英文:
Calling method inside service activity in Android
问题
MainActivity.java
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// 从这里调用服务活动内的方法
s.method();
}
});
Service.java
public class mservice extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
public void method() {
Toast.makeText(this, "调用", Toast.LENGTH_LONG).show();
}
}
在 MainActivity 中，您可以通过在按钮的点击事件中调用 s.method() 来调用 Service 活动内的方法。但是请注意，您需要确保在调用 s.method() 之前，您已经正确地初始化了 mservice 类的实例 s。另外，确保您已经在 AndroidManifest.xml 中正确地声明了 Service。
