我在ViewPager中有MainActivity，当您触摸适配器内的每个图片时，会打开一个新的Activity。
有人知道如何在加载这些新活动之前展示广告吗？
正如您所看到的，我有一个名为CustomSwipeAdapterCovers的适配器，它负责打开新活动，并在MainActivity显示广告的加载方式，但我不知道如何在非活动上实施广告。
public class MainActivity extends AppCompatActivity {
private static final int START_LEVEL = 1;
private int mLevel;
private Button mNextLevelButton;
private InterstitialAd mInterstitialAd;
private TextView mLevelTextView;
private ViewPager viewPager;
private CustomSwipeAdapterCapas adapter;
//=================================
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create the next level button, which tries to show an interstitial when clicked.
mNextLevelButton = ((Button) findViewById(R.id.next_level_button));
mNextLevelButton.setEnabled(false);
mNextLevelButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
showInterstitial();
}
});
// Create the text view to show the level number.
mLevelTextView = (TextView) findViewById(R.id.level);
mLevel = START_LEVEL;
// Create the InterstitialAd and set the adUnitId (defined in values/strings.xml).
mInterstitialAd = newInterstitialAd();
loadInterstitial();
// Toasts the test ad message on the screen. Remove this after defining your own ad unit ID.
Toast.makeText(this, TOAST_TEXT, Toast.LENGTH_LONG).show();
viewPager = findViewById(R.id.viewpager_main_xml);
adapter = new CustomSwipeAdapterCapas(this);
viewPager.setAdapter(adapter);
}
//=====================================
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}

super.onStop();

AdRequest adRequest = new AdRequest.Builder()
.setRequestAgent("android_studio:ad_template").build();
mInterstitialAd.loadAd(adRequest);
}

mLevelTextView.setText("Level " + (++mLevel));

我也遇到过同样的问题。 在您的情况下，不要打开适配器活动中的插页式广告，而是从下一个适配器活动活动中打开它。 以下是我的解决方案： 将Activity_B视为适配器活动。
假设有3个活动，开放顺序如下：
Activity_A --> Activity_B --> Activity_C.
现在我要在Activity_B和Activity_C之间展示插页式广告。
我先在Activity_A中加载了非页内广告，然后在Activity_C中调用（或显示）。
你可以这样做：
在Activity_A中，即MainActivity添加如下代码：
public void showme(){
mInterstitialAd = new InterstitialAd(this);
mInterstitialAd.setAdUnitId(getString(R.string.interstitial_full_screen));
AdRequest adRequest = new AdRequest.Builder()
.build();
mInterstitialAd.loadAd(adRequest);
mInterstitialAd.setAdListener(new AdListener()
{
@Override
public void onAdClosed()
{
//reload interstitial
AdRequest adRequest = new AdRequest.Builder()
// .addTestDevice("YOUR_DEVICE_ID")
.build();
mInterstitialAd.loadAd(adRequest);
}
});
}
public static void showInterstitial() {
if (mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
}
}
在OnCreate中的Activity_A中调用此showme（）。
在OnCreate中的Activity_C粘贴下面的代码：
Activity_A.showInterstitial();
此外，此方法并未违反插页式广告和横幅广告的任何Google Admob政策。
检查实施此解决方案的应用PF Balance & Claim Status。
在此应用中，主要活动是适配器活动。

您应该喜欢下面的代码...。 在适配器类的顶部声明此代码... 私人InterstitialAd mInterstitialAd;
之后，将其余代码放入onBindViewHolder（）
@Override
public void onBindViewHolder(@NonNull MyHolder holder, final int position) {
Picasso.get()
.load(picsArray[position])
.into(holder.imageView);
mInterstitialAd = new InterstitialAd(context);
mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
mInterstitialAd.loadAd(new AdRequest.Builder().build());
mInterstitialAd.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
// Code to be executed when an ad finishes loading.
}
@Override
public void onAdFailedToLoad(int errorCode) {
// Code to be executed when an ad request fails.
}
@Override
public void onAdOpened() {
// Code to be executed when the ad is displayed.
}
@Override
public void onAdLeftApplication() {
// Code to be executed when the user has left the app.
}
@Override
public void onAdClosed() {
Intent intent = new Intent(context, Full_Image_Activity.class);
intent.putExtra("IMG",picsArray[position]);
context.startActivity(intent);
///// onAdClosed（）方法可以放置您的意图或您想要的东西，这是因为当您关闭添加时，意图必须知道该怎么做... } }）;
}
之后，您可以将代码放入如下所示的item.onClicklistner方法中。
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
} else {
Intent intent = new Intent(context, Full_Image_Activity.class);
intent.putExtra("IMG",picsArray[getAdapterPosition()]);
context.startActivity(intent);
}
}
});
在else {}中，您可以将代码放入intent或您想要执行的任何操作中... 希望它能对很多人有用...
