仅替换dialog.xml布局文件中的Textview:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:orientation="vertical" android:padding="5dp">
<TextView android:text="TextView" android:id="@+id/textView1"
android:layout_height="fill_parent" android:layout_width="fill_parent" />
<Button android:text="Button" android:id="@+id/button1"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:gravity="center" />
</LinearLayout>
<TextView android:text="TextView" android:id="@+id/textView1"
android:layout_height="wrap_content" android:layout_width="fill_parent" />
