android 开机自启动程序2

android开机启动service，适合闹钟程序实例中一共三个类

1．public class YourReceiver extends BroadcastReceiver

2．public class ServiceTest extends Service

3．public class ShowActivity extends Activity

1．yourReceiver 类：

package radar.com; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class YourReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Intent i = new Intent(context, ServiceTest.class); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startService(i); } }

2．复制代码ServiceTest 类：

package radar.com; import java.util.Calendar; import android.app.Service; import android.content.Intent; import android.os.Handler; import android.os.IBinder; import android.util.Log; public class ServiceTest extends Service{ Handler hd1=new Handler(); /**启动activity的开关*/ boolean b; /**启动一次activity之后的一分钟内将不再重新启动*/ int time; public static final Intent ACTION_START = null; private static final String TAG = "TestService"; @Override public IBinder onBind(Intent intent) { return null; } @Override public boolean onUnbind(Intent i) { Log.e(TAG, "============> TestService.onUnbind"); return false; } @Override public void onRebind(Intent i) { Log.e(TAG, "============> TestService.onRebind"); } @Override public void onCreate() { Log.e(TAG, "============> TestService.onCreate"); hd1.postDelayed(mTasks, delay); } @Override public void onStart(Intent intent, int startId) { Log.e(TAG, "============> TestService.onStart"); } @Override public void onDestroy() { Log.e(TAG, "============> TestService.onDestroy"); } public void log(){ Calendar c= Calendar.getInstance(); int h=c.getTime().getHours(); int m=c.getTime().getMinutes(); Log.i("hour", ""+h); Log.i("minute", ""+m); /**这里的16和10可以自己定义一下主要是提醒的时间设置，我不想做的太繁琐，所有没有些闹钟，只是用这个测试一下:)*/ if(h==16&&m==10) { /**为防止持续调用，所以用boolean 变量b做了一个小开关*/ if(!b){ Intent i = new Intent(); i.setClass(ServiceTest.this, ShowActivity.class); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); this.startActivity(i); this.stopSelf(); b=true; } } /**开关开启后计时60秒，在这60秒之内就不再重新启动activity了，而60秒一过，上面的h和m条件肯定就不成立了*/ if(b){ time+=5; if(time==60){ time=0; b=false; } } } /** 速度控制参数(单位豪秒) */ private int delay = 5000; /** * 控制速度 * */ private Runnable mTasks = new Runnable() { public void run() { log(); hd1.postDelayed(mTasks, delay); } }; }

3．复制代码showActivity 类：（.此类中啥都没有，就是演示一下activity可以被启动）

package radar.com; import radar.com.R; import android.app.Activity; import android.os.Bundle; import android.view.Window; import android.view.WindowManager; public class ShowActivity extends Activity{ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main); } }

4．复制代码下面是很重要的AndroidManifest

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="radar.com" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <service android:name=".ServiceTest" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </service> <receiver android:name=".yourReceiver" > <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <category android:name="android.intent.category.HOME"/> </intent-filter> </receiver> <activity android:name=".showActivity" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden|navigation" android:screenOrientation="portrait"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="4" /> </manifest>

既可以作为开机启动并隐藏到后台的service，也可以当做activity打开
