當(dāng)軟鍵盤出現(xiàn)遮擋住布局后，如果修改成SOFT_INPUT_ADJUST_PAN或SOFT_INPUT_ADJUST_RESIZE依然解決不了想要的需求，那么下面這個(gè)就是最合適解決軟鍵盤擋住的方案了。
解決方案大概要述：把布局修改成滑動(dòng)式布局，當(dāng)出現(xiàn)軟鍵盤后，將最外面的布局高度縮至軟鍵盤上面，并且整體布局依然可以保持滑動(dòng)。

對本身代碼侵略性也少，一句代碼放在Activity即可。

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ```
        Softkeyboard.assistActivity(rlContent);
        ```
    }

Softkeyboard

public class Softkeyboard {

    // For more information, see https://issuetracker.google.com/issues/36911528
    // To use this class, simply invoke assistActivity() on an Activity that already has its content view set.

    public static void assistActivity(Activity activity) {
        new Softkeyboard(activity);
    }

    public static void assistActivity(RelativeLayout rlContent) {
        new Softkeyboard(rlContent);
    }

    private View mChildOfContent;
    private int usableHeightPrevious;
    private FrameLayout.LayoutParams frameLayoutParams;

    private Softkeyboard(Activity activity) {
        FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);
        mChildOfContent = content.getChildAt(0);
        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(() -> possiblyResizeChildOfContent());
        frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();
    }

    private Softkeyboard(RelativeLayout rlContent) {
        mChildOfContent = rlContent;
        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(() -> possiblyResizeChildOfContent());
        frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();
    }

    private void possiblyResizeChildOfContent() {
        int usableHeightNow = computeUsableHeight();
        if (usableHeightNow != usableHeightPrevious) {
            int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();
            int heightDifference = usableHeightSansKeyboard - usableHeightNow;
            if (heightDifference > (usableHeightSansKeyboard / 5)) {
                // keyboard probably just became visible
                frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
            } else {
                // keyboard probably just became hidden
                frameLayoutParams.height = usableHeightSansKeyboard;
            }
            mChildOfContent.requestLayout();
            usableHeightPrevious = usableHeightNow;
        }
    }

    private int computeUsableHeight() {
        Rect r = new Rect();
        mChildOfContent.getWindowVisibleDisplayFrame(r);
        return (r.bottom - r.top);
    }

}

在這里對Softkeyboard的一段代碼usableHeightSansKeyboard / 5說一下，如果包含導(dǎo)航欄也加入滑動(dòng)布局的話，就 usableHeightSansKeyboard / 4
