最近感觉这个添加快捷方式挺有趣的,就查资料自己写了个demo---简单的例子,这个例子就是有两个按钮,点击“将此程序添加到快捷方式”,则手机桌面增加一个快捷方式,同时launcher中也多了一个快捷方式,点击退出,则提示:toast弹提示信息“退出程序”。知识梳理:Android平台上添加快捷方式有两种:一种桌面的快捷方式,一种是launcher的快捷方式。原理:是通过intent封装一些信息,以Broadcast的形式通知launcher创建快捷方式的!一定不要忘记在manifest.xml中注册一下权限:

 

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT">

 

在manifest.xml中加入一个动作过滤的intentFilter,快捷方式的列表中会多个该程序的快捷方式。

下面看一下程序的截图:  

 

                             程序的开始界面:                                     点击“将此程序添加快捷方式”按钮:

  \                            \

                                                    

 

         点击退出按钮,桌面多了快捷方式,弹Toast:            点出选择快捷方式后多了程序的快捷方式:

在IntentWidget工程中:

 

一、在com.cn.daming包中IntentWidgetMainActivity.java中的代码:

 

view plaincopy to clipboardprint?

<span><span>  

</span></span><span style="font-size:13px;color:#000000;">package com.cn.daming; 

 

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; 

import android.widget.Toast; 

 

public class IntentWidgetMainActivity extends Activity implements OnClickListener{ 

 

    private Button mStartWidgetButton; 

    private Button mExitButton; 

     

    @Override 

    public void onCreate(Bundle savedInstanceState) { 

        super.onCreate(savedInstanceState); 

        setContentView(R.layout.main); 

        mStartWidgetButton = (Button) findViewById(R.id.my_button_1); 

        mExitButton = (Button) findViewById(R.id.my_button_2); 

        mStartWidgetButton.setOnClickListener(this); 

        mExitButton.setOnClickListener(this); 

    } 

     

    public void onClick(View v) 

    { 

        if(v == mStartWidgetButton){ 

            //inint the widgetIntent is declear  

            Intent addWidgetIntent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT"); 

                     <span style="white-space: pre-wrap;"></span>//whether repeat create is or not   

                     addWdgetIntent.putExtra("duplicate",true);<span style="font-family: monospace;font-size:10px;"><span style="white-space: pre-wrap;"><span><span> 

</span></span></span></span> 

            //set the Widget of the title  

            String mTitle = getResources().getString(R.string.my_title); 

            //set the Widget of the icon  

            Parcelable icon = Intent.ShortcutIconResource.fromContext(this, R.drawable.widget_image); 

             

            Intent mIntent = new Intent(this,IntentWidgetMainActivity.class); 

            addWidgetIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, mTitle);//set the title  

            addWidgetIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);//set the icon  

            addWidgetIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, mIntent);//set the intent  

            sendBroadcast(addWidgetIntent); 

        } 

        else if(v == mExitButton){ 

            finish(); 

            Toast.makeText(IntentWidgetMainActivity.this, R.string.exit, Toast.LENGTH_SHORT).show(); 

        } 

    } 

}</span> 

<span><span>

</span></span><span style="font-size:13px;color:#000000;">package com.cn.daming;

 

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;

import android.widget.Toast;

 

public class IntentWidgetMainActivity extends Activity implements OnClickListener{

 

       private Button mStartWidgetButton;

       private Button mExitButton;

      

       @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        mStartWidgetButton = (Button) findViewById(R.id.my_button_1);

        mExitButton = (Button) findViewById(R.id.my_button_2);

        mStartWidgetButton.setOnClickListener(this);

        mExitButton.setOnClickListener(this);

    }

      

       public void onClick(View v)

       {

              if(v == mStartWidgetButton){

                     //inint the widgetIntent is declear

                     Intent addWidgetIntent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");

                     <span style="white-space: pre-wrap;"></span>//whether repeat create is or not

                     addWdgetIntent.putExtra("duplicate",true);<span style="font-family: monospace;font-size:10px;"><span style="white-space: pre-wrap;"><span><span>

                     //set the Widget of the title

                     String mTitle = getResources().getString(R.string.my_title);

                     //set the Widget of the icon

                     Parcelable icon = Intent.ShortcutIconResource.fromContext(this, R.drawable.widget_image);

                    

                     Intent mIntent = new Intent(this,IntentWidgetMainActivity.class);

                     addWidgetIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, mTitle);//set the title

                     addWidgetIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);//set the icon

                     addWidgetIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, mIntent);//set the intent

                     sendBroadcast(addWidgetIntent);

              }

              else if(v == mExitButton){

                     finish();

                     Toast.makeText(IntentWidgetMainActivity.this, R.string.exit, Toast.LENGTH_SHORT).show();

              }

       }

}</span>

二、在layout目录下的main.xml中的代码:

 

view plaincopy to clipboardprint?

