Question

插入自定义列表视图时出现错误Android SlidingDrawer按下列表视图上的按钮。但是，如果使用相同的源，则可以使用片段。这是为什么？

这是SlidingDrawer XML。

<SlidingDrawer
    android:id="@+id/slidingDraw"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:content="@+id/content"
    android:handle="@+id/handle"
    android:visibility="visible">

    <Button
        android:id="@+id/handle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Memo Check"/>

    <LinearLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:orientation="vertical"
        android:background="#ffffff">

        <ListView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/listView2">
        </ListView>
    </LinearLayout>

</SlidingDrawer>

这是listview自定义适配器

public View getView(final int position, View convertView, ViewGroup parent) {
    cursor.moveToPosition(position);

    if(convertView==null){
        convertView = inflater.inflate(item_layout,null);
    }
    Button btn = (Button)convertView.findViewById(R.id.Okbtn);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            cursor.moveToPosition(position);
            dialogView = (View) inflater.inflate(R.layout.memo_layout, null);
            TextView tv = (TextView) dialogView.findViewById(R.id.textView9);
            tv.setText(cursor.getString(cursor.getColumnIndex("_memo")));

            AlertDialog.Builder dlg = new AlertDialog.Builder(context);
            dlg.setTitle("Memo Check");
            dlg.setView(dialogView);
            dlg.setPositiveButton("OK", null);
            dlg.show();
        }
    });

    TextView tv1 = (TextView)convertView.findViewById(R.id.textView7);
    tv1.setText(cursor.getString(cursor.getColumnIndex("_date")));

    TextView tv2 = (TextView)convertView.findViewById(R.id.textView8);
    tv2.setText(cursor.getString(cursor.getColumnIndex("_time")));

    return convertView;
}

这是错误代码。

myAdapter2.java:72是listview自定义适配器的dlg.show（）。
