Question

我是Android App Development的新手，并创建了一个简单的服务应用。它有一个启动服务的按钮和一个按钮来停止服务的各种方法。以下是我的代码：

App3_main.java

package eg.app3;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

public class App3_main extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_app3_main);
}

public void startservice(View view)
{
    Intent intent = new Intent(this,MyService.class);
    startservice(intent); //this is where I'm getting the error mentioned in the title
}

public void stopservice(View view)
{
    Intent intent = new Intent(this,MyService.class);
    stopservice(intent); //this is where I'm getting the error mentioned in the title
}

}

MyService.java

package eg.app3;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;

public class MyService extends Service {
public MyService() {
}

@Override
public void onCreate() {
    super.onCreate();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Toast.makeText(this,"Service Started",Toast.LENGTH_LONG).show();
    return START_STICKY;

}


@Override
public void onDestroy() {
    Toast.makeText(this,"Service Stopped",Toast.LENGTH_LONG).show();
}

@Override
public IBinder onBind(Intent intent) {
    return null;
}
}

请指导我错在哪里。

Answer 1

替换：

startservice(intent);

使用：

startService(intent);

然后，替换：

stopservice(intent);

使用：

stopService(intent);

与大多数编程语言一样，Java区分大小写。

错误：视图无法应用于Intent
