I am trying to add a custom background to a button to make two sides rounded. But when I attach or add custom view background, the button becomes invisible. Here is my xml code:
<android.support.constraint.ConstraintLayout
Have Some Code there

Now I want to have different styling for activity toolbar when top level fragment is loaded and when its child is loaded (showing back arrow in toolbar).
QUESTION: How can I achieve this different styling for toolbar (appbar) if I use Android Navigation Component and I navigate from root fragment to child fragment using the following code:
Bundle bundle = new Bundle();
bundle.putString("id", ei.id);
MainActivity)context).getNavController().navigate(R.id.action_actualFragment_to_actualEventFragment, bundle);
NavigationUI uses an AppBarConfiguration object to manage the behavior of the Navigation button. The Navigation button’s behavior changes depending on whether the user is at a top-level destination. Have a look at their documentation Update UI components with NavigationUI
I am trying to use Navigation View in Drawer Layout, but I keep getting errors when building the file.
Here's what my xml looks like:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/contentFrame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/navigation_items"
/>
</android.support.v4.widget.DrawerLayout>
This leads to a build gradle error. My menu looks like this:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item android:id="#+id/menu_bookmark"
android:title="Bookmark" />
<item android:id="#+id/menu_save"
android:title="Save" />
<item android:id="#+id/menu_search"
android:title="Search" />
<item android:id="#+id/menu_share"
android:title="Share" />
</group>
</menu>
When I remove app:menu from the navigationView,the error goes away. What could be wrong?
My fix was that I needed to add app:headerLayout="#layout/my_header_layout" as well.
I'm using a GridLayout in Xamarin to create a Calculator app and am having trouble getting it to fill the screen. One possible solution I found was to use a LinearLayout for each row of the controls. The problem with this is that my = button spans two rows and I wasn't able to use it. I have also tried changing the GridLayout's layout_width and layout_height with no luck. What other options do I have? Here's my code and some screenshots:
<?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">
<GridLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:columnCount="4"
android:orientation="horizontal">
<TextView
android:text="0"
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_columnSpan="4"
android:gravity="right"
android:layout_gravity="fill"
android:id="#+id/resultView" />
<Button
android:text="Del"
android:id="#+id/button1" />
<Button
android:text="C"
android:id="#+id/button1" />
... <!-- Buttons continue -->
<Button
android:text="3"
android:id="#+id/button1" />
<Button
android:text="="
android:layout_gravity="fill"
android:layout_rowSpan="2"
android:id="#+id/button1" />
<Button
android:text="0"
android:layout_columnSpan="2"
android:layout_gravity="fill"
android:id="#+id/button1" />
<Button
android:text="."
android:id="#+id/button1" />
</GridLayout>
</LinearLayout>
What I have:
What I want:
Edit: I know each button has the same id, but I'm only concerned with getting the layout right at the moment.
I have the following layout set to Orientation = vertical. But when I rotate the emulator to Landscape, it show the Layout in Landscape.
I want the Layout be in orientation vertical even the device rotate to Landscape.
How to solve this problem? Appreciate your help.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/myLinearLayout"
android:minWidth="25px"
android:minHeight="25px">
<TextView
android:id="#+id/myLabel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Put Your Name here :" />
<EditText
android:id="#+id/myEditBox"
android:inputType="textMultiLine"
android:textColor="#android:color/background_dark"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/myButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hey! Click Me" />
</LinearLayout>
android:orientation="vertical" means that the children are inserted into the layout vertically. So when you add more views they will stack underneath each other.
Vertical:
Horizontal:
This is the layout I used. Try change the orientation on your own and see the effect:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<View
android:background="#aabbdd"
android:layout_width="50dp"
android:layout_height="50dp" />
<View
android:background="#341233"
android:layout_width="50dp"
android:layout_height="50dp" />
<View
android:background="#123456"
android:layout_width="50dp"
android:layout_height="50dp" />
<View
android:background="#654321"
android:layout_width="50dp"
android:layout_height="50dp" />
<View
android:background="#550000"
android:layout_width="50dp"
android:layout_height="50dp" />
</LinearLayout>
If you want to lock rotation in your Activity, you need to add the following property to your ActivityAttribute:
ScreenOrientation = ScreenOrientation.Portrait
So it will look something like:
[Activity(Label = "Herp Derp", ScreenOrientation = ScreenOrientation.Portrait)]
public class HerpDerpActivity : Activity
{
// more stuff here
}
I have two radio buttons, which looks like a normal buttons. I would like to change their background color by using radio_button.xml with selector inside.
If I use little .png image to set background then it works fine.
But I tried similar code to use just colors (integers) and it doesn't work. What I'm doing wrong?
Code with background image:
<RadioGroup
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RadioButton
android:text="LEFT"
android:id="#+id/radioLeft"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:background="#drawable/radio_button"
android:checked="true" />
<RadioButton
android:text="RIGHT"
android:id="#+id/radioRight"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:background="#drawable/radio_button" />
</RadioGroup>
radio_button.xml
<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#drawable/gray_dot" />
<item android:state_checked="false"
android:drawable="#drawable/blue_dot" />
</selector>
button_colors.xml
<?xml version="1.0" encoding="utf-8" ?>
<resources>
<color name="button_black">#000000</color>
<color name="button_white">#ffffff</color>
<color name="button_blue">#00afdb</color>
<color name="button_gray">#dcdcdc</color>
</resources>
I tried to replace
android:drawable="#drawable/blue_dot"
with
android:background="#color/button_blue"
but it's not working. How to fix?
I used shape xml with color to avoid background images.
radio_button.xml
<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#drawable/rb_checked" />
<item android:state_checked="false"
android:drawable="#drawable/rb_unchecked" />
</selector>
rb_checked.xml
<?xml version="1.0" encoding="utf-8" ?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#color/button_blue" />
</shape>
Main.axml
<RadioGroup
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RadioButton
android:checked="true"
android:text="LEFT"
android:id="#+id/radioLeft"
android:button="#android:color/transparent"
android:background="#drawable/radio_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center" />
<RadioButton
android:text="RIGHT"
android:id="#+id/radioRight"
android:button="#android:color/transparent"
android:background="#drawable/radio_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center" />
</RadioGroup>
The trick that worked for me was
radioLeft.ButtonDrawable.SetTint(GetColor(Resource.Color.button_blue));
Or whatever color you wish to set, depending on the checked state, eg
radioLeft.ButtonDrawable.SetTint(GetColor(radioLeft.Checked ? Resource.Color.button_blue : Resource.Color.button_gray));
