这里有一些问题
我会尝试向androidhive.com学习,然后我会看到这个教程,但是当我在eclipse中编写它时,它失败了。
package com.uavero.androidtablayout;
import android.os.Bundle;
import android.app.TabActivity;
import android.content.Intent;
import android.view.Menu;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class TabLayout extends TabActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab_layout);
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_photo_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_song_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_video_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 tab
}
@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_tab_layout, menu);
return true;
}
}
答案 0 :(得分:0)
我可以解决这个问题。 Android 3.0和高级版不支持TabActivity, 或者如果您正在使用较低版本但仍然发生错误,则更改此行代码; - TabHost tabHost = getTabHost();, import.app.TabActivity,和 TabHost tabHost =(TabHost)findViewById(R.id.tabhost)。
