Can anyone help please? When click on the quiz button the application will close. I want it to go to quiz page which called HomeScreen.java

looks good to me, did u declare the second activity in the manifest file? :
<activity android:name="HomeScreen"/>
If that doesn't work, use some break points and the debugger, hope it helps.

ListView doesn't show whole ArrayList

I have created admin_content.xml layout and put ListView in that layout. There is also a button to add new list item to that ListView. This layout's java file is AdminContent.java and I created my adapter inside this file. When I click to "Add" button it goes to add_school_info.xml layout and I get the information from this layout with Bundle class and send it to my AdminContent.java file. However, when I add new school info, it only shows last entry. Here is what I have done so far:

AdminTab.java: This file is getting data from EditText fields and send it to my AdminContent.java file via Bundle class.
package com.example.android.students;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class AdminTab extends Activity {
private EditText editFaculty, editDepartment, editAdvisor;
private Button clearInfo, cancelInfo, addInfo;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.add_school_info);
addClickListener();
}
public void addClickListener() {
final Context context = this;
addInfo = (Button) findViewById(R.id.addInfo);
clearInfo = (Button) findViewById(R.id.clearInfo);
cancelInfo = (Button) findViewById(R.id.cancelInfo);
editFaculty = (EditText) findViewById(R.id.editFaculty);
editDepartment = (EditText) findViewById(R.id.editDepartment);
editAdvisor = (EditText) findViewById(R.id.editAdvisor);
addInfo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, AdminContent.class);
String faculty = editFaculty.getText().toString();
String department = editDepartment.getText().toString();
String advisor = editAdvisor.getText().toString();
Bundle bundle = new Bundle();
bundle.putString("Faculty", faculty);
bundle.putString("Department", department);
bundle.putString("Advisor", advisor);
intent.putExtras(bundle);
startActivity(intent);
}
});
clearInfo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
editFaculty.setText(null);
editDepartment.setText(null);
editAdvisor.setText(null);
}
});
cancelInfo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, MainActivity.class);
startActivity(intent);
}
});
}
}
Lastly, this is my SchoolInfo.java class which is to put data to my ArrayList.
package com.example.android.students;
public class SchoolInfos {
private String faculty, department, advisor;
public SchoolInfos() {
}
public SchoolInfos(String faculty, String department, String advisor) {
this.faculty = faculty;
this.department = department;
this.advisor = advisor;
}
public String getFaculty() {
return faculty;
}
public void setFaculty(String faculty) {
this.faculty = faculty;
}
public String getDepartment() {
return department;
}
public void setDepartment(String department) {
this.department = department;
}
public String getAdvisor() {
return advisor;
}
public void setAdvisor(String advisor) {
this.advisor = advisor;
}
#Override
public String toString() {
return "SchoolInfos{" +
"faculty='" + faculty + '\'' +
", department='" + department + '\'' +
", advisor='" + advisor + '\'' +
'}';
}
}
The problem is that, it seems when I add a new entry with add_school_info.xml layout, it actually doesn't show my whole ArrayList. it only shows last entry.

Add this value & method in AdminContent.Java
static final int PICK_ADMIN_DATA = 1; // The request code
ArrayAdapter adapter; // declare globally
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_ADMIN_DATA) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
}
}
}
Change this method
addAdmin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, AdminTab.class);
startActivity(intent);
}
});
To
addAdmin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(context, AdminTab.class);
startActivityForResult(intent, PICK_ADMIN_DATA);
}
});
In AdminTab.Java set result to intent.
addInfo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent();
String faculty = editFaculty.getText().toString();
String department = editDepartment.getText().toString();
String advisor = editAdvisor.getText().toString();
Bundle bundle = new Bundle();
bundle.putString("Faculty", faculty);
bundle.putString("Department", department);
bundle.putString("Advisor", advisor);
intent.putExtras(bundle);
setResult(Activity.RESULT_OK,intent);
finish();
}
}
Then get result from AdminContent.Java OnActivityResult method
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_ADMIN_DATA) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
Bundle bundle = data.getExtras();
String faculty = bundle.getString("Faculty");
String department = bundle.getString("Department");
String advisor = bundle.getString("Advisor");
myArrayList.add(new SchoolInfos(faculty, department, advisor));
adapter.notifyDataSetChanged();
}
}
}
Hope it helps.!

Datepicker and TimePicker dialogs take two clickes of button

So for the life of me I can not find the reason behind needing to click twice on the start date and start time for the picker dialog to open. I have searched these forums many times and they have all been mostly related to edit text fields whereas mine is a simple button but the onClickListener takes two hits. Thanks in advance.

Hmm, your code looks ok. Can you try adding android:focusable="false" to your buttons. I'm curious if the problem is that you're just requesting focus the first click and the second actually initiates the click.
Also, if this doesn't help, can you put some logs in your click listener and also in the public void showTimePickerDialog(View v) { method as well ... to see if it's triggered the first click at all.

Try to add delay on button click it will avoid multi click
date.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
date.setEnabled(false);
showDatePickerDialog(main);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
date.setEnabled(true);
}
}, 100);
}
});

select value from android spinner and display button

I am trying to set reminders. There is a spinner with 5 values (1,2,3,4,5). Let's say if user selects 3 from the spinner there should be 3 "Add Time" buttons displayed. Similarly if user selects 5, five "Add Time" button should be displayed.
User presses "Add Time" button and time picker will be displayed to select time for the reminders. I've created spinner through xml from res/string folder and set an array of 5 item (1,2,3,4,5). I don't know to display these "Add Time" buttons as per the selection of value from the spinner.
Would greatly appreciate any suggestions/guidance.
Thanks a lot...

How i can fit to all devices. Can anyone help?? Thanks in advance.

There are couple of possibilities:
use different xml files for different sizes of screen -> check here http://developer.android.com/guide/practices/screens_support.html
you may use scrollview -> http://developer.android.com/reference/android/widget/ScrollView.html
or simply make your layout fit to the smallest screen size you like to support and then just have "a little" unused space on the larger screens.
It really depends on what you need. Probably the most compatible and advanced solution would be 1.
BUT be aware of the fact that EVERY change on the screen layout has to be duplicated for each xml file following this route!

create xml for each device separately. follow this
second way:
create a parent LinearLayout and pass it to the following method
public static boolean isTabletPC(Context context) {
Display display = ((WindowManager) context
.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
if (display.getWidth() >= 1200) {
isTabletPC = true;
return isTabletPC;
} else {
isTabletPC = false;
return isTabletPC;
}
}
public static void fixUiDeviceDependencies(
Activity act, LinearLayout llParent) {
if (Utilities.isTabletPC(act)) {
Display display = ((WindowManager) act
.getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay();
LayoutParams params = (LayoutParams) llParent
.getLayoutParams();
params.width = display.getWidth() / 2;
llParent.setLayoutParams(params);
}
}
