本文实例讲述了Android添加(创建)、删除及判断是否存在桌面快捷方式的方法。分享给大家供大家参考。具体实现方法如下：
public 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 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;
}
public static void delShortcut(Context cx) {
Intent shortcut = new Intent(
"com.android.launcher.action.UNINSTALL_SHORTCUT");
// 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();
Log.v("test", "title:" + title);
} catch (Exception e) {
}
// 快捷方式名称
shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, title);
Intent shortcutIntent = cx.getPackageManager()
.getLaunchIntentForPackage(cx.getPackageName());
shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
cx.sendBroadcast(shortcut);
}
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);
// 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();
Log.v("test", "title:" + title);
} catch (Exception e) {
}
// 快捷方式名称
shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, title);
// 不允许重复创建（不一定有效）
shortcut.putExtra("duplicate", false);
// 快捷方式的图标
Parcelable iconResource = Intent.ShortcutIconResource.fromContext(cx, R.drawable.icon);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);
cx.sendBroadcast(shortcut);
}
希望本文所述对大家的Android程序设计有所帮助。
