Mobile Security Defender Learning (2)

Today is security defender study the next day, mainly involves the following content:

1 Security Defender home Page layout

This involves the use of the GridView, including a reference to the layout file, and a custom control TextView

<?xml version= "1.0" encoding= "Utf-8"?>
<linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"
Android:layout_width= "Match_parent"
android:layout_height= "Match_parent"
android:orientation= "Vertical" >

<textview
android:gravity= "Center"
Android:background= "#8866ff00"
Android:id= "@+id/tv_function_list"
Android:layout_width= "Fill_parent"
android:layout_height= "55dip"
android:text= "Feature List"
Android:textsize= "22SP"
Android:textcolor= "#000000"/>
<com.djf.mobilesafty.ui.focusdtextview
android:layout_margintop= "10dip"
Android:singleline= "true"
Android:ellipsize= "Marquee"
Android:textsize= "22SP"
android:text= "11 days from pre-season, for more information, please login to view details, the new season is more exciting and worth looking forward to"
Android:layout_width= "Fill_parent"
android:layout_height= "Wrap_content"/>
<gridview
Android:verticalspacing= "30dip"
android:layout_margintop= "60dip"
Android:numcolumns= "3"
Android:id= "@+id/gv_item_home"
Android:layout_width= "Match_parent"
android:layout_height= "Match_parent"/>

</LinearLayout>

   return null;
  }

@Override

return 0;
}

}

}

2 Set the layout of the center,

It involves a custom component, where the component involves two TextView, a checkbox, a view, and the action processing of the custom component, which changes the information

Package com.djf.mobilesafty;

Import Com.djf.mobilesafty.ui.SetItemView;

Import android.app.Activity;
Import android.content.SharedPreferences;
Import Android.content.SharedPreferences.Editor;
Import Android.os.Bundle;
Import Android.view.View;
Import Android.view.View.OnClickListener;

public class Setactivity extends Activity {
Private Setitemview Setitemview;
Private Sharedpreferences sp;

  @Override
 protected void OnCreate (Bundle savedinstancestate) {
  //TODO auto-generated method Stub
  super.oncreate (Savedinstancestate);
  setcontentview (R.layout.activity_set);
  sp = getsharedpreferences ("config", mode_private);
  
  setitemview = (setitemview) Findviewbyid (r.id.siv_update);
  boolean update = Sp.getboolean ("Update", false);
  if (update) {
   //automatic upgrade has been turned on
   setitemview.setchecked (true);
   setitemview.setdesc ("open Upgrade");
  }
  else {
   //automatic upgrade has been turned off
   setitemview.setchecked (false);
   setitemview.setdesc ("Off Upgrade");
  }
  setitemview.setonclicklistener (New Onclicklistener () {

@Override
public void OnClick (View v) {
Editor editor = Sp.edit ();
Component has been selected
if (setitemview.ischecked ()) {
Set component unchecked, turn off upgrade
Setitemview.setchecked (FALSE);
Setitemview.setdesc ("Off Upgrade");
Editor.putboolean ("Update", false);
} else//Component not selected
{
Setitemview.setchecked (TRUE);
Setitemview.setdesc ("open Upgrade");
Editor.putboolean ("Update", true);
}
Editor.commit ();
}
});
}
}

customizing component Layouts
