Question

我创建了一个Android Widget。我有一个问题，就是将活动的结果返回给它的AppWidgetProvider父级。我在网上找了一个答案，确切地写了所有网站上的内容并且它没有用。

我在onReceive方法中设置了一个断点，它甚至没有进入那里。

如果有人可以帮助我，我会很高兴。附件是我的AppWidgetProvider代码和名为ContactsActivity的活动。也附在清单文件中。

的AppWidgetProvider：

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        final int N = appWidgetIds.length;

        for (int i=0; i < N; i++) {
            int appWidgetId = appWidgetIds[i];

            RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);

            Intent informationButtonIntent = new Intent(context, InfoActivity.class);
            informationButtonIntent.setAction(INFO_BUTTON_PRESSED);
            PendingIntent infoPendingIntent = PendingIntent.getActivity(context, 0, informationButtonIntent, 0);

            Intent contactButtonIntent = new Intent(context, ContactsActivity.class);
            contactButtonIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
            contactButtonIntent.setAction(CONTACT_BUTTON_PRESSED);
            PendingIntent contactPendingIntent = PendingIntent.getActivity(context, 0, contactButtonIntent, PendingIntent.FLAG_UPDATE_CURRENT);

            Intent freeNumberButtonIntent = new Intent(context, FreeSMSNumberActivity.class);
            contactButtonIntent.setAction(FREE_NUMBER_BUTTON_PRESSED);
            PendingIntent freeNumberPendingIntent = PendingIntent.getActivity(context, 0, freeNumberButtonIntent, 0);

            remoteViews.setOnClickPendingIntent(R.id.informationButton, infoPendingIntent);
            remoteViews.setOnClickPendingIntent(R.id.contactsButton, contactPendingIntent);
            remoteViews.setOnClickPendingIntent(R.id.freeTextButton, freeNumberPendingIntent);

            appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
        }
    }

    public void onReceive(Context context, Intent intent) {
        // v1.5 fix that doesn't call onDelete Action
        final String action = intent.getAction();
        if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
            final int appWidgetId = intent.getExtras().getInt(
                    AppWidgetManager.EXTRA_APPWIDGET_ID,
                    AppWidgetManager.INVALID_APPWIDGET_ID);
            if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
                this.onDeleted(context, new int[] { appWidgetId });
            }
        }

        else if (intent.getAction().equals("CONTACT_BUTTON_PRESSED")) {

        }


        super.onReceive(context, intent);
    }
}

ContactsActivity：

public class ContactsActivity extends Activity {

    private static final int PICK_CONTACT = 3;

    int mAppWidgetId;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 
        Log.d(UndisclosedSMS.TAG_LOGGER, "Contacts button was pressed");

        Intent parentIntent = getIntent();
        Bundle extras = parentIntent.getExtras();
        if (extras != null) {
            mAppWidgetId = extras.getInt(
                    AppWidgetManager.EXTRA_APPWIDGET_ID, 
                    AppWidgetManager.INVALID_APPWIDGET_ID);
        }

        requestWindowFeature(Window.FEATURE_NO_TITLE);
        Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
        startActivityForResult(intent, PICK_CONTACT);
    }

    @Override
    public void onActivityResult(int reqCode, int resultCode, Intent data){
        super.onActivityResult(reqCode, resultCode, data);

        switch(reqCode){
        case (PICK_CONTACT):
            if (resultCode == Activity.RESULT_OK){
            }
            else {
                Intent resultValue = new Intent();
                resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
                setResult(RESULT_CANCELED, resultValue);
                finish();
            }
            finish();
        }
    }
    finish();
    }
}

的AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.LogiaGroup.UndisclosedSMS"
    android:versionCode="1"

    </application>

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_CONTACTS" />

</manifest>

非常感谢！
