In this application, the List have 10 students. There are four grades provided for the exam which was conducted to those Students. One student can adapt only one grade from the four.

老师会在列表视图。

我的XML文件Studentlist.xml是如下，..

My xml file Studentlist.xml is as follow,..

<?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="vertical" >
<ListView
    android:id="@+id/listView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >
</ListView>
</LinearLayout>

和我的row.xml文件如下，......

and my row.xml file is as follow,...

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="500dp"
android:layout_height="fill_parent"
android:padding="10dp" >

<TableRow>

    <TextView
        android:id="@+id/SNo"
        style="@style/text"
        android:layout_width="40dp"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/StudNo"
        style="@style/text"
        android:layout_width="80dp"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/StudName"
        style="@style/text"
        android:layout_width="180dp"
        android:layout_height="wrap_content" />

    <RadioGroup
        android:id="@+id/radioGroup1"
        android:layout_width="160dp"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >

        <RadioButton
            android:id="@+id/radio0"
            android:layout_width="40dp"
            android:layout_height="wrap_content"
            android:checked="true" />

        <RadioButton
            android:id="@+id/radio1"
            android:layout_width="40dp"
            android:layout_height="wrap_content" />

        <RadioButton
            android:id="@+id/radio2"
            android:layout_width="40dp"
            android:layout_height="wrap_content" />

        <RadioButton
            android:id="@+id/radio3"
            android:layout_width="40dp"
            android:layout_height="wrap_content" />
    </RadioGroup>
</TableRow>

推荐答案

您可以使用一个类从ArrayAdapter继承，并重写它的getView（）方法。

You can use a class inheriting from ArrayAdapter, and overriding its getView() method.

public class StudentAdapter extends ArrayAdapter<Student> {

protected LayoutInflater inflater;

    public StudentAdapter(final Context context) {
        super(context, 0);
        inflater = (LayoutInflater) ((Context) context)
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        // Note: You should optimize here with re-using convertView

        View rowView = inflater.inflate(R.layout.user_address_row_layout,
                parent, false);
        TextView sNo = (TextView) rowView.findViewById(R.id.sNo);
        sNo.setText(getItem(position).number);
            // same for every field of the row
            // ...

        return rowView;
    }

 }
