我正在 ListView 下方的脚栏中寻找选项卡类型的按钮，但这没有发生。在这里，我向您展示了两种布局，一种是 Tab Bar，另一种是 ListView。我不确定我应该在哪个布局中添加按钮以将其放在 footbar 下面是我的 ListView 代码和快照:
标签栏.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:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
</TabHost>
列表项选择.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
android:id="@+id/list_item_section_text"
layout="@android:layout/preference_category" />
</LinearLayout>
ListView .xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:minHeight="?android:attr/listPreferredItemHeight"
android:paddingRight="?android:attr/scrollbarSize" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="6dip"
android:layout_marginLeft="0dip"
android:layout_marginRight="6dip"
android:layout_marginTop="6dip"
android:layout_weight="0">
<TextView
android:id="@+id/list_item_entry_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="@+id/list_item_entry_summary"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@id/list_item_entry_title"
android:layout_below="@id/list_item_entry_title"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="?android:attr/textColorSecondary" />
</RelativeLayout>
</LinearLayout>
ListView .java
public class TestListView extends ListActivity {
/** Called when the activity is first created. */
ArrayList<Item> items = new ArrayList<Item>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
items.add(new SectionItem("Category 1"));
items.add(new EntryItem("Item 1", "This is item 1.1"));
items.add(new EntryItem("Item 2", "This is item 1.2"));
items.add(new EntryItem("Item 3", "This is item 1.3"));
items.add(new SectionItem("Category 2"));
items.add(new EntryItem("Item 4", "This is item 2.1"));
items.add(new EntryItem("Item 5", "This is item 2.2"));
items.add(new EntryItem("Item 6", "This is item 2.3"));
items.add(new EntryItem("Item 7", "This is item 2.4"));
items.add(new SectionItem("Category 3"));
items.add(new EntryItem("Item 8", "This is item 3.1"));
items.add(new EntryItem("Item 9", "This is item 3.2"));
items.add(new EntryItem("Item 10", "This is item 3.3"));
items.add(new EntryItem("Item 11", "This is item 3.4"));
items.add(new EntryItem("Item 12", "This is item 3.5"));
EntryAdapter adapter = new EntryAdapter(this, items);
EntryAdapter adapter = new EntryAdapter(this, items);
setListAdapter(adapter);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
if(!items.get(position).isSection()) {
EntryItem item = (EntryItem)items.get(position);
Toast.makeText(this, "You clicked " + item.title , Toast.LENGTH_SHORT).show();
}
super.onListItemClick(l, v, position, id);
}
}
Tabbar.java
public class Support extends TabActivity {
//private ImageView mSpinnerImage = null;
//private Animation mAnimation = null;
private Button button = null;
private TextView synctitle = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*Titlebar + Button*/
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.support);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
button = (Button) findViewById(R.id.syncbutton);
//mSpinnerImage = (ImageView) findViewById(R.id.spinner_view);
//mAnimation = AnimationUtils.loadAnimation(this, R.anim.rotate_animation);
//synctitle = (TextView) findViewById(R.id.synctitle);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//button.setVisibility(View.INVISIBLE);
//mSpinnerImage.setVisibility(View.VISIBLE);
//synctitle.setVisibility(View.VISIBLE);
//mSpinnerImage.setAnimation(mAnimation);
//mSpinnerImage.startAnimation(mAnimation);
}
});
/*Titlebar + Button ends*/
/*Tabs*/
Bundle bundle = getIntent().getExtras();
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
intent = new Intent().setClass(this, TestListView.class);
spec = tabHost .newTabSpec("some_things")
.setIndicator("Info")
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, TestListView.class);
spec = tabHost .newTabSpec("top_things")
.setIndicator("Log")
.setContent(intent);
tabHost.addTab(spec);
//tabHost.getTabWidget().getChildAt(0).getLayoutParams().height = 85;
//tabHost.getTabWidget().getChildAt(1).getLayoutParams().height = 85;
/*Tabs ends*/
}
}
最佳答案
要创建页脚按钮首先创建一个xml文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Button
android:id="@+id/footer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Footer Button" />
</RelativeLayout>
现在在你的 Activity 的 OnCreate 方法中写这个
LayoutInflater inflater = LayoutInflater.from(this);
View v = inflater.inflate(R.layout.button, null);
Button footer = (Button) v.findViewById(R.id.footer);
lv.addFooterView(v); // use getListView() instead of lv if you are using ListActivity
更新
不要使用 ListActivity 而是使用 Activity
首先创建一个xml文件
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<ListView
android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<Button
android:id="@+id/footer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Footer Button"
android:layout_alignParentBottom="true" />
</RelativeLayout>
现在在 onCreate extends Activity 并写在下面几行
setContentView(R.layout.listxml);
在 super.onCreate(bundle) 之后；
