Question

我终于让我的广告在我的ListView片段中工作，但现在我收到一个奇怪的逻辑错误。问题似乎是跟踪广告的位置（位置0）和列表中的其他项目。第一个项目由添加替换，单击列表上的任何项目以进行更新，然后返回到项目列表。列表名称似乎没有问题。

以下是我使用adMob XML代码进行的修订，在我的ListFragment类中使用了几行java，

我的XML代码如下：

  <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      >
    <LinearLayout 
      android:id="@+id/adsContainer"
      android:orientation="vertical"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"/>
    <com.google.android.gms.ads.AdView
      xmlns:ads="http://schemas.android.com/apk/res-auto"
      android:id="@+id/adView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      ads:adUnitId="ca-app-pub-9999999999999999999999999"
      ads:adSize="BANNER"/>
    <ListView
      android:id="@android:id/list"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      >
     </ListView>
     <ListView
       android:id="@android:id/empty"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:paddingLeft="4dp"
       android:paddingRight="4dp"
       android:text="@string/new_empty_desc" 
      >
      </ListView>
</

在我的类中，公共类BxListFragment扩展了SherlockListFragment：

我正在尝试在上面的ListFragment中添加这段代码。目前我得到一个语法错误findVuewById（int）undefined。我的问题是，我最好在我的listfragment中插入这段代码，将广告放在上面的XML中吗？ @Override public void onListItemClick(ListView l, View v, int position, long id) { Bxied c = ((BxiedAdapter)getListAdapter()).getItem(position); // Start Bxied Activity Intent i = new Intent(getSherlockActivity(), BxiedPagerActivity.class); i.putExtra(BxiedFragment.EXTRA_BULLIED_ID, c.getId()); startActivityForResult(i, 0); } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { ((BxiedAdapter)getListAdapter()).notifyDataSetChanged(); } @Override public void onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu, MenuInflater inflater) { super.onCreateOptionsMenu(menu, inflater); inflater.inflate(R.menu.fragment_bxied_list, menu); }

  @Override
  public void onCreateContextMenu(ContextMenu menu,View v, ContextMenuInfo menuInfo) {
      getActivity().getMenuInflater().inflate(R.menu.bxied_list_item_context, menu);
  }

  @Override
  public boolean onContextItemSelected(android.view.MenuItem item) {
      AdapterContextMenuInfo info = (AdapterContextMenuInfo)item.getMenuInfo();
      int position = info.position;
      BxiedAdapter adapter = (BxiedAdapter)getListAdapter();
      Bxied bxied = adapter.getItem(position);

      switch (item.getItemId()) {
         case R.id.menu_item_delete_bxied:
             BxiedLab.get(getActivity()).deleteBxied(bxied);
             adapter.notifyDataSetChanged();
             return true;
      }
      return super.onContextItemSelected(item);
  }

  private class BxiedAdapter extends ArrayAdapter<Bxied> {
      public BxiedAdapter(ArrayList<Bxied> bxied) {
          super(getSherlockActivity(), android.R.layout.simple_list_item_1, bxied);
      }    

  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
       Log.i("1", "msg1");

      // If we weren't given a view, inflate one
      if (convertView == null) {
          convertView = getSherlockActivity().getLayoutInflater()
                  .inflate(R.layout.list_item_bxied, null);
      }  

      // Enter the view of this Bxied Attack
      Bxied c = getItem(position);

      TextView titleTextView =
              (TextView)convertView.findViewById(R.id.bxied_list_item_titleTextView);
      titleTextView.setText(c.getTitle());
      TextView dateTextView =
              (TextView)convertView.findViewById(R.id.bxied_list_item_dateTextView);
      dateTextView.setText(DateFormat.format("EEEE, MMM dd, yyyy  hh : mm a", c.getDate()).toString());

      CheckBox resolvedCheckBox =
              (CheckBox)convertView.findViewById(R.id.bxied_list_item_resolvedCheckBox);
      resolvedCheckBox.setChecked(c.isResolved());
      return convertView;
  }

@Override public void onResume() { super.onResume(); ((BxiedAdapter)getListAdapter()).notifyDataSetChanged(); } }

Answer 1

问题可能与将0设为特殊情况有关，但拥有数据源的元素也为零。列表和适配器不再对齐。

将广告视图放在标题中可能会有效。看这里： https://developer.android.com/reference/android/widget/ListView.html#addHeaderView%28android.view.View,%20java.lang.Object,%20boolean%29

