i tried to change the height and width of the all layout used in the particular screen but nothing is changed can anyone help me to fix this.
this is my xml file.

Try giving layout params to every row you add dynamically and update your init() function like below:
#SuppressLint("ResourceType")
public void init() {
TableLayout stk = (TableLayout) findViewById(R.id.table_main);
TableRow tbrow0 = new TableRow(this);
//added layout params and weight
tbrow0.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT, 1.0f));
TextView tv0 = new TextView(this);
tv0.setText(" Name ");//date
tv0.setTextColor(Color.WHITE);
//added layout params and weight
tv0.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT, 1.0f));
tbrow0.addView(tv0);
TextView tv1 = new TextView(this);
tv1.setText(" Date ");//name
tv1.setTextColor(Color.WHITE);
//added layout params and weight
tv1.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,

And provide android:fillViewport="true" to your ScrollView with id=scrollView1 and HorizontalScrollView with id=hscrll1

Dynamicaly add layout in layout?

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));
}
}}

Adding Table rows Dynamically in Android

I am trying to create a layout where I need to add table rows dynamically. Below is the table layout xml
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/displayLinear"
android:background="#color/background_df"
android:orientation="vertical" >
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/display_row"
android:layout_marginTop="280dip" >
</TableLayout>
The activity file where rows are being added dynamically is
public void init(){
menuDB = new MenuDBAdapter(this);
ll = (TableLayout) findViewById(R.id.displayLinear);
TableRow row=(TableRow)findViewById(R.id.display_row);
for (int i = 0; i <2; i++) {
checkBox = new CheckBox(this);
tv = new TextView(this);
addBtn = new ImageButton(this);
addBtn.setImageResource(R.drawable.add);
minusBtn = new ImageButton(this);
minusBtn.setImageResource(R.drawable.minus);
qty = new TextView(this);
checkBox.setText("hello");
qty.setText("10");
row.addView(checkBox);
row.addView(minusBtn);
row.addView(qty);
row.addView(addBtn);
ll.addView(row,i);
}
}
But when I run this, I am getting below error
08-13 16:27:46.437: E/AndroidRuntime(23568): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.roms/com.example.roms.DisplayActivity}: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
I understand that this is due to command ll.addView(row,i); but when I remove this its adding all stuff in a single row rather tan creating a new row for next item. I tried with giving index too as row.addView(addBtn,i) but still its not populating correctly. Please advise. Thanks.

Create an init() function and point the table layout.
Then create the needed rows and columns.
public void init() {
TableLayout stk = (TableLayout) findViewById(R.id.table_main);
TableRow tbrow0 = new TableRow(this);
TextView tv0 = new TextView(this);
tv0.setText(" Sl.No ");
tv0.setTextColor(Color.WHITE);
tbrow0.addView(tv0);
TextView tv1 = new TextView(this);
tv1.setText(" Product ");
tv1.setTextColor(Color.WHITE);
tbrow0.addView(tv1);
TextView tv2 = new TextView(this);
tv2.setText(" Unit Price ");
tv2.setTextColor(Color.WHITE);
tbrow0.addView(tv2);
TextView tv3 = new TextView(this);
tv3.setText(" Stock Remaining ");
tv3.setTextColor(Color.WHITE);
tbrow0.addView(tv3);
stk.addView(tbrow0);
for (int i = 0; i < 25; i++) {
TableRow tbrow = new TableRow(this);
TextView t1v = new TextView(this);
t1v.setText("" + i);
t1v.setTextColor(Color.WHITE);
t1v.setGravity(Gravity.CENTER);
tbrow.addView(t1v);
TextView t2v = new TextView(this);
t2v.setText("Product " + i);
t2v.setTextColor(Color.WHITE);
t2v.setGravity(Gravity.CENTER);
tbrow.addView(t2v);
TextView t3v = new TextView(this);
t3v.setText("Rs." + i);
t3v.setTextColor(Color.WHITE);
t3v.setGravity(Gravity.CENTER);
tbrow.addView(t3v);
TextView t4v = new TextView(this);
t4v.setText("" + i * 15 / 32 * 10);
t4v.setTextColor(Color.WHITE);
t4v.setGravity(Gravity.CENTER);
tbrow.addView(t4v);
stk.addView(tbrow);
}
}
Call init function in your onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
init();
}
Layout file like:
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#3d455b"
android:layout_alignParentLeft="true" >
<HorizontalScrollView
android:id="#+id/hscrll1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_gravity="center"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TableLayout
android:id="#+id/table_main"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" >
</TableLayout>
</RelativeLayout>
</HorizontalScrollView>
</ScrollView>
Will look like:

You shouldn't be using an item defined in the Layout XML in order to create more instances of it. You should either create it in a separate XML and inflate it or create the TableRow programmaticaly. If creating them programmaticaly, should be something like this:
public void init(){
TableLayout ll = (TableLayout) findViewById(R.id.displayLinear);
for (int i = 0; i <2; i++) {
TableRow row= new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(lp);
checkBox = new CheckBox(this);
tv = new TextView(this);
addBtn = new ImageButton(this);
addBtn.setImageResource(R.drawable.add);
minusBtn = new ImageButton(this);
minusBtn.setImageResource(R.drawable.minus);
qty = new TextView(this);
checkBox.setText("hello");
qty.setText("10");
row.addView(checkBox);
row.addView(minusBtn);
row.addView(qty);
row.addView(addBtn);
ll.addView(row,i);
}
}

