I'm trying to put three items in horizontal align using this code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:layout_gravity="right"
android:layout_marginTop="10dp"
android:orientation="horizontal">
<ImageView
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginLeft="10dp"
android:src="#drawable/address"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:text="#string/lbl_address"/>
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:id="#+id/txtAddress" />
</LinearLayout>
The problem is gravity never worked, the ImageView always starts from the left and other items follows in the same order.
I have tried to reverse item orders in the code which will work on none RTL languages, but my application targets both, so it shows wrong on RTL supported devices.
Also I have tried RelativeLayout but items come over each other.
Note: All languages should start from right to left, this is my desired behavior
Add this attribute to your root LinearLayout tag:
android:layoutDirection="rtl"
This will make your view lay out as though the user had chosen a right-to-left language, regardless of what language they've actually chosen.
Try to use this code in AndroidManifest.xml
android:supportsRtl="true"
For support languages that start from right in app.
Because you use android:layout_width="0dp" android:layout_weight="1" in your code .The TextView will use the rest of space .So the left image will on the left .So you can remove android:layout_weight="1" and change the width of TextView .
You can change
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:id="#+id/txtAddress" />
to
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:id="#+id/txtAddress" />
Note
If you want to change the location of the LinearLayout's item .You can use android:gravity="right" .
If you want to change the location of the LinearLayout ,you can use android:layout_gravity="right" .
And you code is android:layout_width="match_parent" , so the android:layout_gravity="right" has no effect .
And you can use android:layoutDirection="rtl" in your LinearLayout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:layout_gravity="right"
android:layout_marginTop="10dp"
android:orientation="horizontal"
android:layoutDirection="rtl"

I'm trying to have two TextViews side-by-side, and I want one to be touching the right-side of the screen and the other, the left-side. I don't want to define the widths using numbers because screens of different sizes would behave differently. So I'm trying to use layout_gravity, which is not working for some reason.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16dp"
android:layout_gravity="left"
android:text="rrr"
android:textColor="#color/secondTextColor"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:textSize="16dp"
android:text="sss"
android:textColor="#color/secondTextColor" />
</LinearLayout>
Can anyone tell me why? Thanks!
You can create one LinearLayout for each TextView as follows :
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="start">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16dp"
android:text="rrr"
android:textColor="#f2f2"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="end">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16dp"
android:text="sss"
android:textColor="#f3f3" />
</LinearLayout>
</LinearLayout>
And the important thing is that in your first LinearLayout you put android:gravity="start" and in your second one android:gravity="end", then it will work :)
Use end instead of right to ensure correct behavior in right-to-left locales.
Why is "end" better than "right"?
Using Gravity#LEFT and Gravity#RIGHT can lead to problems when a layout is rendered in locales where text flows from right to left.
Use Gravity#START and Gravity#END instead. Similarly, in XML gravity and layout_gravity attributes, use start rather than left.
For XML attributes such as paddingLeft and layout_marginLeft, use paddingStart and layout_marginStart.
NOTE: If your minSdkVersion is less than 17, you should add both the older left/right attributes as well as the new start/right attributes. On older platforms, where RTL is not supported and the start/right attributes are unknown and therefore ignored, you need the older left/right attributes. There is a separate lint check which catches that type of error.
(Note: For Gravity#LEFT and Gravity#START, you can use these constants even when targeting older platforms, because the start bitmask is a superset of the left bitmask. Therefore, you can use gravity="start" rather than gravity="left|start".)
You can try with android:layout_weight & android:gravity .
Read What does android:layout_weight mean & Layout Weight
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:weightSum="1" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:gravity="left"
android:text="Intellij" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:gravity="right" // You can add end instead of right
android:text="Amiya" />
</LinearLayout>
You could use android:layout_weight="1" on TextView's and 0dp for width.
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'm trying to set my TextView to the left of an ImageButton, but I can't seems to find this option.
I was expecting to use something like android:layout_alignLeft, but this option is missing.
I've tried to google the issue, but couldn't find any relative results.
Without it my TextView overlaps the ImageButton and I want to avoid it.
