I want to design a spinner as displayed in the image below:
I am not getting the arrow symbol pointing downside in spinner. How can I do this?
If I make a button design like shown above then I have to write extra code to get similar functionality as for a spinner, as Spinner doesn't have android:drawableRight="#drawable/arraodown", but in the button we have this method.
Do not mess around with right/left/... drawables.
Just set one 9-patch drawable as background that limits the inner content.
<Spinner
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/you_spinner_drawable" />
Regarding the 9-patch drawable have a look at the android resources or at this example picture taken from this blog post (which shows in little more detail on how to make a custom spinner):
For information about 9-patch drawables see the android documentation:
http://developer.android.com/guide/topics/graphics/2d-graphics.html#nine-patch
http://developer.android.com/tools/help/draw9patch.html
Of course you can also specify a State list xml file as drawable, eg.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When disabled -->
<item android:state_enabled="false"
android:drawable="#drawable/your_disabled_spinner_drawable" />
<!-- When selected -->
<item android:state_pressed="true"
android:drawable="#drawable/your_selected_spinner_drawable" />
<!-- When not selected-->
<item
android:drawable="#drawable/your_default_spinner_drawable" />
</selector>
http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList
<Spinner
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/you_spinner_drawable" />
**You can use the below mentioned Drawable to set as background for this spinner**.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When disabled -->
<item android:state_enabled="false"
android:drawable="#drawable/your_disabled_spinner_drawable" />
<!-- When selected -->
<item android:state_pressed="true"
android:drawable="#drawable/your_selected_spinner_drawable" />
<!-- When not selected-->
<item
android:drawable="#drawable/your_default_spinner_drawable" />
</selector>
You will have to create a custom layout for the spinner. I think the following XML might give you an idea.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="3dip">
<TextView
android:id="#+id/number"
android:padding="3dip"
android:layout_marginTop="2dip"
android:layout_marginLeft="5dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
Just use GIMP as your image editor and change background color and border with a color you like.
For example, I did this image by editing an existing one I found on the Internet: http://sdrv.ms/1lRkTbG

When I run this code, the password visibility toggle icon is inverted. It shows 'open eye' icon if password is hidden and vice versa.
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/id_txtInpLayout_pass"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:passwordToggleEnabled="true"
android:layout_marginTop="10dp"
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/id_txtInpEditTxt_pass"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="#string/hint_pass"
android:inputType="textPassword"
android:ems="14"/>
</com.google.android.material.textfield.TextInputLayout>
I did not write any code in MainActivity.java.
app:passwordToggleEnabled has become deprecated. For a good use you should now use the endIconMode in your TextInputLayout like this:
app:endIconMode="password_toggle"
Then in your TextInputEditText use:
android:inputType="textPassword"
And that's it. Here is the full example XML code:
<com.google.android.material.textfield.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:id="#+id/editTextLayoutPassword"
android:layout_width="300dp"
android:layout_height="match_parent"
android:hint="Password"
app:endIconMode="password_toggle">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/editTextPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textPassword"
android:maxLength="20" />
</com.google.android.material.textfield.TextInputLayout>
EDIT: It seems it may still be inverted, so here is a final solution.
Create a new Drawable Resource File, call it custom_eye and insert this code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/ic_opened_eye"
android:state_checked="true"/>
<item android:drawable="#drawable/ic_closed_eye"/>
</selector>
Then just download two SVG icons (you can choose here your icons).
Lastly, just import them as "Vector Assets" in drawable folder and rename one ic_opened_eye, the other ic_closed_eye here you are, you can change your icons for password visibility.
Then just use app:endIconDrawable="#drawable/custom_eye" in your TextInputLayout.
If you still don't like it, just invert the two icons in the XML file whenever you want.
I am trying to add spaces between the tabs.
I would like to add gaps between the tabs, I have tried using padding but that changes the entire tab layout padding and not individual tabs. I have also tried other methods e.g. minWidth, while searching for an idea but couldn't figure it out, so i am here. Most of the project is default from when i created the tabbed layout activity, Here is the code i added/changed:
Thanks in Advance.

