Problems inflating a custom LinearLayout into a custom class that extends LinearLayout

I'm trying to inflate a LinearLayout containing a few different Textviews and a Button into a custom class that extends LinearLayout.
Here is the XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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_height="wrap_content"
android:background="#173BBC"
android:gravity="center_vertical"
android:minWidth="200dp"
android:minHeight="40dp"
android:orientation="horizontal"
android:padding="10dp"
android:visibility="visible">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:layout_weight="1"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/textView12"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/compte" />
<TextView
android:id="#+id/textViewCompteT"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="TextView" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/textView14"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/valeur" />
<TextView
android:id="#+id/textViewValeurT"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="TextView" />
</LinearLayout>
</LinearLayout>
<Button
android:id="#+id/buttonDeleteTransaction"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:drawableTop="#android:drawable/ic_menu_delete"
android:minWidth="48dp"
android:paddingLeft="30dp"
android:paddingTop="10dp"
android:paddingRight="30dp"
android:paddingBottom="0dp"
android:textSize="0sp"
app:cornerRadius="20dp"/>
</LinearLayout>
And here is my class: (please don't take care about the names of the variables, they are bad ;) )
public class TransactionTwo extends LinearLayout {
private Context context;
private LinearLayout container;
private LinearLayout content;
private LayoutParams layoutParams;
private LayoutParams contentLayoutParams;
public TransactionTwo(Context context, Activity parent){
super(context);
activity = (Details) parent;
//here i define my layouts to make them have the fine shape.
layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(10, 10, 10, 10);
contentLayoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
this.setLayoutParams(layoutParams);
this.setOrientation(LinearLayout.VERTICAL);
this.setBackgroundColor(Color.RED);
container = new LinearLayout(context);
container.setOrientation(LinearLayout.VERTICAL);
container.setLayoutParams(contentLayoutParams);
}
public void createViews(){
//here i try to force the display of the inflated layout (which doesn't appear on screen)
content = (LinearLayout) inflate(context, R.layout.modele_transaction2, container);
content.setVisibility(View.VISIBLE);
content.setLayoutParams(contentLayoutParams);
container.setMinimumHeight(100);
this.addView(container);
//then i find a few textviews and set their text (which works correctly even if i can't see it)...
}
#Override
protected void onLayout(boolean b, int i, int i1, int i2, int i3) {
}
Everything seems to work correctly (at least Android doesn't raise any error), but the only trouble is that I can see the LinearLayout "TransactionTwo" having the size of the LinearLayout that I inflate in it, but I can't see the inflated one... And when I ask for the height of content and container it always answer 0. So it is as if the inflated layout was only giving its size without appearing...
If anyone knows what is wrong in my code, that would be really appreciated because I'm stucked on this issue for a long time now ;)
Thank you!

In fact it might have been a bug of Android Studio, because I made a copy of my java class and it worked this time...

Unwanted spaces in recyclerview items in android

I have spaces on recyclerview of my app and i don't know why are there because i have done the samething using the recyclerview and this adapter and did not added unwanted space...but now it is.

Here goes the screenshots of the unwanted spaces on the recyclerview

change your recyclerview Height from android:layout_height="match_parent" to
android:layout_height="wrap_content".
and why you are giving scrolling behavior to Your relative layout ??? RecyclerView already hve that!

There is no problem with your recyclerview, you should make changes in R.layout.rv_model file. You have set android:fitsSystemWindows="true" property to<TextView>.
Most of the time, your app won’t need to draw under the status bar or the navigation bar, but if you do: you need to make sure interactive elements (like buttons) aren’t hidden underneath them. That’s what the default behavior of the android:fitsSystemWindows=“true” attribute gives you: it sets the padding of the View to ensure the contents don’t overlay the system windows.
A few things to keep in mind:
fitsSystemWindows is applied depth first — ordering matters: it’s the first View that consumes the insets that makes a difference
Insets are always relative to the full window — insets may be applied even before layout happens, so don’t assume the default behavior knows anything about the position of a View when applying its padding
Any other padding you’ve set is overwritten — you’ll note that paddingLeft/paddingTop/etc is ineffective if you are using android:fitsSystemWindows=”true” on the same View
And, in many cases, such as a full screen video playback, that’s enough. You’d have your full bleed view with no attribute and another full screen ViewGroup with android:fitsSystemWindows=”true” for your controls that you want inset.
Or maybe you want your RecyclerView to scroll underneath a transparent navigation bar — by using android:fitsSystemWindows=”true” in conjunction with android:clipToPadding=”false”, your scrolling content will be behind the controls but, when scrolled to the bottom, the last item will still be padded to be above the navigation bar (rather than hidden underneath!).
Check if you want more information about android:fitsSystemWindows

