Hello I am trying to get text to display like it does in terminal or cmd. And by that I mean a window of text that with each input makes a new line and then displays the bottom line of the TextView, and there would be a set amount of lines always on the screen.
It sounded easy to do, but now that I started I'm not sure how to do it.
I tried putting a TextView in a ScrollView like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:weightSum="100" >
<ScrollView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1">
<TextView android:id="#+id/tv1"
android:layout_width="wrap_content"
android:minLines="11"
android:maxLines="11"
android:layout_height="wrap_content"/>
</ScrollView>
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="10"
android:onClick="buttonclick"
android:text="Button" />
</LinearLayout>
and then
sss=et1.getText().toString();
tv1.append("\n"+sss);
to add new lines
This all works but I really have no idea how to make the TextView go to the bottom, right now it just cuts off when I hit the max number of lines.
I definitely don't expect anyone to write my program for me. I am here to learn
Thanks for your time!
Call fullScroll(View.FOCUS_DOWN) on the ScrollView after appending the text.

I have created this, with 1 webview and 1 textview (tried also edittext) and a scrollview, but in the preview it explains all lines, when i launch it explain only 1 line. i tried to rmeove scrollview, webview...nothing...how can i do? Thank you

</LinearLayout>
</ScrollView>
Preview on Android Studio
Preview on my Phone/Emulator
In strings.xml you must escape all ' of testonavi_spawnby \', for example: ...all\'Avamposto...
Take a look into the documentation for String resources.
Edittext height is given as 126dp. You'll not be able to see 30 lines in it. so make the layout_heigh of the edittext as "wrap_content". This will make the edittext dynamic. As the total content is in scrollview, you'll still be able to scroll and see the complete content
Did you try using
android:minLines=10
where 10 is the number of lines you want it to appear.
Since you have set the android:width="match_parent" maybe its going beyond the view change it to android:layout_width="wrap_parent".
Change the code to:
<TextView
android:id="#+id/testo"
android:layout_width="wrap_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:minLines="10"
android:text="#string/testonavi_spawn"
android:textSize="15sp" />
NOTE: Always use a TextView to display the text and EditText to edit any texts.
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.
I would like to align two buttons on the bottom of a relative layout that is wrapped inside of a linear layout.
I am unable to get the view favorites button to be on top of the search button. There is a big space as you can see in this image:
Here is my code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:text="#string/SearchRestaurantsCity"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/tvRestaurantSearchCity" />
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/etRestaurantSearchCity" />
<TextView
android:text="#string/SearchRestaurantsState"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/tvRestaurantSearchState" />
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/etRestaurantSearchState" />
<TextView
android:text="#string/SearchRestaurantsCategories"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/tvRestaurantSearchCategories" />
<Spinner
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/spRestaurantSearchCategories" />
<RelativeLayout
android:id="#+id/InnerRelativeLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true">
<Button
android:text="#string/btnViewFavoriteRestaurants"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/btnViewFavoriteRestaurants"
style="#style/ButtonText"
android:padding="5dp"
android:layout_below="btnSearchRestaurants" />
<Button
android:text="#string/btnSearchRestaurants"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/btnSearchRestaurants"
style="#style/ButtonText"
android:layout_alignParentBottom="true"
android:padding="5dp" />
</RelativeLayout>
There are 2 things wrong with the XML.
For starters, you can't refer to the button btnSearchRestaurants before it's defined.
Secondly, you've defined btnSearchRestaurants to align-parent-bottom, and then tried to define that btnViewFavoriteRestaurants would be below that button. It should be above it (as per your description).
If you're trying to put the first button I can see inside RelativeLayout, I'd try to change the following line:
android:layout_below="btnSearchRestaurants" />
for this one:
android:layout_above="#+id/btnSearchRestaurants" />
Part of the space is reserved for all the elements of the layout I can see inside the LinearLayout,and the + is because the button btnSearchRestaurants is below so it is not created yet
I think the problem is at
android:layout_below="btnSearchRestaurants"
It should be
android:layout_below="#id/btnSearchRestaurants"
In your xml code I think you should correct this line
android:layout_below="btnSearchRestaurants"
as you want it to be above the Search Restaurants button it should be
android:layout_above="#id/btnSearchRestaurants"
I changed below to above for obvious reasons (you want it above the other button not below it) and added #id/ because you will be searching for the button id.
I am implementing listview with 2 textviews , and for reference used Basic Layout and Formatting
Instead of stock names which are short i am using long text, so when i use a long text, it overlaps with the second .
So how to get it right, so that the 2 textviews don't overlap each other.
You can used following code to solve your problem:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="1">
<TextView
android:layout_width="0dp"
android:layout_height="fill_parent"
android:id="#+id/ticker_symbol"
android:text="sdasd sadas"
android:layout_weight=".5"/>
<TextView
android:layout_width="0dp"
android:layout_height="fill_parent"
android:id="#+id/ticker_price"
android:text="dfsd"
android:layout_weight=".5"
android:gravity="right" />
</LinearLayout>
Output:
To avoid overlapping, you could set the second textview to align to right (android:layout_toRightOf).
For example:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:id="#+id/ticker_symbol"
android:layout_alignParentLeft="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:id="#+id/ticker_price"
android:layout_toRightOf="#id/ticker_symbol"
android:layout_alignParentRight="true" />
</RelativeLayout>
I guess you mean due to long length of text it goes to next line or on next TextView
So i suggest you to use textView property android:ellipsized="end" and also use android:single_line="true" instead this you can directly specify the maxline=1
I'm not sure with names spelled correctly so check while typing
<TextView
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:id="#+id/ticker_symbol"
android:ellipsezed="end"
android:singe_line="true"
android:layout_alignParentLeft="true" />
Hope this explanation woks for you let me know..
I have a problem with designing an UI Android activity. There are two blocks of misplaced graphics on the left and right of the activity - they are two lines just bellow the titlebar with 1px height and about 5-10px width. They cause buttons to break at their left and right parts. I cannot figure out what the problem is. I am using Eclipse with Android SDK 0.9.9. The lines appear not only with the emulator but in a HTC Wildfire (Android 2.1). These lines are also visible in a newly created Android project (HelloWorld).
Sorry, but I was not allowed to post images, being too new here :)

Funny, I also had the ListView dividers disappearing when scrolling and during the hunt I found the code here:
Disappearing dividers in Spinner drop-down list
It not only fixed the issue with the disappearing separators but also fixed the broken layout.
