Android 共享文本/纯文本，以便能够在小部件中使用

问：

我需要在外部应用程序和我的应用程序之间共享文本/纯文本，并将此共享文本用作我需要插入的小部件的 url，请参阅示例图像。

因此，每个小部件都必须具有依赖于此文本的实例。

如何确保在单击共享时，然后在特定应用程序上，小部件会自动插入到主屏幕上。

你能帮我一把吗？

AlarmHandler：

        PendingIntent sender = PendingIntent.getBroadcast(context, 2, intent, FlagPendingIntent);

        AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

        //get current time and add 1 hour
        Calendar c = Calendar.getInstance();
        long l = c.getTimeInMillis() + 10000;//1000*60*60=3600000

唤醒锁：

package com.myapp.test;

import android.content.Context;
import android.os.PowerManager;

public abstract class WakeLocker {

    private static PowerManager.WakeLock wakeLock;

    //wake the device
    public static void acquire(Context context) {
        if (wakeLock != null) {
            wakeLock.release();
        }

        PowerManager powerManager = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK |
                PowerManager.ACQUIRE_CAUSES_WAKEUP |
                PowerManager.ON_AFTER_RELEASE, "WIDGET: Wake lock acquired!");
        wakeLock.acquire(2000);
    }

    public static void release() {
        if (wakeLock != null) {
            wakeLock.release();
        }
        wakeLock = null;
    }

}

import android.widget.RemoteViews;


public class MyWidget extends AppWidgetProvider {

    void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_design);

        Log.d("MyWidget3", values);

        //set the value in the textview
        views.setTextViewText(R.id.text, values);

        //update the widget
        appWidgetManager.updateAppWidget(appWidgetId, views);

        //reschedule the widget refresh
        AlarmHandler alarmHandler = new AlarmHandler(context);
        alarmHandler.cancelAlarmManager();
        alarmHandler.setAlarmManager();

        Log.d("WIDGET", "Widget updated!");
    }

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        for (int appWidgetId: appWidgetIds) {
            updateAppWidget(context, appWidgetManager, appWidgetId);
        }
    }

    @Override
    public void onDisabled(Context context) {
        //stop updating the widget
        AlarmHandler alarmHandler = new AlarmHandler(context);
        alarmHandler.cancelAlarmManager();

        Log.d("WIDGET", "Widget removed!");
    }
}

编辑：

我已经添加了我正在使用的所有类，这些类开始发挥作用，我设法在共享文本时添加小部件。

但是我无法检索小部件端的文本。

你能帮我一把吗？
