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

Question

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.

[ |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!

[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 :)

What you have to understant is that, the content is dynamically retrieve from a WebService. Thus, I don't know in adavance how large is the destination name, so I definitely need to have the "Destination name" TextView dynamic (in terms of width), and I don't want this one to "hide" the right TextView. — louloox, Sep 06 '14 at 18:00

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:id="@+id/rl_parent"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:background="#348D63">

        <TextView
            android:id="@+id/tv_1"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:background="#BD160B"
            android:gravity="center_vertical"
            android:maxLines="1"
            android:paddingLeft="10dp"
            android:paddingRight="10dp"
            android:text="Elsau Elsau Elsau Elsau Elsau Elsau Elsau"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/tv_2"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_toRightOf="@+id/tv_1"
            android:gravity="center_vertical"
            android:minWidth="50dp"
            android:paddingLeft="10dp"
            android:paddingRight="10dp"
            android:text="[11:30 14:23]"
            android:textStyle="bold" />

    </RelativeLayout>

    <!-- Rest of the layout -->

</LinearLayout>

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.

Hi valbertos, Thank you, but I tried both RelativeLayout your proposed, but the first one doesn't let the right TextView visible if the left TextView is too long. The second RelativeLayout has a fixed width for the left TextView, which is not ok since it has a dynamic size. — louloox, Sep 06 '14 at 17:52
I didn't understand you well. Try again, I've modified my question ;) — Víctor Albertos, Sep 06 '14 at 19:09
Well, actually it seems you understood what I meant :) I want to resize the width of the left TextView according to the right one, so that the right is always fully-displayed on 1 line. But I thought I could do that from the xml View. I'll try your solution soon :) Thanks. — louloox, Sep 06 '14 at 20:18
Yes, it's working :) Thanks a lot! Any idea if it's do-able directly with the xml View ? I have the feeling that it can be done in HTML/css (1 table, 2 columns, 1st ellipsis, 2nd nowrap). Anyway, thanks a lot! Great forum =) Cheers! — louloox, Sep 06 '14 at 20:32
You're welcome! I don't think it could be achieved just from layout because the layout system doesn't support such complex calculations. :) — Víctor Albertos, Sep 06 '14 at 22:29

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>

Hi pomber, Well, thank you, it was also my first idea, but it's not working: if the left TextView is too long, the right one is not visible... – louloox Sep 06 '14 at 17:56