UPDATE
The full xml code is too complex, but here is the important part of it:
<FrameLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentLeft="true"
android:background="#color/white"
android:layout_marginLeft="8dp"
android:layout_marginTop="8dp"
android:layout_marginBottom="8dp"
android:layout_toLeftOf="#+id/frameLayoutBalanceClosed">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/button_edit_nickname"
android:id="#+id/card_closed_control_editNickname" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/card_closed_description_nickname"
android:layout_margin="8dp" android:layout_gravity="left"/>
</FrameLayout>
I think what you need is a RelativeLayout. You can specify your TextView to the left of your ImageView with it's specifications. Your code would look something like this:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/imagebutton1" />
<ImageButton
android:id="#+id/imagebutton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
The reason FrameLayout isn't working is because it's purpose is to overlay items on top of each other, which wouldn't work at all!
If that isn't what you're looking for, you could also use a TableLayout in which items are arranged in columns.
I have an EditText and a Button in my LinearLayout and I want to align them closely together so they see seem to belong together (edittext + micButton for speech input).
Now they don't have the same height and they aren't really aligned well (Button seems to be a little lower than the EditText). I know I can apply a negative margin like -5dp to make them come closer together, but is there perhaps a better way to do this?
Set them in a specific container/layout so that they will automatically have the same height and no margin between them?
Using relative layout you can stretch a view depending upon another views size without knowing the exact size of the other view.
Here is the code :
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<Button
android:layout_width="100dp"
android:layout_height="100dp"
android:text="button"
android:id="#+id/but"/>
<EditText
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/but"
android:layout_alignBottom="#id/but"
android:layout_alignTop="#id/but"
/>
</RelativeLayout>
Check this link for reducing space between views :
https://groups.google.com/forum/?fromgroups#!topic/android-developers/RNfAxbqbTIk
Hmm, don't know why people bother so much with tables. Since the both Views are within a LinearLayout (presumable orientation=Horizontal), this command should center both within the layout:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
Note: Since EditTexts and Buttons may orient their text slightly differently, you may have to do some tweaking (by changing margins or padding) to get the text to align properly.
I hope this solution might help for your scenario...Here is the code..
<RelativeLayout
android:id="#+id/rlLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:orientation="horizontal"
android:padding="3dp" >
<EditText
android:id="#+id/etId"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#c8c8c8"
android:hint="Edittext"
android:paddingLeft="20dip"
android:paddingRight="10dip"
android:textColor="#000000" />
<RelativeLayout
android:id="#+id/rlLayoutid"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignRight="#+id/etId" >
<Button
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:layout_marginRight="14dp"
android:layout_marginTop="10dp"
android:background="#drawable/calender" />
</RelativeLayout>
</RelativeLayout>
# Daniel Here You can use layout weight and weight sum
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center"
android:weight_sum=2
>
<Button
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=1
android:text="button"
android:id="#+id/but"/>
<EditText
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=1
/>
</LinearLayout>
Android tries to automatically level everything off of the text and not the buttons themselves.
Took me forever to finally figure it out. Its really simple. Should fix it.
myButton.setGravity(Gravity.CENTER_VERTICAL);
or if they are in a row.. attach the buttons to a table row, then.
myTableRow.setGravity(Gravity.CENTER_VERTICAL);
When I run layout on a specific XML file, I get this:
This tag and its children can be replaced by one <TextView/>
and a compound drawable
What change should be done for the following xml code:
<LinearLayout android:id="#+id/name_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:background="#drawable/grouplist_single_left_grey_area" >
<ImageView android:id="#+id/photo_image"
android:layout_width="#dimen/thumbnail_width"
android:layout_height="#dimen/thumbnail_height"
android:paddingBottom="5dip"
android:paddingTop="5dip"
android:paddingRight="5dip"
android:paddingLeft="5dip"
android:layout_marginRight="5dip"
android:clickable="true"
android:focusable="true"
android:scaleType="fitCenter"
android:src="#*android:drawable/nopicture_thumbnail"
android:background="#drawable/photo_highlight" />
<TextView android:id="#+id/name"
android:paddingLeft="5dip"
android:layout_weight="1"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
This is how it looks like on the screen:
The camera icon is the default. Clicking on that will give the user an option to choose another image.
