我的要求是在启动拨出电话时打开免提电话。我尝试了以下代码,但它无法正常工作。事实上,扬声器电话在通话过程中打开,第二个电话来了!
package in.co.allsolutions;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
//import android.view.View;
import android.widget.Toast;
import android.media.AudioManager;
public class MyTelephonyBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setSpeakerphoneOn(true);
Bundle extras = intent.getExtras();
if (extras != null) {
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Log.i("AS", "Message Received. State = " + state + ", Mode = " + audioManager.getMode());
//audioManager.setMode(AudioManager.MODE_NORMAL);
//audioManager.setSpeakerphoneOn(true);
// if (state.equals("OFFHOOK"))
// {
//audioManager.setMode(AudioManager.MODE_CURRENT);
//audioManager.setSpeakerphoneOn(true);
//audioManager.setMode(AudioManager.MODE_IN_CALL);
//audioManager.setSpeakerphoneOn(true);
//audioManager.setMode(AudioManager.MODE_RINGTONE);
//audioManager.setSpeakerphoneOn(true);
if (audioManager.isSpeakerphoneOn()) {
Log.i("AS", "Speaker on - SUCCESS.");
} else {
Log.i("AS", "Speaker could not be turned on.");
}
// }
} else {
Toast.makeText(context, "Message Received without any state", Toast.LENGTH_LONG).show();
}
}
}
感谢。

您可以通过以下编程方式进行设置:
AudioManager audioManager = (AudioManager)getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
audioManager.setMode(AudioManager.MODE_IN_CALL);
audioManager.setSpeakerphoneOn(true);
但是,请记住,在停止通话时不要忘记关闭扬声器:
audioManager.setSpeakerphoneOn(false);
并且,在清单中设置权限:
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
这段代码对我来说很好。这对你有帮助。

提出了类似问题并回答了here.
我认为答案可能在您项目的AndroidManifest.xml中。尝试添加:
uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"
到你的清单,这将允许你的应用修改设备的音频设置 您还需要将audioManager模式更改为MODE_IN_CALL:
audioManager.setMode(AudioManager.MODE_IN_CALL)
