私はカスタマイズされたカレンダーを作成し、イベントも表示しています..

私が必要なのは何ですか?現在、カレンダーの下のテキストビューにイベントを表示しています。ポップアップでイベントを表示する必要があります。これを実装するにはどうすればよいですか? どんな助けでも大歓迎です。事前にどうもありがとう..

イベントごとにテキストビューを追加しました。代わりにリストビューを追加して、イベントを入力する必要があります。とにかくポップアップとして表示するには、ダイアログを使用して内部にリストビューを表示できます。最初に、リスト レイアウトを作成します。次のようなものです。

list_layout

        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

         <ListView
            android:id="@+id/list"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:divider="#b5b5b5"
            android:dividerHeight="1dp" />
     </LinearLayout>

次に、次のような単純な TextView:

single_item_layout

 <LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"> 

     <TextView android:id="@+id/singleItem"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center_vertical"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:textStyle="bold"
        android:textSize="22dp"
        android:textColor="#FFFFFF"
        android:padding="10dp"
        android:text="blue thingy"
        android:background="#336699" />

</LinearLayout>

シンプルなメイン レイアウト:

最後に単純な Cal​​enderView アクティビティ:

gridview.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {
            // removing the previous view if added
            if (((LinearLayout) rLayout).getChildCount() > 0) {
                ((LinearLayout) rLayout).removeAllViews();
            }
            desc = new ArrayList<String>();
            date = new ArrayList<String>();
            ((CalendarAdapter) parent.getAdapter()).setSelected(v);
            String selectedGridDate = CalendarAdapter.dayString
                    .get(position);
            String[] separatedTime = selectedGridDate.split("-");
            String gridvalueString = separatedTime[2].replaceFirst("^0*",
                    "");// taking last part of date. ie; 2 from 2012-12-02.
            int gridvalue = Integer.parseInt(gridvalueString);
            // navigate to next or previous month on clicking offdays.
            if ((gridvalue > 10) && (position < 8)) {
                setPreviousMonth();
                refreshCalendar();
            } else if ((gridvalue < 7) && (position > 28)) {
                setNextMonth();
                refreshCalendar();
            }
            ((CalendarAdapter) parent.getAdapter()).setSelected(v);

            for (int i = 0; i < Utility.startDates.size(); i++) {
                if (Utility.startDates.get(i).equals(selectedGridDate)) {
                    desc.add(Utility.nameOfEvent.get(i));
                }
            }

        final Dialog dialog = new Dialog(CalenderView.this);
        dialog.setContentView(R.layout.list_layout);
        dialog.setTitle("Events");
        ListView listView = (ListView) dialog.findViewById(R.id.list);

        ArrayAdapter<String> ad = new ArrayAdapter<String>(this, R.layout.single_item_layout ,  desc);//desc your string array 
        listView.setAdapter(ad);

        listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                //do something on click
                dialog.dismiss();
            }
        });

        dialog.show();
    }   
   desc=null;
}

それだけです。
