Wenn ich Unity als Unteransicht verwende, wird mir ein schwarzer Bildschirm angezeigt

Ich verwende Unity mit Android und es funktioniert, wenn die Ansicht im Vollbildmodus angezeigt wird. Wenn ich sie jedoch in eine Unteransicht verwandle, wird auf dem Bildschirm nichts angezeigt.

Es funktioniert als Vollbild:

Intent intent = new Intent(this, UnityPlayerActivity.class);
intent.putExtra("arguments", "data from android");
startActivity(intent);

Diese Fragen bleiben ebenfalls unbeantwortet:

Ich habe die Lösungen ausprobiert, die sie haben, aber keine scheint funktioniert zu haben.

Zeigen Sie die Unity-Szene als Unteransicht in Android Studio an

Mein aktuelles MainActivity / Unity Manifest:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        m_UnityPlayer = new UnityPlayer(this);
        int glesMode = m_UnityPlayer.getSettings().getInt("gles_mode", 1);
        boolean trueColor8888 = false;
        m_UnityPlayer.init(glesMode, trueColor8888);

        setContentView(R.layout.activity_main);

        FrameLayout layout = (FrameLayout) findViewById(R.id.frameLayout2);
        LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
        layout.addView(m_UnityPlayer.getView(), 0, lp);
    }

Sie können es nur mit Rahmenlayout erreichen, MainActivitysollte erweitert werden Activity, nicht UnityPlayerActivity. Fügen Sie diese beiden Zeilen zur Aktivität in der hinzu AndroidManifest.xml.

<meta-data android:name="unityplayer.UnityActivity" android:value="true" />
<meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" />
