EditText Rewriting for pjsip Video Communication Development (upper-layer applications)

We often use the mobile phone call function. When we press the keyboard, there is a place where the content of our buttons is displayed. When our hands click that place, the software disk is not displayed, so when we have a digital keyboard, We need to block the system's software disk. Let's analyze the conditions for the software disk to pop up: 1. Focus. When EditText is in focus, the software disk will pop up automatically, so we need to rewrite the onFocusChanged function 2. Touch time, when you click EditText, it will be in the focus, so we need to rewrite the onTouchEvent function 3. When the layout changes, EditText will also be in the focus, so we should also rewrite the layout function.
