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
