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);
    }

}

这是我的xml代码

如果您在布局中使用标签,则使用属性fragment指向片段的类:class

<fragment
     android:id="@+id/bink_fragment"
     class="com.example.iolcalci.Binkhorst_x"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
/>
