I'm making an easy chatting app and I made a .9.png pic as the speech bubble. Here's a part of the message item layout XML (the bubble sent by user):
<LinearLayout
android:id="#+id/right_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:background="#drawable/bg_send">
<TextView
android:id="#+id/right_msg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="10dp"
android:textColor="#color/abc_primary_text_material_dark"/>
</LinearLayout>
The #drawable/bg_send is a 102px*102px .9.png file at app\res\. I thought it should be small displaying on my 5" 1920*1080 phone. But it's bigger than it should be and that caused blurring.
What should I do if I want to make it as I wish?
Instead of using .9.png use the drawable images instead. Here is the xml code that will fulfill your requirement.
res/drawable/bg_textview.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#607D8B"/>
<corners android:radius="30dp"/>
</shape>
The image stretches to the size of of your LinearLayout (for which it is the background). The margin around the TextView makes the LinearLayout bigger. Move the android:layout_margin="10dp" attribute to the LinearLayout to have a margin around the bubble.
Try this one
<LinearLayout
android:id="#+id/right_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
>
<TextView
android:id="#+id/right_msg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="10dp"
android:background="#drawable/bg_send"
android:textColor="#color/abc_primary_text_material_dark"/>
Good luck
I'm trying to my custom RadioButton that I trying to make to look like this:
So I did custom drawables that respond to the RadioButton status and used it as background. This is alright.
The problem is that I'm not been able to center the images that I set through the android:button atribute.
Here is how I'm trying to use it in my layout.
<RadioGroup
android:id="#+id/presenter_options"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="4dp"
android:gravity="center"
>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="#drawable/cluster_centered"
android:gravity="center"
android:padding="8dp"
android:background="#drawable/presenter_radiobutton_left"
/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="8dp"
android:background="#drawable/presenter_radiobutton_right"
android:button="#drawable/fire"
/>
</RadioGroup>
With this I'm getting this as result:
I've already tried to define a drawable that sets the gravity to center, but nothing changed. Here is the custom drawable:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<bitmap android:src="#drawable/cluster" android:gravity="center"/>
</item>
</selector>
So, how could I center the button images?
PS: I can't set each kind of button as background because it'll be dynamic in the future, so the only thing that could be in background is the blue shape.
My solution was to set android:button=#null, then set the image that I want into the android:drawableLeft attribute. So my RadioButton code is like this:
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="8dp"
android:background="#drawable/presenter_radiobutton_left"
android:button="#null"
android:drawableLeft="#drawable/fire"
/>
"on center" solution is
...
<RadioButton>
...
android:button="#null"
android:foreground="#drawable/your_selector_for_center_drawable"
android:background="#drawable/your_selector_for_background_drawable"
android:foregroundGravity="center"
This happens very frequently to me when starting to work on android. The text within the button element is not showing fully. What can be wrong? I tried text direction, alignment, gravity but nothing works.
The code behind it:
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/textView1"
android:layout_centerHorizontal="true"
android:layout_marginTop="40dp"
android:text="#string/latestButtonString"
android:background="#drawable/roundbutton" />
Please help and much appreciated.
Update: This is the roundbutton.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<!-- you can use any color you want I used here gray color-->
<solid android:color="#ABABAB"/>
<corners
android:bottomRightRadius="10dp"
android:bottomLeftRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>
</shape>
I had this problem, I solved it by chaning the xml for the button from using tools: to android: for the text attribute. Example below (last line is the line thats changed):
<Button
android:id="#+id/btn_settings"
style="#style/Widget.AppCompat.Button.Borderless"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textColor="#F6F6F6"
tools:text="App Settings" />
becomes...
<Button
android:id="#+id/btn_settings"
style="#style/Widget.AppCompat.Button.Borderless"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textColor="#F6F6F6"
android:text="App Settings" />
try to replace
android:text="#string/latestButtonString"
and put direct hardcode string here
as,
android:text="hello"
or
try to replace this line in roundbutton.xml:
<android:shape="rectangle" android:padding="10dp">
with
<android:shape="rectangle" android:padding="3dp">
Can you please check by removing android:background="#drawable/roundbutton" from your button attribute. If text shown fully, then you need to modify the #drawable/roundbutton" there may be you have set fixed width thus your text in button is not fully visible.
It seems that you have a paddingLeft on your Button. Can you check if this is present in your styles.xml?
If it is in your styles.xml, it is probably important for the theme of your app.