To expand on Romain Guy's answer, here is an example.
Before:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:padding="5dp" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="My Compound Button" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/my_drawable" />
</LinearLayout>
After:
<TextView
android:layout_marginTop="10dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My Compound Button"
android:drawableRight="#drawable/my_drawable" android:padding="5dp" />
Merge the TextView and the ImageView into one, by using TextView's setCompoundDrawable*() methods, or using android:drawableLeft.
Thought I would try to get some extra puntos for this as well: you can add padding between the image and the text using android:drawablePadding. https://stackoverflow.com/a/6671544/1224741
Add tools:ignore="UseCompoundDrawables" to <LinearLayout>.
Sometimes it is possible to replace ImageView (or multiple) and TextView with one TextView with compound drawable(s). There are NOT many parameters which can be applied to compound drawable using native API and this TextViewRichDrawable library, but if you can manage one TextView instead of using LinearLayout you should definitely use it.
The list of attributes and parameters which can be applied to compound drawables:
Size: (YES, really):
<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Some text"
app:compoundDrawableHeight="24dp"
app:compoundDrawableWidth="24dp"/>
Even set vector resource as drawable:
<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Some text"
app:drawableTopVector="#drawable/some_vector_drawble"
app:drawableEndVector="#drawable/another_vector_drawable" />
Drawable's Padding using native API android:drawablePadding -> link
Here is an example:
A LinearLayout which contains an ImageView and a TextView can
be more efficiently handled as a compound drawable (a single
TextView, using the drawableTop, drawableLeft, drawableRight
and/or drawableBottom attributes to draw one or more images
adjacent to the text).
If the two widgets are offset from each other with margins, this
can be replaced with a drawablePadding attribute.
There's a lint quickfix to perform this conversion in the Eclipse
plugin.
From: Android Official API docs!
When I followed the code above, text inside the TextView doesn't set properly.
You need to set its gravity to center|start to achieve what shown in the asked question.
The textview looks like this:
<TextView
android:id="#+id/export_text"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:drawableLeft="#drawable/up_arrow"
android:drawableStart="#drawable/up_arrow"
android:gravity="center|start"
android:text="....."
android:textSize="#dimen/font_size15" >
</TextView>
the latest correct way at time of writing to add a compound drawable is using app:drawableStartCompat rather than android:drawableLeft.
<TextView
android:layout_marginTop="10dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My Compound Button"
android:drawablePadding="5dp"
app:drawableStartCompat="#drawable/my_drawable" />
You can refer this code for example
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="#string/myName"
android:textAlignment="center"
android:textColor="#color/myColor"
app:drawableTopCompat="#drawable/image_name" />
If you don't want to change the ImageView and TextView, you can change the version in the AndroidManifest.xml as:
<uses-sdk`
android:minSdkVersion="8"
android:targetSdkVersion="18"
/>
If your version is android:targetSdkVersion="17" change it s "18".
Hope this will rectify. I did it and got it right
I don't know if this is an efficient solution. But using <androidx.appcompat.widget.LinearLayoutCompat> to wrap the imageView and TextView instead of <LinearLayout> will fix this error. Also by using LinearLayoutCompat, you will be able to adjust the image's width and height which you can't when using a drawableRight, drawableLeft, drawableTop or drawableBottom inside a TextView.
This warning is rather misleading. You can use a compound drawable using a TextView as others have suggested but it doesn't necessarily give you the desired result. You have very littler control over how you want your button to look like using a compound drawable, so it is better to just add tools:ignore="UseCompoundDrawables" and ignore this warning.
Another approach is embed the ViewImage into another LinearLayout (allow handle it with alone id):
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/blue_3"
android:layout_gravity="center_horizontal"
android:paddingTop="16dp" />
</LinearLayout>
<TextView
android:id="#+id/tvPrompt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:paddingTop="16dp"
android:text="#string/xy" />
This tag and its children can be replaced by one <TextView/> and a compound drawable
