Question

我在这里尝试拨打电话，但是问题是当我完成通话时，我没有回到我的视图。在通话清单中保持堆栈...当我点击按钮时回到我的手机，它回到我想要展示的活动......谢谢:)

@Override
public void onClick(View arg0) {

    if (arg0 == btn_ajout) {
         Intent i=new Intent(Docteur_gestion.this, AjoutDocActivity.class);
         startActivity(i);
    }

    if(arg0 == btn_appel) {
         Intent callIntent = new Intent(Intent.ACTION_CALL);
         callIntent.setData(Uri.parse("tel:"+global_txt_tel_doc));
         startActivity(callIntent);       
    }
}

您需要按如下方式实施phoneStateListener：

public class MainActivity extends Activity {

    final Context context = this;
    private Button button;

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        button = (Button) findViewById(R.id.buttonCall);

        // add PhoneStateListener
        PhoneCallListener phoneListener = new PhoneCallListener();
        TelephonyManager telephonyManager = (TelephonyManager) this
            .getSystemService(Context.TELEPHONY_SERVICE);
        telephonyManager.listen(phoneListener,PhoneStateListener.LISTEN_CALL_STATE);

        // add button listener
        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:0377778888"));
                startActivity(callIntent);

            }

        });

    }

    //monitor phone call activities
    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;
                }

            }
        }
    }

}

清单中需要两个权限

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

和

<uses-permission android:name="android.permission.CALL_PHONE" />
