创建桌面快捷方式

本文时在activity中创建桌面快捷方式：

??? public void onCreate(Bundle savedInstanceState) {
??????? super.onCreate(savedInstanceState);
??????? setContentView(R.layout.main);
??????? if(!IfaddShortCut())
??????? ??? createShortCut();
??????? else
??????? ??? Toast.makeText(this, "已经创建", Toast.LENGTH_SHORT).show();
??? }

判断是否已经创建这个应用的快捷方式

?? public? boolean? IfaddShortCut(){

??????? boolean isInstallShortcut = false ;??

????????? final ContentResolver cr = this.getContentResolver();??

????????? //本人的2.2系统是”com.android.launcher2.settings”,网上见其他的为"com.android.launcher.settings"

????????? final String AUTHORITY = "com.android.launcher2.settings";??

????????? final Uri CONTENT_URI = Uri.parse("content://" +??

?????????????????????????? AUTHORITY + "/favorites?notify=true");

????????? Cursor c = cr.query(CONTENT_URI,??

????????? new String[] {"title","iconResource" },??

????????? "title=?",??

????????? new String[] {getString(R.string.app_name ) }, null);//XXX表示应用名称。??

????????????????? if(c!=null && c.getCount()>0){??

????????????? isInstallShortcut = true ;??
????????? }??
????????? return isInstallShortcut ;??
????? }

创建一个桌面快捷方式

??? public void createShortCut(){
??? ??? Intent shortcutintent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
??? ??? //不允许重复创建
??? ??? shortcutintent.putExtra("duplicate", false);
??? ??? //需要现实的名称
??? ??? shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_NAME,getString(R.string.app_name));
??? ??? //快捷图片
??? ??? Parcelable icon = Intent.ShortcutIconResource.fromContext(getApplicationContext(), R.drawable.icon);
??? ??? shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);
??? ??? //点击快捷图片，运行的程序主入口
??? ??? shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(getApplicationContext() , TalbleshutActivity.class));
??? ??? //发送广播。OK
??? ??? sendBroadcast(shortcutintent);
??? }

还要用到两个权限

??? <!-- 创建桌面快捷方式的权限 -->
<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT"/>

<!-- 判断是否已经创建时要用的权限 -->
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS"/>
