【移动应用开发技术】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：packagecom.example.myprogressdialog_zzw;importandroid.app.Dialog;importandroid.content.Context;importandroid.graphics.drawable.AnimationDrawable;importandroid.view.Gravity;importandroid.view.View;importandroid.view.animation.Animation;importandroid.widget.ImageView;importandroid.widget.TextView;/**

*/publicclassMyProgressDialogextendsDialog{

privateContextcontext;

privatestaticMyProgressDialogmyProgressDialog=null;

publicMyProgressDialog(Contextcontext)

{

super(context);

this.context=context;

}

publicMyProgressDialog(Contextcontext,inttheme)

{

super(context,theme);

}

publicstaticMyProgressDialogcreateDialog(Contextcontext)

{

myProgressDialog=newMyProgressDialog(context,

R.style.myprogressDialog);

myProgressDialog.setContentView(R.layout.dialog_layout);

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

returnmyProgressDialog;

}

/*

*

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

*/

@Override

publicvoidonWindowFocusChanged(booleanhasFocus)

{

//TODOAuto-generatedmethodstub

super.onWindowFocusChanged(hasFocus);

ImageViewp_w_picpath_loadingp_w_picpath=(ImageView)myProgressDialog

.findViewById(R.id.p_w_picpath_loadingp_w_picpath);

AnimationDrawableanimation=(AnimationDrawable)p_w_picpath_loadingp_w_picpath

.getBackground();

animation.start();

}

publicMyProgressDialogsetTitle(StringstrTitle)

{

returnmyProgressDialog;

}

/**

*@paramstrMessage

*@return设置progressDialog的消息内容

*/

publicMyProgressDialogsetMessage(StringstrMessage)

{

TextViewtv_loadingmsg=(TextView)myProgressDialog

.findViewById(R.id.tv_loadingmsg);

if(tv_loadingmsg!=null)

{

tv_loadingmsg.setText(strMessage);

}

returnmyProgressDialog;

}}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：packagecom.example.myprogressdialog_zzw;importandroid.app.Activity;importandroid.os.Bundle;importandroid.os.Handler;importandroid.os.Message;importandroid.util.Log;importandroid.view.Menu;importandroid.view.View;importandroid.view.View.OnClickListener;importandroid.widget.Button;importandroid.widget.Toast;/**

*采用线程的的sleep模拟下载结束后关闭progressDialog

*/publicclassMainActivityextendsActivity{

MyProgressDialogmyProgressDialog=null;

Handlerhandler=newHandler()

{

publicvoidhandleMessage(Messagemsg)

{

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

protectedvoidonCreate(BundlesavedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

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

btn_go.setOnClickListener(newOnClickListener()

{

@Override

publicvoidonClick(Viewv)

{

if(myProgressDialog==null)

{

myProgressDialog=MyProgressDialog

.createDialog(MainActivity.this);

myProgressDialog.setMessage("努力加载中...");

}

myProgressDialog.show();

newThread()

{

@Override

{

Log.e("线程","进入线程！");

try

{

Thread.sleep(5000);

Messagemsg=newMessage();

msg.what=1;

handler.sendMessage(msg);

}

catch(InterruptedExceptione)