Your item layout is filling one length of your screen each.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/tools"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" <!-- Here needs to be wrap_content -->
android:orientation="vertical">
<android.support.v7.widget.CardView
android:id="#+id/cl_CardView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
And remove android:fitsSystemWindows="true" from the TextViews because they don't need to fit the system window.

how to overlap a layout with image view and text over the other layout as a stack/pile

I am in a weird situation in my existing project. In my project i want to inflate one layout over the other as a stack dynamically. At present in my project i managed to show the layouts one below the other vertically by appending them, this approach has been chosen by me because even though i am trying to show it as stack only one image is appearing at the front during runtime instead of a bunch. In order to understand my problem please go through the following image links and code

Please go through my code and let me know where am i going wrong and let me know if i am unclear anywhere

Change the margin top to make views come down a bit
for(int j=0; j<=5; j++)
{
view=layoutInfralte.inflate(R.layout.newdeels, null);
LinearLayout.LayoutParams lp=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
lp.setMargins(left,5*j, right, bottom);
view.setLayoutParams(lp);
views.add(view);
}
for(int i = 0; i<views.size(); i++)
{
imageGallery.addView((View) views.get(i));
}

Github : Material Recent Layout
Usage
RecentsList recents = (RecentsList) findViewById(R.id.recents);
recents.setAdapter(new RecentsAdapter() {
#Override
public String getTitle(int position) {

}
#Override

#Override
public int getCount() {
return 10;
}
}
Note
You need to modify as per your requirement.

Try FrameLayout in your parent layout. Set different margins in child views to achive an effect of stack.
Child views are drawn in a stack, with the most recently added child on top

check out : github.com/kikoso/Swipeable-Cards
As per your response :
hi thank you for your response ur response actually worked. But now i am dealing with another situation where-in i would like to update details based on swipe for eg: if a card is swiped right it should be gestured as like where as if a card is swiped left it should be gestured as dislike so how to actually code these swipe gestures can you please help me out
#ashwin for that you should have a like and dislike drawable or a custom view.
card.setOnCardDimissedListener(new CardModel.OnCardDismissedListener() {
#Override
public void onLike() {
Log.d("Swipeable Card", "I liked it");
}
#Override
public void onDislike() {
Log.d("Swipeable Card", "I did not liked it");
}
});
Use above snippet to show or hide the view of like or dislike in respective methods that is onLike() and onDislike().
Edit 1:
I figured out the problem what you are facing, If you are simply implementing the Sample Code. Then it clearly shows that CardContainer has SimpleCardStackAdapter as adapter and CardModel are added to it using new operator. Except the last element of CardModel that is added separately and cardModel Listener is applied on last element only. If you want to apply it on all elements. Then you should have to add the elements to SimpleCardStackAdapter by ArrayList of CardModel.

Making Recyclerview Fixed Height and Scrollable

SOLVED CHECK ANSWER BELOW...
So I am trying to create a comments functionality for my Android app and I want to display the comments inside a recyclerview and then have a button and textview below the recyclerview to add comments. I want to have the recyclerview a certain height and make it scrollable if there are lots of comments because I dont want the users to have to scroll down the screen to find the add button.
I couldn't get it to work so I was wondering if anyone else had that issue.
I have all the adapter and everything set up, I am just having trouble with the recyclerview.
Thanks.
I prob was not clear on what I was trying to accomplish. I am trying to create a cardview where it will display all the comments and the ability to add a new comment. The recyclerview will take up approx 80% of the height and then the last 20% is for the edittext and button.

The second and first comment are being cut off.

