android闹铃简单实现
1.闹铃activity
http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Button android:id="@+id/setTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="设置时间"/>
<Button android:id="@+id/setRing"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/setTime"
android:text="设置铃声"/>
<Button android:id="@+id/setOver"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/setRing"
android:text="设置完成"/>
</RelativeLayout>
3.广播接收闹铃信息：
package com.example.myalarm;
import java.io.IOException;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;
import android.util.Log;
import android.widget.Toast;
public class AlarmBroadcastReceiver extends BroadcastReceiver {
Uri ringUri;
@Override
public void onReceive(Context context, Intent intent) {
String msg = intent.getStringExtra("msg");
Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();
MediaPlayer mp = new MediaPlayer();
String uri = intent.getStringExtra("ringURI");
if (uri!=null) {
ringUri = Uri.parse(uri);
Log.d("AlarmActivity", ringUri.toString());
}
try {
mp.setDataSource(context, ringUri);
mp.prepare();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mp.start();
}
}
4.在manifest文件中注册广播
<receiver android:name="com.example.myalarm.AlarmBroadcastReceiver"></receiver>
以上代码就是实现Android闹钟的全部代码了，希望大家能够喜欢。