You also can, as Fredigato said, declare a RelativeLayout in a separate Layout file. Then instantiate it using:
for(int i = 0; i < 6; i ++){
LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout row = (RelativeLayout) inflater.inflate(R.layout.table_view,null);
quizesTableLayout.addView(row,i);
}
In this approach you can easily design one custom row using XML and reuse it.
Now, to be able to change the children views in the instantiated RelativeLayout. You can call row.childAt(index).
So lets say you have a TextView in the RelativeLayout, you can use:
TextView tv = (TextView) row.childAt(0);
tv.setText("Text");

change code of init like following,
public void init(){
menuDB = new MenuDBAdapter(this);
ll = (TableLayout) findViewById(R.id.displayLinear);
ll.removeAllViews()
for (int i = 0; i <2; i++) {
TableRow row=(TableRow)findViewById(R.id.display_row);
checkBox = new CheckBox(this);
tv = new TextView(this);
addBtn = new ImageButton(this);
addBtn.setImageResource(R.drawable.add);
minusBtn = new ImageButton(this);
minusBtn.setImageResource(R.drawable.minus);
qty = new TextView(this);
checkBox.setText("hello");
qty.setText("10");
row.addView(checkBox);
row.addView(minusBtn);
row.addView(qty);
row.addView(addBtn);
ll.addView(row,i);
}

Activity
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<TableLayout
android:id="#+id/mytable"
android:layout_width="match_parent"
android:layout_height="match_parent">
</TableLayout>
</HorizontalScrollView>
Your Class
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_testtable);
table = (TableLayout)findViewById(R.id.mytable);
showTableLayout();
}
public void showTableLayout(){
Date date = new Date();
int rows = 80;
int colums = 10;
table.setStretchAllColumns(true);
table.bringToFront();
for(int i = 0; i < rows; i++){
TableRow tr = new TableRow(this);
for(int j = 0; j < colums; j++)
{
TextView txtGeneric = new TextView(this);
txtGeneric.setTextSize(18);
txtGeneric.setText( dateFormat.format(date) + "\t\t\t\t" );
tr.addView(txtGeneric);
/*txtGeneric.setHeight(30); txtGeneric.setWidth(50); txtGeneric.setTextColor(Color.BLUE);*/
}
table.addView(tr);
}
}

You can use an inflater with TableRow:
for (int i = 0; i < months; i++) {
View view = getLayoutInflater ().inflate (R.layout.list_month_data, null, false);
TextView textView = view.findViewById (R.id.title);
textView.setText ("Text");
tableLayout.addView (view);
}
Layout:
<TableRow
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_centerInParent="true"
android:gravity="center_horizontal"
android:paddingTop="15dp"
android:paddingRight="15dp"
android:paddingLeft="15dp"
android:paddingBottom="10dp"
>
<TextView

I am trying the above code with modification as per my requirement. The table is created properly. Bu the problem is when I am opening the activity 1st time, the table is not displaying. It is displaying 2nd time only.
My code is
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getSupportActionBar().hide();
setContentView(R.layout.activity_aggre_ascendingorder);
drawerLayout = findViewById(R.id.drawer_layout);
init();
}
#SuppressLint("ResourceType")
public void init() {
stk = (TableLayout) findViewById(R.id.table_main);
TableRow tbrow0 = new TableRow(this);
TextView tv0 = new TextView(this);
tv0.setText("Actual Values ");
tv0.setWidth(330);
tv0.setGravity(Gravity.CENTER);
tv0.setTextColor(Color.WHITE);
tv0.setTextSize(12);
tv0.setBackgroundResource(R.drawable.border4);
tbrow0.addView(tv0);
TextView tv1 = new TextView(this);
tv1.setText("Meter Values ");
tv1.setWidth(330);
tv1.setGravity(Gravity.CENTER);
tv1.setTextColor(Color.WHITE);
tv1.setTextSize(12);
tv1.setBackgroundResource(R.drawable.border4);
tbrow0.addView(tv1);
TextView tv2 = new TextView(this);
tv2.setText("Error ");
tv2.setWidth(315);
tv2.setGravity(Gravity.CENTER);
tv2.setTextColor(Color.WHITE);
tv2.setTextSize(12);
tv2.setBackgroundResource(R.drawable.border4);
tbrow0.addView(tv2);
Intent z = getIntent();
input1 = z.getIntExtra(EDIT, 1);
input2 = z.getIntExtra(TEXT, 1);
if (input2 == 0) {
x = 400;
} else {
x = input1 / input2;
}
stk.addView(tbrow0);
try {
for (int i = 0; i < x + 1; i++) {
TableRow tbrow = new TableRow(this);
final EditText t1v = new EditText(this);
t1v.setId(1);
if (input2 == 0) {
t1v.setHint("");
} else {
t1v.setText("" + i * input2);
}
final EditText t2v;
TextView t3v = null;
t1v.setTextColor(Color.BLACK);
t1v.setGravity(Gravity.CENTER);
t1v.setTextSize(12);
t1v.setInputType(InputType.TYPE_CLASS_NUMBER);

}
//t1v.setText(stb.split(",")[0]);
t2v.setText(stb.split(",")[1]);
t3v.setText(stb.split(",")[2]);
tbrow.addView(t1v);
tbrow.addView(t2v);
tbrow.addView(t3v);

Can you clear me what is the mistake I am doing on this

Unable to dynamically set image in an ImageView inside a TableRow

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)

How to horizontally align some programmatically added views?

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
<?xml version="1.0" encoding="utf-8"?>
