Question

我有一个警觉组织,我只想在我点击“科索沃”之后开始下一次活动。问题在于我的方法,我有与我的意图相关的地方变量,我无法采用“仇恨”方法。

//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();

在<代码>showDialog(>之后,我是否可阻止该代码运行直至用户点击K? 我有地方的变数,我需要把意图放在内。

Answer 1

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

Answer 2

使用该守则

AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                         new ContextThemeWrapper(this, R.style.popup_theme));
    alertDialog.setTitle("Select Game");         
    alertDialog.setMessage("[ Choose Puzzle Matrix ]");      
    alertDialog.setPositiveButton("3x3", new DialogInterface.OnClickListener() {  
    public void onClick(DialogInterface dialog, int which) { 
        Intent myIntent = new Intent(((Dialog) dialog).getContext(), Matrix3x3.class);
        startActivity(myIntent);    
        return;  
        }        
    });      
    alertDialog.show();

Answer 3

Make students variable final.

final ArrayList<String> students = new ArrayList<String>();
