自定义Progress

一、先定义XML文件

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <LinearLayout
        android:layout_width="140dp"
        android:layout_height="140dp"
        android:layout_gravity="center"
        android:background="@drawable/progress_bg"
        android:gravity="center"
        android:orientation="vertical" >

        <ImageView
            android:id="@+id/progress_view"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:src="@drawable/netload_01" />

        <TextView
            android:id="@+id/progress_message"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:textColor="#f5f5f5"
            android:textSize="16dp" />
    </LinearLayout>

</FrameLayout>

二、设置progress的背景

progress_bg.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#9c000000" />

    <corners
        android:bottomLeftRadius="3dp"
        android:bottomRightRadius="3dp"
        android:topLeftRadius="3dp"
        android:topRightRadius="3dp" />
            
</shape>
   

三、自定义progress代码：

package com.changewei.testvolleyandimageloader;

import android.app.Dialog;
import android.content.Context;
import android.graphics.drawable.AnimationDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

public class MyProgressDialog {
	
	public Dialog mDialog;
	private AnimationDrawable animationDrawable = null;
	
	public MyProgressDialog(Context context, String message) {
		
		LayoutInflater inflater = LayoutInflater.from(context);
		View view = inflater.inflate(R.layout.progress_view, null);

		TextView text = (TextView) view.findViewById(R.id.progress_message);
		text.setText(message);
		ImageView loadingImage = (ImageView) view.findViewById(R.id.progress_view);
		loadingImage.setImageResource(R.anim.loading_animation);
		animationDrawable = (AnimationDrawable)loadingImage.getDrawable();
        if(animationDrawable!=null){
            animationDrawable.setOneShot(false);
            animationDrawable.start();
        }

		mDialog = new Dialog(context, R.style.dialog);
		mDialog.setContentView(view);
		mDialog.setCanceledOnTouchOutside(false);
		
	}
	
	public void show() {
		mDialog.show();
	}
	
	public void setCanceledOnTouchOutside(boolean cancel) {
		mDialog.setCanceledOnTouchOutside(cancel);
	}
	
	public void dismiss() {
		if(mDialog.isShowing()) {
			mDialog.dismiss();
			animationDrawable.stop();
		}
	}
    public boolean isShowing(){
        if(mDialog.isShowing()) {
            return true;
        }
        return false;
    }
}

四、progress动画loading_animation.xml：

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/netload_01" android:duration="50"></item>
    <item android:drawable="@drawable/netload_02" android:duration="50"></item>
    <item android:drawable="@drawable/netload_03" android:duration="50"></item>
    <item android:drawable="@drawable/netload_04" android:duration="50"></item>
    <item android:drawable="@drawable/netload_05" android:duration="50"></item>
    <item android:drawable="@drawable/netload_06" android:duration="50"></item>
    <item android:drawable="@drawable/netload_07" android:duration="50"></item>
    <item android:drawable="@drawable/netload_08" android:duration="50"></item>
    <item android:drawable="@drawable/netload_09" android:duration="50"></item>
    <item android:drawable="@drawable/netload_10" android:duration="50"></item>
    <item android:drawable="@drawable/netload_11" android:duration="50"></item>
    <item android:drawable="@drawable/netload_12" android:duration="50"></item>
</animation-list>

五、dialog的样式：

 <style name="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">@android:color/transparent</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:backgroundDimEnabled">true</item>
        <item name="android:backgroundDimAmount">0.6</item>
 	</style>

完成了，自定义的progress
