I guess the pic pretty much explains it: is something like this possible?
Not really, as you can't have any type of Layout with this shape. But you can cheat a bit and make user to think it is like this. Just set content in layout B in the way you want.
You can use a RelativeLayout to achieve this type of layout.
<?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:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#00FFFF"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:layout_width="200dp"
android:layout_height="300dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:background="#FF0000"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
Nothing stops you from having overlapping layouts like in Krrishnaaaa's answer.
Depending on what Views you want to keep there you may try things similar to these, where you split fragment B into two separate:

I have little bit experience with Android and I'm not sure how to resolve this design problem. Maybe someone know a good solution. I like to build an Activity which look like this:
http://i.stack.imgur.com/CwQaU.png
The user should have to choice to drag the marker on the map or to enter the adress. I like to define the whole layout in XML without to extend from the map fragment.
Have someone a example how I can split the screen 80/20 with two fragments?
Are fragments are the right choice?
Just use a single fragment in this case. In your XML you'll want a LinearLayout so you can utilize weights to achieve the 80/20 you described above.
<LinearLayout>
<MapFragment/>
<EditText/>
</LinearLayout>
Give the linearLayout a "vertical" orientation and assign a weights of 4 and 1 to the children to split them 80/20%.
If this isn't enough to go off, let me know and I can explain further.
Good Luck!
You can use LinearLayout and play with the layout_weight parameter on the fragments to split the screen that way. Something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:name="name"
android:layout_width="match_parent"
android:layout_weight="4"
android:layout_height="0sp" />
<fragment
android:name="name"
android:layout_width="match_parent"
android:layout_weight="1"
android:layout_height="0sp" />
I don't think you need 2 fragments for this.
You can create one main LinearLayout with vertical orientation and inside set two RelativeLayout. One with map fragment and second with edittext.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_weight="3"
android:layout_height="0sp" >
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_weight="1"
android:layout_height="0sp"
android:background="#999">
<EditText
android:layout_width="200dp"
android:layout_height="wrap_content"
android:gravity="center"/>
</RelativeLayout>
</LinearLayout>
I am new to Android and am reading Wrox's professional android 4 app dev book. In chapter 4 of the book it explains how to modify the existing text view. The problem i am facing is that the listview in my app hides the edit text box. Its hidden (can be seen in the background) but still works that is more stuff can be added to the list through it. Below is the code for my main activity xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<EditText
android:id="#+id/myEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:contentDescription="#string/addItemContentDescription"
android:hint="#string/addItemHint"
/>
<ListView
android:id="#+id/myListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</RelativeLayout>
and my todolist_item xml
<?xml version="1.0" encoding="utf-8"?>
<com.example.wroxexample.ToDoListItemView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:scrollbars="vertical"
android:textColor="#color/notepad_text"
android:fadingEdge="vertical"
/>
The first option you have is to use a LinearLayout instead of a RelativeLayout.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<EditText
android:id="#+id/myEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:contentDescription="#string/addItemContentDescription"
android:hint="#string/addItemHint"
/>
<ListView
android:id="#+id/myListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
A RelativeLayout will allow you to position the elements relatively to the others.
On the other hand a LinearLayout will position the elements one below the other in the order they appear in the xml file.
The second option you have is to keep your RelativeLayout and just add the following tag to your ListView:
android:layout_below="#id/myEditText"
This will position the ListView below the EditText.
Try this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<EditText
android:id="#+id/myEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:contentDescription="#string/addItemContentDescription"
android:hint="#string/addItemHint"
android:layout_alignParentTop="true"
/>
<ListView
android:id="#+id/myListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/myEditText"/>
</RelativeLayout>
Use a LinearLayout and the property android:layout_weight
http://developer.android.com/reference/android/widget/LinearLayout.LayoutParams.html
Try something like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:id="#+id/myListView"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:entries="#array/testea"
android:layout_height="wrap_content"/>
<EditText
android:id="#+id/myEditText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/addItemContentDescription"
android:hint="#string/addItemHint"
/>
</LinearLayout>
This way ListView will grow to fill only the unused space.
Timothee got there before me but ill just add a little more.
you can, as he says, use a linear layout, or as user1387035 says, you can set the listview to be below the editText.
Relative Layout means "i want to lay things out relatively" and if you dont tell things where to go they will just float to where the 'gravity' is pulling them. The default gravity is top - so I'm guessing your items both ended up bunched at the top left?
As a rule of thumb - do you want your items to come one after another, bunched together (either horizontally or vertically)? if yes then use linear layout. If you want them to be pushed in different directions, use a relative layout. There are some exceptions, normally involving the "weight" attribute you can set in a linearlayout. (here's one I've just had to use: http://www.curious-creature.org/2010/08/15/scrollviews-handy-trick/)
If you have a Relative layout and are just using the layout_below/above attributes, without any 'alignParentBottom' or other thing set, then you probably just want a linearlayout
In your case I would say it sounds like you want Timothee's solution. If you want a little separation between the objects, you can use padding/margins to space them a little.
