Within my main.xml, I have a table that has 2 columns and 2 rows; one for latitude & longitude and their associated values. I want them to be centered within their columns, and from my readings it seemed the best way to do that is with layout_weight="1" and gravity="center". This did work most of the time, but since I have made changes elsewhere in the code, now none of the items in gps_layout are centered unless the configuration is changed, in this case when I change the orientation by rotating the phone.
I know that rotation causes the app to go through its lifecycle (also is there a shorthand for talking about that other than calling it rebirth?) but I cannot understand what is different about the app after the first run, except for its saved state ... which would not seem to have much effect on centering. Thanks! Sorry if I did not format this question correctly, I have been trolling SO for awhile but this is my first question.
<TableLayout
android:id="#+id/gps_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="invisible"
>
<TableRow>
<TextView
android:layout_column="1"
android:id="#+id/lat_text"
android:text="latitude: "
android:layout_weight="1"
android:gravity="center"
/>
<TextView
android:id="#+id/lon_text"
android:text="longitude: "
android:layout_weight="1"
android:gravity="center"
/>
</TableRow>
<TableRow>
...etc...
</TableRow>
</TableLayout>
Since I couldn't reproduce your error, I'd suggest you give a try to a different layout (with the same supposed resulting display aspect), like:
<LinearLayout android:id="#+id/gps_layout" android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_alignParentTop="true" android:layout_alignBottom="#id/acquire"
android:visibility="invisible">
<LinearLayout android:orientation="vertical" android:layout_weight="1"
android:layout_height="wrap_content">
<TextView android:id="#+id/lat_text"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:text="latitude: "
android:gravity="center" />
<TextView android:id="#+id/lat_data"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:text="(lat goes here)"
android:gravity="center" />
</LinearLayout>
<LinearLayout android:orientation="vertical" android:layout_weight="1"
android:layout_height="wrap_content">
<TextView android:id="#+id/lon_text"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:text="longitude: " android:gravity="center" />
<TextView android:id="#+id/lon_data"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:text="(lon goes here)"
android:gravity="center" />
</LinearLayout>
</LinearLayout>
Hopefully it will solve the problem on your cy 7.0.1.
Update
Some advises regarding your code:
In the MyLocationListener you shouldn't set every time the visibility of the two layout, this way it would be more effective:
#Override
public void onLocationChanged(Location loc)
{
if (acquire_view.getVisibility() == View.VISIBLE)
{
acquire_view.setVisibility(View.INVISIBLE);
gps_view.setVisibility(View.VISIBLE);
}
}
also, in onProviderEnabled method, and everywhere where you set the visibility of one layout (acquire_view/gps_view), you should also set for the other as well.

I've got a layout that utilizes a table with a couple of rows. I'm attempting to use the API 26 autoTextSize functionality to ensure the text stays on a single line. The issue that I'm having is with the text being cut in half on first display in my list. If I scroll down the list, the text is fine, and then when I come back up to the top of the list my text is fine, but when it first displays it is cut in half. Here's the code I'm using for auto sizing.
<TableLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:gravity="center">
<TableRow
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minHeight="30dp"
android:gravity="center">
<TextView
android:id="#+id/AITAsymbol"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:autoSizeMaxTextSize="30dp"
android:autoSizeMinTextSize="24dp"
android:autoSizeStepGranularity="2dp"
android:autoSizeTextType="uniform"
android:textAlignment="center"
android:textColor="#000000" />
</TableRow>
<TableRow
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center">
<TextView
android:id="#+id/received"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAlignment="center"
android:textColor="#ffffff" />
</TableRow>
</TableLayout>
Am I missing something with regards to how I should be using the auto sizing feature in Android?
You need to keep either layout_width or layout_height fixed for the Auto Text Sizing property to work.
I've got a need to display and TextView (label), EditText(Input) and TextView(suffix) in a line.
The issue I have is - if the label TextView is too long it The EditText and Suffix TextView and not drawn.
Here's my code.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_weight="0"
android:padding="5dp"
android:text="Label"
android:id="#+id/label_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<EditText
android:layout_weight="1"
android:id="#+id/input_edit_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColorHint="#color/dark_grey"
android:textColor="#color/black"
android:hint="text.." />
<TextView
android:padding="5dp"
android:layout_weight="0"
android:text="Suffix.."
android:background="#color/lite_grey"
android:id="#+id/suffix_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
So what I want is - even if the label is over 2-3 lines, for an EditText to appear followed by another TextView.
