第一种:继承TabActivity,从TabActivity中用getTabHost()方法获取TabHost。只要定义具体Tab内容布局就行了.
xml布局:
xml布局:
- <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="fill_parent" android:layout_height="fill_parent">
- <LinearLayout android:id="@+id/widget_layout_Blue"
- android:layout_width="fill_parent" android:layout_height="fill_parent"
- android:orientation="vertical" >
- <EditText android:id="@+id/widget34" android:layout_width="fill_parent"
- android:layout_height="wrap_content" android:text="EditText"
- android:textSize="18sp">
- </EditText>
- <Button android:id="@+id/widget30" android:layout_width="wrap_content"
- android:layout_height="wrap_content" android:text="Button">
- </Button>
- </LinearLayout>
- <LinearLayout android:id="@+id/widget_layout_red"
- android:layout_width="fill_parent" android:layout_height="fill_parent"
- android:orientation="vertical" >
- <AnalogClock android:id="@+id/widget36"
- android:layout_width="wrap_content" android:layout_height="wrap_content">
- </AnalogClock>
- </LinearLayout>
- <LinearLayout android:id="@+id/widget_layout_green"
- android:layout_width="fill_parent" android:layout_height="fill_parent"
- android:orientation="vertical">
- <RadioGroup android:id="@+id/widget43"
- android:layout_width="166px" android:layout_height="98px"
- android:orientation="vertical">
- <RadioButton android:id="@+id/widget44"
- android:layout_width="wrap_content" android:layout_height="wrap_content"
- android:text="RadioButton">
- </RadioButton>
- <RadioButton android:id="@+id/widget45"
- android:layout_width="wrap_content" android:layout_height="wrap_content"
- android:text="RadioButton">
- </RadioButton>
- </RadioGroup>
- </LinearLayout>
- </FrameLayout>
- java代码:
- super.onCreate(savedInstanceState);
- myTabhost=this.getTabHost();
- //get Tabhost
- LayoutInflater.from(this).inflate(R.layout.main, myTabhost.getTabContentView(), true);
- myTabhost.setBackgroundColor(Color.argb(150, 22, 70, 150));
- myTabhost
- .addTab(myTabhost.newTabSpec("One")// make a new Tab
- .setIndicator("A")
- // set the Title and Icon
- .setContent(R.id.widget_layout_Blue));
- // set the layout
- myTabhost
- .addTab(myTabhost.newTabSpec("Two")// make a new Tab
- .setIndicator("B",
- getResources().getDrawable(R.drawable.mumule))
- // set the Title and Icon
- .setContent(R.id.widget_layout_green));
- // set the layout
- myTabhost
- .addTab(myTabhost.newTabSpec("Three")// make a new Tab
- .setIndicator("C",
- getResources().getDrawable(R.drawable.notepad))
- // set the Title and Icon
- .setContent(R.id.widget_layout_red));
第二种:不用继承TabActivity,在布局文件中定义TabHost即可,但是TabWidget的id必须是
@android:id/tabs,FrameLayout的id必须是@android:id/tabcontent。TabHost的id可以自定义.
xml布局:
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:id="@+id/hometabs"
- android:orientation="vertical"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent">
- <TabHost android:id="@+id/tabhost"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content">
- <LinearLayout
- android:orientation="vertical"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent">
- <TabWidget android:id="@android:id/tabs"
- android:orientation="horizontal"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content">
- </TabWidget>
- <FrameLayout android:id="@android:id/tabcontent"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content">
- <TextView android:id="@+id/view1"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"/>
- <TextView android:id="@+id/view2"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"/>
- <TextView android:id="@+id/view3"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"/>
- </FrameLayout>
- </LinearLayout>
- </TabHost>
- </LinearLayout>
- java代码:
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.hometabs);
- TabHost tabHost = (TabHost) findViewById(R.id.tabhost);
- tabHost.setup();
- TabWidget tabWidget = tabHost.getTabWidget();
- tabHost.addTab(tabHost.newTabSpec("tab1")
- .setIndicator("tab1", getResources().getDrawable(R.drawable.mumule))
- .setContent(R.id.view1));
- tabHost.addTab(tabHost.newTabSpec("tab3")
- .setIndicator("tab3")
- .setContent(R.id.view3));
- tabHost.addTab(tabHost.newTabSpec("tab2")
- .setIndicator("tab2")
- .setContent(R.id.view2));
- final int tabs = tabWidget.getChildCount();
- Log.i(TAG, "***tabWidget.getChildCount() : " + tabs);
- final int tabWidth = 90;
- final int tabHeight = 45;
- for (int i = 0; i < tabs; i++) {
- /* final View view = tabWidget.getChildAt(i);
- view.getLayoutParams().width = tabWidth;
- view.getLayoutParams().height = tabHeight;
- final TextView tv = (TextView) view.findViewById(android.R.id.title);
- tv.setTextColor(this.getResources().getColorStateList(android.R.color.black));
- MarginLayoutParams tvMLP = (MarginLayoutParams)tv.getLayoutParams();
- tvMLP.bottomMargin = 8;*/
- }
- }
