我是 admobi 新手，我正在添加插页式添加，我想以编程方式关闭添加。经过一番研究，我发现这是不可能的，只有这个我们需要使用 onbackpress 来关闭添加，因为当您按下 backpress 键时它会关闭。我已经尝试过，但它给出了类似的错误 java.lang.IllegalStateException：必须从进程的主线程调用。 在 android.app.Activity.onKeyUp(Activity.java:2131) 我正在尝试从失去的两天中解决它，但它不起作用，请任何人解决它并将其交给我，我将非常感谢。我在下面添加我的代码
public class MainActivity extends Activity {
private InterstitialAd interstitial;
protected boolean active = true;
protected int splashtime = 3000;
@Override
protected void onSaveInstanceState(Bundle outState) {
// TODO Auto-generated method stub
//super.onSaveInstanceState(outState);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main.xml
setContentView(R.layout.activity_main);
// Prepare the Interstitial Ad
interstitial = new InterstitialAd(MainActivity.this);
// Insert the Ad Unit ID
interstitial.setAdUnitId("ca-app-pub-4412961323059248/9600290618");
final TelephonyManager tm =(TelephonyManager)getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);
String deviceid = tm.getDeviceId();
//Locate the Banner Ad in activity_main.xml
AdView adView = (AdView) this.findViewById(R.id.adView);
// Request for Ads
AdRequest adRequest = new AdRequest.Builder()
// Add a test device to show Test Adss
/* .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("9F0D0FB0280794109822A582BFFB7EC1")*/
.build();
// Load ads into Banner Ads
adView.loadAd(adRequest);
// Load ads into Interstitial Ads
interstitial.loadAd(adRequest);
Thread splash = new Thread()
{
@Override
public void run()
{
// TODO Auto-generated method stub
super.run();
try
{
int waitid = 0;
while(active && (waitid < splashtime))
{
sleep(1000);
if(active)
{
waitid+=100;
}
}
}
catch (InterruptedException e)
{
// TODO: handle exception
}
finally
{
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK));
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));
}
}
};
splash.start();
// Prepare an Interstitial Ad Listener
interstitial.setAdListener(new AdListener() {
public void onAdLoaded() {
// Call displayInterstitial() function
//interstitial.show();
displayInterstitial();
}
});
}
public void displayInterstitial() {
// If Ads are loaded, show Interstitial else show nothing.
if (interstitial.isLoaded()) {
interstitial.show();
}
}
}
因此，经过这么多研究，我找到了另一种解决方案，即使用计时器，这对我有用
调整这个答案：
Timer timer = new Timer();
SwitchPage(6);
private void SwitchPage(int seconds) {
// TODO Auto-generated method stub
timer = new Timer(); // At this line a new Thread will be created
timer.schedule(new SwitchPageTask(), 10000, seconds * 10000); // delay in milliseconds
}
class SwitchPageTask extends TimerTask {
@Override
public void run() {
// As the TimerTask run on a separate thread from UI thread we have
// to call runOnUiThread to do work on UI thread.
runOnUiThread(new Runnable() {
public void run() {
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK));
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));
finish();
SwitchPageTask.this.cancel();
Intent intent=new Intent(MainActivity.this,Second.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
SwitchPageTask.this.cancel();
finish();
}
});
在主线程的Handler内部实现key_up和key_down事件。
从启动线程内部，向已实现的处理程序发送一条消息以执行 key_up 和 key_down 事件。
import android.os.Handler;
public class MainActivity extends Activity {
private InterstitialAd interstitial;
protected boolean active = true;
protected int splashtime = 3000;
private Handler handler;
@Override
protected void onSaveInstanceState(Bundle outState) {
// TODO Auto-generated method stub
//super.onSaveInstanceState(outState);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main.xml
setContentView(R.layout.activity_main);
//Creating new Handler object
handler = new Handler(){
@Override
public void handleMessage(Message msg) {
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK));
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));
}
};
// Prepare the Interstitial Ad
interstitial = new InterstitialAd(MainActivity.this);
// Insert the Ad Unit ID
interstitial.setAdUnitId("ca-app-pub-4412961323059248/9600290618");
final TelephonyManager tm =(TelephonyManager)getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);
String deviceid = tm.getDeviceId();
//Locate the Banner Ad in activity_main.xml
AdView adView = (AdView) this.findViewById(R.id.adView);
// Request for Ads
AdRequest adRequest = new AdRequest.Builder()
// Add a test device to show Test Adss
/* .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("9F0D0FB0280794109822A582BFFB7EC1")*/
.build();
// Load ads into Banner Ads
adView.loadAd(adRequest);
// Load ads into Interstitial Ads
interstitial.loadAd(adRequest);
Thread splash = new Thread()
{
@Override
public void run()
{
// TODO Auto-generated method stub
super.run();
try
{
int waitid = 0;
while(active && (waitid < splashtime))
{
sleep(1000);
if(active)
{
waitid+=100;
}
}
}
catch (InterruptedException e)
{
// TODO: handle exception
}
finally
{
handler.sendEmptyMessage(0);
}
}
};
splash.start();
// Prepare an Interstitial Ad Listener
interstitial.setAdListener(new AdListener() {
public void onAdLoaded() {
// Call displayInterstitial() function
//interstitial.show();
displayInterstitial();
}
});
}
public void displayInterstitial() {
// If Ads are loaded, show Interstitial else show nothing.
if (interstitial.isLoaded()) {
interstitial.show();
}
}
}
在您想要从活动中执行后压的地方调用此方法
super.onBackPressed();