If you would just want to cancel it in that certain Button, just put
android:paddingLeft="0dp"
Faced a similar problem...following attribute made it work:
android:layout_weight="1"
please remove these line android:background="#drawable/roundbutton" but view not create like you if you want to create same view please try these code :
code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<LinearLayout
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_marginTop="40dp"
android:padding="20dp"
android:background="#drawable/roundbutton">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="latestButtonString"
android:textColor="#000000"
android:textSize="18sp"/>
</LinearLayout>
I have a TextView and I want to add a bullet symbol in my text through XML. Is it possible?
You have to use the right character encoding to accomplish this effect. You could try with •
Update
Just to clarify: use `setText("\u2022 Bullet");` to add the bullet programmatically. `0x2022 = 8226`
This worked for me:
<string name="text_with_bullet">Text with a \u2022</string>
Copy paste: •. I've done it with other weird characters, such as ◄ and ►.
Edit: here's an example. The two Buttons at the bottom have android:text="◄" and "►".
Prolly a better solution out there somewhere, but this is what I did.
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<TableRow>
<TextView
android:layout_column="1"
android:text="•"></TextView>
<TextView
android:layout_column="2"
android:layout_width="wrap_content"
android:text="First line"></TextView>
</TableRow>
<TableRow>
<TextView
android:layout_column="1"
android:text="•"></TextView>
<TextView
android:layout_column="2"
android:layout_width="wrap_content"
android:text="Second line"></TextView>
</TableRow>
</TableLayout>
It works like you want, but a workaround really.
You may try BulletSpan as described in Android docs.
SpannableString string = new SpannableString("Text with\nBullet point");
string.setSpan(new BulletSpan(40, color, 20), 10, 22, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Another best way to add bullet in any text view is stated below two steps:
First, create a drawable
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<!--set color of the bullet-->
<solid
android:color="#666666"/> //set color of bullet
<!--set size of the bullet-->
<size
android:width="120dp"
android:height="120dp"/>
</shape>
Then add this drawable in textview and set its pedding by using below properties
android:drawableStart="#drawable/bullet"
android:drawablePadding="10dp"
This is how i ended up doing it.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<View
android:layout_width="20dp"
android:layout_height="20dp"
android:background="#drawable/circle"
android:drawableStart="#drawable/ic_bullet_point" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="Your text"
android:textColor="#000000"
android:textSize="14sp" />
</LinearLayout>
and the code for drawbale/circle.xml is
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="ring"
android:thickness="5dp"
android:useLevel="false">
<solid android:color="#color/black1" />
</shape>
With Unicode we can do it easily, but if want to change color of bullet, I tried with colored bullet image and set it as drawableStart and it worked
<TextView
android:text="Hello bullet"
android:drawableStart="#drawable/bulleticon" >
</TextView>
Since android doesnt support <ol>, <ul> or <li> html elements, I had to do it like this
<string name="names"><![CDATA[<p><h2>List of Names:</h2></p><p>•name1<br />•name2<br /></p>]]></string>
if you want to maintain custom space then use </pre> tag
(almost) all of the options are about using html tags.
you can use drawables for your TextView if it has only one line of text.
something like this:
<TextView
android:id="#+id/tv_with_bullet"
android:layout_width="match_parent"
android:layout_height="50dp"
app:drawableStartCompat="#drawable/ic_desired_bullet_icon" />
and add your desired bullet drawable in SVG. it literally takes no space and makes you free of adding complicated string literals. you can also download the SVG file for a bullet point in here
I'm trying to have an image (as the background) on a button and add dynamically, depending on what's happening during run-time, some text above/over the image.
If I use ImageButton I don't even have the possibility to add text.
If I use Button I can add text but only define an image with android:drawableBottom and similar XML attributes as defined here.
However these attributes only combine text & image in x- and y-dimensions, meaning I can draw an image around my text, but not below/under my text (with the z-axis defined as coming out of the display).
Any suggestions on how to do this? One idea would be to either extend Button or ImageButton and override the draw()-method. But with my current level of knowledge I don't really know how to do this (2D rendering). Maybe someone with more experience knows a solution or at least some pointers to start?
For users who just want to put Background, Icon-Image and Text in one Button from different files: Set on a Button background, drawableTop/Bottom/Rigth/Left and padding attributes.
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/home_btn_test"
android:drawableTop="#drawable/home_icon_test"
android:textColor="#FFFFFF"
android:id="#+id/ButtonTest"
android:paddingTop="32sp"
android:drawablePadding="-15sp"
android:text="this is text"></Button>
For more sophisticated arrangement you also can use RelativeLayout (or any other layout) and make it clickable.
