I used the code below to create a TableRow with content dynamically. It works good but I wish to get the values in the TableRow. Here is the sample code (I got it from Google), it has two text values in the TableRow. When I click the TableRow at any position it gives the corresponding value in the TableRow (I wish something similar to a 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" };

"Mango", "iOS", "Symbian", "Bada", "Android", "Mango", "iOS",
"Symbian", "Bada" };

In the code above some lines are commented, these lines are what I already tried to get the row values but it failed. Can anyone help me with this?
I guess you're talking about getting those values on a TableRow click. If this is the case you could add a listener to your TableRow and use getChildAt to get a hold of the two TextViews and get the data:
//...
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();
}
});
//...
To get data from textview first u need to identify its parent from that u need to get your textView child position then u can get data from it... Here is a sample
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();
}
});
spinnerSelection.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
TableRow selectedRow = (TableRow)spinnerSelection.getParent();
int index = tableLayout.indexOfChild(selectedRow);
Here index is the selected row index value and you can call all the views under the parent row (selectedRow) like the below set of lines.
Button roomNo = (Button) selectedRow.getChildAt(0);
Spinner selectionA = (Spinner) selectedRow.getChildAt(1);
Spinner selectionB = (Spinner) selectedRow.getChildAt(2);
Happy Coding!!

Add clickable textview to table layout dynamically
TextView Delete = new TextView(this);
Delete.setText("Delete");
Delete.setClickable(true);
Delete.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
TransDelete(ac);
}
});
This is my row added dynamically.
public void TransDelete(final String TransID) {
class TransDeleteClass extends AsyncTask<String, Void, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected void onPostExecute(String httpResponseMsg) {
super.onPostExecute(httpResponseMsg);
Toast.makeText(ViewTransactions.this, httpResponseMsg.toString(), Toast.LENGTH_LONG).show();
finish();
}
#Override
protected String doInBackground(String... params) {
// Sending Trans id.
hashMap.put("TransID", params[0]);
finalResult = httpParse.postRequest(hashMap, HttpUrlDeleteRecord);
return finalResult;
}
}
TransDeleteClass TransDeleteClass = new TransDeleteClass();
TransDeleteClass.execute(TransID);
}
This is my onclick function. I tried to click my textview while launching the mulator but the textview does not respond to onclick . I have seen other forums but as I need to pass in my TransID which is not the id i show on screen. For example , I tried filtering the data and although the screen shows numbers added in numeric order, it is not the case for the database i am using.
Edit:
<ScrollView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="none"
android:layout_below="#+id/textView1">
<TableLayout android:layout_width="wrap_content"
android:layout_height="0dp"
android:stretchColumns="1,1,1"
android:id="#+id/maintable" >
</TableLayout>
</ScrollView>
This is my xml page but the table pops up perfectly.
I have chosen to add my headers of the table layout dynamically too.
void addHeader(){
/** Create a TableRow dynamically **/
tr = new TableRow(this);
/** Creating a TextView to add to the row **/
label = new TextView(this);
label.setText("ID");
label.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
label.setPadding(5, 5, 5, 5);
label.setBackgroundColor(Color.RED);
LinearLayout Ll = new LinearLayout(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT);
params.setMargins(5, 5, 5, 5);
Ll.setPadding(10, 5, 5, 5);
Ll.addView(label,params);
tr.addView((View)Ll); // Adding textView to tablerow.
Just a part of my header of the table as adding more codes would require more description.
final TextView[] myTextViews = new TextView[N]; // create an empty array;
for (int i = 0; i < N; i++) {
// create a new textview
final TextView rowTextView = new TextView(this);
// set some properties of rowTextView or something
rowTextView.setText("This is row #" + i);
// add the textview to the tablelayout
yourtable.addView(rowTextView);
// save a reference to the textview for later
myTextViews[i] = rowTextView;
}
I want to add x rows when user press the add button and in one of the row user enters no of types i.e. in edittext then according to that i need to populate that many no.of rows in two columns below that .. these columns alignment is missing..

