I found the following function that allows you to insert a Widget.

Specifying: createWidget(View view, String packageName, String className)

The problem at the moment is that:

• Some widgets have a configuration phase, such as a WidgetConfigureActivity.
  But it is not called when the widget is inserted into the layout, so some widgets are not inserted correctly.




• Some widgets, take up little space.
  But at the time of insertion take all the space available within the layout.

Any suggestions?

layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/homeScreen"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:background="#000"
 android:orientation="vertical">

 <LinearLayout
 android:id="@+id/viewWidget"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="center_horizontal"
 android:orientation="vertical" />

</LinearLayout>

code:

public boolean createWidget(View view, String packageName, String className) 
 // Get the list of installed widgets
 AppWidgetProviderInfo newAppWidgetProviderInfo = null;
 List<AppWidgetProviderInfo> appWidgetInfos;
 appWidgetInfos = mAppWidgetManager.getInstalledProviders();
 boolean widgetIsFound = false;
 for (int j = 0; j < appWidgetInfos.size(); j++) 
 if (appWidgetInfos.get(j).provider.getPackageName().equals(packageName) && appWidgetInfos.get(j).provider.getClassName().equals(className)) 
 // Get the full info of the required widget
 newAppWidgetProviderInfo = appWidgetInfos.get(j);
 widgetIsFound = true;
 break;
 
 

 if (!widgetIsFound) 
 return false;
 else 
 Log.v("Class", "Ok*");
 // Create Widget
 int appWidgetId = mAppWidgetHost.allocateAppWidgetId();
 AppWidgetHostView hostView = mAppWidgetHost.createView(getApplicationContext(), appWidgetId, newAppWidgetProviderInfo);
 hostView.setAppWidget(appWidgetId, newAppWidgetProviderInfo);

 // Add it to your layout
 LinearLayout widgetLayout = findViewById(R.id.mylockscreen);
 widgetLayout.addView(hostView);

 // And bind widget IDs to make them actually work
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) 
 boolean allowed = mAppWidgetManager.bindAppWidgetIdIfAllowed(appWidgetId, newAppWidgetProviderInfo.provider);

 if (!allowed) 
 // Request permission - https://stackoverflow.com/a/44351320/1816603
 Intent intent = new Intent(AppWidgetManager.ACTION_APPWIDGET_BIND);
 intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
 intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_PROVIDER, newAppWidgetProviderInfo.provider);
 final int REQUEST_BIND_WIDGET = 1987;
 startActivityForResult(intent, REQUEST_BIND_WIDGET);
 
 

 return true;
