možno, dať textview do GLSurfaceview je nemožné? Chcem zobraziť text cez glsurfaceview.

tak som hľadal google. a nakreslite Text pomocou Plátna, bitmapy, farby. ale chyba.

takže skúsim dať textview do GLSurfaceView.

Vďaka.

odpovede:

GLSurfaceView je podtriedou SurfaceViewa podtrieda View, tak dajte TextView vnútri GLSurfaceView nebudem pracovať.

GLSurfaceView nie je podtriedou ViewGroup.

Mali by ste použiť a ViewGroup namiesto toho ich zabaliť.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<android.opengl.GLSurfaceView
android:layout_width="match_parent"
android:layout_height="match_parent" />

<TextView
android:layout_width="wrap_content"
android:text="@string/app_name"
android:layout_height="wrap_content"
android:layout_gravity="center" />
</FrameLayout>
