使用来自支持库的GridLayout会导致NoSuchMethodError：android.support.v4.view.ViewCompat.getLayoutDirection＆＃39;

标签： android android-support-library android-gridlayout

我在我的应用程序中使用GridLayout，它完美无缺。现在我也必须支持android 3.xx，所以我加入了android-support-library-v7。我刚刚在所有地方更改了GridLayout和LayoutParams的import语句。我现在可以构建项目，但是当我运行应用程序时，它会因NoSuchMethodError异常而崩溃。

我遵循了这些steps to include the support library

这是stacktrace：

编辑：代码

public class TableRenderingView extends GridLayout{

    private Context mContext;


    public TableRenderingView(Context context){
        super(context);
        mContext = context; 
        setUseDefaultMargins(true);
        setAlignmentMode(ALIGN_BOUNDS);
        setRowOrderPreserved(false);        
    }
...

}

当我尝试在LinearLayout

中动态添加此扩展类时发生异常 
TableRenderingView trv = new TableRenderingView(context);
                View v = trv.populate(gridRowData);
                LinearLayout ll = ((LinearLayout) tableContainerView.getChildAt(0));
                ll.removeAllViews();
                ll.addView(v);

所以这发生了，因为我的项目所指的android-support-v4库比最新的可用库更旧。由于我们必须手动将android-support-v4.jar库复制到我们的项目/ libs文件夹中，无论你更新sdk多少次，它都会产生一点影响，直到我们手动覆盖支持库.jar那里在项目文件夹中。

我哪里出错了？我的印象是我的项目目录中有最新的android-support-v4.jar。由于我所有尝试通过更改构建路径和顺序来解决此问题都失败了，作为最后的手段我在/ extras / android / support / v4 / android中覆盖了项目/ libs中的android-support-v4.jar - 支持 - v4.jar。瞧它开始工作了。

这就是我将support-v7 gridlayout添加到我的项目中的方式

  1. 复制＆＃39; gridlayout＆＃39;来自＆＃39; \ extras \ android \ support \ v7＆＃39;的文件夹到你的android项目所在的位置
  2. 将步骤1中复制的库作为android-library导入工作区
  3. 在Android应用程序
    4. 上引用step2中导入的库

    注意：

    1. 完成上述步骤后，检查＆＃39; android-support-v7-gridlayour.jar＆＃39;包含在＆＃39; Android依赖关系＆＃39;在你的android应用程序项目下。

    2. 检查为＆＃39; gridlayout＆＃39;添加的新行项目在您的Android应用程序＆＃39; project.properties＆＃39;中。在我的情况下，添加了以下行

       android.library.reference.1=../gridlayout

    3. 除了上述步骤外，我没有按照提及的任何其他步骤进行here

如果您同时使用android-support-v4和android-support-v13，则还需要更新v13。这是我的情况。我已将 v4 更新为最新版本，但仍然出现错误：

  

java.lang.NoSuchMethodError：android.support.v4.view.ViewCompat.hasOnClickListeners 。

我注意到Eclipse在控制台中的消息：“警告：在依赖项列表中找到了android-support-v4和android-support-v13。因为v13包含v4，仅使用v13”。

所以我已将 \ sdk \ extras \ android \ support \ v13 \ android-support-v13.jar 的新版本复制到我项目的libs文件夹中（已替换旧版本） ）错误已经消失。

结论：我们应该立即更新我们项目中使用的所有支持库。

答案 2 :(得分：-1)

我在Xamarin Studio中遇到过类似的问题。我通过以下步骤解决了这个问题：

  1. 清除调试配置中的所有项目。
  2. 清除发布配置中的所有项目。
  3. 手动删除项目中的packages文件夹。 （删除所有Nuget包）。
  4. 重启了 电脑。
  5. 再次运行该项目。
