一位從vb系轉到JAVA的朋友在一個類中寫了一個類似VB中MSGBOX的方法

//此方法放一個自定義的JAVA類中

public static boolean msgBoxPlus(Activity objPage, String strTitle,String strMsg,String strOkTitle,String strCancelTitle){

if(strOkTitle==""){
strOkTitle="Ok";
}
if(strCancelTitle==""){
strCancelTitle="Cancel";
}



AlertDialog.Builder dtl= new AlertDialog.Builder(objPage);



dtl.setTitle(strTitle);//���öԻ������

dtl.setMessage(strMsg);//������ʾ������

final TextView txtNote=new TextView(objPage);
dtl.setView(txtNote);

dtl.setPositiveButton(strOkTitle,new DialogInterface.OnClickListener() {//���ȷ����ť

@Override

public void onClick(DialogInterface dialog, int which) {//ȷ����ť����Ӧ�¼�

// TODO Auto-generated method stub
txtNote.setText("true");
//finish();

}

});

DialogInterface.OnClickListener dtlclc=new DialogInterface.OnClickListener(){

@Override

public void onClick(DialogInterface dialog, int which) {//��Ӧ�¼�

// TODO Auto-generated method stub
txtNote.setText("false");
//Log.i("alertdialog"," �뱣����ݣ�");
//finish();

}


};

dtl.setNegativeButton(strCancelTitle,dtlclc);


dtl.show();//�ڰ�����Ӧ�¼�����ʾ�˶Ի���

String strOk=txtNote.getText().toString();
if(strOk=="true"){
return true;
}else{
return false;
}

}
