У меня большая проблема с моим новым приложением, я использую новую функцию FragmentActivity, предоставляемую новым плагином ATD для Eclipse. Пошаговое руководство создало для меня основную функцию FragmentActivity с 3-мя разделами.Android admob в FragmentActivity
Это код:
package com.italiandevteam.chuck;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.Toast;
public class ChuckActivity extends FragmentActivity{
/**
* The {@link android.support.v4.view.PagerAdapter} that will provide fragments for each of the
* sections. We use a {@link android.support.v4.app.FragmentPagerAdapter} derivative, which will
* keep every loaded fragment in memory. If this becomes too memory intensive, it may be best
* to switch to a {@link android.support.v4.app.FragmentStatePagerAdapter}.
*/
SectionsPagerAdapter mSectionsPagerAdapter;
/**
* The {@link ViewPager} that will host the section contents.
*/
ViewPager mViewPager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chuck);
// Create the adapter that will return a fragment for each of the three primary sections
// of the app.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_chuck, menu);
return true;
}
/**
* A {@link FragmentPagerAdapter} that returns a fragment corresponding to one of the primary
* sections of the app.
*/
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int i) {
Fragment fragment = new DummySectionFragment();
Bundle args = new Bundle();
args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, i + 1);
fragment.setArguments(args);
return fragment;
}
@Override
public int getCount() {
return 3;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0: return getString(R.string.title_section1);
case 1: return getString(R.string.title_section2);
case 2: return getString(R.string.title_section3);
}
return null;
}
}
/**
* A dummy fragment representing a section of the app, but that simply displays dummy text.
*/
public static class DummySectionFragment extends Fragment {
public DummySectionFragment() {
}
public static final String ARG_SECTION_NUMBER = "section_number";
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//Create the view
}
}
}
У меня есть вставки в onCreateView мой переключатель, чтобы показать другую раскладку таким образом:
switch(args.getInt(ARG_SECTION_NUMBER)){
case 1:{
myView = getLayoutInflater(null).inflate(R.layout.layout_1, null);
break;
}
case 2:{
myView = getLayoutInflater(null).inflate(R.layout.layout_2, null);
break;
}
}
return myView
Теперь я действительно нужно добавить AdMob в свой проект, но если я положил этот коэффициент в метод onCreate
AdView adView;
// Create the adView
adView = new AdView(this, AdSize.BANNER, "a14eedc43db2122");
// Lookup your LinearLayout assuming it’s been given
// the attribute android:id="@+id/mainLayout"
LinearLayout layout = (LinearLayout)findViewById(R.id.linearLayout);
// Add the adView to it
layout.addView(adView);
AdRequest request = new AdRequest();
request.addTestDevice(AdRequest.TEST_EMULATOR);
request.addTestDevice("B7709F3C1336BFAEFAD6E50877E3211F");
// Initiate a generic request to load it with an ad
adView.loadAd(request);
мой a С. разобьет и LogCat:

Я не могу найти способ, чтобы вставить AdMob в моем проекте, вы можете мне помочь?
EDIT:
это мой activity_chuck.xml
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ChuckActivity">
<!--
This title strip will display the currently visible page title, as well as the page
titles for adjacent pages.
-->
<android.support.v4.view.PagerTitleStrip android:id="@+id/pager_title_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#000"
android:textColor="#fff"
android:paddingTop="4dp"
android:paddingBottom="4dp" />
</android.support.v4.view.ViewPager>
и это мой layout_1 (это похоже на layout_2):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
EDIT 2: Теперь с AdMob код в коммутаторе, он работает, но только для первой страницы, если я прокручу во второй раздел, который я разбил, и это LogCat:

Я отредактировал свой вопрос –
Ваши макеты выглядят отлично. Он говорит, что исключение NullPointerException происходит на 'com.italiandevteam.chuck.ChuckActivity.onCreate (ChuckActivity.java:66)'. Что именно есть (строка 66)? Это 'findViewById (R.id.pager)' или что-то еще? – chrulri
это layout.addView (adView); он отказывается от всего проекта с admob-кодом –
