自定义dialog，加载数据或网络请求时 dialog+动画（两种样式分享）

方式一：

效果图

package com.example.dialog;

import android.app.AlertDialog;

import android.app.Dialog;

import android.content.Context;

import android.view.Window;

public class ProgressBarUtils {

private static Dialog mDialog;

private static void initProgressBar(Context context) {

mDialog = new AlertDialog.Builder(context).create();

mDialog.setCanceledOnTouchOutside(false);

mDialog.show();

Window window = mDialog.getWindow();

window.setContentView(R.layout.progress_bar);

}

public static void showProgressBar(Context context) {

hideProgressBar();

initProgressBar(context);

}

public static void showProgressBar(Context context, String message) {

hideProgressBar();

showProgressBar(context);

}

public static void hideProgressBar() {

if (mDialog != null) {

mDialog.cancel();

mDialog = null;

}

}

}

xml文件：

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical"

>

<ProgressBar

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:indeterminateBehavior="repeat"

android:indeterminateDrawable="@drawable/progressbar_bg"

android:indeterminateOnly="true"

android:layout_centerInParent="true"/>

</RelativeLayout>

drawable下资源文件：

<?xml version="1.0" encoding="utf-8"?>

<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"

android:drawable="@drawable/progress_bar"

android:pivotX="50%"

android:pivotY="50%"

/>

代码 ：

package com.example.dialog;

import android.app.Dialog;

import android.content.Context;

import android.graphics.drawable.AnimationDrawable;

import android.graphics.drawable.Drawable;

import android.view.Gravity;

import android.view.View;

import android.widget.ImageView;

public class ShowProgressDialog extends Dialog {

private Context ctt=null;

private static ShowProgressDialog dialog;

public static ShowProgressDialog createDialog(Context context){

if (dialog == null) {

//dialog = new ShowProgressDialog(context);

dialog = new ShowProgressDialog(context,R.style.CustomProgressDialog);//这里 你可以自己定义一个

dialog.setContentView(R.layout.showprogressdialog);

dialog.setCancelable(false);//设置按back键不会取消

dialog.setCanceledOnTouchOutside(false);//设置窗体外部 不可触摸

dialog.getWindow().getAttributes().gravity = Gravity.CENTER;//显示在中间

dialog.onWindowFocusChanged(false);//关键

dialog.show();

return dialog;

}else {

return dialog;

}

}

@Override

public void onWindowFocusChanged(boolean hasFocus) {

// TODO Auto-generated method stub

super.onWindowFocusChanged(hasFocus);

if (dialog==null) {

return;

}else {

ImageView imageView = (ImageView) dialog.findViewById(R.id.loadingImageView);

AnimationDrawable ad= (AnimationDrawable) imageView.getDrawable(); //关键

ad.start();

}

}

//系统提供的 一个参数的

public ShowProgressDialog(Context context) {

super(context);

// TODO Auto-generated constructor stub

this.ctt = context;

}

//系统提供的 二个参数的

public ShowProgressDialog(Context context, int theme) {

super(context, theme);

// TODO Auto-generated constructor stub

this.ctt = context;

}

//系统提供 带三个参数的

protected ShowProgressDialog(Context context, boolean cancelable,

OnCancelListener cancelListener) {

super(context, cancelable, cancelListener);

// TODO Auto-generated constructor stub

this.ctt = context;

}

}

XML文件：

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent" >

<ImageView

android:id="@+id/loadingImageView"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerHorizontal="true"

android:layout_centerInParent="true"

android:src="@drawable/progress_round" />

</RelativeLayout>

drawable下 资源文件：

<?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/loading_01" android:duration="100"></item>

<item android:drawable="@drawable/loading_02" android:duration="100"></item>

<item android:drawable="@drawable/loading_03" android:duration="100"></item>

<item android:drawable="@drawable/loading_04" android:duration="100"></item>

<item android:drawable="@drawable/loading_05" android:duration="100"></item>

<item android:drawable="@drawable/loading_06" android:duration="100"></item>

<item android:drawable="@drawable/loading_07" android:duration="100"></item>

<item android:drawable="@drawable/loading_08" android:duration="100"></item>

</animation-list>

调用示例：

package com.example.dialog;

import android.os.Bundle;

import android.app.Activity;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Switch;

import android.widget.TextView;

public class MainActivity extends Activity implements GetContent{

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

hell=(TextView) findViewById(R.id.hell);

show_qishu=(TextView) findViewById(R.id.show_qishu);

show_beishu=(TextView) findViewById(R.id.show_beishu);

hell.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

//Mydialog.createDialog(MainActivity.this).show();

//自定义dialog示例1

//ShowProgressDialog dialog=ShowProgressDialog.createDialog(MainActivity.this);

//dialog.show(); //注意里面我是 封装了show()方法的

//自定义dialog示例 2

ProgressBarUtils.showProgressBar(MainActivity.this);

}

});

}

}
