How can I place two views depending on their width?

In our project we have such a case: we have two textviews (let's say, #id/text_view_1 and #id/text_view_2). We should place them horizontally (#id/text_view_1 and then #id/text_view_2) if their width combined is less than the width of their parent or vertically (text_view_2 above text_view_1) if they are too wide.
Right now the best solution I've come up with looks something like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/parent"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/text_view_above_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true" />
<TextView
android:id="#+id/text_view_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/text_view_2_right"
android:layout_alignBottom="#+id/text_view_2_right"
android:layout_alignParentStart="true" />
<TextView
android:id="#+id/text_view_right_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/text_view_2_above"
android:layout_toEndOf="#+id/text_view_1" />
</RelativeLayout>
Here is the logic of toggling visibility of text_views
private void toggleVisibility() {
TextView textView1 = (TextView) findViewById(R.id.text_view_1);
TextView textViewAbove2 = (TextView) findViewById(R.id.text_view_above_2);
TextView textViewRight2 = (TextView) findViewById(R.id.text_view_right_2);
textView1.measure(0, 0);
textViewAbove2.measure(0, 0);
textViewRight2.measure(0, 0);
View parent = findViewById(R.id.parent);
parent.measure(0, 0);
if (textView1.getMeasuredWidth() + textViewRight2.getMeasuredWidth() < parent.getMeasuredWidth()) {
textViewAbove2.setVisibility(View.GONE);
textViewRight2.setVisibility(View.VISIBLE);
} else {
textViewRight2.setVisibility(View.GONE);
textViewAbove2.setVisibility(View.VISIBLE);
}
}
Is there a solution more "beautiful" and shorter than the one I've described? I guess there is a way to do it with ConstraintLayout instead of RelativeLayout but I'm not sure.
EDIT 1: probably I have to provide the result I want to see. Here is what an activity supposed to look like if both views are short:
And here is what it should look like if views are too long:

Take a look at FlexboxLayout.
Here is a solution using FlexboxLayout:
<com.google.android.flexbox.FlexboxLayout
android:id="#+id/parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:flexWrap="wrap">
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:text="This is a short string." />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:text="This is another short string." />
</com.google.android.flexbox.FlexboxLayout>
Using the same XML with a longer string for the first text view yields the following:

Solution:If you want to set TextView as per their width requirements then you will simply use LinearLayout as parent with width wrap_content and for both child TextViews also give width 'wrap_content'

try using wrap_content and put these child text views inside a parent LinearLayout , give wrap_content as width for both of the child textviews. It will place according to the content in those textviews.
If You want to put Views Horizontally --
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/parent"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal">
<TextView
android:id="#+id/text_view1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:id="#+id/text_view2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
If You want to put Views Vertically --
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/parent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/text_view1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:id="#+id/text_view2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>

Try using percentagelayout . This might help. For more details provide desired output.

Textview is not truncating the text

Following is my .xml file
<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="center_vertical" >
...
<TextView
android:id="#+id/tvAlternateRoad"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="#dimen/fancy_dashboard_max_speed_circle_strock_size"
android:gravity="start"
android:text="Via A11"
android:lines="1"
android:textColor="#808080"
android:textSize="#dimen/fancy_dashboard_lable_size" />
</TableRow>
I am calling the above .xml file in my main view .xml as following,
<RelativeLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.85"
android:gravity="end"
android:orientation="horizontal" >
<TableLayout
android:id="#+id/layAlternateRoute"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_margin="#dimen/fancy_dashboard_max_speed_circle_strock_size"
android:background="#drawable/bg_round_rect_alternate_route" />
</RelativeLayout>

I am displaying a view on the screen which has above TableRow element. I am setting this Textview tvAlternateRoad's text value at run time. Sometimes when Text is large then it is moving outside the view. I tried to truncate it using android:ellipsize="end" from some S.O. posts but it seems it is not working now a days.
Can somebody help me on this?

