Android标签视图 - 无法创建标签内容，因为找不到包含ID的视图

Question

我正在尝试创建一个标签视图，它将通过Id切换到不同的内容视图。这是我的tab activity：

public class TabViews extends TabActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tabviews);
    TabHost tabHost = getTabHost();

    LayoutInflater.from(this).inflate(R.layout.tabviews, tabHost.getTabContentView(), true);

    tabHost.addTab(tabHost.newTabSpec("apples")
            .setIndicator("Apples")
            .setContent(R.id.apples));
    tabHost.addTab(tabHost.newTabSpec("events")
            .setIndicator("Events")
            .setContent(R.id.events));
    tabHost.addTab(tabHost.newTabSpec("attend")
            .setIndicator("Attending")
            .setContent(R.id.attend));
}
}

这是tabviews xml布局。

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<TextView android:id="@+id/view1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="test"/>   

<TextView android:id="@+id/view2"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="test"/>

<TextView android:id="@+id/view3"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="test"/>

</FrameLayout>

我有三个其他xml布局参加，活动和苹果，我可以通过在startActivity上创建一个新的意图Intent来访问。

这是我的R.java类：

不确定我做错了什么。我对此有点新鲜。

更新：好的..我的意思是..我想使用标签更改活动。继承人就是这样做的。答案是通过Intent设置内容，而不是使用tabHost.addTab（tabHost.newTabSpec（“tab2”）。setIndicator（“Something”）。setContent（new Intent（this，myActivity.class）））;

谢谢所有帮助过的人。这让我考虑了更多的选择。

干杯，乔。

Answer 1

你的xml应该有类似的东西，

  <TabHost
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@android:id/tabhost"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          >

    <FrameLayout  
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView android:id="@+id/view1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="test"/>   

    <TextView android:id="@+id/view2"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="test"/>

    <TextView android:id="@+id/view3"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="test"/>

    </FrameLayout>
    </TabHost>

Answer 2

您的xml布局应该有TabHost和TabWidget，请查看Tab Layout example。

Answer 3

你需要在xml中添加tabwidget .... Checkout，这是如何使用tab小部件：

tabscroll.xml

<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:padding="5dp">
        <HorizontalScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="none">
            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />
        </HorizontalScrollView>
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:padding="5dp" />
    </LinearLayout>
</TabHost>


    public class Tabs5 extends TabActivity implements TabHost.TabContentFactory {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.tabs_scroll);

        final TabHost tabHost = getTabHost();

        for (int i=1; i <= 30; i++) {
            String name = "Tab " + i;
            tabHost.addTab(tabHost.newTabSpec(name)
                    .setIndicator(name)
                    .setContent(this));
        }
    }

    /** {@inheritDoc} */
    public View createTabContent(String tag) {
        final TextView tv = new TextView(this);
        tv.setText("Content for tab with tag " + tag);
        return tv;
    }
}
