InflateException beim Versuch, eine Snackbar zu verwenden

Question

Ich habe eine Snackbar, die angezeigt werden soll, wenn keine Resorts nach einer Anfrage an einen Server für Daten gefunden werden. Jedes Mal, wenn die Snackbar muss gezeigt werden, ich diese Ausnahme erhalten:

Meine aktuelle Klasse erweitert ListActivity und ein ActionBar Umsetzung.

Die Linie, wo es einen Fehler geben:

mit einem Toast

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(); 

Wenn ich ersetzen Sie die Snackbar Nachricht Fein es funktioniert.

</LinearLayout> 

Eltern Layout-Code:

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

Die Snackbar funktionierte perfekt, bevor ich die Aktionsleiste hinzugefügt.

Für diese Tätigkeit Ich bin mit einem 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 meinem styles.xml mein Thema ist <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">.

Answer 1

Wenn Snackbarits content layout aufbläst, es cannot inflate a Button von diesem Layout, weil es ?attr/colorAccent aus dem Thema des aktuellen Kontextes finden fehlt. Das passiert, weil das Thema Ihrer Aktivität kein Nachkomme des Themas AppCompat ist.

Anstatt also:

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

einige appcompatish Thema gelten. Wenn Sie diese Zeile aus dem Manifest entfernen, wird der Fehler behoben, vorausgesetzt, das Thema Ihrer Anwendung lautet Theme.AppCompat.Light.DarkActionBar.
