    <p>I'm trying to apply a font color to text in an EditText as you type text. However, its just very inconsistent, meaning that sometimes if you type a space, the text preceding that space will go back to the default black color. Or if I put my cursor in the middle of a word and start typing the entire word changes color and not just the text I'm typing. The bold, italic and underline seem to work well though. How can I guarantee that only the text I'm typing will be affected with regards to font color? </p> <p>See "SIZE AND COLOR" comment below...</p> <pre><code> contentEdit.addTextChangedListener(new TextWatcher() { public void afterTextChanged(Editable s) { //add style as the user types if a toggle button is enabled ToggleButton boldButton = (ToggleButton) findViewById(R.id.bold); ToggleButton emButton = (ToggleButton) findViewById(R.id.italic); ToggleButton underlineButton = (ToggleButton) findViewById(R.id.underline); int position = Selection.getSelectionStart(contentEdit.getText()); try{ if (position &lt; 0){ position = 0; } if (position &gt; 0){ if (styleStart &gt; position || position &gt; (cursorLoc + 1)){ //user changed cursor location, reset if (position - cursorLoc &gt; 1){ //user pasted text styleStart = cursorLoc; } else{ styleStart = position - 1; } } if (boldButton.isChecked()){ StyleSpan[] ss = s.getSpans(styleStart, position, StyleSpan.class); for (int i = 0; i &lt; ss.length; i++) { if (ss[i].getStyle() == android.graphics.Typeface.BOLD){ s.removeSpan(ss[i]); } } s.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), styleStart, position, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); } if (emButton.isChecked()){ StyleSpan[] ss = s.getSpans(styleStart, position, StyleSpan.class); for (int i = 0; i &lt; ss.length; i++) { if (ss[i].getStyle() == android.graphics.Typeface.ITALIC){ s.removeSpan(ss[i]); } } s.setSpan(new StyleSpan(android.graphics.Typeface.ITALIC), styleStart, position, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); } if (underlineButton.isChecked()){ UnderlineSpan[] ss = s.getSpans(styleStart, position, UnderlineSpan.class); for (int i = 0; i &lt; ss.length; i++) { s.removeSpan(ss[i]); } s.setSpan(new UnderlineSpan(), styleStart, position, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); } //SIZE AND COLOR////////////////////////////////////////////////////// s.setSpan(new ForegroundColorSpan(m_color), position, position, Spannable.SPAN_INCLUSIVE_INCLUSIVE); s.setSpan(new AbsoluteSizeSpan(m_curSize, true), position, position, Spannable.SPAN_INCLUSIVE_INCLUSIVE); } } catch(Exception e){ //Toast.makeText(m_ctx, m_ctx.gets, Toast.LENGTH_LONG).show(); showMessage(R.string.NOTE_WARNING_STYLE,m_utils.MSGTYPE_WARNING); } cursorLoc = Selection.getSelectionStart(contentEdit.getText()); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
