I'm currently trying to implement Paralloid by chrisjenx for Android. It uses a FrameLayout that hosts two different layouts that take up the entire screen size. I need to perform an event during an ImageView's onClick(). The ImageView is located in the first layout.
For example:
<Frame Layout>
<Relative Layout>
<ImageView/>
<!-- Need this guys onclick, nothing outputted though. -->
</Relative Layout>
<chris.jenx.paralloid/>
</Frame Layout>
I've even gone as far as making sure Relative Layout and Image View both have clickable="true" and focusable="true". No Luck.
Have you tried setting the Image clickable property to true?
android:clickable="true";

In the following link: FrameLayout it is written:
FrameLayout is designed to block out an area on the screen to display a single item. Generally, FrameLayout should be used to hold a single child view, because it can be difficult to organize child views in a way that's scalable to different screen sizes without the children overlapping each other.
From the way i understand this quote, it means that it is recommended to add only one child to FrameLayout (although it possible to use more than one in order to make each view to overlap his "brother"). But, i can't understand the use of the FrameLayout only with one child, Let's say a LinearLayout. What is the difference between starting a layout file with a LinearLayout as the root of the xml file (see code 1), or wrapping it with a FrameLayout as the root, and then placing a LinearLayout has is son that will be the father of many other ViewGroup and View (see code 2)?
Code 2:
<FrameLayout
...>
<LinearLayout
...>
<ImageView .... />
<TextView .../>
</LinearLayout>
</FrameLayout>
code 1:
<LinearLayout...>
<ImageView.../>
<TextView.../>
</LinearLayout>
So I have this ScrollView inside which I have a RelativeLayout on one of my views on my Android app. Inside the RelativeLayout I already have a TableLayout that I'm using, and above it I want; 2 different text views (one header and one longer text, and I want the header to be placed on top of the longer bit of text) aswell as an ImageView that I want to be placed to the right of the 2 TextViews, and I want all 3 views to be placed on a differently colored background than the other stuff on the ScrollView such as the TableLayout for example.
I tried putting another RelativeLayout inside the ScrollView but it tells me ScrollView can only host one direct child, so that didn't really pan out. What would the most fitting way to accomplish this? Because I want this 3-view-background-thingie to scroll with the TableLayout and all the other stuff on the view.
As always, thankful for any answers or tips!
(My design kinda looks like this at the moment, schematically;)
<Container (that doesn't scroll)/>
<ScrollView
<RelativeLayout
*Alot of stuff here, such as a TableLayout for example
</RelativeLayout>
</ScrollView>
Put everything in your RelativeLayout
<ScrollView
<RelativeLayout
<LinearLayout>
<TextView>
</TextView>
<TextView>
</TextView>
<ImageView>
</ImageView>
</LinearLayout>
<TableLayout>
</TableLayout>
</RelativeLayout>
</ScrollView>
This way, the only child is the RelativeLayout, the others being children of the RelativeLayout.
Hope this helps!
Hey there I'm dealing with some kind of problem showing the softkeyboard in some android layout the layout ist organized like this:
<RelativeLayout>
<ScrollView>
Some stuff here...
</ScrollView>
<include ... />
<RelativeLayout>
I habe already set adjustPan and I have tried some experimental stuff with focusing. But my content inside the ScrollView is getting hidden by the included layout everytime its getting focus.
It may be just a logical problem but how do I tell e.g.: my EditText which is in the center of some other stuff like TextViews, ViewPager etc. to be above the included layout when gaining focus ?
I'm new to programming. I was using Graphical Layout then when I was reading xml file, I saw FrameLayout. Then I searched, but I couldn't find something useful. What is FrameLayout and what does it do?
You use a FrameLayout to stack child views on top of each other, with the most recent child on top of the stack. In the example below, the TextView is the most recent, so it is automatically placed on top of the ImageView.
For example:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="#+id/backgroundImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
android:src="#drawable/bitmapie" />
<TextView
android:id="#+id/descTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginTop="70dp"
android:background="#android:color/holo_blue_light"
android:padding="10dp"
android:text="TextView placed at the top of the Imageview"
android:textColor="#android:color/white"
android:textSize="22sp" />
</FrameLayout>
Output:
FrameLayout is the simplest implementation of ViewGroup. Child views are drawn are in a stack, where the latest added view is drawn at the top. Usually you can use one of the next approaches or combine them:
Add a single view hierarchy into FrameLayout
Add multiple children and use android:layout_gravity to navigate them
Another popular approaches of using FrameLayout:
as a Fragment container
as an ancestor of your custom ViewGroup
You can consider the word frame as regular photo frame. What you do with that frame? you can place photos in that frame by one top to another. Same as in FrameLayout we can place views ( Any layout, or widget like button, text, image so on) top of other as #ojonugwa shows you the textview top of the Image.
Are you sure that you googled it?

Frame Layout is designed to block out an area on the screen to display a single item. Generally, FrameLayout should be used to hold a single child view, because it can be difficult to organize child views in a way that's scalable to different screen sizes without the children overlapping each other.
You can, however, add multiple children to a FrameLayout and control
their position within the FrameLayout by assigning gravity to each
child, using the android:layout_gravity attribute.

The secret of FrameLayout is how it layouts its children. Although normally designed to contain one
item, it will happily stack up other element on top of each other.
Thus FrameLayout is essentially a way to manipulate the Z-order of
views on the screen.
This is super useful for a couple of UI tricks from HUD-like elements
to sliding panels to more complex animated transitions. In this post
we will see an example for each of those.

FrameLayout is designed to display a single item at a time. You can
have multiple elements within a FrameLayout but each element will be
positioned based on the top left of the screen. Elements that overlap
will be displayed overlapping. I have created a simple XML layout
using FrameLayout that shows how this works.
Basically it puts one view on top of another for example :
Inflating text on Image
<FrameLayout>
<ImageView>
<Textview>
</FrameLayout>
I have many activities with a scrollview inside a tablelayout. However, it is necessary a small design change, so I have to put a black transparent view over the whole screen from the top to the bottom. Is it possible to do it in the tablelayout or the scrollview?
RelativeLayout allows for easy overlapping of views. You'll have to adjust the existing views in your app because it doesn't do anything automatically.
EDIT:
A quick way to do this would be to take your existing view (the ScrollView) that is already organized and put it in a top-level RelativeLayout. Then, all you have to do is add new view inside the RelativeLayout with the width and height both set to MATCH_PARENT. The result should be the black transparent view will be visible over the ScrollView.
I normally use FrameLayout to achieve any kind of 'layering' of views.
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
//your existing layout
<View
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#33000000" />
</FrameLayout>
As DeeV said, you can probably use RelativeLayout in a similar way, but you might have to set additional attributes on its children to achieve this.