So what my problem was that for some reason, Recyclerview didnt wrap_contents. I did some research (thanks stackoverflow) and found out a lot of people were having this issue and they posted solutions for this issue.
Basically, I had to use a customized linearlayoutmanger to fix the issue.
I will post the solution they posted and links to their questions. thanks for whoever tried to help, I appreciate it.
This is the extra file I needed. And then I had to set my recyclerview to use this layout instead of the default one.
public class MyLinearLayoutManager extends LinearLayoutManager {
public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
super(context, orientation, reverseLayout);
}
private int[] mMeasuredDimension = new int[2];
#Override
public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
int widthSpec, int heightSpec) {
final int widthMode = View.MeasureSpec.getMode(widthSpec);
final int heightMode = View.MeasureSpec.getMode(heightSpec);
final int widthSize = View.MeasureSpec.getSize(widthSpec);
final int heightSize = View.MeasureSpec.getSize(heightSpec);
int width = 0;
int height = 0;
for (int i = 0; i < getItemCount(); i++) {
measureScrapChild(recycler, i,
View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
mMeasuredDimension);
if (getOrientation() == HORIZONTAL) {
width = width + mMeasuredDimension[0];
if (i == 0) {
height = mMeasuredDimension[1];
}
} else {
height = height + mMeasuredDimension[1];
if (i == 0) {
width = mMeasuredDimension[0];
}
}
}
switch (widthMode) {
case View.MeasureSpec.EXACTLY:
width = widthSize;
case View.MeasureSpec.AT_MOST:
case View.MeasureSpec.UNSPECIFIED:
}
switch (heightMode) {
case View.MeasureSpec.EXACTLY:
height = heightSize;
case View.MeasureSpec.AT_MOST:
case View.MeasureSpec.UNSPECIFIED:
}
setMeasuredDimension(width, height);
}
private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
int heightSpec, int[] measuredDimension) {
View view = recycler.getViewForPosition(position);
if (view != null) {
RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
getPaddingLeft() + getPaddingRight(), p.width);
int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
getPaddingTop() + getPaddingBottom(), p.height);
view.measure(childWidthSpec, childHeightSpec);
measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
recycler.recycleView(view);
}
}
}
After that. Change this:
mProductsRecyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
To this:
mRecyclerView.setLayoutManager(new MyLinearLayoutManager(getApplicationContext(),1,false));
Three new paramets(Context, int Orientation, boolean reverse);
basically, i put 1 for orientation so it shows vertiacally, and false for revers so it shows up how it is ordered in my List.

Nested Recycler view height doesn't wrap its content
Nested Recycler view height doesn't wrap its content
Thanks once again guys. Hope this helps someone else

Add this code in your activity, will set the height of your recycler view to the 90% of user's screen window.
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int a = (displaymetrics.heightPixels*90)/100;
recylcerView.getLayoutParams().height =a;
and your comment layout below the your recyclerView
like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/mudit"
>
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="5dp"
android:scrollbars="vertical" />
</LinearLayout>
<RelativeLayout
android:layout_below="#+id/mudit"
android:id="#+id/rl_commentWrap"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<EditText
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:ems="10" />
<Button
android:id="#+id/plusButton"
style="android:buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:text="Send"
android:textColor="#FFFFFF"
android:translationZ="5dp" />
</RelativeLayout>
</RelativeLayout>