Give paddingRight to text view. Also, text view has width wrap content and no relation with any other view. So your text view width can exceed the rounded corner background image as per text length. So either give some maxWidth value or relate it to some other views.
Edit
I just made this xml:
<?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="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textview_Statu"
style="#style/text_view_login_style"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/more_txt3_margin_t"
android:background="#android:color/white"
android:ellipsize="end"
android:singleLine="true"
android:text="1234567890qwertyuiopasdfghjklzxcvbnm"
android:textColor="#color/blue_end" />
</LinearLayout>
In graphical view, It looks like this
Its working fine.

I have noticed that TextView will do different things with respect to wrapping and truncating depending on the container it's in. Try having the TableRow cell be, for instance, a FrameLayout. Then put your TextView inside the FrameLayout and see what happens.

Just use:
android:singleLine="true" and android:ellipsize="end"
and set a fixed width for your textview like "match_parent" or something in dp like "180dp" etc.
singleLine="true" needs your textview to have a fixed width which is not provided by "wrap_content".
A textview will only show ellipses at the end of its view's bounds and since you have set "wrap_content" your textview does not have any fixed bounds.

try this
tablelayout should be
<TableLayout
android:id="#+id/tbl"
android:layout_height="wrap_content"
android:layout_width="match_parent"
>
the remaining part should be
<TableRow
android:layout_height="wrap_content"
android:layout_width="match_parent"
>
<TextView
android:id="#+id/tvAlternateRoad"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:ellipsize="end"
android:maxLines="1"
android:minLines="1"
android:layout_marginRight="#dimen/fancy_dashboard_max_speed_circle_strock_size"
android:gravity="start"
android:text="Via A11"
android:layout_weight="1"
android:textColor="#808080"
android:textSize="#dimen/fancy_dashboard_lable_size" />

Ok, after long effort I have solve the issue my self.
Logic:
fetch the screen size programmatically
int screen_width = context.getResources().getDisplayMetrics().widthPixels;
then I used 42% of the screen_width as maxwidth of textView
((TextView)alternate.findViewById(R.id.tvAlternateRoad)).setMaxWidth((int)(screen_width*0.42));
I have also set below values in xml
android:ellipsize="marquee"
android:maxLines="1"

when adding views they go one below another even if width is wrap content

I have a Linear layout then programatically I'm adding some spinners and buttons and so on, but I have xml button Wrap content (width) and then on java I add spinner (or anything else) and it goes below this view even if both views are wrap content:
progBar = new ProgressBar(this);
pBarToca = new ProgressBar(this);
pBarToca.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
linToca = (LinearLayout) findViewById(R.id.tetoca);
linToca.addView(pBarToca);
and it's placed under the button of xml:
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" android:layout_marginTop="6dp"
android:id="#+id/tetoca">
<TextView style="#style/StylePartida"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/te_toca_jugar" />
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9" android:onClick="callJugar"
android:text="#string/jugar" />
</LinearLayout>
edit!!!!!!
I want textview on first line then on next line button + progressbar (for example)

You have android:orientation=vertical so the Views will be laid out starting at the top and going down.
If you want them to all be next to each other, remove that from your xml since the default orientation for a LinearLayout is horizontal. If you do this, you will obviously need to change the android:width to wrap_content for your TextView or else it will take up the entire screen.
After your comment, a RelativeLayout would work best here.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<TextView
style="#style/StylePartida"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/te_toca_jugar"
android:id="#+id/tvID" /> // give it an id
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
android:id="#+id/tetoca"
android:layout_below="#/id=tvID"> // place it below the TV
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9" android:onClick="callJugar"
android:text="#string/jugar" />
</LinearLayout>
</RelativeLayout>
Note the changes in the comments. Now when you add your progressbar to the LL, it should be next to the Button. You may need some changes but this should give you approximately what you want.

<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
android:id="#+id/tetoca">
<TextView style="#style/StylePartida"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/te_toca_jugar"
android:text="#string/te_toca_jugar" />
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9" android:onClick="callJugar"
android:text="#string/jugar" />
</LinearLayout>

In your textView you are matching the parent
android:layout_width="match_parent"
This will cause the textview to take up the entire width of the parent view.
android:layout_width="wrap_content"
and
android:orientation="horizontal"
android:orientation="vertical" will cause the elements to be stacked.
If you are using "horizontal" it's important not to have a child element with width matching parent.
EDIT:
After OPs change to question:
I have used a textview, two buttons and listview to give you an idea of how you can format it. There are many ways to achieve the same thing, this is one suggestion.
The internal linearlayout has a horizontal orientation (by default).
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="te_toca_jugar"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9"
android:text="jugar"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9"
android:text="jugar2"/>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/lv">
</ListView>
</LinearLayout>
</LinearLayout>