<?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" 

    android:background="#00ffffff" 

    > 

    <TextView    

        android:layout_width="fill_parent"  

        android:layout_height="wrap_content"  

        android:layout_marginTop="15dip" 

        android:layout_marginBottom="15dip" 

        android:gravity="center" 

        android:text="@string/hello" 

        android:textSize="8pt" 

        /> 

    <Button 

        android:id="@+id/my_button_1" 

        android:layout_width="fill_parent" 

        android:layout_height="wrap_content" 

        android:layout_marginBottom="10dip" 

        android:textSize="10pt" 

        android:text="@string/my_button_1" 

    /> 

    <Button 

        android:id="@+id/my_button_2" 

        android:layout_width="fill_parent" 

        android:layout_height="wrap_content" 

        android:layout_marginBottom="10dip" 

        android:textSize="10pt" 

        android:text="@string/my_button_2" 

    /> 

    <TextView   

        android:layout_width="fill_parent"  

        android:layout_height="wrap_content"  

        android:layout_marginBottom="15dip" 

        android:gravity="center" 

        android:text="@string/blogs" 

        android:textSize="8pt" 

        /> 

</LinearLayout> 

<?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"

    android:background="#00ffffff"

    >

       <TextView 

           android:layout_width="fill_parent"

           android:layout_height="wrap_content"

           android:layout_marginTop="15dip"

           android:layout_marginBottom="15dip"

           android:gravity="center"

           android:text="@string/hello"

           android:textSize="8pt"

           />

       <Button

           android:id="@+id/my_button_1"

           android:layout_width="fill_parent"

           android:layout_height="wrap_content"

           android:layout_marginBottom="10dip"

           android:textSize="10pt"

           android:text="@string/my_button_1"

       />

       <Button

           android:id="@+id/my_button_2"

           android:layout_width="fill_parent"

           android:layout_height="wrap_content"

           android:layout_marginBottom="10dip"

           android:textSize="10pt"

           android:text="@string/my_button_2"

       />

       <TextView 

           android:layout_width="fill_parent"

           android:layout_height="wrap_content"

           android:layout_marginBottom="15dip"

           android:gravity="center"

           android:text="@string/blogs"

           android:textSize="8pt"

           />

</LinearLayout>

 

三、在values下的string.xml中的代码:

 

view plaincopy to clipboardprint?

<?xml version="1.0" encoding="utf-8"?> 

<resources> 

    <string name="hello">这是大明添加到Launcher的快捷方式</string> 

    <string name="app_name">大明快捷方式!</string> 

    <string name="my_button_1">将此程序添加快捷方式</string> 

    <string name="my_button_2">退出程序</string> 

    <string name="my_title">大明程序</string> 

    <string name="exit">程序正在退出。。。。。。</string> 

    <string name="blogs">博客地址:\n http://blog.csdn.net/wdaming1986/article/details/6877154</string> 

</resources> 

<?xml version="1.0" encoding="utf-8"?>

<resources>

    <string name="hello">这是大明添加到Launcher的快捷方式</string>

    <string name="app_name">大明快捷方式!</string>

    <string name="my_button_1">将此程序添加快捷方式</string>

    <string name="my_button_2">退出程序</string>

    <string name="my_title">大明程序</string>

    <string name="exit">程序正在退出。。。。。。</string>

    <string name="blogs">博客地址:\n http://blog.csdn.net/wdaming1986/article/details/6877154</string>

</resources>

 

 

 

四、manifest.xml 中的代码

 

view plaincopy to clipboardprint?

<?xml version="1.0" encoding="utf-8"?> 

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 

      package="com.cn.daming" 

      android:versionCode="1" 

      android:versionName="1.0"> 

    <uses-sdk android:minSdkVersion="8" /> 

 

    <application android:icon="@drawable/icon" android:label="@string/app_name"> 

        <activity android:name=".IntentWidgetMainActivity" 

                  android:label="@string/app_name"> 

            <intent-filter> 

                <action android:name="android.intent.action.MAIN" /> 

                <category android:name="android.intent.category.LAUNCHER" /> 

            </intent-filter> 

            <!-- add the launch of my programmer`s quick launcher--> 

            <intent-filter> 

                <action android:name="android.intent.action.CREATE_SHORTCUT"/> 

            </intent-filter> 

        </activity> 

    </application> 

    <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT"/> 

</manifest> 

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

      package="com.cn.daming"

      android:versionCode="1"

      android:versionName="1.0">

    <uses-sdk android:minSdkVersion="8" />

 

    <application android:icon="@drawable/icon" android:label="@string/app_name">

        <activity android:name=".IntentWidgetMainActivity"

                  android:label="@string/app_name">

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

            <!-- add the launch of my programmer`s quick launcher-->

            <intent-filter>

                <action android:name="android.intent.action.CREATE_SHORTCUT"/>

            </intent-filter>

        </activity>

    </application>

    <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT"/>

</manifest>
