Question

在我的应用程序中，当我关闭警报对话框然后获取错误java.lang.IllegalStateException。我点击肯定按钮打开对话框片段。但每次都会导致错误。

FATAL EXCEPTION: main
Process: com.icanstudioz.android.njoyful, PID: 18564
java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

我的代码就在这里，

final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
                builder.setTitle("Select").setView(np);
                builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        currentItem.setItemQuantity(String
                                .valueOf(np.getValue()));
                        v.setSelected(true);
                        if (currentItem.getModifier_group()
                                .length() == 0) {
                            NjoyApplication
                                    .getInstance()
                                    .addNewItemWithModifiers(
                                            currentItem, "0", false);
                            updateCart();
                        } else {
                            DialogFragment dialogFrag = new selectModifier();
                            Bundle b = new Bundle();
                            b.putString("ID", currentItem.getId()
                                    + "");
                            dialogFrag.setArguments(b);
                            dialogFrag.setTargetFragment(
                                    Create_Order_ListFragment.this,
                                    Modifier.SELECT_NEW_MODIFIER);
                            b.putInt("REQUEST_CODE",
                                    Modifier.SELECT_NEW_MODIFIER);
                            dialogFrag.setCancelable(true);
                            dialogFrag.show(getFragmentManager(),
                                    "dialog");
                        }
                    }
                }).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        v.setSelected(false);
                        dialog.dismiss();
                    }
                }).show();

见createview（），

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    return inflater.inflate(R.layout.common_gridview, container,false);
}

Answer 1

1. if you are using fragment than make sure,

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view=inflater.inflate(R.layout.fragment_reject, container,false);
    return view;
    }
in above code there should be **false** after container.


2. you must set the content view for the activity only once. **setContentView(XYZ);**


########======#######
try this in oncreatview,
if (view != null) {
    ViewGroup parent = (ViewGroup) view.getParent();
    if (parent != null) {
        parent.removeView(view);
    }
}
try {
    view = inflater.inflate(R.layout.fragment_main, container, false);
} catch (InflateException e) {

}

Answer 2

尝试在本地声明dialog。

java.lang.IllegalStateException：指定的子节点已经有了家长。您必须首先在孩子的父母身上调用removeView（）。

问题是你试图在Activity中连接两次相同的AlertDialog，每次尝试创建一个。

试试这段代码。

final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
                final AlertDialog alertd = builder.create();
                builder.setTitle("Select").setView(np);
                builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        currentItem.setItemQuantity(String
                                .valueOf(np.getValue()));
                        v.setSelected(true);
                        if (currentItem.getModifier_group()
                                .length() == 0) {
                            NjoyApplication
                                    .getInstance()
                                    .addNewItemWithModifiers(
                                            currentItem, "0", false);
                            updateCart();
                        } else {
                            DialogFragment dialogFrag = new selectModifier();
                            Bundle b = new Bundle();
                            b.putString("ID", currentItem.getId()
                                    + "");
                            dialogFrag.setArguments(b);
                            dialogFrag.setTargetFragment(
                                    Create_Order_ListFragment.this,
                                    Modifier.SELECT_NEW_MODIFIER);
                            b.putInt("REQUEST_CODE",
                                    Modifier.SELECT_NEW_MODIFIER);
                            dialogFrag.setCancelable(true);
                            dialogFrag.show(getFragmentManager(),
                                    "dialog");
                        }
                    }
                }).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        v.setSelected(false);
                        alertd.dismiss();
                    }
                }).show();

我希望它有所帮助！
