在我的活动A中，此视图调用两次，但在我的活动B中，没有问题。
活动A是非常简单的布局，只有一些linearLayout。我快要疯了，可能是什么问题？
这是我的AdBannerView：
public class AdBannerView extends LinearLayout {
public ImageView adIcon, adInstall;
public TextView_ adTitle, adDesc;
public ProgressBar adProgress;
RelativeLayout adWrapperLay;
private boolean impSent, adLoaded = false;
public AdBannerView(Context context) {
super(context);
}
public AdBannerView(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
public AdBannerView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
private void init(Context context) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View wrapper = inflater.inflate(R.layout.view_ad_banner, this, true);
adIcon = (ImageView) wrapper.findViewById(R.id.adIcon);
adInstall = (ImageView) wrapper.findViewById(R.id.adInstall);
adTitle = (TextView_) wrapper.findViewById(R.id.adTitle);
adDesc = (TextView_) wrapper.findViewById(R.id.adDesc);
adProgress = (ProgressBar) wrapper.findViewById(R.id.adProgress);
adWrapperLay = (RelativeLayout) wrapper.findViewById(R.id.adWrapperLay);
Log.d("AdBannerView", "before loadAd()");
if(NativeAdManager.getInstance().isAdEnabled)
loadAd();
}
public void loadAd(){
if(adLoaded)
return;
adLoaded = true;
Log.d("AdBannerView", "loadAd() request");
NativeAdManager.getInstance().getAd(getContext(), new NativeAdManager.AdListener() {
@Override
public void adLoaded(final NativeAdResponse.Ads[] ads) {
/* load img */
Picasso
.with(getContext())
.load(ads[0].adIc)
.into(adIcon);
/* load title */
adTitle.setText(""+ads[0].adTit);
adDesc.setText(""+ads[0].adDesc);
/* click listener */
adInstall.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
App app = (App) getContext().getApplicationContext();
app.getUiController().loadUrlWithoutAdBlocker(ads[0].adClk);
}
});
/* show this layout */
showAd(ads[0].adBeacons);
Log.d("AdBannerView", "loaded with size = " + ads.length);
}
});
}
private void showAd(final NativeAdResponse.adBeacons[] adBeacons) {
adProgress.setVisibility(GONE);
adIcon.setVisibility(VISIBLE);
}
}
我包括这样的布局：
<.... AdBannerView match_parent etc />
证明绘图两次的日志：

有问题的活动A：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

<package.AdManager.AdBannerView
android:layout_width="match_parent"

</RelativeLayout>
活动A.java（I deleted everything in layout and class except of AdBannerView but still same）：

setContentView(getLayoutResourceId());
/*

overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);

基地：
public abstract class Base extends Activity {

@Override
public void onCreate(Bundle b) {
super.onCreate(b);
setContentView(getLayoutResourceId());
keyBoardListener();
new Handler().postDelayed(new Runnable() {

}, 50);
}
@Override

答案 0 :(得分：2)
这是你的错误:)希望
你已经在你的基础上调用了setContentView，然后在你的派生类中你调用了super create（它调用了setContentView [创建了adElement]）但是之后再次调用setContentView（getLayoutResourceId（））; （这次来自你的派生类，它会覆盖布局，但即使它没有调用它实际上是我想象的相同内容，这也就是为什么它看起来很正常:)。
所以修复应该很简单 - 从活动A中删除setContentView（getLayoutResourceId（）），因为它已经从基础活动调用了
