创建桌面快捷图标

1、查询快捷图标是否已被创建

private boolean isInstallShortcut() {
        // TODO Auto-generated method stub
        //获取当前使用sdk的版本
        int sdkInt = android.os.Build.VERSION.SDK_INT;
        if(sdkInt >= 8) {
            AUTHORITY = "com.android.launcher2.settings";
        } else {
            AUTHORITY = "com.android.launcher.settings";
        }
        Uri uri = Uri.parse("content://" + AUTHORITY + "/favorites");
        String[] projection = new String[]{"title"};
        String selection = "title = ?";
        String[] selectionArgs = new String[]{"new shortcut"};
        Cursor query = getContentResolver().query(uri, projection, selection, selectionArgs, null);
        
        return query.moveToNext();
    }

2、创建快捷图标

public void installShortcut() {
　　　　　// 查询是否已被创建
        if(isInstallShortcut()) {
             Toast.makeText(this, "该快捷方式已创建", 0).show();
        } else {
            Intent intent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
            //设置快捷方式的名称
            intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "new shortcut");
            //快键方式的图标
            ShortcutIconResource icon = Intent.ShortcutIconResource.fromContext(this, R.drawable.ic_launcher);
            intent.putExtra(Intent.EXTRA_SHORTCUT_ICON, icon);
            Intent myIntent = new Intent();
            //设置一个主入口
            myIntent.setAction("android.intent.action.MAIN");
            myIntent.addCategory("android.intent.category.LAUNCHER");
            //跳转至指定的activity
            ComponentName component = new ComponentName(this, OtherActivity.class);
            myIntent.setComponent(component);
            //跳转意图
            intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, myIntent);
            sendBroadcast(intent);
        }
    }

3、删除快捷图标

public void unInstallShortcut() {
        if(!isInstallShortcut()) {
             Toast.makeText(this, "该快捷方式已被卸载或不存在", 0).show();
        } else {
//            System.out.println("-------------------------unInstall");
            Intent intent = new Intent("com.android.launcher.action.UNINSTALL_SHORTCUT");
            //指定快捷方式的名称
            intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "new shortcut");
            
            Intent myIntent = new Intent();
            //设置一个主入口
            myIntent.setAction("android.intent.action.MAIN");
            myIntent.addCategory("android.intent.category.LAUNCHER");
            //跳转至指定的activity
            ComponentName component = new ComponentName(this, MainActivity.class);
            myIntent.setComponent(component);
            intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, myIntent);
            sendBroadcast(intent);
        }
    }

4、添加使用权限

<!-- 创建Shortcut权限 -->
<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
<!-- 删除Shortcut权限 -->
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT"/>
<!-- 读取设置配置权限 -->
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
