I'd like to use a RadioGroup with RadioButton in a Dialog. I can have few RadioButton & I can have a lot of them, that's why I wrapped RadioGroup in a ScrollView. My layout looks like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tv_title_settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/btn_cancel"
android:layout_below="#+id/tv_title_settings">
<RadioGroup
android:id="#+id/radio_options_settings"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</ScrollView>
<Button
android:id="#+id/btn_cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
For the case with a lot of views I get:
The problem is with few elements:
I want it to ignore this empty space. I was trying with LinearLayout but the items overlap my button. Is there a workaround for this?
P.S. I can put RadioButton elements in a RecycleView but I have to restart it every time user selects a new RadioButton to achieve RadioGroup property - so I refused this idea.

in the below xml layout, i have two buttons at the same position and they will do their function based on the visibilty set. now i tried to place two textviews
below the buttons, i want the text views to be below both buttons so I used
android:layout_below="#id/actConnect2_btn_connect"
but at run time when the connect-button is visible the text view appears below it, and if pair-button is visible it overlap
how to display the textview below both buttons?
Note: i know that i can use android:layout:marginTop but i want to solve it without it
code:
<Button
android:id="#+id/actConnect2_btn_pair"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/actConnect2_tv_label_devClass"
android:layout_centerInParent="true"
android:text="#string/str_pair"/>
<Button
android:id="#+id/actConnect2_btn_connect"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/str_connect"
android:layout_below="#+id/actConnect2_tv_label_devClass"
android:layout_alignParentStart="true" />
<TextView
android:id="#+id/actConnect2_tv_label_uuids"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/actConnect2_btn_connect"
android:text="Service's UUID: ">
</TextView>
<TextView
android:id="#+id/actConnect2_tv_uuids"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/actConnect2_tv_label_uuids">
</TextView>
Put both buttons in a LinearLayout then put the textview below the LinearLayout
take both button in one layout
<RelativeLayout android:id="#+id/relativeButton"
android:layout_width="wrap_content"
android:layout_below="#id/actConnect2_tv_label_devClass"
android:layout_height="wrap_content">
<Button
android:id="#+id/actConnect2_btn_pair"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/str_pair"/>
<Button
android:id="#+id/actConnect2_btn_connect"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/str_connect"
android:layout_alignParentStart="true" />
</RelativeLayout>
and use this for your textview
android:layout_below="#id/relativeButton"
You have to place the buttons in a Layout (any type and arrange them accordingly)
Assign an ID to that layout.
Place the textView below that layout ID.
I am just starting to develop android apps. I have a layout question. I want to create the main screen for my app. It is a menu with 7 options, each options would be an icon at the left, a short text and a check at the left (on/off component).
I have written it in a list view element, I have created a simple adapter with this 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" >
<ImageView android:id="#+id/icon"
android:layout_width="?android:attr/listPreferredItemHeight"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:src="#drawable/ic_action_io"/>
<TextView android:id="#+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/icon"
android:layout_alignParentTop="true"
android:textAppearance="?android:attr/textAppearanceLarge"
android:singleLine="true" />
</RelativeLayout>
Menu will have always 7 options, I would like that the listview filled the height of the screen. Each element with the same height. Is it possible that with listview? Or, perhaps would be better making the menu out of a list view?
I have been reading about linear layout and the weight property. Please, could you help me? It is my first layout, I would thank any advice aboput layout I should use.
Thanks a lot, best regards!
P.D: Sorry for my english.
I would use a Linearlayout and inside i put all the items to be displayed...
Something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<RelativeLayout android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<ImageView android:id="#+id/icon"
android:layout_width="?android:attr/listPreferredItemHeight"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:src="#drawable/ic_launcher"/>
<TextView android:id="#+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/icon"
android:layout_alignParentTop="true"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Texto"
android:singleLine="true" />
</RelativeLayout>
<RelativeLayout android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<ImageView android:id="#+id/icon"
android:layout_width="?android:attr/listPreferredItemHeight"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:src="#drawable/ic_launcher"/>
<TextView android:id="#+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/icon"
android:layout_alignParentTop="true"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Texto"
android:singleLine="true" />
</RelativeLayout>
<!-- Repeat the item five times more -->
</LinearLayout>
if you want all the items to be displayed (without a scroll) then there's no use in a ListView. use a LinearLayout instead and set the layout_weight of each menu item to 1.
As the others guys said is better use the LinearLayout. And like you mentioned you can use weight attribute too.
Equally weighted children
To create a linear layout in which each child uses the same amount of space on the screen, set the android:layout_height of each view to "0dp" (for a vertical layout) or the android:layout_width of each view to "0dp" (for a horizontal layout). Then set the android:layout_weight of each view to "1".
As you are trying to implement a Menu, I think the best approach is substitute each RelativeLayout(with textview and imageview) for a button. So, your layout will be like that:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="7.0" > //Defines the maximum weight sum
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:height="0dp"
android:layout_weight="1"
android:text="Option 1"
android:drawableLeft="#drawable/icon1"
android:onClick="handleOption"/> // method to handle onClick
<Button
android:id="#+id/button2"
android:layout_width="match_parent"
android:height="0dp"
android:layout_weight="1"
android:text="Option 2"
android:drawableLeft="#drawable/icon2"
android:onClick="handleOption"/> // method to handle onClick
//Add more five buttons
.
