Question

我使用3个按钮构建AlertBox（positiv，neutral和amp; negativ）：

myDialogBox = AlertDialog.Builder(context, R.style.MyAlertDialogTheme);

然后我像这样设置按钮：

myDialogBox.setPositiveButton(sBuyAtlas, new alogInterface.OnClickListener() 
myDialogBox.setNeutralButton(sBuyAtlas, new alogInterface.OnClickListener() 
myDialogBox.setNegativeButton(sBuyAtlas, new alogInterface.OnClickListener()

在运行时订单是积极 - 否定 - 中立

如何实现取消才是正确的。通常，＆＃34;取消＆＃34;是在对话框的严格的一面。我怎么能这样做，而不会错过中立作为取消？

Answer 1

您可以删除所有按钮，然后按照首选顺序重新添加

 AlertDialog alerDialog = new AlertDialog.Builder().build();
    Button posBtn = (Button) alertDialog.findViewById(android.R.id.button1);
    Button negBtn = (Button) alertDialog.findViewById(android.R.id.button2);
    Button neuBtn = (Button) alertDialog.findViewById(android.R.id.button3);

    //get parent ViewGroup
     ViewGroup parentLayout = (ViewGroup) posBtn.getParent();

    //get child indexes
    int posIndex = parentLayout.indexOfChild(posBtn);
    int negindex = parentLayout.indexOfChild(negBtn);
    int neuIndex = parentLayout.indexOfChild(neuBtn);

     parentLayout.removeAllViews();
     parentLayout.addView(neuIndex,posBtn); //< --- swapping neutral and positive
     parentLayout.addView(posIndex,neuBtn);
     parentLayout.addView(negIndex,negBtn);

如果您尝试在此处设置自定义对话框，则@Ranjan答案也应该同时工作是系统dailog克隆布局，只需操作按钮并根据您的要求对其进行排序，并将其设置为警报对话框视图。

将视图设置回警告对话框

LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.alert_dialog, null);
myDialogBox.setView(dialogView);

AlertDialog中的按钮顺序
