我正在尝试在我的游戏中显示横幅广告,因此我使用 revmob 来显示横幅广告和全屏广告。现在全屏广告正在显示,但横幅广告未显示在 view.addView(banner) 中出现空指针异常。
enter code herepublic class MainActivity extends Activity {
private CCGLSurfaceView mGLSurfaceView;
private boolean isCreated = false;
public static FrameLayout m_rootLayout;
public static String APPLICATION_ID = "514c7c57cee0500d00000001";
public static RevMob revmob;
// This is used to display Toast messages and is not necessary for your app
@Override
protected void onCreate(Bundle savedInstanceState) {
if (!isCreated) {
isCreated = true;
} else {
return;
}
super.onCreate(savedInstanceState);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
revmob = RevMob.start(this, APPLICATION_ID);
displayRevMob();
mGLSurfaceView = new CCGLSurfaceView(this);
setContentView(mGLSurfaceView);
CCDirector.sharedDirector().attachInView(mGLSurfaceView);
getScaledCoordinate();
Global.assetManager = getAssets();
Global.context = this;
Global.loadUserInfo();
CCScene scene = CCScene.node();
scene.addChild(new SplashScene(), -1);
CCDirector.sharedDirector().runWithScene(scene);
//-------------IAP-----------------------
Log.d(TAG1, "Creating IAB helper.");
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.enableDebugLogging(true);
Log.d(TAG1, "Starting setup.");
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
Log.d(TAG, "Setup finished.");
if (!result.isSuccess()) {
// Oh noes, there was a problem.
complain("Problem setting up in-app billing: " + result);
return;
}
// Hooray, IAB is fully set up. Now, let's get an inventory of stuff we own.
Log.d(TAG, "Setup successful. Querying inventory.");
mHelper.queryInventoryAsync(mGotInventoryListener);
}
});
RevMobBanner banner = revmob.createBanner(this);
ViewGroup view = (ViewGroup) findViewById(R.id.banner);
view.addView(banner);
}
public void displayRevMob(){
revmob.showFullscreen(this);
}
}
