在这里，我正在实施一项活动以显示 tabhost.but 我得到错误，因为错误膨胀二进制 xml .... 我在这个论坛上搜索了类似的答案，但没有一个对我有帮助？这是我的活动课
package com.example.iolcalci;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
import android.app.Activity;
public class Menu extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu);
TabHost mTab=(TabHost)findViewById(android.R.id.tabhost);
mTab.setup();
TabSpec specs=mTab.newTabSpec("tag1");
specs.setContent(R.id.srkt_fragment);
specs.setIndicator("SRK/T");
mTab.addTab(specs);
specs=mTab.newTabSpec("tag2");
specs.setContent(R.id.srk2_fragment);
specs.setIndicator("SRK II");
mTab.addTab(specs);
specs=mTab.newTabSpec("tag3");
specs.setContent(R.id.holl_fragment);
specs.setIndicator("HOLLADAY");
mTab.addTab(specs);
specs=mTab.newTabSpec("tag4");
specs.setContent(R.id.bink_fragment);
specs.setIndicator("BINKHORST");
mTab.addTab(specs);
}
}
