我正在android中制作标签。目前这就是我的标签的工作方式。当我单击任何选项卡时，它会将我带到适当的选项卡视图，这很好。但是可以说，当我单击Profile选项卡时，在此profile视图中会有一个按钮Add New。当我单击Add New按钮时，它会将我带到它的视图，但它也会从视图中删除我不想要的选项卡。那么，即使用户单击任何视图内的任何链接或按钮，我如何才能使选项卡始终可用？
这是我当前的代码
选项卡.xml
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp" />
</RelativeLayout>
</TabHost>
标签.java
public class Tabs extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabs);
Resources resources = getResources();
TabHost tabHost = getTabHost();
Intent startUseSaldo = new Intent().setClass(this, Usesaldo.class);
TabSpec useSaldo = tabHost
.newTabSpec("UseSaldo")
.setIndicator("Use Saldo")
.setContent(startUseSaldo);
Intent startHistory = new Intent().setClass(this, History.class);
TabSpec history = tabHost
.newTabSpec("History")
.setIndicator("History")
.setContent(startHistory);
Intent startProfile = new Intent().setClass(this, Profile.class);
TabSpec profile = tabHost
.newTabSpec("Profile")
.setIndicator("Profile")
.setContent(startProfile);
// add all tabs
tabHost.addTab(useSaldo);
tabHost.addTab(history);
tabHost.addTab(profile);
tabHost.setCurrentTab(1);
}
}
配置文件.java
public class Profile extends Activity {
Button bAddNew;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.profile);
bAddNew = (Button)findViewById(R.id.bAddNew);
bAddNew.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent AddFacility = new Intent(getApplicationContext(), AddFacility.class);
startActivity(AddFacility);
}
});
}
}
AddFacility.java
public class AddFacility extends Activity {
@Override
public void setContentView(int layoutResID) {
// TODO Auto-generated method stub
super.setContentView(R.layout.add_facility);
}
}