In my situation I had a DialogFragment, in which there are 2 recyclers and 2 horizontal linear layouts with 2 buttons.
Dialog from top to bottom looks like this:
RecyclerView A
Horizontal linear layout X with 2 buttons
RecyclerView B
Horizontal linear layout Y with 2 buttons
On top of that both recyclers size is dynamic.
Recycler A size can change based on user swipes in both recyclers.
Recycler B size can change based on its item click listener.
What I wanted to achieve was to cut the Dialog from top to bottom
and have each of those four views its constant part of the Dialog height.
What worked was to divide it first to 2 separate relative layouts, say lTOP and lBottom. Set lTOP alignParentTop, lBottom alignParentBottom and layout_below lTOP.
Both of them width match_parent, height wrap_content.
Then in each of them create 1 relative (say lINTop) and 1 linear (say lINBottom) layouts. lINTop has recycler, lINBottom has 2 buttons.
Set both lINTop lINBottom width match_parent, height wrap_content.
Set lINTop alignParentTop, lINBottom alignParentBottom and below lINTop.
Set lINTop orientation vertical, lINBottom orientation horizontal.
Set recyclers width match_parent, height wrap_content.
Then i putted this all inside single relative layout with width/height wrap_content and orientation vertical.
Then this inside scrollview with width/height match_parent and orientation vertical.
Then needed a little code magic for setting up recycler in onCreateView:
For Recycler A:
private void setupRecyclerA() {
// use a linear layout manager
RecyclerView.LayoutManager layManUS = new LinearLayoutManager(setupActivity().get());
recyclerA.setLayoutManager(layManUS);
recyclerA.addItemDecoration(new DividerItemDecoration(
setupActivity().get(), LinearLayoutManager.VERTICAL));
recyclerA.setNestedScrollingEnabled(true);
// use this setting to improve performance if you know that changes
// in content do not change the layout size of the RecyclerView
recyclerA.setHasFixedSize(true);
}
For Recycler B:
private void setupRecyclerB() {
// use a linear layout manager
RecyclerView.LayoutManager layManUS = new LinearLayoutManager(setupActivity().get());
recyclerB.setLayoutManager(layManUS);
recyclerB.addItemDecoration(new DividerItemDecoration(
setupActivity().get(), LinearLayoutManager.VERTICAL));
recyclerB.setNestedScrollingEnabled(true);
// set fixed height
DisplayMetrics displaymetrics = new DisplayMetrics();
setupActivity().get().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
// set height to 30 percent of dialog
int a = (displaymetrics.heightPixels*30)/100;
recyclerB.getLayoutParams().height =a;
// use this setting to improve performance if you know that changes
// in content do not change the layout size of the RecyclerView
recyclerB.setHasFixedSize(true);
}
I didnt invented it, I just combined solutions from many different Stack Overflow questions which I dont even remember now, sorry and thanks to the Creators.

I had a similar problem and solved it with RelativeLayout. I have this layout:
I wanted the top and bottom cardview to stay in place while scrolling the central recyclerView. Tried with LinearLayout and ConstraintLayout but didn't work, the bottom CardView only was shown when I scrolled to the end of the recycler.
This is my code, notice the layout_above, layout_below, and layout_alignParentBottom attributes:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/grisMasOscuro">
<androidx.cardview.widget.CardView
android:id="#+id/cv1"
android:layout_width="match_parent"
android:layout_height="50dp" >
<!-- cardview content -->
</androidx.cardview.widget.CardView>
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/cv3"
android:layout_below="#id/cv1">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/myRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</androidx.cardview.widget.CardView>
<androidx.cardview.widget.CardView
android:id="#+id/cv3"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true">
<!-- cardview content -->
</androidx.cardview.widget.CardView>
</RelativeLayout>

I found another solution.
If you will wrap recyclerview in RelativeLayout, it will solve the problem easily.
Thanks.

