how to set android ImageView visibility inside an included layout?

We are using android API 17 in our application. I have defined a layout containing two images vies as below:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/image_container_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/image_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/image_1_resource"/>
<ImageView
android:id="#+id/image_2"
android:layout_marginTop="3dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/image_container_layout"
android:src="#drawable/image_2_resource"/>
This layout is included inside another layout as below:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
style="#style/wizard_content_style"
tools:context=".ui.Wizard"
android:orientation="vertical"
android:gravity="center_vertical"
android:layout_gravity="center_vertical"
>
<include layout="#layout/image_container_layout"
android:id="#+id/included_view"
/>
<TextView
style="#style/wizard_content_text_style_medium"
android:id="#+id/text_description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/included_view"
android:layout_centerHorizontal="true"
android:gravity="center_horizontal"
android:layout_gravity="center_horizontal"
android:text="#string/instruction"
android:layout_marginBottom="15dp"/>
The reason that the layout is included is that we want to reuse it in two more layouts.
Now based on some condition I want to hide or show the image views inside image_container_layout.
The java code looks like this:
containerLayout = (ViewGroup) ((Activity) getAndroidContext()).getLayoutInflater().inflate(R.layout.image_container_layout, null);
image1 = (ImageView) containerLayout.findViewById(R.id.image_1);
image2 = (ImageView) containerLayout.findViewById(R.id.image_2);
switch (accuracy) {
case 1:
log().i(getClass().getSimpleName(), "case 1 chosen");
image1.setVisibility(View.VISIBLE);
image2.setVisibility(View.GONE);
log().i(getClass().getSimpleName(), "image 1 has been shown");
break;
case 2:
image1.setVisibility(View.GONE);
image2.setVisibility(View.VISIBLE);
break;
case 3:
image1.setVisibility(View.VISIBLE);
image2.setVisibility(View.VISIBLE);
break;
}
I am debugging this code and I am sure the code is running. The log messages are printed in Logcat as well, but nothing happens no change in the images. Also, both images are always shown.
I wonder if there is something that I have to do when working with the included layout?
Thanks for any help in advance.
Based on answers I got below, seems that inflating a view will create a new object and because of this, changes in the visibility are not shown on the user interface.
Then the question is that if we have a wizard and inside 3 different pages of the wizard I want to have an image and depending on some condition I want to show or hide the image, what is the best solution? I mean I want to reuse the code which is responsible for hiding and showing the image regardless which page of wizard is active.

Why are you complexing with so much code. If you include some layout in your xml then you can use those widgets also same as the xml have. There is no need to inflate.
ImageView image_2 = findViewById(R.id.image_2);
image_2.setVisbility(Visible.GONE);

You said at this comment the code not inside activity but wherever it is you inflated a new layout to your view currently displaying by this line:
containerLayout = (ViewGroup) ((Activity) getAndroidContext()).getLayoutInflater().inflate(R.layout.image_container_layout, null);
When you try to change visibility of those images actually it works, i think so. But if your activity or fragment layout contains image_container_layout maybe you see
those images.
And I wonder that what do you do with inflated view containerLayout. Do you add it to inside of any other view. If you dont it wont be visible for you.

you have to use it like this:
View included_view1 = findViewById(R.id.included_view1);
ImageView image_1 = included_view1.findViewById(R.id.image_1);
ImageView image_2 = included_view1.findViewById(R.id.image_2);
image_1.setVisibility(View.VISIBLE);
image_1.setVisibility(View.GONE);
image_2.setVisibility(View.VISIBLE)
image_2.setVisibility(View.GONE)
View included_view2 = findViewById(R.id.included_view2);
ImageView image_11 = included_view2.findViewById(R.id.image_1);
ImageView image_22 = included_view2.findViewById(R.id.image_2);
image_11.setVisibility(View.VISIBLE);
image_11.setVisibility(View.GONE);
image_22.setVisibility(View.VISIBLE)
image_22.setVisibility(View.GONE)
Above code will be helpful in the case of multiple time you want to use same layout.

How can I change the color of selected item from ListView?

I have created an android project in which i have a list view with 6 items.
I want that every time I select any item from the list, it gets a colour orange which stays until I press button submit.
the code is:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.SafeWalkApp.SecondActivity" >
<ListView
android:id="#+id/sampleListView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"
android:background="#android:color/transparent"
android:cacheColorHint="#android:color/transparent"
android:divider="#CCCCCC"
android:dividerHeight="1dp"
android:entries="#array/vol_list" >
</ListView>
<Button
android:id="#+id/onsubmit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="#string/submit" />
</RelativeLayout>
this is my xml code.
I have tried adding the color to color.xml but that is showing me an error message and basically it is for the backgroung. So please help me out on this.

