I've created a custom spinner using my own ProjectSpinnerAdapter. I've also got another class which just inflates the layout but hasn't been implemented yet so is still using the standard spinner.
I can't seem to get my custom spinner to align the same way as the standard spinner.
I'm also having problems when the length of the item is wider than the table cell as you can see below. Is there not a way to truncate the options if they are over a certain length ? - This doesn't seem like its the correct way to fix this but I can't directly set the width of the widget as this is controlled via the table layout.*
**Fixed, See update*
Screenshots
The standard spinner aligns perfectly with the Button it sits next to (they are both contained within the same TableRow)
layout
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:stretchColumns="1" >
<TableRow>
<Button
android:id="#+id/selectButton"
android:text="#string/show" />
<Spinner android:id="#+id/projectSpinner" />
</TableRow>
spinner_list_item.xml (Uses maxLength)
<?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"
>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/title_text_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:maxLength="15"
android:gravity="center"/>
</LinearLayout>
Update
The issue was the layout of the spinner item, in my custom layout spinner_list_item.xml I'd specified a layout all I needed was the textview
spinner_list_item.xml (Uses maxLength)
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/title_text_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:maxLength="15" />
If I may ask, why did you choose the TableLayout? I think the same could be achieved with a RelativeLayout and layout_toRightOf layout_below, etc. Or a LinearLayout with a weightSum and gravity each child having a layout_weight.
I'm not going to give you a solution that changes your entire layout though ;), but I tested this and this seems to work for me.
<TableRow>
<Button
android:id="#+id/selectButton"
android:maxLength="10"
android:text="sdadadasdfffffffffffffffffffffffff"/>
<Spinner
android:id="#+id/projectSpinner"
android:ellipsize="end"
android:lines="1"
android:scrollHorizontally="true" />
</TableRow>
Hopefully this works and it's a better way than setting a fixed string length
edit
I'm not sure why you're populating the spinner the way you are, but you can try:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/title_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:maxLength="15"/>
</RelativeLayout>
android:gravity is wrong too, needs to be android:layout_gravity (but that's LinearLayout only
Last edit :D
try using the default layouts
view = vi.inflate(android.R.layout.spinner_list_item, null);
then
((TextView) view.findViewById(R.id.text1)).setText(title);

Even when gravity is set to top the text has some padding between it and view's border. I need to text to completely touch the border.
Bellow you can see the gap I'm trying to get rid of.
And here is the layout used:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/someView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Here is some text"
android:textSize="30dp"
android:gravity="top" />
</LinearLayout>
Try to create 9.patch line and set it to your TextView: android:drawableTop="#drawable/your_line".
Then set android:drawablePadding="-10dp"
This trick must work perfectly.
Try this on TextView in your xml file :
android:includeFontPadding="false"
--
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/someView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Here is some text"
android:textSize="30dp"
android:includeFontPadding="false"
android:gravity="top" />
</LinearLayout>
In xml try,
android:paddingTop="-5dp"
Negative paddings always seem to work for me.
Set the height manually instead of wrapping the content.
The linear layout is the item with the padding. You need to modify that element as well to remove the space.
As easy as it seems to be, as stubbornly this ListView won't center itself (or it's content within - doesn't matter to me).
This is activity layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.drobiazko.den.mobineon.MainActivity"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center_horizontal"
android:background="#drawable/bg">
<RelativeLayout android:id="#+id/clock_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<!--<RelativeLayout android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/holo_blue_dark">-->
<com.drobiazko.den.mobineon.ListViewRowsHeight
android:id="#+id/listview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:overScrollMode="never"
android:scrollbars="none"
android:divider="#null"
android:listSelector="#android:color/transparent"
android:persistentDrawingCache="scrolling|animation"
android:background="#android:color/holo_green_dark" />
<!--</RelativeLayout>-->
</LinearLayout>
This is ListView's item layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView android:id="#+id/btn_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/custom_btn_icon" />
<TextView android:id="#+id/btn_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/custom_btn_name" />
<TextView android:id="#+id/btn_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/custom_btn_count" />
</RelativeLayout>
I've tried everything (including simplifying layout to max), but it still won't go.
