使用 android:configChanges=“orientation|keyboardHidden"时的选项卡小部件问题在网格视图中但适用于其他选项卡 [英] Tab Widget Issue when use android:configChanges="orientation|keyboardHidden" in Grid View but working for other Tab

问题描述

我被我的问题困住了.事情是它是一个自定义选项卡小部件.在其中有多个标签像 Home - News - Abc - PQR .

I am stuck with my issue.Thing is that its a custom Tab Widget.In that have multiple tab like Home - News - Abc - PQR .

Activity 应该适用于纵向和横向两种方向.因此，每个选项卡都有 two xml 用于纵向存储在 layout-port/file.xml 和横向存储在 layout-land/file.xml

The Activity should be for both orientation like portrait and landscape. so for that each tab have two xml for portrait which is store at layout-port/file.xml and landscape which store at layout-land/file.xml

为了管理从纵向到横向的方向，我在每个活动中添加了 android:configChanges="orientation|keyboardHidden" 规则标签.

For manage orientation portrait to landscape i have added android:configChanges="orientation|keyboardHidden" rule tag in each activity.

• TAB_SAMPLE.java 选项卡文件.
• TAB_GROUP_ACTIVITY 每个选项卡组活动文件
• file.java 任务文件

• TAB_SAMPLE.java Tab file.
• TAB_GROUP_ACTIVITY each Tab Group activity File
• file.java Task file

毕竟我在这里遇到了问题:

如果我 addandroid:configChanges="orientation|keyboardHidden"rule tag in tab_sample 活动那么它的工作完美.喜欢管理不同的视图.港口到陆地和陆地到港口，但它在 Home.java 中不起作用.

If i addandroid:configChanges="orientation|keyboardHidden"rule tag in tab_sample activity then its working perfect. like manage different view. port to land and land to port but its not working in Home.java.

现在，如果我 删除 tab_sample 活动中的 android:configChanges="orientation|keyboardHidden" 规则标记，那么它适用于 Home 活动而不适用于 News.java

Now if i remove android:configChanges="orientation|keyboardHidden" rule tag in tab_sample activity then its working for Home activity not for News.java

意味着当我改变方向时，它保持相同的 xml 表单端口不从 layout-land 使用.从某种意义上说，它再次调用 OnCreate().

Mean when i change the orientation its keeping same xml form port not use from layout-land.in the sense its call OnCreate() again.

所以我发现可能是选项卡小部件中的问题.

更新

现在跟踪我的代码后，我发现主要问题在于网格视图活动，因为它唯一的活动不起作用.

Now after tracing my code i get that main issue is in grid view activity because its only activity which is not working.

Tab host 与 Grid View 之间存在问题.我不知道为什么它不采用 layout-land xml 文件.我发现 this 为同样的问题，但也没有重播该问题

Issue is between Tab host v/s Grid View. I don't know why its not taking layout-land xml file. i found this as same issue but no replay on that question also

详见manifestfile.xml我想在所有活动中保持纵向和横向.

see in Detail manifestfile.xml I want to maintain both portrait and landscape in all activity.

两个 XML 文件

请帮我解决这个问题.

推荐答案

Oooohhh 最后我得到了上述问题的解决方案.这是非常困难的.

Oooohhh Finally i got the solution for above issue. It's was very difficult.

为了保持横向到纵向的方向状态，反之亦然，我们通常在活动下添加 android:configChanges="keyboardHidden|orientation" 属性标签.

For maintain the state of orientation Landscape to portrait and vice-versa we generally adding android:configChanges="keyboardHidden|orientation" property tag under activity.

但这里 可能是 Tab_Group_Activity 的问题，因为我无法在 GridView 中维护状态.Grid_File.java 是 只有一个 java 文件没有处理好所有其他文件的方向.

But here may be issue is Tab_Group_ Activity due to that i am not able to maintain state in GridView. Grid_File.java is Only single java file which was not handling the orientation rest of all other working perfectly.

现在如果我 从 TAB_SAMPLE.java 中删除 android:configChanges="keyboardHidden|orientation" 那么 它只处理 Grid_File.java 不是其他人.

Now if i remove android:configChanges="keyboardHidden|orientation" from TAB_SAMPLE.java then Its handling only Grid_File.java not others.

mean that was keeping same Layout XML in landscape also where i have two separate XML File.

这是我的解决方案:

我有 add android:configChanges="keyboardHidden|orientation" 在 TAB_SAMPLE.java 以及实现onConfigurationChanged(Configuration newConfig)并设置网格的列数.像 gridView.setNumColumns(6);

I have add android:configChanges="keyboardHidden|orientation" in TAB_SAMPLE.java as well as implement onConfigurationChanged(Configuration newConfig) and set Number of column of grid. like gridView.setNumColumns(6);

@Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        // gridView.setSelection(index);
        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
        {

            // Log.e("On Config Change", "LANDSCAPE");
            gridView.setNumColumns(6);

        } else
        {

            // Log.e("On Config Change", "PORTRAIT");
            gridView.setNumColumns(4);
        }
    }

通常我们在活动下添加 android:configChanges="keyboardHidden|orientation" 标记或 implementing onConfigurationChanged(Configuration newConfig) 但这里我都写了.

Generally we are adding either android:configChanges="keyboardHidden|orientation" tag under activity or implementing onConfigurationChanged(Configuration newConfig) but here i have written both.