Any pointers would be appreciated.
Thanks!
Edit:
I've added some 'diagrams' so you can understand what I want to do a bit better.
The label to the EditText can be arbitrary length(2/3 lines), so whenever the label finishes I want an EditText to start (which is followed by another TextView showing a suffix..)
..
![This shows a 2 line label and TextView..]
Edit 2: Thanks for the responses guys!! I think #questioner has really understood what I want to do i.e. I want your 3 views to move to other lines so that they behave like they were one view - and as he has suggested i'll have to find a library for this!
How about this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:padding="5dp"
android:text="Label"
android:id="#+id/label_text_view"
android:layout_width="100dp"
android:layout_gravity="center_vertical"
android:layout_height="wrap_content"/>
<EditText
android:layout_weight="1"
android:id="#+id/input_edit_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textColorHint="#color/dark_grey"
android:textColor="#color/black"
android:hint="text.."/>
<TextView
android:padding="5dp"
android:text="Suffix.."
android:layout_gravity="center_vertical"
android:background="#color/lite_grey"
android:id="#+id/suffix_text_view"
android:layout_width="100dp"
android:layout_height="wrap_content"/>
</LinearLayout>
If you want your 3 views to move to other lines so that they behave like they were one view - you should use external library for that.
Why not use a RelativeLayout instead of LinearLayout and then use android:layout_below="#+id/..." or android:layout_above="#+id/..." also android:layout_toRightOf="#+id/..." or android:layout_toLeftOf="#+id/..."
Set
android:layout_weight="1"
for each view so that they all occupy the same amount of horizontal space.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="1">
Try this or please expand a little more.
Hooray for pictures! Here's what it looks like when assigning the picture to the background, and when not.
I'd very much like for it to not stretch out the top TableView if the image is larger than the table. I've included an empty "view" to give a little bit of extra space for the table's background already as well, as you can see in the XML to follow. Tried to mess around with ScaleType, but that was a wash.
How can I get the BG to stretch to fit the layout? I'm trying to handle the "user xxx has a smaller screen than WVGA" gracefully. I lack grace, apparently.
<TableLayout

The tablelayout is the first element of the root linearLayout, if that matters at all.
Edit: Alternatively, if you know how I could measure the tableLayout's X and Y space before assigning the image, I could scale it programmatically before assigning it.... Either solution would be good if anyone knows!
I would use FrameLayout and create two layers (i.e. add two views inside). First would be an ImageView and the second, therefore the top one, would be your table. In this way I would not rely on the table to control my image scaling but it would be independent from the ImageView which one can then hopefully more easily manipulate as it is not showing the image as 'background' but as the source.
I have a TextView which I fill with text from a string resources in strings.xml. The string resource contains < li > elements to create a bullet list inside the TextView. My problem is that I want to control the indention of lines in the bullet list that span over more than one line. Default the text isn't indented past the bullet so it looks kind of ugly. Is it possible to do this with style parameters or to create bullets in some other way?
Thanks in advance.
edit:
Is it really answered? I don't have any problems producing the bullet list, as described in those links but I'm having problems getting the layout correct. The indentation is like this:
text that go beyond the width
of the line.
And I want the "of the line" to at least start indented as far as the text after the bullet. That's what I try to achieve.
I'm suprised that there seems to be noone with this problem. I mean, bullet list can't be that uncommon in about-dialogs, FAQ etc and a bullet doesn't have to contain too much text to span more than one row and run into this problem.
Anyway, I got to solve it like this for now:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:id="#+id/ScrollViewTipsLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/TipsLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableLayout
android:layout_height="wrap_content"
android:id="#+id/TableLayout01"
android:layout_width="wrap_content"
>
<TableRow>
<TextView android:id="#+id/tvIngress"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#+string/tv_picking_content_ingress"
android:layout_span="2"
android:singleLine="false"
android:layout_weight="1"
/>
</TableRow>
<TableRow>
<TextView android:id="#+id/tvCleaningDot1"
android:layout_height="wrap_content"
android:text="•"
android:singleLine="false"
/>
<TextView android:id="#+id/tvCleaningFirst"
android:layout_height="wrap_content"
android:text="#+string/tv_picking_content_first"
android:layout_width="0dp"
android:layout_weight="1"
android:gravity="left"
android:singleLine="false"
/>
</TableRow>
<TextView android:id="#+id/tvCleaningDot2"
android:layout_height="wrap_content"
android:text="•"
android:singleLine="false"
/>
<TextView android:id="#+id/tvCleaningSecond"
android:layout_height="wrap_content"
android:text="#+string/tv_picking_content_second"
android:layout_width="0dp"
android:layout_weight="1"
android:gravity="left"
android:singleLine="false"
/>
</TableRow>
</TableLayout>
</RelativeLayout>
I use it to present static text in a bullet list so I don't bother to create the bullet + text dynamically in code. If anyone have any suggestion how to accomplish the same thing in a better way, please enlight me.