Currently i'm getting as follows..
I need to adjust those timings and dosage columns accordingly.help me in setting this alignment..
After making below changes in the dynamicEditBox method i got the alignment
public void dynamicEditBox(String id) {

timingsTable.setShrinkAllColumns(true);
for (int i = 0; i < Integer.parseInt(id); i++) {
TableRow tr = new TableRow(MainActivity.this);

parms.setMargins(5, 5, 5, 5);
TextView tv = new TextView(getApplication());
tv.setLayoutParams(parms);
tv.setWidth(50);
tv.setPadding(20, 5, 5, 5);
tv.setId(i);
tv.setHint("10:25am");
tv.setBackgroundColor(Color.LTGRAY);
tr.addView(tv);
EditText et = new EditText(getApplication());
et.setLayoutParams(parms);
et.setPadding(5, 5, 5, 5);
et.setGravity(Gravity.CENTER);
et.setRawInputType(Configuration.KEYBOARD_12KEY);
et.setInputType(InputType.TYPE_CLASS_NUMBER);
et.setId(i);
et.setBackgroundColor(Color.LTGRAY);
et.setHint("dosage");
tr.addView(et);
TableRow.LayoutParams layoutParams = new TableRow.LayoutParams(0,
TableRow.LayoutParams.WRAP_CONTENT, 1f);
layoutParams.setMargins(-15, 10, 0, 0);
timingsTable.setLayoutParams(layoutParams);
timingsTable.addView(tr);
}
}
i got in the below way.
I want to add onClicklistener to the items from the dynamic table that is generated.
My Code is
for(int k=0;k<i;k++)
{
tr[k]=new TableRow(getApplicationContext());
tr[k].layout(0, 0, 0, 0);
ids[k] = new TextView(getApplicationContext());
ids[k].setText(loc_id[k]);
ids[k].setPadding(30, 15, 30, 15);
loc[k] = new TextView(getApplicationContext());
loc[k].setText(loc_name[k]);
loc[k].setPadding(30, 15, 30 ,15);
tr[k].setPadding(0, 1, 0, 0);
tr[k].addView(ids[k]);
tr[k].addView(loc[k]);
tl.addView(tr[k], new TableLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
Please help.
You need to add OnClickListner Interface to your activity and then add all dynamic view to setOnClickListner and finally you can catch click event for all view inside onClick(View view) method.
Try this
public class MainScreen extends Activity implements OnClickListener {
int i = 10; // input no of row
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); // set here your layout xml name
//TableLayout tl = new TableLayout(MainScreen.this);
TableLayout tl = (TableLayout) findViewById(R.id.table);
for (int k = 0; k < i; k++) {
TableRow tr = new TableRow(MainScreen.this);
tr.layout(0, 0, 0, 0);
TextView ids = new TextView(MainScreen.this);
ids.setText(loc_id[k]);
ids.setPadding(30, 15, 30, 15);
TextView loc = new TextView(MainScreen.this);
loc.setText(loc_name[k]);
loc.setPadding(30, 15, 30, 15);
tr.setPadding(0, 1, 0, 0);
tr.addView(ids);
tr.addView(loc);
tr.setId(k); // here you can set unique id to TableRow for
// identification
tr.setOnClickListener(MainScreen.this); // set TableRow onClickListner
tl.addView(tr, new TableLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
//setContentView(tl);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
int clicked_id = v.getId(); // here you get id for clicked TableRow
// now you can get value like this
String ids = loc_id[clicked_id];
String loc = loc_name[clicked_id];
}
}
I have an activity in which I have created a table dynamically. The table is populated from a SQLite database. Onclick the table header the table is getting sorted accordingly.
Everything is working fine, now my requirement is to change the text color of the table header textview when it is clicked. The text color is not getting changed.
This is the a method which is populating the table:
//Time ascending method
public void populateTableTimeAscending()
{
getTimeNameTimeAsc();
getStudentNameTimeAsc();
follow_up_table.removeAllViews();
//---------------Table Header-----------------------------------------------

