How do I add a bullet symbol in TextView?
I have a TextView and I want to add a bullet symbol开发者_开发知识库 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 Button
s 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
