I have around 6 images which i am using as tabs in my application.Its just images and they aren't the tabs that android provides.
So my question is that when i click on a image i want replace the image with a another image so that it can let user know that which tab is selected.
What i am did was creating different xml for this it in my layout.But its tedious to do so since I can't be creating different xml's for every image.
What i am trying to do now is using for this but not getting the result.
How is it possible to use for this ?
Its quite simple.You dont have to make different xml for each image/tab.you just have to make one xml and include this xml in every xml which needs these images..in the xml set only one image as selected and the rest unselected.Suppose for the image1 keep image1 selected and the rest unselected.by clicking image2 will redirect to activity2.In activity2 set image2 selected and the rest unselected and the same for the remaining activities.This way will be the easiest way.Trust me i have implemented this and will help you too.any sort of queries you can ask me.
i have done with 4 images but in your case there will be 6.

I'm trying to use <include> to include ImageButtons inside a android.support.v7.widget.GridLayout. The problem is, if I don't specify all the attributes explicitly on my <include> elements, they don't display properly. In other words, the include is pointless since I have to redeclare all the attributes on every <include> element.
dialpad_button.xml
<?xml version="1.0" encoding="utf-8"?>
<ImageButton
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:grid="http://schemas.android.com/apk/res-auto"
android:layout_width="0dp"
android:layout_height="0dp"
grid:layout_columnWeight="1"
grid:layout_rowWeight="1"
grid:layout_gravity="fill"
android:layout_margin="5dp"
android:scaleType="centerInside"/>
dialpad_view.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.GridLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:grid="http://schemas.android.com/apk/res-auto"
android:id="#+id/dialpad_grid_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
grid:alignmentMode="alignBounds"
grid:columnCount="2"
grid:rowCount="1">
<include
android:id="#+id/dialpad_view_btn1"
android:src="#drawable/dialpad_1"
layout="#layout/dialpad_button" />
<include
android:id="#+id/dialpad_view_btn2"
android:src="#drawable/dialpad_2"
layout="#layout/dialpad_button" />
</android.support.v7.widget.GridLayout>
If I declare all the attributes directly on the <include>s, here's what it looks like in XML:
<include
layout="#layout/dialpad_button"
android:id="#+id/dialpad_view_btn1"
android:src="#drawable/dialpad_1"
android:layout_width="0dp"
android:layout_height="0dp"
grid:layout_columnWeight="1"
grid:layout_rowWeight="1"
grid:layout_gravity="fill"
android:layout_margin="5dp"
android:scaleType="centerInside" />
As you can see in the comparison image below, the buttons now scale properly but the images are nowhere to be seen.
And if I change the <include>s to ImageButton, things work as expected.
<ImageButton
android:id="#+id/dialpad_view_btn1"
android:src="#drawable/dialpad_1"
android:layout_width="0dp"
android:layout_height="0dp"
grid:layout_columnWeight="1"
grid:layout_rowWeight="1"
grid:layout_gravity="fill"
android:layout_margin="5dp"
android:scaleType="centerInside" />
Is there a workaround to this?
Since I'm going to have 12 near-identical buttons in my dialpad, I'd really like to clean the XML up by including a "template" and only modifying the necessary attributes for each button (i.e. src and id).
EDIT
Trying to use styles, as suggested in one answer, did not work. None of the views that I applied the styles to get displayed. What's even more strange, even if I just apply the style to one of the views in the GridLayout, only the last view gets displayed (I've shortened down the sample code here to only two views for readability, in reality I have twelve).
Here's the style I tried using:
<?xml version="1.0" encoding="utf-8"?>
<resources
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:grid="http://schemas.android.com/apk/res-auto" >
<style name="dialPadButtonStyle">
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">0dp</item>
<item name="grid:layout_columnWeight">1</item>
<item name="grid:layout_rowWeight">1</item>
<item name="grid:layout_gravity">fill</item>
<item name="android:layout_margin">5dp</item>
<item name="android:scaleType">centerInside</item>
<item name="android:background">#android:color/transparent</item>
</style>
</resources>
Maybe you can use a style to declare the common attributes and then set it for every button.
<style name="dialPadButtonStyle">
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">0dp</item>
<item name="android:layout_columnWeight">1</item>
<item name="android:layout_rowWeight">1</item>
<item name="android:layout_margin">5dp</item>
<item name="android:src">#android:drawable/ic_menu_camera</item>
</style>
I also added: columnCount to 3 and rowCount to 4 for GridLayout and added 12 ImageButtons with that style. The final result is this:
Is it possible to create a custom rating bar like this?
If yes, can you give me an example on how to do it?
Thanks in advance!
Great tutorial here.
I will copy important parts in this answer in case the link will be invalid.
First you should create a style which extends the original RatingBar
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="foodRatingBar" parent="#android:style/Widget.RatingBar">
<item name="android:progressDrawable">#drawable/food_ratingbar_full</item>
<item name="android:minHeight">48dip</item>
<item name="android:maxHeight">48dip</item>
</style>
</resources>
Then you need to provide 3 drawables, why? Because you should fill the 3 cases: empty, 50% and full.
This file will be food_ratingbar_full.xml
> Here’s an example of a filled rating (cookie):
<!-- This is the rating bar drawable that is used to
show a filled cookie. -->
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:state_window_focused="true"
android:drawable="#drawable/cookie" />
<item android:state_focused="true"
android:state_window_focused="true"
android:drawable="#drawable/cookie" />
<item android:state_selected="true"
android:state_window_focused="true"
android:drawable="#drawable/cookie" />
<item android:drawable="#drawable/cookie" />
</selector>
I just use one image for all states (and it actually looks decent),
but as you can see from the selector, there are four different states
possible (#drawable/cookie is finally an actuall cookie png image).
