Cannot show first Data from Date

Cannot show first Data from Date - java

i have some question about showing data from database sqlite.
if i want to show data from date like startdate and enddate. example from between 01/01/2014 and 03/01/2014. why the data only show from 02/01/2014 - 03/01/2014? where data from 01/01/2014?
and if want to show data from between 01/01/2014 and 01/01/2014, the data cannot show?
Here the program that i have :

and this the database adapter :

ArrayList<ArrayList<Object>>();
Cursor cur;
try{

if(!cur.isAfterLast()){
do{

dataList.add(cur.getLong(0));
dataList.add(cur.getString(1));
dataList.add(cur.getString(2));
dataList.add(cur.getString(3));
dataArray.add(dataList);
}while (cur.moveToNext());
}

e.printStackTrace();
Log.e("DB ERROR", e.toString());
Toast.makeText(context, "Gagal Ambil Date Baris: "+e.toString(), Toast.LENGTH_SHORT).show();
}
return dataArray;
}
and this java program :
protected void updateTable(){
while (table4data.getChildCount() > 1){
table4data.removeViewAt(1);
}
String startDate = DateText1.getText().toString();
String endDate = DateText2.getText().toString();
ArrayList<ArrayList<Object>> data = logstatsdatabase.ambilBarisDate(startDate, endDate);
for (int posisi = 0; posisi < data.size(); posisi++){
TableRow tabelBaris = new TableRow(this);
ArrayList<Object> baris = data.get(posisi);
TextView idTxt = new TextView(this);
idTxt.setText(baris.get(0).toString());
tabelBaris.addView(idTxt);
TextView dateTxt = new TextView(this);
dateTxt.setText(baris.get(1).toString());
tabelBaris.addView(dateTxt);
TextView timeTxt = new TextView(this);
timeTxt.setText(baris.get(2).toString());
tabelBaris.addView(timeTxt);
TextView statusTxt = new TextView(this);
statusTxt.setText(baris.get(3).toString());
tabelBaris.addView(statusTxt);
table4data.addView(tabelBaris);
}
}

Let you have a set of number 1-100. And then you say between(30-60), it will return you 31,32....58,59. If you want to include 30 and 60 in your range, you should call between(29,61). I think this answers the 1st part of your query.
The second part, between(1,1) will always be null. So in your case, if yo wish to fetch some events for a particular day between 01/01/2014 and 01/01/2014:
You can ommit the use of between operator and use equals operator in this case
Or else store your date in a LONG foramt using Calendar.getInstance().getTimeInMilis(). Then you can use between operation more precisely to include the time range as well.

How to RadioButton get selected

I have an API and there is a value of broadcast and the options are public, private, logged in and unlisted. I want a radiobutton to be selected itself as public if broadcast is public.
This is my XML code:
<TextView
android:textColor="#060606"
android:layout_marginTop="10dp"
android:textSize="15sp"
android:text="Broadcast Options"
android:id="#+id/broadcast_head"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RadioGroup
android:orientation="vertical"
android:id="#+id/radio_group_broadcast"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:textSize="16sp"
android:text="Public"
android:id="#+id/radio_button_public"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RadioButton
android:textSize="16sp"
android:text="Private"
android:id="#+id/radio_button_private"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RadioButton
android:textSize="16sp"
android:text="Unlisted"
android:id="#+id/radio_button_unlisted"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<RadioButton
android:textSize="16sp"
android:text="Logged Only"
android:id="#+id/radio_button_logged_only"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RadioGroup>
</TextView>
and this is my Java code;
I don't know whether this code is correct or not.
rbPub = (RadioButton)findViewById(R.id.radio_button_public);
rbPri = (RadioButton)findViewById(R.id.radio_button_private);
rbUnl = (RadioButton)findViewById(R.id.radio_button_unlisted);
rbOnl = (RadioButton)findViewById(R.id.radio_button_logged_only);
radioGroup1 = (RadioGroup) findViewById(R.id.radio_group_broadcast);
VideoDetail videoDetailBroadcast = null; //this is the problem, can't fix(null)
if (videoDetailBroadcast.isPublic()) {
rbPub.setChecked(true);
}
else if (videoDetailBroadcast.isPrivate()) {
rbPri.setChecked(true);
}
else if (videoDetailBroadcast.isUnlisted()) {
rbUnl.setChecked(true);
}
else if (videoDetailBroadcast.isLoggedOnly()) {
rbOnl.setChecked(true);
}

You should should initialize videoDetailBroadcast that way : VideoDetail videoDetailBroadcast = new VideoDetail()

getText() returns empty string (android studio)

I have a little question here about android development.
I already searched on internet, but i still can't find the solution.
I want to getText() from a view, but it just returns an empty ("") string.
Here's my .java code:
public void kotakCentang(View view)
{
RelativeLayout vwParentRow = (RelativeLayout)view.getParent();
TextView id_test = (TextView)vwParentRow.getChildAt(0);
TextView nama_test = (TextView)vwParentRow.getChildAt(1);
tugas_status = (TextView)vwParentRow.getChildAt(5);
tanggalKasih = (EditText)vwParentRow.getChildAt(6);
tanggalKumpul = (EditText)vwParentRow.getChildAt(8);
waktuKasih = (EditText)vwParentRow.getChildAt(7);
waktuKumpul = (EditText)vwParentRow.getChildAt(9);
tugasKompleksitas = (EditText)vwParentRow.getChildAt(10);
Tugas tugas = new Tugas();
TugasRepo tugass = new TugasRepo(this);
tugas.nama = nama_test.getText().toString();
tugas.waktuDikasih = waktuKasih.getText().toString();
tugas.waktuDikumpul = waktuKumpul.getText().toString();
tugas.tanggalDikasih = tanggalKasih.getText().toString();
tugas.tanggalDikumpul = tanggalKumpul.getText().toString();
tugas.kompleksitas=Integer.parseInt(tugasKompleksitas.getText().toString());
tugasKompleksitas.getText().toString();
}
The getText() which returns empty string is just the tugas.waktuDikasih, and tugas.waktuDikumpul .
Thank you for your help.

