Processing to Android visualization on Android

  I have tried the following to load two Processing sketches underneath each other..

  Layout file: two FrameLayouts, each for one Processing Sketch..

  <?xml version="1.0" encoding="utf-8"?>
  <android.support.constraint.ConstraintLayout 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"
      tools:context="com.example.gebruiker.myapplication.MainActivity">
  
      <FrameLayout
          android:id="@+id/FrameLayoutWeather"
          android:layout_width="327dp"
          android:layout_height="226dp"
          android:layout_marginBottom="16dp"
          android:layout_marginEnd="8dp"
          android:layout_marginStart="8dp"
          app:layout_constraintBottom_toBottomOf="parent"
          app:layout_constraintEnd_toEndOf="parent"
          app:layout_constraintHorizontal_bias="0.512"
          app:layout_constraintStart_toStartOf="parent">
  
      </FrameLayout>
  
      <FrameLayout
          android:id="@+id/FrameLayoutSketch"
          android:layout_width="327dp"
          android:layout_height="214dp"
          android:layout_marginEnd="8dp"
          android:layout_marginStart="8dp"
          android:layout_marginTop="16dp"
          app:layout_constraintEnd_toEndOf="parent"
          app:layout_constraintStart_toStartOf="parent"
          app:layout_constraintTop_toTopOf="parent">
  
      </FrameLayout>
  
  </android.support.constraint.ConstraintLayout>
  

  And the MainActivity..

  public class MainActivity extends AppCompatActivity {
  
      private PApplet sketch;
      private PApplet secondsketch;
      FrameLayout frameLayout_weather;
      FrameLayout frameLayout_sketch;
  
      @ Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
  
          frameLayout_sketch = findViewById(R.id.FrameLayoutSketch);
          frameLayout_weather = findViewById(R.id.FrameLayoutWeather);
  
          sketch = new weatherBrussels();
          PFragment fragment_sketch = new PFragment(sketch);
          fragment_sketch.setView(frameLayout_sketch, this);
  
          secondsketch = new second_sketch();
          PFragment fragment_weather = new PFragment(secondsketch);
          fragment_weather.setView(frameLayout_weather, this);
  
      }
  
      @ Override
      public void onRequestPermissionsResult(int requestCode,
                                             String permissions[],
                                             int[] grantResults) {
          if (sketch != null) {
              sketch.onRequestPermissionsResult(requestCode, permissions, grantResults);
          }
          if (secondsketch != null) {
              secondsketch.onRequestPermissionsResult(requestCode, permissions,grantResults);
          }
      }
  
      @ Override
      public void onNewIntent(Intent intent) {
          if (sketch != null) {
              sketch.onNewIntent(intent);
          }
          if (secondsketch!= null){
              secondsketch.onNewIntent(intent);
          }
      }
  }
  

  I do not get an error message, but the Android Studio Project does not work either.

  Any ideas?

  • a lot of problems there...first one is that you never add any fragment as it must be done, with a FragmentManager instance: so nothing can be seen!

  So I can just treat PFragments as Fragments then, ok.. Since I want my sketches to be loaded when the page is loaded, just in different views, can I also use other View types, like CardView or ListView? Or with Processing sketches, am I obliged to use the PFragment (Fragment) approach?

  Thanks for your help!

  with P5 you are in a fragment; but you can add all kind of android views to this fragment: i have put in the forum many examples for that: textView, videoView; not tried with listView but it s probably the same. As for adding (not replacing) another fragments i dont think that it is possible, except perhaps using nested fragments: the first one is created by the main activity and it contains your first sketch; when it is created it creates a second fragment with another sketch using a fragment transaction with getChildFragmentManager(): i have not tested that but logically it could work...I ' ll have a look.

  sounds great, where can I find these examples? I have checked your profile, but since you have over 1,5K posts it is a bit hard to find them.. :-)

  I have found an answer to my questions.. Answer lie in setting a Static ID to my FrameLayouts and then losing the "SetContentView()" method..

  package com.example.gebruiker.myapplication;
  
  import android.content.Intent;
  import android.os.Bundle;
  import android.support.v7.app.AppCompatActivity;
  import android.widget.FrameLayout;
  import processing.android.PFragment;
  import processing.core.PApplet;
  
  public class MainActivity extends AppCompatActivity {
  
      private PApplet sketch1;
      private PApplet sketch2;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          FrameLayout frame1 = new FrameLayout(this);
          frame1.setId(R.id.FrameLayoutTwo);
  
          FrameLayout frame2 = new FrameLayout(this);
          frame2.setId(R.id.FrameLayoutOne);
  
          sketch1 = new sketchone();
          PFragment fragment1 = new PFragment(sketch1);
          fragment1.setView(frame1, this);
  
          sketch2 = new second_sketch();
          PFragment fragment2 = new PFragment(sketch2);
          fragment2.setView(frame2, this);
      }
  
      @Override
      public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
          if (sketch1 != null) {
              sketch1.onRequestPermissionsResult(
                      requestCode, permissions, grantResults);
          }
  
          if (sketch2 != null) {
              sketch2.onRequestPermissionsResult(
                      requestCode, permissions, grantResults);
          }
  
      }
  
      @Override
      public void onNewIntent(Intent intent) {
          if (sketch1 != null) {
              sketch1.onNewIntent(intent);
          }
  
          if (sketch2 != null) {
              sketch2.onNewIntent(intent);
          }
      }
