Android创建桌面快捷方式

先判断有木有这个快捷方式：

 // 判读是否已经存在快捷方式
    public boolean isExistShortCut() {
        boolean isInstallShortcut = false;
        final ContentResolver cr = Main3Activity.this.getContentResolver();
        // 2.2系统之后是”com.android.launcher2.settings”,之前的为"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);
        if (c != null && c.getCount() > 0) {
            isInstallShortcut = true;
            System.out.println("已经存在快捷方式");
        }
        return isInstallShortcut;
    }

    /**
     * 判断桌面是否已添加快捷方式
     */
    private static boolean hasShortcut(Context cx) {
        boolean result = false;
// 获取当前应用名称
//        String title = null;
//        try {
//            final PackageManager pm = cx.getPackageManager();
//            title = pm.getApplicationLabel(
//                    pm.getApplicationInfo(cx.getPackageName(),
//                            PackageManager.GET_META_DATA)).toString();
//        } catch (Exception ignored) {
//        }
        final String uriStr;
        if (android.os.Build.VERSION.SDK_INT < 8) {
            uriStr = "content://com.android.launcher.settings/favorites?notify=true";
        } else {
            uriStr = "content://com.android.launcher2.settings/favorites?notify=true";
        }
        final Uri CONTENT_URI = Uri.parse(uriStr);
        final Cursor c = cx.getContentResolver().query(CONTENT_URI, null,
                "title=?", new String[]{cx.getString(R.string.app_name)}, null);
        if (c != null && c.getCount() > 0) {
            result = true;
        }
        return result;
    }

　　

AndroidManifast.xml加入权限：

    <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
    <uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT"/>
    <!-- 快捷方式信息需要从setting中读取 -->
    <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS"/>

在onCreate()中加入：

if(!isExistShortCut()){
                    //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.ic_launcher); //获取快捷键的图标
                    Intent myIntent=new Intent(this, MainActivity.class);
                    addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));//快捷方式的标题
                    addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);//快捷方式的图标
                    addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, myIntent);//快捷方式的动作
                    addIntent.putExtra("duplicate",false);
                    sendBroadcast(addIntent);//发送广播
                }