Btw, if going with the solution suggested in second link above:
android:text="<ol><li>item 1\n</li><li>item 2\n</li></ol>
The second, third etc. row in a bullet that span over more than one row won't get same indention as first line, which is quite ugly.
Thank you #Bjorn
You can also do something like bellow.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/point"
android:textAppearance="?android:attr/textAppearanceSmall"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Text Here"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textSize="14sp" />
</LinearLayout>
The way I solved this problem was by using a RelativeLayout and marginLeft. The marginLeft will put a blank margin between it and the previous item.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbarTrackVertical="#drawable/scrollbar_vertical_track"
android:scrollbarThumbVertical="#drawable/scrollbar_vertical_thumb"
android:scrollbarSize="12dip">
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10sp">
<TextView
android:id="#+id/body_text3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="Main paragraph of text, before the bulleted list"
android:textSize="15sp" />
<TextView
android:id="#+id/type1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="• First bullet"
android:textSize="15sp"
android:layout_below="#+id/body_text3"
android:layout_marginLeft="25dp" />
<TextView
android:id="#+id/type2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="• Second bullet"
android:textSize="15sp"
android:layout_below="#+id/type1"
android:layout_marginLeft="25dp" />
</RelativeLayout>
</ScrollView>
Just trying to point out the key answer of the question:
to create an bullet list, use TableLayout with two columns for each row. One column for TextView of a bullet and the other one for the text
to make text TextView fill the rest empty TableRow and indented at new line, set the weight to 1. You can set the bullet weight to zero or just simply not set the bullet weight and let it empty
based on my experience, changing width parameter do not affect the text and the bullet. So you can leave it empty or set it to anything you want.
Example:
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/bullet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/bullet"/>
<TextView
android:id="#+id/TextView01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="this is the text of a bullet list"/>
</TableRow>
</TableLayout>
I have a relative layout which looks like this:
Here is the code:
<?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="fill_parent"
>
<TextView
android:id="#+id/nameText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip"
android:layout_alignParentLeft="true"
android:text="Symbol"
/>
<TextView
android:id="#+id/priceText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip"
android:layout_toRightOf="#+id/nameText"
android:gravity="right"
android:text="100"
/>
<TextView
android:id="#+id/changeText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dip"
android:layout_toRightOf="#+id/priceText"
android:gravity="right"
android:text="1.3"
/>
</RelativeLayout>
How can I get the company name to line up next to the number 1.3?
Following up on Mayra's answer, here's one way to do it using layout_weight:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TableRow>
<TextView
android:id="#+id/left_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left|center_vertical"
android:padding="5dip"
android:layout_weight="0"
android:text="Code"
/>
<TextView
android:id="#+id/middle_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="right|center_vertical"
android:padding="5dip"
android:layout_weight="1"
android:text="Name of Company"
/>
<TextView
android:id="#+id/right_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip"
android:gravity="right|center_vertical"
android:layout_weight="0"
android:text="1.3"
/>
</TableRow>
</TableLayout>
It's not clear exactly what you want to have happen, but here are a few options:
If you want columns to be aligned across rows, you might consider using a TableLayout.
You can also use the "weight" atribute to affect what percentage of the screen each TextView takes up. If you assign a value of 1 on the left-most text view, and 0 on the other 2, this will cause the left text view to take up all the extra space, and thus push the middle text view to the right. This will probably cause the middle text view to look right aligned though. You could instead give the left one 20%, the middle one 50% and the right one 30% by assign 2, 5 and 3.
You could also just set an explicit size for the text views (in dpi), but this might be problamatic with different sized screens.
I agree with Mayra! Use the TableView, you'll get the formatting your looking for as well as keep almost all functionality of a ListView (scolling, and list oriented functionality)