Tutorial: Great tutorial that covers both cases: http://izvornikod.com/Blog/tabid/82/EntryId/8/Creating-Android-button-with-image-and-text-using-relative-layout.aspx
There's a much better solution for this problem.
Just take a normal Button and use the drawableLeft and the gravity attributes.
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/my_btn_icon"
android:gravity="left|center_vertical" />
This way you get a button which displays a icon in the left side of the button and the text at the right site of the icon vertical centered.
You can call setBackground() on a Button to set the background of the button.
Any text will appear above the background.
If you are looking for something similar in xml there is:
android:background attribute which works the same way.
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:background="#drawable/home_button"
android:drawableLeft="#android:drawable/ic_menu_edit"
android:drawablePadding="6dp"
android:gravity="left|center"
android:height="60dp"
android:padding="6dp"
android:text="AndroidDhina"
android:textColor="#000"
android:textStyle="bold" />
Just use a LinearLayout and pretend it's a Button - setting background and clickable is the key:
<LinearLayout
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:drawable/btn_default"
android:clickable="true"
android:orientation="horizontal" >
<ImageView
android:id="#+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:src="#drawable/image" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_margin="5dp"
android:text="Do stuff" />
</LinearLayout>
just replace
android:background="#drawable/icon"
with
android:background="#android:color/transparent"
android:drawableTop="#drawable/[your background image here]"
izz a pretty good trick.. ;)
I took a different approach from the ones stated here, and it is working really well, so I wanted to share it.
I'm using a Style to create a custom button with image at the left and text at the center-right. Just follow the 4 "easy steps" below:
I. Create your 9 patches using at least 3 different PNG files and the tool you have at: /YOUR_OWN_PATH/android-sdk-mac_x86/tools/./draw9patch. After this you should have:
button_normal.9.png, button_focused.9.png and button_pressed.9.png
Then download or create a 24x24 PNG icon.
ic_your_icon.png
Save all in the drawable/ folder on your Android project.
II. Create a XML file called button_selector.xml in your project under the drawable/ folder. The states should be like this:
<item android:state_pressed="true" android:drawable="#drawable/button_pressed" />
<item android:state_focused="true" android:drawable="#drawable/button_focused" />
<item android:drawable="#drawable/button_normal" />
III. Go to the values/ folder and open or create the styles.xml file and create the following XML code:
<style name="ButtonNormalText" parent="#android:style/Widget.Button">
<item name="android:textColor" >#color/black</item>
<item name="android:textSize" >12dip</item>
<item name="android:textStyle" >bold</item>
<item name="android:height" >44dip</item>
<item name="android:background" >#drawable/button_selector</item>
<item name="android:focusable" >true</item>
<item name="android:clickable" >true</item>
</style>
<style name="ButtonNormalTextWithIcon" parent="ButtonNormalText">
<item name="android:drawableLeft" >#drawable/ic_your_icon</item>
</style>
ButtonNormalTextWithIcon is a "child style" because it is extending ButtonNormalText (the "parent style").
Note that changing the drawableLeft in the ButtonNormalTextWithIcon style, to drawableRight, drawableTop or drawableBottom you can place the icon in other position with respect to the text.
IV. Go to the layout/ folder where you have your XML for the UI and go to the Button where you want to apply the style and make it look like this:
<Button android:id="#+id/buttonSubmit"
android:text="#string/button_submit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="#style/ButtonNormalTextWithIcon" ></Button>
And... voilà! You got your button with an image at the left side.
For me, this is the better way to do it! because doing it this way you can manage the text size of the button separately from the icon you want to display and use the same background drawable for several buttons with different icons respecting the Android UI Guidelines using styles.
You can also create a theme for your App and add the "parent style" to it so all the buttons look the same, and apply the "child style" with the icon only where you need it.
Important Update
Don't use normal android:drawableLeft etc... with vector drawables, else it
will crash in lower API versions. (I have faced it in live app)
For vector drawable
If you are using vector drawable, then you must
Have you migrated to AndroidX? if not you must migrate to AndroidX first. It is very simple, see what is androidx, and how to migrate?
It was released in version 1.1.0-alpha01, so appcompat version should be at least 1.1.0-alpha01. Current latest version is 1.1.0-alpha02, use latest versions for better reliability, see release notes - link.
implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
Use AppCompatTextView/AppCompatButton/AppCompatEditText
Use app:drawableLeftCompat, app:drawableTopCompat, app:drawableRightCompat, app:drawableBottomCompat, app:drawableStartCompat and app:drawableEndCompat
For regular drawable
If you don't need vector drawable, then you can
use android:drawableLeft, android:drawableRight, android:drawableBottom, android:drawableTop
You can use either regular TextView, Button & EditText or AppCompat classes.