Answer 2

我认为您在问“我应该在哪里放置加载广告的代码？”。

如果是，那么您要将以下代码添加到ListFragment：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  AdView adView = (AdView)this.findViewById(R.id.adView);

  AdRequest adRequest = new AdRequest.Builder()
      .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
      .addTestDevice("TEST_DEVICE_ID")
      .build();

  adView.loadAd(adRequest);

  ...
}

Answer 3

仅供参考 - 我终于明白了。我最终在我的GetView中正确插入了所有广告逻辑，并在顶部发布了广告

以下是我的代码：

@Override public View getView(int position, View convertView, ViewGroup parent) { if (position == 0) { if (convertView instanceof AdView) { // Don’t instantiate new AdView, reuse old one return convertView; } else { Context mainActivity = getActivity(); adView = new AdView(mainActivity); adView.setAdUnitId("ca-app-pub-9999998888888888"); adView.setAdSize(AdSize.BANNER); // Convert the default layout parameters so that they play nice with // ListView. float density = mainActivity.getResources().getDisplayMetrics().density; int height = Math.round(AdSize.BANNER.getHeight() * density); AbsListView.LayoutParams params = new AbsListView.LayoutParams( AbsListView.LayoutParams.FILL_PARENT, height); adView.setLayoutParams(params); AdRequest adRequest = new AdRequest.Builder() .addTestDevice(AdRequest.DEVICE_ID_EMULATOR) .addTestDevice("TEST_DEVICE_ID") .build(); adView.loadAd(adRequest); } convertView = adView; } else { convertView = getSherlockActivity().getLayoutInflater() .inflate(R.layout.list_item_bxied,null); // Enter the view of this Bxlied Attack // If we weren't given a view, inflate one // Enter the view of this Bxlied Attack Bxlied c = getItem(position); TextView titleTextView = (TextView)convertView.findViewById(R.id.bxied_list_item_titleTextView); titleTextView.setText(c.getTitle()); TextView dateTextView = (TextView)convertView.findViewById(R.id.bxied_list_item_dateTextView); dateTextView.setText(DateFormat.format("EEEE, MMM dd, yyyy hh : mm a", c.getDate()).toString()); CheckBox resolvedCheckBox = (CheckBox)convertView.findViewById(R.id.bxied_list_item_resolvedCheckBox); resolvedCheckBox.setChecked(c.isResolved()); } return convertView; } }
@Override public View getView(int position, View convertView, ViewGroup parent) { if (position == 0) { if (convertView instanceof AdView) { // Don’t instantiate new AdView, reuse old one return convertView; } else { Context mainActivity = getActivity(); adView = new AdView(mainActivity); adView.setAdUnitId("ca-app-pub-9999998888888888"); adView.setAdSize(AdSize.BANNER); // Convert the default layout parameters so that they play nice with // ListView. float density = mainActivity.getResources().getDisplayMetrics().density; int height = Math.round(AdSize.BANNER.getHeight() * density); AbsListView.LayoutParams params = new AbsListView.LayoutParams( AbsListView.LayoutParams.FILL_PARENT, height); adView.setLayoutParams(params); AdRequest adRequest = new AdRequest.Builder() .addTestDevice(AdRequest.DEVICE_ID_EMULATOR) .addTestDevice("TEST_DEVICE_ID") .build(); adView.loadAd(adRequest); } convertView = adView; } else { convertView = getSherlockActivity().getLayoutInflater() .inflate(R.layout.list_item_bxied,null); // Enter the view of this Bxlied Attack // If we weren't given a view, inflate one // Enter the view of this Bxlied Attack Bxlied c = getItem(position); TextView titleTextView = (TextView)convertView.findViewById(R.id.bxied_list_item_titleTextView); titleTextView.setText(c.getTitle()); TextView dateTextView = (TextView)convertView.findViewById(R.id.bxied_list_item_dateTextView); dateTextView.setText(DateFormat.format("EEEE, MMM dd, yyyy hh : mm a", c.getDate()).toString()); CheckBox resolvedCheckBox = (CheckBox)convertView.findViewById(R.id.bxied_list_item_resolvedCheckBox); resolvedCheckBox.setChecked(c.isResolved()); } return convertView; } }

在listview片段中嵌入adView的android逻辑错误 - 最新的admob sdk - 使用XML和Java进行修订
