Android弹出拨号界面和拨打电话实现（转）

需要使用反射机制将ITelephony反射出来进行操作。

private void dial(String number) {
        Class<TelephonyManager> c = TelephonyManager.class;
        Method getITelephonyMethod = null;
        try {
            getITelephonyMethod = c.getDeclaredMethod("getITelephony",
                    (Class[]) null);
            getITelephonyMethod.setAccessible(true);
        } catch (SecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        try {
            TelephonyManager tManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
            Object iTelephony;
            iTelephony = (Object) getITelephonyMethod.invoke(tManager,(Object[]) null);
            Method dial = iTelephony.getClass().getDeclaredMethod("dial", String.class);
            dial.invoke(iTelephony, number);
        } catch (IllegalArgumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    
    private void call(String number) {

        try {

                    (Class[]) null);
            getITelephonyMethod.setAccessible(true);
        } catch (SecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        try {
            TelephonyManager tManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
            Object iTelephony;
            iTelephony = (Object) getITelephonyMethod.invoke(tManager,(Object[]) null);
            Method dial = iTelephony.getClass().getDeclaredMethod("call", String.class);
            dial.invoke(iTelephony, number);
