InflateException when trying to use a Snackbar

Question

I have a Snackbar, which is supposed to show in case no resorts are found after making a request to a server for data. Every time the Snackbar needs to be shown I get this exception:

java.lang.RuntimeException: An error occurred while executing doInBackground()

My current class extends ListActivity and is implementing a ActionBar.

The line where it is giving an error:

pDialog.dismiss();
                Snackbar.make(parentLayout, "No resorts found", Snackbar.LENGTH_INDEFINITE)
                        .setAction("CLOSE", new View.OnClickListener() {
                            @Override
                            public void onClick(View view) {
                                Bundle data = getIntent().getExtras();
                                Intent i = new Intent(Result.this, OptionList.class);
                                i.putExtras(data);
                                setResult(RESULT_OK, getIntent());
                                finish();
                            }
                        })
                        .setActionTextColor(getResources().getColor(android.R.color.holo_blue_dark ))
                        .show();

If I replace the Snackbar message with a Toast it works fine.

Parent layout code:

parentLayout = findViewById(android.R.id.content);

The Snackbar worked perfectly before I added the action bar.

For this activity I'm using a Theme.Holo.Light.ActionBar Android manifest:

<activity android:name=".Result"
        android:launchMode="singleTop"
        android:theme="@android:style/Theme.Holo.Light.DarkActionBar"
        android:parentActivityName="com.tripoffbeat.OptionList"/>

In my styles.xml my theme is <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">.

Answer 1

When Snackbar inflates its content layout, it cannot inflate a Button from that layout, because it lacks to find ?attr/colorAccent from the theme of the current context. That's happening, because the theme of your activity is not a descendant of AppCompat theme.

So, instead of:

android:theme="@android:style/Theme.Holo.Light.DarkActionBar"

apply some appcompatish theme. Removing that line from manifest would resolve your error, assuming the theme of your application is Theme.AppCompat.Light.DarkActionBar.
