创建XML文件dialog_layout_pro.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
    android:background="#dedede" 
    > 
    <TextView 
android:id="@+id/tv_dialog" 
android:layout_margin="30dip" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_centerHorizontal="true" 
android:layout_centerVertical="true" 
android:gravity="center" 
android:textColor="#444444" 
android:text="Please wait..." 
android:textSize="30sp" /> 
</RelativeLayout> 

和Java类

{ 

Dialog cusDialog; 
cusDialog = new Dialog(MyTestClass.this, R.style.CustomDialog); 
cusDialog.setContentView(R.layout.dialog_layout_pro); 
    TextView text = (TextView) cusDialog.findViewById(R.id.tv_dialog); 
    text.setText("here your counter value"); 

cusDialog.setCancelable(false); 
cusDialog.show(); 
}