And the cool thing here is that RatingBar component will automatically
fill in part of the cookie when needed based only on “full” and
“empty” images (if you support half ratings, as in my example image).
Then to use your style you should just add style attribute in RatingBar XML.
style="#style/foodRatingBar
The point is: you should create a custom style if you want.
Then you could use setRotation to rotate it.
Sets the degrees that the view is rotated around the pivot point. Increasing values result in clockwise rotation.
EDIT: This is not an appropriate answer, as OP wanted to customize RatingBar. But it is still a solution.
It is possible. You just have to put each one of the five image resources in your project and then, make a layout like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="60dp"
android:layout_height="match_parent"
android:background="#android:color/black"
android:gravity="left"
android:orientation="vertical"
android:weightSum="5" >
<ImageView
android:id="#+id/oneStar"
android:layout_width="50dp"
android:layout_height="0dp"
android:layout_weight="1"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/twoStars"
android:layout_width="50dp"
android:layout_height="0dp"
android:layout_weight="1"
android:src="#drawable/ic_launcher"
android:visibility="visible" />
<ImageView
android:id="#+id/threeStars"
android:layout_width="50dp"
android:layout_height="0dp"
android:layout_weight="1"
android:src="#drawable/ic_launcher"
android:visibility="visible" />
<ImageView
android:id="#+id/fourStars"
android:layout_width="50dp"
android:layout_height="0dp"
android:layout_weight="1"
android:src="#drawable/ic_launcher"
android:visibility="visible" />
<ImageView
android:id="#+id/fiveStars"
android:layout_width="50dp"
android:layout_height="0dp"
android:layout_weight="1"
android:src="#drawable/ic_launcher"
android:visibility="visible" />
Put your resources as source of your ImageViews. That should be a start for you :D
I'm having trouble with the layout of my Android app.
The graphical preview editor shows me an image like (and this is how I want it to look like):
I am using a table layout that looks like this:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:shrinkColumns="*"
android:stretchColumns="*" >
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ffffff"
android:padding="5dp" >
<TextView
style="#style/leftColumn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Branche" />
<TextView
android:id="#+id/textViewBranche"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/rightColumn"
android:text="Branche"
/>
</TableRow>
</TableLayout>
styles.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<!-- ... -->
<style name="leftColumn">
<item name="android:background">#2B60DE</item>
<item name="android:textColor">#ffffff</item>
</style>
<style name="rightColumn">
<item name="android:background">#C0C0C0</item>
<item name="android:textColor">#ffffff</item>
</style>
</resources>
If I run my app it looks like this:
As you can see only one text view is displayed. I would like the table layout to have 2 columns (just like in the preview). The first one (blue) indicating what I am displaying and the second (grey) the information provided by my adapter. However I only see the provided information of my adapter (in this case "sonstige (others)". So basically I only see the right column.
I have no idea why I can't see the content of the first text view (respectively the first row).
I played around with some properties like layout_width and layout_height but it doesn't change.
I'm running this app on my S3.
Any help would greatly be appreciated.
Cheers
I'm developing an Android application and I use this to customize RadioButtons:
<!-- Radio button style -->
<style name="RadioButton" parent="#android:style/Widget.CompoundButton.RadioButton">
<item name="android:button">#drawable/checkbox_unchecked</item>
</style>
But the image #drawable/checkbox_unchecked is very big.
Do you know how can I make it smaller?
I know you can achieve what you want by reducing the size of your image. But I would recommend using the following code. This will help you set images for both the unselected and selected modes.
This is how you can achieve it, in a few steps:
-Create Image Drawables for their two states (checked/unchecked).
-Create selector for this two drawables. The sample content should be something like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="#drawable/unchecked" />
<item android:state_checked="false" android:drawable="#drawable/checked" />
</selector>
-Add this selector as a android:button attribute to RadioButton
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/background">
<RadioButton
android:id="#+id/radioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="#drawable/checkbox_selector"
android:text="Custom RadioButton" />
</LinearLayout>
I am using a selector working fine in all activities as you can see its XML below.
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:drawable="#drawable/active_date_horizontal_5_pressed" /> <!-- pressed -->
<item
android:state_focused="true"
android:drawable="#drawable/active_date_horizontal_5_pressed" /> <!-- focused -->
<item
android:drawable="#drawable/active_date_horizontal_5" /> <!-- default -->
Except one activity, it does not work ridiculously. You can see three screenshots below which the selector works fine in the first two screenshots, and does not work in the last screen shot.
1)
2)
3)
These are customized GridViews which filled with customized BaseAdapter. Cells in the GridViews have an Xml Layout which its background is the selector. Any ideas?
It seems I solved my own problem.
You can see the Xml Layout which I am applied the selector 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="60dp"
android:orientation="vertical"
android:background="#drawable/calendar_cell_selector" >
<TextView
android:id="#+id/txtWeeklyEventName"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ImageView
android:id="#+id/imgCornerWeekly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/txtWeeklyEventName"
android:layout_alignRight="#+id/txtWeeklyEventName"
android:src="#drawable/corner_orange"
android:visibility="visible" />
</RelativeLayout>
You can see the background of the RelativeLayout is the selector, but the TextView fills upon the whole layout so Android cannot handle the selector.
Thus, I removed the background from the RelativeLayout and set it for the TextView, it totally works.
Thanks to me!
