Android(安卓)WebView 禁止输入

开发过程中，有时需要显示以前输入的数据，且不能修改。搜了网上有重写WebView的onTouchEvent方法，直接return false，但测试WebView将不能响应滚动事件。

后来查看文档，找到如下方法：

/**     * Set the descendant focusability of this view group. This defines the relationship     * between this view group and its descendants when looking for a view to     * take focus in {@link #requestFocus(int, android.graphics.Rect)}.     *     * @param focusability one of {@link #FOCUS_BEFORE_DESCENDANTS}, {@link #FOCUS_AFTER_DESCENDANTS},     *   {@link #FOCUS_BLOCK_DESCENDANTS}.     */    public void setDescendantFocusability(int focusability)

/**     * This view will get focus before any of its descendants.     */    public static final int FOCUS_BEFORE_DESCENDANTS = 0x20000;    /**     * This view will get focus only if none of its descendants want it.     */    public static final int FOCUS_AFTER_DESCENDANTS = 0x40000;    /**     * This view will block any of its descendants from getting focus, even     * if they are focusable.     */    public static final int FOCUS_BLOCK_DESCENDANTS = 0x60000;

如上说明可知，通过设置FOCUS_BLOCK_DESCENDANTS，可以屏蔽子控件获取焦点。页面将不会弹出输入键盘，从而实现不可编辑。
