如何用户单击确定在AlertDialog之后才开始活动 [英] How to start activity only after user clicks ok on AlertDialog

问题描述

我有一个AlertDialog，我只希望接下来的活动开始后，我点击确定。现在的问题是在我的方法，我有局部变量连接到我的意图，我不能把在onCreateDialog方法。

I have an AlertDialog and I only want the next Activity to start after I have click "OK". The problem is in my method, I have local variables attached to my intent and I cannot put in the onCreateDialog method.

//local variable created
ArrayList<String> students = new ArrayList<String>();    
for(int i=0; i<studentList.size(); i++){
    students.add(studentList.get(i).getName());
}

AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                     new ContextThemeWrapper(this, R.style.popup_theme));
alertDialog.setTitle("Select Game");           
alertDialog.setPositiveButton("3x3", new DialogInterface.OnClickListener() {  
public void onClick(DialogInterface dialog, int which) { 

    //I want the new Activity to start only after user clicks ok.
    Intent intent=new Intent(getApplicationContext(),NewActivity.class);
    //Local variable, undefined, cannot reference 
    intent.putStringArrayListExtra("students", students);
    startActivity(intent);
    finish();
    return;  
    }        
}); 
alertDialog.show();

有没有什么办法可以prevent后的ShowDialog的code（）运行，直到用户点击OK？我有我需要把里面的意图局部变量。

Is there any way I can prevent the code after showDialog() from running until the user clicks OK? I have local variable that I need to put inside the intent.

推荐答案

不知道这是否是一个正确的做法，但我做了一个'黑客'通过学生全球变量。欢迎更好的答案。

Not sure if this is a right way but I did a 'hack' by making students a global variable. Would welcome better answers.
