我有一个场景,当我点击Button我想要AlertDialog弹出.AlertDialog是自定义警报对话框,因为它具有自定义Listview.

我使用以下代码分配AlertDialog OnClick按钮

 top.setOnClickListener(new OnClickListener() {
 Context mcontext;
 @Override
 public void onClick(View arg0) {
 // TODO Auto-generated method stub
 LayoutInflater li = LayoutInflater.from(getActivity());
 View view= li.inflate(R.layout.topingslist, null);

 AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getActivity());
 alertDialogBuilder.setView(view);
 ListView lv2 = (ListView) getActivity().findViewById(R.id.toplist);
 ArrayList<SearchResultsToping> results1 = new ArrayList<SearchResultsToping>();
 SearchResultsToping sr1;                                               
 sr1 = new SearchResultsToping();
 sr1.setToppingname("cheese");
 results1.add(sr1);
 MyCustomBaseAdapterTop arrayAdapter=new MyCustomBaseAdapterTop(getActivity(), results1);
 lv2.setAdapter(arrayAdapter);
 lv2.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,long arg3) { …

我正在使用按钮动态加载 gridview。因此，为此我使用了滚动视图，但是如果我将 wrap_content 作为高度分配给 gridview，则不会显示所有按钮。我不想为 gridview 分配任何静态高度。这是我正在使用的代码：

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

              <LinearLayout
                  android:layout_width="fill_parent"
                  android:layout_height="fill_parent"
                  android:orientation="vertical"
                  android:paddingLeft="5dip"
                  android:paddingRight="5dip" >

                  <GridView
                      android:id="@+id/gridviewtable"
                      android:layout_width="fill_parent"
                      android:layout_height=wrap_content"
                      android:horizontalSpacing="10dp"
                      android:numColumns="4"
                      android:verticalSpacing="10dp" >
                  </GridView>

              </LinearLayout>
          </ScrollView>
