how to adjust flipper size in your android studio project? - android-layout

I wanted to create slideshow in my main activity page. After implementing the flipper inside my app, I notice that the FlipperLayout got overlapped with my widget Toolbar. Inside my widget toolbar contains name of the user, where I call the user full name when they are logged into the app.
I'm not quite sure on how to adjust the flipper size to make sure that the slideshow will not overlap with my toolbar. And I want the flipper to be put below the toolbar. Can anyone help me ?
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/frame_layout"
android:layout_above="#id/btm_nav"
>
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/purpleBoo"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark" >
<TextView
android:id="#+id/tv_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="welcome"
android:layout_gravity="center"
android:textColor="#color/white">
</TextView>
</androidx.appcompat.widget.Toolbar>
<technolifestyle.com.imageslider.FlipperLayout
android:id="#+id/flipper"
android:layout_width="match_parent"
android:layout_height="219dp">
</technolifestyle.com.imageslider.FlipperLayout>

You can edit your FlipperLayout to add android:layout_marginTop="?attr/actionBarSize" attribute
<technolifestyle.com.imageslider.FlipperLayout
android:id="#+id/flipper"
android:layout_width="match_parent"
android:layout_height="219dp"
android:layout_marginTop="?attr/actionBarSize">
OR
You can use a LinearLayout at the root of your layout instead of a FrameLayout, with android:orientation="vertical". This is because the FrameLayout is intended for purposes where child view overlapping is desired.

Wrapping two ScrollViews into a LinearLayout

I am struggling to find a solution for one of the Android Studio (Kotlin) class problems by Google: how to add another image that scrolls down with the first ScrollView. I created a LinearLayout that has two ScrollViews within it. The first ScrollView has a large amount of text which scrolls down perfectly. However, in the second ScrollView, for the image above the text, it does not scroll down with the text.
Here is a view of the Design element of the activity_main (the green bar below the star is ImageView1 which is in the second ScrollView):
Here is the code for the ScrollViews in my activity_main:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:id="#+id/bio_scroll2"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/imageView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:srcCompat="#android:drawable/button_onoff_indicator_on" />
</ScrollView>
<ScrollView
android:id="#+id/bio_scroll"
android:layout_width="match_parent"
android:layout_height="463dp">
<TextView
android:id="#+id/bio_text"
style="#style/NameStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:lineSpacingMultiplier="1.2"
android:text="#string/bio" />
</ScrollView>
</LinearLayout>
Some guidance will be greatly appreciated.
The reason I told you to use only one ScrollView is that you don't need two. You can use any number of views in a Scrollview, just make sure the child of ScrollView is a Layout. You can use any layout and then put whatever you have in that layout. That's how ScrollView is used.
As the official docs of ScrollView state :
Scroll view may have only one direct child placed within it.
To add multiple views within the scroll view, make the direct child
you add a view group, for example LinearLayout, and place additional
views within that LinearLayout.
So, change your code as :
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:id="#+id/bio_scroll2"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="#+id/imageView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:srcCompat="#android:drawable/button_onoff_indicator_on" />
<TextView
android:id="#+id/bio_text"
style="#style/NameStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:lineSpacingMultiplier="1.2"
android:text="#string/bio" />
</LinearLayout>
</ScrollView>
</LinearLayout>
Furthermore, You can remove the root LinearLayout if you don't want to add any other view in it and that will make the ScrollView the root layout.
Also, the height as match_parent doesn't work in ScrollView and it works only as wrap_content or any fix size so if you want to make it take the full height of its parent, you've to use android:fillViewport="true" in ScrollView's tag and height of its parent should be match_parent.

Keyboard Panel to choose diiferent views(Custom)

I need to make a Panel on which I'll be able to switch between different custom keyboard views that i have designed.
Something like this
My keypad with navigation panel and custom view of my Numeric keypad
At least two strategies can be applied.
Put your custom KeyboardView inside another ViewGroup, ex.:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
\>
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Wazup?!"
/>
<org.dodroid.customime.CustomKeyboardView
android:id="#+id/keyboard"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:keyBackground="#drawable/samplekeybackground"
android:keyPreviewLayout="#layout/preview"
android:popupLayout="#layout/keyboard_popup_keyboard"
/>
</LinearLayout>
Instead of TextView can be your custom panel.
Create one more Row at top with navigation buttons.

