Question

我有基于标签的应用程序。在一个选项卡中，我有一个扩展ListActivity的类。在保持标签栏的同时触发onClick时，我需要另一个活动。我希望在保留标签栏的同时将其转移到带有onClick的另一个标签页。

此代码有效但隐藏了标签栏：

Intent intent = new Intent(getApplicationContext(),SectionContentList.class);   

// put values to intent which will get in the LoginSuccess    Activity
Log.d("",appState.MainCategories.get(position).get("feedUrl"));
intent.putExtra("FeedURL", appState.MainCategories.get(position).get("feedUrl"));

// Start LoginSuccess Activity
startActivity(intent);

如何在保留底部标签栏的同时转移到这个新意图？

我已经举例说明了标签活动管理 //已经声明了Activity的使用数量包com.technosoft.Concina_Peru;

import android.app.TabActivity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TabHost;
import android.widget.TextView;

import com.technosoft.FirstTab.FirstTab;
import com.technosoft.FourthTab.FourthTab;
import com.technosoft.SecondTab.SecondTab;
import com.technosoft.ThirdTab.ThirdTab;

public class ConcinaPeruTabbar extends TabActivity {

    public static Context tabContext;
    public static TabHost tabHost;
    Context con;
    public static String var = "";

    public static Concina_Database db;

    private void setupTabHost() {
        tabHost = (TabHost) findViewById(android.R.id.tabhost);
        tabHost.setup();
    }   

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.starttab);
        tabContext = this;
        con = this.getApplicationContext();
        db = new Concina_Database(con);

        setupTabHost();
        setupTab(new TextView(this), "Inicio");
        setupTab(new TextView(this), "Recetas");
        setupTab(new TextView(this), "Favoritos");
        setupTab(new TextView(this), "Mas");

    }



    private void setupTab(final View view, final String tag) {
        View tabview = createTabView(tabHost.getContext(), tag);
        if(tag.equals("Inicio")){

            tabHost.addTab((tabHost.newTabSpec("Inicio")).setIndicator(
                    tabview).setContent(new Intent(this, FirstTab.class)));
        }
        if(tag.equals("Recetas")){

        tabHost.addTab((tabHost.newTabSpec("Recetas")).setIndicator(
                tabview).setContent(new Intent(this, SecondTab.class)));

        }
        if(tag.equals("Favoritos")){

            tabHost.addTab((tabHost.newTabSpec("Favoritos")).setIndicator(
                tabview).setContent(new Intent(this, ThirdTab.class)));

        }
        if(tag.equals("Mas")){

            tabHost.addTab((tabHost.newTabSpec("Mas")).setIndicator(
                tabview).setContent(new Intent(this, FourthTab.class)));

        }
    }

    private static View createTabView(final Context context, final String text) {
        View view = LayoutInflater.from(context)
                .inflate(R.layout.tabs_bg, null);
        TextView tv = (TextView) view.findViewById(R.id.tabsText);

        ImageView iv = (ImageView) view.findViewById(R.id.imageView1);
        if (text.equals("Inicio")) {
            iv.setBackgroundResource(R.drawable.tab_bg_image);
        }
        if (text.equals("Recetas")) {
            iv.setBackgroundResource(R.drawable.tab_bg_image1);
        }
        if (text.equals("Favoritos")) {
            iv.setBackgroundResource(R.drawable.tab_bg_image2);
        }
        if (text.equals("Mas")) {
            iv.setBackgroundResource(R.drawable.tab_bg_image3);
        }

        tv.setText(text);
        return view;
    }
}

//第一个标签活动在此定义

public class FirstTab extends ActivityGroup{
    public static FirstTab group_FirstTab;

    private  ArrayList<View> history = new ArrayList<View>();
    ProgressDialog PD;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        group_FirstTab = this;
        View view = getLocalActivityManager().startActivity("CitiesAct", new
                Intent(FirstTab.this,Inicio.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
        replaceView(view);
    }
    public void replaceView(View view) {  

          history.add(view);
          setContentView(view);

      }
    public void RemoveView(){
         history.clear();

    }
    public void back(){
          if(history.size() > 1) {  
              history.remove(history.size()-1);  
              setContentView(history.get(history.size()-1));

          }else{
              finish();
          }
      }

     public boolean onKeyDown(int keyCode, KeyEvent event)
     {              
            if(keyCode == KeyEvent.KEYCODE_BACK){                   
                group_FirstTab.back();
                    return true;
            }
            return super.onKeyDown(keyCode, event);
     }


}

类似有另一个标签活动.. 现在你想在代码跟随

之后将一个标签转向另一个标签活动到另一个标签活动

对于想要将0标签活动转到1标签活动，然后使用

tab activity Class tab_0{
    ConcinaPeruTabbar.tabHost.setCurrentTab(1); 
}

如果你想将一个标签激活到simaar tab activty，那么使用它查看视图=

  FirstTab.group_FirstTab.getLocalActivityManager().startActivity("CitiesAct", new         Intent(Inicio.this,Platos.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP).putExtra("platos", "Entradas")).getDecorView();
                    FirstTab.group_FirstTab.replaceView(view);

Answer 2

如果您已经实现了一个标签栏，那么您有一个活动 - 我们称之为MyTabActivity - 它扩展了TabActivity。在此活动的OnCreate(Bundle)方法中，您首先在XML中检索TabHost视图来设置标签栏：

TabHost tabHost = (TabHost) findViewById(R.id.tabhost);

要动态处理选项卡选择，可以将TabHost的引用保留为静态变量：

public static final TabHost tabHost;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tabActivityLayout);
    tabHost = (TabHost) findViewById(R.id.tabhost);
    // ..... 
}

然后，您可以从其中一个选项卡活动中访问TabHost，并将当前选项卡设置如下：

MyTabActivity.tabHost.setCurrentTabByTag("the tag you affected to this activity");

OR

MyTabActivity.tabHost.setCurrentTabByTag("the id you may have affected to it");

编辑：在影响TabHost的选项卡时会影响标记，如下所示：

TabHost.TabSpec tabSpec = tabHost.newTabSpec("The Tag").setIndicator(tabView).setContent(intent);
tabHost.addTab(tabSpec);

您应该使用片段在多个活动之间共享部分UI。
