android - 识别点击可配置的小部件

Question

我在我的应用程序中托管小部件，需要知道用户何时单击了小部件，或者小部件配置 Intent 何时开始(对于具有配置的小部件)

OnUserLeaveHint 不是一个选项。

我已经完全实现了您想要实现的目标。解决方案的想法是使用 is_clicked=true 的 bundle 参数将 OnClick pending intent 设置到 widget。

这是你可以做的:

1.在使用 RemoteViews 设置小部件布局的同一位置，执行下一步:

/*
 * Create pending intent to configuration activity
 */
Intent intent = new Intent(context, ConfigurationMainActivity.class);

/*
 * Add values with this intent: widget id, and is_clicked = true
 */
Bundle extra = new Bundle();
extra.putInt(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
extra.putBoolean(ConfigurationMainActivity.IS_ON_WIDGET_CLICK_KEY, true);
intent.putExtras(extra);
PendingIntent pendingIntent = PendingIntent.getActivity(context, appWidgetId, intent, PendingIntent.FLAG_UPDATE_CURRENT);

/*
 * Set this intent to one of the views in the widget
 */
remoteViews.setOnClickPendingIntent(R.id.widget_main, pendingIntent);

---

2.当用户单击小部件时，ConfigurationMainActivity Activity 将打开。在此 Activity 中执行下一个编码:

public static final String IS_ON_WIDGET_CLICK_KEY = "IS_ON_WIDGET_CLICK_KEY";

@Override
protected void onCreate(Bundle savedInstanceState)
{
    // some usual stuff
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_configuration);

    Intent intent = getIntent();
    Bundle extras = intent.getExtras();

    // get the widget id that was transferred from on click event
    int appWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);

    // ---> here is what you asking for --->
    // check whereas the widget was clicked by the user or not
    boolean isOnWidgetClick = extras.getBoolean(IS_ON_WIDGET_CLICK_KEY, false);

    if (isOnWidgetClick)
    {
        // ----- Do here whatever you want ------
    }
    else 
    {
        // the code of first time widget configuration 
    }

    ...
    ...
}

注意::

• IS_ON_WIDGET_CLICK_KEY - 只是一个在多个类中使用的常量。您可以在远程 View 设置和此处查看它

希望能帮到你。
