I have this LinearLayout and inside it, there is a button and a TableLayout with no rows till now, i'll add them dynamically.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/btn_select" />
<TableLayout
android:id="#+id/tablay"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TableLayout>
On click of the button I want the camera to be open and the image clicked to be set on an ImageView inside a new tablerow.
Now here is the java snippet.
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button1);
tableLayout = (TableLayout) findViewById(R.id.tablay);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
bitmap = (Bitmap) data.getExtras().get("data");
tableRow = new TableRow(this);
tableRow.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
imageView = new ImageView(this);
imageView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
imageView.setImageBitmap(bitmap);
tableRow.addView(imageView);
tableLayout.addView(tableRow);
}
Everything goes fine but the image doesn't show up on the screen.
Edit:
tableRow = new TableRow(this);
imageView = new ImageView(this);
tableRow.addView(imageView,new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
Set Params like this, because table row accept params of type TableRow only
tableRow.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
In the main.xml file,
<TableRow
android:id="#+id/infoRow"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:text="Loading Content"
android:id="#+id/loadingMessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<Button
android:id="#+id/insert"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="Add New" />
</TableRow>
for eg: say testItem.java
public class testItem extends Activity
{
private List<String> results = new ArrayList<String>(); // Please add values to this string list.
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle bundle)
{
super.onCreate(bundle);
setContentView(R.layout.main);
int count=results.size();
TableLayout tl=(TableLayout)findViewById(R.id.mainLayout);
for(int i=0;i<count;i++)
{
final String str=results.get(i);
TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
TextView textview = new TextView(this);
textview.setText(str);
tr.addView(textview);
Button buttn = new Button(this);
buttn.setText("DELETE");
buttn.setTextColor(Color.BLUE);
tr.addView(buttn);
tl.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
}
}
Remove imageView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
Change tableRow.addView(imageView);
to
tableRow.addView(imageView,100,150); (new width and height)

I want to add a TextView dynamically to the SlidingDrawer. Below is my XML code:
<SlidingDrawer
android:id="#+id/sdDrawerBottom"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true"
android:content="#+id/sdBottomContent"
android:handle="#+id/sdBottomHandle"
android:orientation="vertical" >
<ImageView
android:id="#+id/sdBottomHandle"
android:layout_width="50dp"
android:layout_height="20dp"
android:background="#drawable/shape_rounded_corners_blue_top"
android:scaleType="center"
android:src="#drawable/icon_arrow_up_white" />
<LinearLayout
android:id="#+id/sdBottomContent"
android:layout_width="match_parent"
android:layout_height="60dp"
android:orientation="vertical"
android:scrollbars="vertical" >
<LinearLayout
android:id="#+id/llBottomNavigation"
android:layout_width="match_parent"
android:layout_height="60dp"
android:orientation="horizontal"
android:scrollbars="horizontal" >
</LinearLayout>
</LinearLayout>
</SlidingDrawer>
And this is my java code:
LinearLayout llBottomNavigation = (LinearLayout) mButtonsView
.findViewById(R.id.llBottomNavigation);
for (int i = 0; i < navigationList.size(); i++) {
TextView tvTab = new TextView(this);
tvTab.setText(Content.getTitle(navigationList.get(i)));
tvTab.setId(i);
tvTab.setTextColor(getResources().getColor(android.R.color.black));
tvTab.setTextSize(12);
if (Hardware.getScreenSize(this) > 4) {
tvTab.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
} else {
tvTab.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
} tvTab.setSingleLine(true);
tvTab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
llBottomNavigation.addView(tvTab);
llBottomNavigation.invalidate();
}
It's not adding any TextViews to the SlidingDrawer. Is there any mistake in my code?
#unflagged.destination , while addView you shoud pass layoutparams with view... try this...
SlidingDrawer slidingDrawer = (SlidingDrawer) findViewById(R.id.slidingDrawer);
LinearLayout llBottomNavigation = (LinearLayout) slidingDrawer.findViewById(R.id.llBottomNavigation);
for (int i = 0; i < 10; i++) {
System.out.println("in loop, " + i);
TextView tvTab = new TextView(this);
tvTab.setText("item "+i);
tvTab.setId(i);
tvTab.setTextColor(getResources().getColor(android.R.color.black));
tvTab.setTextSize(12);
/* if (Hardware.getScreenSize(this) > 4) {
tvTab.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
} else {
tvTab.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
} tvTab.setSingleLine(true);*/
tvTab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
LinearLayout.LayoutParams paramsFortvTab = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
llBottomNavigation.addView(tvTab, paramsFortvTab);
//llBottomNavigation.invalidate();
}
if any query, plz ask...

