public static voID displayShare(){    // show share options    CharSequence selections[] = new CharSequence[] {"Email","SMS","Tweet","Phone Call","Cancel"};    final AlertDialog.Builder builder = new AlertDialog.Builder(CommonVariables.mContext);    builder.setTitle("Share your location via...");    builder.setItems(selections,new DialogInterface.OnClickListener() {        @OverrIDe        public voID onClick(DialogInterface dialog,int which) {            switch(which){                case 0: // Email                   callEmailMethod();                    break;                case 1: // SMS                    callSMSMethod();                    break;                case 2: // Tweet                    callTwitterMethod();                    break;                case 3: // Phone Call                    callNumberMethod();                    break;                case 4:                    dialog.cancel();                    break;            }        }    });    builder.show();}

在以下行收到以下错误：builder.show();

我已经尝试了一切(除了正确的解决方案,似乎).任何帮助表示赞赏,谢谢.

注意：CommonVariables.mContext是FragmentActivity的上下文,不是null：CommonVariables.mContext = FragmentAct.this;

解决方法 问题是我的项目缺少AlertDialog的样式资源：

在styles.xml中放这个：

<style name="MyDialogtheme" parent="theme.AppCompat.light.Dialog.Alert" />

在您创建Alert Dialog的代码中输入：

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(),R.style.MyDialogtheme);
