我有两个按钮,保存和解除,并且都调用是/否对话,一个显示“你想保存”,另一个显示“关闭更改？”.

我认为我的程序非常“脏”但我想它可以工作,但我的问题是“查看视图”变量,我不知道如何将它从Activity传递给Dialog,所以我可以用它来回忆启动Dialog的功能.

提前致谢,

我活动的.java(片段)

public void open_HH_Fragment_YesNo(View view,String aux_title,String aux_function)
{
    Bundle bundle=new Bundle();
    bundle.putString("setMessage",aux_title);
    bundle.putString("callingFunction",aux_function);

    DialogFragment newFragment = new HH_Fragment_YesNo();
    newFragment.setArguments(bundle);
    newFragment.show(getSupportFragmentManager(),"HH_Fragment_YesNo");
}

public void SaveChanges(View view,String aux_YesNo)
{
    if (aux_YesNo == "")
    {
        Toast.makeText(this,"Save changes?",Toast.LENGTH_SHORT).show();

我的对话的.java(完整)

    builder
        .setMessage(setMessage)                                             // R.string.dialog_fire_missiles
        .setPositiveButton("Sí",new DialogInterface.OnClickListener()      // R.string.fire
        {
            public void onClick(DialogInterface dialog,int id)
            {
                // Exit without saving
                mListener.onDialogPositiveClick(HH_Fragment_YesNo.this,view,callingFunction);
            }
        })

                mListener.onDialogNegativeClick(HH_Fragment_YesNo.this,callingFunction);
            }
        });

    // Create the AlertDialog object and return it
    return builder.create();
}