Android clickable layouts above empty views

My project also uses Xamarin with MvvmCross, but I don't think this will effect the answer since the problem is all view-layout/axml related.
I have a GridView that summarizes a list of contacts. When clicking on this grid view, I would like the user to be taken to another screen to add more contacts to this list (so there is more space).
Subscribing to the GridView's OnClick event gives me an exception, saying I should be subscribing to the item click event, so I have done this using a clickable relative layout that surrounds the GridView (and its accompanying empty image view) as such:
...
<RelativeLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:id="#+id/addContactsRelativeLayout"
android:clickable="true">
<ImageView
android:id="#+id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="#drawable/ic_add" />
<Mvx.MvxGridView
android:id="#+id/addContactsGridView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
local:MvxBind="ItemsSource Contacts"
local:MvxItemTemplate="#layout/contact_summary_item"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:columnWidth="55dip"
android:gravity="center" />
</RelativeLayout>
...
This works fine when the GridView is empty, and the empty ImageView is shown. However, when there are items in the GridView, the RelativeLayout no longer seems to exist and clicks over the GridView can be seen to highlight items on the GridView. This means the user is not taken to the screen to edit their contact list.
I have tried several different configurations and attributes from similar questions on SO, but I think the addition of an empty view is causing problems. Any help would be greatly appreciated.
Ok, after a lot more playing around I found a solution.
Essentially it's adding another relative layout, higher in the z-index and therefore above the 'real' contents, within the surrounding relative layout.
...
<RelativeLayout
android:layout_height="wrap_content"
android:layout_width="match_parent">
<ImageView
android:id="#+id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="#drawable/ic_add" />
<Mvx.MvxGridView
android:id="#+id/addContactsGridView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
local:MvxBind="ItemsSource Contacts"
local:MvxItemTemplate="#layout/contact_summary_item"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:columnWidth="55dip"
android:gravity="center"
android:focusable="false"/>
<RelativeLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:clickable="true"
android:id="#+id/addContactsRelativeLayout"/>
...
Then just move all your click listeners to listen to the relative layout at the bottom.

Custom action icon on android devices

I am developing custom menu item by calling action layout, but when i am taping that action menu that pressing color is not applying total height giving some top and bottom margin.
Below is my code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<ImageView
android:minWidth="56dp"
android:id="#+id/voicemailNotificationCounter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:clickable="true"
android:background="#drawable/ab_pressedicon_bgcolor"
android:contentDescription="#string/voicemailnotification"
android:src="#drawable/ab_voicemail">
</ImageView>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/vmNotificationTextCounter"
android:text="1"
android:visibility="visible"
android:layout_alignRight="#+id/voicemailNotificationCounter"
android:layout_marginRight="10dp"
android:gravity="center"
android:textColor="#fff"
android:includeFontPadding="false"
android:background="#drawable/notification_alertbg"
android:textSize="12sp"/>
</RelativeLayout>
Part of the problem is that you're not using an ImageButton.
Combining an image with text is possible with an ImageButton. You can even independently adjust the text and the image inside that ImageButton.
Hopefully, an ImageButton will work inside an action menu, I haven't actually tested that part yet.

Android app RelativeLayout not showing

so im trying to use a relative layout (for basic app tabs at the bottom of the screen) and it is not showing when i place it inside the LinearLayout after 2 other layouts (a LinearLayout and a ScrollView). The ScrollView contains several textViews and scrolls nicely on its own and the linearlayout before it also works nicely, but the relativelayout that i have tried to place at the bottom of the screen does not work.
Here is the general code for what i am trying to do:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:orientation="vertical"
android:background="#drawable/common_bg"
android:layout_height="fill_parent">
<LinearLayout android:layout_width="fill_parent"
android:layout_height="50dp">
<TextView android:layout_height="50dp"
android:text="Heading"
android:gravity="center"
android:textSize="17dp"
android:textColor="#color/white"
android:textStyle="bold"
android:layout_width="fill_parent">
</TextView>
</LinearLayout>
<ScrollView android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="none"
android:layout_gravity="top"
android:layout_marginBottom="60dp">
<LinearLayout android:layout_width="fill_parent"
android:orientation="vertical"
android:paddingTop="15dp"
android:layout_weight="1"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:layout_height="fill_parent">
<TextView android:layout_width="wrap_content"
android:textColor="#color/white"
android:textSize="18dp"
android:textStyle="bold"
android:text="#string/text"
android:layout_height="wrap_content">
</TextView>
</LinearLayout>
</ScrollView>
<RelativeLayout
android:id="#+id/bottomMenu"
android:layout_width="wrap_content"
android:layout_height="60dp" />
</LinearLayout>
UPDATE: the Relative layout that im using is custom in a way that i cant actually show the code for it here, but it contains a radio group with several buttons.
UPDATE 2: Ok, so I solved the problem by manipulating the layout_height="wrap_content" on the 3 layouts (the first linear, the one holding the scroller, and the bottom relativelayout) as well as manipulating the layout_wieght of each of them until I was satisfied with the way it looked... it doesnt seem like this is the best possible solution, but it worked so i cant complain too much lol...
The relative layout in itself wont be displayed in an xml graphical layout or when you are running the app, it needs a child element to occupy the parent layout, try putting a text view inside the relative layout, it'll be displayed, position it right below the linear layout having the scroll view, it'll work properly, i just tried it with your code and it works
