根据我给出的代码,我可以添加标签
这是我的主要活动xml activity_main.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" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="5dp" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:fillViewport="true"
android:scrollbars="none" >
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="49dp"
android:layout_marginLeft="0dip"
android:layout_marginRight="0dip" />
</HorizontalScrollView>
<Button
android:id="@+id/add_tab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add" />
</LinearLayout>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="2dp" >
</FrameLayout>
</LinearLayout>
`
tab_event.xml
<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/button_event"
android:clickable="true"
android:focusable="true"
android:text="Default Tab"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
MainActivity.java
package com.example.tabweb2;
import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class MainActivity extends TabActivity {
private static int tabIndex = 0;
private TabHost tabHost;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tabHost = getTabHost();
addTab();
((Button)findViewById(R.id.add_tab)).setOnClickListener(new OnClickListener() {
public void onClick(View v) {
tabIndex++;
addTab();
}
});
}
private void addTab(){
LayoutInflater layoutInflate = LayoutInflater.from(MainActivity.this);
Button tabBtn = (Button)layoutInflate.inflate(R.layout.tab_event, null);
tabBtn.setText("Tab "+tabIndex);
Intent tabIntent = new Intent(MainActivity.this, BlankActivity.class);
setupTab(tabBtn, tabIntent,"Tab "+tabIndex);
}
protected void setupTab(View tabBtn, Intent setClass,String tag) {
TabSpec setContent = tabHost.newTabSpec(tag).setIndicator(tabBtn).setContent(setClass);
tabHost.addTab(setContent);
}}
使用所有标签打开blankactivity
BlankActivity.java
package com.example.tabweb2;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class BlankActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(BlankActivity.this);
tv.setText("Blank activity"+1);
setContentView(tv);
}}
根据我给出的我可以添加新标签(添加按钮)
但我需要这样,这是否可以在每个标签上添加(X)按钮并关闭所选标签?
