How to change a TextView's style at runtime

Question

I have an android app on which, when the user taps a TextView, I would like to apply a defined style.

I thought to find a textview.setStyle() but it doesn't exists. I tried

textview.setTextAppearance(); 

but it does not work.

Answer 1

Like Jonathan suggested, using textView.setTextTypeface works, I just used it in an app a few seconds ago.

textView.setTypeface(null, Typeface.BOLD); // Typeface.NORMAL, Typeface.ITALIC etc. 

Answer 2

I did this by creating a new XML file res/values/style.xml as follows:

<?xml version="1.0" encoding="utf-8"?> <resources>      <style name="boldText">         <item name="android:textStyle">bold|italic</item>         <item name="android:textColor">#FFFFFF</item>     </style>      <style name="normalText">         <item name="android:textStyle">normal</item>         <item name="android:textColor">#C0C0C0</item>     </style>  </resources> 

I also have an entries in my "strings.xml" file like this:

<color name="highlightedTextViewColor">#000088</color> <color name="normalTextViewColor">#000044</color> 

Then, in my code I created a ClickListener to trap the tap event on that TextView: EDIT: As from API 23 'setTextAppearance' is deprecated

    myTextView.setOnClickListener(new View.OnClickListener() {                 public void onClick(View view){                     //highlight the TextView                     //myTextView.setTextAppearance(getApplicationContext(), R.style.boldText);     if (Build.VERSION.SDK_INT < 23) {        myTextView.setTextAppearance(getApplicationContext(), R.style.boldText);     } else {        myTextView.setTextAppearance(R.style.boldText);     }      myTextView.setBackgroundResource(R.color.highlightedTextViewColor);                 }             }); 

To change it back, you would use this:

if (Build.VERSION.SDK_INT < 23) {     myTextView.setTextAppearance(getApplicationContext(), R.style.normalText); } else{    myTextView.setTextAppearance(R.style.normalText); } myTextView.setBackgroundResource(R.color.normalTextViewColor);
