Question

탭이있는 앱을로드하는 간단한 프로그램을 만들려고합니다. 그러나 나는 내가 이해하지 못하는 몇 가지 오류가있다. 네가 나를 도울 수 있다면 좋을거야.

미리 감사드립니다.

홈페이지 파일 CustomtabsActivity.java :

package com.example.customtabs; 

import android.app.TabActivity; 
import android.content.Intent; 
import android.content.res.Resources; 
import android.os.Bundle; 
import android.widget.TabHost; 

public class CustomtabsActivity extends TabActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_customtabs); 

     Resources res = getResources(); 
     TabHost tabHost = getTabHost(); 
     TabHost.TabSpec spec; 
     Intent intent; 

     intent = new Intent().setClass(this, Tab1.class); 
     spec = tabHost.newTabSpec("Widget").setIndicator("DateTime", res.getDrawable(android.R.drawable.ic_menu_today)).setContent(intent); 
     tabHost.addTab(spec); 

     intent = new Intent().setClass(this, Tab2.class); 
     spec = tabHost.newTabSpec("Form").setIndicator("Form", res.getDrawable(android.R.drawable.ic_menu_manage)).setContent(intent); 
     tabHost.addTab(spec); 

     intent = new Intent().setClass(this, Tab3.class); 
     spec = tabHost.newTabSpec("onglet3").setIndicator("onglet3", res.getDrawable(android.R.drawable.ic_menu_mapmode)).setContent(intent); 
     tabHost.addTab(spec); 

     tabHost.setCurrentTab(0); 
    } 

} 

Tab1.java : 이상

package com.example.customtabs; 

import android.app.Activity; 
import android.os.Bundle; 



public class Tab1 extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.onglet1); 
    } 
}a 

Tab2.java 및 Tab3.java 거의 동일 Tab1.java.