2 TextViews, left with ellipsis, right with nowrap, single line

It's the first time I post on this forum, hope it's gonna be fine :)
I'm developping an Android App for public transportation in my city.
Here is what I have
[ |short destination ||next departure| ]
[ |way too long dest...||next departure| ]
Here is what I want:
[ |short destination||next departure| ]
[ |way too long dest...||next departure| ]
Here is a more complete example: s28.postimg.org/5gejnvfd9/actual2.png
Weird coloured backgrounds are just here to easily identify layouts/textviews. You can also ignore the brown line (which is ok).
Basically, I want to have the destination [red background] which have a variable length, and on its right, I want the first departure time [green background]. Everything on one line.
I need to always have the first departure information fully displayed (nowrap). The destination could be wrapped with an ellipsis (...).
[Optional question, how to replace the ellipsis '...' with '.' ?]
Here is the best working code I have so far:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/txtTitleDestination"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/txtTitleFirstDeparture"
android:background="#FF0000"
android:ellipsize="end"
android:maxLines="1"
android:padding="0dp"
android:scrollHorizontally="true"
android:textSize="18sp"
android:textStyle="bold" />
<TextView
android:id="#+id/txtTitleFirstDeparture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="0dp"
android:layout_marginRight="0dp"
android:layout_alignParentRight="true"
android:background="#00FF00"
android:ellipsize="none"
android:maxLines="1"
android:padding="0dp"
android:textSize="18sp"
android:textStyle="bold"
/>
</RelativeLayout>
I've tried TableLayout and LinearLayour instead of the RelativeLayout, but with no success :(
Any idea how I could do that?
Thanks in advance!
Louloox
[SOLVED]
Just have to lightly modify the valbertos answer:
titleDestination.post(new Runnable() {
#Override
public void run() {
int widthTextViewDeparture = measureTextWidthTextView(titleFirstTime, pContext);
int widthTextViewDestination = titleDestination.getWidth();
int widthTextViewParent = rl_parent.getWidth();
if(widthTextViewDestination + widthTextViewDeparture > widthTextViewParent) {
titleDestination.setWidth(widthTextViewParent - widthTextViewDeparture);
titleDestination.setEllipsize(TruncateAt.END);
titleDestination.setHorizontallyScrolling(true);
}
}
});
Setting the Ellipsis only if necessary makes the text properly truncated.
Before:
Lingolsheim Thiergaten --> Lingolsheim... [1'23"] 21h23
With the modification:
Lingolsheim Thiergaten --> Lingolsheim Thi... [1'23"] 21h23
Thanks again :)

You don't need do it programmatically, ConstraintLayout is a magic!
Just use this code
app:layout_constraintHorizontal_bias="0" align view left
app:layout_constrainedWidth="true" to wrap left text
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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="match_parent"
android:layout_height="wrap_content"
android:padding="8dp">
<TextView
android:id="#+id/leftText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:maxLines="1"
app:layout_constrainedWidth="true"
app:layout_constraintHorizontal_bias="0"
app:layout_constraintEnd_toStartOf="#id/rightText"
app:layout_constraintHorizontal_chainStyle="packed"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:text="|short destination|" />
<TextView
android:id="#+id/rightText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/leftText"
app:layout_constraintTop_toTopOf="parent"
tools:text="|next departure|" />
</androidx.constraintlayout.widget.ConstraintLayout>
Here is result

I found a way to do it using Linear Layout, the trick is not to forget width="wrap_content" for the linearLayout, hope it can help.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal">
<TextView
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ellipsize="end"
android:singleLine="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true" />

To do what you are asking for, you must adjust the width of the first view dynamically based on the text width of the second view.
//Code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
final TextView tv_1 = (TextView) findViewById(R.id.tv_1);
tv_1.post(new Runnable() {
#Override
public void run() {
View rl_parent = findViewById(R.id.rl_parent);
TextView tv_2 = (TextView) findViewById(R.id.tv_2);
int widthTextView2 = measureTextWidthTextView(tv_2);
if(tv_1.getWidth() + widthTextView2 > rl_parent.getWidth()) {
tv_1.setWidth(tv_1.getWidth() - widthTextView2);
}
}
});
}
private int measureTextWidthTextView(TextView textView) {
int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(getScreenWidth(), View.MeasureSpec.AT_MOST);
int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
textView.measure(widthMeasureSpec, heightMeasureSpec);
return textView.getMeasuredWidth();
}
private int getScreenWidth() {
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
Point size = new Point();
display.getSize(size);
return size.x;
}
//Layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="300dp"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout

android:layout_width="match_parent"

Use android:maxLines="1" instead of android:singleLine="true" to get rid off the ugly dots -as I did in my example.
Also, I recommend you to use include for the "time" section, instead of repeating the TextViews twice. I’ve just done it like that to keep simple the example.

Maybe you should use a LinearLayout instead of RelativeLayout and use the layout_weight attribute.
<LinearLayout android:orientation="horizontal" ...>
<TextView android:id="#+id/txtTitleDestination" android:layout_width="wrap_content" ... />
<TextView android:id="#+id/txtTitleFirstDeparture" android:layout_width="0dp" android:layout_weight="1" ... />
</LinearLayout>
