我一直在努力寻找解决方案，但收效甚微。我必须显示一个包含项目列表的弹出窗口。我能够显示窗口，但单击列表视图中的项目时，不会调用onitemclicklistener。如果能在这个问题上提供任何帮助，我们将不胜感激。
感谢
第1版：
public class PopUpWindowActivity extends Activity {
/** Called when the activity is first created. */
String[] countries = new String[] {
"India", "USA", "Canada"
};
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout ll = new LinearLayout(this);
ListView lv = new ListView(this);
lv.setAdapter(new ArrayAdapter < String > (this, android.R.layout.simple_list_item_1, countries));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView <? > arg0, View arg1, int arg2,
long arg3) {
Log.v("clicked", (String)((TextView) arg1).getText());
}
});
ll.addView(lv);
setContentView(ll);
}
}
在上面的代码中，我试图创建一个布局，在其中添加了一个列表视图。这将使列表视图不再可单击。我必须这样做，因为我正在尝试实现一个弹出窗口，其中应该有多个项目和一个列表视图。
列表和列表中的项目是否设置为可单击？以编程方式。。。
ListView myList = (ListView) findViewById(R.id.list_view_id);
myList.setClickable(true);
或者在XML中。。。
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:clickable="true">
...
</ListView>
我想你做到了，但有时我们甚至错过了显而易见的：）
编辑：
在Android教程中，以下是如何以编程方式设置onItemClickListener。
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// When clicked perform some action...
}
});

这是我的XML
<?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" >
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/list" />
</LinearLayout>
这是我的代码
public class HelloAndroidActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String[] countries = getResources().getStringArray(R.array.countries_array);
ListView lv = (ListView) findViewById(R.id.list);
lv.setAdapter(new ArrayAdapter < String > (this, R.layout.list_item, countries));
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView <? > arg0, View view, int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_SHORT).show();
}
});
}
}
ListView myList;
myList = (ListView)findViewById(list_vew_id_in_xml)
myList.setOnItemClickListener(new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
//Toast.makeText(BritishCouncilActivity.this, "" + position, 2).show();
}
});
编辑的答案
应用此示例Please This Works For You我已经测试了此代码
//Listview活动.java
package com.anl.lk;
public class ListviewActivity extends ListActivity {
static final String[] COUNTRIES = new String[] {
"Afghanistan", "Albania", "Algeria", "American Samoa",
"Andorra", "Angola", "Anguilla", "Antarctica",
"Antigua and Barbuda", "Argentina", "Armenia", "Aruba",
"Australia", "Austria", "Azerbaijan", "Bahrain",
"Bangladesh", "Barbados", "Belarus", "Belgium", "Belize",
"Benin", "Bermuda", "Bhutan", "Bolivia",
"Bosnia and Herzegovina", "Botswana", "Bouvet Island",
"Brazil", "British Indian Ocean Territory"
};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter < String > (this,
android.R.layout.simple_list_item_1, COUNTRIES));
getListView().setTextFilterEnabled(true);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
new AlertDialog.Builder(this)
.setTitle("Hello")
.setMessage("from " + getListView().getItemAtPosition(position))
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {}
})
.show();
Toast.makeText(ListviewActivity.this,
"ListView: " + l.toString() + "n" +
"View: " + v.toString() + "n" +
"position: " + String.valueOf(position) + "n" +
"id: " + String.valueOf(id),
Toast.LENGTH_LONG).show();
}
}
//第一页
package com.anl.lk;
public class FirstPage extends Activity {
@override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent sam = new Intent(FirstPage.this, ListviewActivity.class);
startActivity(sam);
}
});
}
}
//清单文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.anl.lk"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >

android:name=".FirstPage" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ListviewActivity" android:theme="@android:style/Theme.Dialog"></activity>
</application>
请使用此代码，它有您的解决方案
针对任何列表视图项插入此属性
android:onClick="buttonClicked"
然后在你的代码
public void buttonClicked(View view)
{
//Do what you want to do..
}
