如何在Android的另一个线程中运行方法？

Question

I have a MainActivity class in Android that loads first screen. When starting, I need to run another method in another thread and then either show message or go to another screen. For UI not to hang. How to do this? In which place of code?

// UPDATED CODE

import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;

import android.view.Menu;
import android.widget.Toast;


public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //Context context=getApplicationContext();
    String Internet=String.valueOf(isNetworkAvailable(this));
    Toast toast = Toast.makeText(this, Internet, Toast.LENGTH_SHORT);
    toast.show();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public static boolean isNetworkAvailable(Context context) 
{
    return ((ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo() != null;
}

}

You can go the Java route and utilize a normal Thread. Note, however, that you will need a Handler (class located in the Android SDK) to propagate your changes to the UI.
The more Android-kind-of way would be an AsyncTask . It is designed specifically for tasks that have to run in parallel to the UI and provides a mechanism to call back to the UI, so you don't have to implement that yourself (exactly what you would do with the handler if you decide to choose the furst option).
