自定义对话框

                                        <pre><code>AlertDialog.Builder builder = new AlertDialog.Builder(this);

Dialog dialog = builder.create();
// show函数需要在getwindow前调用
dialog.show();
// 对话框窗口设置布局文件
Window window = dialog.getwindow();
window.setContentView(R.layout.res);

// 获取对话窗口中的ListView
ListView list_record = (ListView) window.findViewById(R.id.someView);
