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

TableLayout.LayoutParams.WRAP_CONTENT));
TableRow.LayoutParams parms = new TableRow.LayoutParams(0,
TableRow.LayoutParams.WRAP_CONTENT, 1f);
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();

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);

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);
final TableLayout table = (TableLayout) findViewById(R.id.tableLayout);
TableRow row = new TableRow(this);
TextView t2 = new TextView(this);
t2.setText("test");
row.addView(t2);
Button bu = new Button(this);
bu.setBackgroundResource(R.drawable.del);
bu.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
//I need to delete the tablerow
//how to do?
}
});
row.addView(bu);
table.addView(row, new TableLayout.LayoutParams(WC, WC));
**
i want to delete tablerow in bu.setOnClickListener
how to do removeViewAt() ,i cant find indexId
**
use removeView for removing tablerow as:
table.removeView(row);
NOTE: If they don't have unique id then use:
table.removeView(rowIndex);
and by using removeViewAt
for(int i = 0, j < table.getChildCount(); i < j; i++){
// then, you can remove the the row you want...
// for instance...
TableRow row = getChildAt(i);
if( something you want to check ) {
removeViewAt(i);
// or...
removeView(row);
}
}
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);
TableLayout.LayoutParams tableRowParams = new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT);
int leftMargin=10;
int topMargin=2;
int rightMargin=10;
int bottomMargin=2;
tableRowParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);
TextView txtCode = new TextView(this);
TextView txtDes = new TextView(this);
EditText txtQty = new EditText(this);
TextView txtVal = new TextView(this);
TextView txtDisVal = new TextView(this);
TextView txtDisQty = new TextView(this);
txtQty.setId(i);
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
