today I'm facing an issue with the layouts in android.
This is my goal :
I wan't a popup with a Title, a body containing a scrollView (in case of Big data) and a button.
This is what my layout look like in the big lines:
<RelativeLayout
android:id="#+id/popup_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#FF0000">
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:text="Title"/>
<ScrollView
android:id="#+id/body_scrollview"
android:layout_width="wrap_content"//To permit the scrollview to resize depending of the data amount
android:layout_height="wrap_content"
android:layout_below="#id/title"
android:layout_centerHorizontal="true"
android:layout_marginTop="10dp">
<TextView
android:id="#+id/body_txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My very long sentence which may take all the screen size and maybe more"/>
</ScrollView>
<Button
android:id="#+id/confirm"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#id/body_scrollview">
</Button>
</RelativeLayout>
If the text is short, then no issue, the button is still visible, but if the text is very big (I mean bigger than the screen can support) the button disappears.
I could do a bottom alignment with the button and then put the above property inside the scrollView but it will cause the popup to always take all of the height size (even if the text is very small) which is not what I want.
Any idea of how I should do it ?
Thank you by advance.

I'm trying to build the following layout on Android without any success.
I want a text to be displayed on my screen. It can take the whole width, but must be centered horizontally.
On the same line, on the right side of the screen I want to display a small layout. It shouldn't impact the horizontal centering of the main text and the main text shouldn't be visible behind the layout displayed on the right.
I cannot use a hard color for my layout background as it's displayed on a transparent background over a bitmap...
Any idea on how to achieve this ?
I can either use a RelativeLayout in which case the main text isn't centered based on the middle of the screen (it takes the right layout width into account)
Or the text is displayed behind the right layout...
Edit:
Here is one of my test
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:orientation="horizontal" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="bottom|center_horizontal"
android:layout_centerInParent="true"
android:fontFamily="sans-serif"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:singleLine="true"
android:textColor="?android:attr/textColorPrimary"
android:textSize="17sp"
android:text="very looooooooooooooooooooooooooooooooong text"
android:textStyle="bold" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_centerInParent="true"
android:layout_alignParentRight="true"
android:padding="3dp"
android:visibility="visible" >
<ImageView
android:layout_width="24dp"
android:layout_height="24dp"
android:layout_gravity="center_vertical"
android:filter="true"
android:src="#drawable/device_access_time" />
<Spinner
android:layout_width="20dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
</RelativeLayout>
RelativeLayouts adhere to the principle of z-indexes, so if you put the right-aligned layout first, the centered text view will be drawn correctly on top.
I am trying to achieve the look of Facebook's event page and am having trouble copying their three buttons that say if a person is going to an event.
I am trying to achieve this,
Mine currently looks like this,
This is the XML for the buttons
<LinearLayout
android:id="#+id/button_holder"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="3"
android:layout_marginLeft="10dp"
android:layout_marginStart="10dp"
android:paddingBottom="10dp">
<Button
android:id="#+id/button_going"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textSize="14sp"
android:textColor="#color/secondary_text"
android:text="Going"
android:background="#drawable/item_left_button_background"/>
<Button
android:id="#+id/button_maybe"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textSize="14sp"
android:textColor="#color/secondary_text"
android:text="Maybe"
android:background="#drawable/item_middle_button_background"/>
<Button
android:id="#+id/button_decline"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textSize="14sp"
android:textColor="#color/secondary_text"
android:text="Decline"
android:background="#drawable/item_right_button_background"/>
</LinearLayout>
I do not know where the extra Padding or Margin is coming from above and below my buttons. I have tried android:padding="0dp" and android:layout_margin="0dp" on the buttons but it had no effect.
My best guess is it might have something to do with the layout_weight attribute. This may give the buttons a certain height based on their width, if this is the case then how can I make the buttons shorter?
AS you are applying the background item_left_button_background so that must be an image or selector which consists images those images have a specific height. When you give the button height as wrap_content it will take by default what is height of the image so as per my suggestion give a specific height to the button or create the background images as per your required sizes
I'm attempting to create a a Heading + button similar to the Google Music App, e.g. where there is a "Songs" Header on the Left and then on the right there is a Button with the text "X more"..
I've using a RelativeLayout for the TextView and Button
My problem is that the button is taking up the size of the layout that contains the text the height is all wrong and the padding doesn't seem to do anything.
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
[REMOVED for clarity]
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/list_foreground"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="#string/photos"
android:textAppearance="?android:attr/textAppearanceMedium" />
<Button
android:id="#+id/photo_button"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:background="#color/actionbar_background"
android:padding="10dp"
android:text="test" />
</RelativeLayout>
What am I doing wrong here?
