Highlight Text in TextView or WebView

Is it possible to Highlight text in a TextView 开发者_JAVA技巧or WebView?

I see it is possible in a EditText

Highligh text in a EditText

I'd like to do the same in TextView or WebView.

Thats Possible?

enable TextView's Spannable storage! by default Spannable storage in EditText is true.

so

TextView myTV = (TextView)findViewById(R.id.textView1);
String  textString = "StackOverFlow Rocks!!!"; 
Spannable spanText = Spannable.Factory.getInstance().newSpannable(textString);
spanText.setSpan(new BackgroundColorSpan(0xFFFFFF00), 14, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
myTV.setText(spanText);

As well you could use this one solution for WebView. Call findAllAsync

webview.findAllAsync(((EditText) findViewById(R.id.edit)).getText().toString());

than add FindListener to WebView

    webview.setFindListener(new FindListener() {

        @Override
        public void onFindResultReceived(int activeMatchOrdinal, int numberOfMatches, boolean isDoneCounting) {
            Toast.makeText(getApplicationContext(), "Matches: " + numberOfMatches, Toast.LENGTH_LONG).show();
        }
    });

Iterate in result with webview.findNext(false); where false/true shows the direction.

But this solution was added in API level 16!!! Instead of you can setup JavaScript for higlihting - http://www.nsftools.com/misc/SearchAndHighlight.htm

For TextView

You can use textView.setTextIsSelectable(true) in your activity or fragment or adapter.

Actually, you do not have to develop this feature by yourself. You just need to use EditText instead TextView, while you set the android:editable of EditText to false.
