Up caret shows navigation drawer

Up caret shows navigation drawer - android

Nothing much more to say. I'm using a single activity and I go into a Fragment which calls setDisplayHomeAsUpEnabled(Boolean.TRUE) and setHasOptionsMenu(Boolean.TRUE). The menu has two items and the interactions with them are right. I have set breakpoints on all onOptionsItemSelected of the app (which includes the Activity, the Fragment, and the drawer toggle) but when I debug, the menu opens and no breakpoint is triggered.
The Activity and Fragment code in case they help:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/navigation_drawer"
android:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:animateLayoutChanges="true">

layout="#layout/toolbar_default"

I have opted for making an activity only for that fragment which doesn't include the nav drawer. But obviously this doesn't answer the question, it just gets a relatively similar behavior.

NavigationDrawer in certain fragment

Here is the problem, I want my navigation drawer (the hamburger icon), only appears in certain fragment. In my case, I have three fragment, using tab layout and view pager to change between fragment. I have implement an interface which I have created. But when I set to true, the hamburger icon appear in all fragment. I don't know where my problem is in my code.

Just ask for more detailed, thanks

Just add tab Layout change listener and hide and show icon according to the requirement.

Navigation is in hidden mode, change it to visible.. it will work

whenever i run the app on emulator it says unfortunately the app has stopped working and the log reads the below lines

here is your error...
android.support.v4.widget.SwipeRefreshLayout cannot be cast to com.example.intel.dualboot.InSwipeRefreshLayout

You have initialize SwipeToRefresh in XML as "android.support.v4.widget.SwipeRefreshLayout" But you are trying to create object of that view as "com.example.intel.dualboot.InSwipeRefreshLayout". So you got an error because of wrong casting of class. Change "android.support.v4.widget.SwipeRefreshLayout" to "com.example.intel.dualboot.InSwipeRefreshLayout" in xml to solve your problem.

replace
com.exmaple.intel.dualboot.InSwipeRefreshLayout
with
android.support.v4.widget.SwipeRefreshLayout
in your xml file,
as the com.exmaple.intel.dualboot.InSwipeRefreshLayout class is not defined

com.exmaple.intel.dualboot.InSwipeRefreshLayout
Check this path if it is correct in your xml.It seems the path of "InSwipeRefreshLayout" is not corect

in your xml

the com.exmaple.intel.dualboot.InSwipeRefreshLayout has that spelling of "exmaple", it should be example.

The posted layout working fine for me.Please check the package name properly com.example.intel.dualboot.InSwipeRefreshLayout whether exist or not and clean and build the project.

Changing Gridview Size from Preferences when Implementing Fragments

I had a gridview activity where I was populating the gridview with a custom object (a picture with some custom methods and an onclick listener). I could change the gridview size from the preferences menu. Everything worked beautifully.
I have since added some complexity to the code. Instead of using the normal Activity class, I am now using the FragmentActivity class, a fragmentPageAdapter, and a fragment to which my gridview is bound. This is because eventually I want the app to allow the user "swipe" from fragment to fragment.
Since using the fragment in this way, I am noticing a repeatable bug whenever I try to resize the gridview from the preferences menu: some of the objects get resized properly, other elements do not resize. Instead, they keep the same size that they had prior to changing the preference. Here is a screenshot:
This only happens when I try resizing from the preferences menu. Other calls to my resize method, such as on a configuration change, resize all of the gridview elements correctly.
I would appreciate any suggestions!
Here is my Code:

MY CUSTOM OBJECT CLASS. THESE OBJECTS ARE POPULATING THE GRIDVIEW:

MY PREFERENCE ACTIVITY:

#SuppressWarnings("deprecation")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
Log.i("Khalid", "Preferences: onCreate");
}
}
MY XML FOR MY MAIN ACTIVITY:
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v4.view.PagerTitleStrip
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/lbl_title"
android:background="#33B5E5"
android:layout_gravity="top"
android:paddingTop="0dp"
android:paddingBottom="0dp"> "
</android.support.v4.view.PagerTitleStrip>
</android.support.v4.view.ViewPager>
AND FINALLY, MY XML FOR THE GRIDVIEW:
<?xml version="1.0" encoding="utf-8"?>
<GridView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/lbl_gridView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:layout_margin="0px"
android:alwaysDrawnWithCache="false"
android:animateLayoutChanges="false"
android:background="#android:color/white"
android:columnWidth="130dp"
android:drawSelectorOnTop="true"
android:horizontalSpacing="#dimen/activity_horizontal_margin"
android:listSelector="#null"
android:numColumns="auto_fit"
android:padding="#dimen/activity_horizontal_margin"
android:scrollbarStyle="insideOverlay"
android:smoothScrollbar="true"
android:stretchMode="none"
android:verticalSpacing="#dimen/activity_vertical_margin" >
</GridView>

Use CENTER_INSIDE a scale type for your image view.
super.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
another thing that I would change is the way you handle the column width. I would remove the android:numColumns="auto_fit". On the other hand you know that the number of columns is the cealing of WidthViewGrid/desiderePicSize, where the most common case for WidthViewGrid is the screen's width. On then programmatically you can set number of columns of your GridView with setNumberOfColumns

I would say:
A. After calling setColumnWidth call the gridview.invalidate()
B. After returning from the change preference - call adapter's notifyDataSetChanged in order to make sure it re-creates the views in the adapter (i.e. getView will be called)

How to dynamically add user input into a listView within a fragment?

Im trying to add text into a listview within a fragment but i keep getting an error: cannot find symbol method setListAdapter(ArrayAdapter).
I'm using this tutorial as reference but it only shows how to do it within a activity : http://wptrafficanalyzer.in/blog/dynamically-add-items-to-listview-in-android/

Up caret shows navigation drawer - android

I have opted for making an activity only for that fragment which doesn't include the nav drawer. But obviously this doesn't answer the question, it just gets a relatively similar behavior.