.
.
In your activity, you should load this layout, using setContentView() and you must implement a method handleOption like below to handle onClick event of each button.
public view handleOption(View view)
{
switch(view.getId()) ....
}
In that way, you do not need implement onClickListener Interface, have one method to each button and set the onClickListener for each button.
In a layout resource XML, I have 3 RelativeLayout(s) which are inside a main RelativeLayout. The view will be shown vertically. These 3 RelativeLayout() are set next to each other, and I want them to fill the whole screen, doesnt matter what will be the screen size. My, layout view:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/backg"
>
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="#dimen/top_mr_image"
android:src="#drawable/temp" />
<RelativeLayout
android:id="#+id/r1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_below="#+id/imageView1"
android:layout_marginLeft="10dp"
android:background="#drawable/r1bg"
android:layout_weight="1"
>
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="#dimen/txt_mr_right"
android:layout_marginRight="#dimen/txt_mr_right"
android:layout_marginTop="39dp"
android:text="S"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#id/textView1"
android:layout_marginLeft="#dimen/txt_mr_right"
android:layout_marginRight="#dimen/txt_mr_right"
android:text="T"
android:textAppearance="?android:attr/textAppearanceLarge" />
</RelativeLayout>
<RelativeLayout
android:id="#+id/r2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignTop="#+id/r1"
android:layout_toRightOf="#+id/r1"
android:layout_weight="1" >
</RelativeLayout>
<RelativeLayout
android:id="#+id/r3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignTop="#+id/r2"
android:layout_toRightOf="#+id/r2"
android:layout_weight="1" >
</RelativeLayout>
I set weight=1 and layout_width=0dp for each relativeLayout and this technique works with buttons, I thought the same will be with relativeLayout, seems my thoughts were wrong. Any idea?
UPD1: I have added an image of what I would like to have
RelativeLayout does not pay attention to android:layout_weight. (That's a property of LinearLayout.LayoutParams, but not of RelativeLayout.LayoutParams.)
You should be able to get the layout you want with a much simpler view hierarchy. It's not clear what you are trying to do, since the last two RelativeLayouts are empty. If you need a purely vertical organization, I'd suggest using LinearLayout instead of RelativeLayout.
EDIT Based on your edit, it looks like you want a horizontal layout of three compound views, each one clickable. I think something like the following will work:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<!-- First column -->
<LinearLayout
android:id="#+id/firstColumn"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="..." />
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="text 1"
. . . />
</LinearLayout>
<!-- Second column -->
<LinearLayout . . . >
. . .
</LinearLayout>
</LinearLayout>
If the contents of the buttons aren't correct, you can replace the second-level LinearLayout views with RelativeLayout if that helps organize the layout better.
RelativeLayouts do not support weight. You need to use a LinearLayout as a parent container if you want to use weights.
Solution is very simple. I have been looking for weight distribution in relative layout.
It's a small trick for all these kind situations.
Use LinearLayout with android:orientation="horizontal"
You can use Horizontally oriented LinearLayout Manager in the Recycler View, and place each RelativeLayout in each item, of its Adapter.
The Link: How to build a Horizontal ListView with RecyclerView?
If your RelativeLayouts are set to a fixed width and height, that is to the size of the Screen, that you can get from DisplayMatrics, that will be OK.
The Link: Get Screen width and height
If the contents of your RelativeLayouts are different, then you can use getItemViewType() method.
Please see: How to create RecyclerView with multiple view type?
Happy Coding :-)
I'd like to recreate the CheckedTextView's functionality using my own custom views so I can have two TextViews on the left with a CheckBox on the right, centered vertically between the two TextViews. I have the Layout working for it, which I will include below. I also have it so that when you click on the outer LinearLayout (LinearLayout1) it will pass that click to the checkbox. The only thing that I can't figure out is when you press down on a checkbox it briefly highlights the checkbox (in yellow on my device) before marking it checked. I'd like to have it do the same if you touch anywhere on the outer LinearLayout, but I don't know where I'd need to hook in to make that happen.
Here is my layout.xml
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/LinearLayout1">
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content"
android:layout_width="0dip"
android:layout_weight="1"
android:id="#+id/LinearLayout2">
<TextView
android:id="#+id/FieldValueTextView"
android:text="Value"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/FieldLabelTextView"
android:text="Label"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall" />
</LinearLayout>
<CheckBox
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_toRightOf="#id/LinearLayout2"
android:id="#+id/CheckBox"
android:gravity="center_vertical" />
</LinearLayout>
Thanks,
Dan
The problem I was experiencing was solved by putting the following android:focusable="false" on the CheckBox and the two TextViews so that when the ListView is clicked, it gets the focus, not the inner views.
Hope that helps someone else.
How do I design an android application with two buttons next to each other (horizontal) and below these buttons i have a textview (vertical) using LinearLayout? Can't get it to work.
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:orientation="horizontal">
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" />
Far better to use the RelativeLayout in this case. You just described your desired result in terms of the items of your view relative to one another. It is simpler to use than you might think.
