How to take bold characters as input in EditText in Android?

Question

I am making a Note Making App which has a feature of adding Bold text via a button. When the bold button is clicked the bold mode should be turned on i.e the text taken from user in EditText should now be Bold. On the next Click on the bold button the bold mode should be turned off i.e text taken from the user should now be of Normal type.

I saw this post. Change future text to bold in EditText in Android But the answer in that post did not work out. When I first click the button it takes bold input but when I clicked the button again to take Normal text as input it was still taking bold text as input.

Here is the code: TextArea.java

package com.example.syed.andtexteditor;


import android.content.Context;
import android.graphics.Typeface;
import android.support.v7.widget.AppCompatEditText;
import android.text.Spannable;
import android.text.style.StyleSpan;
import android.util.AttributeSet;
import android.widget.EditText;


public class TextArea extends AppCompatEditText {

    public static final int TYPEFACE_NORMAL = 0;
    public static final int TYPEFACE_BOLD = 1;
    public static final int TYPEFACE_ITALICS = 2;
    public static final int TYPEFACE_BOLD_ITALICS = 3;

    private int currentTypeface;
    private int lastCursorPosition;
    private int tId;


    public TextArea(Context context) {
        super(context);
        lastCursorPosition = this.getSelectionStart();
    }

    public TextArea(Context context, AttributeSet attrs) {
        super(context, attrs);
    }


    public int gettId() {
        return tId;
    }

    public void settId(int tId) {
        this.tId = tId;
    }

    public void changeTypeface(int tfId) {
        currentTypeface = tfId;
        lastCursorPosition = this.getSelectionStart();
    }

    @Override
    protected void onTextChanged(CharSequence text, int start, int lengthBefore, int lengthAfter) {
        Spannable str = this.getText();
        StyleSpan ss;
        int endLength = text.toString().length();

        switch(currentTypeface) {
            case TYPEFACE_NORMAL:
                ss = new StyleSpan(Typeface.NORMAL);
                break;
            case TYPEFACE_BOLD:
                ss = new StyleSpan(Typeface.BOLD);
                break;
            case TYPEFACE_ITALICS:
                ss = new StyleSpan(Typeface.ITALIC);
                break;
            case TYPEFACE_BOLD_ITALICS:
                ss = new StyleSpan(Typeface.BOLD_ITALIC);
                break;
            default:
                ss = new StyleSpan(Typeface.NORMAL);
        }

        str.setSpan(ss, lastCursorPosition, endLength, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    }
}

MainActivity.java:

package com.example.syed.andtexteditor;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;

public class MainActivity extends AppCompatActivity {
    boolean boldClicked=false;
    int typefaceStyle = TextArea.TYPEFACE_NORMAL;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button boldButton = (Button)findViewById(R.id.bold_button);
        boldButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                TextArea t =  (TextArea) findViewById(R.id.textInput);
                if (!boldClicked)
                    boldClicked = true;
                else if (boldClicked)
                    boldClicked = false;
                if (boldClicked) {
                    typefaceStyle = TextArea.TYPEFACE_BOLD;
                    t.changeTypeface(typefaceStyle);
                }
            }
        });
    }
}

I don't need that complex RichTextEditor I just want my EditText view to take Bold input. — logdev, May 29 '17 at 05:58
You will need to make spannable section of HTML or strings. The current answers are making the entire input box bold, not toggles — OneCricketeer, May 29 '17 at 06:00
@cricket_007 thanks for replying. I am kinda beginner in Android. Can you please elaborate on what you just said. — logdev, May 29 '17 at 06:02
If you are a beginner, then you've started working on a complex problem. Carefully read the post that is in your question... `new StyleSpan(Typeface.BOLD);` Then read that class's documentation — OneCricketeer, May 29 '17 at 06:04
The question I mentioned did not work out that's the reason I asked this question. — logdev, May 29 '17 at 06:17
Which part did not work? The button, or the bold text? Your question here only really asks about a button — OneCricketeer, May 29 '17 at 06:18
When I first click the button it takes bold input but when I clicked the button again to take Normal text as input it was still taking bold text as input. — logdev, May 29 '17 at 06:20
Okay, now that is a problem description, please [edit] the question to include that and your code. — OneCricketeer, May 29 '17 at 06:21

i think he wants to do it when user click on the button - bold. putting in layout might not solve this. – kggoh May 29 '17 at 06:00
