copied!<p>I figure out a simple solution by using a tag like HTML</p> <pre><code>ImageBtn.setOnClickListener(new OnClickListener() { @override public void onClick(View view) { // TODO Auto-generated method stub mContentEdit.append("[1;34m [m"); //this is the tag I use //here I simplely append new tag to the end ,we can also add this tag where cursor is } }); </code></pre> <p>add a TextWatcher for my EditText;</p> <pre><code> mContentEdit.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub switch(mInsertIndex){ case 1: mSelection = mContentEdit.getSelectionStart(); break; case 2: mContentEdit.setSelection(mSelection); break; //recover the cursor's position } } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub switch (mInsertIndex) { case 1: //this is p:Pattern p = Pattern.compile("\\[[\\d{1};]*(3\\d{1})m(.*?)\\[[\\d;]*m"); Matcher m = p.matcher(s.toString()); StringBuffer sb = new StringBuffer(); while(m.find()){ m.appendReplacement(sb, "<font color=#"+CssUtil.getColor(m.group(1))+">"+"[1;"+m.group(1)+"m"+m.group(2)+"[m"+"</font>"); } //add a tag otherwise the next time we input,color will be gone; m.appendTail(sb); mInsertIndex = 2; mContentEdit.setText(Html.fromHtml(sb.toString())); break; //replace tag by html color case 2: mInsertIndex = 1; break; //avoid recursive message loop } } </code></pre> <p>this code does good job for my application. I can post the raw text in edittext directly to website, and website will parse the tags for css color;</p> <p>But there is still defect:</p> <p>1: What if I don't want see the tags? In my question , what I need is actually a color state machine,once btn pressed ,where ever u input ,the color will make effect. But in my solution ,I have to input in the tags.</p> <p>2:With the growth of the input length, efficiency might be a problem; As u see, a regex is employed;</p> <p>So, still looking forward to a hero to solve my problem!</p>
