Question

我为listview开发了一个自定义适配器，但它的onclicklistner不能正常工作，尽管我没有在日志中收到任何错误。以下是代码

public class HospiRow extends AppCompatActivity {

private List<ContactData> hospiData = new ArrayList<ContactData>();
Intent intent;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.my_layout);

    hospiData.add(new ContactData("Shrotri Hospital", "Datta chowk, Yavatmal", "Phone Number 07232 232383", R.drawable.call_button3));
    hospiData.add(new ContactData("Tarak Hospital","Shani chowk, Yavatmal","Phone Number 07232 232383", R.drawable.call_button3));
    hospiData.add(new ContactData("Dattani Hospital","Shivagi nagar, Yavatmal","Phone Number 07232 232383", R.drawable.call_button3));
    hospiData.add(new ContactData("Chattani Hospital","Darda nagar, Yavatmal","Phone Number 07232 232383", R.drawable.call_button3));
    hospiData.add(new ContactData("Thakare Hospital","Anne Vidyalaya, Yavatmal","Phone Number 07232 232383", R.drawable.call_button3));
    hospiData.add(new ContactData("Bade Hospital","Laxminagar, Yavatmal","Phone Number 07232 232383", R.drawable.call_button3));
    hospiData.add(new ContactData("Rathode Hospital","Balaji Society, Yavatmal","Phone Number 07232 232383", R.drawable.call_button3));

    ArrayAdapter<ContactData> hospiAdapter = new DataAdapter(this, R.layout.hospi_row, hospiData);
    ListView myList = (ListView) findViewById(R.id.myFirstListView);
    myList.setAdapter(hospiAdapter);

    myList.setOnItemClickListener(
            new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    ContactData singleItem = (ContactData) parent.getItemAtPosition(position);
                    String number = singleItem.getTelephoneNumber();
                    Toast.makeText(HospiRow.this,number, Toast.LENGTH_LONG).show();
                    intent = new Intent(Intent.ACTION_DIAL);
                    intent.setData(Uri.parse("tel:" + number));
                    startActivity(intent);
                }
            }
    );

}

}

请帮忙

listview的XML代码是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

    <ListView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/myFirstListView"
        android:focusable="false"
        android:focusableInTouchMode="false"/>
</LinearLayout>

xml文件的名称是my_layout.xml

Answer 1

如果列表中的任何行项包含可聚焦或可点击的视图，则OnItemClickListener将无法正常工作。行项必须有一个像

这样的参数

android:descendantFocusability="blocksDescendants"

您的列表项xml必须如下所示。

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
  android:baselineAligned="false"
 android:descendantFocusability="blocksDescendants"
 android:gravity="center_vertical" >

 // your other widgets here

 </LinearLayout>

Answer 2

按钮或任何视图，请确保该项目无法点击。

android:focusable="false"
android:focusableInTouchMode="false"

如果它不能与SimpleAdapter一起使用，请尝试使用CustomListViewAdapter并在每个视图中使用xml中的clickable false。

Answer 3

将setClickable设置为false，以便在适配器的xml文件中对此项进行排序。

<TextView 
.....
android:clickable="false"
....
/>

如果列表的任何行项包含可聚焦或可点击的视图，则OnItemClickListener将不起作用。
