Question

我是Android开发的新手，我对如何将片段活动添加到片段活动（我认为它的调用片段）感到困惑。我正在修改源代码。

我有一个名为fragment_ftp.xml的布局文件，其格式如下

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:ads="http://schemas.android.com/apk/res-auto">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text=""
        android:id="@+id/statusText"
        android:layout_above="@+id/startStopButton"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="99dp" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text=""
        android:id="@+id/ftpAddressText"
        android:layout_below="@+id/startStopButton"
        android:layout_centerHorizontal="true" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/start_ftp"
        android:id="@+id/startStopButton"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textColor="@color/primary_red"
        android:text=""
        android:id="@+id/warningText"
        android:layout_above="@+id/startStopButton"
        android:layout_centerHorizontal="true" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/ftp_image"
        android:layout_above="@+id/warningText"
        android:layout_centerHorizontal="true" />
    <RelativeLayout
        android:id="@+id/relativeLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true">

        <com.google.android.gms.ads.AdView
            android:id="@+id/adView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            ads:adSize="SMART_BANNER"
            ads:adUnitId="@string/banner_home_footer" />
    </RelativeLayout>

</RelativeLayout>

我添加了admob横幅，在预览中，我可以看到。请查看以下屏幕截图。

但问题在于，我应该在哪里编写这个admob横幅的java代码。我没有为此fragment_ftp.xml提供相应的活动。

搜索fragment_ftp，我只能看到一个java文件，如下所示。 FTPServerFragment.java

package com.filename.fragments;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.content.SharedPreferences;
import android.net.ConnectivityManager;


public class FTPServerFragment extends Fragment {

    TextView statusText,warningText,ftpAddrText;
    Button ftpBtn;
    Futils utils = new Futils();
    private MainActivity mainActivity;
    private View rootView;
    private BroadcastReceiver mWifiReceiver = new  BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            ConnectivityManager conMan = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo netInfo = conMan.getActiveNetworkInfo();
            if (netInfo != null && netInfo.getType() == ConnectivityManager.TYPE_WIFI){
                warningText.setText("");
            }
            else{
                stopServer();
                statusText.setText(utils.getString(getContext(),R.string.ftp_status_not_running));
                warningText.setText(utils.getString(getContext(),R.string.ftp_no_wifi));
                ftpAddrText.setText("");
                ftpBtn.setText(utils.getString(getContext(),R.string.start_ftp));
            }
        }
    };
    private BroadcastReceiver ftpReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();

                warningText.setText("");
                ftpAddrText.setText(getFTPAddressString());
                ftpBtn.setText(utils.getString(getContext(),R.string.stop_ftp));
            }
            else if(action == FTPService.ACTION_FAILEDTOSTART){
                statusText.setText(utils.getString(getContext(),R.string.ftp_status_not_running));
                warningText.setText("Oops! Something went wrong");
                ftpAddrText.setText("");
                ftpBtn.setText(utils.getString(getContext(),R.string.start_ftp));
            }

                }

    }
    private String getFTPAddressString(){
        return "ftp://"+FTPService.getLocalInetAddress(getContext()).getHostAddress()+":"+FTPService.getPort();
    }
}

我这是java页面，我将写一个admob调用？

尝试使用此代码解决问题

您的代码Java必须像这样在FTPServerFragement的onCreateView函数中添加：

public class FTPServerFragment extends Fragment {

TextView statusText,warningText,ftpAddrText;
Button ftpBtn;
Futils utils = new Futils();
private MainActivity mainActivity;
private View rootView;
private BroadcastReceiver mWifiReceiver = new  BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        ConnectivityManager conMan = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo netInfo = conMan.getActiveNetworkInfo();
        if (netInfo != null && netInfo.getType() == ConnectivityManager.TYPE_WIFI){
            warningText.setText("");
        }
        else{
            stopServer();
            statusText.setText(utils.getString(getContext(),R.string.ftp_status_not_running));
            warningText.setText(utils.getString(getContext(),R.string.ftp_no_wifi));
            ftpAddrText.setText("");
            ftpBtn.setText(utils.getString(getContext(),R.string.start_ftp));
        }
    }
};
private BroadcastReceiver ftpReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if(action == FTPService.ACTION_STARTED) {
            statusText.setText(utils.getString(getContext(), R.string.ftp_status_running));
            warningText.setText("");
            ftpAddrText.setText(getFTPAddressString());
            ftpBtn.setText(utils.getString(getContext(),R.string.stop_ftp));
        }
