我有一个带有4个标签的片段,在一个标签中,我需要显示一个列表视图。我对代码的了解不多,但是有一些错误,而且我不确定我是不是做得正确,还是缺少简单的东西。这是我正在使用的代码
碎片活动
public class SupportFragment extends SherlockFragment{
String[] supporters = new String[] {
"Gulf Shores",
"Central",
"Spanish Fort",
"Jackson Heights",
"Summerdale",
"Atlas",
"Robertsdale",
"Eastern Shore"
};
int[] images = new int[] {
R.drawable.gulfshores,
R.drawable.central,
R.drawable.spanishfort,
R.drawable.jacksonheights,
R.drawable.summerdale,
R.drawable.atlas,
R.drawable.robertsdale,
R.drawable.easternshore
};
String[] church = new String[]{
"Chruch of Christ",
"Chruch of Christ",
"Chruch of Christ",
"Chruch of Christ",
"Chruch of Christ",
"Chruch of Christ",
"Chruch of Christ",
"Chruch of Christ"
};
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
ViewGroup root = (ViewGroup) inflater.inflate(R.layout.tab_support_layout, null);
List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();
for(int i=0;i<10;i++){
HashMap<String, String> hm = new HashMap<String,String>();
hm.put("sup", "Supporters : " + supporters[i]);
hm.put("chur","Church : " + church[i]);
hm.put("icon", Integer.toString(images[i]) );
aList.add(hm);
}
String[] from = {"sup", "chur", "icon"};
int[] to = {R.id.icon, R.id.sup, R.id.chur};
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.listview_layout, from, to);
ListView listView = (ListView) findViewById(R.id.listview);
listView.setAdapter(adapter);
return root;
}
}
我从这两行代码中收到错误
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.listview_layout, from, to);
和
ListView listView = (ListView) findViewById(R.id.listview);
我得到的错误是:
对于类型SupportFragment,未定义方法getBaseContext()
对于SupportFragment类型,未定义方法findViewById(int)
列表视图的XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/tableback" >
<TextView
android:id="@+id/textview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<ListView
android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
和listview布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="10dp"
android:paddingRight="10dp"
android:paddingBottom="10dp"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<TextView
android:id="@+id/sup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="15dp"
/>
<TextView
android:id="@+id/chur"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="10dp"
/>
</LinearLayout>
</LinearLayout>
您能提供的任何帮助将不胜感激
最佳答案
您没有FragmentActivity
您有Fragment
,因此您当然不能使用getBaseContext()
获取上下文,而必须使用getActivity()
。
如果要在片段中执行此操作,则还必须将View膨胀以使用findViewById
。但是,如果您想使用制表符,则需要一个FragmentActivity
来简化您的Fragments
。
您可以在片段onCreateView()
方法中为这样的视图充气:
View view = inflater.inflate(R.layout.myLayout, null);
然后,您可以像这样调用
findViewById
:[...]view.findViewById(...);