Crash here now======>sclView.addView(firstLinearLayout, new

edtconversation.setText("");
}
});
}
}
I need that when i click on Button and send message for 2nd time create a new RelativeLayout in LinearLayout for show.(In scrollView)
Error :
AndroidRuntime
MainActivity$1.onClick(MainActivity.java:54)
mmmmm. I recommend that you using from table and you can add programmatically your TextView and etc. simply :
public class MainActivity extends Activity {
String Medtconversation;
EditText edtconversation;
TextView txtviewUser;
TextView txtviewUserT;
RelativeLayout relativeLayout;
LinearLayout firstLinearLayout;
TableRow tr;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edtconversation = (EditText) findViewById(R.id.txtInpuConversation);
Button btn = (Button) findViewById(R.id.btnSend);
final TableLayout tl = (TableLayout) findViewById(R.id.tbl);
final Context context = this;
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Medtconversation = edtconversation.getText().toString();
txtviewUser = new TextView(MainActivity.this);
txtviewUserT = new TextView(MainActivity.this);
txtviewUserT.setText("OK");
txtviewUser.setText(Medtconversation);
tr = new TableRow(context);
tr.addView(txtviewUser);
tr.addView(txtviewUserT);
tl.addView(tr);
edtconversation.setText("");
}
});
}
}
Your XML :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/xxx"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollID"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp" >
<TableLayout
android:id="#+id/tbl"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TableLayout>
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:baselineAligned="true"
android:orientation="horizontal"
android:paddingBottom="5dp"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:weightSum="1" >
<EditText
android:id="#+id/txtInpuConversation"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:hint="Text" >
<requestFocus />
</EditText>
<Button
android:id="#+id/btnSend"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="Click" />
</LinearLayout>
</LinearLayout>
First you need to add the LinearLayout to ScrollView
Then add the relative layout to the LinearLayout
public class MainActivity extends Activity {
String Medtconversation;
EditText edtconversation;
TextView txtviewUser;
LinearLayout rilative;
RelativeLayout relativeLayout;
LinearLayout firstLinearLayout;
ScrollView sclView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edtconversation = (EditText) findViewById(R.id.txtInpuConversation);
Button btn = (Button) findViewById(R.id.btnSend);
sclView = (ScrollView) findViewById(R.id.scrollID);
firstLinearLayout= new LinearLayout(this);
relativeLayout = new RelativeLayout(this);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Medtconversation = edtconversation.getText().toString();
txtviewUser = new TextView(MainActivity.this);
txtviewUser.setText(Medtconversation);
LayoutParams LLParamsT = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
relativeLayout.setLayoutParams(LLParamsT);
relativeLayout.addView(txtviewUser,
new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
firstLinearLayout.setOrientation(LinearLayout.VERTICAL);
LayoutParams LLParams = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
firstLinearLayout.setLayoutParams(LLParams);
sclView.addView(firstLinearLayout);
firstLinearLayout.addView(relativeLayout);
sclView.addView(firstLinearLayout, new
LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
edtconversation.setText("");
}
});
}
}
You are creating a new LinearLayout and RelativeLayout only once (inside onCreate), however you add them multiple times. Instead create new instances from inside of the onClick method:
final Context context = this;
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
LinearLayout firstLinearLayout= new LinearLayout(context);
RelativeLayout relativeLayout = new RelativeLayout(context);
...
firstLinearLayout.addView(relativeLayout);
...
}
});
I have a layout and i need to insert into in some kind of blocks with text - like comments date, name, text. Is there a way to use it like this
for (int r=0; r<10;r++) {
TextView t1=(TextView) findviewbyid(R.id.text1);
t1="BlaBla";
mainlayout.add(commentLayout);
}
So i get something like listview but without adapter and etc.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Name"
android:id="#+id/comm_name"
android:layout_marginLeft="20dp"
android:layout_marginTop="24dp"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Date"
android:id="#+id/comm_date"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_margin="20dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="60dp"
android:layout_marginLeft="20dp"
android:id="#+id/comm_text" />
you can do it, but the way you are doing it will throw an exception, because findViewById returns always the same object, and after the first iteration t1 has already a parent. You should create a new instance of the TextView programmatically, at every iteration.
Try adding views dynamically in linear layout which is inside scroll view.
