loadingDialog

1.dialog布局 dialog_loading.xml

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/dialog_view"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:background="@drawable/bg"
     android:gravity="center"
     android:minHeight="60dp"
     android:minWidth="180dp"
     android:orientation="vertical"
     android:padding="10dp" >

     <ImageView
         android:id="@+id/img"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:src="@drawable/base_loading_large_icon" />
 <!--
     <TextView
         android:gravity="center"
         android:id="@+id/tipTextView"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_marginLeft="10dp" />
 -->
 </LinearLayout>

2.图像的旋转动画 loading_animation.xml

 <?xml version="1.0" encoding="utf-8"?>
 <set android:shareInterpolator="false" xmlns:android="http://schemas.android.com/apk/res/android">
     <rotate
         android:interpolator="@android:anim/linear_interpolator"
         android:pivotX="50%"
         android:pivotY="50%"
         android:fromDegrees="0"
         android:toDegrees="+360"
         android:duration="1500"
         android:startOffset="-1"
         android:repeatMode="restart"
         android:repeatCount="-1"/>
 </set>

3.dialog的style

  <!-- 自定义loading dialog -->
     <style name="loading_dialog" parent="android:style/Theme.Dialog">
         <item name="android:windowFrame">@null</item>
         <item name="android:windowNoTitle">true</item>
         <item name="android:windowIsFloating">true</item>
         <item name="android:windowContentOverlay">@null</item>
     </style>

4.dialog类

 package com.jingle.progressdialog;

 import android.annotation.SuppressLint;
 import android.app.Dialog;
 import android.content.Context;
 import android.view.LayoutInflater;
 import android.view.View;
 import android.view.animation.Animation;
 import android.view.animation.AnimationUtils;
 import android.widget.ImageView;
 import android.widget.LinearLayout;

 @SuppressLint("InflateParams")
 public class LoadingDialog {

     private LoadingDialog() {

     }

     private static Dialog mLoadingDialog = null;

     // 单例模式
     public static Dialog getLoadingDialog(Context context, String msg) {

         LayoutInflater inflater = LayoutInflater.from(context);
         View v = inflater.inflate(R.layout.dialog_loading, null);// 得到加载对话框的view
         LinearLayout layout = (LinearLayout) v.findViewById(R.id.dialog_view);// 加载对话框布局

         ImageView spaceshipImage = (ImageView) v.findViewById(R.id.img);// 加载的图像
         // TextView tipTextView = (TextView) v.findViewById(R.id.tipTextView);//
         // 提示文字
         // tipTextView.setText(msg);// 设置加载信息
         // 加载动画
         Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(
                 context, R.anim.loading_animation);
         // 使用ImageView显示动画
         spaceshipImage.startAnimation(hyperspaceJumpAnimation);

         if (mLoadingDialog == null) {
             mLoadingDialog = new Dialog(context, R.style.loading_dialog0);
         }

         // Dialog loadingDialog = new Dialog(context, R.style.loading_dialog);//
         // 创建自定义样式dialog

         // loadingDialog.setCancelable(false);// 不可以用“返回键”取消
         mLoadingDialog.setContentView(layout, new LinearLayout.LayoutParams(
                 LinearLayout.LayoutParams.MATCH_PARENT,
                 LinearLayout.LayoutParams.MATCH_PARENT));// 设置布局
         return mLoadingDialog;

     }
 }

 

5.调用dialogMainActivity.java

 package com.jingle.progressdialog;

 import java.util.Timer;
 import java.util.TimerTask;

 import android.app.Activity;
 import android.app.Dialog;
 import android.os.Bundle;

 public class MainActivity extends Activity {
     private Dialog dialog = null;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);

         initDialog();
     }

     private void initDialog() {
         dialog = LoadingDialog.getLoadingDialog(this, "");
         dialog.show();
         Timer timer = new Timer();
         timer.schedule(new Task(), 3000);
     }

     class Task extends TimerTask {
         public void run() {
             dialog.dismiss();//解散dialog
         }
     }

 }
