警告对话框与多行标题

AlertDialog.Builder 的 setCustomTitle() 方法可以指定要用于对话框标题的任意视图。这种方法的一个常见的用途是建立具有长标题的警告对话框。

AlertDialog.Builder builder = new AlertDialog.Builder(context, Theme_Material_Light_Dialog);
builder.setCustomTitle(inflate(context, R.layout.my_dialog_title, null))
       .setView(inflate(context, R.layout.my_dialog, null))
       .setPositiveButton("OK", null);

Dialog dialog = builder.create();
dialog.show();

my_dialog_title.xml;

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:padding="16dp">

    <TextView
        style="@android:style/TextAppearance.Small"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur
tincidunt condimentum tristique. Vestibulum ante ante, pretium porttitor

        android:textStyle="bold"/>
