As you can see, I first create a webview. Then, I want it to immediately disappear. Then, I want the Listview to come up. But the problem is, I can't do Listview if I don't do ListActivity...but then I can't do Activity...
You can most certainly do a ListView
without a ListActivity
. You can also use a WebView
with a ListActivity
.
You can take a look at the code I posted in your other (possibly related) thread: here. I am going to copy same code down: This is my layout XML(weblister.xml):
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:id="@+id/list_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</FrameLayout>
Now, I create an Activity which will have both ListView and WebView in its View heirarchy but only one of them would be Visible:
public class WebAct extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.weblister);
//setup listview
ListView listView = (ListView) findViewById(R.id.list_view);
listView.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
new String[]{"One","Two"}){
});
// setup web view
WebView webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setSupportZoom(false);
webView.loadUrl("http://www.google.com");
// set visibility
listView.setVisibility(View.INVISIBLE);
webView.setVisibility(View.VISIBLE);
}
}
//main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout android:id="@+id/lister"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_alignParentTop="true">
<ListView
android:id="@+id/list_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</RelativeLayout>
<RelativeLayout android:id="@+id/webviewer"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_below="@+id/lister">
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</RelativeLayout>
//java file
package list.View;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class ListViewActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//setup listview
ListView listView = (ListView) findViewById(R.id.list_view);
listView.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
new String[]{"One","Two"}){
});
// setup web view
WebView webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setSupportZoom(false);
//webview.loadUrl("www.google.com");
webView.loadDataWithBaseURL("file:///android_asset/", "<img src=\"banner5.png\" height=\"98%\" width=\"100%\"/>", "text/html", "utf-8", null);
}
}
