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);

}
});
}
