Cannot Inflate View While in ActivityGroup

I am using an ActivityGroup to open up Activity 2 from within Activity1, which lives under a TabHost. So I have a group of Tabs and Activity 1 is part of those, but when I click a button inside Activity 1 I want Activity 2 to open but still be under the tabs. This works fine using the following code:

    public void replaceContentView(String id, Intent newIntent) {
    View view = getLocalActivityManager().startActivity(id,newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); 
    this.setContentView(view);
}

However, within Activity 2 I have a few spinners that inflate custom windows and call for using a SimpleCursorAdapter:

    @Override
    public View newDropDownView(Context context, Cursor cursor, ViewGroup parent) {
    super.newDropDownView(context, cursor, parent);
    View view = View.inflate(context, R.layout.custom_spinner_row, null);
    int labColumn = cursor.getColumnIndex("lab");
    String getLab = cursor.getString(labColumn);
    TextView lab = (TextView)view.findViewById(R.id.CustomSpinnerTitle);
    lab.setText(getLab);        
    return view;
    }

I am getting this error:

The reason I am getting this error is because Activity 2 is not actually running because I replaced the contentView of Activity 1 with 2 in order to display it under the tabs. But I don't know any other way to do that. Is there a way to run Activity 2 under my tabs by in the same way actually run the activity rather than just replacing the contentView of 1?

Solution

  • You are using ActivityGroup that deals with View, so when you are using ActivityGroup you cannot directly setContentView(R.layout.your_xml);. In that case you have to inflate your XML into View.

    So, replace setContentView(R.layout.your_xml) by

    View contentView = LayoutInflater.from(getParent()).inflate(R.layout.your_xml, null);
setContentView(contentView);

    Hope this works for you.
