Question

我想从TabHost：

向活动发送数据或额外内容

public class OngletParcelleListeBatiments extends Activity {

    private TabHost mTabHost;
    private String bien_code;

    public OngletParcelleListeBatiments() {
        super();
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.onglet_parcelle_batiment);

        mTabHost = (TabHost)findViewById(R.id.onglets);

        mTabHost.setup();

        Bundle dataSent = getIntent().getExtras();

        bien_code = dataSent.getString("bien_code");

        // first tab
        TabHost.TabSpec parcelle = mTabHost.newTabSpec("parcelle");
        View onglet = getLayoutInflater().inflate(R.layout.template_tab_onglets, null);
        TextView label = (TextView) onglet.findViewById(R.id.tabLabel);
        label.setText(getResources().getString(R.string.parcelle));
        parcelle.setIndicator(onglet);
        parcelle.setContent(R.id.tabContentParcelle); // I want to send data to the activity of this layout
        mTabHost.addTab(parcelle);

        TabHost.TabSpec batiment = mTabHost.newTabSpec("batiments");
        View onglet = getLayoutInflater().inflate(R.layout.template_tab_onglets, null);
        TextView label = (TextView) onglet.findViewById(R.id.tabLabel);
        label.setText(getResources().getString(R.string.titre_liste_batiments));
        batiment.setIndicator(onglet);
        batiment.setContent(R.id.tabContentBatiments); // I want to send data to the activity of this layout
        mTabHost.addTab(batiment);

        mTabHost.setCurrentTab(0);

    }

}

TabHost onglet_parcelle_batiment.xml的布局：

<?xml version="1.0" encoding="utf-8"?>
<TabHost 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/onglets"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
    >
        <TabWidget
            android:id="@android:id/tabs"
            android:orientation="horizontal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
        />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <include
                android:id="@+id/tabContentParcelle" 
                layout="@layout/parcelle"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />
            <include
                android:id="@+id/tabContentBatiments"
                layout="@layout/liste_batiments"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />
        </FrameLayout>
    </LinearLayout>
</TabHost>

包含的layout id = tabContentParcelle：

我尝试将content的{{1}}设置为TabSpec，但这会导致应用程序崩溃！那么如何将数据或额外内容传递给intent的两个布局/活动content？

如何从TabHost发送数据或额外的布局或活动？
