AlertDialog中的Android TabActivity

Question

How to display TabActivity in AlertDialog? I know that it's a little bit tricky, as we should run TabActivity as normal activity,

eg

Intent intent = new Intent(MyClass.this, Settings.class);
startActivity(intent);

where Settings - TabActvivity.

The only way I know it to set view for AlertDialog, but it will don't work.

View view = (View) ((LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE))
  .inflate(R.layout.settings, null);
new AlertDialog.Builder(this).setTitle("AlertDialog").setView(view).show();

Is there any way to show TabActivity in AlertDialog?

Thanks,

Answer 1

You're sort of conflating the concept of Views and Activities here, but probably the easiest way to do what you want is to set your TabActivity 's theme to Theme.Dialog and start it, instead of using an AlertDialog and trying to wrap an Activity inside a popup inside another Activity . For your own sanity's sake, don't go down that road into Inception-type territory.

I wont really recommend this approach but since you have requested the behavior heres a sample code:

Heres a Tab layout , which has a EditText in tab1 and a Button in tab2

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+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 android:id="@+id/tab1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:layout_centerHorizontal="true"
    >
    <EditText
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="TextBox"
    />

    </LinearLayout>
<Button android:id="@+id/tab2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="A semi-random button"
/>
</FrameLayout></LinearLayout></TabHost>

Code to inflate this layout to a AlertDialog

    AlertDialog.Builder builder=new AlertDialog.Builder(this);
    LayoutInflater inflator=getLayoutInflater();
    View view=inflator.inflate(R.layout.main, null);

    TabHost tabHost=(TabHost)view.findViewById(R.id.tabhost);
    tabHost.setup();
    TabHost.TabSpec spec=tabHost.newTabSpec("tag1");
    spec.setContent(R.id.tab1);
    spec.setIndicator("Clock");
    tabs.addTab(spec);

    spec=tabHost.newTabSpec("tag2");
    spec.setContent(R.id.tab2);
    spec.setIndicator("Button");
    tabs.addTab(spec);

    builder.setView(view);
    builder.setPositiveButton("OK", null);
    builder.create().show();

As I said THIS IS NOT RECOMMENDED APPROACH create a theme instead as suggested by Yoni Samlan above.
