我將如何將此代碼轉換爲與Android項目兼容的代碼？

Question

這是我的代碼，它被編譯爲JAVA應用程序。我想要創建的是一個Android應用程序。我只是想問一下，如何將這些代碼轉換爲代碼，以便當我將它編譯爲ANDROID APPLICATION時，它不會產生任何錯誤。

有人可以幫助我如何做到這一點？謝謝

這裏是我的代碼：

public class DouglasMain extends PApplet{ 

public static void main(String args[]) { 
     PApplet.main(new String[] { "--present", "com.RDP.rdp.DouglasMain" }); 
     } 

Vector path = new Vector(); 

public void setup(){ 

    size(550,550); 
    smooth(); 

} 

public void draw(){ 
    background(255); 

    Tuple2f pt; 
    noFill(); 
    strokeWeight(1); 
    beginShape(); 

    for (int i=0; i < path.size(); i++) 

    { 
     pt = (Tuple2f)path.elementAt(i);vertex(pt.x,pt.y); 

    } 

    endShape(); 

    strokeWeight(5); 

    beginShape(POINTS); 

    for (int i=0; i < path.size(); i++) 

    { 
     pt = (Tuple2f)path.elementAt(i);vertex(pt.x,pt.y);  

    } 

    endShape(); 

} 

public void mousePressed(){ 

    path = new Vector(); 

} 

public void mouseDragged(){ 

    path.add(new Tuple2f(mouseX, mouseY)); 

} 

public void mousePressed1(){ 

    //to simplify, get our points into an array of Tuple2f 

    if (path.size() > 1) 

    { 
     Tuple2f [] tmp = new Tuple2f[path.size()-1]; 

     for (int i =0; i < path.size()-1; i++) 

     { 
      tmp[i] = (Tuple2f)path.elementAt(i+1); 

     } 

     path = new Vector(); 
     path.addAll(Arrays.asList(DouglasPeuckerLineSimplifier.simplifyLine2D(5,tmp))); 

    } 

} 
}
