我有BroadcastReceiver类:
public class IntentReceiver extends BroadcastReceiver {
final String tag = "Intent Intercepter";
@Override
public void onReceive(Context context, Intent intent) {
try {
String data = intent.getStringExtra("sms_body");
Log.i(tag, data);
Toast.makeText(context, data.subSequence(0, data.length()), Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(context, "Intercepted", Toast.LENGTH_LONG).show();
}
}

我们如何在 Spring 中记录每个 bean 实例化?

我在 Android 上使用具有单活动模式的 Android 架构组件。我使用的导航模式是 BottomNavigationView。我实际上希望父活动没有 ActionBar,但将我的主题设置为 NoActionBar 类型会使应用程序崩溃。在 Activity 中设置导航已完成,如下所示
val navController = findNavController(R.id.nav_host_fragment)
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
val appBarConfiguration = AppBarConfiguration(
setOf(R.id.navigation_popular, R.id.navigation_top_rated, R.id.navigation_favorites)
)
