我正在尝试在用户按下菜单按钮时暂停菜单(暂停游戏)。游戏确实成功暂停,但没有画出来...也许它正在我的GLSurfaceView下面绘制?这是我的代码。

public class GameActivity extends Activity {

private GLSurfaceView mGLSurfaceView;
private static final String TAG = "Game";
private MainGamePanel mGame;

private View mPauseMessage = null;

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

    SharedPreferences prefs = getSharedPreferences("GameSettings", MODE_PRIVATE);

    setContentView(R.layout.main);
    mGLSurfaceView = (GLSurfaceView) findViewById(R.id.glsurfaceview);
    mPauseMessage = findViewById(R.id.pausedMessage);

    mGLSurfaceView.setEGLConfigChooser(false); // 16 bit, no z-buffer

    mGame = new MainGamePanel();
    mGame.setSurfaceView(mGLSurfaceView);

    ....
    mGLSurfaceView.setRenderer(mGame.getRenderer());

}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    boolean result = true;
    if (keyCode == KeyEvent.KEYCODE_MENU) {
        if (mGame.isPaused()) {
            this.resume();
            if (mPauseMessage != null) {
                mPauseMessage.setVisibility(View.GONE);
            }
        } else {
            this.pause();
            if (mPauseMessage != null) {
                mPauseMessage.setVisibility(View.VISIBLE);
            }
        }
    }
    return result;
}

protected void pause() {
    super.onPause();

    mGame.onPause();
    mGLSurfaceView.onPause();
}


protected void resume() {
    super.onResume();

    mGame.onResume();
    mGLSurfaceView.onResume();
}

从我的XML:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<android.opengl.GLSurfaceView xmlns:android="http://schemas.android.com/apk/res/android" 
            android:id="@+id/glsurfaceview"
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
    />
    <LinearLayout
        android:id="@+id/pauseMenu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="gone">
    <ImageView 
    android:id="@+id/pausedMessage"
    android:src="@drawable/pause"
    android:layout_height="wrap_content" 
    android:layout_width="wrap_content" 
    android:layout_gravity="center"/>
</LinearLayout>
</FrameLayout>

也许你在某处说了一句话:

mGLSurfaceView.setZOrderOnTop(true);

哪个覆盖OpenGL以绘制任何内容,即使您在RelativeLayout中有其他视图。如果有的话,请尝试对此进行评论。

否则你可以试试这个:(谢谢你user2610335)

mGLSurfaceView.setZOrderOnTop(false)

我遇到过类似的问题。但在我的情况下,pauseMenu是不可见的,但不是GONE。当我把它改成GONE时,一切正常。但这只发生在一些设备上。也许试试View.bringToFront()
