In my app, the user inputs a number (in this case, the number of reactants in a chemical equation, so the number of starting materials) and as a result a number of boxes, the amount matching that of the number given by the user, are produced/spawned/created below after pressing a button.
How do I go about doing this? I thought a for-loop would come into play, so I started it off.
Here's the Java class:
public class EquationBalancer extends Activity {
final EditText reactantNumberField = (EditText) findViewById(R.id.reactantsNumber);
final int reactantNom = Integer.parseInt(reactantNumberField.getText().toString());
HorizontalScrollView reactants = (HorizontalScrollView) findViewById(R.id.reactants);
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.balancelayout);
Button setReactantsNo = (Button) findViewById(R.id.reactantsNumberOk);
setReactantsNo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
for (int i = 1; i < reactantNom; i++) {
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.balancelayout, menu);
return true;
}
}
and the XML layout:
<RelativeLayout
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" >
<TextView
android:id="#+id/reactantsHowMany"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="10dp"
android:text="#string/reactantsHowMany"
android:textSize="18dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<EditText
android:id="#+id/reactantsNumber"
android:paddingTop="5dp"
android:layout_width="65dp"
android:layout_height="wrap_content"
android:layout_below="#id/reactantsHowMany"
android:layout_marginLeft="60dp"
android:inputType="number"
android:hint="e.g. 4" />
<Button
android:id="#+id/reactantsNumberOk"
android:paddingTop="5dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/reactantsHowMany"
android:layout_alignParentRight="true"
android:layout_marginRight="60dp"
android:layout_alignBottom="#id/reactantsNumber"
android:text="Set" />
<HorizontalScrollView
android:id="#+id/reactants"
android:paddingTop="5dp"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_below="#id/reactantsNumber" >
</HorizontalScrollView>
</RelativeLayout>
for (int i = 1; i < reactantNom; i++) {
EditText editText=new EditText(this);
editText.setText("some text if you want else remove this line");
reactants.addView(editText);
}
and if you want to get data from these edittext some where else in your code then maintain an array of edittext and save these edittext objects in that array..,.
Try this..,.

How to get value from dynamically created EditText in Android?
This is my dynamic view (XML file)
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:id="#+id/et_waypoint"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/background"
android:hint="Way Points"
android:padding="10dp"
android:textSize="16sp" />
<Button
android:id="#+id/btn_waypoint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Find" />
</LinearLayout>
And I am using LayoutInflater because I want perfect Designed layout which is not accomplish by me via setLayoutParams so this is the reason I am using LayoutInflater.
And here is my code:
LayoutInflater l = getLayoutInflater();
final LinearLayout mainActivity = (LinearLayout) findViewById(R.id.dynamic);
final View view = l.inflate(R.layout.dynamic_layout_waypoints, null);
buttonWayPoints = (Button) view.findViewById(R.id.btn_waypoint);
editTextWayPoints = (EditText) view.findViewById(R.id.et_waypoint);
mainActivity.addView(editTextWayPoints);
I am new to Android. Most of people suggest this solution but it's not worked for me, the issue is when I implement this code my ADD NEW EDIT TEXT BUTTON not respond me.
This is how I am trying to get inserted value but it returns value of only last created edit text:
public Cursor getPerson(String Query) {
SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery(Query, null);
return c;
}
sb is StringBuilder sb;, w is String w;
String queryWayPoints = "select * from route_table where trip_id = " + t;
Cursor s = myDb.getPerson(queryWayPoints);
int count3 = s.getCount();
for (int j = 0; j < count3; j++) {
s.moveToNext();
w = s.getString(s.getColumnIndex("waypoints"));
// se.append(w + "." + "00");
}
trip_name.setText(n);
trip_date.setText(d);
sb.append(w);
}
trip_route.setText(sb.toString());
Although, I didn't get what exactly your question is, still I'll try to help.
What exactly this code does is, on clicking the button on top an new layout(one that you wanted) will add to the activity screen at runtime, i.e an edittext with a button, and when you click on that button, A toast with the value of respective edittext will be shown. Hence solving the problem of getting the value of dynamically added edittext

There are some problems with your code. You're trying to add editTextWayPoints to mainActivity, but editTextWayPoints already has a parent, which is view. I think you should be adding view to mainActivity (mainActivity.addView(view)). Finally, to access the value of editTextWayPoints, you simply do editTextWayPoints.getText().toString();
I have array in xml and I am trying to get a particular element from array using its number from user input but my app is crashing when click on button.

int b = Integer.valueOf(editText.getText().toString());
// Check the number is within range
if (b >= 0 && b < (myArray.length - 1)) {

