android - 带有 4 个 TextView 的 ListView

Question

我必须创建一个 ListView ，其中单行有 4 个 TextView 。我的问题是我不明白如何使用适配器，所以有人可以帮助我了解适配器及其实现吗？

这是我的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:orientation="vertical" >




<TextView
    android:id="@+id/textView1"
    android:layout_width="192dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_marginBottom="20dp"
    android:text="Grazie per aver parcheggiato da noi!"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<ListView
    android:id="@+id/mylist"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
</ListView>


<Button
    android:id="@+id/btnEsci"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="Torna a scelta" />

</LinearLayout>

这是单行(single_feed)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

 <!-- TEXT OF FEED -->

 <TextView
        android:id="@+id/txtId"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Numero macchina: #"
        android:textAppearance="?android:attr/textAppearanceMedium" />

  <TextView
        android:id="@+id/txtTarga"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Targa: #"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <TextView
        android:id="@+id/txtOra"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Ora ingresso: #"
        android:textAppearance="?android:attr/textAppearanceMedium" />


    <TextView
        android:id="@+id/txtCosto"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Prezzo uscita: #"
        android:textAppearance="?android:attr/textAppearanceMedium" 
        android:lines="1" 
        />

这是我的适配器:

public class MioAdapter extends ArrayAdapter<String> {
        private final Context context;
        private final String[] values;

        public MioAdapter(Context context, String[] values) {
            super(context, R.layout.single_feed, values);
            this.context = context;
            this.values = values;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View rowView = inflater.inflate(R.layout.single_feed, parent, false);
            TextView textView = (TextView) rowView.findViewById(R.id.label);
            textView.setText(values[position]);
            // Change the icon for Windows and iPhone


            return rowView;
        }

最后这是我的 Activity :

public class checkout extends Activity{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        //apro la view
        super.onCreate(savedInstanceState);
        setContentView(R.layout.checkout);

        //gestsco l'adapter per creare la lista
        public void onCreate(Bundle icicle) {
            super.onCreate(icicle);
            String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                    "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                    "Linux", "OS/2" };
            MioAdapter adapter = new MioAdapter(this, values);
            setListAdapter(adapter);
};

有人可以帮我处理适配器吗？感谢所有可以帮助我解决这个简单问题的人:)

See this Custom listView

行中有两个 TextView ，您只需添加四个 TextView ，因此添加行布局文件。并在 TextView 中添加 android:maxLines="1" 用于单行 TextView 。