RelativeLayouts are designed to have children in the layout "relative" to each other. In other words, if you want the Button to the right of the Textview, you need to tell it.
Because you are aligning relative to the parent LEFT / RIGHT, it appears that things are "kind of" working.
You may be better off with a LinearLayout, depending on your needs. LinearLayouts use "orientation" not RelativeLayouts.
You should look over some tutorials (like this one: http://mobile.tutsplus.com/tutorials/android/android-layout/) but ultimately you will probably put your button in first and then your text view so that the textview content will wrap appropriately.
To get the same effect as the Music App I ended up using a RelativeLayout but instead of a Button I'm using another TextView, this is giving the impression it's a button but it gives me more scope to format the background etc. I think just setup a OnClickListener in the code
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/photo_title">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="10dp"
android:text="#string/photos"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/more_photo_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:background="#color/actionbar_background"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:text="10 MORE"
android:textColor="#color/button_text"
android:textSize="12sp" />
</RelativeLayout>
I wanted to make two equally-sized radio buttons with a custom background, text, and an image to the right of the text. Because of how different these are from a standard "Button", I made them using a clickable "RelativeLayout".
The text and the image are of different heights, but I want each one to be centered vertically in the button. I also want the combination of the text+image to be centered horizontally in the button. This second part is what I'm having trouble with; it's off-center, close to the left side. In the image below, the left side is what I want, but the right side is what's happening. The image on one of the buttons (the one with the longer text) is resized to be smaller, too... Though there is still plenty of space on the right side of the button.
Here is my code:
<LinearLayout
android:baselineAligned="false"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RelativeLayout
android:id="#+id/my_button"
android:background="#drawable/radio_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<TextView
android:id="#+id/button_textview"
android:text="#string/button_label"
android:textAppearance="?android:attr/textAppearanceButton"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<ImageView
android:contentDescription="#string/image_description"
android:id="#+id/button_imageview"
android:layout_centerVertical="true"
android:src="#drawable/my_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/button_textview">
</ImageView>
</RelativeLayout>
<RelativeLayout
... same thing for the second button ...
</RelativeLayout>
</LinearLayout>
What am I doing wrong?
Use this as your button:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_gravity="center_horizontal"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="MyButton"/>
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:src="#drawable/my_image"/>
</LinearLayout>
Now, you can place it in other parent views. To apply layout attributes to above button, place those attributes in the outer <LinearLayout> tag of above button.
Alternative:
You can set custom images to be drawn on sides(Left,Right,Top,Bottom) of a TextView using attributes like:
android:drawableLeft="#drawable/my_image"
Turns out the solution was adding
android:paddingRight="0dip"
strangely enough, even though I didn't put any padding there in the first place.
I have two custom RadioButtons side by side that fill the width of the screen. I want to have text and an image to the right of the text, centered in the button.
drawableRight draws the image way off to the right of the button, not near the text. I can't use drawableEnd because I don't have Android 4.0
I've tried using a Spannable, but the problem with that is that the image is bigger than the text. I don't want it aligned with the bottom or baseline of the text; I want it to be centered in the button on its own.
The best solution I've found is making a clickable RelativeLayout with a TextView and ImageView centered in it. This makes the button look the way I want it to, but it seems like a lot of work to do that, and to program each RelativeLayout to act like a RadioButton in a RadioGroup.
Is there an easier way, or something that I'm missing? Or should I keep my RelativeLayout idea? Here's my xml for this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RelativeLayout
android:id="#+id/first_relativelayout"
android:clickable="true"
android:background="#drawable/radio_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<TextView
android:id="#+id/first_textview"
android:text="#string/first_radiobutton_label"
android:textAppearance="?android:attr/textAppearanceButton"
android:textColor="#android:color/white"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<ImageView
android:contentDescription="#string/image_description"
android:id="#+id/first_imageview"
android:layout_centerVertical="true"
android:src="#drawable/it"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/first_textview">
</ImageView>
</RelativeLayout>
<RelativeLayout
android:id="#+id/second_relativelayout"
android:clickable="true"
android:background="#drawable/radio_button"
android:layout_weight="1"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<TextView
android:id="#+id/second_textview"
android:text="#string/second_radiobutton_label"
android:textAppearance="?android:attr/textAppearanceButton"
android:textColor="#android:color/white"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<ImageView
android:contentDescription="#string/image_description"
android:id="#+id/second_imageview"
android:layout_centerVertical="true"
android:src="#drawable/it"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/second_textview">
</ImageView>
</RelativeLayout>
</LinearLayout>
I kept going with the RelativeLayout solution. It takes more work than it seems should be worth it, but it works perfectly.
