捕获Intent.ACTION_MEDIA_BUTTON事件

发布于 2024-12-03 23:21:00 字数 976 浏览 1 评论 0原文

我正在开发一个 Android 音频应用程序。现在，我正在捕捉并成功播放音频，我想添加一个新功能，通过蓝牙耳机捕获和播放。

我一直在阅读有关内容，似乎我必须管理 ACTION_MEDIA_BUTTON 事件：

Java文件：

....

public class audioBroadcastReceiver extends BroadcastReceiver 
{
    public void onReceive(Context context, Intent intent) 
    {
        if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) 
        {
            Log.d("","@@@@ WORKS" );
        }
        else
    {
    Log.d("","@@@@ ????" );                      
}
....

xml文件

....
<receiver android:name="audioBroadcastReceiver">
    <intent-filter>     
        <action android:name="android.intent.action.MEDIA_BUTTON">
        </action>
    </intent-filter>
</receiver>
<uses-permission android:name="android.permission.BLUETOOTH" />

但是什么也没发生，所以，有人可能会给我一个例子或想法：

1°知道蓝牙何时连接。

2° 通过蓝牙耳机路由音频数据包。

谢谢！

I'm developing a Android audio application. Now, I'm capturing
and playing audio with sucess and I want to add a new feature, the capture and playing through bluetooh headset.

I have been reading about that, and seems that I must manage the ACTION_MEDIA_BUTTON
event:

Java file:

....

public class audioBroadcastReceiver extends BroadcastReceiver 
{
    public void onReceive(Context context, Intent intent) 
    {
        if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) 
        {
            Log.d("","@@@@ WORKS" );
        }
        else
    {
    Log.d("","@@@@ ????" );                      
}
....

xml file

....
<receiver android:name="audioBroadcastReceiver">
    <intent-filter>     
        <action android:name="android.intent.action.MEDIA_BUTTON">
        </action>
    </intent-filter>
</receiver>
<uses-permission android:name="android.permission.BLUETOOTH" />

But nothing happens, so, somebody may give me a example or a idea for:

1º Know when the bluetooh has been connected.

2º Routed the audio packets through bluetooh headset.

Thanks!

您需要 bluetoothAdapter 方法。
蓝牙适配器 blueT = 蓝牙适配器.getDefaultAdapter();

// create broadcast receiver
BroadcastReceiver blueReceiver = new BroadcastReceiver(){
// todo switch states to turn on or off or check is on
// check is on is something like this:
case (blueT.STATE_ON) : {
 // do something with it
}

if(blueT.isEnabled()){
do something
}

You need the bluetoothAdapter method.
BluetoothAdapter blueT = BluetoothAdapter.getDefaulAdapter();

// create broadcast receiver
BroadcastReceiver blueReceiver = new BroadcastReceiver(){
// todo switch states to turn on or off or check is on
// check is on is something like this:
case (blueT.STATE_ON) : {
 // do something with it
}

if(blueT.isEnabled()){
do something
}