}
You should probably also make sure you set the input type for your EditText as number in your layout xml.
<EditText
android:id="#+id/editText"
...
android:inputType="number"/>
Additional:
As per my comments under your question "remove onClick from the EditText".
Your final EditText definition should look something like this:
<EditText
android:id="#+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/button4"
android:layout_toRightOf="#+id/button4"
android:inputType="number"/>
The most important thing is removing android:onClick="press" from the EditText.
When you run it, enter your number in the edit text and then press button4 (which you have labeled "New Button". The required string is then correctly shown in the TextView.
I have tested your code, copy/pasting it exactly as it is, and only changed the `EditText' as described, and created a dummy string-array in xml for testing. It works fine. If you are still having problems, provide some more description of what is happening.
In order to get an array from resource, do this somewhere within your onCreate():
ArrayList<String> yourArray;
yourArray = getResources().getStringArray(R.array.your_array_name_in_xml);
After that, you could just call yourArray.get(index) to get its content.
Given that, you could do this in order to get what you want:
int index = Integer.parseInt(yourEditText.getText().toString());
String textFromArray = yourArray.get(index);
yourTextView.setText(textFromArray);
I am facing one issue while using customRangeSeekBar in android when rangeseekbar movies based on Edittext values my RangeSeekbar values Startingvalue startingvalue 0 and endingvalue 30

I used custom RangeSeekbar class like
RangeSeekBar.java
this class is developed based on this link
and finally my activity class is
MainActivity2.java
public class MainActivity2 extends Activity

TextView start,end;
EditText edt_starttime,edt_endtime;
String url,edt_starttime1;

edt_starttime=(EditText)findViewById(R.id.edt_starttime);
edt_endtime=(EditText)findViewById(R.id.edt_endtime);
edt_starttime = (EditText) findViewById(R.id.edt_starttime);
// edittext listenr starts...........
// editettxt start listener ends.........
//editetxt end listener starts..............
edt_endtime.setOnEditorActionListener(new OnEditorActionListener()
{
#Override

{
// TODO Auto-generated method stub
if (actionId == EditorInfo.IME_ACTION_DONE)
{
Log.e("Ram san","jhgkfdjgh");
String edt_endtime1=edt_endtime.getText().toString();
if(edt_endtime1.length()!=0)
{
minValue1=Integer.parseInt(edt_endtime1);
Log.e("", ""+minValue1);
}
return true; // consume.
}
// pass on to other listeners.
return false;
}
});
//edittext listeners ends.................
// create RangeSeekBar as Integer range between 20 and 75
RangeSeekBar<Integer> seekBar = new RangeSeekBar<Integer>(0, 30, MainActivity2.this);
seekBar.setLeft(25);
seekBar.setOnRangeSeekBarChangeListener(new OnRangeSeekBarChangeListener<Integer>()
{
#Override
public void onRangeSeekBarValuesChanged(RangeSeekBar<?> bar, final Integer minValue, Integer maxValue)
{
edt_starttime.setText(""+minValue);
edt_endtime.setText(""+maxValue);
Log.e("values ", ""+ minValue + ", MAX=" + maxValue);
}
});
// add RangeSeekBar to pre-defined layout
ViewGroup layout = (ViewGroup) findViewById(R.id.layout);
// layout.setP
layout.addView(seekBar);
}
//onCreate() ends.................
}
How can I set EditText values to the RangeSeekbar when edittext values are based on moving the rangeseekbar?
Am trying to use radio button group widget to select gender in my application. Now here is the thing. The user will select a gender and on clicking the button the user will be guided to the respective activity. I wrote the code . The second problem is that my program does nothing though am launching new activities in the if part. I debugged my program to see if the if condition is satisfied seems to me it does. Here is the xml and the .java file
public class Gender extends Activity{
private RadioGroup radioSexGroup;
private RadioButton radioSexButton;
private Button btnDisplay;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gender_asking);
addListenerOnButton();
}
public void addListenerOnButton() {
radioSexGroup = (RadioGroup) findViewById(R.id.radioSex);
btnDisplay = (Button) findViewById(R.id.gender_button);
btnDisplay.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//****************************
int selectedId = radioSexGroup.getCheckedRadioButtonId();
// find the radiobutton by returned id
radioSexButton = (RadioButton) findViewById(selectedId);
if("Iam a Guy!".equals(radioSexButton.getText()))
{
Intent male_activity = new Intent(Gender.this, Meter.class);
startActivity(male_activity);
}
if("Iam a Girl!".equals(radioSexButton.getText()))
{
Intent male_activity = new Intent(Gender.this, For_Girl.class);
startActivity(male_activity);
}
//********************************
}
});
}
}

First of all, don't rely on the text of a View in this situation. If you decide to change it later then it will create problems. Most likely, you won't change the id of it so just use that. Change it to something like this
btnDisplay.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
int selectedId = radioSexGroup.getCheckedRadioButtonId(); / get the id
switch (selectedId) // switch on the button selected
{
case R.id.radioMale:
Intent male_activity = new Intent(Gender.this, Meter.class);
startActivity(male_activity);
break;
case R.id.radioFemale:
Intent male_activity = new Intent(Gender.this, For_Girl.class);
startActivity(male_activity);
break;
default:
Toast.makeText(v.getContext(), "No gender selected",
Toast.LENGTH_SHORT).show();
break;
}
//********************************
}
});
