解决方案

您的活动下面写下code中的OnCreate（）：

 如果（！NetworkCheckClass.haveNetworkConnection（SplashActivity.this））{
Toast.makeText（SplashScreen.this，没有互联网连接！，Toast.LENGTH_LONG）.show（）;意向意图=新意图（Settings.ACTION_WIRELESS_SETTINGS）;
startActivity（意向）;
}
其他{
 //你的code如果连接可用
} //闪屏计时器
 

im working on an android application in which i have a main activity and Activity_splash.xml which is my splash screen activity. what i want is when my app is launched, and if there is internet connection, the splash screen should appear for 3 seconds and after that main activity should launch and if there is No internet turned on, then it should show "No internet connection " toast and open wireless networks settings and after enabling wifi, if return button is pressed, user should be brought back to splash screen... hope this is understandable.. but my code is not working as im getting bunch of errors which are

1.ACTION_WIRELESS_SETTINGS cannot be resolved or is not a field.
2.syntax error on token "{",{ expected after this token (in line public class SplashScreen extends Activity {) 3.syntax error on token "(",; expected and syntax error on token ")",; expected (in line protected void onCreate(Bundle savedInstanceState) {)

SplashScreen.java

public class SplashScreen extends Activity {
if (!NetworkCheckClass.haveNetworkConnection(SplashActivity.this)) {
    Toast.makeText(SplashScreen.this, "No internet connection!",             Toast.LENGTH_LONG).show();

    Intent intent=new Intent(Settings.ACTION_WIRELESS_SETTINGS);
    startActivity(intent);
}
else {
    // your code if connection is available
} // Splash screen timer
    private static int SPLASH_TIME_OUT = 3000;

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

        new Handler().postDelayed(new Runnable() {

            /*
             * Showing splash screen with a timer. This will be useful when you
             * want to show case your app logo / company
             */

            @Override
            public void run() {
                // This method will be executed once the timer is over
                // Start your app main activity
                Intent i = new Intent(SplashScreen.this, MainActivity.class);
                startActivity(i);

                // close this activity
                finish();
            }
        }, SPLASH_TIME_OUT);
    }
  }
  }

解决方案

Write below code in OnCreate() of your activity :

if (!NetworkCheckClass.haveNetworkConnection(SplashActivity.this)) {
Toast.makeText(SplashScreen.this, "No internet connection!",             Toast.LENGTH_LONG).show();

Intent intent=new Intent(Settings.ACTION_WIRELESS_SETTINGS);
startActivity(intent);
}
else {
 // your code if connection is available
} // Splash screen timer
