【问题描述】:
自 Android O 起,不推荐使用 com.android.launcher.action.INSTALL_SHORTCUT。在以前的版本中,我使用了它并且它有效。
Intent shortcutintent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
shortcutintent.putExtra("duplicate", false);
shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
Parcelable icon = Intent.ShortcutIconResource.fromContext(getApplicationContext(), R.mipmap.ic_launcher);
shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);
shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(getApplicationContext(), MainActivity.class));
sendBroadcast(shortcutintent);
但现在这不再起作用了。没有创建主屏幕快捷方式。如何在 Android O 中创建主屏幕快捷方式?在源代码中它说@deprecated Replaced with {@link android.content.pm.ShortcutManager#createShortcutResultIntent}。所以我尝试了这个:
ShortcutManager shortcutManager = getSystemService(ShortcutManager.class);
ShortcutInfo.Builder mShortcutInfo = new ShortcutInfo.Builder(MainActivity.this, getString(R.string.app_name));
mShortcutInfo.setShortLabel(getString(R.string.app_name));
mShortcutInfo.setLongLabel(getString(R.string.app_name));
mShortcutInfo.setIcon(Icon.createWithResource(MainActivity.this, R.mipmap.ic_launcher));
shortcutManager.createShortcutResultIntent(mShortcutInfo.build());
我得到了必须提供快捷方式意图的错误:

编辑:
正如 ianhanniballake 的回答中所建议的那样,我设定了意图并得到了java.lang.NullPointerException: intent's action must be set 所以我尝试了new Intent("com.android.launcher.action.INSTALL_SHORTCUT")。代码运行但没有创建快捷方式。
编辑 2: 这是我现在正在运行的代码,但我在主屏幕上看不到快捷方式。
ShortcutManager shortcutManager = getSystemService(ShortcutManager.class);
ShortcutInfo.Builder mShortcutInfo = new ShortcutInfo.Builder(MainActivity.this, getString(R.string.app_name));
mShortcutInfo.setShortLabel(getString(R.string.app_name));
mShortcutInfo.setLongLabel(getString(R.string.app_name));
mShortcutInfo.setIcon(Icon.createWithResource(MainActivity.this, R.mipmap.ic_launcher));
Intent shortcutIntent = new Intent(getApplicationContext(), MainActivity.class);
shortcutIntent.setAction(Intent.ACTION_CREATE_SHORTCUT);
shortcutIntent.putExtra("duplicate", false);
mShortcutInfo.setIntent(shortcutIntent);
sendBroadcast(shortcutManager.createShortcutResultIntent(mShortcutInfo.build()));
编辑 3:
ShortcutInfo.Builder mShortcutInfoBuilder = new ShortcutInfo.Builder(MainActivity.this, getString(R.string.app_name));
mShortcutInfoBuilder.setShortLabel(getString(R.string.app_name));
mShortcutInfoBuilder.setLongLabel(getString(R.string.app_name));
mShortcutInfoBuilder.setIcon(Icon.createWithResource(MainActivity.this, R.mipmap.ic_launcher));
Intent shortcutIntent = new Intent(getApplicationContext(), MainActivity.class);
shortcutIntent.setAction(Intent.ACTION_CREATE_SHORTCUT);
mShortcutInfoBuilder.setIntent(shortcutIntent);
ShortcutInfo mShortcutInfo = mShortcutInfoBuilder.build();
ShortcutManager mShortcutManager = getSystemService(ShortcutManager.class);
mShortcutManager.requestPinShortcut(mShortcutInfo, null);
这会打开权限对话框,如下所示:
但问题是它没有出现在应用程序前台。它仅在按下返回键后出现。它也不会出现在主页键上。
【问题讨论】:
-
你设置权限了吗?
-
是的,
<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" /> -
您是否能够找到在 Android Oreo 及更高版本上不显示对话框的情况下创建快捷方式的解决方案?
