1.软键盘覆盖输入框

【解决】

1.1AndroidManifest.xml

1.2 添加类（该类是独立类）

/** * 时间： 2016/7/21 11:50 * ---ZWQ--- */public class AndroidBug5497Workaround {    private static final String TAG = "AndroidBug5497Workaround";    // For more information, see https://code.google.com/p/android/issues/detail?id=5497    // 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 Activity activity;    private FrameLayout.LayoutParams frameLayoutParams;    private View mChildOfContent;    private int usableHeightPrevious;    private int statusBarHeight;//状态栏高度    private AndroidBug5497Workaround(Activity activity) {        this.activity = activity;        FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);        mChildOfContent = content.getChildAt(0);        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {            public void onGlobalLayout() {//全局视图                possiblyResizeChildOfContent();            }        });        frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();    }    /**可能调整内容的子内容*/    private void possiblyResizeChildOfContent() {        //获得有效高度        int usableHeightNow = computeUsableHeight();        LogUtils.v(TAG,"有效高度："+usableHeightNow);        if (usableHeightNow != usableHeightPrevious) {            int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();            LogUtils.v(TAG,"全屏高度："+usableHeightSansKeyboard);            //这个判断是为了解决19之前的版本不支持沉浸式状态栏导致布局显示不完全的问题(使用沉浸式状态栏时使用改判断)//            if(Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT){//                Rect frame = new Rect();//                activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);//                int statusBarHeight = frame.top;//                usableHeightSansKeyboard -= statusBarHeight;//            }            int heightDifference = usableHeightSansKeyboard - usableHeightNow;            LogUtils.v(TAG, "默认高度：" + heightDifference);            if (heightDifference > (usableHeightSansKeyboard/4)) {                // keyboard probably just became visible（键盘可能是可见的）                frameLayoutParams.height = usableHeightNow;            } else {                // keyboard probably just became hidden（键盘可能是隐藏的）                frameLayoutParams.height = usableHeightSansKeyboard-statusBarHeight;            }            mChildOfContent.requestLayout();//重新设置自己位置            usableHeightPrevious = usableHeightNow;        }    }    /**计算有效高度*/    private int computeUsableHeight() {        Rect r = new Rect();        mChildOfContent.getWindowVisibleDisplayFrame(r);        statusBarHeight = r.top;        LogUtils.v(TAG,"状态栏高度："+statusBarHeight);        LogUtils.v(TAG,"我的布局高度（包含状态栏）："+r.bottom);//从顶到加载布局控件底部距离       /* 这个判断是为了解决19之后的版本在弹出软键盘时，          键盘和推上去的布局（adjustResize）之间有黑色区域的问题          使用沉浸式状态栏时使用改判断（未检验用时调节）*///        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){//            return (r.bottom - r.top)+statusBarHeight;//        }        return (r.bottom - r.top);    }}

1.3 调用上面类-加载布局页面-加载布局方法

    @Override    public void setRootView() {        super.setRootView();        setContentView(R.layout.activity_find_details);        AndroidBug5497Workaround.assistActivity(this);//防止软件盘遮挡网页输入框内容        context = this;    }

1.4完成
