Question

我不知道我的代码有什么问题，但每次我把小部件放在主屏幕上按钮1都不起作用。手机重启后，两个按钮都能正常工作......

package cro.perger.bonbon;

import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.widget.RemoteViews;



        public class HelloWidget extends AppWidgetProvider {

                @Override
                public void onUpdate(Context context, AppWidgetManager appWidgetManager,
                        int[] appWidgetIds) {

                            String encodedHash = Uri.encode("#");

                            for (int appWidgetId : appWidgetIds) {

                                Intent callIntent1  = new Intent("android.intent.action.CALL",
                                         Uri.parse("tel:*100" + encodedHash));
                                Intent callIntent2  = new Intent("android.intent.action.CALL",
                                         Uri.parse("tel:*200*1" + encodedHash));

                                PendingIntent pendingIntent1 = PendingIntent.getActivity(context, 0, callIntent1, 0);
                                PendingIntent pendingIntent2 = PendingIntent.getActivity(context, 0, callIntent2, 0);

                                RemoteViews views1 = new RemoteViews(context.getPackageName(), R.layout.widget);
                                views1.setOnClickPendingIntent(R.id.button1, pendingIntent1);

                                RemoteViews views2 = new RemoteViews(context.getPackageName(), R.layout.widget);
                                views2.setOnClickPendingIntent(R.id.button2, pendingIntent2);

                                appWidgetManager.updateAppWidget(appWidgetId, views1);
                                appWidgetManager.updateAppWidget(appWidgetId, views2);
                            }

                }
    }

请帮忙吗？

编辑2：好的，现在它正在运作，但现在又有两个问题。首先，我管理了三个用于发送消息的按钮，但我总是得到相同的消息正文，没有按下我按下的按钮。第二，我需要更改此代码，以便自动发送消息（现在只打开组合消息）....

您所做的是使用两种布局（appWidgetId和views1）更新相同的小部件（views2）。基本上，您在button1（ - ＆gt; views1）上设置了具有待处理意图的小部件布局。然后，您使用仅button2具有待处理意图的布局覆盖它（ - ＆gt; views2）。我不确定为什么这在重新启动后工作，也许安卓通知你使用相同的基本布局资源，并且不会在内部的某处创建它。

那你怎么做的呢？

您可以缩短您的代码段。创建一个布局，在同一布局上设置两个按钮的挂起意图，并像您一样进行更新。但是只有一次，你永远不需要每updateAppWidget()次调用appWidgetId（这与setContentView（）基本上与普通活动相同）。

最终应该是这样的：

Intent callIntent1  = new Intent("android.intent.action.CALL",
                             Uri.parse("tel:*100" + encodedHash));
Intent callIntent2  = new Intent("android.intent.action.CALL",
                     Uri.parse("tel:*200*1" + encodedHash));

PendingIntent pendingIntent1 = PendingIntent.getActivity(context, 0, callIntent1, 0);
PendingIntent pendingIntent2 = PendingIntent.getActivity(context, 0, callIntent2, 0);

RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
views.setOnClickPendingIntent(R.id.button1, pendingIntent1);
views.setOnClickPendingIntent(R.id.button2, pendingIntent2);

appWidgetManager.updateAppWidget(appWidgetId, views);

小部件上的一个按钮不起作用
