Android 自定义加载框dialog

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. */@Overridepublic 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。
