Android ways to create shortcuts through applications _android

The examples in this article describe how Android creates shortcuts through applications. Share to everyone for your reference. Specifically as follows:

Android shortcuts are the most basic components of the desktop. It is used to directly start a component of an application.

In general, you can create a shortcut to the application on the left by long pressing an icon for one application on the list of launcher applications. In addition, you can add shortcuts to your desktop in two ways:

One: Create a intent in the application, and then notify Launcher to create a shortcut in broadcast form.

Two: Register a intentfilter for the application's components, and then add a shortcut to start the component directly on the Launcher desktop.

The following simulation adds a shortcut to the application

Main.xml Layout file:

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android=
"http://schemas.android.com/apk/" Res/android "
 android:orientation=" vertical " 
 android:layout_width=" fill_parent "
 android:layout_" height= "Fill_parent" >
 <button android:id= "@+id/createshortcut" android:layout_width= "Fill_parent"
  android:layout_height= "wrap_content"
  android:layout_gravity= "Center_horizontal"
  android:textsize= "20px"
  android:text= "create shortcut Keys"/>
 <button android:id= @+id/exit "android:layout_width=" Fill_
  Parent "
  android:layout_height=" wrap_content "
  android:layout_gravity=" Center_horizontal "
  Android : textsize= "20px"
  android:text= "Exit"/>
</LinearLayout>

Manifest file:

<?xml version= "1.0" encoding= "Utf-8"?> <manifest xmlns:android=
"http://schemas.android.com/apk/res/" Android "
 package=" Com.ljq.action "android:versioncode=" 1 "
 android:versionname=" 1.0 ">
 < Application android:icon= "@drawable/icon"
  android:label= "@string/app_name" >
  <activity android:name =". Shortcutaction "
   android:label=" @string/app_name ">
   <intent-filter>
    <action android:name= "Android.intent.action.MAIN"/>
    <category
     android:name= "Android.intent.category.LAUNCHER"/>
   </intent-filter>
  </activity>
 </application>
 <uses-sdk android: minsdkversion= "7"/>
 <!--add a shortcut key permission-->
 <uses-permission
  android:name= " Com.android.launcher.permission.INSTALL_SHORTCUT "/>
</manifest>

Shortcutaction class:

Package com.ljq.action;
Import android.app.Activity;
Import android.content.Intent;
Import Android.os.Bundle;
Import android.os.Parcelable;
Import Android.view.View;
Import Android.view.View.OnClickListener;
Import Android.widget.Button; /** * Create shortcuts via application * * @author Jiqinlin */public class Shortcutaction extends activity implements Onclicklistener {Private button Createshortcut=null//Create Shortcut button Private button exit=null;//exit system @Override public void OnCreate (Bundle
  Savedinstancestate) {super.oncreate (savedinstancestate);
  Setcontentview (R.layout.main);
  createshortcut= (Button) Findviewbyid (r.id.createshortcut);
  exit= (Button) Findviewbyid (r.id.exit);
  Createshortcut.setonclicklistener (this);
 Exit.setonclicklistener (this);
  public void OnClick (View v) {//button btn= (Button) v;
   Switch (V.getid ()) {case r.id.createshortcut://string title=getresources (). getString (R.string.title); Intent addintent=new Intent ("Com.android.launcher.action.INSTALL_SHORTCUT"); Parcelable Icon=intent.shortcuticonresource.fromcontext (this, r.drawable.png);
   Gets the icon for the shortcut key Intent myintent=new Intent (this, shortcutaction.class); Addintent.putextra (Intent.extra_shortcut_name, "shortcuts");//Shortcut title Addintent.putextra (intent.extra_shortcut_icon_ RESOURCE, icon);//Shortcut Icons Addintent.putextra (intent.extra_shortcut_intent, myintent);//Shortcut Action Sendbroadcast (
  addintent);/send broadcast break;
   Case R.id.exit:system.exit (0);
  Break

 }
 }
}