As for gravities, here is a useful blog entry that helped me get my head around LinearLayout's gravities (as well as generally): http://sandipchitale.blogspot.co.uk/2010/05/linearlayout-gravity-and-layoutgravity.html
I want to design a layout like in this image
Frame 1 is gray and he Frame 2 is transparent. I think we need to use FrameLayout but I don't know exactly how to use it.
Indeed you could use a FrameLayout or a RelativeLayout(at least for the Frame 1) but you don't say what exactly do you want to do with those frames(this will change things a bit). I would use a RelativeLayout because I'm guessing you'll have content in frame 1 besides frame 2:
<RelativeLayout android:id="#+id/frame1" android:background="#c1c1c1"// other attributes>
<FrameLayout android:id="#+id/frame2" android:layout_centerInParent="true"
android:background="#android:color/transparent"// other attributes />
</RelativeLayout>
one way can be:
<?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="fill_parent"
android:background="#c0c0c0" >
<LinearLayout
android:layout_width="200dp"
android:layout_height="100dp"
android:layout_centerInParent="true"
android:background="#ffffff"
android:gravity="center" >
</LinearLayout>
</RelativeLayout>
You can not make the above like screen using two frames, because it is not possible to put one frame in to the another frame layout, so you can make it by using another way like, take one relative layout and put the frame inside it like,
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/black" >
<FrameLayout
android:id="#+id/frameLayout1"
android:layout_width="250dp"
android:layout_height="100dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="180dp"
android:background="#color/tbl_green">
</FrameLayout>
</RelativeLayout>
may be this can help you.
I have got following xml structure of my app activity. Now I would like to remove child RelativeLayout programmatically with id layer1Front. How would I do that in code. I dont want to hide it, I need to remove it because of memory issues in my app. Also after removing it somehow will my app be lighter and faster than current one?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/layer1Front" >
</RelativeLayout>
<HorizontalScrollView android:layout_width="wrap_content"
android:layout_height="wrap_content">
<FrameLayout android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:id="#+id/parallaxLayers"
android:visibility="gone">
</FrameLayout>
</HorizontalScrollView>
<RelativeLayout android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/frontView">
</RelativeLayout>
</RelativeLayout>
Simplest would be
findViewById(R.id.layer1front).setVisibility(View.GONE);
But then you can also have something like
View root = findViewById(R.id.your_root);
root.removeView(yourViewToRemove);
No, your app is not going to be lighter or faster after removing it
Try fetching parent layout and than remove child
parentView.remove(child)
I hope this works.
I need your advice regarding my design and if you have a better idea (or you agree with me) that it is good. for some reason I have a feeling it is a "stone age programming style" but lets see.
Basically I have my xml relative layout. In the center (vertical and horizenatlly). I want to display "either" 3 buttons OR 3 texts depending on some user input. So what I did is the following:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clipChildren="false"
android:clipToPadding="false" >
<RelativeLayout android:id="#+id/Buttons"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" >
<Button1 .../>
<Button2 .../>
<Button3 .../>
</RelativeLayout>
<RelativeLayout android:id="#+id/Texts"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" >
<TextView1 .../>
<TextView2.../>
<TextView3.../>
</RelativeLayout>
</RelativeLayout>
Depending on the user input in the code I set visibility to either Visible or Invisible
Is this alright? and if not what do you suggest?
What you need is View.GONE, and View.VISIBLE.
With View.GONE - the layout doesn't occupy any space (almost as if it didn't exist at all). If you use View.INVISIBLE, to the user, the view (buttons, or text in your case) will not be visible, but they will still be there on the screen, thus shifting the other view (buttons, or text) up or down (the view won't be in dead center).
TIP: You can use 'android:layout_centerInParent' instead of 'android:layout_centerHorizontal' and 'android:layout_centerVertical'.
In my opinion, what you have done may be primitive, but it is simple, which is good :) But if you still want some options and make life complicated, then
Put each of the blocks in a separate xml and use include.
Make 2 views and then use ViewFlipper to flip them based on user requirements.
But for the simple requirement that you have, I think u r doing fine.
The include option would work something like this,
layout_1.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/Buttons"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" >
<Button1 .../>
<Button2 .../>
<Button3 .../>
</RelativeLayout>
layout_2.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/Texts"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" >
<TextView1 .../>
<TextView2.../>
<TextView3.../>
</RelativeLayout>
your main_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clipChildren="false"
android:clipToPadding="false" >
<include layout="#layout/layout_1" />
<include layout="#layout/layout_2" />
</RelativeLayout>
The include helps you in making reusable layouts and also helps in keeping your xml files grow out of proportions, specially when you have complicated UIs.
First option is:
You can add all the three buttons or textviews in Linearlayout and center it in parent by using android:layout_centerInParent.
Second option is:
You can center the middle button out of all the three buttons and adjust the other two buttons with respective to the middle button. Same way we should also repeat this for textviews. In this option, we should make all the three views visibility to View.GONE explicitly.
