I need a TextView that the user can scroll horizontally with his finger. I create HorizontalScrollView and add TextView. But I can not set the width of TextView, so that it fills completely HorizontalTextView. How can this be achieved?
Thanks!
layout .xml code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageButton
android:id="#+id/btnBackspace"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="#drawable/buttonface_backspace" />
<HorizontalScrollView

</HorizontalScrollView>

I'm translating a chinese app and I want to change the bottom buttons layout from horizontal to vertical in order to fit correctly the translations. I've been playing with the orientation and gravity from the LinearLayout and CheckedTextView but the buttons stay always in horizontal.
This is the xml code,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical"
android:background="#drawable/homepage_ground" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:nav_stick="http://schemas.android.com/apk/res-auto">
<include layout="#layout/title_bar_transparent_white" />
<RelativeLayout android:layout_width="fill_parent" android:layout_height="0.0px" android:layout_weight="1.0">
<com.rockrobo.ui.RRNavigateStick android:id="#id/navigate_stick" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" />
<TextView android:id="#id/rc_starting" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="10.0dip" android:text="#string/rc_starting_up" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" />

</LinearLayout>
Could anybody help? Thanks.
Hi try changing linear layout width to match parent and orientation to vertical
I have a ListView, the item is a RelativeLayout, at left is text, and the right side is ImageView in a LinearLayout.
I expect the height of the LinearLayout**(white background)** to be fillParent but it didn't.
The effect is :
Anyone can help on this?

The main.xml is as below which contains the ListView:

android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal" >
</ProgressBar>
</LinearLayout>
enter code here
I believe this is something that the parent RelativeLayout can't handle by itself - it creates kind of a vicious circle - parent defers the height to the child (wrap_content on the RelativeLayout) and the child defers the height to the parent (match_parent on main_list_item_delete_layout).
What you can do is to anchor the top of the main_list_item_delete_layout to the parent and its bottom to another view that is guaranteed to be the bottom (the LinearLayout on the left, containing the three text views):
<RelativeLayout ...>
<LinearLayout
android:id="#+id/left_layout"
android:layout_toLeftOf="#+id/main_list_item_delete_layout"
android:layout_toStartOf="#+id/main_list_item_delete_layout"
...
>
</LinearLayout>
<LinearLayout
android:id="#+id/main_list_item_delete_layout"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:layout_alignBottom="#id/left_layout"
...>
</LinearLayout>
</RelativeLayout>
PS: in your example, in case the text on the left LinearLayout is too long, it will overflow and overlap the delete layout - hence the addition of the anchor I added to the left layout.
PS2: I know this solution is very customized to your layout. If you are set on using the RelativeLayout as a parent, you might want to try the new ConstraintLayout.
The contents of my list view get hidden behind the button as follows:
The xml file is:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="top"
>
<ListView
android:id="#android:id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false"
/>
<RelativeLayout
android:id="#+id/InnerRelativeLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
>
<Button
android:text="Send"
android:id="#+id/Button"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="addItems"
>
</Button>
<EditText
android:id="#+id/message"
android:layout_width="fill_parent"
android:layout_toLeftOf="#id/Button"
android:layout_height="wrap_content"
>
</EditText>
</RelativeLayout>
</RelativeLayout>
The TextView for each row is as follows:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content
android:layout_gravity="right"
android:gravity="right"
android:textSize="20sp"
/>
What should i do to align it properly (as in above the button)?
Also when the listView is with just one or two entries, and when the keyboard is opened to type, the whole view shifts? How do I fix that as well? Thanks in advance
Cleaned up and corected the code a bit. Perhaps this is what you were looking for. Let me know if it works. Cheers !
<?xml version="1.0" encoding="utf-8"?>

