Android自定义ProgressDialog

MainActivity如下:

package cn.testprogressdialog;

import android.app.Activity;

import android.app.Dialog;

import android.content.Context;

import android.content.DialogInterface;

import android.content.DialogInterface.OnCancelListener;

import android.os.Bundle;

import android.view.Window;

/**

 * Demo描述:

 * 自定义ProgressDialog

 * 

 * 备注说明:

 * 在此处progressDialog.setOnCancelListener(){}

 * 并没有起到按下back键盘使风火轮消失的作用.

 * 因为在initDialog(Context context)中设置了

 * dialog.setCancelable(false);

 * 若需要此功能,注释掉该句代码即可.

public class MainActivity extends Activity {

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);

		Dialog progressDialog=initDialog(MainActivity.this);

		progressDialog.setOnCancelListener(new OnCancelListener() {

			@Override

			public void onCancel(DialogInterface dialog) {

				dialog.dismiss();

				//其余业务逻辑

			}

		});

		progressDialog.show();

	}



	public Dialog initDialog(Context context) {

		Dialog dialog = new DialogSubClass(MainActivity.this, R.style.dialog);

		dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

		dialog.setCanceledOnTouchOutside(false);

		dialog.setCancelable(false);

		return dialog;

	}



}

	}



	protected DialogSubClass(Context context, boolean cancelable,OnCancelListener cancelListener) {

		super(context, cancelable, cancelListener);

	}



	public DialogSubClass(Context context) {

		super(context);

	}

	

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		View view = LayoutInflater.from(getContext()).inflate(R.layout.dialoglayout, null);

		setContentView(view);

	}

	

	@Override

	public void show() {

		super.show();

	}

	

	@Override

	public void dismiss() {
