我一直試圖解決這個問題,在android ive的選項卡教程中緊跟着它,但不斷收到我的TabWidget.java類的這個錯誤信息。Android Tab中的錯誤教程
R.drawable.ic_tab_albums不能得到解決
tabWidget.java/HelloTabWidget/src/com/example/tabwidget
和
R.drawable.ic_tab_songs不能得到解決
tabWidget.java/HelloTabWidget/src/com/example/tabwidget
繼承人我爲我的TabWidget.java類
'
進口com.example.androidtab.R代碼;
import android.app.Activity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;
public class TabWidget extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, ArtistsActivity.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_artists))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, AlbumsActivity.class);
spec = tabHost.newTabSpec("albums").setIndicator("Albums",
res.getDrawable(R.drawable.ic_tab_albums))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, SongsActivity.class);
spec = tabHost.newTabSpec("songs").setIndicator("Songs",
res.getDrawable(R.drawable.ic_tab_songs))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(2);
}
private TabHost getTabHost() {
// TODO Auto-generated method stub
return null;
}
}`

特指Ted指出KevinDTimm連接到的答案。它指出,本教程並未指示您創建其他2 xml文件,以使此示例能夠正常工作。 – 2010-12-15 03:04:16
