.replace（需要知道什么ID通过，fieldvisitFragment）;
                    fragmentTransaction.commit（）;
                }            };
 

我的显示卡的布局，如下图所示，我使用Fragement android.support.v4库。请帮助。

 ＆LT; TabHost
            机器人：ID =@机器人：ID / tabhost
            机器人：layout_width =FILL_PARENT
            机器人：layout_height =900dp           机器人：layout_alignParentBottom =真            ＆GT;            ＆LT;的LinearLayout
                机器人：layout_width =FILL_PARENT
                机器人：layout_height =FILL_PARENT
                机器人：方向=垂直＆GT;                ＆LT;的FrameLayout
                    机器人：ID =@机器人：ID / tabcontent
                    机器人：layout_width =0dp
                    机器人：layout_height =0dp
                    机器人：layout_weight =0＆GT;
                ＆LT; /＆的FrameLayout GT;                ＆LT; android.support.v4.view.ViewPager
                    机器人：ID =@ + ID / viewpager
                    机器人：layout_width =FILL_PARENT
                    机器人：layout_height =135​​dp
                    机器人：layout_weight =1＆GT;
                ＆LT; /android.support.v4.view.ViewPager>                ＆LT; TabWidget
                    机器人：ID =@机器人：ID /标签
                    机器人：layout_width =match_parent
                    机器人：layout_height =WRAP_CONTENT
                    机器人：方向=横向＆GT;
                ＆LT; / TabWidget＆GT;
            ＆LT; / LinearLayout中＆GT;
        ＆LT; / TabHost＆GT;
 

解决方案

使用这样的：

  Fragment.replace（RES_ID，fragement更换）;
 

Hi I am new to Android and am using PageViewer in my project to show Tab swiping and other such stuff

I have used 4 tabs and and used fragments for each tab Now 1 of the tabs I have a list on which button is there to call another fragment on same Tab i.e. I need to replace the fragment on the same tab .

I have hit upon this stack question as seen in link which says to use Broadcast listener to call upon fragment . I used it in my Fragment class .

http://stackoverflow.com/questions/22265378/how-to-call-a-fragment-from-baseadapter-class-android/22265433#22265433

I get an error where I need to call upon the frame layout

as it uses android id if I change it to @+id then it gives error

   <FrameLayout
                    android:id="@android:id/tabcontent"
                    android:layout_width="0dp"
                    android:layout_height="0dp"
                    android:layout_weight="0" >
                </FrameLayout>

I am using this in my Fragment to replace the one Fragment by another

BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
                @Override
                public void onReceive(Context context, Intent intent) {
                    Toast.makeText(context, "Recived", 
                               Toast.LENGTH_LONG).show();
                    FieldVisitFragment fieldvisitFragment = new FieldVisitFragment();
                    FragmentManager fragmentManager = getFragmentManager();
                    FragmentTransaction fragmentTransaction = fragmentManager
                            .beginTransaction();
                    fragmentTransaction.replace(need to know what id to pass, fieldvisitFragment);
                    fragmentTransaction.commit();
                }



            };

My layout for displaying tab is as seen below and I am using android.support.v4 libraries for Fragement . Kindly help .

<TabHost
            android:id="@android:id/tabhost"
            android:layout_width="fill_parent"
            android:layout_height="900dp" 

           android:layout_alignParentBottom="true"

            >

            <LinearLayout
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:orientation="vertical" >

                <FrameLayout
                    android:id="@android:id/tabcontent"
                    android:layout_width="0dp"
                    android:layout_height="0dp"
                    android:layout_weight="0" >
                </FrameLayout>

                <android.support.v4.view.ViewPager
                    android:id="@+id/viewpager"
                    android:layout_width="fill_parent"
                    android:layout_height="135dp"
                    android:layout_weight="1" >
                </android.support.v4.view.ViewPager>

                <TabWidget
                    android:id="@android:id/tabs"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"


                    android:orientation="horizontal" >
                </TabWidget>
            </LinearLayout>
        </TabHost>

解决方案

Use this:

Fragment.replace("res_id",fragement to replace);
