How to add bulleted list to android application?

Question

I have googled my question but there is not working answer provided. How do add a bulleted list to my textview.

Answer 1

The two options you have for doing a bulleted list are

• create the list using html (ul,ol) and load the html into a WebView
• Load the data into a ListView and set the left drawable of your text view in the list item layout, to a suitable image for the bullet.

Option 1 is the easiest.

Answer 2

If You want to create bullet list with editText structure.

I benefited this references

You can use this bullets

           EditText  edtNoteContent = findViewById(R.id.editText_description_note);            

        edtNoteContent.addTextChangedListener(new TextWatcher(){
            @Override
            public void afterTextChanged(Editable e) {

            }
            @Override
            public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {

            }
            @Override
            public void onTextChanged(CharSequence text, int start, int lengthBefore, int lengthAfter)
            {
                if (lengthAfter > lengthBefore) {
                    if (text.toString().length() == 1) {
                        text = "◎ " + text;
                        edtNoteContent.setText(text);
                        edtNoteContent.setSelection(edtNoteContent.getText().length());
                    }
                    if (text.toString().endsWith("\n")) {
                        text = text.toString().replace("\n", "\n◎ ");
                        text = text.toString().replace("◎ ◎", "◎");
                        edtNoteContent.setText(text);
                        edtNoteContent.setSelection(edtNoteContent.getText().length());
                    }
                }
            }
        });

Answer 3

use simple TextView with a compound drawable. For example

<TextView     
    android:text="Sample text"
    android:drawableLeft="@drawable/bulletimage" >
</TextView>

Answer 4

Went completely overkill and made a custom text view.

Use it like this:

<com.blundell.BulletTextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="--bullet 1 --bullet two --bullet three --bullet four" />

and the code:

package com.blundell;

import android.content.Context;
import android.text.Html;
import android.util.AttributeSet;
import android.widget.TextView;

public class BulletTextView extends TextView {
    private static final String SPLITTER_CHAR = "--";
    private static final String NEWLINE_CHAR = "<br/>";
    private static final String HTML_BULLETPOINT = "&#8226;";

    public BulletTextView(Context context, AttributeSet attrs) {
        this(context, attrs, android.R.attr.textViewStyle);
    }

    public BulletTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        checkForBulletPointSplitter();
    }

    private void checkForBulletPointSplitter() {
        String text = (String) getText();
        if (text.contains(SPLITTER_CHAR)) {
            injectBulletPoints(text);
        }
    }

    private void injectBulletPoints(String text) {
        String newLinedText = addNewLinesBetweenBullets(text);
        String htmlBulletText = addBulletPoints(newLinedText);
        setText(Html.fromHtml(htmlBulletText));
    }

    private String addNewLinesBetweenBullets(String text) {
        String newLinedText = text.replace(SPLITTER_CHAR, NEWLINE_CHAR + SPLITTER_CHAR);
        newLinedText = newLinedText.replaceFirst(NEWLINE_CHAR, "");
        return newLinedText;
    }

    private String addBulletPoints(String newLinedText) {
        return newLinedText.replace(SPLITTER_CHAR, HTML_BULLETPOINT);
    }

}

Answer 5

For single line text you can simply use drawables:

<TextView
    android:id="@+id/txtData"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawableStart="@drawable/draw_bullet_list"
    android:drawablePadding="@dimen/padding_8dp"
    android:text="Hello"
    android:textColor="@color/colorBlack" />

draw_bullet_list.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="@color/colorAccent" />

    <size
        android:width="12dp"
        android:height="12dp" />

</shape>

You can change shape, size,color based on your requirement.
