In my application, I'm trying to set the splash theme with a drawable background. It works correctly if I use a small image, but when the image is bigger then the screen size, it doesn't work anymore.
The image is correctly scaled horizzontally, but the height isn't, as follows:
I tried every scaletype and gravity, what else can I do?
this is my Theme:
<style name="SplashTheme" parent="AppTheme">
<item name="android:windowBackground">#drawable/background_splash</item>
</style>
This is my background_splash.xml
<item android:drawable="#android:color/white" />
<item
android:left="50dp"
android:right="50dp"
>
<bitmap android:src="#drawable/logo_splash"
android:gravity="center|clip_horizontal"
android:scaleType="centerInside"
/>
</item>
and this is my manifest (relevant code):
<activity
android:name=".activities.SplashScreenActivity"
android:configChanges="orientation|screenSize"
android:theme="#style/SplashTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Any idea?
You can use a layer-list like this in your background_splash.xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="#android:color/white"
android:gravity="fill" />
<item
android:drawable="#drawable/logo_splash"
android:gravity="center" />
</layer-list>
This will center your image on the screen and the left space will be filled by the white background color.
Maybe you have to add the image in different sizes like you can read here:
https://developer.android.com/training/multiscreen/screendensities#TaskProvideAltBmp
If you do that you can access the image with the same name. It will look like this your project structure:
If you want to remove the action and status bar in your splash screen, you can add the following line to your SplashTheme:
<item name="android:windowFullscreen">true</item>

I have a splash screen activity with the following theme:
<style name="AppTheme.Launcher" parent="Theme.AppCompat.NoActionBar">
<item name="android:background">#drawable/splash_theme</item>
</style>
Here is a part of my manifest:
<activity
android:name=".activities.SplashActivity"
android:theme="#style/AppTheme.Launcher">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
And here is my drawable:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:opacity="opaque">
<item android:drawable="#color/colorPrimaryDarkBackground" />
<item>
<bitmap
android:gravity="center"
android:src="#drawable/shelpwelt_theme" />
</item>
</layer-list>
At some builds all works perfectly but sometimes the splash screen is completely distorted and blurred but just at the first 2-3 seconds. Then when my splash screen activity reaches onCreate the theme looks perfectly fine.
Here is the problem:
You are using a gif file for this case. And after the given time you said, 2-3 sec it wraps the screen size, so the image gets bigger. That's why it get's blurred on the screen.
Add bottom,left,right,top size to your item.
Change your drawble file to this :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:opacity="opaque">
<item android:drawable="#color/colorPrimaryDarkBackground" />
<item
android:bottom="24dp"
android:left="24dp"
android:right="24dp"
android:top="24dp"
>
<bitmap
android:gravity="center"
android:src="#drawable/shelpwelt_theme" />
</item>
</layer-list>
It might be a scaling issue, try to change splash's layout, instead of designing the entire image and set it as a background, design your layout to have two images one for the gray rectangle and the other for the video icon
I want to display the bg image as the splash screen. So how can I set the image to device screen width and device screen height. Can I do it from the xml file below (this xml file is inside drawable folder) . I tried to put fill_parent or match_parent in the width but it gives error. Is there any way to do it?
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="#color/white"/>
<item
android:drawable="#mipmap/bg"
android:gravity="center"
android:width="300dp"
android:height="600dp"/>
</layer-list>
Set the image to the ImageView in the splash screen and set the scaleType attribute of the ImageView as "fixXY".
Replace android:drawable="#color/white with background drawable.
<!-- in your_splash_screen.xml -->
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/your_background" />
</layer-list>
<!--in values.xml -->
<style name="AppTheme.SplashScreen" parent="AppTheme">
<item name="android:windowFullscreen">true</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowBackground">#drawable/your_splash_screen</item>
</style>
<!--in AndroidManifest.xml -->
<activity
android:name=".SplashActivity"
android:theme="#style/AppTheme.SplashScreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I'm trying to add splash-screen to my Android app.
I've been following instructions from here. It's the standard way as I get it, and it seems logical.
So it's really simple right? Create drawable resource, use it in a theme as windowBackground, use the theme? Well it doesn't work for me...
manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<activity android:name="euroicc.sicc.ui.MainActivity"
android:theme="#style/AppTheme.Splashscreen">
<intent-filter>

