推荐答案

您可以这样设置自定义标题

You can just set custom title like this

LayoutInflater inflater = this.getLayoutInflater();

    View titleView = inflater.inflate(R.layout.custom_title, null);

    new AlertDialog.Builder(SubCategoryActivity.this)
                        .setCustomTitle(titleView);

并且在custom_title布局中，您可以创建这样的自定义标题

and in custom_title layout you can create custom title like this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:id="@+id/llsubhead"
        android:background="@color/colorPrimary">

        <TextView
            android:id="@+id/exemptionSubHeading4"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:layout_marginBottom="10dp"
            android:layout_weight="1"
            android:text="Exemption Sub Head"
            android:textAppearance="@style/Base.TextAppearance.AppCompat.Medium"
            android:textColor="@color/white" />
    </LinearLayout>
</LinearLayout>
