在InputMethodService.java中，通过重写onComputeInsets方法并将outInsets.contentTopInsets设置为decor.getHeight()，可以防止键盘弹出时应用窗口上移。这种方法调整了contentTopInsets的值，以确保输入法窗口打开时不会影响应用界面的位置。

输入法弹出会导致应用窗口往上移动
InputMethodService.java中有关窗口重置代码
在这里插入图片描述
只需要重写onComputeInsets,将outInsets.contentTopInsets 设为decor.getHeight()

    @Override
    public void onComputeInsets(final InputMethodService.Insets outInsets) {
        super.onComputeInsets(outInsets);
        //解键盘顶起应用
        View decor = getWindow().getWindow().getDecorView();
        outInsets.contentTopInsets = decor.getHeight();
    }

源码中，关于contentTopInsets的说明：

    /**
     * Information about where interesting parts of the input method UI appear.
     */
    public static final class Insets {
        /**
         * This is the top part of the UI that is the main content.  It is
         * used to determine the basic space needed, to resize/pan the
         * application behind.  It is assumed that this inset does not
         * change very much, since any change will cause a full resize/pan
         * of the application behind.  This value is relative to the top edge
         * of the input method window.
         */
        public int contentTopInsets;
