How can I make so that when an element is empty, it simply does not take any room on the screen?
For example on this XML :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent"
android:descendantFocusability="blocksDescendants">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="55dp"
android:orientation="horizontal"
android:layout_marginLeft="60dp"
android:weightSum="1">
<LinearLayout
android:layout_width="0px"
android:layout_height="match_parent"
android:orientation="horizontal"
android:layout_weight="0.8"
android:weightSum="1">
<Button
android:layout_width="10dp"
android:layout_height="10dp"
android:layout_gravity="center"
android:layout_marginRight="20dp"
android:background="#drawable/no_urgence"
android:id="#+id/urg"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:textSize="17sp"
android:id="#+id/TitreSav"
android:textColor="#color/FrozenBlue"
android:layout_gravity="center_vertical"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:textSize="12sp"
android:id="#+id/date"
android:textColor="#color/FrozenBlue"
android:layout_gravity="center_vertical"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
The TextView with id : date will sometimes be empty. When it's the case, I don't want it to take any room in my list (see the screenshot for an easier understanding, can't quite find the words in english)
(I want Hyj to be aligned with the small circle but the empty date is still here under)
I've already tried to set the Visibility to Gone or invisible but I still have the remaining blank space when the date is empty.
just set internal gravity for your LinearLayouts
android:gravity="center_vertical"
especially for parent of your "date" View

Let me explain i have a xml like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imgCircle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/img_circle" />
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/imgCircle"
android:layout_toEndOf="#id/imgCircle"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
<TextView
android:id="#+id/mapCurrentLocation"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="TextView1"
android:textColor="#color/lblTextColor"
android:textSize="#dimen/lblTextLarge"
android:textStyle="normal" >
</TextView>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="TextView2"
android:textColor="#color/lblHintColor2"
android:textSize="#dimen/lblTextMedium"
android:textStyle="normal" >
</TextView>
</LinearLayout>
</RelativeLayout>
And this gives me Image and TextViews next to it
But i want to accomplish something like this
that TextView Background is extended (padding maybe) at the half of the Rounded Image (behind it) so that it looks like its "part" of the image. Or I was thinking of Making a view with background white that goes behind TextView so that it looks that way. But wanted to ask here maybe if there is a better way to do this.
I hope i was clear in explaining this (That is why I added pictures).
I have tried to use demo with your xml file and you can check below code. I had to give static height and width of the ImageView to achieve result.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/imgCarCircle"
android:layout_alignTop="#id/imgCarCircle"
android:layout_marginLeft="30dp"
android:background="#color/colorAccent"
android:orientation="vertical"
android:paddingLeft="40dp">
<TextView
android:id="#+id/mapCurrentLocation"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="text1"
android:textStyle="normal"></TextView>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="text2"
android:textStyle="normal"></TextView>
</LinearLayout>
<ImageView
android:id="#+id/imgCarCircle"
android:layout_width="60dp"
android:layout_height="60dp"
android:src="#mipmap/ic_launcher_round" />
</RelativeLayout>
try these:
first solution: change this
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/imgCircle"
android:layout_toEndOf="#id/imgCircle"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
to this:
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_marginLeft="20dp" // or just figure your image width and set this programatically
android:layout_height="wrap_content"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
second solution: it to use AbsoluteLayout which is a bit hard to handle.
hello i am trying to wrap a textview that has a long text. but when i test it, it just goes beyond the screen. What im trying to do is it will go to the next line if the text is long and it automatically adjust the layout. I am using this in a listview.
i am referring to this old question Android TextView Text not getting wrapped, it works on him so i tried to implement it but it wont effect on mine. thanks for answering.
here's my XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:background="#e6e6e6"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp">
<LinearLayout
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:orientation="vertical" android:padding="4dip"
android:layout_weight="1">
<TextView
android:id="#+id/tv_reviewer_name"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceLarge"
android:text="Reviewer Name"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_marginTop="5dp"
android:id="#+id/tv_review_details"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceSmall"
android:text="Review"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:width="0dip"/>
</LinearLayout>
</LinearLayout>
UPDATE
here's my listview:
<ListView
android:divider="#android:color/transparent"
android:dividerHeight="2.0sp"
android:id="#+id/lv_reviews"
android:background="#f2f2f2"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
You can use the inputType to auto manage a multiline text.
<TextView
android:layout_marginTop="5dp"
android:id="#+id/tv_review_details"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceSmall"
android:text="Review"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:width="0dip"
android:inputType="textMultiLine"
/>
if i use listView or recyclerView, i well put the layout width match parent as mentioned below:
<LinearLayout
<!--change to match_parent-->
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" android:padding="4dip"
android:layout_weight="1">
try it once, hope this will help you.
problem solved. it turns out android studio didnt update my changes when i ran my app. i uninstalled the app and then run it again and it works perfectly.
When you are using Gravity in vertical orientation, you have to use layout_height=0dp & when you are using Gravity in Horizontal orientation then you have to use layout_width=0dp for every child of Linear Layout so that it can resize the layout by itself
<LinearLayout
android:background="#e6e6e6"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp">
<LinearLayout
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:orientation="vertical" android:padding="4dip"
android:layout_weight="1">
<TextView
android:id="#+id/tv_reviewer_name"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceLarge"
android:text="Reviewer Name"
android:layout_width="wrap_content"
android:layout_height="0dp" />
<TextView
android:layout_marginTop="5dp"
android:id="#+id/tv_review_details"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceSmall"
android:text="Review"
android:layout_height="0dp"
android:layout_width="match_parent"/>
</LinearLayout>
</LinearLayout>
I'm having a lot of trouble getting my ScrollView to function properly. I'm using a Master-Detail design. The Master scrolls, since it's a listView. The Detail when selected will display the scrollbar implemented in my XML for a couple seconds when the Activity is inflated before disappearing (Stackoverflow won't allow me to post the screenshot of the error since this is my first post)
When I try to scroll the Detail Activity with touch input nothing happens. I've tried copying and pasting Mel's solution to what seems like an identical problem in the post at ScrollView doesn't work. I've also tried every conceivable combination of match_parent and fill_parent for the parent, child, and ScrollView itself. Any help is appreciated. My XML code is below:

