没有调用我的getView方法来填充listview中的数据

Question

public class ListDetails extends ListActivity 
{
ImageButton imagebutton;
LoanDetails details;
ArrayList<String> CreateReqID1, OpenTime1, RequestSummary1, RequestStatus1;
TextView CreateReqID, OpenTime, RequestSummary, RequestStatus;
ListView list;
public void onCreate(Bundle savedInstanceState) 
{       
super.onCreate(savedInstanceState);
setContentView(R.layout.listdetails);           

CreateReqID1 =  (ArrayList<String>) getIntent().getExtras().get("details1");
OpenTime1 = (ArrayList<String>) getIntent().getExtras().get("details2");
RequestSummary1 = (ArrayList<String>) getIntent().getExtras().get("details3");
RequestStatus1 = (ArrayList<String>) getIntent().getExtras().get("details4");
setListAdapter(new MyAdapter(this, R.layout.requestlistview));        
}
private class MyAdapter extends ArrayAdapter<String> {
public MyAdapter(Context context, int resource) {
super(context, resource);           
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View row = inflater.inflate(R.layout.requestlistview, parent, false);

Log.i("values set", "success");
CreateReqID = (TextView) row.findViewById(R.id.createReq);
OpenTime = (TextView) row.findViewById(R.id.openTime);
RequestSummary = (TextView) row.findViewById(R.id.requestSumary);
RequestStatus = (TextView) row.findViewById(R.id.status);

CreateReqID.setText(CreateReqID1.get(position));
OpenTime.setText(OpenTime1.get(position));  
RequestSummary.setText(RequestSummary1.get(position));
RequestStatus.setText(RequestStatus1.get(position));        
return row;
}           
}
}

我有上面的代码将数据添加到listview中，但我的getview方法没有被调用，请告诉我原因。

我的listview xml显示在下面

<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"

我想动态填充文本视图，我在arraylist中得到了所有内容，但我的getView方法没有被调用。

Answer 1

您没有将字符串数组传递给ArrayAdapter。。ArrayAdapter使用传递的列表来计算要在视图中显示的项目数。。

查看ArrayAdapter的javadoc。您需要将对象的数组发送到其构造函数，或者调用add()方法之一将对象添加到Adapter。。

Answer 2

您错过了adatpar的getCount()方法。只需重写getCount方法并返回适当的计数。以下方法将强制您的getView被调用5次

@Override
public synchronized int getCount() {
return 5;
}
