不幸的是该程序已停止

Question

我写了一个安卓程序。这有多个选项卡。我希望当我单击一个选项卡（Tab1）时，显示该选项卡的特殊视图（GalleryDemoActivity.java）。但是程序已经停止工作并且不能真正工作！

代码是： src/Tab.java：

package com.AdMd.Plant;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;

public class Tabs extends Activity  {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getActionBar().hide();
        setContentView(R.layout.tabs);
        TabHost tabHost=(TabHost)findViewById(R.id.tabHost);
        tabHost.setup();

        TabSpec spec1=tabHost.newTabSpec("Tab 1");
        Intent photosIntent = new Intent(this, GalleryDemoActivity.class);
        spec1.setContent(photosIntent);
        spec1.setIndicator("اطلاعات گیاه");

        TabSpec spec2=tabHost.newTabSpec("Tab 2");
        spec2.setIndicator("گالری تصاویر");
        spec2.setContent(R.id.tab2);

        TabSpec spec3=tabHost.newTabSpec("Tab 3");
        spec3.setIndicator("گیاهان مشابه");
        spec3.setContent(R.id.tab3);

        tabHost.addTab(spec1);
        tabHost.addTab(spec2);
        tabHost.addTab(spec3);

    }    
}

logcat 消息是：

正如你在logcat中看到的，它告诉我有一个活动组，但是当我使用它时，程序有一些警告，它不再工作了！

警告是：

1.The method onCreate(Bundle) from the type ActivityGroup is deprecated
2.The type ActivityGroup is deprecated

我应该怎么做？ 谢谢..

Answer 1

您必须为每个选项卡提供操作

试试这段代码

public class Tabs extends TabActivity  {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getActionBar().hide();
    setContentView(R.layout.tabs);
    TabHost tabHost=(TabHost)findViewById(R.id.tabHost);


    TabSpec spec1=tabHost.newTabSpec("Tab 1");

    spec1.setIndicator("اطلاعات گیاه");
    spec1.setContent(new Intent(this,GalleryDemoActivity.class));

    TabSpec spec2=tabHost.newTabSpec("Tab 2");
    spec2.setIndicator("گالری تصاویر");
spec2.setContent(new Intent(this,GalleryDemoActivity.class));


    TabSpec spec3=tabHost.newTabSpec("Tab 3");
    spec3.setIndicator("گیاهان مشابه");
    spec3.setContent(new Intent(this,GalleryDemoActivity.class));

    tabHost.addTab(spec1);
    tabHost.addTab(spec2);
    tabHost.addTab(spec3);
}    

}
