Android简单的imageView Widget有两张图片

Question

我试图制作一个由一个imageView组成的小部件，当你点击它时，它会改变为另一个图像，当我在Web按钮上选项卡时，它会打开浏览器并打开一个站点。

我的问题是，关于如何制作小部件没有好的教程，所以我不知道如何做到这一点。

我已经制作了一个小部件布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#09C"
android:padding="@dimen/widget_margin">


<Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentStart="true"
    android:layout_alignParentTop="true"
    android:onClick="Web"
    android:text="Web"
    tools:layout_editor_absoluteX="110dp"
    tools:layout_editor_absoluteY="6dp" />

<Button
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentStart="true"
    android:layout_below="@+id/button"
    android:onClick="onClick"
    android:text="Image" />

<Button
    android:id="@+id/button3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentStart="true"
    android:layout_below="@+id/button2"
    android:onClick="Music"
    android:text="Music" />

<ImageView
    android:id="@+id/imageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentStart="true"
    android:layout_below="@+id/button3"
    android:adjustViewBounds="false"
    android:src="@drawable/fox"
    android:onClick="widgetOnClick"
    android:clickable="true"/>

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentStart="true"
    app:srcCompat="@drawable/fox2"
    />

我已经尝试在我的.java文件中创建一些代码，但是当我注释掉有关imageView的所有内容时，只能打开Web

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


    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setData(Uri.parse("http://www.wykop.pl"));
    PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0);
    RemoteViews views1 = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
    views1.setOnClickPendingIntent(R.id.button, pending);
    appWidgetManager.updateAppWidget(appWidgetId, views1);

    intent = new Intent(Intent.ACTION_VIEW);
    PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, 0);
    RemoteViews views2 = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
    views2.setOnClickPendingIntent(R.id.button2, pendingIntent);
    appWidgetManager.updateAppWidget(appWidgetId, views2);
}




@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    // There may be multiple widgets active, so update all of them
    final int N = appWidgetIds.length;
    for (int i = 0; i < N; i++) {
        updateAppWidget(context, appWidgetManager, appWidgetIds[i]);
    }
}


@Override
public void onEnabled(Context context) {
    // Enter relevant functionality for when the first widget is created
}

@Override
public void onDisabled(Context context) {
    // Enter relevant functionality for when the last widget is disabled
}

public void onReceive(final Context context, Intent intent) {
    super.onReceive(context, intent);

    final AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
    RemoteViews views1 = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
    final RemoteViews views2 = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);


    if (intent.getAction().equals(intent)) {
        appWidgetManager.updateAppWidget(new ComponentName(context, NewAppWidget.class), views1);
    }

    if (intent.getAction().equals(intent)) {
        imageView.setOnClickListener(new View.OnClickListener() {

            public void onClick(View view) {
                imageView2.setVisibility(View.VISIBLE);

                view.setVisibility(View.GONE);
                appWidgetManager.updateAppWidget(new ComponentName(context, NewAppWidget.class), views2);
            }
        });

        imageView2.setOnClickListener(new View.OnClickListener() {

            public void onClick(View view) {
                imageView.setVisibility(View.VISIBLE);

                view.setVisibility(View.GONE);
                appWidgetManager.updateAppWidget(new ComponentName(context, NewAppWidget.class), views2);
            }
        });
     }
   }
}
