android 自定义progressdialog,自定义ProgressDialog

最近工作中需要用到progressDialog，可是系统自带的黑色progressDialog又是其丑无比，无奈只能自己自定义了，在网上查看别人的例子，并自己整理了一份Demo：

先上图：

MyProgressDialog：

package com.example.myprogressdialog_zzw;

import android.app.Dialog;

import android.content.Context;

import android.graphics.drawable.AnimationDrawable;

import android.view.Gravity;

import android.view.View;

import android.view.animation.Animation;

import android.widget.ImageView;

import android.widget.TextView;

/**

*

*/

public class MyProgressDialog extends Dialog

{

private Context context;

private static MyProgressDialog myProgressDialog = null;

public MyProgressDialog(Context context)

{

super(context);

this.context = context;

}

public MyProgressDialog(Context context, int theme)

{

super(context, theme);

}

public static MyProgressDialog createDialog(Context context)

{

myProgressDialog = new MyProgressDialog(context,

R.style.myprogressDialog);

myProgressDialog.setContentView(R.layout.dialog_layout);

myProgressDialog.getWindow().getAttributes().gravity = Gravity.CENTER;

return myProgressDialog;

}

/*

* (non-Javadoc)

*

* @see android.app.Dialog#onWindowFocusChanged(boolean) 设置动画

*/

@Override

public void onWindowFocusChanged(boolean hasFocus)

{

// TODO Auto-generated method stub

super.onWindowFocusChanged(hasFocus);

ImageView p_w_picpath_loadingp_w_picpath = (ImageView) myProgressDialog

.findViewById(R.id.p_w_picpath_loadingp_w_picpath);

AnimationDrawable animation = (AnimationDrawable) p_w_picpath_loadingp_w_picpath

.getBackground();

animation.start();

}

public MyProgressDialog setTitle(String strTitle)

{

return myProgressDialog;

}

/**

* @param strMessage

* @return 设置progressDialog的消息内容

*/

public MyProgressDialog setMessage(String strMessage)

{

TextView tv_loadingmsg = (TextView) myProgressDialog

.findViewById(R.id.tv_loadingmsg);

if (tv_loadingmsg != null)

{

tv_loadingmsg.setText(strMessage);

}

return myProgressDialog;

}

}

在MainActivity中对MyProgressDialog进行调用，为了模仿网络访问结束后，关闭ProgressDialog的过程，采用了线程的sleep，运行5秒后关闭ProgressDialog，上代码：

package com.example.myprogressdialog_zzw;

import android.app.Activity;

import android.os.Bundle;

import android.os.Handler;

import android.os.Message;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.Toast;

/**

* @author 鹭岛猥琐男

* 采用线程的的sleep模拟下载结束后关闭progressDialog

*

*/

public class MainActivity extends Activity

{

MyProgressDialog myProgressDialog = null;

Handler handler = new Handler()

{

public void handleMessage(Message msg)

{

if (msg.what == 1)

{

Log.e(“接收到消息”, “” + msg.what);

if (myProgressDialog != null)

{

myProgressDialog.dismiss();

myProgressDialog = null;

}

Toast.makeText(MainActivity.this, “加载完成！”, Toast.LENGTH_SHORT)

.show();

}

};

};

@Override

protected void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button btn_go = (Button) findViewById(R.id.button1);

btn_go.setOnClickListener(new OnClickListener()

{

@Override

public void onClick(View v)

{

if (myProgressDialog == null)

{

myProgressDialog = MyProgressDialog

.createDialog(MainActivity.this);

myProgressDialog.setMessage(“努力加载中…”);

}

myProgressDialog.show();

new Thread()

{

@Override

public void run()

{

Log.e(“线程”, “进入线程！”);

try

{

Thread.sleep(5000);

Message msg = new Message();

msg.what = 1;

handler.sendMessage(msg);

}

catch (InterruptedException e)

{

Log.e(“异常”, “失败！异常”);

}

}

}.start();

}

});

}

@Override

public boolean onCreateOptionsMenu(Menu menu)

{

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

}
