Android應用添加(建立)和刪除及判斷是否存在案頭捷徑-Android新手入門-eoe 移動開發人員論壇 - Powered by Discuz!
Android傳統型程式提供了應用添加和刪除案頭捷徑的功能以及判斷捷徑是否存在,
只要傳入捷徑標題、表徵圖及點擊捷徑執行的應用Intent即可。代碼如下:
1、Android添加案頭捷徑
/**
* 為當前應用添加案頭捷徑
*
* @param cx
* @param appName
* 捷徑名稱
*/
public static void addShortcut(Context cx) {
Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
Intent shortcutIntent = cx.getPackageManager()
.getLaunchIntentForPackage(cx.getPackageName());
shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
// 擷取當前應用程式名稱
String title = null;
try {
final PackageManager pm = cx.getPackageManager();
title = pm.getApplicationLabel(
pm.getApplicationInfo(cx.getPackageName(),
PackageManager.GET_META_DATA)).toString();
} catch (Exception e) {
}
// 捷徑名稱
shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, title);
// 不允許重複建立(不一定有效)
shortcut.putExtra("duplicate", false);
// 捷徑的表徵圖
Parcelable iconResource = Intent.ShortcutIconResource.fromContext(cx,
R.drawable.ic_launcher);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);
cx.sendBroadcast(shortcut);
}
2、Android刪除案頭捷徑
/**
* 刪除當前應用的案頭捷徑
*
* @param cx
*/
public static void delShortcut(Context cx) {
Intent shortcut = new Intent(
"com.android.launcher.action.UNINSTALL_SHORTCUT");
// 擷取當前應用程式名稱
String title = null;
try {
final PackageManager pm = cx.getPackageManager();
title = pm.getApplicationLabel(
pm.getApplicationInfo(cx.getPackageName(),
PackageManager.GET_META_DATA)).toString();
} catch (Exception e) {
}
// 捷徑名稱
shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, title);
Intent shortcutIntent = cx.getPackageManager()
.getLaunchIntentForPackage(cx.getPackageName());
shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
cx.sendBroadcast(shortcut);
}
3、Android判斷應用是否已存在案頭捷徑
/**
* 判斷案頭是否已添加捷徑
*
* @param cx
* @param titleName
* 捷徑名稱
* @return
*/
public static boolean hasShortcut(Context cx) {
boolean result = false;
// 擷取當前應用程式名稱
String title = null;
try {
final PackageManager pm = cx.getPackageManager();
title = pm.getApplicationLabel(
pm.getApplicationInfo(cx.getPackageName(),
PackageManager.GET_META_DATA)).toString();
} catch (Exception e) {
}
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[] { title }, null);
if (c != null && c.getCount() > 0) {
result = true;
}
return result;
}
4、相關許可權配置
<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
