【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();
	    }