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

I've tried other codes from other sites, but nothing seems to work.
Only white background is displayed for less then a second (approximately), and then the app starts running. I'm setting the theme AppTheme in onCreate method of main activity so it uses it's default theme always except on start.
I'm also overriding onPause and onResume, but I call their supers, so that shouldn't be a problem.
I'm testing on v7.0.0, but that shouldn't be a problem also?
I have more styles but I removed them from the example code, because they are used for dialogs and elements inside xml files, not for activities.
So what is the problem and how do I solve it? When I first read about splashscreens I thought setting windowBackground would've been enough
You don't set your background in styles.xml, rather inside your splashcreen layout xml file. Here is my layout example:
<?xml version="1.0" encoding="utf-8"?>
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="ContentDescription"
android:background="#drawable/green" ==============================> HERE!
tools:context=".activity_splash_screen">
<ImageView
android:id="#+id/logo"
android:layout_width="#dimen/_150sdp"
android:layout_height="#dimen/_150sdp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="#dimen/_100sdp"
android:src="#drawable/white_logo"
/>
<ImageView
android:id="#+id/title"
android:layout_width="#dimen/_240sdp"
android:layout_height="#dimen/_150sdp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="#dimen/_100sdp"
android:src="#drawable/title"
/>

I've had this problem. I created the splash screen as a layer-list drawable, and in the theme as windowBackground as it is recommended everywhere, yet it wouldn't work on some devices (like my and my friend's Motorolas, a few other phones) - a black screen would be shown. For me the solution was to wrap my splash activity code in a Handler's postDelayed runnable with some small delay:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
Handler(Looper.getMainLooper()).postDelayed( { //this is a trick so the splash screen - in window bg theme - is displayed on all devices, instead of black screen. E.g. moto g6
val startMainActivityIntent = ...
startActivity(startMainActivityIntent)
finish()
}, 100)
}
I am not particularly fond of delaying UI, if I knew a better way that worked, I would not do this. But it’s better than black screen.
What I would like to know is, if there's a way to change any click color at the whole Activity.
I've set up a the maniest the next Activity -
<activity android:name="com.example.test.MainActivity"
android:theme="#style/Theme.Base.AppCompat.Light.DarkActionBar"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" >
</action>
<category android:name="android.intent.category.NORMAL" >
</category>
</intent-filter>
</activity>
As you can see I am using the next theme for the Activity -
android:theme="#style/Theme.Base.AppCompat.Light.DarkActionBar"
This make any click color to be blue- meaning when a button or anything else is being pressed it turning into blue when it's clicked.
Now what i would like to know is there any way to change the blue color into a diffrent color, and now by changing the background for each view item that i'm gonna use.
Thanks for any kind of help
file name: /res/drawable/button_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:drawable="#color/color1"/>
<item android:state_focused="true" android:drawable="#color/color1"/>
<item android:state_pressed="true" android:drawable="#color/color1"/>
<item android:drawable="#color/color1"/>
Take this file into your Button Style like this:
create new style in your resource value folder like below example and change your application attribute android:theme="#style/CustomActionBarTheme"
<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme" parent="#style/Theme.Base.AppCompat.Light.DarkActionBar>
<item name="android:buttonStyle">#style/srp_button</item>
</style>
<style name="srp_button" parent="#android:style/Widget.Button">
<itemname="android:background">#drawable/button_color</item> <!-- Here isspecifiedtext color -->
</style>
im trying to play a video or show a picture on the phone while still being able to control the phone.
the only thing ive managed to do so far is to start a new transparent activity.
that enables me to show whatever i would like. but i cannot control the phone behind the pic/video.
this is my code:
<activity
android:name=".VideoPopActivity"
android:label="#string/app_name"
android:theme="#style/Theme.Transparent" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
and in the styles.xml:
<style name="Theme.Transparent" parent="android:Theme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:background">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
<item name="android:backgroundDimEnabled">false</item>
<item name="android:windowFrame">#null</item>
open to new suggestion aside from this "trick".....
No, you cannot control an inactive Activity, specifically one that is beneath the active one.
What you'll want to do is create a RelativeLayout that contains your transparent picture as well as the main layout. This will layer them on top of each other. Make sure both are match_parent for both width and height.
<RelativeLayout
... >
<LinearLayout
... >
<!-- This is your main layout -->
</LinearLayout>
<ImageView
android:visibility="gone"
... /> <!-- Your picture, invisible by default -->
</RelativeLayout>
Or, instead of an ImageView, make another layout, in which you can place your video/image content.
This is way to to make activity transparent, however to get more pleasing view, you should make your activity not apaoque, not transparent, as it will give a mirror like or water like view..
you could use,
You should create opaqueStyle.xml in the drawable folder and set your main layout's background as the opaqueStyle.xml..
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke android:width="1dp" android:color="#FFFFFFFF" />
<solid android:color="#30646464" />
<corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp" android:topRightRadius="7dp"/>
</shape>
Here in <solid android:color="#30646464" /> this line, "#30646464", 30 is for opacity, you can increase or decrease its opacity and else six digits are the color, you can adjust it for urself..
