我正在创建一个调用它的android应用程序。我只是想在一段时间后放弃或取消一个电话,就像我想打一个电话,它会在60秒后自动掉线。这在Android中是否可行?这是我的代码:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// add PhoneStateListener
PhoneCallListener phoneListener = new PhoneCallListener();
TelephonyManager telephonyManager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:*03362111904"));
startActivity(callIntent);
}
private class PhoneCallListener extends PhoneStateListener {
private boolean isPhoneCalling = false;
String LOG_TAG = "LOGGING 123";
@Override
public void onCallStateChanged(int state, String incomingNumber) {
if (TelephonyManager.CALL_STATE_RINGING == state) {
// phone ringing
Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
}
if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
// active
Log.i(LOG_TAG, "OFFHOOK");
isPhoneCalling = true;
}
if (TelephonyManager.CALL_STATE_IDLE == state) {
// run when class initial and phone call ended, need detect flag
// from CALL_STATE_OFFHOOK
Log.i(LOG_TAG, "IDLE");
if (isPhoneCalling) {
Log.i(LOG_TAG, "restart app");
// restart app
Intent i = getBaseContext().getPackageManager()
.getLaunchIntentForPackage(
getBaseContext().getPackageName());
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
isPhoneCalling = false;
}
}
}
}
}
答案 0 :(得分:1)
已经提到在BroadcastReceiver
中捕获拨出电话,如果您想在拨号前结束通话,这绝对是最好的方式。
到目前为止我遇到的唯一挂断方式是通过Java Reflection这样做。由于它不是公共API的一部分,因此您应该小心使用它,而不是依赖它。对Android内部组成的任何更改都将有效地破坏您的应用程序。
Prasanta Paul's blog demonstrates如何实现,我在下面进行了总结。
获取ITelephony
对象:
TelephonyManager tm = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
try {
// Java reflection to gain access to TelephonyManager's
// ITelephony getter
Log.v(TAG, "Get getTeleService...");
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
com.android.internal.telephony.ITelephony telephonyService =
(ITelephony) m.invoke(tm);
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG,
"FATAL ERROR: could not connect to telephony subsystem");
Log.e(TAG, "Exception object: " + e);
}
结束通话:
telephonyService.endCall();
