Question

我希望NestedScrollView中有CoordinatorLayout，但滚动功能永远不会有效。我不知道我在这里做错了什么。 NestedScrollView内的CoordinatorLayout是否存在问题？有人能告诉我为什么我的布局不可滚动吗？这是我的尝试：

        </LinearLayout>

</android.support.design.widget.CoordinatorLayout>

编辑：添加屏幕截图和布局初始化：

的AndroidManifest.xml：

   <activity android:name=".com.tabs.activity.Comments"
        android:label="View Post"
        android:theme="@style/AppTheme.NoActionBar"
        android:configChanges="keyboardHidden"
        android:windowSoftInputMode="adjustResize|stateVisible|stateAlwaysHidden">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".com.tabs.activity.news_feed"/>
    </activity>

我需要让我的Layout可滚动的原因是由于Comments.java中的这段代码。这在我的数据库中查找并动态地将视图添加到我在comments.xml中描述的containerList布局中。 Comments.java：

public void populateComments(long postId) {
    //Prepare layout inflater and container
    //This is for populating the container container_list
    LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    LinearLayout containerItems = (LinearLayout) findViewById(R.id.container_list); // this replaces your listview
        for (Comment i : commentsDatasource.getCommentsForPost(postId)) {
            View childView = vi.inflate(R.layout.comment_item, null);
            TextView message = (TextView)childView.findViewById(R.id.comment_message);
            TextView name = (TextView) childView.findViewById(R.id.commenter_name);
            TextView timestamp = (TextView) childView.findViewById(R.id.comment_timestamp);
            message.setText(i.getComment());
            name.setText(i.getCommenter());
            timestamp.setText(i.getTimeStamp());
            //Set profile picture
            DraweeController controller = news_feed.getImage(i.getCommenterUserId());
            SimpleDraweeView draweeView = (SimpleDraweeView) childView.findViewById(R.id.commenter_profile_photo);
            draweeView.setController(controller);
            containerItems.addView(childView);
        }
}

正在发生的事情的屏幕截图：您无法看到它，但我的键盘覆盖了名为LinearLayout的{{1}}。

修改：我在container_list

中添加

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

后添加了屏幕截图

您尚未为Toolbar设置任何滚动标记，请尝试将其添加到您的布局中的Toolbar：

app:layout_scrollFlags="scroll|enterAlways"

协调器布局中的嵌套滚动视图不起作用？
