【Android】通过耳机调起语音助手App配置

一、AndroidManifest.xml 配置：

<activity-alias            android:name="包名"            android:icon="@mipmap/ic_launcher"            android:label="测试语音"            android:targetActivity="调起界面">            <intent-filter>                <action android:name="android.intent.action.ASSIST" />                <action android:name="android.intent.action.VOICE_COMMAND" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.VOICE_LAUNCH" />            intent-filter>        activity-alias>

二、配置广播

<receiver android:name=".MediaButtonReceiver">            <intent-filter>                <action android:name="android.intent.action.MEDIA_BUTTON" />                <action android:name="android.media.AUDIO.BECOMING_NOISY" />            intent-filter>        receiver>

三、广播

public class MediaButtonReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) {            KeyEvent keyEvent = intent.getParcelableExtra("android.intent.extra.KEY_EVENT");            if (keyEvent != null) {                LogUtil.i("keyEvent _ keyevent --> :" + keyEvent.toString());                int keyCode = keyEvent.getKeyCode();                LogUtil.i("keyCode __ : " + keyCode);                switch (keyCode) {                    case KeyEvent.KEYCODE_MEDIA_PAUSE:                        break;                    case KeyEvent.KEYCODE_MEDIA_PLAY:                        break;                    case KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE:                        break;                    case KeyEvent.KEYCODE_HEADSETHOOK:                        break;                }            }        }    }}

四、注册广播成为唯一（小米不适用）

ComponentName componentName;AudioManager manager;@Override    public void onCreate() {        super.onCreate();        manager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);        componentName = new ComponentName(getPackageName(), MediaButtonReceiver.class.getName());        manager.registerMediaButtonEventReceiver(componentName);        manager.setBluetoothScoOn(true);        manager.startBluetoothSco();    }@Override    public void onDestroy() {        manager.setBluetoothScoOn(false);        manager.stopBluetoothSco();        manager.unregisterMediaButtonEventReceiver(componentName);        super.onDestroy();    }