You can achieve Output like below -
<Button android:id="#+id/imeageTextBtn"
android:layout_width="240dip"
android:layout_height="wrap_content"
android:text="Side Icon With Text Button"
android:textSize="20sp"
android:drawableLeft="#drawable/left_side_icon"
/>
You can use drawableTop (also drawableLeft, etc) for the image and set text below the image by adding the gravity left|center_vertical
<Button
android:id="#+id/btn_video"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:background="#null"
android:drawableTop="#drawable/videos"
android:gravity="left|center_vertical"
android:onClick="onClickFragment"
android:text="Videos"
android:textColor="#color/white" />
MaterialButton has support for setting an icon and aligning it to the text:
<com.google.android.material.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My button"
app:icon="#drawable/your_icon"
app:iconGravity="textStart"
/>
app:iconGravity can also be to start / end if you want to align the icon to the button instead of the text inside it.
Since version 1.5.0-beta01, app:iconGravity can also be top / textTop (commit)
<Button
android:id="#+id/groups_button_bg"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Groups"
android:drawableTop="#drawable/[image]" />
android:drawableLeft
android:drawableRight
android:drawableBottom
android:drawableTop

Probably my solution will suit for a lot of users, I hope so.
What I am suggesting it is making TextView with your style. It works for me perfectly, and has got all features, like a button.
First of all lets make button style, which you can use everywhere...I am creating button_with_hover.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#8dbab3" />
<gradient android:angle="-90" android:startColor="#48608F" android:endColor="#48608F" />
</shape>
<!--#284682;-->
<!--border-color: #223b6f;-->
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#284682" />
<solid android:color="#284682"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#color/ControlColors" />
<gradient android:angle="-90" android:startColor="#color/ControlColors" android:endColor="#color/ControlColors" />
</shape>
</item>
</selector>
Secondly,
Lets create a textview button.
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="20dip"
android:layout_gravity="right|bottom"
android:gravity="center"
android:padding="12dip"
android:background="#drawable/button_with_hover"
android:clickable="true"
android:drawableLeft="#android:drawable/btn_star_big_off"
android:textColor="#ffffffff"
android:text="Golden Gate" />
And this is a result. Then style your custom button with any colors or any other properties and margins. Good luck
This code works for me perfectly
<LinearLayout
android:id="#+id/choosePhotosView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center"
android:clickable="true"
android:background="#drawable/transparent_button_bg_rev_selector">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/choose_photo"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:text="#string/choose_photos_tv"/>
</LinearLayout>
To combine Button and drawableTop and still get the click response, you can use button style #style/Widget.AppCompat.Button.Borderless to make it transparent.
<Button
android:id="#+id/settings"
style="#style/Widget.AppCompat.Button.Borderless"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="#drawable/ic_baseline_settings_24"
android:drawableTint="?attr/colorPrimary"
android:text="#string/settings"
android:textColor="?attr/colorPrimary" />
<Button android:id="#+id/myButton"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:text="Image Button"
android:drawableTop="#drawable/myimage"
/>
Or you can programmatically:
Drawable drawable = getResources.getDrawable(R.drawable.myimage);
drawable.setBounds(0, 0, 60, 60);
myButton.setCompoundDrawables(null, drawable, null, null);//to the Top of the Button
You can use this:
<Button
android:id="#+id/reset_all"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dp"
android:layout_weight="1"
android:background="#drawable/btn_med"
android:text="Reset all"
android:textColor="#ffffff" />
<Button
android:id="#+id/undo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_weight="1"
android:background="#drawable/btn_med"
android:text="Undo"
android:textColor="#ffffff" />
in that i have put an image as background and also added text..!
Make a fake button.
It's really the only way
<FrameLayout
android:id="#+id/fake_button"
android:layout_width=" .. "
android:layout_height=" .. "
android:background="#android:color/transparent"
android:clickable="true"
android:onClick="tappedNext">
<ImageView
android:id="#+id/fake_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/your_amazing_drawable" />
<TextView
android:id="#+id/fake_text"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="Next"
android:fontFamily="#font/ .. "
android:textColor="#color/ .. "
android:textSize=" .. " />
</FrameLayout>
<ImageView
android:id="#+id/iv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:src="#drawable/temp"
/>
