问题描述
我想使用与broadcasReceiver报警马槽里。我尝试在教程红粉使用例如:系统服务和广播接收器。但是当我的时间结束后运行的例子,我还没有,我想展现的敬酒。
:在code是由以下code给出我的主要活动:
公共类AlarmActivity延伸活动{
/ **当第一次创建活动调用。 * / @覆盖
公共无效的onCreate(捆绑savedInstanceState){
super.onCreate(savedInstanceState);
的setContentView(R.layout.activity_alarm);
} 公共无效startAlert(查看视图){
文字的EditText =(EditText上)findViewById(R.id.time);
INT I =的Integer.parseInt(text.getText()的toString());
意向意图=新意图(这一点,MyBroadcastReceiver.class);
的PendingIntent的PendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(),234324243,意向,0);
AlarmManager alarmManager =(AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP,System.currentTimeMillis的()
+(I * 1000)的PendingIntent);
Toast.makeText(这一点,报警设置中的+ I +秒
Toast.LENGTH_LONG).show();
}
}
我的广播接收器:
公共类MyBroadcastReceiver扩展广播接收器{
公共无效的onReceive(上下文的背景下,意图意图){
Toast.makeText(背景下,不要panik但你的时间到了!!!!
Toast.LENGTH_LONG).show();
//震动移动电话
振动器振动=(振动器)context.getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(2000);
}}
我的主要Laout:
<?XML版本=1.0编码=UTF-8&GT?;
< LinearLayout中的xmlns:机器人=http://schemas.android.com/apk/res/android

解决方案
接收器必须从广播接收器延长
公共类MyBroadcastReceiver扩展广播接收器{
// ...
}
另外要确保清单文件接收器名称是正确的。
I am trying to use an alarm manger with broadcasReceiver. I try to use the example gived in Tutorial: System Services and BroadcastReceiver . but when I run the example after the end of the time I haven't the toast that i would like to show. the code is given by the code below:
My main Activity:
public class AlarmActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_alarm);
}
public void startAlert(View view) {
EditText text = (EditText) findViewById(R.id.time);
int i = Integer.parseInt(text.getText().toString());
Intent intent = new Intent(this, MyBroadcastReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 234324243, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
+ (i * 1000), pendingIntent);
Toast.makeText(this, "Alarm set in " + i + " seconds",
Toast.LENGTH_LONG).show();
}
}
my broadCastReceiver:
public class MyBroadcastReceiver extends BroadcastReceiver{
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Don't panik but your time is up!!!!.",
Toast.LENGTH_LONG).show();
// Vibrate the mobile phone
Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(2000);
}
}
my main Laout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<EditText
android:id="@+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Number of seconds"
android:inputType="numberDecimal" >
</EditText>
<Button
android:id="@+id/ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="startAlert"
android:text="Start Counter" >
</Button>
</LinearLayout>
and the manifestfile:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.broadcastreceiver"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.VIBRATE" >
</uses-permission>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.broadcastreceiver.AlarmActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".MyBroadcastReceiver" >
</receiver>
</application>
</manifest>
解决方案
The receiver must extend from BroadcastReceiver
public class MyBroadcastReceiver extends BroadcastReceiver {
// ...
}
Also be sure that receiver name in manifest file is correct.