Android - List view with single choice radio buttons

I have a list view with 2 radio button items. When inflated it from a layout, it is happening to be scrollable even if there is a lot of space as shown below.
As shown in screenshot, I have 2 radio buttons.
1. Distance
2. Rating
But the "rating" radio button is not visible and I have to scroll to see it. Why is this happening. I tried to setting the layout height to wrap content, fill parent and match parent. But that didn't solve the problem. Any idea why is this happening?
here i am referencing the list view :
ListView radio_list = (ListView) view.findViewById(R.id.RadioList);
radio_list.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_single_choice,
radio_list_items));
radio_list.setItemsCanFocus(true);
radio_list.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
my xml:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >

android:layout_width="match_parent"
android:layout_height="wrap_content"

Your layout xml file is weird,
first of all you should simplify it :
there is no point of having one single element in a LinearLayout => it means the corresponding linear layout is useless.
second point : if there is 2 child in a linear layout, and the first one has a height of "match_parent" without any layout_weight set, the second one will be pushed out because there isn't any space left. ( its probably your problem here)
third point : your are using a relative layout as a linearlayout, proof is the android:orientation parameter you try to use on it. it is useless. position of relative layout childs are given by relative positioning between them. in your case you can use a LinearLayout with orientation horizontal instead of the RelativeLayout
best advise to help you : simplify your layout xml.

LinearLayout addView doesn't work properly

I'm having issues with the addView method from LinearLayout. I don't know why, but if I add three views only the first one is displayed. Here is the code:
Comment[] comments = posts[position].getComments();
LinearLayout layout = (LinearLayout)convertView.findViewById(R.id.post_list_item_comments);
layout.removeAllViews();
for(int i=0; i<comments.length; i++) {
View comment = inflater.inflate(R.layout.post_list_item_comment,null);
((TextView)comment.findViewById(R.id.post_list_item_comment_name)).setText(comments[i].getFrom().getName());
((TextView)comment.findViewById(R.id.post_list_item_comment_message)).setText(comments[i].getText());
layout.addView(comment,i);
}
I've tried with addView(comment) too, but with the same result.
This is the code of the View that I retrieve when to use the findViewById mehthod.
<LinearLayout
android:id="#+id/post_list_item_comments"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="40dip"
android:layout_below="#id/post_list_item_footer_text"
android:visibility="gone"/>
And this is the XML that I inflate:
<?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">
<View
android:id="#+id/post_list_item_comment_divider"
android:layout_width="fill_parent"
android:layout_height="1dip"
android:background="#drawable/divider"
android:layout_marginTop="2dip"
android:layout_marginBottom="2dip"/>
<ImageView
android:id="#+id/post_list_item_comment_photo"
android:layout_width="40dip"
android:layout_height="wrap_content"
android:layout_below="#id/post_list_item_comment_divider"
android:adjustViewBounds="true"/>
<TextView
android:id="#+id/post_list_item_comment_name"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toRightOf="#id/post_list_item_comment_photo"
android:layout_below="#id/post_list_item_comment_divider"
android:maxLines="2"
android:ellipsize="end"/>
<TextView
android:id="#+id/post_list_item_comment_message"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toRightOf="#id/post_list_item_comment_photo"
android:layout_below="#id/post_list_item_comment_name"
android:textSize="13sp"
android:maxLines="2"
android:ellipsize="end"/>
</RelativeLayout>

you do not declare the LinearLayout orientation... by default is Horizontal, try setting the orientation Vertical
<LinearLayout
android:id="#+id/post_list_item_comments"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="40dip"
android:layout_below="#id/post_list_item_footer_text"
android:visibility="gone"/>

Use the hierarchy viewer to check if there really is only 1 view added, or that you can see only one view. For instance, this line android:layout_below="#id/post_list_item_footer_text" might be troublesome if you repeat it? I don't know the expected behaviour for that...