Well if you are using a custom listview and had an item set by custom adapter then you can change the color of the listview item in
nList = (ListView) findViewById(android.R.id.yourlistname);
nList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
}
});
In above function nList is the list in which you want to make change and in its on click listner you can get the selected item view as in its parameters as View arg1 and from that you can get the linear layout and its all other controls and make changes to any control color, text etc as you want
get the view in here and set any color you want by getting the view and setting its background etc.
I can not write the whole code here but I hope you get my?

You must create state drawable colors. And some xml.files to define different colors depending on the state of your row.
Maybe this can help you.
How to change color of ListView items on focus and on click
Android LinearLayout with color resource: What am I doing wrong?

Make a class that contains all the info that is needed for your adapter item + a boolean variable, that you are going to check in adapters getView, if the variable is going to be true, change the color to orange else normal color.
in onItemClick find the position of the correct object in the list that you gave to your adapter and change its boolean value.
after that refresh the adapters referenced list.
Call notifyDataSetChanged() on your adapter. Now according to point(1.) the adapter is going to check the boolean value of the item and change its color to orange.

how to create android linearlayout with RTL horizontal orientation

I want to create a linear layout with horizontal orientation
but I want it to position its children aligned to its right and not to its left as usual
how can I do this?
I know how to do this using relativeLayout, but I want to practice linearLayout

You can use android:layoutDirection attribute which is introduced in 4.2(jelly bean).
The following links will help.
http://developer.android.com/reference/android/view/View.html#attr_android:layoutDirection
http://android-developers.blogspot.co.uk/2013/03/native-rtl-support-in-android-42.html

if you are using Android studio you can do this:
1- right click on the project main folder
2- refactor
3- add support for RTL

you can use this code snippet to reverse your layout views.
LinearLayout ll = // inflate
ArrayList<View> views = new ArrayList<View>();
for(int x = 0; x < ll.getChildCount(); x++) {
views.add(ll.getChildAt(x));
}
ll.removeAllViews();
for(int x = views.size() - 1; x >= 0; x--) {
ll.addView(views.get(x));
}
OR
To begin supporting RTL layouts in your app, set the android:supportsRtl attribute to the element in your manifest file and set it “true". Once you enable this, the system will enable various RTL APIs to display your app with RTL layouts. For instance, the action bar will show the icon and title on the right side and action buttons on the left, and any layouts you’ve created with the framework-provided View classes will also be reversed.
Look at this android doc

You can set on the parent view element's gravity to right
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" <!-- make sure this is not wrap_content !-->
android:layout_height="match_parent"
android:orientation="horizontal"
android:gravity="right" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="A"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="B"/>
</LinearLayout

TextView setGravity() doesn't work in java

I'm stuck on a problem and I don't know, what causes it.
I have a very simple Layout like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/my_text_view"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="NOTE_THIS"
android:textColor="#FFFFFF"
android:textSize="22dp"
android:text="TestText"/>
</LinearLayout>
which is included inside another layout. If I change the gravity inside the xml I see same Result in Layout-Editor and on my phone. If I wanna apply the Gravity programatically like with myTextView.setGravity(Gravity.CENTER) it doesn't Change anything. And I cannot set LayoutGravity in Java on a TextView
I'll tried for debug purposes to include them three times each with another gravity which does work even. So I assume everything is alright with my Layout and there has to be a Bug or something else I miss.
Can someone give me a hint what I also can try, or what causes this problem?

Set your TextView's width as android:layout_width="fill_parent" then you can set it programmatically using myTextView.setGravity(Gravity.CENTER)

You need to set the gravity of the LayoutParams object instead of the View itself:
TextView tv = new TextView(getApplicationContext());
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT);
lp.gravity = Gravity.CENTER;
tv.setLayoutParams(lp);

When you use LinearLayout as parent, then layout_gravity comes in picture which align control but not content inside the control so,
Instead using android:layout_gravity use android:gravity.

How to programmatically hide android some, but not all, view items in an XML output?