Funny that the first relative layout clock_container - centers like a charm, due to parent LinearLayout's android:gravity="center_horizontal". Why won't ListView?
Added later:
Inspired by FOliveira's answer, I've done some investigation and found that:
everything works fine, parent LinearLayout has android:gravity="center_horizontal" and centers his children respectfully. The reason for ListView's children are left-aligned is that ListView takes all possible width despite his android:layout_width="wrap_content" attribute.
Anyone knows why is that?
First of all , i would remove the first linear layout and stay only with the relative layout as the parent.
After having the relative layout as the main parent , set the CENTER_IN_PARENT attribute to true.
The mistake you are making is that you are setting the gravity of Linear Layout child to center horizontal, which is correct, but the only children being affected by this option is the Relative layout itself.
I'm trying to create an expandable list where I can make the height of the group_row smaller, to use less screen space. When I change the layout_height of the LinearLayout, it changes the height to what I want it, but all of the labels of each TextView aren't displayed; they disappear. However, when it is wrap_content, the text appears. Any ideas how to fix?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="35dp">
<TextView android:id="#+id/childname
android:paddingLeft="0dp"
android:textSize="16dp"
android:textStyle="italic"
android:layout_width="150dp"
android:layout_height="wrap_content">
</TextView>
</LinearLayout>
Textview id should be android:id="#+id/childname"
I have made myself a custom LinearLayout by the name of com.theflyingnerd.DroidMe.DiscreteNumericalRangeSelectorWidget that hosts a couple of spinner widgets. This custom LinearLayout inflates the following XML layout (You might not need to look at this too carefully but it's here for completeness):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<!-- Min value Spinner -->
<Spinner
android:id="#+id/discrete_numerical_range_selector_min_value_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left"
android:layout_weight="1" />
<TextView
android:id="#+id/to_text"
android:text="to"
android:textSize="14sp"
android:paddingLeft="10sp"
android:paddingRight="10sp"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:layout_weight="0">
</TextView>
<!-- Max value Spinner -->
<Spinner
android:id="#+id/discrete_numerical_range_selector_max_value_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right"
android:layout_weight="1" />
I have placed one such object in the layout for one of my activities like so:
<?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="fill_parent"
android:orientation="vertical">
<include layout="#layout/search_form_section_generic_top"/>
<include layout="#layout/search_form_section_car_specific"/>
<com.theflyingnerd.DroidMe.DiscreteNumericalRangeSelectorWidget/>
<include layout="#layout/search_form_section_advanced_options" />
</LinearLayout>
The problem is that my app force closes immediately upon startup. I've checked by putting breakpoints in my custom LinearLayout that none of my custom code is even being run yet. Furthermore, if I copy-paste the layout code for my compound widget in place everything works, which indicates to me that I probably haven't left any important XML attributes out. What could be going wrong?
I fixed it by making the LinearLayout XML element in the widget layout into a merge instead, and moved all of the layout parameters out of the widget XML file and into the activity XML itself, thus replacing
<com.theflyingnerd.DroidMe.DiscreteNumericalRangeSelectorWidget/>
with
<com.theflyingnerd.DroidMe.DiscreteNumericalRangeSelectorWidget
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
If someone could tell me why this worked, it might help me and others doing it again, and you can take credit.
because you must specify the width and height of every view you use in you xml?

==================== code for list content field
it have linerlayout with three field to set on list...
===== here code for my activity
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); setContentView(R.layout.main); getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.header);
. ;.---- help me get the clear view of gallery in header without hidding at bottom or simply how can i increase height of header layout.
As WarrenFaith said, we can't help you without the XML code. The basic answer with the informations you gave is layout_height but you can have set fill_parent and layout_weight to other fields and it would not be the same. Please provide some code
#MGSenthil: everybody was once new here. Simply work with and not against us :)
Back to topic: What do you mean with because the height of header can't being changed in any sense? Please clarify if you cant change the height because it didnt work or if you cant change it because it has to be this size?!
If you want to have this header with a specific size, you should consider to remove something of the content so it fits.
I never used a custom title, but you should check if its not better to request NO_TITLE and simply add your header to the main.xml layout? You should be able to increase the height of your header that way.
