Android 自訂progressDialog實現

先看下效果：

 

1.String.xml 檔案，progressDialog是繼承與Dialog，先設定一下progressDialog的風格，設定背景透明色。

<style name="CustomDialog" parent="@android:style/Theme.Dialog">     <item name="android:windowFrame">@null</item>         <item name="android:windowIsFloating">true</item>         <item name="android:windowContentOverlay">@null</item>         <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>         <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>     </style>            <style name="CustomProgressDialog" parent="@style/CustomDialog">         <item name="android:windowBackground">@android:color/transparent</item>         <item name="android:windowNoTitle">true</item>     </style>

2.customprogressdialog.xml檔案，定義自己的布局，由於我的需求只需要一個進度條以及一串顯示的內容，所以布局比較接單

<?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="fill_parent"   android:orientation="horizontal">     <ImageView         android:id="@+id/loadingImageView"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:background="@anim/progress_round"/>     <TextView         android:id="@+id/id_tv_loadingmsg"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center_vertical"         android:textSize="20dp"/> </LinearLayout>

3.progress_round.xml檔案.這個檔案為了實現轉動的效果，迴圈顯示這些圖片。

<?xml version="1.0" encoding="utf-8"?> <animation-list     xmlns:android="http://schemas.android.com/apk/res/android"     android:oneshot="false">     <item android:drawable="@drawable/progress_1" android:duration="200"/>     <item android:drawable="@drawable/progress_2" android:duration="200"/>     <item android:drawable="@drawable/progress_3" android:duration="200"/>     <item android:drawable="@drawable/progress_4" android:duration="200"/>     <item android:drawable="@drawable/progress_5" android:duration="200"/>     <item android:drawable="@drawable/progress_6" android:duration="200"/>     <item android:drawable="@drawable/progress_7" android:duration="200"/>     <item android:drawable="@drawable/progress_8" android:duration="200"/> </animation-list>

4.CustomProgressDialog.java檔案

package com.lxd.widgets;  import com.lxd.activity.R; import android.app.Dialog;import android.content.Context;import android.graphics.drawable.AnimationDrawable;import android.view.Gravity;import android.widget.ImageView;import android.widget.TextView;  /******************************************************************** * [Summary] *       TODO 請在此處簡要描述此類所實現的功能。因為這項注釋主要是為了在IDE環境中產生tip協助，務必簡明扼要 * [Remarks] *       TODO 請在此處詳細描述類的功能、調用方法、注意事項、以及與其它類的關係. *******************************************************************/ public class CustomProgressDialog extends Dialog {    private Context context = null;    private static CustomProgressDialog customProgressDialog = null;         public CustomProgressDialog(Context context){        super(context);        this.context = context;    }         public CustomProgressDialog(Context context, int theme) {        super(context, theme);    }         public static CustomProgressDialog createDialog(Context context){        customProgressDialog = new CustomProgressDialog(context,R.style.CustomProgressDialog);        customProgressDialog.setContentView(R.layout.customprogressdialog);        customProgressDialog.getWindow().getAttributes().gravity = Gravity.CENTER;                 return customProgressDialog;    }      public void onWindowFocusChanged(boolean hasFocus){                 if (customProgressDialog == null){            return;        }                 ImageView imageView = (ImageView) customProgressDialog.findViewById(R.id.loadingImageView);        AnimationDrawable animationDrawable = (AnimationDrawable) imageView.getBackground();        animationDrawable.start();    }      /**     *     * [Summary]     *       setTitile 標題     * @param strTitle     * @return     *     */    public CustomProgressDialog setTitile(String strTitle){        return customProgressDialog;    }         /**     *     * [Summary]     *       setMessage 提示內容     * @param strMessage     * @return     *     */    public CustomProgressDialog setMessage(String strMessage){        TextView tvMsg = (TextView)customProgressDialog.findViewById(R.id.id_tv_loadingmsg);                 if (tvMsg != null){            tvMsg.setText(strMessage);        }                 return customProgressDialog;    }}

5.調用

 CustomProgressDialog progressDialog = CustomProgressDialog.createDialog(this);
