6         <item name="android:windowContentOverlay">@null</item>

7     </style>

4.dialog类

 1 package com.jingle.progressdialog;

 2 

 3 import android.annotation.SuppressLint;

 4 import android.app.Dialog;

 5 import android.content.Context;

 6 import android.view.LayoutInflater;

 7 import android.view.View;

 8 import android.view.animation.Animation;

 9 import android.view.animation.AnimationUtils;

10 import android.widget.ImageView;

11 import android.widget.LinearLayout;

12 

13 @SuppressLint("InflateParams")

14 public class LoadingDialog {

15 

16     private LoadingDialog() {

17 

18     }

19 

20     private static Dialog mLoadingDialog = null;

21 

22     // 单例模式

23     public static Dialog getLoadingDialog(Context context, String msg) {

24 

25         LayoutInflater inflater = LayoutInflater.from(context);

26         View v = inflater.inflate(R.layout.dialog_loading, null);// 得到加载对话框的view

27         LinearLayout layout = (LinearLayout) v.findViewById(R.id.dialog_view);// 加载对话框布局

28 

29         ImageView spaceshipImage = (ImageView) v.findViewById(R.id.img);// 加载的图像

30         // TextView tipTextView = (TextView) v.findViewById(R.id.tipTextView);//

31         // 提示文字

32         // tipTextView.setText(msg);// 设置加载信息

33         // 加载动画

34         Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(

35                 context, R.anim.loading_animation);

36         // 使用ImageView显示动画

37         spaceshipImage.startAnimation(hyperspaceJumpAnimation);

38 

39         if (mLoadingDialog == null) {

40             mLoadingDialog = new Dialog(context, R.style.loading_dialog0);

41         }

42 

43         // Dialog loadingDialog = new Dialog(context, R.style.loading_dialog);//

44         // 创建自定义样式dialog

45 

46         // loadingDialog.setCancelable(false);// 不可以用“返回键”取消

47         mLoadingDialog.setContentView(layout, new LinearLayout.LayoutParams(

48                 LinearLayout.LayoutParams.MATCH_PARENT,

49                 LinearLayout.LayoutParams.MATCH_PARENT));// 设置布局

50         return mLoadingDialog;

51 

52     }

53 }

 

 

5.调用dialogMainActivity.java

 1 package com.jingle.progressdialog;

 2 

 3 import java.util.Timer;

 4 import java.util.TimerTask;

 5 

 6 import android.app.Activity;

 7 import android.app.Dialog;

 8 import android.os.Bundle;

 9 

10 public class MainActivity extends Activity {

11     private Dialog dialog = null;

12 

13     @Override

14     protected void onCreate(Bundle savedInstanceState) {

15         super.onCreate(savedInstanceState);

16         setContentView(R.layout.activity_main);

17 

18         initDialog();

19     }

20 

21     private void initDialog() {

22         dialog = LoadingDialog.getLoadingDialog(this, "");

23         dialog.show();

24         Timer timer = new Timer();

25         timer.schedule(new Task(), 3000);

26     }

27     

28     class Task extends TimerTask {

29         public void run() {

30             dialog.dismiss();//解散dialog

31         }        

32     }

33 

34 }
