Question

我创建了一个带有1个选项卡的TabHost示例，该选项运行正常。我使用 TabSpec.setContent（TabHost.TabContentFactory contentFactory）

在 TabContentFactory 的标签中添加视图

但是，只要我尝试使用查看/资源ID 使用 TabSpec.setContent（int viewId）在标签中添加标签，我的应用就会崩溃。代码如下：

public class MainAct extends TabActivity implements TabContentFactory{
    protected Resources res;
    protected ListView listView;
    protected LayoutInflater inflater;

    @Override
    public void onCreate(Bundle savedInstanceState) {
    /*init*/
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        res = getResources();
        listView = new ListView(this);

    /*prepare tabs*/
        TabHost tabHost = getTabHost();
        TabSpec spec;

        spec = tabHost.newTabSpec(res.getString(R.string.label_project));
        spec.setIndicator(res.getString(R.string.label_project));
        spec.setContent(this); // << this works perfect
        //spec.setContent(R.id.list_item); // << CRASHES
        //spec.setContent(R.id.list_item2); // << CRASHES
        tabHost.addTab(spec);
    }

    @Override
    public View createTabContent(String tag) {
        return listView;
    }
}

我的XML文件如下

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp"
    android:textSize="22sp"
    android:id="@+id/list_item">
</TextView>

和

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/list_item2"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView android:id="@+id/TextView01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="list_item2">
    </TextView>
</LinearLayout>

它们都正确定义了ID，但它们崩溃了。我已经完成了以下在线教程：

http://android-pro.blogspot.com/2010/08/tabbed-applications-in-android.html

http://www.codeproject.com/KB/android/AndroidTabs.aspx

http://www.androidpeople.com/android-custom-listview-tutorial-example/

所有这些都描述了如何使用ID在标签中添加视图，但没有一个适用于我。

我想要做的就是在布局文件中定义一个视图，并使用ID将其添加到我的选项卡中。请帮忙。

Answer 1

我想要做的就是在布局文件中定义一个视图，并使用ID将其添加到我的选项卡中。

如果你在问题中查看XML文件，你会注意到你没有TabHost，没有TabWidget，没有FrameLayout。我将假设这些是您拒绝在您的问题中包含的第三个XML文件。

按ID添加仅适用于FrameLayout的现有子项，例如this sample project。

您可能想要做的是使用<include>中的FrameLayout元素加载其他文件，或者只是将其内容复制到FrameLayout中并删除单独的文件。

Answer 2

它不会从官方文档中跳出来，但是如果您将视图ID传递给setContent()，则应在setup()之前致电TabHost，然后再致电addTab()。

无法通过ID在TabHost中添加视图，崩溃
