android直接挂断电话

2015年1月29日 · 1023 字 · 5 分钟

最近在写一个用来发短信的机器人(android),当然需要屏蔽所有来电了。多的话不说了,直接看步骤。(IDE为android studio): 1.在 src/main下新建 aidl 目录。

2.在src/main/aidl下新建包 com.android.internal.telephony。

3.在com.android.internal.telephony新建文件 ITelephony.aidl,内容如下:

4.android studio 菜单 Build->Rebuild project

5.在Activity中注册监听(写在onCreate())

TelephonyManager mTelephonyManager = (TelephonyManager) this
                .getSystemService(TELEPHONY_SERVICE);
        mTelephonyManager.listen(phoneStateListener,
                PhoneStateListener.LISTEN_CALL_STATE);

6.在Activity中新建以下方法以获得telephony的实例

/**
     * @param context
     * @return
     */
    private static ITelephony getITelephony(Context context) {
        TelephonyManager mTelephonyManager = (TelephonyManager) context
                .getSystemService(TELEPHONY_SERVICE);
        Class c = TelephonyManager.class;
        Method getITelephonyMethod = null;
        try {
            getITelephonyMethod = c.getDeclaredMethod("getITelephony",
                    (Class[]) null); // 获取声明的方法
            getITelephonyMethod.setAccessible(true);
        } catch (SecurityException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }

        try {
            ITelephony iTelephony = (ITelephony) getITelephonyMethod.invoke(
                    mTelephonyManager, (Object[]) null); // 获取实例
            return iTelephony;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

7.在activity类中建立内部类

PhoneStateListener phoneStateListener = new PhoneStateListener() {

        @Override
        public void onCallStateChanged(int state, String incomingNumber) {

            ITelephony iTelephony = getITelephony(MainActivity.this);
            switch (state) {
                case TelephonyManager.CALL_STATE_RINGING:
                    iTelephony = getITelephony(getApplicationContext()); //获取电话接口
                    if (iTelephony != null) {
                        try {
                            iTelephony.endCall(); // 挂断电话
                            Message msg = new Message();
                            msg.what = SYS_MSG;
                            msg.obj ="成功挂断["+incomingNumber+"]的电话";
                            handler.sendMessage(msg);
                        } catch (RemoteException e) {
                            Message msg = new Message();
                            msg.what = SYS_MSG;
                            msg.obj ="挂断["+incomingNumber+"]的电话失败";
                            handler.sendMessage(msg);
                        }
                    }
                    break;
                default:
                    break;
            }
        }

    };
