Como obtenho valores de um TableRow android criado dinamicamente?
Eu usei o código abaixo para criar umTableRow
com conteúdo dinamicamente. Funciona bem, mas eu gostaria de obter os valores noTableRow
. Aqui está o código de exemplo (eu peguei do Google), ele tem dois valores de texto noTableRow
. Quando clico noTableRow
em qualquer posição, dá o valor correspondente noTableRow
(Eu desejo algo parecido com umListView
).
All_CustomsActivity.java
<code>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); 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)); // tr.setOnClickListener(new View.OnClickListener() { // public void onClick(View view) { // view.setBackgroundColor(Color.DKGRAY); // } // }); // // tr.setOnLongClickListener(new View.OnLongClickListener() { // public boolean onLongClick(View v) { // mTable = (TableRow) v; // assign selected TableRow gobally // openContextMenu(v); // return true; // } // }); } } // @Override // public void onCreateContextMenu(ContextMenu menu, View v, // ContextMenu.ContextMenuInfo menuInfo) { // super.onCreateContextMenu(menu, v, menuInfo); // menu.add(0, v.getId(), 0, "Do YourStuff"); // // } // // @Override // public boolean onContextItemSelected(MenuItem item) { // int ccount = (mTable).getChildCount(); // String[] str = new String[ccount]; // for (int i = 0; i < ccount; i++) { // TextView tv = (TextView) (((TableRow) mTable)).getChildAt(i); // str[i] = tv.getText().toString(); // set selected text data into the // // String array // } // Toast.makeText(All_CustomsActivity.this, Arrays.toString(str), 2) // .show(); // return true; // } } </code>
main.xml
<code><?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/LinearLayout01" android:layout_width="wrap_content" android:layout_height="wrap_content" > <ScrollView android:layout_width="wrap_content" android:layout_height="wrap_content" android:scrollbars="none" > <TableLayout android:id="@+id/maintable" android:layout_width="fill_parent" android:layout_height="wrap_content" android:stretchColumns="0,1" > </TableLayout> </ScrollView> </LinearLayout> </code>
No código acima algumas linhas são comentadas, essas linhas são o que eu já tentei obter os valores de linha, mas ele falhou. Alguém pode me ajudar com isso?
