我创建了一个类，如下

package com.example.tabbedactivity;

import android.app.TabActivity;

import android.content.Intent;

import android.os.Bundle;

import android.view.Menu;

import android.widget.TabHost;

import android.widget.TabHost.TabSpec;

public class TabbedActivity extends TabActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_tabbed);

TabHost tabHost = getTabHost();

// Tab for Photos

TabSpec photospec = tabHost.newTabSpec("Photos");

// setting Title and Icon for the Tab

photospec.setIndicator("Photos", getResources().getDrawable(R.drawable.icon_photos_tab));

Intent photosIntent = new Intent(this, PhotosActivity.class);

photospec.setContent(photosIntent);

// Tab for Songs

TabSpec songspec = tabHost.newTabSpec("Songs");

songspec.setIndicator("Songs", getResources().getDrawable(R.drawable.icon_songs_tab));

Intent songsIntent = new Intent(this, SongsActivity.class);

songspec.setContent(songsIntent);

// Tab for Videos

TabSpec videospec = tabHost.newTabSpec("Videos");

videospec.setIndicator("Videos", getResources().getDrawable(R.drawable.icon_videos_tab));

Intent videosIntent = new Intent(this, VideosActivity.class);

videospec.setContent(videosIntent);

// Adding all TabSpec to TabHost

tabHost.addTab(photospec); // Adding photos tab

tabHost.addTab(songspec); // Adding songs tab

tabHost.addTab(videospec); // Adding videos ta

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.activity_tabbed, menu);

return true;

}

}

，并相应地我已根据可绘制三个XML文件等示于下 icon_photos_tab.xml

android:state_selected="true" />

icon_songs_tab.xml

android:state_selected="true" />

icon_videos_tab.xml

android:state_selected="true" />

现在IDE显示问题，当我尝试访问下绘制这些XML文件编码的精确行如下所示的是TabbedActivity.java(类的一部分，该我已以上示出)

TabSpec songspec = tabHost.newTabSpec("Songs");

songspec.setIndicator("Songs", getResources().getDrawable(R.drawable.icon_songs_tab));

TabSpec photospec = tabHost.newTabSpec("Photos");

// setting Title and Icon for the Tab

photospec.setIndicator("Photos", getResources().getDrawable(R.drawable.icon_photos_tab));

TabSpec videospec = tabHost.newTabSpec("Videos");

videospec.setIndicator("Videos", getResources().getDrawable(R.drawable.icon_videos_tab));

和误差说

个

在该行 多个标志 - icon_photos_tab不能得到解决或无法在现场 - R.drawable不能被解析为一个变量

究竟可能是什么问题(我真的很新的Android。 。这是一种liek我的第一个应用程序，我havenot通过任何理论)

更新 走后，我得到了控制台上以下误差修改
