HorizontalScrollView automatically moves to right(At the end of the column) when typing in edit text

My problem is the Scroll in a Horizontal ScrollView automatically moves to the right of the screen(End of the column) when typing in a EditText. The problem with this is I can not see what I'm typing in a edit text.
Here's my XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:tag="dasd"
android:id="#+id/linearlayout1">
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:id="#+id/horizontalScrollView" >
<TableLayout android:id="#+id/table_grades" android:layout_height="wrap_content" android:layout_width="wrap_content" >
</TableLayout>
</HorizontalScrollView>
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button

How to rename the checkbox text which is dynamically created in android

In my code, If we need particular number of checkbox or radio button, by giving the count value in EditText, we can get the particular number of checkbox. But It is displaying the checkbox with random alphabets from a to z. But, I need it to change/rename specifically based on my need. Your help is highly appreciated. Thanks in advance. Here is my code.

final TextView textView = new TextView(this);

}

make an String Array like
String[] names = {"Sanket", "Kumar", ......};
then in the code
for (int i = 1; i <= number; i++) {
CheckBox ch = new CheckBox(this);
ch.setId((row * 2) + i);
// Replace the line with
//ch.setText(randomString(3));
// with this line
ch.setText(names[i]);
ll.addView(ch);
}

In your addCheckBox() method, you have set the text of checkbox to randomstring (ch.setText(randomString(3))). Just change this line as your choice just like this ch.setText("Checkbox" + i).

for (int i = 1; i <= number; i++) {
CheckBox ch = new CheckBox(this);
ch.setId((row * 2) + i);
ch.setText(randomString(3)); // Change Here
ll.addView(ch);
}
change the text of checkBox in ch.setText that you want to be

Ok.. I really don't understand... When you create the checkbox you set its text to ch.setText(randomString(3)); Why would you do that if you want specific text ?
Random != Specific.
Just write something like this:
ch.setText("Your desired text");
Or you could create an
String[] checkBoxFruits= {"apple","mango","kiwi"};
and then set the text something like:
for ( int i=0; i<numberOfCheckBoxes; i++ )
{
CheckBox ch = new CheckBox(this);
ch.setId((row * 2) + i);
ch.setText(checkBoxFruits[i]);
ll.addView(ch);
}

public void addCheckBox(int number) {
String[] names = {"Sanket", "Kumar", "Eagle"};
for (int row = 0; row < 1; row++) {
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.HORIZONTAL);
for (int i = 1; i <= number; i++) {
CheckBox ch = new CheckBox(this);
ch.setId((row * 2) + i);
if(i != names.length)
ch.setText(names[i-1]);
else
ch.setText("New name");
ll.addView(ch);
}
((ViewGroup) findViewById(R.id.radiogroup)).addView(ll);
}
}
Use above code.. And check it...

I think you should try using RadioGroup and create an array of strings with which can easily use .setText method to run a loop throgh all the Radio Buttons.

How to add items in a table from EditTexts in Android?

(SOLVED) -- Removed layout params on each view ---
I am new to Android and I am trying to add rows in a TableLayout from the items that I entered in text fields.

tableRow.addView(tvContactNo);
tableLayout.addView(tableRow, new TableLayout.LayoutParams(

}
});
}
}
I could see in the debugger that the values from my views were added in my tableRow but I don't see the table appearing in my screen, what am I missing or doing wrong?
Any help would be greatly appreciated.
Thanks!

I guess the height of screen is increased. Try using Scrollview on top of this layout.

I think you have to change RelativeLayout property android:height="wrap_content" instead of android:height="fill_parent" and also do for TableLayout
May this work for you...
Try this:
Edited:
public static class ContactsFragment extends Fragment {
#Override

Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_section_contacts,
container, false);

Button contactButton = (Button) rootView.findViewById(R.id.addContact);
final TableLayout tableLayout = (TableLayout) rootView.findViewById(R.id.contactsTableLayout);
final EditText txtContactName = (EditText) rootView.findViewById(R.id.contactName);
final EditText txtContactRelationship = (EditText) rootView.findViewById(R.id.contactRelationship);
final EditText txtContactAddress = (EditText) rootView.findViewById(R.id.contactAddress);
final EditText txtContactPhoneNo = (EditText) rootView.findViewById(R.id.contactPhoneNo);

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

After creating Layout Then First You need to retrieve the json data
then store it in the String[] assign the values to the table according
to your requirement.For example go through the following.
Activity :-
public class ProvisionActivity extends Activity {
private TableLayout mTable;
private static int sCount = 0;
Button btnAdd;
String[] pnames = { "provision1", "provision2", "provision3", "provision4",
"provision5" };
String[] pprice = { "45", "85", "125", "15", "198" };
StringBuffer xpenses;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnAdd = (Button) findViewById(R.id.button1);
mTable = (TableLayout) findViewById(R.id.tableprovision);
xpenses = new StringBuffer();
btnAdd.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mTable.addView(addRow(pnames, pprice));
for (int i = 0; i < mTable.getChildCount(); i++) {
mTable.getChildAt(i);
System.out.println("Table Row values are "
+ mTable.getChildAt(i));
xpenses = xpenses.append(mTable.getChildAt(i).toString());
System.out
.println("Expense Table Values Are After Storing it in a String variable "
+ xpenses);
}
}
});
}
private TableRow addRow(String[] sname, final String[] sprice) {
TableRow tr = new TableRow(this);
tr.setId(1000 + sCount);
tr.setLayoutParams(new TableLayout.LayoutParams(
TableLayout.LayoutParams.FILL_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT));
TableRow.LayoutParams blparams = new TableRow.LayoutParams(150, 35);
final Spinner spinner = new Spinner(this);
spinner.setLayoutParams(blparams);
spinner.setBackgroundColor(Color.DKGRAY);
ArrayAdapter<String> xtypeadapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_dropdown_item, sname);
spinner.setAdapter(xtypeadapter);
tr.addView(spinner);
TableRow.LayoutParams tlparams = new TableRow.LayoutParams(55,
TableLayout.LayoutParams.WRAP_CONTENT);
final TextView textView = new TextView(this);
textView.setLayoutParams(tlparams);
textView.setTextColor(Color.BLACK);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
textView.setText(" "
+ sprice[spinner.getSelectedItemPosition()]);
}
public void onNothingSelected(AdapterView<?> arg0) {
}
});
tr.addView(textView);
TableRow.LayoutParams blparams1 = new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT);
final Button button = new Button(this);
button.setLayoutParams(blparams1);
button.setBackgroundColor(Color.LTGRAY);
button.setText(" - ");
button.setId(2000 + sCount);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mTable.removeView(findViewById(v.getId() - 1000));
}
});
tr.addView(button);
sCount++;
return tr;
}
}
