        title.setTextSize(30);
        title.setBackgroundColor(Color.GRAY);

Answer 3

你有另一个选择，为你的对话框设计一个xml layout你如何在活动中调用它并将其调用

示例xml：

 <?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="215dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@drawable/custom_alert"
android:orientation="vertical" >

<TextView
    android:id="@+id/tv_header"
    android:layout_width="fill_parent"
    android:layout_height="26dp"
    android:gravity="center"
    android:text="@string/oops"
    android:textColor="#3f3f3f"
    android:textSize="15sp"
    android:textStyle="bold"
     />

<TextView
    android:id="@+id/tv_description"
    android:layout_width="fill_parent"
    android:layout_height="58dp"
    android:layout_below="@+id/tv_header"
    android:gravity="center"
    android:textColor="#747474"
    android:textSize="10sp"
    android:typeface="sans" />

<View
    android:id="@+id/separator"
    android:layout_width="fill_parent"
    android:layout_height="1dip"
    android:layout_above="@+id/tv_actionbtn"
    android:layout_centerVertical="true"
    android:background="#b8b8b8" />

<TextView
    android:id="@+id/tv_actionbtn"
    android:layout_width="fill_parent"
    android:layout_height="40dp"
    android:layout_below="@+id/tv_description"
    android:gravity="center"
    android:textColor="#d61820"
    android:textSize="15sp"
    android:typeface="sans" />

custom_alert背景布局：

<corners android:color="#FFFFFF" />

<solid android:color="#FFFFFF" />

<stroke
    android:width="3dip"
    android:color="#FFFFFF" />

<corners
    android:radius="20dip"
    android:color="#FFFFFF" />

<padding
    android:bottom="0dip"
    android:left="0dip"
    android:right="0dip"
    android:top="0dip" />

这是活动代码

dialog = new Dialog(Activity.this);
        dialog.setContentView(R.layout.customdialog);

        dialog.getWindow().setBackgroundDrawable(
                new ColorDrawable(android.graphics.Color.TRANSPARENT));
        txtHeader = (TextView) dialog.findViewById(R.id.requiredheader);
        txtDiscription = (TextView) dialog.findViewById(R.id.requireddescription;
        txtHeader.setText(getResources().getString(R.string.conneting_server));
        txtDiscription.setText(getResources().getString(R.string.logging_in));
        dialog.setCancelable(false);
        dialog.show();
