1.开启沉浸式状态栏后，输入法弹出异常，adjustResize失效（api<21时出现）

解决办法 – 原文地址：stackflow

//在要弹出的根布局中添加
android:fitsSystemWindows="true"
//然后界面高度就不正常了（出现了空白高度，估计是预留的状态栏高度）；
//咱们可以重写Layout的fitSystemWindows的方法来解决此问题
//然后api20又出问题了，还需要重写windowinsetsonapplywindowinsets方法 。。。
//具体复写的类如下
public class MyResizeLinearLayout extends LinearLayout{
     private int[] mInsets = new int[4];
     public MyResizeLinearLayout(Context context) {
         super(context);
     }
     public MyResizeLinearLayout(Context context, AttributeSet attrs) {
         super(context, attrs);
     }
     public MyResizeLinearLayout(Context context, AttributeSet attrs, int defStyleAttr) {
         super(context, attrs, defStyleAttr);
     }
     @TargetApi(Build.VERSION_CODES.LOLLIPOP)
     public MyResizeLinearLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
         super(context, attrs, defStyleAttr, defStyleRes);
     }
     @Override
     protected final boolean fitSystemWindows(Rect insets) {
         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
             mInsets[0] = insets.left;
             mInsets[1] = insets.top;
             mInsets[2] = insets.right;
             insets.left = 0;
             insets.top = 0;
             insets.right = 0;
         }
         return super.fitSystemWindows(insets);
     }
     @Override
     public final WindowInsets onApplyWindowInsets(WindowInsets insets) {
         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
             mInsets[0] = insets.getSystemWindowInsetLeft();
             mInsets[1] = insets.getSystemWindowInsetTop();
             mInsets[2] = insets.getSystemWindowInsetRight();
             return super.onApplyWindowInsets(insets.replaceSystemWindowInsets(0, 0, 0,
                     insets.getSystemWindowInsetBottom()));
         } else {
             return insets;
         }
     }
}

2.ScrollView 嵌套ListView或RecycleView 后 高度仅有一行数据的高度

分析原因：ScrollView 无法预估ListView 的高度，所以高度为item的高度
解决方法 ： 手动计算高度

    private void refreshHight() {
        int totalHeight = 0;
        for (int i = 0, len = lvListPay.getCount(); i < len; i++) {
            View listItem = adapter.getView(i, null, lvListPay);
            listItem.measure(0, 0);
            totalHeight += listItem.getMeasuredHeight();
        }

        ViewGroup.LayoutParams params = lvListPay.getLayoutParams();
        params.height = totalHeight + (lvListPay.getDividerHeight() * (adapter.getCount() - 1));
        lvListPay.setLayoutParams(params);
    }

当item高度固定可以使用下面的算法优化

 private void refreshHight() {
        int totalHeight = 0;

        View listItem = adapter.getView(0, null, lvListPay);
        listItem.measure(0, 0);
        totalHeight = listItem.getMeasuredHeight() * lvListPay.getCount();

        ViewGroup.LayoutParams params = lvListPay.getLayoutParams();
        params.height = totalHeight + (lvListPay.getDividerHeight() * (adapter.getCount() - 1));
        lvListPay.setLayoutParams(params);
    }
