我已经按照各种链接描述了这个问题的解决方案,到目前为止还没有解决办法,或者在我的案例中不适用。我想知道我的代码/自定义适配器是否存在问题?除了OnItemClickListener之外,我还尝试过使用XML进行点击。我尝试了各种可点击的配置(单个元素,线性布局和列表视图本身),并且没有此属性的归属。
我创建了一个包含预告片对象的ListView,它只是创建用于在列表视图中显示的字符串,以及用于youtube视频的查询参数。当您点击应用程序中的ListItem时,它意味着在YouTube中打开预告片,给出youtube视频的查询参数(由API提供)。
链接到显示的内容;我指的是底部的ListView: http://i.imgur.com/djM6r1G.png
这是我的片段类onCreateView:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
//....... (other views that function)
ListView trailerView = (ListView) rootView.findViewById(R.id.trailer_listview);
trailerView.setClickable(true);
trailerView.setAdapter(mTrailerAdapter);
trailerView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
Log.d(LOG_TAG, "item click");
Trailer trailer = mTrailerAdapter.getItem(position);
final String YT_BASE_URL = "http://www.youtube.com";
final String YT_OPTION_PATH = "watch";
final String YT_API_KEY_PARAM = "v";
Uri builtUri = Uri.parse(YT_BASE_URL).buildUpon()
.appendEncodedPath(YT_OPTION_PATH)
.appendQueryParameter(YT_API_KEY_PARAM, trailer.getURLkey())
.build();
startActivity(new Intent(Intent.ACTION_VIEW, builtUri));
}
});
}
这是我的适配器:
public class TrailerAdapter extends ArrayAdapter<Trailer> {
final String LOG_TAG = TrailerAdapter.class.getSimpleName();
public TrailerAdapter(Activity context, List<Trailer> trailers){
super(context, 0, trailers);
//gets created
}
@Override
public View getView(int position, View convertView, ViewGroup parent){
Trailer trailer = getItem(position);
if(convertView == null){
convertView = LayoutInflater.from(getContext()).inflate(R.layout.list_item_trailer, parent, false);
}
TextView trailerText = (TextView) convertView.findViewById(R.id.trailer_textview);
trailerText.setText(trailer.getDisplayString());
return convertView;
}
}
预告片类:
public class Trailer {
private String DisplayString;
private String URLkey;
public Trailer(String DisplayString, String URLkey){
this.DisplayString = DisplayString;
this.URLkey = URLkey;
}
public String getDisplayString(){
return DisplayString;
}
public String getURLkey(){
return URLkey;
}
}
创建了电影预告片的ListView,但ListView并不对应任何点击;然而,该应用程序确实记录了点击次数(LogCat显示的是0和1对应的)。这也是XML:
ListView本身:
<LinearLayout>
....
</ScrollView>
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/trailer_listview"
android:layout_marginLeft="25dp">
</ListView>
</LinearLayout>
ListView项目:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true">
<ImageView
android:layout_width="55dp"
android:layout_height="55dp"
android:id="@+id/trailer_playbutton"
android:src="@drawable/video_play_button"
android:layout_gravity="center"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="Trailer 1"
android:gravity="center"
android:layout_marginLeft="15dp"
android:id="@+id/trailer_textview"/>
</LinearLayout>
谢谢!

我认为你有焦点问题。刚刚把android:focusable =&#34; false&#34;机器人:focusableInTouchMode =&#34;假&#34;在你的所有ListView项目(包括ImageView和TextView)&#34;只需尝试这个xml&#34;
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true">
<ImageView
android:layout_width="55dp"
android:layout_height="55dp"
android:id="@+id/trailer_playbutton"
android:src="@drawable/video_play_button"
android:layout_gravity="center"
android:focusable="false"
android:focusableInTouchMode="false"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="Trailer 1"
android:gravity="center"
android:layout_marginLeft="15dp"
android:id="@+id/trailer_textview"
android:focusable="false"
android:focusableInTouchMode="false"
/>
</LinearLayout>