Try this code.I know it is not exact solution.But,Hope it gives you some idea.
public class MainActivity extends Activity {
ScrollView scrollview;
LinearLayout linearLayout;
LinearLayout.LayoutParams layoutParams;
static int i;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scrollview = (ScrollView)findViewById(R.id.scrollview);
linearLayout = (LinearLayout)findViewById(R.id.linearlayout);
Button button = (Button)findViewById(R.id.button);
layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
button.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
TextView view = new TextView(MainActivity.this);
view.setText(++i+" view");
linearLayout.addView(view, layoutParams);
}
});
}}
Use Following approach
Looping to add dynamically Views to Linear Layout
TextView textView1, textView2;
LinearLayout completeLinearLayout = (LinearLayout) findViewById(R.id.ll);
for (int i = 0; i < 10; i++) {
textView1 = new TextView(Activity.this);
textView2 = new TextView(Activity.this);
String name1 = "xyz";
String name2 = "abc"
completeLinearLayout.addView(textView1);
completeLinearLayout.addView(textView2);
setTextViewParam(textView1, name1);
setTextViewParam(textView2, name2);
}
Method to set TextView Parameters Dynamically
private void setTextViewParam(TextView tv, String text) {
LayoutParams textLayoutParams = new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
textLayoutParams.setMargins(5, 0, 0, 0);
tv.setGravity(Gravity.LEFT);
tv.setText(text);
tv.setTextSize(13);
tv.setTextColor(Color.BLACK);
tv.setLayoutParams(textLayoutParams);
}
Now you can customize the views according to need and container as well.
Happy Coding!!
So, this code works exactlay as i need.
Is there anything wrong with it??
public class InflateView extends Activity {
LinearLayout lLayout;
TextView t,f;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
lLayout = (LinearLayout)findViewById(R.id.layout1);
for (int i=0;i<10;i++)
{
RelativeLayout tv = (RelativeLayout)inflater.inflate(R.layout.text, null);
lLayout.addView(tv);
t = (TextView) tv.findViewById(R.id.ttt);
t.setText("aaaaaaa" + i) ;
f = (TextView) tv.findViewById(R.id.textView);
f.setText(String.valueOf(i));
}
}}
I have designed a layout as in the image below:
After entering text in the EditText, when I press the Add+ Button the TextView and Button will be added as shown in the image below:
I want to show the Button on the right side of the TextView. How should I do this?
Another question, how should I remove corresponding View when user clicks a button? The code:
public class ExampleActivity extends Activity {
private LinearLayout mLayout;
private EditText mEditText;
private Button mButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mLayout = (LinearLayout) findViewById(R.id.linearLayout);
mEditText = (EditText) findViewById(R.id.editText);
mButton = (Button) findViewById(R.id.button);
mButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mLayout.addView(createNewTextView(mEditText.getText()
.toString()));
mLayout.addView(createNewButton());
}
});
}
private TextView createNewTextView(String text) {
final LayoutParams lparams = new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
final TextView textView = new TextView(this);
textView.setLayoutParams(lparams);
textView.setText("New text: " + text);
return textView;
}
private Button createNewButton() {
final LayoutParams lparams = new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
final Button button = new Button(this);
button.setLayoutParams(lparams);
button.setText(" - ");
return button;
}
}
The TextViews and Buttons are stacked because you probably use a LinearLayout with the orientation vertical. You could wrap your TextView + Button into a LinearLayout and then add this LinearLayout to your own layout or you could use a TableLayout like below(I've added some ids so you can delete the rows you want):
public class SomeActivity extends Activity {
private EditText mInput;
private TableLayout mTable;
private static int sCount = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button addButton = (Button) findViewById(R.id.add);
mInput = (EditText) findViewById(R.id.editText1);
mTable = (TableLayout) findViewById(R.id.table1);
addButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mTable.addView(addRow(mInput.getText().toString()));
}
});
}
private TableRow addRow(String s) {
TableRow tr = new TableRow(this);
tr.setId(1000 + sCount);
tr.setLayoutParams(new TableLayout.LayoutParams(
TableLayout.LayoutParams.FILL_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT));
TableRow.LayoutParams tlparams = new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT);
TextView textView = new TextView(this);
textView.setLayoutParams(tlparams);
textView.setText("New text: " + s);
tr.addView(textView);
TableRow.LayoutParams blparams = new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT);
final Button button = new Button(this);
button.setLayoutParams(blparams);
button.setText(" - ");
button.setId(2000 + sCount);
button.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
mTable.removeView(findViewById(v.getId() - 1000));
}
});
tr.addView(button);
sCount++;
return tr;
}
}
where the main layout file is:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="#+id/parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/add"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TableLayout
android:id="#+id/table1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TableLayout>
</LinearLayout>
</ScrollView>
If for some reason, you don't like the TableLayout use a LinearLayout to wrap you TextView and Button with the layout file above(and of course remove the TableLayout):
//...
