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;
}
}
