尝试在
Android中显示对话框时出现异常.我的AlertDialog是从FragmentActivity调用的,代码如下:
@H_403_13@解决方法
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;
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);