TextView time_name_title = new TextView(this);
time_name_title.setId(20);
time_name_title.setText("Time");
time_name_title.setTextColor(Color.WHITE);
time_name_title.setPadding(5,5,5,5);
followup_tr_head.addView(time_name_title);// add the column to the table row here
time_name_title.setTextSize(12);
TextView student_name_title = new TextView(this);
student_name_title.setId(20);
student_name_title.setText("Student Name");
student_name_title.setTextColor(Color.WHITE);
student_name_title.setPadding(5,5,5,5);
followup_tr_head.addView(student_name_title);// add the column to the table row here

Inside time_name_title.setOnClickListener(new OnClickListener() I have tried to change the text color which did not happen.

You can also use this:
textview.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
textview.setTextColor(Color.BLUE);
break;
case MotionEvent.ACTION_UP:
textview.setTextColor(Color.BLACk);
break;
}
return false;
}
});
Another way change text color on click is:
Add resource file:
XML file saved at res/color/button_text.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#ffff0000"/> <!-- pressed -->
<item android:state_focused="true"
android:color="#ff0000ff"/> <!-- focused -->
<item android:color="#ff000000"/> <!-- default -->
</selector>
And set as textColor for you widget:
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/button_text"
android:textColor="#color/button_text" />
For more dital look at google guide
Insure that you're trying to change text color in proper TextView and try to call setTextColor after populateTableTimeDescending();
final TextView tv = new TextView(this);
tv.setText("Sample TextView");
rl = (RelativeLayout) findViewById(R.id.rl);
rl.addView(tv);
tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
populateTableTimeDescending();//since you are setting the color of the TextView back to same(white) again in this method, set the color of the textView after calling the method.
tv.setTextColor(Color.parseColor("#FF0000")); //**edited**
}
});
You are trying to set the same color. Check it out.
Please change the color first in any of the method.
--------------edit-------------
then do textview.setColor(Color.BLUE); before populateTableTimeDescending(); in your onClick();
Here, after four digits, you can set whichever color you'd like using a hexadecimal color code:
time_name_title.setTextColor(0xffffffff);
I have list of product.That may be contain 5000 records.I put pagination.First It load 50 records.Then if we press next option(>) then load next 50 option likewise.I designed table-layout.
ArrayList<Product> productList = new ArrayList<Product>();
productList = getProducts();
TableLayout tl;
tl = (TableLayout) findViewById(R.id.tableLayout1);
if(productList.size() >0){
for (int i = 0; i < productList.size(); i++) {
TableRow tr = new TableRow(this);
tr.setTag(i);

int topMargin=2;
int rightMargin=10;

tableRowParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);

TextView txtDes = new TextView(this);

txtQty.setFocusable(true);
txtQty.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
txtQty.setHeight(5);
txtQty.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);
createView(tr, txtCode, productList.get(i).getProductCode());
createView(tr, txtDes, productList.get(i).getDescription());
txtQty.setText(Double.toString(productList.get(i).getPrice()));
tr.addView(txtQty);
createView(tr, txtVal,"Value");
createView(tr, txtDisVal,"0.00");
createView(tr, txtDisQty,"0");
tr.setOnClickListener(new View.OnClickListener(){
public void onClick(View view){
System.out.println("Row Clicked with tag " + view.getTag());
}
});
tl.addView(tr);
}
}
}
public void createView(TableRow tr, TextView t, String viewdata) {
t.setText(viewdata);
t.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
t.setTextColor(Color.DKGRAY);
t.setPadding(1, 0, 0, 0);
tr.setPadding(0, 0, 0, 0);
tr.addView(t);
}
This is my implementation.I didn't implement pagination part yet.
How can I get it into the memory and load it?
Please help me
I suggest you create a function to get products with a param pageindex。
Then you can set a trigger which activated by pagination event。
And update you UI by a handler
