我怎样才能运行一段代码,比方说,每1秒???
这是我的代码片段:
主要活动:
private Context ctx;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button)findViewById(R.id.button1);
ctx = this;
btn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar cal = Calendar.getInstance();
int inter = 1000;
Intent i = new Intent(ctx, Brodcast.class);
PendingIntent pi = PendingIntent.getBroadcast(ctx, 0, i, 0);
am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), inter, pi);
}
});
}
广播级:
public class Brodcast extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
Toast.makeText(arg0, "This wil appear every one seconde", Toast.LENGTH_LONG).show();
Log.e("this will apear every one seconde" , "this will apear every one seconde");
}
}
但是没有显示日志或Toast的原因???请帮忙。
最佳答案
请确保已在清单文件中定义了广播接收器,或使用注释中建议的代码注册了该接收器。
