Question

I will show a popup screen for getting some description from the user. I can add almost every control (textview, button, checkbox, etc) without any problem except EditText. It gives me an error as below.

Caused by: android.view.InflateException: Binary XML file line #12: Error inflating class <unknown> 

CODE SIDE

    public RouteAdapter(Activity a, RouteResultDto list, boolean editMode, BaseFollower userInfo, boolean isFavoriteStatus) {
    this.activity = a;
    this.routeList=list;
    this.editMode = editMode;
    this.userInfo = userInfo;
    this.isFavorite = isFavoriteStatus;
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    imageLoader=new ImageLoader(activity.getApplicationContext());

//throws the exception at line below
    lnPopupMain = (LinearLayout) LayoutInflater.from(activity).inflate(R.layout.popup_route_edit, null);

    float width = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 200, activity.getResources().getDisplayMetrics());
    float height = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 250, activity.getResources().getDisplayMetrics());
    popupEditRoute = new PopupWindow(lnPopupMain, (int)width, (int)height, true);

    popupEditRoute.setBackgroundDrawable(new BitmapDrawable());
    popupEditRoute.setOutsideTouchable(true);
}

LAYOUT SIDE

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:padding="10dip"
              android:layout_width="200dip"
              android:layout_height="160dip"
              android:background="@color/black"
              android:id="@+id/lnPopupMain"
              android:focusable="true"
        >

    <EditText android:layout_width="match_parent"
              android:layout_height="80dip"
              android:id="@+id/txtRouteEdit"
            android:background="@color/white">
    </EditText>
</LinearLayout>

(There is no any exception if I use TextView or Button instead of EditText. What is the problem with EditText?)

Resolved. I dont know why but you should create popup window in listener.

        imgEditOk.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                lnPopupMain = (LinearLayout)inflater.inflate(R.layout.popup_route_edit, null);
                float width = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 200, activity.getResources().getDisplayMetrics());
                float height = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 250, activity.getResources().getDisplayMetrics());
                popupEditRoute = new PopupWindow(lnPopupMain, (int)width, (int)height, true);
                popupEditRoute.setBackgroundDrawable(new BitmapDrawable());
                popupEditRoute.setOutsideTouchable(true);
                popupEditRoute.showAtLocation(lnPopupMain, Gravity.CENTER, 10, 10);
            }
        });
