SystemUI 鎖屏來電界面點擊Home鍵無作用

不積跬步無以至千里

一.前摘

        其實這裏是原生的設計，故意在鎖屏的來電界面，不讓執行home鍵的流程（這裏應該是啓動launcher的主activity），因此這裏我們要針對它的邏輯進行修改。

二.修改

代碼路徑：

app/src/com/android/systemui/statusbar/phone/NavigationBarFragment.java

private boolean onHomeTouch(View v, MotionEvent event) {
        if (mHomeBlockedThisTouch && event.getActionMasked() != MotionEvent.ACTION_DOWN) {
            return true;
        }
        // If an incoming call is ringing, HOME is totally disabled.
        // (The user is already on the InCallUI at this point,
        // and his ONLY options are to answer or reject the call.)
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                mHomeBlockedThisTouch = false;
//修改的地方爲把關於判斷此時是否爲處於接打電話，把這塊邏輯去掉，就可以了
//                TelecomManager telecomManager =
//                        getContext().getSystemService(TelecomManager.class);
//
