android应用开发之桌面快捷方式

直接code

/**
     * has shortcut
     * 
     * @return
     */
    private boolean hasShortcut() {
        boolean isInstallShortcut = false;
        final ContentResolver cr = this.getContentResolver();
        final String AUTHORITY = "com.android.launcher.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[] { this
                .getString(R.string.app_name).trim() }, null);
        if (c != null && c.getCount() > 0) {
            isInstallShortcut = true;
        }
        return isInstallShortcut;
    }

    /**
     * create shortcut
     */
    private void addShortcut() {
        Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");

        // shortcut name
        shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
        shortcut.putExtra("duplicate", false);

        Intent shortcutIntent = new Intent(Intent.ACTION_MAIN);
        shortcutIntent.setClassName(this, this.getClass().getName());
        shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);

        // this icon of shortcut
        ShortcutIconResource iconRes = Intent.ShortcutIconResource.fromContext(this, R.drawable.ic_launcher);
        shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconRes);

        sendBroadcast(shortcut);
    }

    /**
     * delete shortcut
     */
    private void delShortcut() {
        Intent shortcut = new Intent("com.android.launcher.action.UNINSTALL_SHORTCUT");

        // this name of shortcut
        shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
        String appClass = this.getPackageName() + "." + this.getLocalClassName();
        ComponentName comp = new ComponentName(this.getPackageName(), appClass);
        shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(Intent.ACTION_MAIN).setComponent(comp));

        sendBroadcast(shortcut);

    }

调用处判断下是否有快捷方式，没有创建，即可

        if (!hasShortcut()) {
            addShortcut();
        }
