}public class MainApplication extends Application {
@Override
public void onCreate() {
registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
@Override
public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
ActivityMonitor.getInstance().onActivityEvent(activity, ActivityState.CREATED);
}
@Override
public void onActivityStarted(Activity activity) {
ActivityMonitor.getInstance().onActivityEvent(activity, ActivityState.STARTED);
}
@Override
public void onActivityResumed(Activity activity) {
ActivityMonitor.getInstance().onActivityEvent(activity, ActivityState.RESUMED);
}
@Override
public void onActivityPaused(Activity activity) {
ActivityMonitor.getInstance().onActivityEvent(activity, ActivityState.PAUSED);
}
@Override
public void onActivityStopped(Activity activity) {
ActivityMonitor.getInstance().onActivityEvent(activity, ActivityState.STOPPED);
}
@Override
public void onActivitySaveInstanceState(Activity activity, Bundle outState) {
}
@Override
public void onActivityDestroyed(Activity activity) {
ActivityMonitor.getInstance().onActivityEvent(activity, ActivityState.DESTROYED);
}
});
}
}
或者
public class BaseActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActivityMonitor.getInstance().onActivityEvent(this, ActivityState.CREATED);
}
@Override
protected void onStart() {
super.onStart();
ActivityMonitor.getInstance().onActivityEvent(this, ActivityState.STARTED);
}
...
}
- 监听App的前后台变化
ActivityMonitor.getInstance().registerAppStateChangeListener(new ActivityMonitor.OnAppStateChangeListener() {
@Override
public void onAppStateChange(boolean foreground) {
if (foreground) {
...
} else {
...
}
}
});
- 获取当前的Activity：可用于解决Activity跳转时，由于层层封装导致无法拿到当前Activity的引用从而无法重载过渡动画的问题
Activity currentActivity = ActivityMonitor.getInstance().getTopActivity();
if (currentActivity != null) {
currentActivity.overridePendingTransition(R.anim.enter_anim, R.anim.exit_anim);
}
