Android中监听软键盘弹出收起以及隐藏软键盘，显示软键盘

Android中使用EditText会牵扯到软键盘，没少踩坑，今天总结一下

1，Android中阻止activity弹出软键盘

android:windowSoftInputMode="stateAlwaysHidden|stateHidden"

2，隐藏软键盘

/**
     * 隐藏键盘
     */
    protected void hideInput() {
   
   
        InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
        View v = getWindow().peekDecorView();
        if (null != v) {
   
   
            imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
        }
    }

3，显示软键盘

getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

4，监听软键盘弹出还是收起

public class SoftKeyboardStateHelper implements ViewTreeObserver.OnGlobalLayoutListener {
   
   

    public interface SoftKeyboardStateListener {
