我可以通过以下代码接听电话：
public void answerPhoneHeadsethook(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
try {
if (isAccessibilitySettingsOn(mContext)) {
/**
* when talk-back is on
*/
} else {
/**
* when talk-back is off
*/
Process process = Runtime.getRuntime().exec("input keyevent " + Integer.toString(KeyEvent.KEYCODE_HEADSETHOOK));
Log.i("process error", "" + process.getOutputStream());
}
} catch (IOException e) {
// Runtime.exec(String) had an I/O problem, try to fall back
String enforcedPerm = "android.permission.CALL_PRIVILEGED";
Intent btnDown = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN,
KeyEvent.KEYCODE_HEADSETHOOK));
Intent btnUp = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,
KeyEvent.KEYCODE_HEADSETHOOK));
context.sendOrderedBroadcast(btnDown, enforcedPerm);
context.sendOrderedBroadcast(btnUp, enforcedPerm);
}
}
}
并且此代码成功运行。但是当对讲模式处于活动状态时，此代码不起作用。我想在对讲处于活动状态时接听电话。
