Android抢红包助手开发全攻略
背景:新年之际,微信微博支付宝红包是到处飞,但是,自己的手速总是比别人慢一点最后导致红包没抢到,红包助手就应运而生。
需求:收到红包的时候进行提醒,然后跳转到红包的界面方便用户。
思路:获取“读取通知信息”权限,然后开启服务监控系统通知,判断如果是微信红包就进行提醒(声音),然后跳转到红包所在的地方。
界面:
界面分为两部分,一部分是可以对App进行操作的,下面是一个可以滑动的界面,提示用户如何是软件正常工作,布局代码如下:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/root" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_marginTop="5dp" android:orientation="vertical" tools:context="com.fndroid.administrator.justforyou.MainActivity"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="3" android:text="打开提示音"/> <CheckBox android:id="@+id/isMusic" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="音量调节"/> <SeekBar android:id="@+id/seekbar" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_weight="1"/> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="3" android:text="有红包亮屏并解锁"/> <CheckBox android:id="@+id/isUnlock" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout> <Button android:id="@+id/setPermision" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="设置通知权限"/> <ScrollView android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:text="声明:"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="本软件为个人开发所得,只能对微信红包进行提醒。请合理使用本软件,使用不当造成的各种行为均与本人无关。软件使用过程不联网,不存在任何盗窃用户信息行为,请放心使用。"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:text="使用方法:"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="①如果未赋予软件读取通知权限,点击按钮“设置通知权限"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="②在本软件右侧勾选上,并确认提示信息"/> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitCenter" android:src="@drawable/inf"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="③关闭微信群的消息免打扰(取消图中的绿色按钮)"/> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/inf2"/> </LinearLayout> </ScrollView> </LinearLayout>
app打开的时候开启一个服务,编写一个NotificationListenerService的子类并实现onNotificationPosted和onNotificationRemoved方法,前面的方法会在收到通知的时候调用
// 编写一个NotificationListenerService的子类并实现onNotificationPosted和onNotificationRemoved方法 // 这两个方法在从SDK版本21的时候开始变成了非抽象,不重写则不能兼容21以下设备 public class NotificationService extends NotificationListenerService { private KeyguardManager.KeyguardLock kl; @Override public void onNotificationPosted(StatusBarNotification sbn) { // 主界面设置的信息保存在SharedPreferences中,在这里进行获取 SharedPreferences sharedPreferences = getSharedPreferences("userdata", MODE_PRIVATE); // 判断消息是否为微信红包 if (sbn.getNotification().tickerText.toString().contains("[微信红包]") && sbn.getPackageName ().equals("com.tencent.mm")) { // 读取设置信息,判断是否该点亮屏幕并解开锁屏,解锁的原理是把锁屏关闭掉 if (sharedPreferences.getBoolean("isUnlock",true)) { KeyguardManager km = (KeyguardManager) getSystemService(getApplicationContext() .KEYGUARD_SERVICE); kl = km.newKeyguardLock("unlock"); // 把系统锁屏暂时关闭 kl.disableKeyguard(); PowerManager pm = (PowerManager) getSystemService(getApplicationContext() .POWER_SERVICE); PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK, "bright"); wl.acquire(); wl.release(); } try { // 打开notification所对应的pendingintent sbn.getNotification().contentIntent.send(); } catch (PendingIntent.CanceledException e) { e.printStackTrace(); } // 判断是否该播放提示音 if (sharedPreferences.getBoolean("isMusic",true)){ MediaPlayer mediaPlayer = new MediaPlayer().create(this, R.raw.heihei); mediaPlayer.start(); } // 这里监听一下系统广播,判断如果屏幕熄灭就把系统锁屏还原 IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction("android.intent.action.SCREEN_OFF"); ScreenOffReceiver screenOffReceiver = new ScreenOffReceiver(); registerReceiver(screenOffReceiver, intentFilter); } } class ScreenOffReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (kl != null) { // 还原锁屏 kl.reenableKeyguard(); } } } @Override public void onNotificationRemoved(StatusBarNotification sbn) { super.onNotificationRemoved(sbn); } }
主的activity,注释在代码中了,就不详细说了
