multiline edittext where parts are not editable, like fill in the blanks

You can use a TextWatcher() for this requirement

Try this he is the little work around for this

MainActivity

public class MainActivity extends AppCompatActivity {


    EditText myEditText;
    String startText = "I'm The First Part";
    String lastText = "I'm The Last Part";

    SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final SpannableStringBuilder firstStringBuilder = new SpannableStringBuilder(startText);
        final SpannableStringBuilder lastStringBuilder = new SpannableStringBuilder(lastText);

        StyleSpan firstStyleSpan = new StyleSpan(android.graphics.Typeface.BOLD);

        firstStringBuilder.setSpan(firstStyleSpan, 0, firstStringBuilder.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE); // make first 4 characters Bold
        lastStringBuilder.setSpan(firstStyleSpan, 0, lastStringBuilder.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE); // make first 4 characters Bold

        myEditText = findViewById(R.id.myEditText);


        spannableStringBuilder.append(firstStringBuilder);
        spannableStringBuilder.append("   ");
        spannableStringBuilder.append(lastStringBuilder);

        myEditText.setText(spannableStringBuilder);
        Selection.setSelection(myEditText.getText(), startText.length() + 1);

        myEditText.addTextChangedListener(new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {


            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                                          int after) {
                // TODO Auto-generated method stub

            }

            @Override
            public void afterTextChanged(Editable s) {

                if (!s.toString().startsWith(firstStringBuilder.toString())
                        || !s.toString().contains(lastText)) {
                    Log.e("StringBuilder_TAG", spannableStringBuilder.toString());

                    myEditText.setText(spannableStringBuilder);
                    Selection.setSelection(myEditText.getText(), myEditText.getText().length() - lastStringBuilder.length() - 1);
                } else {

                    spannableStringBuilder.clear();
                    spannableStringBuilder.append(s.toString());
                    Log.e("My_TAG", spannableStringBuilder.toString());

                }

            }
        });

    }


}

layout.activity_main

Note

You can also use a TextDrawable here are some links for that

• How to put text in a drawable?
• https://github.com/amulyakhare/TextDrawable
