<?xmlversion="1.0"encoding="utf-8"?> <LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="match_parent" android:orientation="horizontal"> <ImageView android:id="@+id/image" android:layout_width="60dp" android:layout_height="60dp" android:padding="10dp"/> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical"> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/text1" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <TextView android:id="@+id/text2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="right"/> </LinearLayout> <TextView android:id="@+id/text3" android:layout_width="fill_parent" android:layout_height="wrap_content"/> </LinearLayout> </LinearLayout> |
二：新建布局文件tab1.xml 存放ListView组件

<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="match_parent"> <ListView android:id="@+id/listview" android:layout_width="fill_parent" android:layout_height="match_parent" tools:context=".MainActivity"/> </RelativeLayout> |
三：新建android activity
Tab1Activity.java

四：编写MainActivity.java 实现选项卡与ListView结合

//继承TabActivity publicclassMainActivity extendsTabActivity { @Override publicvoidonCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 获取选项卡组 TabHost host = getTabHost(); /* * 创建Tab对象 创建意图，tab选项卡与另一个activity连接， * 可以每一个选项对应一个内容，定义一个需要新建一个意图Activity类，设置内容为该意图就可实现 */ Intent intent =newIntent(); intent.setClass(this, Tab1Activity.class); Resources r = getResources(); TabHost.TabSpectab1"tab1") .setIndicator("选项1", r.getDrawable(R.drawable.p5)) .setContent(intent); TabHost.TabSpec tab2 = host.newTabSpec("tab2") .setIndicator("选项2", r.getDrawable(R.drawable.p6)) .setContent(intent); TabHost.TabSpec tab3 = host.newTabSpec("tab3") .setIndicator("选项3", r.getDrawable(R.drawable.p7)) .setContent(intent); // tab与选项卡组绑定 host.addTab(tab1); host.addTab(tab2); host.addTab(tab3); } @Override publicbooleanonCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); returntrue; } } |