You should use xml drawable, specially designed for this purposes - Inset Drawable: http://developer.android.com/guide/topics/resources/drawable-resource.html#Inset
For example:
res/drawable/tab_selector_inset.xml:
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="#drawable/tab_selector"
android:insetRight="10dp"
android:insetLeft="10dp" />
And use it in your TabLayout:
app:tabBackground="#drawable/tab_selector_inset"
(Inspired by Vasily Sochinsky)
It is late but it may be useful for other people .if you have custom background for tabs(selector), you just need add layer list to tabs background and set margin for them
selector:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/bg_selected_tab" android:state_selected="true"/>
<item android:drawable="#drawable/bg_unselected_tab"/>
</selector>
selected tab:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:right="8dp" android:left="8dp">
<shape>
<stroke android:width="1dp" android:color="#color/Green"/>
<corners android:radius="#dimen/cardCornerRedius"/>
</shape>
</item>
</layer-list>
unselected tab:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:right="8dp" android:left="8dp">
<shape>
<stroke android:width="1dp" android:color="#color/Gray"/>
<corners android:radius="#dimen/cardCornerRedius"/>
</shape>
</item>
</layer-list>
I am using edittext and it's showing a line where I can enter text but I have seen examples of the line having upturned edges (see below). Can't figure out how to do it.
Edit text looks like this:
_____________.
but I want it to look more like this:
|__________________|
Thanks for help.
you need to use layer-list and add custom background to your edit text.
here's a sample.
create a xml file in your drawable folder-> custombg.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Border -->
<item>
<shape>
<solid android:color="#f000"></solid>
</shape>
</item>
<!-- Body -->
<item android:left="2dip"
android:bottom="2dp"
android:right="2dp">
<shape>
<solid android:color="#ffafafaf"></solid>
</shape>
</item>
</layer-list>
in you're edit text do this.
<EditText
android:id="#+id/edit_text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/border_line_withradius"
/>
I want a button that it has a background image and when I click that button,the button's background or color change (and we go to another activity.)
Tell me how can I make this.
Create an xml file and save it in one of the drawable folders in your project,let bg.xml,set this one as the background of your Button
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/button_pressed" android:state_pressed="true" />
<item android:drawable="#drawable/button_notpressed" />
</selector>
where button_pressed and button_notpressed are the images which you want to show on transition of the clicks and normal view of button
In your activity's xml file,set the background of the button as bg.xml
<Button
android:id="#+id/btn"
android:layout_width="150dp"
android:layout_height="60dp"
android:textSize="20dp"
android:layout_centerHorizontal="true"
android:layout_marginTop="450dp"
android:background="#drawable/bg" <--! set it like this-->
android:text="Submit"
android:textColor="#FFFFFF" />
I am trying following with android 2.3 as well as andorid 4.0.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#color/myColor"
android:orientation="vertical" >
<Spinner
android:id="#+id/spinnerControl"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:textColor="#android:color/white"
android:drawSelectorOnTop="true"
android:divider="#000000"
android:dividerHeight="1dp"
style="#style/Sherlock.__Widget.Holo.Spinner"
/>
</LinearLayout>
The style xml file is -
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Sherlock.__Widget.Holo.Spinner" parent="#android:style/Widget">
<item name="android:dropDownVerticalOffset">0dip</item>
<item name="android:dropDownHorizontalOffset">0dip</item>
<item name="android:dropDownWidth">wrap_content</item>
<item name="android:gravity">left|center_vertical</item>
<item name="android:spinnerMode">dropdown</item>
<item name="android:clickable">true</item>
</style>
</resources>
With android 4.0, I am getting spinner dropdown, right under the spinner control. But with andorid 2.3, it is coming in the middle of the screen, I don't know why. Please help.
To be precise, it was a new theme added to 4.0 by android. To get this style you need to provide the theme called "holo". But unfortunately it is not available for 2.X devices. And so you will not be able to get such a drop down in 2.X.