adding android:layout_above="#+id/InnerRelativeLayout" to your ListView.
RelativeLayout has child views specify their position relative to the parent view or to each other (specified by ID). So you can align two elements by right border, or make one below another, centered in the screen, centered left, and so on. By default, all child views are drawn at the top-left of the layout, so you must define the position of each view using the various layout properties available from RelativeLayout.LayoutParams.
For put your InnerRelativeLayout layout at Top add android:layout_alignParentTop="true" to your InnerRelativeLayout and remove android:layout_alignParentBottom="true"
Update: set up your Layout like below:
<?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"
android:background="#color/Beige "
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/InnerRelativeLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" >
<Button
android:id="#+id/Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:onClick="addItems"
android:text="Send" >
</Button>
<EditText
android:id="#+id/message"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/Button"
android:hint="Enter text" >
</EditText>
</RelativeLayout>
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/InnerRelativeLayout"
android:drawSelectorOnTop="false" />
</RelativeLayout>
Output:
use android:layout_above="#+id/InnerRelativeLayout" in your listview
Make the outer RelativeLayout into a LinearLayout with orientation vertical. Then, for the ListView set layout_height as 0dp and layout_weight as 1. The ListView will fill up all the remaining space in the LinearLayout without overlapping other views.
Also, stop using fill_parent, it's been deprecated and you should use match_parent instead.
I have my layout :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal"
>
<ImageView
android:id="#+id/id_new_big_list_item_image"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_centerHorizontal="true" />
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="vertical"
android:background="#drawable/round_corners_new_bottom" >
<TextView
android:id="#+id/id_new_big_list_item_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="12sp"
android:textColor="#color/new_restaurant_name"
android:paddingTop="5dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingBottom="0dp" />
</LinearLayout>
</LinearLayout>
I need to show image at the top (center horizontal) and below linearlayout with textview. Image can have different width, but i want to set the width of the linearlayout the same as image has. But if text is too long, the width becomes more. How can i do that? if text's width more than image width is, make 2 lines of text.
Is it possible??
here snap of my layout :
set ImageView's layout_width="wrap_content" and remove the 2nd LinearLayout enclosing the TextView
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal" >
<ImageView
android:id="#+id/id_new_big_list_item_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_centerHorizontal="true" />
<TextView
android:id="#+id/id_new_big_list_item_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="12sp"
android:textColor="#color/new_restaurant_name"
android:paddingTop="5dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingBottom="0dp" />
</LinearLayout>
Your Image should be wrap_contant and depends on it size. TextView will place in all parent.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal" >
<ImageView
android:id="#+id/id_new_big_list_item_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />
<TextView
android:background="#drawable/round_corners_new_bottom"
android:id="#+id/id_new_big_list_item_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="12sp"
android:textColor="#color/new_restaurant_name" />
</LinearLayout>
Good luck!
Here instead of taking a LinearLayout use a RelativeLayout.
And set the Bounds of your EditText to be Left & right aligned to the ImageView Width.So that when the length of the text is exceeding the height of the EditText is incremented in Vertical than that of Horizontal.
I'm developing an Android application.
On one activity I have a List with list items. Those list items will have a TextView (I'm using my own layout because probably I will need to add more widgets to it).
This is ListActivity 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" >
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="469dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="40dp">
</ListView>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/orderErrorMsg"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16dp" >
</TextView>
</RelativeLayout>
</LinearLayout>
And this is ListItem 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="100dp"
android:orientation="vertical">
<TextView
android:id="#+id/orderToFillName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textSize="20dp" />
</LinearLayout>
And, finally, this is the result:
Why TextView is not centered vertically?
You have "wrap_content" on the layout_height of the TextView = there is no space to center vertically on since the TextView is wrapped tightly.
Try changing the layout_height to "match_parent" or place gravity="center_vertical" attribute in the LinearLayout instead.
<TextView
android:id="#+id/orderToFillName"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:textSize="20dp" />
the answer is really simple: you have to add this to your TextView's XML:
android:gravity="center"
Currently you're not setting the text's position in the TextView but just the View's position.
Best wishes,
Tim
Try this way:
<TextView
android:id="#+id/orderToFillName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity= "center_vertical|center_horizontal"
android:textSize="20dp" />
or
android:gravity="center"
