When I restore an Activity from memory, I have a preview window for a couple of seconds.(Android OS just place it before loading all GUI stuff). I need to place a logo of an app in this preview window (I coded this as layout.xml) or make some splash screen (but not at the start of activity, but when it's restored).
To make situation more clear:
I have a layout with picture:
<?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"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="194dp"
android:layout_height="146dp"
android:src="#drawable/shell1" />
</RelativeLayout>
It looks like on this picture:
But, I can't use this layout for preview window. And if i use only image for preview window, I have something like that:
P.s. The second picture is not from preview window, it's just used to show the situation.
What should I do to have a proper nice look of preview window? To have this image just in the middle of screen. Thanks in advance.
This is for first Screen:
<?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"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="194dp"
android:layout_height="146dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:src="#drawable/shell1" />
</RelativeLayout>
and this is for second Screen:
<?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"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/shell1" />
</RelativeLayout>
try using-
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/shell1" />
instead of -
<ImageView
android:id="#+id/imageView1"
android:layout_width="194dp"
android:layout_height="146dp"
android:src="#drawable/shell1" />

I am new to Java and Android and I am facing this problem:
I would like to add a photo to the top/left corner of a Rectangle. However, the ImageView of my photo gets always more space and so, it creates a blank space on top that I would not like to have. Here is a screenshot:
The code of my Layout is:
<?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"
android:padding="25dp">
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:src="#drawable/profile_frame" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/imageView1"
android:layout_centerVertical="true"
android:src="#drawable/foto_facebook_juan_mejorada" />
</RelativeLayout>
Try this:
android:scaleType="fitStart"
android:adjustViewBounds="true"
It may be because of
size of the image. If the image not fit in the space given it will add blank space.
// try this way
<?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:gravity="center">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="30dp">
<ImageView
android:id="#+id/imageView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/profile_frame" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/foto_facebook_juan_mejorada" />
</FrameLayout>
</LinearLayout>
Setting a photo to an ImageView does not work as i expect. It does not fill the width completely.
This is my code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/black"
android:orientation="horizontal" >
<com.android.volley.toolbox.NetworkImageView
android:id="#+id/imageCell"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:layout_margin="5dp"
android:src="#drawable/unnamed" />
</LinearLayout>
I tried with android:layout_width="wrap_content" and still no change.
The first image is not shown completelly. The second one is in portraid mode and it's ok.
Thank you.
try setting
android:scaleType="fitXY"
to your imageView
I want to create a transparent Activity that load when we open the application on top of another Activity exactly like this.
I want that picture to be clicked and then it open the browser to open the link integrated with this image
How can I achieve this?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/transparent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:padding="2dp"
android:background="#drawable/videobackground"
/>
</RelativeLayout>
I have a little problem.
My app has a surfaceview and displays the camera preview.
Now I want a map overlay. This overlay should be displayed in a corner of the display and show the current position of the user.
Here's a preview image of what I'd like to have:
full res image
My problem is, that I don't know how to display a view/layout over another.
What I have at the moment is this as main.xml:
<?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" >
<LinearLayout
android:id="#+id/CameraPreviewLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/SurfaceViewLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<LinearLayout
android:id="#+id/MapsLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="false"
android:orientation="vertical" >
<fragment
android:id="#+id/Map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
</LinearLayout>
</RelativeLayout>
But this shows my preview layout with the + and - Button of the maps-layout.
Is it possible to get something like that? Cause I'm searching for a while now and find nothing.
Hope someone has an idea.
regards
UPDATE:
Here is my new main_activity.xml
<?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" >
<FrameLayout
android:id="#+id/SurfaceViewLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/ic_launcher" />
<fragment
android:id="#+id/Map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
class="com.google.android.gms.maps.MapFragment" />
</RelativeLayout>
I have made layout for custom dialog, it has inside two imageview. I want to show both Imageview when dialog appear. and i want to hide the main layout of my xml file I have used "#00000000" as background:color, but it is not working.
Is there any way to do the same?
Thanks.
Here is my layout. I have taken screen shot please have a look i want to hide the border which are showing in image.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent"
android:orientation="vertical" android:background="#00000000">
<LinearLayout android:id="#+id/linearLayout1"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
<ImageView android:id="#+id/img_closeimage" android:src="#drawable/product_zoom_close"
android:layout_width="wrap_content" android:layout_height="wrap_content"

</LinearLayout>
<LinearLayout android:id="#+id/linearLayout2"

android:layout_width="wrap_content" android:layout_height="wrap_content"
></ImageView>
</LinearLayout>
</LinearLayout>

Adinias comment is correct, your layout has quite some redundancy. You also say that you only want to show an imageview, but your layout contains two imageviews. If you only want to show one imageview, then your layout should look like this:
<?xml version="1.0" encoding="utf-8"?>
<ImageView android:id="#+id/img_ProductZoom" android:src="#drawable/index"
android:layout_width="wrap_content" android:layout_height="wrap_content"
/>
If you want to show two ImageViews, use this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent"
android:orientation="vertical" android:background="#00000000">
<ImageView android:id="#+id/img_closeimage" android:src="#drawable/product_zoom_close"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:clickable="true"/>
<ImageView android:id="#+id/img_ProductZoom" android:src="#drawable/index"
android:layout_width="wrap_content" android:layout_height="wrap_content"
/>
</LinearLayout>
Your current layout looks the way it does because you have specified the layout to take as much space as possible with android:layout_height="fill_parent" and android:layout_width="fill_parent". Try to use wrap_content as height and width instead.
