Question

我在应用程序启动时在主屏幕上创建了应用程序的快捷方式，并且它在所有设备上运行良好

但是，在Nexus标签上，它会在每次启动应用时创建多个快捷方式？

如何在App安装时创建一个Shortcut，并在App上卸载它？

private void AddShortcutIconToHomeScreen() {
    Intent shortcutIntent = new Intent(this, EmployeeListActivity.class);
    shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    Intent addIntent = new Intent();
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "Device Tracker");
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
        Intent.ShortcutIconResource.fromContext(getApplicationContext(),
            R.drawable.ic_launcher));
    addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
    addIntent.putExtra("duplicate", false);
    getApplicationContext().sendBroadcast(addIntent);
  }

Answer 1

您可以在调用方法removeShortcut()之前使用方法AddShortcutIconToHomeScreen()删除快捷方式（如果存在）：

方式：

private void removeShortcut() { Intent shortcutIntent = new Intent(this, EmployeeListActivity.class); shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); Intent addIntent = new Intent(); addIntent .putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent); addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "Device Tracker"); addIntent .setAction("com.android.launcher.action.UNINSTALL_SHORTCUT"); getApplicationContext().sendBroadcast(addIntent); }

并在清单文件中添加权限

<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />

使用SharedPreference

解决了我的问题

  private void AddShortcutIconToHomeScreen() {
    boolean mboolean = false;

    SharedPreferences settings = getSharedPreferences("PREFS_NAME", 0);
    mboolean = settings.getBoolean("FIRST_RUN", false);
    if (!mboolean) {
      // do the thing for the first time
      settings = getSharedPreferences("PREFS_NAME", 0);
      SharedPreferences.Editor editor = settings.edit();
      editor.putBoolean("FIRST_RUN", true);
      editor.commit();
      Intent shortcutIntent = new Intent(this, EmployeeListActivity.class);
      shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
      shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

      Intent addIntent = new Intent();
      addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
      addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "Device Tracker");
      addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
          Intent.ShortcutIconResource.fromContext(getApplicationContext(),
              R.drawable.ic_launcher));
      addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
      addIntent.putExtra("duplicate", false);
      getApplicationContext().sendBroadcast(addIntent);
    } else {
      // other time your app loads
    }
  }

添加了AndroidManifest.xml权限。

  <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
    <uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />
