我正在开发一个4标签应用程序。
我的一个片段是搜索片段,其中包含searchview,textview,listview。
fragmentSearch.java
JSONObject jsonobject = new JSONObject(result);
textView1.setText((String) jsonobject.get("count"));
Integer count = Integer.parseInt((String) jsonobject.get("count"));
if (count == 0) {
// There are no results
textView1.setText(getString(R.string.no_results, query_string));
} else {
// Display the number of results
String countString = getResources().getQuantityString(R.plurals.search_results,
count, new Object[] {count, query_string});
textView1.setText(countString);
// Specify the columns we want to display in the result
String[] from = new String[] { "title",
"artist",
"duration",
"url"};
// Specify the corresponding layout elements where we want the columns to go
int[] to = new int[] { R.id.title,
R.id.artist,
R.id.duration,
R.id.url};
// -- container for all of our list items
List<Map<String, String>> groupData = new ArrayList<Map<String, String>>();
// -- list item hash re-used
Map<String, String> group;
//create audio json array
JSONArray audios = jsonobject.getJSONArray("audio");
for (int i = 0; i < audios.length(); i++) {
JSONObject audio = audios.getJSONObject(i);
//get info
String title = audio.getString("title");
String artist = audio.getString("artist");
String duration = audio.getString("duration");
String durationformated = getDurationString(Integer.parseInt(duration));
String url = audio.getString("url");
// -- create record
group = new HashMap<String, String>();
group.put( "title", title );
group.put( "artist", artist );
group.put( "duration", durationformated );
group.put( "url", url );
groupData.add(group);
}
SimpleAdapter adapter = new SimpleAdapter(searchContext , groupData, R.layout.result,
from,
to );
listView1.setAdapter( adapter );
这是我的result.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">

android:layout_width="0dp"

<TextView

<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/artist"
android:layout_alignParentBottom="true"
android:layout_below="@id/artist"
android:layout_toLeftOf="@+id/play"
android:singleLine="true"
android:text="03:24"
android:textColor="#7D7D7D" />
<ImageButton
android:id="@+id/play"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_toLeftOf="@+id/download"
android:src="@drawable/play" />
<ImageButton
android:id="@+id/download"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:src="@drawable/download" />
</RelativeLayout>
我找不到任何方法让“播放”图像按钮对点击作出反应,我尝试过itemclicklistener,onclick属性......
有人可以提供示例代码或工作教程吗?
此外,我的java代码部分位于AsynTask的postexecute中。
答案 0 :(得分:0)
不确定什么会阻止你,但设置onClickListener总是对我有效。
答案 1 :(得分:0)
您需要处理适配器中的play
按钮,并且必须添加属性以播放按钮android:clickable="true"
答案 2 :(得分:0)
onClick和itemClickListener与片段进行交互。与片段完成交互后,必须使用侦听器类或其他内容将片段中的数据发送到父活动。
