我正在尝试在同一 Activity 中制作 WebView 和 ListView 。我有一个 ID 为 list_xc 的 ListView ，但在我的 内容中的 logcat 显示中必须有一个 ListView，其 id 属性为“android.R.id.list”。
这是我的布局文件:
<com.markupartist.android.widget.ActionBar
android:id="@+id/actionbar"
style="@style/ActionBar" />
<TextView
android:id="@+id/tv_xc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:layout_marginTop="3dp"
android:text="Cross Country (XC)"
android:textColor="#372c24"
android:textSize="20dp"
android:textStyle="bold" />
<WebView
android:id="@+id/webview_xc"
android:layout_width="match_parent"
android:layout_height="166dp" />
<ListView
android:id="@+id/list_xc"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
这是我的行布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:orientation="vertical" >
<TextView
android:id="@+id/tv_test"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp"
android:textColor="#424545" >
</TextView>
这是我的 Activity :
public class Information_XC_Activity extends ListActivity {
WebView mWebView;
TextView tv;
private Adapter_DetailPolXC adapterDetailPolXC;
private ListView mainListView;
// private ArrayAdapter<String> listAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.info_xc);
final ActionBar actionBar = (ActionBar) findViewById(R.id.actionbar);
actionBar.setTitle(getString(R.string.app_name));
int index = getIntent().getIntExtra("text", 0);
mWebView = (WebView) findViewById(R.id.webview_xc);
String temp = "<html><body>" + "<p align=\"justify\">"
+ getString(R.string.xc_info + index) + "</p> "
+ "</body></html>";
mWebView.loadData(temp, "text/html", "utf-8");
ArrayList<Entity_Detail_Product> arraylist = new ArrayList<Entity_Detail_Product>();
adapterDetailPolXC = new Adapter_DetailPolXC(this, R.layout.info_row,
arraylist);
mainListView = (ListView) findViewById(R.id.list_xc);
mainListView.setAdapter(adapterDetailPolXC);
new info_xc_dao(response).view_pol_xc();
}
pol_xc_Result response = new pol_xc_Result() {
@Override
public void gotResult(Object obj, String message, int action) {
// TODO Auto-generated method stub
// actionBar.setProgressBarVisibility(View.INVISIBLE);
@SuppressWarnings("unchecked")
ArrayList<Entity_Detail_Product> arrayList = (ArrayList<Entity_Detail_Product>) obj;
AlertDialog.Builder builder = new AlertDialog.Builder(
Information_XC_Activity.this);
if (arrayList == null) {
builder.setIcon(R.drawable.alert_warning);
builder.setTitle("Error");
builder.setMessage("Data Not Found !");
builder.setNegativeButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
}
});
AlertDialog alert = builder.create();
alert.show();
} else {
for (Entity_Detail_Product entity_Detail_Product : arrayList) {
adapterDetailPolXC.add(entity_Detail_Product);
}
adapterDetailPolXC.notifyDataSetChanged();
}
}
};
private class Adapter_DetailPolXC extends
ArrayAdapter<Entity_Detail_Product> {
private ArrayList<Entity_Detail_Product> items;
public Adapter_DetailPolXC(Context context, int textViewResourceId,
ArrayList<Entity_Detail_Product> items) {
super(context, textViewResourceId, items);
this.items = items;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = convertView;
if (v == null) {
LayoutInflater layoutInflater = (LayoutInflater) getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = (View) layoutInflater.inflate(R.layout.info_xc, null);
}
Entity_Detail_Product adapter_Detail_Product = items.get(position);
if (adapter_Detail_Product != null) {
TextView textView = (TextView) v.findViewById(R.id.tv_test);
if (textView != null)
textView.setText(adapter_Detail_Product.getModel_name());
}
return v;
}
}
这是 logcat:

非常感谢，我真的需要帮助。
最佳答案
因为您的 Information_XC_Activity 扩展了 ListActivity，所以它必须有一个 ListView，其 id 在错误消息中指定。改变这一行
android:id="@+id/list_xc"
为此:
android:id="@android:id/list"
