I have in main.xml TitlePageIndicator and ViewPager, and I want to add admob (right into LinearLayout) at the bottom of RelativeLayout. How can I do this?
When I launch it, the log says nothing about errors (since there is no place to put admob), but admob is invisible, I can`t see it. (looks like admob is outside the screen because I tried to set specific sizes to ViewPager and it works perfect)
I do not want to set specific sizes to ViewPager (becouse of the different screen sizes)
Thanks.
My main.xml is:
<?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">
<com.viewpagerindicator.TitlePageIndicator
android:id="#+id/indicator"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"/>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/indicator"/>
<LinearLayout
android:id="#+id/for_ads"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/viewpager"/>
</RelativeLayout>
UPD.
solved
I used this answer and it works perfect for me
First, your RelativeLayout needs an ID if you want to reference it:
RelativeLayout rLayout = (RelativeLayout)findViewById(R.id.yourRelativeId);
Then create some LayoutParams for the object (in this case, your admob adview) that tell it to align itself to the bottom (and not align to any other views, this way it isn't pushed off-screen or moved by the other views):
RelativeLayout.LayoutParams rLParams =
new RelativeLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
rLParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 1);
Next, add the view to your RelativeLayout with your LayoutParams:
rLayout.addView(yourAdView, rLParams);

I'm trying to split my screen into different sizes using four Linear layouts within a linear layout. When I add weights to my project, it shows on the screen that the layout is split into 4 even parts on the layout preview. But when I run the app on a device or emulator, the views are not shown. But when I remove the weight attributes, the views are shown.
I've used code samples which successfully used the weight property but don't work on my program. I've also programmatically got the width and height of all the sub-views on the code. They are not null so they are there but just not visible. I've tried adding properties like visibility = true and focusable = true but to no avail. I've added a drawView to the view using this code
DrawView drawView = new DrawView();
ViewGroup mainLayout = (ViewGroup) findViewById(R.id.main);
mainLayout.addView(drawView);
DrawView is a class that extends View and I call the methods canvas.drawLine() and canvas.drawText() to draw to the screen
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:id="#+id/main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:weightSum="4">
<LinearLayout
android:visibility="visible"
android:focusable="true"
android:id="#+id/l1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"

android:orientation="horizontal"></LinearLayout>
<LinearLayout
android:visibility="visible"
android:id="#+id/l2"
android:orientation="horizontal"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#color/colorBtnText"></LinearLayout>
<LinearLayout
android:id="#+id/l3"
android:orientation="horizontal"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#color/colorBtnBackground"></LinearLayout>
<LinearLayout
android:id="#+id/l4"
android:orientation="horizontal"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#color/colorLbl"></LinearLayout>
</LinearLayout>
Nothing I tried above worked. I've spent quite a bit of time on this and would really appreciate some feedback.
I think the DrawView need setLayoutParams(LinearLayout.LayoutParams) before add to LinearLayout, set fixed height or weight by LayoutParams. if you don't, DrawView height is MATCH_PARENT, that will make other view's height is 0.
you can try this:
DrawView drawView = new DrawView();
LinearLayout mainLayout = (LinearLayout) findViewById(R.id.main);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,0, 1); // or new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,100); to set fixed height
mainLayout.addView(drawView, params);
If it work, i think the best way is DrawView override onMeasure method, and calculate height itself.
As you can see, you set the "android:weightSum" to 4 in your xml file. While it still have 4 childs under the main linear layout, the code shows no error. However, when you run your code, you programmatically add another view into your main linear layout which exceed the weight sum of your main layout.
So, what i would suggest is, you may try to remove the android:weightSum="4" attribute from your xml layout that way it will automatically calculate the layout size by its weight.
I have a fragment with two RelativeLayout, one inside the other. This fragment is inside a tab. I want that the internal layout(layoutInternal) is scrollable, but with the following code does not work. I create the view object into the layoutInternal dinamically. Where is my mistake?
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layoutExsternal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginBottom="#dimen/fragmentHall_10dp_margin"
android:layout_marginTop="#dimen/fragmentHall_10dp_margin">
<RelativeLayout
android:id="#+id/layoutInternal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</RelativeLayout>
</ScrollView>
</RelativeLayout>
The following code is where i insert the view object (table) inside the intenalLayout.
while (iteratorTables.hasNext()) {
[...] //Here i calculate the dimension and coordinates
b_table = new ButtonTable(SelzApplication.getAppContext(),tableMap.getValue(), widthTable, heightTable);
b_table.setX(Math.round((tableMap.getValue().getX())* Xratio));
b_table.setY(Math.round((tableMap.getValue().getY())* Yratio));
//add Touch Listeners to the button
b_table.setOnLongClickListener(new OnLongTuchDragDrop());
b_table.setOnClickListener(new TableOnClick());
layoutInternal.addView(b_table, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
This is the screenshot of my app.
The RelativeLayout layoutInternal has the height initially set as android:layout_height="wrap_content" but its content is initially empty because the content is created dynamically; for this reason is not scrollable.
To solve this, when you finish to draw the tables into RelativeLayout layoutInternal, you have to set its height dynamically as below:
FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) layoutInternal.getLayoutParams();
params.height = max_y_coordinate_used;
layoutInternal.setLayoutParams(params);
I'm using a screen that I want to switch between layouts on the click of a button. I want both layouts to occupy the full height of the screen, when the button on the first layout is pressed, i want this layout to disappear and the other layout to take it's place, and then same on the next layout.
<LinearLayout
android:id="#+id/layoutFirst"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
..... views
</LinearLayout>
<LinearLayout
android:id="#+id/layoutSecond"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
..... views
</LinearLayout>
On each layout I have a button. I want this button to switch so the other layout occupies the full screen, but nothing happens. The code in the on-click event for the first screen is the following
LinearLayout layoutFirst = (LinearLayout) this.findViewById(R.id.layoutFirst);
layoutFirst.setVisibility(View.GONE);
LinearLayout layoutSecond = (LinearLayout) this.findViewById(R.id.layoutSecond);
layoutSecond.setVisibility(View.VISIBLE);
Just in case the problem was to do with the fill_parent, I also tried this with the height being set to wrap_content. Initially I can see both layouts on the screen, when I press the button, the layout still does nothing.
Can anyone tell me if I am doing something wrong or if there's a way to solve this issue. Any help would be greatly appreciated it
Put the two LinearLayouts inside a FrameLayout:
<FrameLayout
android:id="#+id/framelayout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/layoutFirst"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:visibility="gone">
</LinearLayout>
<LinearLayout
android:id="#+id/layoutSecond"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>
Give the LinearLayouts different ids!
Is your parent layout a "RelativeLayout" ? => not necessary here.
Try also the solution proposed in this quite similar thread how to hide linearlayout from java code?
Update:
/*global or add final keyword if not global in order to use inside listener */
LinearLayout layoutFirst;
LinearLayout layoutSecond;
/*end global*/
/*in onCreate(Bundle) method*/
layoutFirst = (LinearLayout) this.findViewById(R.id.layoutFirst);
layoutSecond = (LinearLayout) this.findViewById(R.id.layoutSecond);
/*and then in your listener, alternatively*/
layoutFirst.setVisibility(View.GONE);
layoutSecond.setVisibility(View.VISIBLE);
SOLVED: The layout_height parameter was set to Match_parent in the buttonbar definition. Changed to wrap_content.
I'm currently working on a new App which has a series of buttons at the top of the main screen. the "buttonBar" XML defines a linearLayout and is later nested within another linearLayout.
The buttons appear fine and work however if I then put a text view beneath the include statement the text does not appear. I think that it is actually appearing behind the buttons. I assumed that because it was within a parent linearLayout that it would appear after the included (nested) nested layout.
please could someone explain why this is not occurring and point me in the right direction to solve it.
much appreciated,

