    public static void openKeybord(EditText mEditText, Context mContext) {
        InputMethodManager imm = (InputMethodManager) mContext
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(mEditText, InputMethodManager.RESULT_SHOWN);
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,
                InputMethodManager.HIDE_IMPLICIT_ONLY);
    }

软键盘关闭

    public static void closeKeybord(EditText editText, Context context) {
        InputMethodManager imm = (InputMethodManager) context
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
    }

监听软键盘状态

    public static boolean isSoftInputShow(Activity activity) {
        if(activity.getWindow().getAttributes().softInputMode == WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE){
            return true;
        }else {
            return false;
        }
    }

解决表情和键盘切换时界面闪动

        设置默认时的弹出方式
        <activity
            android:name="MainActivity"
            android:windowSoftInputMode="adjustResize"/>

弹出表情时，设置软键盘弹出方式
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING);
mEmotionLayout.setVisibility(View.VISIBLE);

弹出键盘时，设置软键盘弹出方式
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
mEmotionLayout.setVisibility(View.GONE);
