I have some code that displays a ListView and allows an item to be clicked to take it to a single view activity. However, for some reason the onClickListener isn't working. I thought that this may be due to the EditText being focusable. However, upon setting this to false, I found it was not the case.
listview_item.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5sp"
android:textSize="15dp"
android:inputType="textMultiLine">
</TextView>
Use android:descendantFocusability="blocksDescendants" in your list item layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:descendantFocusability="blocksDescendants">
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5sp"
android:textSize="15dp"
android:inputType="textMultiLine" />
</LinearLayout>
Replaced fill_parent by match_parent as it's deprecated.
Remove the inputType attribute on you TextView layout:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:textSize="15sp"/>
Also as you can see I'm using the match_parent and wrap_content for width and height respectively. fill_parent is deprecated now.
Match parent means it will fit the whole ListView in width and wrap content is that the hieght will span as much as needed, therefore the whole text will be visible, even if it's multi-line.
Another note: for text sizes you use sp for widths, heights, etc you use dp. Worthy article explains it further.
Background tasks once executed will not have a handle. So your listview listener will be killed. You need to remove it from the background and have it in your onCreate. You can set a flag in postExecute and do implementation if it is dependent on that.

I have a list of items in a horizontal recycler view, and a fairly simple item that should only have a TextView set to wrap_content and an ImageView that should be aligned to the right of the layout.
Theoretically I should be able to just set a layout_weight of 1 on the TextView, but that causes a random space to randomly show up sometimes in the view depending on where it is in the recycler view.
Is there anyway to align the close icon to the right, while still keeping the layout/textview width as wrap_content? The amount of text can vary quite a bit, so I can't actually set a fixed width. I'm fairly certain that I can't just set a layout_gravity of end on the ImageView since the parent layout's set to wrap_content.
See layout attached.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/rounded_corners"
android:minWidth="#dimen/min_width"
android:maxWidth="#dimen/max_width"
android:orientation="horizontal">
<WPTextView
android:layout_width="0dp"
android:layout_height="match_parent"

<ImageView

android:layout_height="match_parent"
android:layout_gravity="center_vertical|end"/>
</LinearLayout>
With out knowing what the items are supposed to look like and how it needs to behave it is hard to judge what the problem you are having is.
If the image is just supposed to be a small image to the right of the text you could just add a right drawable to the text view:
https://developer.android.com/reference/android/widget/TextView.html#attr_android:drawableRight
If you can replace the LinearLayout by RelativeLayout then you are good to with
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/rounded_corners"
android:minWidth="#dimen/min_width"
android:maxWidth="#dimen/max_width">
<WPTextView
android:id="#+id/tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/tv" />
</RelativeLayout>
Spacing between TextView and ImageView can be adjusted with margin on them. The properties used in the above code are self-explanatory.
I have two views, a day view and a event view as part of a calendar. I want my events to fill the day view in width (which is working) but when I add another at the same position/time I want them to split the width... I am adding my event dynamically using java. Is there an attribute I can use so that views don't overlap?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:id="#+id/dayView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/day_view">
</RelativeLayout>
.
<?xml version="1.0" encoding="utf-8"?>

I think you need to use Linier layout as parent view with horizontal orientation. And also use concept of weight for width. It will devide your parent view according to child quantity
Take a look on RelativeLayout.LayoutParams
You could set rules at runtime, using ID's.
layoutparams.addRule(RelativeLayout.ALIGN_RIGHT, R.id.id1)
Although, i think, that using LinearLayout would be much simpler.
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);
I have a problem with my list item layouts that i cannot understand. I set the height of a list item to 70dp but if i only have content with a total height of 40dp it will automatcally just ignore the value i set with android:layout_height and instead use what seems to be wrap_content as the height.
If i use the exakt same layout outside of a list it works as intended.
below is the layout of a list item from one of my lists.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="70dip"
android:layout_width="fill_parent">
<TextView android:id="#+id/name"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
style="#style/NormalText"/>
<TextView android:id="#+id/description"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
style="#style/VerySmallLightText"/></LinearLayout>
Editted my xml to reflect my code better. i have some of there attributes in style, that is why i accidently made a typo when tying it in manually here.
Have you tried layout_height of the linear layout instead of just the height?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="70dp"*
android:layout_width="fill_parent">
your linearlayout attribute the following
android:height = '70dip' is it can passing the IDE checking?
Here is my layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:id="#+id/LinearLayout01"
android:layout_height="wrap_content">
<Spinner android:text="#+id/AutoCompleteTextView01"
android:id="#+id/Spinner01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:width="130dp"></Spinner>
<EditText android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/Chapter" android:width="30dp"></EditText>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/TextView01" android:text=":"></TextView>
<EditText android:layout_height="wrap_content"
android:layout_width="wrap_content" android:id="#+id/Verse"
android:width="40dp"></EditText>
</LinearLayout>
I inflate this layout as an AlertDialog's view. But when I pick a large element, the text fields get pushed out to the right. Is there any way to set the maximum size of the spinner so after choosing an element, it shortens the choice with an ellipsis ("...") or something?
No need to use a custom adapter. Use the android.R.layout.simple_spinner_item and then change it from ellipse marquee to end ellipse. Then set your new change layout file as layout id or use this layout file
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
style="?android:attr/spinnerItemStyle"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingRight="10dp"
android:ellipsize="end" />
The size of a Spinner set have android:layout_width="wrap_content" is determined by its content. If you want things ellipsized, that's up to you in your SpinnerAdapter, when you create your row Views.
Or, hard-wire an android:layout_width that is fixed in size.
Or, instead of using LinearLayout, use RelativeLayout and structure your rules such that the Spinner takes up the remaining space on the row, by anchoring it to the left side of the screen and to the left side of the first EditText. Though I'm not 100% certain what then happens if the content is too big -- it probably just gets truncated.
Set spinner android:background="#null" to solve the problem.
This will also hide the dropdown icon visibility