I'm trying to program a disc golf scoring app on Eclipse for my android phone. I'd like to set it up for up to 6 players, but mostly 2 people will use it for a game. The data is being stored in a sqlite DB, and I am using a SimpleCursorAdapter to populate the data for holes that have already been scored. here is that code:
private void fillData() {
Cursor notesCursor = mDbHelper.fetchAllNotes();
startManagingCursor(notesCursor);
// Create an array to specify the fields we want to display in the list (only TITLE)
String[] from = new String[]{DiscGolfDbAdapter.KEY_HOLE,
DiscGolfDbAdapter.KEY_PAR,
DiscGolfDbAdapter.KEY_TOM_HOLE,
DiscGolfDbAdapter.KEY_TOM_GAME,
DiscGolfDbAdapter.KEY_CRAIG_HOLE,
DiscGolfDbAdapter.KEY_CRAIG_GAME,
DiscGolfDbAdapter.KEY_TOMS_POSITION,
DiscGolfDbAdapter.KEY_SKIP_PLAYER
};
// and an array of the fields we want to bind those fields to (in this case just text1)
int[] to = new int[]{R.id.schole, R.id.scpar, R.id.scth, R.id.sctg, R.id.scch, R.id.sccg, R.id.sctp,
R.id.skip};
// Now create a simple cursor adapter and set it to display
SimpleCursorAdapter notes =
new SimpleCursorAdapter(this, R.layout.hole_info, notesCursor, from, to);
setListAdapter(notes);
}
From searching the internet I've found what I think are two posibilities that SHOULD work, but do not.
First I've tried the XML Attribute: android.visibility. It looks like this in the PORTION of the view that I am trying to "test" hide:
<LinearLayout android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android.visibility="GONE">
<TextView android:id="#+id/scch"
android:layout_width="45dip"
android:gravity="right"
android:textSize="25sp"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/sccg"
android:layout_width="45dip"
android:gravity="right"
android:textSize="25sp"
android:layout_height="wrap_content"/>
</LinearLayout>
I have tried it with "GONE", "Gone" and "gone". NONE of them work in the eclipse emulator OR on my actual phone. So, there is no point in trying to parameterize this attribute.
Next I've tried setting the XML attribute for android:layout_height to "0dip". This indeed works in the emulator and on my phone WHEN IT IS HARDCODED.
Then I moved to the next logical step (as I see it), storing a parameter in the DB so that I can "show" or "not show" the item DEPENDING on conditions within the record. So, I've stored a field in the DB with two values "0dip" and "wrap_content". I pass these to the layout as shown in the java above as R.id.skip. I've also added these to the output just to audit that they are really there. Here is that XML:
<LinearLayout android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="#+id/skip">
<TextView android:id="#+id/scch"
android:layout_width="45dip"
android:gravity="right"
android:textSize="25sp"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/sccg"
android:layout_width="45dip"
android:gravity="right"
android:textSize="25sp"
android:layout_height="wrap_content"/>
</LinearLayout>
<TextView android:id="#+id/skip"
android:gravity="center"
android:layout_width="315dip"
android:textSize="10sp"
android:layout_height="wrap_content"/>
In the above test, both via the Eclipse emulator and my android phone, the last TextView confirms that the DB contains either "0dip" or "wrap_content", BUT the LinearLayout with:
android:layout_height="#+id/skip">
behaves as if it were "0dip" ALL of the TIME. In other words, I cannot PROGRAMMATICALLY" affect the XML attribute for android:layout_height.
If there is a better/more standard way of accomplishing what I am trying to do, please share - BUT BE CLEAR. I am new, so CODE EXAMPLES wwill work best for me.
May 29th - It seems to me (based on testing) that you cannot alter layout attributes for the layout specified in this code:
SimpleCursorAdapter notes = new SimpleCursorAdapter(this,
R.layout.hole_info,
notesCursor, from, to);
setListAdapter(notes);
Anything I try leads to some error ort another. So, I've seen examples of custom list adapters where these attributes are altered, so I'm trying to convert to a custom list adapter.

Why not do it in code?
LinearLayout ll = (LinearLayout)findViewById(R.id.your_layout_id);
ll.setVisibility(View.GONE);

Your XML layout code
android.visibility="GONE"
should be
android:visibility="GONE"
Change visible of a LinearLayout like Gabriel Neguţ say:
LinearLayout ll =
(LinearLayout)findViewById(R.id.your_layout_id);
ll.setVisibility(View.GONE);
or change height of LinearLayout:
LinearLayout ll = (LinearLayout)findViewById(R.id.your_layout_id);
LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) ll.getLayoutParams();
lp.height = 0; // or lp.height = LinearLayout.LayoutParams.WRAP_CONTENT;
ll.setLayoutParams(lp);

What about this guy's solution http://enjoyandroid.wordpress.com/2012/03/12/customizing-simple-cursor-adapter/
Kind of worked for me.
