An encapsulated example of android programming implementation dialog box

This article illustrates the encapsulation of android programming dialog box. To share for your reference, the details are as follows:

/**
*  dialog 
*/
private static ProgressDialog mProgressDialog;
/**
*  The default dialog box 
*  Title, content, two buttons 
* @param context
* @param title
* @param content
* @param btnOKStr  Null characters   The button is not displayed  ( Pay special attention to )
* @param btnCancelStr  Null characters   The button is not displayed 
* @param onClick
*/
public static void showDefaultDialog(Context context,String title,String content,
   String btnOKStr,String btnCancelStr,OnClickListener onClick){
  showDefaultDialog(context, title, content, btnOKStr, btnCancelStr, onClick, null);
}
/**
*  The default dialog box  + cancel The event 
* @param context
* @param title
* @param content
* @param btnOKStr
* @param btnCancelStr
* @param onClick
* @param onCancel
*/
public static void showDefaultDialog(Context context,String title,String content,
   String btnOKStr,String btnCancelStr,
   OnClickListener onClick,OnCancelListener onCancel){
  AlertDialog.Builder mBuilder = new AlertDialog.Builder(context);
  if(title != null){
   mBuilder.setTitle(title);
  }
  mBuilder.setMessage(content);
  if(btnOKStr == null)
   btnOKStr = " determine ";
  if(btnCancelStr == null)
   btnCancelStr = " cancel ";
  if(!btnOKStr.trim().equals(""))
   mBuilder.setPositiveButton(btnOKStr, onClick);
  if(!btnCancelStr.trim().equals(""))
   mBuilder.setNegativeButton(btnCancelStr, onClick);
  if(onCancel != null){
   mBuilder.setOnCancelListener(onCancel);
  }
  mBuilder.show();
}
public static void showProgressDialog(Context context,String msg,boolean cancelable) {
//  dismissProgressDialog();
  mProgressDialog = new ProgressDialog(context);
  mProgressDialog.setMessage(msg);
  mProgressDialog.setCancelable(cancelable);
  mProgressDialog.show();
}
public static void dismissProgressDialog(){
  if (mProgressDialog != null && mProgressDialog.isShowing()) {
   mProgressDialog.dismiss();
   mProgressDialog = null;
  }
}
