Hello everyone, I am trying to build an android app that will allow the user to create two matrices (A and B) and then perform some operation to get Matrix C IE (A+B=C). The code down below pulls the size of the two arrays from another class. The Class then creates Input boxes for the respective size of the matrix. The problem I am having is referencing the dynamically created matrices so that when the user hits a button Array C can pull values from the created input boxes. If my question is unclear please comment, and I can try to clarify as best as I can. My code is below.
package zach.etier.osu.MC; import android.app.Activity; import android.content.DialogInterface; import android.os.Bundle; import android.view.Gravity; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup.LayoutParams; import android.widget.Button; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.TableLayout; import android.widget.TableRow; public class Matrix extends Activity implements OnClickListener { LinearLayout A,B,C,Container; String gotBread,gotBread2,gotBread3,gotBread4; int Arow,Acol,Brow,Bcol; Button infocalc; TableRow rowA,rowB; String[] myTextViewsA, myTextViewsB; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.home); infocalc=(Button)findViewById(R.id.calc); infocalc.setOnClickListener(this); A=(LinearLayout)findViewById(R.id.arrayA); B=(LinearLayout)findViewById(R.id.arrayB); C=(LinearLayout)findViewById(R.id.arrayC); Container=(LinearLayout)findViewById(R.id.Container); Container.setVisibility(View.INVISIBLE); Bundle gotBasket =getIntent().getExtras(); gotBread=gotBasket.getString("key"); Arow=Integer.parseInt(gotBread); gotBread2=gotBasket.getString("key2"); Acol=Integer.parseInt(gotBread2); gotBread3=gotBasket.getString("key3"); Brow=Integer.parseInt(gotBread3); gotBread4=gotBasket.getString("key4"); Bcol=Integer.parseInt(gotBread4); final EditText[] myTextViewsA = new EditText[Arow]; for (int i = 0; i < Arow; i++) { TableRow rowA = new TableRow(this); rowA.setId(i); for (int j = 0; j < Acol; j++) { EditText cell = new EditText(this); cell.setHint("(" + i + ", " + j + ")"); rowA.addView(cell); myTextViewsA[j] = cell; } A.addView(rowA, new TableLayout.LayoutParams( LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); rowA.setGravity(Gravity.CENTER); } final EditText[] myTextViewsB = new EditText[Brow]; for (int i = 0; i < Brow; i++) { TableRow rowB = new TableRow(this); rowB.setId(i); for (int j = 0; j < Bcol; j++) { EditText cell = new EditText(this); cell.setHint("(" + i + ", " + j + ")"); rowB.addView(cell); myTextViewsB[i] = cell; } B.addView(rowB, new TableLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); rowB.setGravity(Gravity.CENTER); } Container.setVisibility(View.VISIBLE); } public void onClick(View v) { // TODO Auto-generated method stub final EditText[] myTextViewsC = new EditText[Arow]; for (int i = 0; i < Arow; i++) { TableRow rowC = new TableRow(this); for (int j = 0; j < Acol; j++) { EditText cell = new EditText(this); cell.setText("(" + i + ", " + j + ")"); rowC.addView(cell); } C.addView(rowC, new TableLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); rowC.setGravity(Gravity.CENTER); } } }
