Icon für jede Klasse?

[idova]

Hallo Leute!

Ich habe das Problem, das bei dieser Anwendung nach der Installation auf Handy oder Simulator/Emulator
das Icon für diese App mehrfach auftaucht. Genauer: für jede Klasse!?
Aber wieso?

Launcher zeight die Aktivities mit:

            <intent-filter>                 <action android:name="android.intent.action.MAIN" />                 <category android:name="android.intent.category.LAUNCHER" />             </intent-filter>

An - also macht es alles richtig. Nehme diese Filter weg, dan verschwinden die

 

[Blalasaadri2]

Warum hast du in der AndroidManifest.xml für jede Activity einen intent-filter? Und zwar immer den Gleichen? Wenn du (außer bei der Activity, die zuerst starten soll) die Zeilen

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

entfernst sollte es glaube ich funktionieren.

Vielen Dank!!

Ich ahnte es... das es so was sein muss... ich muss mir das mal anlesen...

 

[swordi]

genau das passiert, wenn man code kopiert, ohne zu wissen was er tut
