DialogFragment是Android3.0引入的，也是谷歌官方推荐用来创建对话框的类。

DialogFragment相对与Dialog的最大优点是在手机配置变化，导致Activity需要重新创建时，例如旋屏，基于DialogFragment的对话框将会由FragmentManager自动重建，然而基于Dialog实现的对话框则会消失。

实现标题内容的代码如下，代码中已经标注了详细的注释:

import android.app.DialogFragment;import android.content.Context;import android.content.res.Configuration;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.view.Window;import android.widget.Button;import android.widget.RelativeLayout;public class FullScreenDialogFragment extends DialogFragment {@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {//去掉dialog的标题栏getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);View view = inflater.inflate(R.layout.fragment_layout, container,false);Button btn = (Button) view.findViewById(R.id.remind_right_button);btn.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {getDialog().dismiss();}});/** *通过屏幕方向来切换相应的图片 */RelativeLayout relativeLayout = (RelativeLayout) view.findViewById(R.id.bg_layout);if (!isScreenOriatationPortrait(getActivity())) {relativeLayout.setBackgroundResource(R.drawable.remind_dialog);}return view;}@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);//配置Dialog全屏setStyle(DialogFragment.STYLE_NORMAL,android.R.style.Theme_Black_NoTitleBar_Fullscreen);}/** * 判断屏幕是否是竖屏 * @param context * @return */public static boolean isScreenOriatationPortrait(Context context) {return context.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT;}}

R.layout.fragment_layout.xml

<?xml version="1.0" encoding="UTF-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/bg_layout"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:background="@drawable/remind_dialog_port" >    <Button        android:id="@+id/remind_right_button"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:layout_centerHorizontal="true"        android:layout_marginBottom="30dp"        android:text="确定"         /></RelativeLayout>

在Activity中调用:

FullScreenDialogFragment fullScreenDialogFragment = new FullScreenDialogFragment();fullScreenDialogFragment.show(getFragmentManager(), "FullScreenDialogFragment");