<?xml version="1.0" encoding="utf-8"?>

Set height and width of the included layout buttonheader
SO that you can see this included layout in your layout
In my app, I have one (and only one) UI element which isn't referenced in the XML layout file.
That element is a button, instantiated and returned at run-time by a 3rd party library (i.e. I don't have control over that).
My problem is that I would like some of the elements (TextViews) in the XML layout file to be placed relative to that button, using RelativeLayout.
Is it possible to "reserve an empty slot" in the XML layout file for that button such that I can do something like the following?
<TextView android:id="#+id/tv_text_under_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/btn_dynamically_created_button"
android:text="" />
Alternatively, if I were to set the layout at run-time using RelativeLayout.LayoutParams.addRule(), what would be the ID of that dynamically created button, if it has no reference at all in the XML layout file?
For example, in the following call:
layoutParams.addRule(RelativeLayout.BELOW, R.id.btn_dynamically_created_button);
What would I put instead of R.id.btn_dynamically_created_button?
Update: Thanks to the answer below, I created a place holder like this:
<LinearLayout android:id="#+id/btn_dynamically_created_button"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</LinearLayout>
The challenge now is: How to associate the returned object from getDynamicallyCreatedButton() (returned object is subclass of LinearLayout, not Button), with R.id.btn_dynamically_created_button?
EDIT: This thread seem to address a similar issue, but I am not sure that I understand the solution offered.
I'd suggest:
Put a LinearLayout with width/height set to wrap-content, horizontal orientation and zero padding as the placeholder.
Orient all the other things to that LinearLayout.
When its time to put the button, simply stick it into the LinearLayout.
See if that works for you.
EDIT: attempt at a short example:
The layout (suitably shortened): you can place other components relative to the LinearLayout with id LinearLayout01.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_marginTop="2sp" android:layout_marginBottom="2sp" android:layout_height="wrap_content">
<LinearLayout android:id="#+id/LinearLayout01" android:layout_height="wrap_content" android:layout_width="wrap_content" android:gravity="right" style="#style/SimpleButtonBar" android:layout_below="#+id/rootlayout" android:layout_alignParentBottom="true">
</LinearLayout>
<ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_above="#+id/LinearLayout01" android:fillViewport="true">
<RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="#+id/detaillayout">
</RelativeLayout>
</ScrollView>
</RelativeLayout>
The code (for example, this would go in onCreate): fetch your button (you need to make sure it has the right Context, but I figure you're doing that alright), fetch the LinearLayout, create a layout parameters object and stick your button into the LinearLayout.
Button b = getButton(); // retrieve your button somehow
LinearLayout l = (LinearLayout)findViewById(R.id.LinearLayout01);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
l.addView(b, lp);