I found a solution! Instead of trying to apply the formatting to the Activity XML itself, I cut and pasted it into one of the Activity's Fragment XMLs, which didn't have a frameLayout. Because of this change it now scrolls perfectly while maintaining the title bar on top throughout the scroll, exactly the behavior that I wanted. I've posted the final code below. If you have a solution that would still allow me to use a scrollView inside a FrameLayout though I'd be more than happy to see it for future reference. Thank you for your help!

Your goal is to use the maximal screen size for the ImageView and then scroll down to the (at first invisible) TableLayout? Thats afaik not possible. When you set android:layout_height="fill_parent" on ImageView it uses the the maximum possible (in your example all of the screen size) space. So no TableLayout is rendered and there is no need for scrolling. You should set the android:layout_height="wrap_content" in the ImageView.
Some notes on the source code:
Use match_parent instead of fill_parent. It's renamed since API Level 8
You have a useless android:layout_below="#id/picture" in the TableLayout. May an artifact from a previous version with RelativeLayout?
Remove the namespace definitions in the TableLayout
I would like to obtain this layout for an Android app for mobile phones:
Icon - Object1
List with entries related to Object1
Icon - Object2
List with entries related to Object2
So far I have used the following layout tree (edited graphically with the editor in Android Studio):
Root-LinearLayout
Vertical LinearLayout
Horizontal LinearLayout with icon and text
ListView
Vertical LinearLayout
Horizontal LinearLayout with icon and text
ListView
May be this is not the best way to organize such layout (may be I should use lists with header, but suggestions very welcome), however it can be a good case for understanding deeper how ListView works.
This is the graphical layout generated:
the blue row corresponds to the first LinearLayout. As you can see from the second screenshot that follows, the second list goes all the way down to Hell, bringing me with her. Is there any way to make the lists respect the wrap_content+ weight behaviour?
The XML code follows. I have tried several combos (both reasonable and unreasonable) of layout:weights but none works. I also tried to set the min-width of the first LinearLayout (the hidden one), but nothing changes.
Could you please help me?

It should work if you put your ListViews inside of the child LinearLayouts which hold the LinearLayout that has the TextView and ImageView. You also should be using "0dp" for the height when using weight with a vertical layout.
Something like this, I believe, should work
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:gravity="center_vertical"
android:minHeight="50dp"
android:layout_weight=".2">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView15"
android:src="#drawable/abc_ic_menu_share_mtrl_alpha" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Object1"
android:id="#+id/textView24"
android:textSize="26dp"
android:paddingLeft="10dp" />
</LinearLayout>
<ListView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:id="#+id/listView2"
android:layout_weight=".8" />
</LinearLayout>
Note the other changes: I gave the inner-LinearLayout an arbitrary weight of ".2" then the ListView a weight of ".8". And, of course, set the height to "0dp". You may need to play with those weights a bit but I think doing something like that for both first child LinearLayouts should get you close.
That may get your current layout to work but using headers and/or an ExpandableListView may be a better option.
I have a ListView that is populated with rows. These rows come from an XML file that looks like:
<?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"
android:paddingLeft="8dip"
android:weightSum="100">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/columnA"
android:layout_weight="30"
android:layout_gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/columnB"
android:layout_weight="30"
android:layout_gravity="center"/>
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:src="#drawable/icon"
android:id="#+id/columnC"
android:layout_weight="10"
android:layout_gravity="center"
>
</ImageView>
<CheckBox
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/columnD"
android:layout_weight="30"
android:layout_gravity="center"/>
The problem is that I want the columnC item and columnB item to be very close together, so that my rows are equally spaced out in three parts, i.e.: columnA, (columnB+columnC) and then columnD. I tried to achieve this by using layout_weight as you can see, however the above code seems to have the opposite effect. columnA and columnB are very squished on the left, column C seems to be floating in a large space on its own, and then columnD is located close to columnC, with too much space on its right. What am I doing wrong? :s
Give this a try. You can basically figure how much space each view will "want" by weight/total weight. You don't have to try to make them equal 100.
<?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"
android:paddingLeft="8dip"
android:weightSum="100">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/columnA"
android:layout_weight="2"
android:layout_gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/columnB"
android:layout_weight="1"
android:layout_gravity="center"/>
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:src="#drawable/icon"
android:id="#+id/columnC"
android:layout_weight="1"
android:layout_gravity="center"
>
</ImageView>
<CheckBox
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/columnD"
android:layout_weight="2"
android:layout_gravity="center"/>
I would think that you want columnC and columnB to have the same weight, but you have it set with them different.
Try
columnA:weight=2
columnB:weight=1
columnC:weight=1
columnD:weight=2
I have very limited experience with the weight attribute but I think this is how you can get your desired result.
If you're still having trouble with it, may help us help you if you can post a screen shot of how it looks, and how you want it to look.
