When I run my android application in Android version >=4 I got this out put(I didn't tested in android version 3):
When run the same application in android version 2.3 I got a bit different output:
You can see in second screenshot the image for about button is not visible. But when I try run the same application several times on 2.3 some times I got about image visible.Here is my code :
<?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" >
<include layout="#layout/actionbar_with_right_button" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"

android:drawableTop="#drawable/help_button"
android:gravity="center"
android:onClick="showFaq"
android:padding="#dimen/settings_text_view_padding"
android:text="#string/help" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:drawablePadding="#dimen/settings_text_view_drawable_padding"
android:drawableTop="#drawable/about_button"
android:gravity="center"
android:onClick="showAbout"
android:padding="#dimen/settings_text_view_padding"
android:text="#string/about" />
</LinearLayout>
</ScrollView>
I didn't understand why this is happening.
Can anyone help me to solve this issue.
Edit :
One more important thing I forgot to mention when I changed android:drawableTop="#drawable/about_button" to android:drawableTop="#drawable/help_button" of about TextView. It worked perfectly. So it can be an issue of my about_button image. So I recreated the about image again and put in all drawable folder. Even after that also I didn't get any +ve result. This issue only in 2.3 or less.
Thanks
May this help you:
Seems like this is a bug with android, where sometimes the first image in the drawable folder doesn't get displayed.....
I had a similar bug - a particular drawable was not being displayed, no matter in what ImageView. So I Added a dummy image called aaaa.png to the drawable folder and problem was solved....

I have browsed through a few places but can't find anything "exact" to solve my issue. I set code in Android Studio and the display showed my top text as orange and the bottom text as blue...which is what I intended. When I tried running it on my phone, the text color did not show as it does in Android Studio. (Just is gray text on my phone)
This is a simple bit of code as I'm currently learning from Udacity and a couple other places. Any ideas why code would show as working on Android Studio but wouldn't work on the phone? (especially when dealing with something as simple as text color?)
The code is as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.saoiray.happybirthday.MainActivity">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:text="I'm awesome! Birth of a developer (^_^)"
android:textColor="#FF5722"
android:textSize="32sp" />
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Oh yeah, Stephen is awesome!"
android:textColor="#3F51B5"
android:textSize="32sp" />
<ImageView
android:id="#+id/androidparty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:src="#drawable/androidparty"
tools:ignore="ContentDescription" />
</RelativeLayout>
I had the same problem, and i disabled the "High contrast fonts" from the Settings-> Display -> Visibility enhancements , of the phone and now the textColor appears like in Virtual Device
I am a newbie to android app development, i am using the ADT with eclipse.
I wrapped all the view components in a scrollbar but when i use the emulator preview i cannot see the scrollbar. The target is a 7inch WSVGA (Tablet).
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/imageDate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/test_image_date"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ImageView
android:id="#+id/Clouds"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/test_image"
/>
<TextView
android:id="#+id/imageDescription"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/test_image_description"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
</ScrollView>
No errors have been generated.

The scrollview will only be visible if you have enough content that would not fit on the entire screen. Seeing your xml it is possible that you don't have that much of content in the layout
So ran this activity on a Samsung T3 8 inch tablet and the scroll worked fine, couldn't seem to get it on the emulator with a similar simulated device.
My app is showing the 9patch black marks. Why could it be?
That's my picture:
You can see the small black dots. The file name is "filename.9.png".
I am using the 9patch program that comes with android sdk.
That's my code:
<ScrollView
android:id="#+id/left_scroll"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/pic_coupon_calender"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#drawable/pic_coupon_news" />
</RelativeLayout>
</ScrollView>
The background is "pic_coupons_news.9.png".
What could be the reasons for such a thing?
Thanks!
It happened with me once too.
Just clean your project and rebuild. This should resolve the defect.
I'd like to use a 1x1 size Nine-patch image from Android drawable resources.
When I'm trying to display it with <ImageView> in my layout xml file, this one is never showing up on the Android emulator device. Here's the xml code below:
<?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:padding="10px"
>
<RelativeLayout
android:gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:id="#+id/text_label"
android:text="#string/text"
android:textSize="10pt"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<CheckBox android:id="#+id/my_checkBox"
android:layout_alignBaseline="#id/text_label"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
<ImageView android:paddingTop="10px"
android:paddingBottom="10px"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:src="#android:drawable/divider_horizontal_bright" />
</LinearLayout>
I tried another one with the same size and I have the same problem it's still blank.
My research on Google was irrelevant. Hope you can find what am I doing wrong here.
Thanks in advance for your help.

What version of the SDK are you writing for?
Take a peek at the divider_horizontal_bright.png files in the different versions :)
It's 99% transparent in 8, but like 50% transparent light grey in 4.
Or, Perhaps you meant divider_horizontal_bright_opaque?
This works for me:
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="#android:drawable/divider_horizontal_dark"
android:scaleType="fitXY"
/>
I have a crash (Application Stopped Unexpectedly) problem with this main.xml is a "HelloWorld" type project (while testing and learning features I need for my app) :
I isolated the ImageButton as an issue, but I can't isolate any of the parameters...
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageButton android:id="#+id/picture"
android:layout_width="240dip"
android:layout_height="180dip"
android:layout_gravity="center_horizontal"
android:src="#drawable/icon"
android:adjustViewBounds="true"
android:cropToPadding="true"
android:clickable="true"
android:scaleType="fitCenter" />
</LinearLayout>
icon.png exists in my resources...
I can see the preview in the Layout tab, even though the image is not centered on the button, but I read that it was normal.
The code below works fine (as a regular Button). I can also do the same as an ImageView.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button android:id="#+id/picture"
android:layout_width="240dip"
android:layout_height="180dip"
android:layout_gravity="center_horizontal" />
</LinearLayout>
I use Eclipse and the AVD, and all my learning is done on 2.1 (SDK level 7).
I can't test the app on an actual device yet as I don't have it yet.
Thanks in advance !
Oh bother !!
It seems that it was a java error in my MyApp.java, when I was trying to declare the event for the button. Case closed. Sorry.
