(3)MainActivity.java

package com.lxd.activity;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;

import com.lxd.widgets.CustomProgressDialog;
import com.lxd.widgets.CustomProgressDialogWithGif;

public class MainActivity extends Activity {
	
	private String TAG = getClass().getName();
	
//	private  CustomProgressDialogWithGif gifProgressDialog = null;
	private CustomProgressDialog imageProgressDialog = null;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉标题栏
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);//去掉信息栏
        
        setContentView(R.layout.main);
        
        
        
       View gifBtn = findViewById(R.id.gif_custom_preogeress_dialog_btn);
      
        
        gifBtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View arg0) {
				/**
				 * gif图片占用内存大，需要及时释放，这里到的时候就重新生成，对话框一关闭，自动调用
				 */
				CustomProgressDialogWithGif gifProgressDialog = new CustomProgressDialogWithGif(MainActivity.this , "正在加载中...");
				gifProgressDialog.show();
			}
		});
        
        
        View imageBtn = findViewById(R.id.image_custom_preogeress_dialog_btn);
        imageProgressDialog = CustomProgressDialog.createDialog(this);
        imageProgressDialog.setMessage("正在加载中...");
        imageBtn.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				imageProgressDialog.show();
			}
		});
        
    }
    

}

这里值得注意是gif图片加载要及时消毁，要用就new出来。

styles.xml

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

    <!-- 自定义弹窗的样式 -->
    <style name="CustomDialog" parent="@android:style/Theme.Dialog">
		<item name="android:windowFrame">@null</item>
    	<item name="android:windowIsFloating">true</item>
    	<item name="android:windowContentOverlay">@null</item>
    	<item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    	<item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
