我試圖從PopupWindow中顯示一個ListView。但是當我試圖調用ListView的setOnItemClickListener什麼都沒有。在這裏它的Java文件Android ListView的PopupWindow中的setOnItemClickListener不叫
PopupWindowActivity.java
public class PopupWindowActivity extends Activity {
String[] data = { "DATA 1", "DATA 2", "DATA 3", "DATA 4", "DATA 5", "DATA 6" };
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.a);
final Button btnOpenPopup = (Button) findViewById(R.id.openpopup);
btnOpenPopup.setOnClickListener(new Button.OnClickListener() {
public void onClick(View arg0) {
LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.main, null);
final PopupWindow popupWindow = new PopupWindow(popupView,
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
ListView listView = (ListView) popupView.findViewById(R.id.listView1);
listView.setAdapter(new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,data));
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
System.out.println("Item Clicked");
popupWindow.dismiss();
}
});
popupWindow.showAsDropDown(btnOpenPopup, 20, -5);
}
});
}
}
這是第一個XML文件 A.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" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
<Button
android:id="@+id/openpopup"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Open Popup Window" />
</LinearLayout>
這誇大xml文件 main.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:background="@drawable/recording"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="30sp"
android:layout_marginLeft="30sp"
android:layout_marginRight="30sp"
android:layout_marginTop="100sp" >
<ListView
android:id="@+id/listView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000" >
</ListView>
</RelativeLayout>
</LinearLayout>
我在做什麼錯?
感謝
可以嘗試的ListView。setAdapter(new ArrayAdapter(MyBannerActivity.this,?代替getApplicationContext(), –
@ Dheeresh Singh:就這樣,沒有任何事情發生 – Mansi
按鈕點擊事件正在工作,但是listview的項目點擊列表工作不起作用 – rajpara