Widget click not responding

I'm trying to set to all of the views that are in the widget a click listener that should open an activity upon a click, but for now seems that its not working. Can someone tell me what am I doing wrong?
Here is my code:
public class AthanWidget extends AppWidgetProvider {
private SharedPreferences prefs;
private boolean PAID = false;
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
final int N = appWidgetIds.length;

// Perform this loop procedure for each App Widget that belongs to this
// provider
for (int i = 0; i < N; i++) {
int appWidgetId = appWidgetIds[i];
// Create an Intent to launch ExampleActivity
Intent intent;
if (!PAID) {
intent = new Intent(context, RemoveAds.class);
} else {
intent = new Intent(context, Main.class);
}
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
// Get the layout for the App Widget and attach an on-click listener
// to the button

here you are setting click pending intent for the appwidgetId, but that should be view id.
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
views.setOnClickPendingIntent(appWidgetId, pendingIntent);
like:
if the id of a Button is R.id.button1. which is in widget layout if you want to set click listener to that button. then that should be like this :
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
views.setOnClickPendingIntent(R.id.button1, pendingIntent);

Error when generating dynamic content

I'm trying to generate form elements from a template when the user clicks on a button. I created the template and the container layout for the new forms with XML. Its successfully generating the first form where I'm telling it to generate, but when I try to generate more forms beyond the first one its giving me an error: "the specified child already has a parent. You must call removeView() on the child's first parent". Any clue as to what I should do so as to generate more than one element? I've tried changing the id of the newly created forms but that's giving me a null pointer exception and crashing. Thank you.
public class MakeQuestion extends Activity implements OnClickListener{
private static final int MY_BUTTON = 9000;
int templateID = 1;
Button b;
Button target;
View insertPoint;
Button testTemplate;
View v1;
RelativeLayout.LayoutParams templateParams;
LayoutInflater vi;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.make_question);
Initialize();
}
public void Initialize(){
//button for adding new forms
b = (Button) findViewById(R.id.makeLayoutButton);
b.setOnClickListener(this);
//get the template form to be duplicated
vi = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v1 = vi.inflate(R.layout.form_template, null);
//set the params for the element that will have dynamically generated content below it
templateParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
//container where forms will be contained in
insertPoint = findViewById(R.id.questionsContainer);
//view where new form will go below
View belowContainer = findViewById(R.id.questionTemplateFake);
//set id for layout params of view
belowContainer.setId(1);
//set rule for new forms to go below view 'belowContainer'
templateParams.addRule(RelativeLayout.BELOW, belowContainer.getId());
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.makeLayoutButton:
v1 = vi.inflate(R.layout.form_template, null);
//add view to the insertPoint
((LinearLayout) insertPoint).addView(v1);
break;
}
}
}
Added forms should go in "questionsContainer" which is set to be below "questionTemplateFake"

You are trying to add the same instance over and over again. Thus the message that "specific child already exists". You would have to create a new template layout instance with different ID (I suppose) and then try to add it in.
So rather than:
((RelativeLayout) insertPoint).addView(v1, templateParams);
and adding v1 again. Create a new instance
v1 = vi.inflate(R.layout.form_template, null);
set the id for good measures and then add it again in view.
I suppose you don't need to set the id, but you can read more about how id's work here

One of the logs when the program fails:
04-26 20:39:33.174: E/AndroidRuntime(16092): Caused by: java.lang.ClassCastException: android.widget.TextView
04-26 20:39:33.174: E/AndroidRuntime(16092): at calc.ulater.QuadCalcActivity.SolveOnClick(QuadCalcActivity.java:31)
I believe this has something to do with the decimal text boxes. The program worked well before I made them only take decimal numbers, but it also worked a time or two after. I'd rather not show the rest of my code, unless you guys are sure the problem lies there.

If this is the line that's screwing up:
EditText b = (EditText)findViewById(R.id.bValue);
Then its saying you're trying to cast a TextView to an EditText.
What's line 31? That one?

EditText a = (EditText)findViewById(R.id.aValue);
EditText b = (EditText)findViewById(R.id.bValue); //screws up somewhere here
EditText c = (EditText)findViewById(R.id.cValue);
equation = (TextView)findViewById(R.id.equationText);
answer11 = (TextView)findViewById(R.id.answer1);
answer12 = (TextView)findViewById(R.id.answer2);
or1 = (TextView)findViewById(R.id.or1);
or2 = (TextView)findViewById(R.id.or2);
all the initialization must be done in onCreate() and not in the constructor
Updated::
EditText a = (EditText)view.findViewById(R.id.aValue);
EditText b = (EditText)view.findViewById(R.id.bValue); //screws up somewhere here
EditText c = (EditText)view.findViewById(R.id.cValue);
equation = (TextView)view.findViewById(R.id.equationText);
answer11 = (TextView)view.findViewById(R.id.answer1);
answer12 = (TextView)view.findViewById(R.id.answer2);
or1 = (TextView)view.findViewById(R.id.or1);
or2 = (TextView)view.findViewById(R.id.or2);
if view is your parent view
