problem in displaying text view above a map - android

I have to display three text views above a map in one of my activities and I have the following xml...but I don't know why I see no text view only my map.
Here is my xml file:
<?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:id="#+id/first"
android:background="#0000ff">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:id="#+id/bar"
android:layout_below="#id/first"
android:layout_height="wrap_content"
>
<TextView
android:id="#+id/prod1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dip"
android:textSize="12px"
android:text="Sursa"
/>
<TextView android:id="#+id/prod2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:paddingLeft="83dip"
android:textSize="12px"
android:text="destinatie"
/>
<TextView android:id="#+id/prod3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right"
android:paddingLeft="85dip"
android:textSize="12px"
android:text="data"
/>
</LinearLayout>
<com.google.android.maps.MapView
android:id="#+id/mapview1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="0egkyrbiooKAfYyj43YB6wW1cmlG-TiIILXjpBg"
/>
</RelativeLayout>

That's because you set the height of your MapView to 'fill_parent'. Set to some fixed height just for debugging purposes and you should see your text views - they may not appear above the map, as you want, because you've set the LinearLayout to go below the RelativeLayout and it contains the MapView.
Remove the code from the LinearLayout:
android:layout_below="#id/first"
and add this to the MapView element:
android:layout_below="#id/bar"

You can also use MERGE tags as the root for your layout, which allows for multiple layouts to be layered over each other.

Android Layout- Part of TextView goes off edge of screen

I have a LinearLayout with a custom button and then another LinearLayout with two TextViews, which is always partly cut off on the edge of the screen. I have tried tons of different combinations of fill_parents, match_parents, and wrap_contents, as well as trying to add layout_weights, but nothing solved it, nor did any answer to any similar questions on this site. Here is my XML code, thanks for any help!
<?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="horizontal" >
<com.goldtrimdevelopment.sites.google.com.interesthub.SquareButton
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1" >
<Button
android:id="#+id/list_article_like_button"
style="?android:attr/borderlessButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:background="#drawable/custom_like_button"
android:contentDescription="#string/like_button"
android:padding="5dip" />
</com.goldtrimdevelopment.sites.google.com.interesthub.SquareButton>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/article_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="3"
android:textSize="16sp" />
<TextView
android:id="#+id/article_link"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="3"
android:singleLine="true"
android:textSize="12sp" />
</LinearLayout>
</LinearLayout>
I figured from your xml file that you want the layout to be a custom button and to its right 2 textviews which are vertically linear, while the buttons and the textviews are horizontall linear. Try the following values in your layout. I think it must solve the issue.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" or "wrap content"
android:orientation="horizontal" >
and the next linear layout as
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
and for both textviews set
android:layout_width="150dp"
try it and let me know.

ListView hidden behind button

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"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/InnerRelativeLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_width="wrap_content"
android:layout_height="40dp"

android:layout_above="#id/InnerRelativeLayout" />
</RelativeLayout>
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.

Android: Layout List header

I have a header for a list that contains two image buttons. I want one of those image buttons to be on the left, and the other to be on the right. This is what my xml file looks like right now but it does not work, it just puts the two image buttons on the left together. I have also tried without the additional LinearLayouts but no luck.
<?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="horizontal"
android:gravity="fill_horizontal"
android:background="#drawable/list_header_background">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:gravity="left"
android:background="#drawable/list_header_background">
<ImageButton
android:id="#+id/refreshBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="4dp"
android:src="#drawable/ic_refresh"
android:background="#drawable/list_header_background"
/>
</LinearLayout>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:gravity="right"
android:background="#drawable/list_header_background">
<ImageButton
android:id="#+id/battleBtn"
android:layout_width="wrap_content"

android:background="#drawable/list_header_background"
/>
</LinearLayout>
</LinearLayout>
As kabuko wrote, the RelativeLayout width is equal to the parent width. When we have a child view inside that RelativeLayout, we can use the android:layout_alignParentXXXXXX="true" parameter in order to align it (the child) accordingly to the parent.
<?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:orientation="horizontal"
android:background="#drawable/list_header_background">
<ImageButton
android:id="#+id/refreshBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="4dp"
android:src="#drawable/ic_refresh"
android:layout_alignParentLeft="true"
android:background="#drawable/list_header_background"
/>
<ImageButton
android:id="#+id/battleBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="4dp"
android:src="#drawable/ic_battle"
android:layout_alignParentRight="true"
android:background="#drawable/list_header_background"
/>
</RelativeLayout>
You probably want to use a RelativeLayout with layout_alignParentLeft and layout_alignParentRight on the buttons.

Why my text is always located on the top of screen not center?

I have a simple layout like below (which only shows a text "TEST"):
<?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"
android:background="#ffffff"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="TEST"
android:textColor="#0099cc"
/>
</LinearLayout>
</LinearLayout>
I suppose with this layout, my text "TEST" should be located in the middle of the screen. But the text "TEST" is located on the top of the screen. Why?
I used layout_gravity and gravity with value center, why my "TEST" text located on the top?
use android:gravity="center" in your main layout
just try it.
<?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"
android:background="#ffffff"
android:gravity="center"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="TEST"
android:textColor="#0099cc"
/>
</LinearLayout>
</LinearLayout>
Hi leem android:gravity consult with the content of specific view that means your android:gravity="middle" place the text middle of text view not a middle of screen. your layout_gravity define the where should your view is going to be place? mean you have to set android:layout_gravity="center_vertical|center_horizontal" of textview to view your text middle of screen
Very simple.. In the first linear layout section of your xml file. Just add android:gravity="center" and it will work..

Why can't get IgnoreGravity within RelativeLayout to work?

I have two buttons. I want one to be aligned at the top center of the application. I want to get the other button to ignore the gravity settings and go where I tell it. How do I do this?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relative_layout"
android:layout_width="fill_parent"
android:gravity="center_horizontal"
android:layout_height="fill_parent" >
<Button
android:id="#+id/the_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Centered Button"
android:layout_alignTop="#id/relative_layout" />
<Button
android:id="#+id/the_button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Random Button"
android:ignoreGravity="#id/relative_layout" />
</RelativeLayout>
Do not use gravity attribute of RelativeLayout, elements within RelativeLayout can be positioned with additional attributes. Try this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relative_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="#+id/the_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Centered Button"
android:layout_centerHorizontal="true" />
<Button
android:id="#+id/the_button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Random Button"/>
</RelativeLayout>
See RelativeLayout tutorial and RelativeLayout.LayoutParams docs for more information about usage of RelativeLayout.
