问题描述
我在 MainActivity 中有一个 ViewPager，当您触摸适配器内的每个图像时，它会打开一个新的 Activity.
I have a ViewPager in MainActivity that open a new Activity when you touch each image that is inside an adapter.
有人知道如何在加载这些新活动之前展示广告吗?
Does anyone know how to show an ad before these new activities are loaded?
如您所见，我有一个名为 CustomSwipeAdapterCovers 的适配器，它负责打开新活动，并在 MainActivity 中显示广告是如何加载的，但我不知道如何在非活动上投放广告.
As you can see, I have an adapter called CustomSwipeAdapterCovers and it is responsible for opening the new activities, and in MainActivity show how the ad is loaded, but I don't know how to implement ads on non-activities.
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);
}
@Override
protected void onStop() {
super.onStop();
}
@Override
protected void onDestroy() {
super.onDestroy();
}
@Override
protected void onRestart() {
super.onRestart();
}
private InterstitialAd newInterstitialAd() {
InterstitialAd interstitialAd = new InterstitialAd(this);
interstitialAd.setAdUnitId(getString(R.string.interstitial_ad_unit_id));
interstitialAd.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
mNextLevelButton.setEnabled(true);
}
@Override
public void onAdFailedToLoad(int errorCode) {
mNextLevelButton.setEnabled(true);
}
@Override
public void onAdClosed() {
// Proceed to the next level.
goToNextLevel();
}
});
return interstitialAd;
}
private void showInterstitial() {
// Show the ad if it's ready. Otherwise toast and reload the ad.
if (mInterstitialAd != null && mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
} else {
Toast.makeText(this, "Ad did not load", Toast.LENGTH_SHORT).show();
goToNextLevel();
}
}
private void loadInterstitial() {
// Disable the next level button and load the ad.
mNextLevelButton.setEnabled(false);
AdRequest adRequest = new AdRequest.Builder()
.setRequestAgent("android_studio:ad_template").build();
mInterstitialAd.loadAd(adRequest);
}
private void goToNextLevel() {
// Show the next level and reload the ad to prepare for the level after.
mLevelTextView.setText("Level " + (++mLevel));
mInterstitialAd = newInterstitialAd();
loadInterstitial();
}
}

推荐答案
我也遇到过同样的问题.在您的情况下，不是从适配器活动打开插页式广告，而是从适配器活动的下一个活动打开它.以下是我的解决方案:将 Activity_B 视为您的适配器活动.
I have also faced this very same issue. In your case instead of opening interstitial ads from adapter activity, open it from next activity of adapter activity. Below is my Solution: Consider Activity_B as your Adapter activity.
假设有3个活动，开启顺序如下:
Suppose there are 3 activities and opening sequence is as follows:
Activity_A --> Activity_B --> Activity_C.
现在我想在 Activity_B 和 Activity_C 之间显示插页式广告.
Now I want to show interstitial Ad between Activity_B and Activity_C.
我先在Activity_A中加载了Interstitial Ad，然后在Activity_C中调用(或显示).
I have first loaded the Interstitial Ad in Activity_A and then call(or show) in Activity_C.
你可以像上面那样做:
在 Activity_A 即 MainActivity 中添加如下代码:
In Activity_A i.e. MainActivity add code like this:
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 内的 Activity_A 中调用这个 showme().
Call this showme() in Activity_A inside OnCreate.
在 Activity_C 中将下面的代码粘贴到 OnCreate 中:
In Activity_C paste below code inside OnCreate:
Activity_A.showInterstitial();
此外，此方法不违反任何关于插页式广告和横幅广告的 Google Admob 政策.
Also, this method doesn't violate any Google Admob policy of interstitial ads as well as banner ads.
