1, about Lancher

To develop a desktop of their own, as programmers, feel that a lot of applications are secretly running traffic.
Develop a desktop program, then resident system service, timed check service.
Monitor other application networks in the system. Integrate some of the common functions.
Make a voice service for flying. Implement some simple human-computer interaction.

2. Modify the configuration file

Add two lines to the Androidmanifest.xml configuration file.

        <activity android:name=". Mainactivity ">            <intent-filter>                <!--Add Lancher configuration --                <category android:name="Android.intent.category.HOME" />                <category android:name="Android.intent.category.DEFAULT" />                <action android:name="Android.intent.action.MAIN" />                <category android:name="Android.intent.category.LAUNCHER" />            </intent-filter>        </activity>

The default activity program then becomes the desktop. By the time you press home.
A selection box will pop up to select the desktop.

3, optimize

Search All Apps

newnull);        mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);        new ImageView(MainActivity.this);        0);        ifnull) {            for (ResolveInfo resolveInfo : apps) {                Log.v(TAG, resolveInfo.toString());            }        }

Displays the returned app to the main interface.
Implement a Baseadapter class. Implement the GetView method.

ResolveInfo info = Apps. Get(i);View Convertview = Layoutinflater. from(mcontent). Inflate(R. Layout. Text_img_view, NULL);ImageView image = (ImageView) convertview. Findviewbyid(R. ID. Image);TextView Text = (TextView) convertview. Findviewbyid(R. ID. Text);Set up text and pictures. Text. SetText(Info. Loadlabel(Getpackagemanager ()));Image. Setimagedrawable(Info. Activityinfo. LoadIcon(Getpackagemanager ()));Convertview. Setscaletype(ImageView. ScaleType. FIT_center);Use DP for parameter setting.            For resolution adaptation. Convertview. Setlayoutparams(New GridView. Layoutparams(int) mresources. Getdimension(R. Dimen. App_width), (int) mresources. Getdimension(R. Dimen. App_height)));Returns a picture-and-text blend. Return Convertview;

Defines a layout

<?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">                <imageview  android:id
      = "@+id/image"  android:layout_width  =< Span class= "Hljs-value" > "50DP"  android:layout_height  =" 50DP " android:layout_gravity  =" Center_horizontal "/>     <TextViewandroid:id= "@+id/text"android:layout_width="Match_ Parent "android:layout_height=" Wrap_content "android:gravity=" center " / >                                </linearlayout>

Above is the picture, below is the text.
Also defines the width and height

<resources>    <dimen name="app_width">90dp</dimen>    <dimen name="app_height">90dp</dimen></resources>

Operating effect:

It's close.
Finally open under Settings. Wallpaper What's. It's all the same.

All code is only 130 lines. But it's interesting.

It's interesting to develop a custom desktop.
I want to control it. A page shows how many apps, text size, icons.
