how to insert image to a editText

Question

I want to insert a image to a editText my code is:

  CharSequence charSeq= editText.getText()+\" \";
  SpannableString ss2 = new SpannableString(charSeq); 
          


        

Answer 1

Do something like this (note: you can reuse SpannableStringBuilder)

editText = (EditText)mRoot.findViewById(R.id.content);
ImageSpan imageSpan = new ImageSpan(preview);

SpannableStringBuilder builder = new SpannableStringBuilder();
builder.append(editText.getText());

// this is a string that will let you find a place, where the ImageSpan is.
String imgId = "[img=1]"; 

int selStart = editText.getSelectionStart();

// current selection is replaceв with imageId
builder.replace(editText.getSelectionStart(), editText.getSelectionEnd(), imgId);

// This adds a span to display image where the imageId is. If you do builder.toString() - the string will contain imageId where the imageSpan is.
// you can use it later - if you want to find location of imageSpan in text;
builder.setSpan(imageSpan, selStart, selStart + imgId.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
editText.setText(builder);

Note: See follow up answer for dealing with partial deletion of tags

    }

    private static final Spannable.Factory spannableFactory = Spannable.Factory.getInstance();

    private static boolean addImages(Context context, Spannable spannable) {
        Pattern refImg = Pattern.compile("\\Q[img src=\\E([a-zA-Z0-9_]+?)\\Q/]\\E");
        boolean hasChanges = false;

        Matcher matcher = refImg.matcher(spannable);
    while (matcher.find()) {
        boolean set = true;
        for (ImageSpan span : spannable.getSpans(matcher.start(), matcher.end(), ImageSpan.class)) {
            if (spannable.getSpanStart(span) >= matcher.start()
             && spannable.getSpanEnd(span) <= matcher.end()
               ) {
                spannable.removeSpan(span);
            } else {
                set = false;
                break;
            }
        }
        String resname = spannable.subSequence(matcher.start(1), matcher.end(1)).toString().trim();
        int id = context.getResources().getIdentifier(resname, "drawable", context.getPackageName());
        if (set) {
            hasChanges = true;
            spannable.setSpan(  new ImageSpan(context, id),
                                matcher.start(),
                                matcher.end(),
                                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE

        }
    }

        return hasChanges;
    }
    private static Spannable getTextWithImages(Context context, CharSequence text) {
        Spannable spannable = spannableFactory.newSpannable(text);
        addImages(context, spannable);
        return spannable;
    }
}

Use:

in res/layout/mylayout.xml:

            <com.xyz.customandroid.TextViewWithImages
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor="#FFFFFF00"
                android:text="@string/can_try_again"
                android:textSize="12dip"
                style=...
                />

in res/values/strings.xml:

<string name="can_try_again">Press [img src=ok16/] to accept or [img src=retry16/] to retry</string>

where ok16.png and retry16.png are in the res/drawable/ folder

Answer 3

Try this, i hope you are in search of this:

   <EditText
        android:id="@+id/editText1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:drawableLeft="@drawable/icon">
    </EditText>

The same thing you can try for:

android:drawableRight
android:drawableTop
android:drawableBottom
android:drawablePadding

I guess, You'll also need some functionality for text-editing: image should be removed if one character of it is removed; this class can help (removes all the image text-placeholder if a char of it is removed)

public class ImageSpanTextWatcher implements TextWatcher {
    Object[] mTouchedSpans;
    int[] mSpanLength;
    boolean replacing = false;

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        if (s instanceof SpannableStringBuilder) {
            SpannableStringBuilder ssb = (SpannableStringBuilder) s;
            mTouchedSpans = ssb.getSpans(start, start + count, ImageSpan.class);
            if (mTouchedSpans != null && mTouchedSpans.length > 0) {
                mSpanLength = new int[mTouchedSpans.length];
                for (int i = 0; i < mTouchedSpans.length; i++) {
                    mSpanLength[i] = ssb.getSpanEnd(mTouchedSpans[i]) - ssb.getSpanStart(mTouchedSpans[i]);
                }
            }
        }
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        if (s instanceof SpannableStringBuilder) {
            SpannableStringBuilder ssb = (SpannableStringBuilder) s;

            if (replacing)
                return;
            replacing = true;
            if (mTouchedSpans != null && mTouchedSpans.length > 0)
                for (int i = 0; i < mTouchedSpans.length; i++) {
                    int newLen = ssb.getSpanEnd(mTouchedSpans[i]) - ssb.getSpanStart(mTouchedSpans[i]);
                    if (newLen < mSpanLength[i]) {
                        ssb.replace(ssb.getSpanStart(mTouchedSpans[i]), ssb.getSpanEnd(mTouchedSpans[i]), "");
                    }
                }
            mTouchedSpans = null;
            mSpanLength = null;
            replacing = false;
        }
    }

    @Override
    public void afterTextChanged(Editable s) {}
}

Answer 5

With this,you would get the image left align and also would get cursor after the image.Try using:

mEditText.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon,0, 0,0);

Answer 6

I am an inserting and deleting an image in EditText by this way:

Customer button Insertion:

private void addImageInEditText(Drawable drawable) {

        drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());

        int selectionCursorPos = messageEditText.getSelectionStart();
        messageEditText.getText().insert(selectionCursorPos, ".");
        selectionCursorPos = messageEditText.getSelectionStart(); 
        SpannableStringBuilder builder = new SpannableStringBuilder(messageEditText.getText());
        int startPos = selectionCursorPos - ".".length();
        builder.setSpan(new ImageSpan(drawable), startPos, selectionCursorPos, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        messageEditText.setText(builder);
        messageEditText.setSelection(selectionCursorPos);
    }

Custom button Deletion:

private void deleteImageFromEditText() {
        String msgEditText = messageEditText.getText().toString();
        LOGE(TAG, "text length : " + msgEditText.length());
        if (msgEditText.length() > 0) {
            int selectionCursorPos = messageEditText.getSelectionStart();
            int endPosition = messageEditText.getText().length();
            LOGE(TAG, "cursor Pos: " + selectionCursorPos + " endPosition : " + endPosition);

            if (selectionCursorPos > 0) {
                int deletingObjectStartPos = selectionCursorPos - 1;
                messageEditText.getText().delete(deletingObjectStartPos, selectionCursorPos);
                messageEditText.setSelection(deletingObjectStartPos);
            }
        } else {
            messageEditText.setText("");
        }
    }

Drawable can be pass by multiple ways for testing I am doing like this:

Drawable drawable = getResources().getDrawable(R.drawable.ic_action_filter);
addImageBetweentext(drawable);