ll = (LinearLayout) findViewById(R.id.parent);
addButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//where ll is the LinearLayout with the id parent
ll.addView(addRow(mInput.getText().toString()));
}
});
}
private LinearLayout addRow(String s) {
LinearLayout tr = new LinearLayout(this);
tr.setId(1000 + sCount);
tr.setLayoutParams(new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
LinearLayout.LayoutParams tlparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
TextView textView = new TextView(this);
textView.setLayoutParams(tlparams);
textView.setText("New text: " + s);
tr.addView(textView);
LinearLayout.LayoutParams blparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
final Button button = new Button(this);
button.setLayoutParams(blparams);
button.setText(" - ");
button.setId(2000 + sCount);
button.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
ll.removeView(findViewById(v.getId() - 1000));
}
});
tr.addView(button);
sCount++;
return tr;
}
LinearLayout having the property Orientation to align control either Vertically/Horizontally
so just set Orientation of the same
http://developer.android.com/reference/android/widget/LinearLayout.html
mLayout = (LinearLayout) findViewById(R.id.linearLayout);
mLayout.setOrientation(LinearLayout.HORIZONTAL);
Updated

I've arraylist of objects and i need to bind these list of objects to TableLayout at runtime but i didn't get any data into it, please check my code:
XML code:
<TableLayout android:background="#cfe1edFF" android:id="#+id/tl"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TableRow>
<TextView android:text="Symbol"

android:layout_width="wrap_content"
android:layout_weight="1" android:gravity="center" android:background="#drawable/shapefile"/>
<TextView android:text="A/c Type"
android:layout_height="fill_parent" android:textColor="#104e8b"
android:layout_width="wrap_content"
android:layout_weight="1" android:gravity="center" android:background="#drawable/shapefile">
</TextView>
<TextView android:text="Position" android:textColor="#104e8b" android:layout_height="fill_parent"
android:layout_width="wrap_content"
android:layout_weight="1" android:gravity="center" android:background="#drawable/shapefile">

<TableLayout android:id="#+id/score_table"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableRow></TableRow>
</TableLayout>
</ScrollView>
</TableLayout>
so from above TableLayout "score_table" i'm trying to bind data from ArrayList of objects like:
Code to bind table layout using arryalist objects:
public void TableBinding(ArrayList<Position> posLst)
{
TableLayout tLayout=(TableLayout)findViewById(R.id.score_table);
Position pos;
for(int i=0;i<posLst.size();i++)
{
TableRow tr = new TableRow(this);
tr.setId(100+i);
pos=posLst.get(i);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView b = new TextView(this);
b.setText(pos.Symbol);
tr.addView(b);
//b.setId(200+i);
TextView b1 = new TextView(this);
b1.setText(pos.AcType);
tr.addView(b1);
//b1.setId(300+i);
TextView b2 = new TextView(this);
b2.setText(pos.Position);
tr.addView(b2);
//b2.setId(400+i);
/* Add row to TableLayout. */
tLayout.addView(tr,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
}
But i didn't get any data into it, i already checked that ArrayList getting data, please help me.
Thanks,
nag.
You try this way :
ArrayList<String> tablesName = new ArrayList<String>();
TableLayout tl;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tl = (TableLayout) findViewById(R.id.tableLayout1);
for (int i = 0; i < posLst.size(); i++) {
TableRow tr = new TableRow(this);
CheckBox ch = new CheckBox(this);
ch.setId(i);
TextView tv2 = new TextView(this);
tr.addView(ch);
createView(tr, tv2, tablesName.get(i));
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(20, 0, 0, 0);
tr.setPadding(0, 1, 0, 1);
tr.addView(t);
}
try this it worked for me
for (int position=0; position < data.size(); position++)
{
TableRow tableRow= new TableRow(this);
ArrayList<Object> row = data.get(position);
TextView idText = new TextView(this);
idText.setText(pos.Symbol);
tableRow.addView(idText);
TextView textOne = new TextView(this);
textOne.setText(pos.AcType);
tableRow.addView(textOne);
TextView textTwo = new TextView(this);
textTwo.setText(pos.AcType);
tableRow.addView(textTwo);
dataTable.addView(tableRow);
}
}
