将TabHost扩展到linearLayout

问题描述

| 我试图添加一个标签以添加linearLayout。这是我写的代码。

package android.warna;

import android.content.Context;
import android.content.Intent;
import android.content.res.Resources;
import android.util.TypedValue;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
import android.widget.TabHost;
import android.widget.TabWidget;
import android.widget.TextView;


public class XmlTabView extends LinearLayout{

    View view;

    public XmlTabView(Context context) {
        super(context);
        view = new View(context);
         view = createTab(context);
         this.addView(view);

    }

    private android.view.ViewGroup createTab(final Context context) {
        TabHost tabHost = new TabHost(context);
        tabHost.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));

        TabWidget tabWidget = new TabWidget(context);
        tabWidget.setId(android.R.id.tabs);
        tabHost.addView(tabWidget,new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));

        FrameLayout frameLayout = new FrameLayout(context);
        frameLayout.setId(android.R.id.tabcontent);
        frameLayout.setPadding(0,65,0);
        tabHost.addView(frameLayout,LayoutParams.FILL_PARENT));

        tabHost.setup();

        TabHost.TabSpec tabChild1 = tabHost.newTabSpec(\"Child_1\");
        tabChild1.setIndicator(\"Child 1\");

         tabChild1.setContent(new TabHost.TabContentFactory() {
            public View createTabContent(String tag) {
                TextView txt = new TextView(context);
                txt.setText(\"Test Child 1\");
                txt.setTextSize(TypedValue.COMPLEX_UNIT_SP,12f);
                txt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
                return txt;
            }
        });
        tabHost.addTab(tabChild1);

        **Resources res = getResources();
        Intent intent = new Intent().setClass(context,LinearLayOut.class);

        TabHost.TabSpec spec = tabHost.newTabSpec(\"country\").setIndicator(\"country\",res.getDrawable(R.drawable.ic_tab_artists))
                    .setContent(intent);**


        tabHost.addTab(spec);

        TabHost.TabSpec tabChild3 = tabHost.newTabSpec(\"Child_3\");
        tabChild3.setIndicator(\"Child 3\");
        tabChild3.setContent(new TabHost.TabContentFactory() {
            public View createTabContent(String tag) {
                TextView txt = new TextView(context);
                txt.setText(\"Test Child 3\");
                txt.setTextSize(TypedValue.COMPLEX_UNIT_SP,LayoutParams.FILL_PARENT));
                return txt;
            }
        });
        tabHost.addTab(tabChild3);

        return tabHost;
    }
}

它正在工作。但是问题是我无法调用以下活动。

    **Resources res = getResources();
    Intent intent = new Intent().setClass(context,LinearLayOut.class);

    TabHost.TabSpec spec = tabHost.newTabSpec(\"country\").setIndicator(\"country\",res.getDrawable(R.drawable.ic_tab_artists))
                .setContent(intent);**

如果我为该标签页调用了一项活动，则该活动无效。 任何人都可以回答这个问题吗？     

解决方法

        

TabSpec.setContent()

需要

View

，因为您使用的是

Layout

，所以我相信您想要

TabSpec.setContentView()

（以布局作为内容）。
