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
