Comment puis-je obtenir les valeurs de a créé dynamiquement android TableRow?

J'ai utilisé le code ci-dessous pour créer un TableRow avec du contenu dynamique. Il fonctionne bien, mais je souhaite obtenir les valeurs de la TableRow. Voici un exemple de code (je l'ai eu à partir de Google), il y a deux valeurs de texte dans la TableRow. Quand je clique sur le TableRow à n'importe quelle position il donne la valeur correspondante dans la TableRow (je souhaite quelque chose de semblable à un ListView).

All_CustomsActivity.java

public class All_CustomsActivity extends Activity {
String companies[] = { "Google", "Windows", "iPhone", "Nokia", "Samsung",
"Google", "Windows", "iPhone", "Nokia", "Samsung", "Google",
"Windows", "iPhone", "Nokia", "Samsung" };
String os[] = { "Android", "Mango", "iOS", "Symbian", "Bada", "Android",
"Mango", "iOS", "Symbian", "Bada", "Android", "Mango", "iOS",
"Symbian", "Bada" };
TableLayout tl;
TableRow tr;
TableRow mTable = null;
TextView companyTV, valueTV;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tl = (TableLayout) findViewById(R.id.maintable);
//addHeaders();
addData();
}
/** This function add the headers to the table **/
public void addHeaders() {
/** Create a TableRow dynamically **/
tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
/** Creating a TextView to add to the row **/
TextView companyTV = new TextView(this);
companyTV.setText("Companies");
companyTV.setTextColor(Color.GRAY);
companyTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD);
companyTV.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
companyTV.setPadding(5, 5, 5, 0);
tr.addView(companyTV); //Adding textView to tablerow.
/** Creating another textview **/
TextView valueTV = new TextView(this);
valueTV.setText("Operating Systems");
valueTV.setTextColor(Color.GRAY);
valueTV.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
valueTV.setPadding(5, 5, 5, 0);
valueTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD);
tr.addView(valueTV); //Adding textView to tablerow.
//Add the TableRow to the TableLayout
tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
//we are adding two textviews for the divider because we have two
//columns
tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
/** Creating another textview **/
TextView divider = new TextView(this);
divider.setText("-----------------");
divider.setTextColor(Color.GREEN);
divider.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
divider.setPadding(5, 0, 0, 0);
divider.setTypeface(Typeface.DEFAULT, Typeface.BOLD);
tr.addView(divider); //Adding textView to tablerow.
TextView divider2 = new TextView(this);
divider2.setText("-------------------------");
divider2.setTextColor(Color.GREEN);
divider2.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
divider2.setPadding(5, 0, 0, 0);
divider2.setTypeface(Typeface.DEFAULT, Typeface.BOLD);
tr.addView(divider2); //Adding textView to tablerow.
//Add the TableRow to the TableLayout
tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
/** This function add the data to the table **/
public void addData() {
for (int i = 0; i < companies.length; i++) {
/** Create a TableRow dynamically **/
tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
//ImageView im = new ImageView(this);
//im.setBackgroundResource(R.drawable.sample_image);
//im.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
//LayoutParams.WRAP_CONTENT));
//tr.addView(im);
/** Creating a TextView to add to the row **/
companyTV = new TextView(this);
companyTV.setText(companies[i]);
companyTV.setTextColor(Color.RED);
companyTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD);
companyTV.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
companyTV.setPadding(5, 5, 5, 5);
tr.addView(companyTV); //Adding textView to tablerow.
/** Creating another textview **/
valueTV = new TextView(this);
valueTV.setText(os[i]);
valueTV.setTextColor(Color.GREEN);
valueTV.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
valueTV.setPadding(5, 5, 5, 5);
valueTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD);

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/LinearLayout01"

Dans le code ci-dessus, certaines lignes sont commentées, ces lignes sont ce que j'ai déjà essayé d'obtenir les valeurs de ligne, mais il a échoué. Quelqu'un peut-il m'aider?

Je suppose que vous parlez d'obtenir ces valeurs sur un TableRow cliquez sur. Si c'est le cas, vous pouvez ajouter un écouteur à votre TableRow et l'utilisation getChildAt pour obtenir une prise de les deux TextViews et d'obtenir les données:

//...
tr.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
TableRow t = (TableRow) view;
TextView firstTextView = (TextView) t.getChildAt(0);
TextView secondTextView = (TextView) t.getChildAt(1);
String firstText = firstTextView.getText().toString();
String secondText = secondTextView.getText().toString();
}
});
//...

M'a vraiment aidé, je vous remercie beaucoup!

Pour obtenir des données de textview premier u est nécessaire de déterminer sa mère que u besoin pour obtenir votre textView enfant position, alors u peut obtenir des données à partir de... Voici un exemple de

 String myText;
((TextView) findViewById(R.id.tv)).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {                          
TableRow tablerow = (TableRow)v.getParent();
TextView items = (TextView) tablerow.getChildAt(2);
myText = items.getText().toString();
}
});
