Question

我有一个自定义listView.xml，其listView为。

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@null" >

    <ListView
        android:id="@+id/searchList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/txtSearchFor"
        android:background="@color/Black" >
    </ListView>

</RelativeLayout>

此listview包含一个ImageView，2个TextViews和一个RatingBar（item_list.XML），如下所示。

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <RelativeLayout
        android:id="@+id/rel_SearchLayout01"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" >

        <ImageView
            android:id="@+id/img_searchBookCoverPhoto"
            android:layout_width="70dp"
            android:layout_height="100dp"
            android:layout_margin="5dp"
            android:background="@drawable/rounded_image_borders"
            android:focusable="false"
            android:src="@drawable/book1" />

        <TextView
            android:id="@+id/txt_searchBookTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignTop="@+id/img_searchBookCoverPhoto"
            android:layout_marginTop="10dp"
            android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
            android:focusable="false"
            android:text="The Basic Doctrine Of Islam"
            android:textColor="@color/White"
            android:textSize="16sp" />

        <TextView
            android:id="@+id/txt_searchAutherName"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/txt_searchBookTitle"
            android:layout_marginTop="2dp"
            android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
            android:focusable="false"
            android:text="By: Andrew J Newman"
            android:textColor="@color/SkyBlue"
            android:textSize="14sp" />

        <RatingBar
            android:id="@+id/searchRatingbar"
            style="?android:attr/ratingBarStyleSmall"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/txt_searchAutherName"
            android:layout_marginTop="12dp"
            android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
            android:focusable="false"
            android:isIndicator="false"
            android:numStars="5"
            android:rating="5"
            android:stepSize="1" />
    </RelativeLayout>

</RelativeLayout>

我的问题是我有Listview的点击事件，如下所示

enter image description here

但它不起作用，我真的很惊讶，为什么会发生这种情况

你可以看到我也设置了这个

android:focusable="false"

用于我的自定义listView中的所有视图。

这里也是自定义适配器的代码。

public class BookSearchResultActivity extends Activity {

    static final String URL = "http://www.shiaislamiclibrary.com/requesthandler.ashx";
    static final String KEY_ITEM = "Book"; // parent node

    static final String KEY_BOOKTITLE = "BookTitle";
    static final String KEY_BOOKCODE = "BookCode";
    static final String KEY_BOOKIMAGE = "BookImage";

    ArrayList<String> BookTitle = new ArrayList<String>();
    ArrayList<String> BookCoverPhotos = new ArrayList<String>();
    ArrayList<String> BookAuther = new ArrayList<String>();

        Intent getInfoIntent = getIntent();
        keyWordsSearch = getInfoIntent.getStringExtra("SEARCH_KEYWORDS");
        language = getInfoIntent.getStringExtra("LANG");

        ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        // checking for availbe internet Connection

Answer 1

您可以在getView() ConvertView中使用OnclickListener实施convertView.(new View.OnClickListener(){ @Override public void onClick(View view) { //write your code here } });之类的其他替代方案

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

            if(convertView == null) /* Create a new row view */
            {
                convertView = inflater.inflate(R.layout.simplerow, null);
            }

        convertView.setOnClickListener(new View.OnClickListener()
            {
                @Override
                public void onClick(View v)
                {
                    //your implementation.
                }
            }


    }

请告诉我这个替代方案是否正常

Answer 2

请更新以下item_list.xml文件的代码，它将解决您的问题。

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

    <RelativeLayout
        android:id="@+id/rel_SearchLayout01"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" >

        <ImageView
            android:id="@+id/img_searchBookCoverPhoto"
            android:layout_width="70dp"
            android:layout_height="100dp"
            android:layout_margin="5dp"
            android:src="@drawable/ic_launcher" />

        <TextView
            android:id="@+id/txt_searchBookTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignTop="@+id/img_searchBookCoverPhoto"
            android:layout_marginTop="10dp"
            android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
            android:text="The Basic Doctrine Of Islam"
            android:textSize="16sp" />

        <TextView
            android:id="@+id/txt_searchAutherName"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/txt_searchBookTitle"
            android:layout_marginTop="2dp"
            android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
            android:text="By: Andrew J Newman"
            android:textSize="14sp" />

        <RatingBar
            android:id="@+id/searchRatingbar"
            style="?android:attr/ratingBarStyleSmall"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/txt_searchAutherName"
            android:layout_marginTop="12dp"
            android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
            android:numStars="5"
            android:rating="5"
            android:stepSize="1" />
    </RelativeLayout>

</RelativeLayout>

Answer 3

This可能适合您。

如果您想为不同的视图组件使用不同的侦听器，那么请执行此操作

sqView.ticker.setOnClickListener(new OnClickListener(){

                    @Override
                    public void onClick(View view) {
                        // TODO Auto-generated method stub
//write your code here
}
});

Answer 4

添加两者机器人：可点击=“假” 机器人：可聚焦= “假”

在item_list.XML

中

我认为问题会解决

Answer 5

在您的主Activity类中实现OnItemClickListener。

public class BookSearchResultActivity extends Activity implement OnItemClickListener {

//now implement unimplemented methods 
//and 
listView.setOnItemClickListener(this);
}

我希望，这会对你有所帮助。

Answer 6

在自定义ListView

中的所有窗口小部件的xml文件中进行虚拟可点击和可聚焦

onItemClicklistener（）;不适用于android中的自定义listView