public class MainActivity extends AppCompatActivity implements CompoundButton .OnCheckedChangeListener, View.OnClickListener,SeekBar.OnSeekBarChangeListener { private LinearLayout root; private CheckBox isMusic; private CheckBox isUnlock; private SharedPreferences.Editor editor; private SharedPreferences sharedPreferences; private Button setPermision; private SeekBar seekBar; private AudioManager audioManager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // 获取控件实例 root = (LinearLayout) findViewById(R.id.root); isMusic = (CheckBox) findViewById(R.id.isMusic); isUnlock = (CheckBox) findViewById(R.id.isUnlock); setPermision = (Button) findViewById(R.id.setPermision); seekBar = (SeekBar) findViewById(R.id.seekbar); // 注册监听 isMusic.setOnCheckedChangeListener(this); isUnlock.setOnCheckedChangeListener(this); setPermision.setOnClickListener(this); seekBar.setOnSeekBarChangeListener(this); // 读取设置信息 sharedPreferences = getSharedPreferences("userdata", MODE_PRIVATE); editor = sharedPreferences.edit(); boolean music = sharedPreferences.getBoolean("isMusic", true); boolean unlock = sharedPreferences.getBoolean("isUnlock", true); isMusic.setChecked(music); isUnlock.setChecked(unlock); // 获得Audiomanager,控制系统音量 audioManager = (AudioManager) getSystemService(this.AUDIO_SERVICE); seekBar.setMax(audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC)); seekBar.setProgress(audioManager.getStreamVolume(AudioManager.STREAM_MUSIC)); // 监听系统媒体音量改变,并改变界面上的Seekbar的进度 IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction("android.media.VOLUME_CHANGED_ACTION"); VolumReceiver receiver = new VolumReceiver(); registerReceiver(receiver,intentFilter); // 开启服务 Intent intent = new Intent(MainActivity.this, NotificationService.class); startService(intent); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // 判断返回键点击,提示用户是否确认退出 if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) { Snackbar snackbar = Snackbar.make(root, "退出软件", Snackbar.LENGTH_LONG) .setAction("确认", new View.OnClickListener() { @Override public void onClick(View v) { MainActivity.this.finish(); } }); snackbar.show(); return true; } return super.onKeyDown(keyCode, event); } @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // checkbox的点击监听 switch (buttonView.getId()) { case R.id.isMusic: editor.putBoolean("isMusic", isChecked); editor.commit(); break; case R.id.isUnlock: editor.putBoolean("isUnlock", isChecked); editor.commit(); break; } } @Override public void onClick(View v) { switch (v.getId()){ case R.id.setPermision: // 打开系统里面的服务,方便用户直接赋予权限 Intent intent = new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS); startActivity(intent); break; } } @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { } @Override public void onStartTrackingTouch(SeekBar seekBar) { } @Override public void onStopTrackingTouch(SeekBar seekBar) { // seekbar的监听,滑动停止就修改系统媒体音量 audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,seekBar.getProgress(),0); } // 音量广播接收 class VolumReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { seekBar.setProgress(audioManager.getStreamVolume(AudioManager.STREAM_MUSIC)); } } }
Mainfest
<?xml version="1.0" encoding="utf-8"?> <manifest package="com.fndroid.administrator.justforyou" xmlns:android="http://schemas.android.com/apk/res/android"> <uses-permission android:name="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"/> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.DISABLE_KEYGUARD" /> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> <service android:name=".NotificationService" android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"> <intent-filter> <action android:name="android.service.notification.NotificationListenerService" /> </intent-filter> </service> </application> </manifest>
gradle添加依赖,因为用了Snackbar
dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:23.1.1' compile 'com.android.support:design:23.1.1' }
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
