Android判断手机是否联网及自动跳转功能(收藏版)

android欢迎页自动跳转及手机网络检测，具体实现代码如下所示：

在1.2s后从欢迎页（welcome）跳转到登陆页（Login_Activity），并进行手机网络检测

package com.example.amusic.welcome;
import android.content.Intent;
import android.content.IntentFilter;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.example.amusic.monitor.NetworkChangeReceiver;
import com.example.amusic.R;
import java.util.Timer;
import java.util.TimerTask;
public class welcome extends AppCompatActivity {
 private final int SKIP_DELAY_TIME = 1200;
 private NetworkChangeReceiver networkChangeReceiver;
 private IntentFilter intentFilter;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_welcome);
   //手机网络检测
   intentFilter = new IntentFilter();
   intentFilter.addAction("android.net.conn.CONNECTIVITY_CHANGE");
   networkChangeReceiver = new NetworkChangeReceiver();
   registerReceiver ( networkChangeReceiver, intentFilter);
   Timer time = new Timer();
   TimerTask task = new TimerTask(){
     @Override
     public void run() {
       startActivity(new Intent(welcome.this,Login_Activity.class));
       finish();
       //onDestroy();
     }
   };
   time.schedule(task, SKIP_DELAY_TIME);
 }
 protected void onDestroy(){
   super.onDestroy();
   unregisterReceiver( networkChangeReceiver);
 }
}
// An highlighted block
var foo = 'bar';

public class NetworkChangeReceiver extends BroadcastReceiver {
 @Override
 public void onReceive(Context context, Intent intent) {
   ConnectivityManager connectivityManager = (ConnectivityManager)
       context.getSystemService(Context.CONNECTIVITY_SERVICE);
   NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
   if (networkInfo!= null&&networkInfo.isAvailable()) {
     Toast.makeText(context, "手机网络已开启！", Toast.LENGTH_SHORT).show();
   } else {
     Toast.makeText(context, "手机网络未开启！", Toast.LENGTH_SHORT).show();
   }

}

}
// An highlighted block
var foo = 'bar';

运行结果
