单击主屏幕小部件时如何打开特定片段

Question

单击主屏幕小部件时如何打开特定片段，我已经可以打开 Activity 但我不知道如何从小部件打开片段这是我的小部件 class

public class MyWidget extends AppWidgetProvider {
ComponentName watchWidget;
RemoteViews remoteViews;
private static final String SYNC_CLICKED = "automaticWidgetSyncButtonClick";

void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
                     int appWidgetId) {



    remoteViews = new RemoteViews(context.getPackageName(), R.layout.My_widgets);
    watchWidget = new ComponentName(context, MyWidget.class);
    remoteViews.setTextViewText(R.id.appwidget_text,"Widget Example");
    // start Activity from the widget

    Intent configIntent = new Intent(context, MainActivity.class);
    PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0);
    remoteViews.setOnClickPendingIntent(R.id.widget_container, configPendingIntent);
    appWidgetManager.updateAppWidget(watchWidget, remoteViews);
}

有什么想法吗？

Answer 1

为什么不将一些标志（Bundle）传递给 Intent 并在 Activity onCreate 或 onNewIntent 中检查它，如果设置为 true（或任何值）则打开 Fragment？

小部件：

Intent configIntent = new Intent(context, MainActivity.class);
configIntent.putExtra("key", value);
configIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0);

Activity:

Bundle extras = getIntent().getExtras();
if (extras != null) {
    value_type value = extras.get("key");        
}

请记住，您必须在 onCreate 和 onNewIntent 中都检查它。

对于导航组件使用深层链接

清单：将此行添加到 android 清单

中的 activity 部分

<activity>
    <nav-graph android:value="@navigation/main_nav_graph" />
</activity>

导航图：

<fragment
...>
 <deepLink
            android:id="@+id/deepLink"
            app:uri="myapp://example.com/text" />
</fragment>

ExWidget.kt：在您的小部件文件中声明您的待定意图。

val pendingIntent = NavDeepLinkBuilder(context)
                .setGraph(R.navigation.main_nav_graph)
                .setDestination(R.id.your_fragment)
                .setArguments(
                    YourFragmentArgs.Builder(arguments
                    ).build().toBundle())
                .createPendingIntent()

并在 setOnClickPendingIntent 方法中分配此 pendingIntent，

val views = RemoteViews(context.packageName, R.layout.example_widget)   
views.setOnClickPendingIntent(R.id.example_widget_button, pendingIntent)
