java - Android:如何访问创建的 EditText 中的文本？

Question

如何访问以下代码中创建的 EditText？我可以轻松地从 xml 中创建的 EditText 框中访问文本，但是如何捕获在 for 循环中找到的创建的 EditText 框中输入的内容？:

public class Game extends Activity implements OnClickListener {
   private static final String TAG = "Matrix";
   static int entry1;
   static int entry2;
   static int entry3;
   static int entry4;




@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   this.setContentView(R.layout.matrix);
   View doneButton = findViewById(R.id.done_button);
   doneButton.setOnClickListener(this);

   for(int i = 0; i < MatrixMultiply.h1; i++){
       TableLayout table = (TableLayout)findViewById(R.id.myTableLayout);
       TableRow row = new TableRow(this);
       EditText column = new EditText(this);
       for(int j = 0; j < MatrixMultiply.w1; j++){
           table = (TableLayout)findViewById(R.id.myTableLayout);
           column = new EditText(this);
           column.setId(i);
           row.addView(column);
       }
       table.addView(row);
   }



}

public void onClick(View v) { 
    switch (v.getId()) { 
    case R.id.done_button:
        Intent k = new Intent(this, GameTwo.class);

        final EditText e1 = (EditText) findViewById(R.id.entry1);
        entry1 = Integer.parseInt(e1.getText().toString());

        final EditText e2 = (EditText) findViewById(R.id.entry2);
        entry2 = Integer.parseInt(e2.getText().toString());

        final EditText e3 = (EditText) findViewById(R.id.entry3);
        entry3 = Integer.parseInt(e3.getText().toString());

        final EditText e4 = (EditText) findViewById(R.id.entry4);
        entry4 = Integer.parseInt(e4.getText().toString());

        startActivity(k);
        //finish();
        break;

    }
}

您需要将它们存储在某个地方。

类(class)名列前茅:

EditText[] columnEditTexts;

在 onCreate 中:

columnEditTexts = new EditText[MatrixMultiply.w1];
for(int j = 0; j < MatrixMultiply.w1; j++){
       table = (TableLayout)findViewById(R.id.myTableLayout);
       column = new EditText(this);
       column.setId(i);
       row.addView(column);
       columnEditTexts[j] = column;
   }

阅读它...

for(int j = 0; j < MatrixMultiply.w1; j++){
    String value = columnEditTexts[j].getText().toString();

    // Do whatever you want to do with your value here
}
