Android软键盘挡住输入框

最近遇到了软键盘挡住输入框的问题，上网搜罗半天，找到了一篇针对这个问题讲的比较全（好）的文章，地址放在下面：https://www.diycode.cc/topics/383

自己的收获:

普通Activity（不带WebView），直接在manifest文件中对activity设置：android:windowSoftInputMode的值adjustPan或者adjustResize即可；
如果带WebView：
- 如果非全屏模式，可以使用adjustResize；
- 如果是全屏模式，则使用AndroidBug5497Workaround进行处理。

注：

1、这里的全屏模式即是页面是全屏的，包括Application或activity使用了Fullscreen主题、使用了『状态色着色』、『沉浸式状态栏』、『Immersive Mode』等等——总之，基本上只要是App自己接管了状态栏的控制，就会产生这种问题。

2、AndroidBug5497Workaround的使用：

把AndroidBug5497Workaround类复制到项目中；
在需要填坑的activity的setContentView()语句后，添加一句AndroidBug5497Workaround.assistActivity(this)即可。

class AndroidBug5497Workaround {    // 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 AndroidBug5497Workaround(activity);    }    private View mChildOfContent;    private int usableHeightPrevious;    private FrameLayout.LayoutParams frameLayoutParams;    private AndroidBug5497Workaround(Activity activity) {        FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);        mChildOfContent = content.getChildAt(0);        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {            public void onGlobalLayout() {                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 / 4)) {                // 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);    }}
