I've got an ImageView centered inside a RelativeLayout using android:layout_centerHorizontal="true" and android:layout_centerVertical="true".
Can I animate (move) it to let's say the bottom right corner, using XML and/or code? I'd like to specify the duration of the animation as well as possibly the curve.
Before:
<ImageView android:id="#+id/imageview01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:src="#drawable/imagefile" />
After:
<ImageView
android:id="#+id/imageview01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:src="#drawable/imagefile" />
check Android Translate Animation
Piggybacking on Mosh, this looks to be a helpful earlier answer:

I want to achieve something of the format as shown in the image. The blue part is background, the image of the guy and girl is a ImageButton. The original images for these are 88x128 (trainer000, trainer001). I want to rescale the ImageButton such that the image covers the entire height and the width is adjusted accordingly. Now I found 2-3 ways to do so but they make use of a separate class to calculate width. I want to know if there is a way to do it purely in the xml file itself.
What I used:
`
<ImageButton
android:id="#+id/maleimage"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:adjustViewBounds="true"
android:scaleType="fitStart"
android:layout_alignParentLeft="true"
android:src="#drawable/trainer000" />
<ImageButton
android:id="#+id/femaleimage"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:adjustViewBounds="true"
android:scaleType="fitStart"
android:layout_alignParentLeft="true"
android:src="#drawable/trainer001" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:textColor="#000000"
android:text="Are you a boy or a girl?"
android:textAppearance="?android:attr/textAppearanceMedium" />

EDIT: Found the solution. I just used Studio's Layout editor.
I want to put png image over button i tried android:background but the png takes all the button what i want exactly is to use the logo png over button like this
the info logo is my png and "about" comes from the button text
u can use this:
android:drawableTop="#drawable/SomeIcon"
so then you get this:
<Button
android:id="#+id/damage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="about"
android:drawableTop="#android:drawable/ic_menu_info_details"/>
it works for me :)
You can use a FrameLayout. In a FrameLayout, the z-index is defined by the order in which the items are added, for example
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/my_drawable"
android:scaleType="fitCenter"/>
</FrameLayout>
In this instance, the ImageView would be drawn on top of the Button, along the bottom center of the Button.
You can check this thread
Basically, you can use:
<ImageButton
android:id="#+id/ImageButton01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/album_icon"
android:background="#drawable/round_button" />
As the thread says.
Take a RelativeLayout, place ImageView inside it. Now set onClickListener on RelativeLayout.
By this way you can create more complex buttons.
<RelativeLayout android:id="#+id/your_btn_id"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />
</RelativeLayout>
you can use
android:drawableTop
to put drawable at top of Button and use appropriate padding to make it position well.
<Buttton
android:layout_width="99dp"
android:layout_height="99dp"
android:background = "#drawable/bg" />
bg is your custom image.
I have a FrameLayout and I want to have as much small as possible. But that layout gives me some invisible margins from top and bottom. That's how it looks:
And should look:
My FrameLayout looks like that:
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto">
<ImageView
android:id="#+id/ivPress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center"
android:background="#drawable/custom" />
<com.devadvance.circularseekbar.CircularSeekBar
android:id="#+id/circularSeekBar1"
app:circle_x_radius="147"
app:circle_y_radius="147"
app:use_custom_radii="true"
app:max="100"
app:pointer_alpha_ontouch="100"
app:pointer_color="#ffffff"
app:pointer_halo_color="#ffffff"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/tvResult"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:layout_gravity="center"
android:text="Tap!"
android:textColor="#FFFFFF"
android:textSize="50dp" />
</FrameLayout>
Let me confirm my understanding is correct.
Blue gradation image is set to ImageView(ivPress).
CircularSeekBar class decides where draws circle.
If my understanding is true, FrameLayout has no magins. ImageView(ivPress) can be shown without margins.
So, the issue you should solve is that there are margins in top and bottom of circle, right? I don't know how you implement CircularSeekBar class but some problem is in it.
i am writing an application to control a robot
for controlling i need ( up, down , right, left ) keys
i used eclipse designer to create it but maybe it is not possible
i want to create something like this :
how can i create buttons like this in center of screen ?
is there a better way to create arrow keys on android ?
Here you go :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<View
android:id="#+id/view1"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/view1"
android:layout_centerHorizontal="true"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/view1"
android:layout_centerHorizontal="true"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toRightOf="#+id/view1"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/view1"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
Of course, you can replace ImageView with anything else like an ImageButton.
Be sure, if you change the name of the first view, tu update the name in the 4 ImageView.
And be aware that the corners of each image are overlapping each other.
I suggest using ImageButtons and setting the background for each to a State List Drawable xml file. This will change the image between states(focused, pressed, etc).
The tricky part would be positioning each so that they orient themselves in this sort of "box" you have above.
Just create some PNGs of each button in their positions. Up button points up, left points left etc. Then use RelativeLayout to position them with respect to each other. You can also use Buttons as well
So I'm working on making a design for my app and I need to put a imagebutton directly below an imageview. But since my imageview has a border around it with a drop shadow I need to hide (shift up) maybe 10 pixels of my imagebutton behind my imageview. Here is a quick drawing of what I want.
I hope that makes sense. I've been messing around with all kinds of different arrangements but I cant get what I want. Any help would be greatly appreciated.
First of all use a RelativeLayout. Add first the ImageButton and then the ImageView, in this way the ImageView will be on top of your ImageButton. Then you should set on your ImageButton the following :
<ImageButton
....
android:layout_below="#id/ImageViewId"
android:layout_marginTop="-10px" />
Use relative layout as said. Refer
http://developer.android.com/reference/android/widget/RelativeLayout.LayoutParams.html
for more positions and easy design.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/Imageview"
android:layout_marginTop="-16dp" />
<ImageView
android:id="#+id/Imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="46dp"
android:adjustViewBounds="true"
android:contentDescription="#string/description_logo"
android:src="#drawable/imagename" />
</RelativeLayout>
