我有一个列表视图，其设计类似于下面的代码，其中每个图片旁边都有一个 textview 和一个 edittext，我想要的是当单击按钮时我必须获取 edittextes 的数据。并且可能有一些没有任何数据的空编辑文本！但我不知道如何访问每个edittext，因为我不能以这种编码形式使用“findById”！任何人都可以帮助我吗？

    <?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" >

    <TextView
        android:id="@+id/selection"
        android:layout_width="30dp"
        android:layout_height="30dp" />

    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="512dp"
        android:drawSelectorOnTop="false" />

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0.79" >

 <Button
            android:id="@+id/button1"
            android:layout_width="100dp"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:text="Button" />

    <Button
            android:id="@+id/button2"
            android:layout_width="100dp"
            android:layout_height="match_parent"
            android:layout_alignParentRight="true"
            android:layout_alignParentTop="true"
            android:text="Button" />

    </RelativeLayout>

    </LinearLayout>

 <?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 = "wrap_content"
android:orientation   = "horizontal" >

    <ImageView
    android:id = "@+id/pic"
    android:padding       = "2dip"
    android:layout_width  = "100dp"
    android:layout_height = "100dp"
    android:src = "@drawable/download" />

<EditText
        android:id="@+id/editpizza"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:ems="10"
        android:height="5dp"
        android:inputType="number"
        android:width="10dp" >

        <requestFocus />
    </EditText>

    <TextView
    android:id = "@+id/label"
    android:layout_width  = "wrap_content"
    android:layout_height = "wrap_content"
    android:textSize      = "40sp" />

</LinearLayout>

爪哇代码：

 public class ListView extends ListActivity {
        /** Called when the activity is first created. */
        private TextView selection;
        private EditText choose;
        private static final String[] items = {"مخصوص", "مخلوط", "یونانی", "قارچ و گوشت", "پپرونی", "مرغ و قارچ", "سبزیجات", "دریایی"};

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.view);

            setListAdapter(new IconicAdapter());
            selection = (TextView)findViewById(R.id.selection);
            choose=(EditText) findViewById(R.id.editpizza);
        }

        public void OnListItemClick(ListView parent, View v, int position, long id){
            selection.setText(items[position]);

        }

        private String getModel(int position){

您可以在ArrayAdapter的getView()函数中执行此操作。IconicAdapter

首先使用 getView 函数膨胀您的视图

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.YourRowLayout, parent, false);

然后你可以使用

TextView txtViewSelection = (TextView) rowView.findViewById(R.id.editpizza);

获取你的 textView 或 EditText 或任何你想得到的

如果您的按钮在列表视图中，您也可以在 getView 函数中定义它的单击侦听器函数
