android - 删除对话框列表底部的空格

Question

当你打开对话框窗口时，我有它，在 Eclipse 中的 DumpView 层次结构中，5 个选项下面有这个空白...它说它是 (2) FrameLayout [34,894][686,1022]。

我的代码是:

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
                    builder.setTitle(R.string.sync_frequency);
                    ListView listView = new ListView(getActivity());
                    String[] syncOptions = mSyncOptions;
                    ArrayAdapter<String> modeAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.select_dialog_singlechoice, android.R.id.text1, syncOptions);
                    builder.setSingleChoiceItems(modeAdapter, 0, new DialogInterface.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.dismiss();
                            int selectedPosition = ((AlertDialog)dialog).getListView().getCheckedItemPosition();
                            Log.d(TAG, "Position is " + selectedPosition);

                        }
                    });
                    builder.setView(listView);
                    builder.setNegativeButton(R.string.sync_cancel,null);
                    final Dialog dialog = builder.create();
                    dialog.getWindow().setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
                    dialog.show();

我正在尝试摆脱那里的空白...我不确定如何摆脱它...我什至尝试过 dialog.getWindow().setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

但它并没有切断空间。我猜是因为它将它视为一个框架布局而不是空白区域。谢谢!

您是否尝试过将布局参数设置为 listView(在展开为对话框之前)？

ListView listView = new ListView(getActivity());
listView.setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
.
.
.
builder.setView(listView);

另一种选择是不在对话框上使用 setView，而是使用 setAdapter()，如下例所示:

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setTitle(R.string.sync_frequency);
    ListView listView = new ListView(getActivity());
    String[] syncOptions = mSyncOptions;
    ArrayAdapter<String> modeAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.select_dialog_singlechoice, android.R.id.text1, syncOptions);
    builder.setAdapter(modeAdapter, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });
    builder.setNegativeButton(R.string.sync_cancel,null);
    final Dialog dialog = builder.create();
    dialog.show();
