1、首先准备好图片资源，写一个自定义的drawable（progress\_drawable\_white），实现动画功能。

<?xml version="1.0" encoding="utf-8"?>
    <animation-list android:oneshot="false"
                    xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_01" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_02" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_03" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_04" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_05" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_06" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_07" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_08" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_09" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_10" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_11" />
        <item android:duration="83" android:drawable="@drawable/ic_loading_white_12" />
    </animation-list>

2、布局文件是少不了的，接着。。。（dialog\_my）

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:background="@drawable/ic_loading_bg"
                  android:gravity="center"
                  android:orientation="vertical"
                  android:padding="16.0dip" >
    
        <ProgressBar
                android:layout_width="30.0dip"
                android:layout_height="30.0dip"
                android:indeterminateDrawable="@drawable/progress_drawable_white" />
    
        <TextView
                android:id="@+id/id_tv_loadingmsg"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_vertical"
                android:layout_marginTop="8.0dip"
                android:textColor="#fff"
                android:textSize="16.0dip" />
    
    </LinearLayout>

3、res包下values包需要之定义style（style\_dialog）

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <style name="progress_dialog" parent="@android:style/Theme.Dialog">
            <item name="android:windowFrame">@null</item>
            <item name="android:windowIsFloating">true</item>
            <item name="android:windowIsTranslucent">true</item>
            <item name="android:windowNoTitle">true</item>
            <item name="android:background">@null</item>
            <item name="android:windowBackground">@null</item>
            <item name="android:backgroundDimEnabled">false</item>
        </style>
    </resources>

4、BaseActivity中书写公共的方法，以后项目中所有的Activity只要继承BaseActivity，只需调用方法就行了。加载提示的内容我写了两种，可以这样用，十分方便。

package com.sunday.myprogresdialog;
    
    import android.app.Activity;
    import android.app.Dialog;
    import android.os.Bundle;
    import android.widget.TextView;
    
    public class BaseActivity extends Activity {
    	private Dialog progressDialog;
    
    	/**
    	 * Called when the activity is first created.
    	 */
    	@Override
    	public void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    	}
    
    	/**
    	 * 
    	 * @Description: TODO 自定义加载提示内容
    	 * @param @param id
    	 * @return void 用法buildProgressDialog(R.string.loding)
    	 * @throws
    	 * @author Sunday
    	 * @date 2015年12月25日
    	 */
    	public void buildProgressDialog(int id) {
    		if (progressDialog == null) {
    			progressDialog = new Dialog(this, R.style.progress_dialog);
    		}
    		progressDialog.setContentView(R.layout.dialog_my);
    		progressDialog.setCancelable(true);
    		progressDialog.getWindow().setBackgroundDrawableResource(
    				android.R.color.transparent);
    		TextView msg = (TextView) progressDialog
    				.findViewById(R.id.id_tv_loadingmsg);
    		msg.setText(getString(id));
    		progressDialog.show();
    	}
    
    	/**
    	 * @Description: TODO 固定加载提示内容
    	 * @author Sunday
    	 */
    	public void buildProgressDialog() {
    		if (progressDialog == null) {
    			progressDialog = new Dialog(this, R.style.progress_dialog);
    		}
    		progressDialog.setContentView(R.layout.dialog_my);
    		progressDialog.setCancelable(true);
    		progressDialog.getWindow().setBackgroundDrawableResource(
    				android.R.color.transparent);
    		TextView msg = (TextView) progressDialog
    				.findViewById(R.id.id_tv_loadingmsg);
    		msg.setText("卖力加载中");
    		progressDialog.show();
    	}
    
    	/**
    	 * @Description: TODO 取消加载框
    	 * @author Sunday
    	 * @date 2015年12月25日
    	 */
    	public void cancelProgressDialog() {
    		if (progressDialog != null) {
    			progressDialog.dismiss();
    		}
    	}
    }

5、只需调用buildProgressDialog()和cancelProgressDialog()就能实现加载和取消了。
